Strategy Analytics: Apple's iPhone 5 tops world smartphone sales for Q4 2012

Apple iPhone 5 tops world smartphone sales charts for Q4 2012 Strategy Analytics

According to Strategy Analytics, Apple's iPhone 5 was already the best-selling smartphone in the US, and the survey outfit says that it also outsold all other models elsewhere on the planet, too. Cupertino's new bauble sold an estimated 27.4 million units during the period to dethrone the previous quarter's champ, the Samsung Galaxy S III, which landed in around 15.4 million hands globally. To top it off, the iPhone 4S actually shipped an estimated 17.4 million units to bump the Samsung's best-seller down to third place, giving Apple the two most popular handsets on the planet and over 20 percent of the global market. Of course, the Korean maker might be throwing down soon with a new contender, and we know how fast you can go from champ to chump in the smartphone game.

Strategy Analytics: Apple iPhone 5 Becomes World's Best-Selling Smartphone Model in Q4 2012

Boston, MA - February 20, 2013 - According to the latest research from Strategy Analytics, Apple's iPhone 5 overtook Samsung's Galaxy S3 to become the world's best-selling smartphone model for the first time ever in the fourth quarter of 2012. A rich touchscreen, extensive distribution and generous operator subsidies have propelled the iPhone 5 to the top spot.

Neil Shah, Senior Analyst at Strategy Analytics, said, "Apple's iPhone 5 smartphone model shipped an estimated 27.4 million units worldwide during the fourth quarter of 2012. The iPhone 5 captured an impressive 13 percent share of all smartphones shipped globally and it has become the world's best-selling smartphone model for the first time ever. A rich touchscreen design, extensive distribution across dozens of countries, and generous operator subsidies have been among the main causes of the iPhone 5's success. In addition to the iPhone 5, Apple shipped an estimated 17.4 million iPhone 4S units for 8 percent smartphone share globally in Q4 2012. Apple's iPhone 5 and iPhone 4S are currently the world's two most popular smartphone models."

Neil Mawston, Executive Director at Strategy Analytics, added, "Apple's iPhone 5 and iPhone 4S together accounted for 1 in 5 of all smartphones shipped worldwide in Q4 2012. This was an impressive performance, given the iPhone portfolio's premium pricing. We estimate Samsung's Galaxy S3 was the world's third best-selling smartphone model and it shipped 15.4 million units globally, capturing 7 percent share in the fourth quarter of 2012. Samsung's Galaxy S3 has long proven wildly popular with consumers and operators across North America, Europe and Asia. However, global demand for the Galaxy S3 appears to have peaked and Samsung will surely be keen to introduce its rumored Galaxy S4 upgrade in the coming weeks to fight back against Apple's popular iPhone range."

When it comes to genetic code, researchers prove optimum isn't always best

Feb. 18, 2013 ? Imagine two steel springs identical in look and composition but that perform differently because each was tempered at a different rate.

A team of researchers including a Texas A&M University molecular biologist has shown that concept -- that the speed of creation affects performance -- applies to how a protein they studied impacts an organism's circadian clock function. This discovery provides new insights into the significance of the genetic code for controlling the rates at which critically important proteins are synthesized, and could lead to better understanding of cancers and other diseases.

"Living organisms' inner clocks are like Swiss watches with precisely manufactured spring mechanisms," said Matthew Sachs, a professor in the Texas A&M Department of Biology. "For example, if you fast-temper a critical spring, the watch may be unable to keep time, as opposed to slow-tempering it. It's not just about the composition of the components, such as which alloy is used. It's about the manner in which the components are made. Our research says the genetic code is important for determining both composition and fabrication rate for a central component of the circadian clock, and that the fabrication rate also is critical. And that's essentially a discovery."

The research was selected for Advanced Online Publication (AOP) in the journal Nature.

The team, which is led by Yi Liu, a researcher in the Department of Physiology at the University of Texas Southwestern Medical Center, was perplexed when it found a paradoxical result years ago: that optimizing the use of codons (a sequence of three nucleotides that form a unit of genetic code in a DNA or RNA molecule) specifying an essential biological clock component actually abolished the organism's circadian rhythms.

The group's research indicates that the protein in the fungal genus Neurospora they studied, frequency, performs better when the genetic code specifying it has non-optimal codon usage, as is normally found. However, when the genetic code is deliberately altered so that codon usage is optimized, clock function is lost. The reason for this is that non-optimal codon usage slows translation of the genetic code into protein, allotting the frequency protein the necessary time to achieve its optimal protein structure. The team's results also demonstrate that genetic codons do more than simply determine the amino acid sequence of a protein as previously thought: They also affect how much protein can be made as well as the functional quality of that protein.

"We found that less is more, in many cases," Liu said.

Because many genetic diseases are the result of improperly functioning proteins, Sachs says knowledge about how proteins are made and why they have impaired functions is critical to understanding almost all diseases.

"Understanding gene expression is crucial for understanding cancer and other diseases, because ultimately many of these processes involve either mutations of genes or altered expression of genes," said Sachs, who was asked by Liu to help on the research because of his translational expertise in Neurospora.

Video: Sanford: ?I never failed the taxpayer?



>> mark sanford is with us now exclusively. governor, good morning. good to see you.

>> you as well.

>> let's cut right to it. a lot of people are watching saying, you know, everyone does deserve a second chance. everybody deserves a chance to rebuild their life, but not everybody is entitled to run for public office when it relies on public trust especially at a time when our washington institutions have lost so much respect. what would your response be to that?

>> twofold. i have had conversations with a lot of friends back home. the reality of our lives, if we live long enough we're going to fail at something. i absolutely failed in my personal life and my marriage. but one place i didn't ever fail was with the taxpayers. if you look at my 20 years in politics, what you would see is a fairly remarkable consistency in terms of looking out for the taxpayer. the ill that's before us as a civilization, if we don't get our financial house in order, there will be incredible consequences for the dollar, american way of life , all that and more.

>> couple of things about that, though. number one, you paid a fine. ethics charges related to misusing taxpayer funds. you don't have to get into the nitty gritty about it.

>> sure.

>> but doesn't that go against your --

>> no. if we were to get into the nitty gritty , you would find there was no admission of guilt with any of that. in many ways a lawyer would settle a case -- you're a lawyer by training -- this happened but by no means did we agree this happened. and the house, by no means fans, absolved us of all of that.

>> to the larger issue, do you really need to run for public office ? what is this about? you care about debt and deficit. these are issues well discussed in washington .

>> that's just the problem. they are well discussed but all too often too few choose to take real action. and i was actually rated number one in the united states congress by the taxpayer union, citizens gest against government waste, raised the most fiscally conservative governor in the united states . it points to one thing. many people talk about our spending problem in washington , all too few are trying to do something about it.

>> the price of re-entering politics is drudging up all the things we saw. it may be embarrassing to you but to the people around you, including your ex-wife, your family. is it worth it?

>> no. there's definitely pain in the clips you were just showing. but i sat down with the boys. we had a conversation. i said what do you want me to do? if you don't want me to do it, i'm out. their point is no, dad, you've long cared about this stuff. you ought to do it. i also would say i've been on something of a personal journey. i believe if you live long enough, you will fail at something. the higher you rise, the bigger you fall. i failed. in some ways i've come to learn that ultimately our brokenness as human beings is ultimately our connection. and that goes to a larger article of faith and a lot more.

>> and you have been very introspective these past few years. you've talked about that. have you asked yourself, what is this really about? is it about these issues of debt and spending or is this about seeking some kind of personal, political redemption?

>> i think we all hope for redemption in our lives. that is one of the great journeys of our respective lives. but i would say my focus is crystal clear , which is, is part of the cost of re-entering politics a discussion about my personal failure and the consequences thereof? yes. is that painful to me and a lot of others that i love? yes. but i keep going back to we are at a tipping point as a civilization. if we don't get our financial house in order, there will be unbelievable consequences to the folks watching this show right now.

>> mark sanford , it's great to have you here. thank you

PFT: Bucs' Bowers arrested with gun at airport

Morris ClaiborneAP

In the next few days, the NFL will begin descending on Indianapolis, and the miracle of offseason programming known as the Combine will fill TV screens again.

But while the rise of the Underwear Olympics in recent years has been remarkable, don?t be surprised to see more and more of it (programming, if not actual underwear) in the coming years.

Albert Breer of the NFL Network talked to league officials about the future of the combine, and one of the takeaways was how sincerely the league wants to expand the process.

Two years ago, they bought a system of regional workouts from Elite Football Combines, and have turned them into 10 league-sanctioned events from January to March, with a super-regional in Cowboys Stadium on April 7-8 for those who stood out at regionals.

If that sounds a little bit like American Idol to you, it?s not accidental, or the last step. The league?s using those smaller events for fringe prospects as a place to test changes they might implement at future combines, but also as a test of the system that would turn the process of timing and measuring of prospects into an even longer, and more catered-to-television product than it is.

Breer said league officials ?envisioned moving the regionals up on the calendar and perhaps moving Indianapolis back,? allowing the ?winners? of regional combines to advance to the next step.

?The combine won?t be maximized until we find a way to link it with the rest of the journey of these guys,? said Eric Grubman, NFL CFO and executive vice president of business ventures. ?From a football operations standpoint, it?s very well-developed. But it?s an immature property, from a fan-access and fan-appeal standpoint.?

The league has already been open to fiddling with the process, by letting a few reporters into the building during workouts, then a few sponsors and fans, now two days worth of inside access.

It?s only a matter of time before the Combine turns from a long-weekend spectacle, to a miniseries of original programming for the network which might stretch over three months, in which some wide receiver from Southwest Nowhere State might become the latest reality television star.

Rubio Fights the President's 'Half-Baked' Immigration Plan

Things seemed to escalate quickly there. After a copy of the White House's back-up immigration reform bill leaked, Marco Rubio moved quickly to shoot down the bill's proposals to ensure his bipartisan effort remained the favored method to get this deal done.

RELATED: Obama's Immigration Speech Will Include Same-Sex Couples ? and Much More

USA Today's Alan Gomez first reported the White House bill would offer a new visa that would allow illegal immigrants to live and work in the U.S. legally for four years, with an option for an extension. They would have an eight year window to?apply to become a permanent resident if they learn English, U.S. history, and pay back taxes. The bill will also call for enhancements to border security, and an increased amount of immigration judges to deal with the influx of applications. It wasn't a complete draft of the bill and certain key details were left out, most notably what the bill would do to address immigration applications in the future.

RELATED: Obama vs. Senate Republicans: Who Hates the Constitution More?

The New York Times reported Sunday morning these are "early drafts," and that the White House would only submit its bill if the ongoing, separate bipartisan efforts in Congress and the Senate fail to produce anything. Only then would the President push his proposal forward.

RELATED: Rubio Defers His Dream Act

But that didn't stop Marco Rubio from shooting down the President's proposals in a statement issued while he's working on an overseas trip in the Middle East. Rubio is one of the eight Senators currently working on a bipartisan immigration bill. He said the President's proposal was "half-baked," "seriously flawed," and that it "repeats the failures of past legislation." If submitted, Rubio said it would be pronounced dead-on-arrival if proposed to Congress:

"Much like the President's self-described 'stop gap' Deferred Action measure last year, this legislation is half-baked and seriously flawed. It would actually make our immigration problems worse, and would further undermine the American people?s confidence in Washington's ability to enforce our immigration laws and reform our broken immigration system."

"If actually proposed, the President's bill would be dead on arrival in Congress, leaving us with unsecured borders and a broken legal immigration system for years to come."

That 'half-baked' like is a total shot at the President's past, no?

RELATED: What the President's Path to Citizenship Looks Like

It's not surprising that Rubio, a rising face in the Republican party, would shoot this down. He wants, and needs, to support the work he's doing on the Senate deal. He knows Republicans can't afford to lose on immigration reform. Rubio chastised the President for drafting a solution without consulting Republican members of Congress, but a White House official reportedly told the Tampa Bay Times?Republicans were consulted when drafting the bill. They also reiterated that this is merely a draft; it's incomplete legislation.?

RELATED: Obama to Pitch Immigration Reform as a Money Saver

Which is exactly what the White House's official response tried to get across, too. The President will only submit this bill if everything else fails. The only question is how long he's planning on waiting for Congress or the Senate to act. "The president has made clear the principles upon which he believes any common-sense immigration reform effort should be based," White House spokesman?Clark Stevens said in a statement. "We continue to work in support of a bipartisan effort, and while the president has made clear he will move forward if Congress fails to act, progress continues to be made and the administration has not prepared a final bill to submit."

How Cooperative Learning Can Be Used Successfully in The ...

math success How Cooperative Learning Can Be Used Successfully in The Teaching of Mathematics?

In ten years, I spend as much time as I can with the most talented classes teaching logical thinking and deductive unit in Euclidean geometry.

Also, I spend my time defending Class formal geometric proof approach.

One of the activities I always do is to give my students a series of five questions written down as the geometry of the circle.

In Abd, which extended through the point E so that AE @ AB. If a circle drawn through the A, B and D to F sections show that FD FE @.

This strategy has a number of steps, and is used after all the basic instruction and practice geometry circle is complete. This is the last step in my teaching this unit.

Here?s my strategy.

Step 1 students in the class were given five problems similar to the one above for homework. They need to draw diagrams and write each one a testament to all problems.

Step 2 At the beginning of the next class (we have 70 lessons minutes), divide the class into five groups, giving each student a number from one to five.

Step 3 I organized 5-6 tablets / tablet area in my room or in the surrounding area. (I use the mobile plates.) Sam allocate each group in plaque area.

Step 4 Each student group is assigned a number which is the number of problems that will write a complete proof with diagrams in his boat. They will explain their solution to their groups as they go.

Step 5 students in their groups to interact with the teachers? students when necessary to gain more explanation or discussion about the ?correctness? of evidence.

Step 6 Once a student completes his ?proof?, he / she meets with the group in order to allow a ?teacher? again to give his testimony to your problem.

Step 7 movements of a group of teachers to intervene only as a last resort.

Step 8 After the procedure is completed, the class meets in their normal positions, where the teacher asks students to share any problem encountered any evidence innovative.

Step 9 teacher analyzes the process by highlighting all the important issues are not defined in step 8

I feel my students always have a lot of this process. Here are some of the comments made during our evaluation activities.

First I found I get better as a language student explained in ?our?.

Second We all helped each other.

3 Another gave us a good idea.

4 It was more fun than in normal classes.

For me, as a teacher, positive results were:

Communication skills are developing.
The students were on task willingly.
They are taking what they did.
Mentoring between students is beginning to develop.
This strategy can be used successfully in a wide range of subjects, such as simultaneous equations and trigonometric.

Microbes team up to boost plants' stress tolerance

Feb. 17, 2013 ? While most farmers consider viruses and fungi potential threats to their crops, these microbes can help wild plants adapt to extreme conditions, according to a Penn State virologist.

Discovering how microbes collaborate to improve the hardiness of plants is a key to sustainable agriculture that can help meet increasing food demands, in addition to avoiding possible conflicts over scare resources, said Marilyn Roossinck, professor of plant pathology and environmental microbiology, and biology.

"It's a security issue," Roossinck said. "The amount of arable land is shrinking as cities are growing, and climate change is also affecting our ability to grow enough food and food shortages can lead to unrest and wars."

Population growth makes this research important as well, Roossinck added.

"The global population is heading toward 9 billion and incidents of drought like we had recently are all concerns," said Roossinck. "We need to start taking this seriously."

Roossinck, who reports on the findings Feb. 17 at the annual meeting of the American Association for the Advancement of Science in Boston, said that she and her colleagues found an example of a collaboration between plants and viruses that confer drought tolerance to many different crop plants.

The researchers tested four different viruses and several different plants, including crops such as rice, tomato, squash and beets, and showed that the viruses increased the plants' ability to tolerate drought. Virus infection also provided cold tolerance in some cases.

A leafy plant, related to a common weed known as lamb's quarter, was also infected with a virus that caused a local infection. The infection was enough to boost the plant's drought tolerance and may mean that the virus does not have to actively replicate in the cells where the resistance to drought occurs, according to Roossinck.

In studies on plants that thrive in the volcanic soils of Costa Rica and in the hot, geothermal ground in Yellowstone National Park, viruses and fungi work together with plants to confer temperature hardiness, said Roossinck. Researchers found that fungi and a type of grass -- tropical panic grass -- found in Yellowstone National Park grow together in temperatures above 125 degrees Fahrenheit. If the plant and fungus are separated, however, both die in the same heat levels.

Because viruses are often present in plant fungi, Roossinck wondered if viruses played a role in the reaction.

"I noticed that all of the samples from the geothermal soils had a virus, so it seemed worth it to take a deeper look," said Roossinck.

The researchers found that there was no heat tolerance without the virus. Once the researchers cured the fungus of the virus, the plant was unable to withstand the heat. When the virus was reintroduced, the plant regained heat tolerance.

"A virus is absolutely required for thermal tolerance," said Roossinck. "If you cure the fungus of the virus, you no longer have the thermal tolerance."

While researchers do not entirely understand the role of viruses in helping plants withstand extreme conditions, Roossinck said that future research may help the agricultural industry naturally develop hardier plants, rather than rely on chemical solutions that threaten the environment.

"The question is, can we restore the natural level of microbes in plants and grow them better and more tolerant of environmental stress like heat and drought, or pathogens?" Roossinck said. "This may lead to more natural methods of creating crops that are more heat, drought and stress tolerant."

Saint Peter in Rome

What follows is the translation made available by ZENIT of the important speech given by the Holy at the Seminary of the Diocese of Rome on Febuary 14th (pointed out?by?Rorate Caeli). The Holy Father argues against historical critics who have tried to discredit the idea of Peter as the first bishop of Rome: ?Saint Peter writes from Rome. It is important that we already have the Bishop of Rome, we have the beginning of the succession, we have already the beginning of the concrete primacy located in Rome, not only consigned by the Lord, but located here, in this city, in this capital of the world.?

The reflection draws from 1 Peter 1:3-5: ?Peter, apostle of Jesus Christ, To the exiles of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia, chosen and destined by God the Father and sanctified by the Spirit for obedience to Jesus Christ and for sprinkling with his blood: May grace and peace be multiplied to you. Blessed be the God and Father of our Lord Jesus Christ. By his great mercy we have been born anew to a living hope through the resurrection of Jesus Christ from the dead, and to an inheritance which is imperishable, undefiled, and unfading, kept in heaven for you, who by God?s power are guarded through faith for a salvation ready to be revealed in the last time.?

* * *

Eminence,

Dear Brothers in the Episcopate and Priesthood,

Dear Friends!

It is a great joy for me to be with you every year, to see so many young men who walk toward the priesthood, who are attentive to the voice of the Lord, who wish to follow this voice and seek the way to serve the Lord in this our time.

We heard three verses of the First Letter of Saint Peter (cf. 1:3-5). Before going into this text, it seems important to me to be attentive to the fact that it is Peter who is speaking. The first two words of the Letter are ?Petrus apostolus? (cf. v. 1): he speaks, and he speaks to the Churches in Asia and calls the faithful ?chosen and exiles of the Dispersion? (ibidem). Let us reflect a bit on this. Peter speaks, and he speaks ? as we hear at the end of the Letter ? of Rome, which he calls ?Babylon? (cf. 5:13). Peter speaks: it is almost a first encyclical, with which the first Apostle, vicar of Christ, speaks to the Church of all times.

Peter, apostle. Hence, he speaks who has found Christ Jesus the Messiah of God, who has spoken as the first in the name of the future Church: ?You are the Christ, the Son of the living God? (cf. Matthew 16:16). He is speaking who has introduced us to this faith. He speaks to whom the Lord said: ?I will give you the keys of the kingdom of heaven? (cf. Matthew 16:19), to whom he entrusted his flock after the Resurrection, saying to him three times: ?Feed my lambs, tend my sheep? (cf. John 21:15-17). Speaking also is the man who fell, who denied Jesus and who had the grace to see Jesus? glance, to be touched in his heart and to have found forgiveness and a renewal of his mission. However, it is important that this man, full of passion, of desire for God, of desire for the kingdom of God, for the Messiah, that this man who found Jesus, the Lord and the Messiah, is also the man who sinned, who fell, and yet he remained under the eyes of the Lord and thus remains responsible for the Church of God, he remains entrusted by Christ to be the bearer of his love.

Peter the apostle is speaking, but the exegetes tell us: it is not possible that this Letter is of Peter, because the Greek is so good that it cannot be the Greek of a fisherman of the Lake of Galilee. And not only the language, the structure of the language is optimal, but also the thought is now quite mature, there are already concrete formulas in which the faith and the reflection of the Church is condensed. Hence, they say: it is already a state of development that cannot be Peter?s. How to respond? There are two important positions: first, Peter himself ? namely the Letter ? which gives us a key because at the end of the writing he says: ?I have written to you through Silvanus ? by Silvanus.? This through [by] can mean several things: it can mean that he [Silvanus] transports, transmits; it can mean that he helped in the writing; it can mean that he was really the practical writer. In any case, we can conclude that the Letter itself tells us that Peter was not alone in writing this Letter, but expresses the faith of a Church that is already on the path of faith, an ever more mature faith. He does not write by himself, an isolated individual, he writes with the help of the Church, of the persons who help to deepen the faith, to enter into the profundity of its thought, of its reasonableness, of its profundity. And this is very important: Peter does not speak as an individual, he speaks ex persona Ecclesiae, he speaks as man of the Church, certainly as a person, with his personal responsibility, but also as a person who speaks in the name of the Church: not just his private ideas, not as a genius of the 19th century who wished to express only personal, original ideas, which no one was able to express before. No. He does not speak as an individualistic genius, but speaks in fact in the communion of the Church. In Revelation, in the initial vision of Christ, it is said that the voice of Christ is the sound of many waters (cf. Revelation 1:15). This means that the voice of Christ gathers all the waters of the world, he bears in himself all the living waters that give life to the world; he is Person, but in fact this is the greatness of the Lord, who bears in himself the whole river of the Old Testament, in fact of the wisdom of the peoples. And what is said here about the Lord is true, in another way, also for the apostle, who does not wish to say his own word, but really bears in himself the waters of the faith, the waters of the whole Church, and thus, in fact, of fertility, of fecundity and precisely because of this, he is a personal witness that opens to the Lord, and so becomes open and wide. Therefore, this is important.

Then it also seems important to me that in the conclusion of the Letter Silvanus and Mark are named, two persons who also belong to Saint Paul?s friendships. Thus, through this conclusion, the worlds of Saint Peter and Saint Paul go together: it is not an exclusively Petrine theology against a Pauline theology, but it is a theology of the Church, of the faith of the Church, in which there is diversity ? certainly ? of temperament, of thought, of style ? in speaking between Paul and Peter. It is good that these diversities exist, also today, diverse charisms, diverse temperaments; however, they are not conflicting and are united in the common faith.

I would also like to say one thing: Saint Peter writes from Rome. It is important that we already have the Bishop of Rome, we have the beginning of the succession, we have already the beginning of the concrete primacy located in Rome, not only consigned by the Lord, but located here, in this city, in this capital of the world. How did Peter come to Rome? This is a serious question. The Acts of the Apostles tell us that, after his escape from Herod?s prison, he went to another place (cf. 12:17) ? eis eteron topon ? it is not known to which other place; some say Antioch, some say Rome. In any case, in this chapter, it is also said that, before escaping he entrusted the Judeo-Christian Church, the Church of Jerusalem, to James and, though entrusting it to James, he still remained Primate of the universal Church, of the Church of the pagans, but also of the Judeo-Christian Church. And here in Rome he found a large Judeo-Christian community. The liturgists tell us that in the Roman Canon there are traces of the typically Judeo-Christian language; thus we see that both parts of the Church were in Rome: the Judeo-Christian and the pagan-Christian, united, expression of the universal Church. And certainly for Peter the passage from Jerusalem to Rome is the passage to the universality of the Church, the passage of the Church of the pagans and of all times, to the Church which is also always of the Jews. And I think that, going to Rome, Saint Peter not only thought of this passage: Jerusalem/Rome, Judeo-Christian Church/universal Church. He certainly also remembered the last words Jesus addressed to him, reported by Saint John: ?At the end, you will go where you do not wish to go. You will stretch out your hands, and another will gird you? (cf. John 21:18). It is a prophecy of the crucifixion. The philologists show us that it is a precise, technical expression, this ?stretching out the hands,? for the crucifixion. Saint Peter knew that his end would be martyrdom, that it would be the cross. And thus, he would be in the complete following of Christ. Hence, by going to Rome he was certainly going also to martyrdom: martyrdom awaited him in Babylon. Therefore, the primacy has this content of universality, but also a martyrological content. From the beginning, Rome was also a place of martyrdom. Going to Rome, Peter accepts again this word of the Lord: go to the Cross, and he also invites us to accept the martyrological aspect of Christianity, which can have many different forms. And the cross can have many different forms, but no one can be a Christian without following the Crucified One, without also accepting the martyrological moment.

After these words on the sender, a brief word also on the persons to whom it is written. I have already said that Saint Peter describes those to whom he writes with the words ?eklektois parepidemois,? ?to the chosen that are dispersed exiles? (cf. 1 Peter 1:1). We have again this paradox of glory and cross: chosen but dispersed and exiles. Chosen: this was Israel?s title of glory: we are the chosen, God has chosen us little people not because we are great ? says Deuteronomy ? but because He loves us (cf. 7:7-8). We are chosen: Saint Peter now transfers this to all the baptized, and the content itself of the first chapters of his First Letter is that the baptized enter in the privileges of Israel, they are the new Israel. Chosen: it seems to me worthwhile to reflect on this word. We are chosen. God has always known us, before our birth, our conception. God willed me to be a Christian, a Catholic; He willed me to be a priest. God has thought of me, has sought me among millions, among so many. He has seen me and chosen me, not for my merits, of which there were none, but because of his goodness; He wanted me to be bearer of his election, which is always also a mission, above all a mission, and responsibility for the others. Chosen: we must be grateful and joyful for this fact. God has thought of me, has chosen me as a Catholic, as bearer of his Gospel, as priest. It seems to me worthwhile to reflect several times on this, and to re-enter again in this fact of his election: He has chosen me, He has willed me. Now I respond.

Perhaps today we are tempted to say: you do not want to be joyful for being chosen, it would be triumphalism. It would be triumphalism if we thought that God chose me because I am so great. This would really be mistaken triumphalism. However, to be happy because God has willed me is not triumphalism, but gratitude, and I think that we must learn this joy again: God willed that I be born so, in a Catholic family, that I know Jesus from the beginning. What a gift to be willed by God, so that I have been able to know his face, I have been able to know Jesus Christ, the human face of God, the human history of God in this world! To be joyful because he chose me to be Catholic, to be in this Church of his, where subsistit Ecclesia unica; we must be joyful because God has given us this grace, this beauty of knowing the fullness of the truth of God, the joy of his love.

Chosen: it is at the same time a word of privilege and of humility. But ?chosen? is ? as I said ? accompanied by ?parapidemois,? dispersed, exiles. As Christians we are dispersed and exiles; we see that today Christians are the most persecuted group in the world because they do not conform, because they are a stimulus against the tendencies of egoism, materialism, of all these things.

We Christians are certainly not only exiles; we are also Christian nations, we are proud of having contributed to the formation of a culture, there is a healthy patriotism, a healthy joy of belonging to a nation that has a great history of culture, of faith. Yet, as Christians, we are always exiles ? the fate of Abraham, described in the Letter to the Hebrews. As Christians we are in fact today always exiles. In work places Christians are a minority, they are in a situation of exile; it is a wonder that one can still believe and live like this today. This also belongs to our life: it is a way of being with Christ Crucified, this being exiles, not living in the way that everyone lives, but living ? or at least trying to live ? according to his Word, in great difference from what everyone says. And this is in fact characteristic of Christians. All say: ?but everyone does so, why not I?? No, not I, because I want to live according to God. Saint Augustine said once: ?Christians are those that do not have their roots down here as do the trees, but they have their roots above, and they live not in the natural gravitation towards below.? Let us pray to the Lord that He help us to accept this mission of living as dispersed persons, as a minority, in a certain sense; of living as exiles and yet of being responsible for others and, precisely in this way, giving strength to the good of our world.

We come finally to the three verses of today. I would only like to stress or, let us say, interpret as well as I can, three words: the word regenerated, the word inheritance, the word custodians of the faith. Regenerated ? anaghennesas, says the Greek text ? means: to be Christian is not simply a decision of my will, an idea of mine. I see that it is a group that please me, so I become a member of this group, I share their objectives, etc. No: to be Christian is not to enter in a group to do something, it is not just an act of my will, not primarily of my will, of my reason: it is an act of God. Regenerated does not concern only the sphere of the will, of thought, but the sphere of being. I am reborn: this means that to become Christian is first of all passive; I cannot make myself a Christian, but I come to be reborn, I come remade by the Lord in the profundity of my being. And I enter this process of rebirth, I let myself be transformed, renewed, regenerated. This seems very important to me: as a Christian I do not have an idea that I share with some others, and if I no longer like them, I can leave. No: in fact it concerns the depth of my being, that is, to become a Christian begins with an action of God, above all an action of His, and I let myself be formed and transformed.

It seems to me this is matter for reflection, for meditation, precisely in a year in which we reflect on the Sacraments of Christian initiation. To meditate on this passive and active depth of the regenerated being, of the becoming of a whole Christian life, of letting myself be transformed by his Word, for the communion of the Church, for the life of the Church, for the signs with which the Lord works in me, works with me and for me. And to be reborn, to be regenerated, indicates also that I thus enter into a new family: God, my Father, the Church, my Mother, other Christians, my brothers and sisters. Hence, to be regenerated, to let oneself be regenerated also implies letting oneself be inserted willingly in this family, to live for God the Father and from God the Father, to live from communion with Christ his Son, who regenerates me by his Resurrection, as the Letter says (cf. 1 Peter 1:3), to live with the Church letting myself be formed by the Church in so many senses, in so many ways, and to be open to my brothers, to really recognize in others my brothers, who are regenerated with me, transformed, renewed; one bears responsibility for the other. Hence a responsibility of Baptism which is a process of a whole lifetime.

Second word: inheritance. It is a very important word in the Old Testament, where Abraham is told that his seed will inherit the earth, and this was always his promise to his own: You will have the earth, you will be heirs of the earth. In the New Testament, this word becomes a word for us: we are heirs, not of a determined country, but of God?s land, of God?s future. Inheritance is something of the future, and so above all, this word says that as Christians we have the future: the future is ours, the future is God?s. And thus, being Christians, we know that the future is ours and the tree of the Church is not a dying tree, but a tree that always grows again. Therefore, we have reason not to let ourselves be affected ?as Pope John said ? by the prophets of gloom, who say: well, the Church is a tree that came from the mustard seed, which grew in two millennia, which now has time behind her, and now is the time in which she dies.? No. The Church always renews herself, is always reborn. The future is ours. Of course, there is a false optimism and a false pessimism. A false pessimism that says: the time of Christianity has ended. No: it begins again! The false optimism was that after the Council, when convents were closing, seminaries were closing, and they said: but ? nothing is wrong, everything is all right ? No! Everything is not all right. There are also grave, dangerous falls, and we must acknowledge them with healthy realism, that this is not right, it is not all right when things are mistaken. But at the same time we must also be certain that if here and there the Church is dying because of men?s sins, because of their unbelief, at the same time she is reborn. The future is truly God?s: this is the great certainty of our life, the great, true optimism that we know. The Church is the tree of God who lives in eternity and bears in herself eternity and the true inheritance: eternal life.

And, finally, custodians of the faith. The text of the New Testament, of the Letter of Saint Peter, uses here a strange word, phrouroumrnoi, which means: there are ?the guardians,? and the faith is as ?the guardian? that guards the integrity of my being, of my faith. This word interprets above all the ?guardians? of the doors of a city, where they are and guard the city, so that it is not invaded by powers of destruction. In this way the faith is ?guardian? of my being, of my life, of my inheritance. We must be grateful for this vigilance of the faith that protects us, helps us, guides us, gives us security: God does not let me fall out of his hands. Custodians of the faith: so I end. Speaking of the faith I must always think of that sick Syro-Phoenician woman who, in the midst of the crowds, found access to Jesus, touches him to be cured, and is cured. The Lord says: ?Who touched me?? They say to him: ?But Lord, everyone touches you, how can you ask, who has touched me?? (cf. Mark 7:24-30). But the Lord knows: there is a way of touching Him, superficial, external, which has really nothing to do with a real encounter with Him. And there is a way of touching Him profoundly. And this woman really touched him: touched Him not only with her hand, but with her heart and thus she received the healing strength of Christ, touching Him really from within, from faith. This is faith: to touch with the hand of faith, to touch Christ with our heart and thus enter into the strength of his life, the healing strength of the Lord. And we pray to the Lord that we will be able to touch Him ever more and so be healed. We pray that He not let us fall, that He hold us always by the hand and so guard us for the true life. Thank you.

Pistorius, girlfriend were planning future: uncle

JOHANNESBURG (Reuters) - South African athlete Oscar Pistorius was planning a future with girlfriend Reeva Steenkamp, who he is accused of shooting in cold blood this week, his uncle said on Saturday.

"We are in a state of total shock - firstly about the tragic death of Reeva who we had all got to know well and care for deeply over the last few months," Anthony Pistorius said in a statement released by his nephew's agent.

"They had plans together and Oscar was happier in his private life than he had been for a long time," he said.

Pistorius, 26, was charged on Friday with murdering Steenkamp in the early hours of the previous day. He broke down during a 40-minute bail hearing at a Pretoria court but was not asked to enter a plea.

Prosecutors alleged the shooting was premeditated - a charge that could put Pistorius behind bars for life if he is convicted.

Anthony Pistorius reiterated the family's belief that the track star - a double amputee who became one of the biggest names in world athletics - had not deliberately shot Steenkamp, a 30-year-old model. Initial reports suggested he may have mistaken Steenkamp for an intruder.

???? ????

Description: The talk aims to provide an introduction into the Windows Phone 7 (WP7) security model to allow security professionals and application developers understand the unique platform security features offered. Currently very little public information is available about Windows Phone 7 OS security preventing adequate determination of the risk exposed by WP7 devices.
The ever increasing challenges and stages of exploitation an attacker has to overcome to achieve full compromise will be discussed. The talk will outline the implementation of these security features and will demonstrate weaknesses and vulnerabilities an attacker could use to bypass the multiple levels of platform security.
A number of OEM manufacturer weaknesses, "features?" will be discussed and a demonstration of how these "features" can be abused in conjunction with conventional exploits to achieve full compromise of the phone will be performed. The talk will demonstrate how OEM phone manufacturers can weaken the security posture of an otherwise strong granular security model and also demonstrate how targeted attacks can be made which leverage this OEM "functionality" to compromise sensitive information.
Alex Plaskett held this talk at the DeepSec 2011 security conference.

Who is 'El Chapo' Guzman, Public Enemy Number One?

Chicago has resurrected its "Public Enemy No. 1" designation, not used since it was created for Al Capone, to label Mexican drug kingpin Joaquin "El Chapo" Guzman Luera.

By Michael Tarm,?Associated Press / February 15, 2013

Joaquin 'El Chapo' Guzman Loera, seen here after his 1993 arrest, escaped from a maximum security federal prison in 2001 and continues to be a fugitive. On Feb. 14, Chicago announced that Guzman, the head of Mexico's Sinaloa crime cartel, is their new Public Enemy No. 1.

Damian Dovarganes / AP / File

Enlarge

A drug kingpin in Mexico who has never set foot in Chicago has been named the city's new Public Enemy No. 1 ? the same notorious label assigned to Al Capone at the height of the Prohibition-era gang wars.

Skip to next paragraph

' + google_ads[0].line2 + '
' + google_ads[0].line3 + '

'; } else if (google_ads.length > 1) { ad_unit += ''; } } document.getElementById("ad_unit").innerHTML += ad_unit; google_adnum += google_ads.length; return; } var google_adnum = 0; google_ad_client = "pub-6743622525202572"; google_ad_output = 'js'; google_max_num_ads = '1'; google_feedback = "on"; google_ad_type = "text"; google_adtest = "on"; google_image_size = '230x105'; google_skip = '0'; // -->

The Chicago Crime Commission announced the move Thursday, saying it considers Joaquin "El?Chapo" Guzman even more menacing than Capone because he's the leader of the Sinaloa cartel, which supplies most of the narcotics sold in the city.

"What Al Capone was to beer and whiskey during Prohibition, Guzman is to narcotics," said Art Bilek, the commission's executive vice president. "Of the two, Guzman is by far the greater threat. ... And he has more power and financial capability than Capone ever dreamed of."

The commission ? a non-government body that tracks city crime trends ? designated Capone Public Enemy No. 1 in 1930. It has declared other outlaws public enemies, but Capone was the only one deemed No. 1.

Until now.

Guzman is thought to be holed up and guarded by a personal army in a Mexican mountain hideaway. And there's nothing to indicate he's ever been anywhere near Chicago, according to the Drug Enforcement Administration, which joined the commission in affixing the title to Guzman.

Still, for all practical purposes, Guzman should be treated as a local Chicago crime boss for the havoc his cartel creates in the nation's third-largest city, said the head of the DEA's Chicago office, Jack Riley.

The point of singling out Guzman now, added Bilek, is to inspire more public support for going after him.

"Ninety-nine percent of the people in the United States have never heard of this man," he said. "Concerted action ... must be taken now against Guzman before he establishes a bigger network and a bigger empire in the United States."

Capone based his bootlegging and other criminal enterprises in Chicago during Prohibition, when it was illegal to sell alcohol in the U.S. He gained the greatest notoriety for the 1929 St. Valentine's Day Massacre when assassins wielding Thompson machine guns shot dead seven of his rivals in a downtown garage.

Yet Riley said Guzman ? whose nickname means "shorty" in Spanish ? is more ruthless than Capone, whose nickname was "Scarface."

"If I was to put those two guys in a ring,?El?Chapo?would eat that guy (Capone) alive," Riley told The Associated Press in a recent interview at his office, pointing at pictures of the men.

Riley described Chicago as one of Sinaloa's most important cities, not only as a final destination for drugs but as a hub to distribute them across the U.S.

"This is where Guzman turns his drugs into money," he said.

Cartels, blamed for more than 50,000 deaths in Mexico in recent years, are rarely directly linked to slayings in Chicago. But Bilek said Thursday that cartel-led trafficking is an underlying cause of territorial battles between street gangs that are responsible for rising homicide rates.

Guzman "virtually has his fingerprints on the guns that are killing the children of this city," Bilek told a news conference.

The cartel leader, who has been in hiding since escaping from a Mexican prison in a laundry cart in 2001, is one of the world's most dangerous and most wanted fugitives. He's also one of the richest: Forbes magazine has estimated his fortune at $1 billion.

Now in his mid-50s, Guzman has been indicted on federal trafficking charges in Chicago and, if he is ever captured alive, U.S. officials want him extradited here to face trial. The U.S. government has offered a $5 million reward for his capture.

"His time is coming," Riley said. "I can't wait for that day."

It was only a coincidence, Bilek said, that the announcement naming Guzman Public Enemy No. 1 came on the anniversary of the St. Valentine's Day Massacre, which raised public pressure to capture Capone.

Within two years of being designated Public Enemy No. 1 in 1930, Capone ? who also once seemed invincible ? had been captured, convicted and imprisoned.

With the same label now attached to Guzman, Bilek said, "we hope the same thing will happen to him."

Pakistani tribesmen pushing Taliban to talk peace

PESHAWAR, Pakistan (AP) ? Five years after setting up an umbrella organization to unite violent militant groups in the nation's tribal regions, the Pakistani Taliban is fractured, strapped for cash and losing support of local tribesmen frustrated by a protracted war that has forced thousands from their homes, analysts and residents of the area said.

The temperamental chief of the group known as the Tehrik-e-Taliban Pakistan (TTP), Hakimullah Mehsud, recently offered to start peace talks with the government, raising the prospect of a negotiated end to Pakistan's war against insurgents in a lawless region that runs the length of the border with Afghanistan.

The group's offer of sanctuary to Afghanistan's Taliban has been one of the most divisive issues in U.S.-Pakistan relations and has confounded efforts to get the upper hand against Afghan insurgents after more than 11 years of war.

Pakistan denies providing outright military and financial help to militants fighting in Afghanistan. With 120,000 Pakistani soldiers deployed in the tribal regions, Pakistan has waged its own bloody battle against insurgents that has left more than 4,000 soldiers dead.

In interviews with analysts, residents and militant experts, Mehsud's network has emerged as a narrow collection of insurgents ? often with links to criminal gangs ? that has only limited influence in a vast tribal region overrun by scores of insurgent groups led by commanders with disparate agendas and varying loyalties.

Rather than a precursor to peace, Mehsud's offer to talk peace is an attempt to regain stature, silence critics and gain concessions from a weak government heading into nationwide elections, according to those familiar with the militant organization.

Taliban spokesman Ehsanullah Ehsan has repeatedly denied reports of divisions within the TTP, including reported challenges to Mehsud's leadership.

But Amir Rana, director of the Pakistan Institute of Peace Studies, said Mehsud's offer to talk was an attempt to divert attention from internal rifts that are ripping the organization apart and diminishing its influence. Meshud speaks for fighters restricted to his own tribe, based in North and South Waziristan, he said.

"There is a lot of tension within the TTP. This peace offer I think basically comes from Hakimullah Mehsud and the Mehsud commanders," Rana said.

Some of his most powerful commanders have broken away and set up their own fiefdoms in other parts of the tribal area, he said.

Mehsud's fighters are believed to number in the thousands, but there are no reliable figures to measure the size of his force.

Former intelligence officials, Taliban and residents of the area say Mehsud also has a large number of foreign fighters in his North Waziristan hideouts. Many are Uzbeks and other Central Asians belonging to the outlawed Islamic Movement of Uzbekistan and mostly disliked by local residents.

"The Taliban's offer for peace talks is more of a ploy to gain legitimacy and a public relations tactic than a sincere move to end violence," militant expert and author Zahid Hussain wrote in a local newspaper this week.

Hussain portrayed Mehsud's Taliban as killers and criminals who are demanding negotiations on their own terms, including the release of prisoners who spearheaded the 2009 Taliban takeover of the Swat region in northeastern Pakistan and who admitted beheading opponents. In brazen disregard for Pakistani law, the video in which they offered peace talks featured convicted killer Adnan Rashid, who escaped from death row during a jailbreak by the Taliban last year.

Hussain called the video a "grotesque joke" and criticized the government's willingness to talk with Mehsud's Taliban.

"Some political leaders are shamelessly calling on the state to surrender to the very criminals who have killed thousands of Pakistanis in suicide bombings, beheaded soldiers and bombed schools," he said.

Two dozen political parties including the ruling Pakistan People's Party agreed in a day-long meeting Thursday to pursue talks with the Taliban, including the secular-leaning Awami National Party that rules the Khyber Pukhtunkhwa province where the tribal regions are located. They didn't offer details of how they would go about it.

"We have to try to find peace. It is not a question of giving them legitimacy. Their forces are there and when they come to the negotiation table they are recognizing the writ of the government," provincial information minister Iftikar Hussain, whose son was killed by Taliban insurgents, told The Associated Press on Wednesday.

Previous agreements between various Taliban factions have collapsed.

The TTP in North Waziristan is looking for talks because it is losing the support of the local people, according to a privately funded think tank in the Pakistani capital devoted to understanding the tribal regions.

"They are weak, there is infighting," said Mansour Mehsud, director of research at the FATA Research Center named for the Federally Administered Tribal Areas.

Pakistan's tribal regions have a special status under Pakistani law that allows tribal traditions and customs to rule. Many of the laws and rules applying to the tribal area date back to the early 20th century when the British ruled the subcontinent. Unable to control the tribesmen, the British made agreements that allowed them safe passage through tribal territory.

"They used to have the support of most people but not anymore," said Mehsud, who has no relation to the TTP leader although he shares the same tribal links. "People used to think that they would bring justice based on the Quran but instead fighting has displaced hundreds of thousands of people."

Mehsud said the Pakistani Taliban also were running out of money and that extortion and kidnappings had become one of their biggest sources of income.

A wealthy trader living on the edge of the tribal area, who was afraid to give his name because he feared retribution, said the Taliban swindled thousands of dollars from him. He said he was threatened, his family was terrorized and then a bomb exploded at his home, seriously wounding his niece.

He said other businessmen told him that they too had paid large sums of money to the Taliban. In his tribal culture, he said it is shameful to admit to being robbed because it is seen as a sign of weakness, so no one has said anything.

Perry ends California jobs trip as critics question payoff

by BRAD WATSON

WFAA

Posted on February 13, 2013 at 6:14 PM

Updated today at 2:10 AM

Gov. Rick Perry's West Coast swing to woo businesses from California to Texas has come to an end.?

California's Democratic Gov. Jerry Brown is probably glad to see Perry go, especially after his crude evaluation of the Texas governor's radio ad campaign, calling it "barely a fart."?

Texas One, a public-private partnership set up by the legislature as a nonprofit and run through Perry's office, arranged for the radio ads... and the trip. Texas One is funded by companies, local governments and chambers of commerce wanting companies to expand or relocate to Texas.

A spokesman for the governor says following a 2010 Texas One visit to California, led by Perry, companies recruited decided to expand in Texas. In all of his trips to California, Perry spokesman Josh Havens says the governor has brought 4,445 jobs to Texas.

However, critics in California and in Texas think Perry's latest trip was about more than just jobs.

Perry loves to extol Texas' pro-business outlook, touting its low taxes and regulation outside the state, just as he does frequently at home.

In a Wednesday conference call from Laguna Beach with reporters he said, "Gov. Brown may call it 'poaching;' I just call it giving people an option of where they can locate their business and keep more of their money."

In stops at San Francisco, the Silicon Valley and the Los Angeles area, Perry pointed to Texas' superior job creation and California's recent increase in sales and income taxes.

"This isn't about bashing California," Perry said. "It's about promoting Texas and the economic climate we've created."??

But some Perry critics in California think his trip is more about trying to raise sagging Texas poll numbers, which show a majority of Republican voters want someone else to run for governor next year.

Dan Walters, a political columnist with the Sacramento Bee said in an online video: "He can think of nothing better to get Texans on his side than to tweak those crazy people out there in California, which all good Texans love to hate."

In Austin, Democratic lawmakers called the trip "political theater." Sen. Wendy Davis (D - Fort Worth) said if Perry is concerned about jobs, he could help restore some 25,000 school jobs lost in 2011 budget cuts.

"If Gov. Perry really wanted to do something to grow and continue to advance the business community in Texas, he'd be here helping us work on that," she said.

But Perry, the former Texas A&M yell leader, feels very comfortable being the top cheerleader for the state's business climate.

How Facebook Makes Graph Search Safer for Teens

Teens don't get equal treatment on Facebook's Graph Search. And for parents, that can be reassuring.

Facebook has been slowly rolling out the expanded search feature called Graph Search that lets users discover interesting connections among their friends, and depending on privacy settings, among friends of friends, which is likely to include strangers.

Facebook already limits sharing to friends of friends for all?teens ?(ages 13 to 17), meaning kids can't share to the public. And now Facebook has further limited its Graph Search for young people to show results only for those that fall into the same age group, the company said in a post. So if your daughter searches for "my friends who like Justin Bieber," she won't see that her mom's friends are some of his biggest fans.

Facebook also reminded users to review their Activity logs and About me sections to remove old posts and photos or limit who can see them. For a step-by-step guide, see?Facebook Graph Search: 3 Steps to Shield Privacy.

Obama attempting to change face of the judiciary

WASHINGTON (AP) ? President Barack Obama is trying to change the face of a federal judiciary that has a long tradition of white men passing judgment on parties from all walks of life ? if he can get his nominees past the Senate.

Republicans have used the powers accorded the Senate minority party to slow Obama's influence on the federal bench. But recent changes to Senate rules suggest the process may begin to move faster, at least at the lower, U.S. District Court level.

Under a recent bipartisan agreement, the Senate will limit debate on district court judge nominees to two hours, far below the 30 hours that used to be allowed. The hope is that will curtail a tradition that dates back to the Clinton administration of the president's opposing party stalling judicial nominees.

Democrats also used the tactic for some of President George W. Bush's nominees, but the delays have been particularly long under Obama.

Nearly half of Obama's nominees have waited for more than 100 days for confirmation votes, while less than 10 percent of Bush's waited that long, according to White House figures. Most of the Bush nominees were approved in less than a month after clearing committee, the White House said.

Michael L. Shenkman, a fellow at the Center for Law and Politics at Columbia Law School who worked on Obama's judicial nominations team in the first two years of his presidency, calculated that district judge vacancies across the country represented more than 275 lost years of judicial work and $160 million in wasted public resources during Obama's first term.

"Having an empty bench means people don't get their cases heard," Shenkman said, adding that federal law requires that judges give priority to criminal cases, so civil cases can face repeated delay. "It makes litigation more frustrating and more expensive."

Nationwide, 90 out of 874 federal judgeships are vacant, with 31 of those vacancies labeled emergencies by the judiciary because of heavy caseloads. The Senate Judiciary Committee approved 13 of Obama's nominees Thursday.

White House press secretary Jay Carney argues that the judges approved by the committee are "extremely well-qualified" and "reflect the president's unprecedented commitment to a judiciary that reflects the nation it serves." The group of 13 includes eight women, six minorities and one openly gay candidate.

"This needless delay is unacceptable, and these nominees deserve immediate consideration by the full Senate," Carney said.

White House officials express little hope that the Senate will change its ways.

They point to Wednesday's confirmation of William Kayatta of Maine to the 1st U.S. Circuit Court of Appeals in Boston. Kayatta's nomination a year ago was supported by both of Maine's Republican senators. But other Republicans in the Senate refused to agree to a vote so Obama had to renominate Kayatta again this year, even though he ultimately passed without much controversy and 88 votes in support.

Caroline Fredrickson, president of the American Constitution Society for Law and Policy, says the change in Senate rules still won't impact nominees to the federal circuit, where appeals are heard and judges have more influence. "Where I'm worried is that on the circuit court nominees there will be a lot of delay and obstruction that's completely unrelated to anyone's merits," she said.

Despite the delays, Obama was able to make some progress on diversity in his first term, with more black, Hispanic and openly gay federal judges confirmed than in two terms Bush, according to the White House. Nearly half of Obama's confirmed judges have been women, compared with about a quarter for Bush and Clinton, the White House said.

Obama hopes to build on that diversity in his second term. Only seven of the 36 nominees the president currently has pending are straight white men. Compare that to the makeup of the roughly 780 judges currently active on the federal bench, where 425 are white men, according to the Federal Judicial Center. There are small percentages of minorities ? 96 black judges, 70 Hispanic and 17 Asian.

In the 8th U.S. Circuit Court of Appeals based in St. Louis, a group called the Infinity Project was formed to promote more gender equality, with just one woman ever having been appointed to serve on the circuit. Executive Director Debra Fitzpatrick argues that a diverse bench enhances a court's legitimacy by reflecting the population on which it passes judgment.

"You can't always predict when and how and in what ways a person's personal experience will illuminate a case," Fitzpatrick said. She pointed to the case of an Arkansas prisoner named Shawanna Nelson convicted of check and credit card fraud who filed a lawsuit over being shackled to a hospital bed while in labor.

Nelson's attorney, Cathleen Compton, grew frustrated as she argued before the panel why her client, a nonviolent offender, didn't pose a flight risk that required shackling. "I'm a little disadvantaged here, or maybe it's you that are disadvantaged, because I've given birth and you haven't. I can tell you that a woman about to deliver a nearly 10-pound baby is not going anywhere," she said.

The appeals court sided with Nelson, in an opinion written by the circuit's sole woman, Clinton-appointed Judge Diana Murphy.

Two weeks ago, Obama nominated another woman, Iowa public defender Jane Kelly, to the 8th Circuit.

Understanding why cells stick

Feb. 14, 2013 ? Research carried out by scientists at Georgia Institute of Technology and The University of Manchester has revealed new insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It?s thought abnormalities in their ability to do play an important role in a broad range of disorders, including cardiovascular disease and cancer.

The study?s findings are outlined in the journal Molecular Cell and describe a surprising new aspect of cell adhesion involving the family of cell adhesion molecules known as integrins, which are found on the surfaces of most cells. The research uncovered a phenomenon termed ?cyclic mechanical reinforcement,? in which the length of time during which bonds exist is extended with repeated pulling and release between the integrins and ligands that are part of the extracellular matrix to which the cells attach.

Professor Martin Humphries, the Dean of the Faculty of Life Sciences at Manchester led the UK research team and says the study suggests some new capabilities for cells: ?This paper identifies a new kind of bond that is strengthened by cyclical applications of force, and which appears to be mediated by complex shape changes in integrin receptors.??

He continues: ?The findings also shed light on a possible mechanism used by cells to sense extracellular topography and to aggregate information through ?remembering? multiple interaction events.?

The cyclic mechanical reinforcement allows force to prolong the lifetimes of bonds, demonstrating a mechanical regulation of receptor-ligand interactions and identifying a molecular mechanism for strengthening cell adhesion through cyclical forces.

Cheng Zhu, a professor in the Coulter Department of Biomedical Engineering at Georgia Tech and Emory University led the U.S. research: ?Many cell functions such as differentiation, growth and the expression of particular genes depend on cell interaction with the ligands of the intracellular matrix. The cells respond to their environment, which includes may mechanical aspects. This study has extended our understanding of how connections are made and how mechanical forces regulate interactions.?

Using delicate force measuring equipment, researchers in Professor Zhu?s lab and the laboratory of Professor Andres Garcia from the Woodruff School of Mechanical Engineering at Georgia Tech, collaborated to study adhesion between integrin and fibronectin, a protein component of the extracellular matrix. What they found was that cyclic forces applied to the bond switch it from a short lived state ? with lifetimes of about one second ? to a long-lived state that can exist for more than a hundred seconds.

Professors Zhu and Garcia alongside Georgia Tech graduate students Fang Kong, William Parks and David Dumbauld and postdoctoral fellow Zenhai Li used two different mechanical techniques to study the strength of bonds between integrin and fibronectin. One technique measured the bond strengths in purified molecules, while the other studied the effects of them in their native cellular environment.

Professor Zhu explains: ?We have very precise force transducers that allow us to measure force on the scale of pico-newtons. We prepare the samples in such a way that we engage only one bond, we then control the application of force and observe what happens.?

The researchers first used an atomic force microscope to bring the integrin molecule together with the fibronectin, then separated the two. Instruments measured the pico-newton forces required to separate the molecules, and found that the duration of the bonds increased with the repetition of the contacts.?

The second technique, known as BFP, involved the use of a fibronetctin-bearing glass bead attached to a red blood cell aspirated by a micropipette. Integrin expressed on a micropipette-aspirated cell was pressed into the bead, then pulled away over repeated cycles. Lifetime measurement confirmed that repeated pulling increased the longevity of the bonds.

Following this study the researchers hope to determine whether or not the cyclic mechanical reinforcement they observed is a universal property of many cellular adhesion molecules. They also hope to explore how cells use this cyclic mechanical reinforcement to gain a better understanding of the abnormal cellular adhesion mechanisms that occur in many diseases.

Professor Humphries says: ?The findings of the paper have deep implications for our understanding of force-regulated signaling. There is abundant biological evidence for profound effects of extracellular tensility and elasticity in controlling processes such as cancer cell proliferation and stem cell differentiation, but the mechanisms whereby this information is transduced across the outer cell membrane are unclear.?

The research, done by groups at the Georgia Institute of Technology and The University of Manchester in the United Kingdom, was supported by the National Institutes of Health (NIH) and the Wellcome Trust.
