Scientists from seven countries, including Austria, the Netherlands and five key Arctic states (Russia, USA, Canada, Norway, and Sweden) - participants of the International Arctic Science Committee (IASC) published an article on the study of the so-called sources of black carbon emissions in the Arctic in the Science Advances. Black carbon (BC) aerosols are formed under incomplete fuel combustion in diesel engines, as well as during wildfires, wood burning in wood-burning stoves, brick-kilns, and so on. The main component of black carbon is soot which falls on the surface of snow and ice thus decreasing the ability of the originally white surface to reflect incoming solar radiation. In turn, this amplifies the melting of snow and ice cover, and therefore, can accelerate global warming. A co-author of the study, head of TPU International Research Laboratory for Arctic Seas Carbon, Associate Member of RAS, Professor Igor Semiletov says: 'The article called Source apportionment of … [Read more...] about Scientists Discovered Where Black Carbon Comes From in the Arctic in Winter and Summer
Researchers have established a correlation between depression and a group of neurotransmitter-producing bacteria found in the human gut. The research team from the U.S. Department of Energy's (DOE) Argonne National Laboratory, Northeastern University and elsewhere made the connection by first isolating the KLE1738, a bacterium that has a surprising dependency upon a brain chemical called gamma-aminobutyric acid (GABA). "The association of microbial GABAmetabolism with mental health is highly compelling," said Jack Gilbert, group leader for microbial ecology at Argonne who also holds new faculty appointments at the University of California, San Diego, in the Department of Pediatrics and at Scripps Institution of Oceanography. "The general ability of the microbiome to produce and/or consume GABA has not been as broadly described before, and a bacterium dependent on GABAhas never been reported." Gilbert and 18 co-authors published their findings on December 10, 2018, in Nature … [Read more...] about Newly Isolated Human Gut Bacterium Reveals Possible Connection to Depression
Here's another milestone on the road toward Star Wars: Episode 9. Filming on the final movie in the saga has wrapped, director J.J. Abrams announced Friday. "There is no adequate way to thank this truly magical crew and cast," Abrams tweeted, while sharing a photo of cast members hugging.The tweet only sparked fan interest in the eventual announcement of the film's title. "Now we just need that title reveal along with a few trailers to get us all psyched for December," wrote Samuel James.Actor Anthony Daniels, who plays C-3PO, has been teasing hints about the title, and star Mark Hamill, who plays Luke Skywalker, has also joked about it. Personally, I'm still rooting for Star Wars: A New Order, as a throwback to the first Star Wars film, later dubbed Star Wars: A New Hope.Episode 9 opens worldwide on Dec. 20, 2019. … [Read more...] about Star Wars: Episode 9 filming wraps, but where’s that title?
Have you seen this man? No, he’s not a missing person. Or at least not in any conventional sense. The face in question was generated by an artificial intelligence on the new website ThisPersonDoesNotExist.com. While it’s been clear for quite some time that modern A.I. is getting pretty darn good at generating accurate human faces, it’s a reminder of just how far we’ve come from the uncanny valley effect seen in movies like 2004’s Polar Express. The site is the work of Philip Wang, a software engineer at Uber. Wang says that the idea for the project started in 2014 with a conversation with Ian Goodfellow, a deep -earning research scientist, currently at Google Brain, who introduced the concept of a generative adversarial network (GAN). They discussed the notion of pitting two neural networks against one another: One designed to generate new images, and the other to figure out which images are computer-generated and which are real. Over time, the … [Read more...] about A.I.-powered website creates freakishly lifelike faces of people who don’t exist
