Giant Cattle To Be Bred Back From Extinction

Posted by: Audiegrl

Aurochs were immortalized in prehistoric cave paintings and admired for their brute strength and “elephantine” size by Julius Caesar

Telegraph.co.uk/Nick Squires~~But despite their having gone the way of the dodo and the woolly mammoth, there are plans to bring the giant animals back to life.

The huge cattle with sweeping horns which once roamed the forests of Europe have not been seen for nearly 400 years.

Now Italian scientists are hoping to use genetic expertise and selective breeding of modern-day wild cattle to recreate the fearsome beasts which weighed around 2,200lb and stood 6.5 feet at the shoulder.

Breeds of large cattle which most closely resemble Bos primigenius, such as Highland cattle and the white Maremma breed from Italy, are being bred with each other in a technique known as “back-breeding“.

At the same time, scientists say they have for the first time created a map of the auroch’s genome, so that they know precisely what type of animal they are trying to replicate.

We were able to analyse auroch DNA from preserved bone material and create a rough map of its genome that should allow us to breed animals nearly identical to aurochs,” said team leader Donato Matassino, head of the Consortium for Experimental Biotechnology in Benevento, in the southern Campania region.

We’ve already made our first round of crosses between three breeds native to Britain, Spain and Italy. Now we just have to wait and see how the calves turn out.

Strong Start For Lopez Tonight

Posted by Audiegrl

georgeLopezTBSWebLatina Magazine/Lee Hernandez—By George, I think he’s got it. Comedian George Lopez’s new late-night talk show, Lopez Tonight, premiered to a very healthy 3.1 million viewers Monday night on three Turner Networks: TBS, TNT and TruTV, says Variety.

1.7 million of those combined total viewers watched the show on TBS—a good thing for the show since that’s where it will air weekly at 11 p.m. But more importantly, the debut—which featured guests Eva Longoria Parker, Kobe Bryant and Carlos Santana—performed solidly among adults (1 million viewers) in the key 18-49 demographic that advertisers love. “That’s higher than the current season averages (though not the premieres) of the adult demo draws for talk shows like CBS’ Late Late Show With Craig Ferguson, ABC’s Jimmy Kimmel Live and Comedy Central’s The Daily Show With Jon Stewart. If you use the combined three-net number, the show was sampled by more adult demo viewers than Conan O’Brien or David Letterman’s average,” writes The Hollywood Reporter’s James Hibberd.

In even more good news for Lopez Tonight, the show, which aired in place of TBS’s usual reruns of My Name is Earl drew 70% higher household ratings than Earl. “Viewers are ready for a change, and George Lopez is an exciting addition to late-night television,” said Steve Koonin, president of Turner Entertainment Networks. “We are extremely proud of the success of last night’s premiere of Lopez Tonight and are confident the show will continue to be a big late-night hit.”

Lopez Tonight‘ offers surprising DNA test to Larry David

larry-davidOrlando Sentinel—TBS’ “Lopez Tonight” is billing itself as the first late-night show to offer DNA testing of its guests.

The shows promises that its Thursday episode will be different: “Larry David (‘Curb Your Enthusiasm‘) will get the surprise of his life when his true ethnicity is revealed.”

And the show hosted by George Lopez made this questionable boast: “It’s sure to be as good as an episode of ‘Curb Your Enthusiasm.‘”

Spoiler Alert: On the show last night, Larry discovered that he is 63 percent European, and 37 percent Native American.

DNA tests on skull fragment cast doubt on Adolf Hitler suicide story

Bone with bullet hole found by Russians in 1946 came from an unknown woman, not the German monster

Guardian.co.uk/Uki Goñi—In countless biographies of Adolf Hitler the story of his final hours is recounted in the traditional version: committing suicide with Eva Braun, he took a cyanide pill and then shot himself on 30 April 1945, as the Russians bombarded Berlin.

Some historians expressed doubt that the Führer had shot himself, speculating that accounts of Hitler’s death had been embellished to present his suicide in a suitably heroic light. But a fragment of skull, complete with bullet hole, which was taken from the bunker by the Russians and displayed in Moscow in 2000, appeared to settle the argument.

Until now. In the wake of new revelations, the histories of Hitler’s death may need to be rewritten – and left open-ended. American researchers claim to have demonstrated that the skull fragment, secretly preserved for decades by Soviet intelligence, belonged to a woman under 40, whose identity is unknown. DNA analyses performed on the bone, now held by the Russian State Archive in Moscow, have been processed at the genetics lab of the University of Connecticut. The results, broadcast in the US by a History Channel documentary, MysteryQuest: Hitler’s Escape, astonished scientists.

According to Connecticut archaeologist and bone specialist Nick Bellantoni, it was clear from the outset that something was amiss. “The bone seemed very thin; male bone tends to be more robust,” he said. “And the sutures where the skull plates come together seemed to correspond to someone under 40.” In April 1945 Hitler turned 56.

Researchers Identify Genes Affecting Alzheimer’s Risk

Alzheimer's Stamp

Alzheimer's Stamp

By David Brown, Washington Post Staff Writer—Two European research teams have identified three genes that affect a person’s risk of developing Alzheimer’s disease, the most common cause of dementia in the elderly.

The new genes appear to have at least as big a role as four others discovered in the last 15 years that are known to play a role in Alzheimer’s.

“The message here is that genes are important in Alzheimer’s disease . . . and there may be multiple ways of reducing the risk that the genes produce,” said Julie Williams, a neuroscientist at Cardiff University in Wales who helped lead one of the teams.

All so-called “Alzheimer genes” have normal roles in brain physiology; they don’t exist solely to cause dementia. Instead, small variations in their DNA alter their function and, through processes only now being uncovered, increase or reduce a person’s risk of developing the disease.

Two of the genes described in the new research may be involved in determining the brain’s capacity to clear itself of toxic “amyloid” proteins that collect outside neurons, eventually poisoning them.

The most important previously known Alzheimer gene promoted overproduction of amyloid. The new findings suggest that at least two processes — production of amyloid and its removal — are involved in the disease.

At least 5 million Americans have Alzheimer’s disease. By one estimate, one in seven people aged 72 and older have dementia, with Alzheimer’s the most common form.
