When it comes to the threat of extinction, size matters

2017-09-18 06:00:00| LifeSciencesWorld

[NEWS] CORVALLIS, Ore. — Animals in the Goldilocks zone — neither too big, nor too small, but just the right size — face a lower risk of extinction than do those on both ends of the scale, according to an extensive global analysis. Reporting today in the Proceedings of the National Academy of Sciences, researchers who determined body masses for thousands of vertebrate animal species showed that the largest and smallest species face a greater risk of extinction than do m…

'Mysterious' ancient creature was definitely an animal, research confirms

2017-09-14 06:00:00| LifeSciencesWorld

[NEWS] 'Mysterious' ancient creature was definitely an animal, research confirms It lived well over 550 million years ago, is known only through fossils and has variously been described as looking a bit like a jellyfish, a worm, a fungus and lichen. But was the 'mysterious' Dickinsonia an animal, or was it something else? A new study by researchers at the universities of Oxford, Cambridge, Bristol, and the British Geological Survey provides strong proof that D…

Could interstellar ice provide the answer to birth of DNA?

2017-09-14 06:00:00| LifeSciencesWorld

[NEWS] Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA. They found that organic compounds, called amino nitriles, the molecular precursors to amino acids, were able to use molecules present in interstellar ice to trigger the formation of the backbone molecule, 2-deoxy-D-ribose, of DNA. It has long been assumed that amino acids were present on earth before DNA…
