CERN scientists explain what would happen if you put your hand in the LHC's beam (video)

CERN scientists explain what would happen if you put your hand in the LHC's beam (video)

Sure, concerns about the Large Hadron Collider creating a world-destroying black hole may have been more or less put to rest, but there's still plenty of pressing questions that remain unanswered. Like, what would happen if you put your hand in the beam? The folks from Sixty Symbols recently asked some physicists that very question and got some rather puzzled responses, so they went straight to CERN itself to get a definitive answer. You can see that in full after the break, but the short version is that it's something like the force of a moving aircraft carrier concentrated down to a laser-like one-millimeter-wide beam (accompanied by a wider beam of particles that would irradiate your entire body). Bad news. As they're quick to point out, though, actually getting anywhere near the beam is virtually impossible.

Kate Upton "Cat Daddy" Dance Video: Banned By YouTube?


The instantly infamous video of Kate Upton's "Cat Daddy" dance has reportedly been banned on YouTube, even though she's not even naked.

Sports Illustrated's 2012 swimsuit issue cover girl was asked to show off her dance moves on camera by Terry Richardson, and it was risque.

Risque enough to be pulled off YouTube, according to Fox News.

Upton was demonstrating how to do the "Cat Daddy," a dance created for the down and dirty hip-hop track of the same name by The Rej3ctz.

The moves saw her gyrating suggestively in a microscopic bikini and ending her teasing demonstration with “That's it, that's all you guys need?”

We wouldn't object to a sequel, but pretty much. On a related note, these Kate Upton bikini photos by Richardson are cool. Check them out!

UPDATE: It looks like you can still find the clip on YouTube on Terry's official channel, as long as you sign in and turn off the adult filter.

Not that we checked.

Gov't might be given more leeway in Clemens trial

(AP) ? The judge in the Roger Clemens perjury trial may be on the verge of letting the government show the former pitcher's jury just how widespread steroids and human growth hormone were in the sport. It's a move Clemens' lawyers would like to avoid but may have brought on themselves.

U.S. District Judge Reggie Walton said Monday that if the Clemens defense team continues its attack on a 2008 congressional hearing in which Clemens is alleged to have lied, government prosecutors should be allowed to present a "larger picture" of why the hearing took place.

Walton asked the government to show him the kind of information it wants to present. A prosecutor gave a hint at the end of Monday's session ? with the jury out of the room ? dropping the names of admitted drug users among major league players, such as Chuck Knoblauch and Jose Canseco. The defense fears this could taint Clemens with guilt-by-association.

Prosecutors said it's a necessary rebuttal to questions raised by Clemens' lawyer about the motive for the hearing.

"They can't have their cake and eat it, too," prosecutor Steven Durham said. "This simply isn't fair."

Clemens is on trial for allegedly lying in a 2008 congressional deposition and hearing when he said he never used steroids or HGH.

Clemens' lawyer Rusty Hardin opened up the possibility of a wider trial into steroid use with his questioning of the government's first witness, Phil Barnett. He was majority staff director for the House Oversight and Government Reform Committee when that panel held the 2008 hearing. Barnett said the hearing was a legitimate use of congressional power because it could have led to legislation.

How, Hardin asked in an incredulous tone, could asking Clemens whether he ever discussed HGH with strength coach Brian McNamee possibly lead to legislation?

After the government objected, Walton said he'd allow that line of questioning, but cautioned Hardin that he was opening the door to the wider government case.

That was one of a barrage of no fewer than 16 objections from the government. Walton handled some of them quickly, but on others he either cleared the jury from the room, or put on a sound machine to block jurors from hearing, while he huddled with lawyers from both sides. During one of those breaks, two of the jurors could be seen with their eyes closed.

Prosecutors used Barnett to try to establish that Congress was within its bounds in holding the hearing two months after Clemens was named in a 2007 report to the Commissioner of Baseball on drug use in the sport. The government has maintained that it was important for Congress to learn whether the report was accurate, in part because of concerns about steroids and HGH as a public health issue.

Hardin complained that the congressional hearing was "nothing more than a show trial." Determining whether Clemens was telling the truth when he denied the report's claims, he said, "is not a legitimate role for Congress."

Hardin raised the issue of whether Clemens' testimony at the hearing was truly voluntary ? suggesting that Clemens might have been subpoenaed had he not agreed to appear. But Barnett wouldn't concede that the pitcher would have been subpoenaed had he declined the committee's invitation; he said such a move was not automatic.

With Barnett on the stand, the government played portions of Clemens' televised testimony at the February 2008 hearing as well as an audiotape of the deposition that preceded it.

"Let me be clear: I have never used steroids or HGH," Clemens said confidently in the videotape of the hearing.

Darwinian selection continues to influence human evolution

ScienceDaily (Apr. 30, 2012) ? New evidence proves humans are continuing to evolve and that significant natural and sexual selection is still taking place in our species in the modern world.

Despite advancements in medicine and technology, as well as an increased prevalence of monogamy, research reveals humans are continuing to evolve just like other species.

Scientists in an international collaboration, which includes the University of Sheffield, analysed church records of about 6,000 Finnish people born between 1760-1849 to determine whether the demographic, cultural and technological changes of the agricultural revolution affected natural and sexual selection in our species.

Project leader Dr Virpi Lummaa, of the University's Department of Animal and Plant Sciences, said: "We have shown advances have not challenged the fact that our species is still evolving, just like all the other species 'in the wild'. It is a common misunderstanding that evolution took place a long time ago, and that to understand ourselves we must look back to the hunter-gatherer days of humans."

Dr Lummaa added: "We have shown significant selection has been taking place in very recent populations, and likely still occurs, so humans continue to be affected by both natural and sexual selection. Although the specific pressures, the factors making some individuals able to survive better, or have better success at finding partners and produce more kids, have changed across time and differ in different populations."

As for most animal species, the authors found that men and women are not equal concerning Darwinian selection.

Principal investigator Dr Alexandre Courtiol, of the Wissenschftskolleg zu Berlin, added: "Characteristics increasing the mating success of men are likely to evolve faster than those increasing the mating success of women. This is because mating with more partners was shown to increase reproductive success more in men than in women. Surprisingly, however, selection affected wealthy and poor people in the society to the same extent."

The experts needed detailed information on large numbers of study subjects to be able to study selection over the entire life cycle of individuals: survival to adulthood, mate access, mating success, and fertility per mate.

Genealogy is very popular in Finland and the country has some of the best available data for such research thanks to detailed church records of births, deaths, marriages and wealth status which were kept for tax purposes. Movement in the country was also very limited until the 20th century.

"Studying evolution requires large sample sizes with individual-based data covering the entire lifespan of each born person," said Dr Lummaa. "We need unbiased datasets that report the life events for everyone born. Because natural and sexual selection acts differently on different classes of individuals and across the life cycle, we needed to study selection with respect to these characteristics in order to understand how our species evolves."
