[:eu]Isotopic similarities seen in materials that formed Earth, moon[:]
[:eu]Most scientific models contend the Earth formed gradually by addition from an assortment of moon- to Mars-sized masses that had a vast array of isotopic characteristics. New research published Jan. 26 in Nature maintains the Earth, as well as the moon and certain meteorites, were formed from materials that were more similar, holding almost indistinguishable…

[:eu]Biologists breed life form with lab-made DNA. Don’t call it ‘Jurassic Park’.[:]
[:eu]Scientists led by the Scripps Research Institute in La Jolla, Calif., have added two extra, artificial letters to the ancient alphabet of A, C, G and T. And the E. coli living with this unusual six-letter, three-base-pair alphabet are, by the account published Monday in the Proceedings of the National Academy of the Sciences, capable…

[:eu]Dividing Droplets Could Explain Life’s Origin[:]
[:eu]Researchers have discovered that simple “chemically active” droplets grow to the size of cells and spontaneously divide, suggesting they might have evolved into the first living cells.[:]

[:eu]Graph Isomorphism Vanquished — Again[:]
[:eu]On January 4, László Babai, a professor at the University of Chicago, sent shock waves through the community by retracting a claim which, back in November 2015, researchers had hailed as the theoretical computer science advance of the decade. Then on January 9, Babai announced that he had fixed the flaw in his proof. And…

[:eu]Analysis of more than 50,000 genomes hints at new disease-causing genes[:]
[:eu]In the largest study of its kind, a research team has meshed extensive genome data on more than 50,000 people with their electronic health records and identified potential new disease-causing genes. The data further suggest that about one in 250 people may harbor a gene variant that puts them at risk for heart attacks and…

[:eu]Meet Chewie, the biggest Australopithecus on record[:]
[:eu]40 years later, researchers have found more hominin footprints at the world-famous site, called Laetoli. They comprise tracks from two more individuals, including those of a man who would have weighed 48 kilograms and stood 1.65 metres tall, larger than any other Australopithecus in the fossil record. Researchers have named him Chewie, after the 2-metre-tall…
