Police kill armed eighth-grader in Texas school

By CHRIS SHERMAN, Associated Press
8:40 a.m., Jan. 4, 2012

? Police shot and killed an armed eighth-grader in his South Texas middle school hallway on Wednesday.

Brownsville police Detective J.J. Trevino said police received a call at about 8 a.m. that there was someone with a weapon at Cummings Middle School. Police found the 15-year-old student with a handgun in a hallway and shot him, Trevino said.

Cameron County Justice of the Peace Kip V. Johnson Hodge told The Brownsville Herald the student died.

Trevino said the school was immediately placed on lockdown, and that no one else was injured.

A school administrator apparently noticed the student carrying the gun and called Brownsville and school district police, Trevino said. He said investigators hadn't determined whether the student fired any shots, and he said he had no information on why the student might have had the gun on him.

"It's still under investigation, as far as how he came about to bringing the weapon or if he encountered anybody or anything else," Trevino said.

A school district spokeswoman didn't immediately respond to phone messages from The Associated Press, and calls to the school rang unanswered.

Brownsville is 280 miles south of San Antonio on the southern tip of Texas.

Video: Magnetically-levitated flies offer clues to future of life in space

Wednesday, January 4, 2012

Using powerful magnets to levitate fruit flies can provide vital clues to how biological organisms are affected by weightless conditions in space, researchers at The University of Nottingham say.

The team of scientists has shown that simulating weightlessness in fruit flies here on earth with the use of magnets causes the flies to walk more quickly ? the same effect observed during similar experiments on the International Space Station.

Dr Richard Hill, an EPSRC research fellow in the University's School of Physics and Astronomy, is one of the researchers involved in the study, which is published in the latest edition of the Royal Society journal Interface.

He said: "It is unfeasible to apply this technique to investigating the effects of weightlessness on a human being directly: no magnet exists that can do this. However, by studying the effects on 'model' organisms such as the fruit fly, we can hope to obtain information about the effects of weightlessness on particular biological mechanisms.

"It's also important to remember that, in our future endeavours to explore space, setting up permanent bases on our Moon, or Mars for example, or other planets, it will be crucial to understand the effects of weightlessness on all living organisms: our long-term survival will of course require us to take with us many different biological organisms."

The magnetic materials that we are most familiar with are ferromagnetic materials such as iron, which are strongly attracted to magnetic fields. However, most biological materials are affected by a different type of magnetism called diamagnetism, in which objects are weakly repelled from magnetic fields.

The team of scientists from Nottingham's Schools of Physics and Astronomy and Biology used the university's powerful superconducting magnet to produce a very strong magnetic field of around 16 Tesla ? approximately 350,000 times stronger than the strength of the Earth's field.

Inside the superconducting solenoid magnet, the diamagnetic repulsive force on the flies can be large enough to just balance the force of gravity so that they levitate with no support. This effect was first demonstrated by Nobel Prize-winning physicist Andre Geim and colleagues at the University of Nijmegen in 1997 when they used the same technique to levitate a live frog.

Dr Hill added: "Crucially, as far as living organisms are concerned, the levitation force balances the force of gravity right down to the molecular level. This means we can compare the levitation force, which balances the force of gravity in our magnet, with the centrifugal force that balances the force of gravity on an astronaut in orbit around the Earth.

"In orbit, aboard the international space station for example, gravity is still present, but because an orbiting body is effectively in 'free-fall', the centrifugal force on the astronauts (because they're going around the planet so quickly), is large enough to balance out the force of gravity. Here, we're using the diamagnetic force to balance gravity instead of centrifugal force."

The scientists need to be careful when using a strong magnetic field as it can have other effects on living organisms. However, they controlled for these effects by examining how the flies behaved in different parts of the magnet: at the centre of their solenoid magnet, there is a strong magnetic field but no diamagnetic force so the flies experienced normal gravity. By comparing how flies in the centre of the magnet behaved with flies outside the magnet, they could isolate the different effects of the strong magnetic field.

Dr Hill said: "What we showed was that the flies in the magnet behaved in the same way that they behave in space. They walk more quickly. Why they do this, we really don't know yet. It may be because the flies just find moving around in weightlessness easier on their joints and muscles, or it could be that it's some kind of response to their confusion about which way is up and down when gravity is absent."

Diamagnetic levitation doesn't balance gravity as perfectly as 'real' weightlessness does in space, but diamagnetic levitation can be used to see which experiments are suitable and interesting to perform in space before spending money on a space launch.

The advantage of doing these experiments on the ground is that it's a lot cheaper and much easier, and scientists do not need to worry about the effects of high g-forces endured when launching the flies into space on a rocket. It's also very easy to do the comparison between flies in weightlessness and flies in ordinary gravity: the scientists set up the same experiment in different positions in the magnet and run the experiments simultaneously. By moving the flies to different positions in the magnetic field, they can simulate gravities between zero-g and 2g (twice the Earth's gravity conditions), enabling them to simulate the gravity on the Moon or Mars.

The Bachelor Season Preview: Who IS SHE!?!?


The epic, four-minute trailer for the all-new season of The Bachelor that aired at the end of last night's season premiere has to be seen to be believed.

It has the feel of a big-budget film, not a reality show. Clearly, ABC ditched any pretense of love and ramped up the nudity, side plots and suspense.

More power to them. Sure, Ben is a real nice guy who probably does want to marry his final rose recipient, but it's ALL about the drama this year:

Straddling Ben, stripping buck naked in the ocean and openly taunting the competition, it seems safe to say Courtney's the "bad girl" this winter.

But who is the girl in red? Ben's ex? Another familiar face? See our page dedicated to The Bachelor spoilers to find out (what we think is) the answer.

And who is the woman in black? Is it the Black Widow herself?!

Cloaked in mystery (and ridiculousness), she boards a chopper on what we presume is the finale, only to do "a 180" about saying yes to Ben Flajnik?!

Share all your theories with us in the comments, and stay tuned all winter log as THG live blogs the scripted, contrived awesomeness of each episode.

(AP) ? Throwing elbows to the end, Republican candidates jostled over their conservative credentials and appealed to Iowa residents who were casting the first votes of the 2012 presidential race on Tuesday for a strong send-off into the long campaign season ahead.

Mitt Romney, a confident-but-cautious front-runner for the GOP nomination, looked past his Republican rivals to President Barack Obama in his final pitch to Iowa voters.

"This has been a failed presidency," he told voters in a Des Moines ballroom. "I will go to work to get Americans back to work."

With large numbers of likely caucus-goers still undecided or willing to change their minds, the outcome in Iowa was uncertain to the finish in a race that has elevated and then discarded a head-snapping assortment of front-runners.

The two who appeared most likely to challenge Romney for victory in Iowa were former Pennsylvania Sen. Rick Santorum and libertarian Rep. Ron Paul of Texas ? neither of whom is likely to present as serious a challenge to Romney over the long haul as would former House speaker Newt Gingrich or Texas Gov. Rick Perry.

"It might come down to the speeches at the caucuses," said Phil Ubben, of Sioux City. "I want to support someone who can go all the way and defeat the Democrats in November."

The candidates pinned their final hopes on such voters.

"I think anybody can come in first," Gingrich said. That was most likely wishful thinking for the former House speaker, who lost momentum after rising to the front of the GOP pack just weeks ago.

Training their sights on the pack leader, Gingrich, Santorum and other GOP rivals questioned Romney's conservative convictions and predicted Obama would, to use Gingrich's words, "tear him apart."

Santorum, enjoying a late surge in polls, offered himself as a reliable conservative and the only candidate who could solve "the intractable problem of exploding government." The 76-year-old Paul, looking to connect with young voters, dangled the name of pop singer Kelly Clarkson, who has endorsed him ? but admitted he didn't know much about her.

Romney answered persistent questions about whether he's a solid conservative by pointing to the 2008 race, casting himself as a "conservative alternative to John McCain" in the Republican primaries that year.

"I've got a record, and it's a conservative record," he said on Fox News Channel.

On Tuesday night, Republicans will gather in living rooms, high school gymnasiums and local libraries for caucuses that start the process of picking the GOP nominee. In each precinct caucus, voters will urge their friends and neighbors to support a preferred candidate. For all of the attention paid to the caucuses, they are essentially a nonbinding straw poll that awards no delegates. Republicans do that at county and district conventions later in the year.

Twenty-five delegates are at stake in Iowa, out of 1,144 needed to win the Republican nomination ? what Romney called "the whole enchilada."

Romney's campaign announced Tuesday it is going up with TV ads in Florida, which votes Jan. 31, sending a message he's got the money and organization to endure.

Obama isn't ceding the stage to the Republicans while they sort themselves out: The president, fresh off a 10-day Hawaiian vacation, made plans to host an evening live video teleconference with supporters in Iowa as the caucuses were under way.

And Mitch Stewart, a top Obama campaign aide, said in a morning email to the president's supporters: "Most of us will watch what happens on TV ? but, as you do, remember that the end of this story is up to you."

For all the talk of trust and electability, candidates in both parties know the economy is sure to be the central issue this election year: Obama was traveling to Cleveland on Wednesday for an event focused on the economy. Romney, for his part, said he's running to get the country back on track after Obama's mistakes.

Most polls in recent days have put Romney and Paul atop the GOP field in Iowa, with Santorum in third and gaining ground. More than a third of all potential caucus-goers said they could yet change their minds. Perry, Gingrich and Minnesota Rep. Michele Bachmann all trailed.

Romney faces the same challenge he did in 2008: winning over a conservative base that's uncomfortable with his moderate past. In 2008, socially conservative voters united behind former Arkansas Gov. Mike Huckabee, denying Romney a first-place finish and contributing to his eventual defeat.

Romney's 2012 rivals kept up their questions about his conservative convictions. Perry, speaking to Fox News on Tuesday, dismissed Romney as a "conservative of convenience." Bachmann offered herself as the "one true conservative."

Gingrich said Romney should "level with the American people" about his moderate political views. Asked on CBS if he was calling the former Massachusetts governor a liar, Gingrich said flatly, "Yes."

Emotions ? and rhetoric ? were hot in the campaign's final hours.

Santorum, blaming the Paul campaign for recorded phone calls questioning his policies on guns and abortion, told reporters at Fox News that "Ron Paul is disgusting."

Romney said he can handle any criticism his Republican rivals heap on him, calling it only a warm-up to whatever will come from Obama's camp. "My shoulders are wide," he insisted on Fox.

How many people turn out to vote will help drive the results. In 2008, more than 120,000 Republicans showed up, a record. Weather could be a factor this year. Iowa hasn't had much snow this winter, and there were clear but cold forecasts across the state.

After Tuesday's vote, Romney, Gingrich and Santorum planned to depart immediately for New Hampshire. Romney holds a commanding lead in polls there, and will be in a strong position to win even if he doesn't pull out a victory in Iowa. Paul plans to join his rivals in New Hampshire later in the week. The primary is Jan. 10.

Perry and Bachmann, both short-lived front-runners, don't plan to compete in New Hampshire, instead heading straight from Iowa to the first-in-the-South primary, set for Jan. 21 in South Carolina. Bachmann pronounced herself ready to move on: "This election is far from over," she said. "This is the opening chapter. Tonight is the first vote. We've got a long road to go."

Perry tried to buck up disheartened supporters by comparing caucus day to historic military campaigns of yore: "This is Concord," he said. "This is Omaha Beach."

Romney also plans to visit South Carolina this week, with campaign stops Thursday and Friday.
