NASA is running out of space suits — and it’s years away from having new ones ready

The state of NASA’s space suit supply looks bleak in a new report from the space agency’s auditor. NASA is still “years away” from having a new space suit ready for future deep-space missions, the report claims, even though the agency has invested close to $200 million on space suit development since 2007. Meanwhile, NASA seems to be running out of the space suits it does have for the astronauts on the ISS. Only a fraction of the original space suit supply for the station is fully functional right now, and NASA may risk not having enough space suits to last through the end of the ISS program, currently scheduled… Read More

Ancient human DNA found in Ice Age caves — even when bones were missing

Scientists found DNA from ancient humans in the soil of caves — even when there were no bones uncovered at the site. The research shows that, even when no fossils are around, sediments inside caves can tell us which early humans were present where and when. This information is key for understanding the evolution of our human ancestors. The study, published today in Science, describes a highly sensitive technique for analyzing ancient DNA. The technique was used to study sediment from seven caves in Europe and Russia, dating between about 14,000 and 550,000 years ago. Among countless genetic fragments, the researchers were able to detect the DNA of Neanderthals and… Read More

Scientists Can Now Pull the DNA of Ancient Humans Out of Cave Dirt

Around 45,000 years ago, in a Belgian cave, a Neanderthal died. As its body decayed, its cells split apart, spilling their contents onto the cave floor. Those remnants included the Neanderthal’s DNA, some of which stuck to minerals in the sediment. There, leashed to the very rock, the DNA persisted, long after its owner’s body had disappeared and its bones had been carted off by scavengers. And in 2015, a group of scientists scooped it up. Viviane Slon from the Max Planck Institute for Evolutionary Anthropology and her colleagues have now managed to extract and sequence the DNA of ancient animals from sediment that’s up to 240,000 years old. By… Read More

Facebook admits governments use it to manipulate public opinion, says it will fight fake ‘information operations’

SAN FRANCISCO — Facebook Inc acknowledged on Thursday that it has become a battleground for governments seeking to manipulate public opinion in other countries and outlined new measures it is taking to combat what it calls “information operations” that go well beyond the phenomenon known as fake news. In a report and summary of response plans on its website on Thursday, Facebook describes well-funded and subtle efforts by nations and other organizations to spread misleading information and falsehoods for geopolitical goals. These initiatives go much further than posting fake news stories to include amplification – essentially widening the circulation of posts through a variety of means – carried out by… Read More
