275x250.jpg Boffins from Russia and South Korea have signed an agreement which will see them attempt to clone a woolly mammoth.

That's right the researchers hope to go all Jurassic Park and  recreate a creature which last walked the earth 10,000 years ago.

North-Eastern Federal University of the Sakha Republic and Hwang Woo-Suk of South Korea’s Sooam Biotech Research Foundation will work on the project.

They will start by working with thawed woolly mammoth remains which were recovered after global warming thawed Siberia’s permafrost.

If they are able to restore mammoth cells (after suitable science-pokerey) the eggs will be implanted into the womb of a live elephant.

275x250.jpg There's something reassuring about seeing a boffin wearing a white lab coat isn't there?

Well apparently the feeling is justified, because researcher have discovered wearing a lab coat makes people concentrate on their work and make fewer errors.

The boffins from Northwestern University -- who we assume were wearing their own lab coats -- tested their theory with 58 undergraduates.

The students (half wearing lab coats) were asked to name the colour of a word flashed on a computer screen, while ignoring the word itself.

It was found that those wearing the classic white lab coat made half as many errors.

275x250.jpg Boffins have proposed creating the world's most accurate clock -- a device tied to the orbiting of a neutron around an atomic nucleus.

Researchers from the University of New South Wales say the proposed clock would neither gains nor loses 1/20th of a second in 14 billion years, the age of the Universe.

Because the neutron is held so tightly to the nucleus, its oscillation rate is almost completely unaffected by any external perturbations, unlike those of an atomic clock’s electrons, which are much more loosely bound.

"This is nearly 100 times more accurate than the best atomic clocks we have now," says one of the researchers, Scientia Professor Victor Flambaum, of the UNSW School of Physics.

"It would allow scientists to test fundamental physical theories at unprecedented levels of precision and provide an unmatched tool for applied physics research."

275x250.jpg School children in Birmingham have burst their way into the record books and made science history by taking part in the World’s Biggest Practical Science Lesson.

More than 250 pupils from Bishop Challoner Catholic College took part in the science lesson led by world bubble mastermind, Samsam Bubbleman, and hoped to master the science behind bubble-blowing.

Equipped with bubble swords, and under the watchful eye of an official Guinness World Records adjudicator, they were blown-away with a lesson in gravity and light refraction, producing thousands of gigantic soap spheres and bouncing bubbles.

Samsam said: "Today has been un-bubble-ievable! (oh yes he did!) I can’t think of a better way to celebrate The Big Bang Fair coming to Birmingham than blowing our way into the books of Guinness World Records.

275x250.jpg Men are more attracted to women who wear red coloured clothing… because they think they'll be more interested in having sex, it has been found.

Researchers at the University of Rochester say that in many non-human primate species, female red displays are a signal of sexual receptivity and this signal attracts male conspecifics.

As such they decided to look at whether the same in humans and conducted experiments in which man were asked to rate the attractiveness of women and gauge, on a scale of 1 to 9, if they was "interested in sex."

It was found that not only did men perceive women in red as sexually receptive, but that they  also perceive sexually receptive women as attractive… like we needed a scientific study to tell us that.
