SCIENCE: AI Sucks at Making Adorable Cat Photos

Artificial intelligence (AI) recently tried to generate cat photos from scratch, and the results were cat-astrophic. This particular neural network (a type of AI modeled after the workings of the human brain) can produce astonishingly realistic original photos of human faces. In fact, the images of these made-up people were nearly impossible for human viewers to distinguish from photos of real people, programmers of the AI reported in a study that was posted December 2018 to the preprint journal arXiv. Felines, however, proved to be another story. The same algorithm that generated flawless human faces created cats with misshapen heads; … Read more

SCIENCE: When Earth Was a Snowball

It’s difficult to imagine now, but at certain points in Earth’s history, ice covered the entire planet. This frozen Earth, nicknamed snowball Earth, was a setting “so severe, that the Earth’s entire surface, from pole to pole, including the oceans, completely froze over,” said Melissa Hage, an environmental scientist and assistant professor at Oxford College of Emory University in Georgia. In 1840, Louis Agassiz, a Swiss natural scientist, was among the first to acknowledge and provide evidence that Earth had gone through ice ages, according to the University of California Museum of Paleontology. Joseph Kirschvink, an American geologist, later coined … Read more

SPACE: Are Black Holes the Lighthouses of the Universe?

Stunning new images show how black holes produce tremendously bright jets millions of light-years long that can be seen across vast cosmic distances. The images were produced by a computer simulation and could help resolve an enduring mystery about how the jets form, the researchers behind the images said. Despite their moniker, black holes aren’t always black. As a black hole consumes an object, gas and dust spins around the maw of the gravitational behemoth, and friction can heat the material on the edges to searing temperatures. This violent process creates lighthouse-like beams of charged particles that travel outward at … Read more

SCIENCE: How The World Ends Version Three

A new study published in the journal Biological Conservation described as “a comprehensive review of 73 historical reports of insect declines from across the globe” makes a grim prediction: “dramatic rates of decline that may lead to the extinction of 40% of the world’s insect species over the next few decades.” Insects could completely disappear from the Earth within 100 years if they continue to decline at current rates, The Guardian notes: “More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, … Read more

SCIENCE: We Can Now Rewrite Rat Memories

When Ivan Pavlov’s dog heard the ding of a bell, the pup started salivating in anticipation of his dinner. When professor Mary Torregrossa’s rats heard a similar tone, they craved cocaine. At least, some of them did — before Torregrossa and her colleagues rewrote their memories. Torregrossa studies the psychology of drug addiction and relapses at the University of Pittsburgh School of Medicine (where she is also an associate professor of psychiatry). In a new study published Jan. 22 in the journal Cell Reports, Torregrossa and two of her colleagues set up a Pavlovian experiment in which a group of … Read more

AI Can Now Read Your Mind (Sort Of)

Neuroscientists are teaching computers to read words straight out of people’s brains. Kelly Servick, writing for Science, reported this week on three papers posted to the preprint server bioRxiv in which three different teams of researchers demonstrated that they could decode speech from recordings of neurons firing. In each study, electrodes placed directly on the brain recorded neural activity while brain-surgery patients listened to speech or read words out loud. Then, researchers tried to figure out what the patients were hearing or saying. In each case, researchers were able to convert the brain’s electrical activity into at least somewhat-intelligible sound … Read more

2018’s Ten Weirdest Science Stories – Live Science

What were the top 10 strangest science stories of the past year? It wasn’t easy to choose just 10 — 2018 was pretty darn strange. However, writers at Live Science and at our sister site Space.com managed to put together a list of our favorites; from a space-bound Tesla to an unusual (and uncomfortable) confrontation between a seal and an eel. Ne-crow-philia? Crows can do some pretty amazing things. They use tools. They can solve puzzles. They also, sometimes, have sex with their dead. Scientists placed a dead crow on the ground and watched how other crows reacted. Some mounted … Read more

Are Black Holes Portals to the Future? – Live Science

Black holes are among the most mysterious places in the universe; locations where the very fabric of space and time are warped so badly that not even light can escape from them. According to Einstein’s theory of general relativity, at their center lies a singularity, a place where the mass of many stars is crushed into a volume with exactly zero size. However, two recent physics papers, published on Dec.10 in the journals Physical Review Letters and Physical Review D, respectively, may make scientists reconsider what we think we know about black holes. Black holes might not last forever, and … Read more

Greenland May Soon Be Green Again – Live Science

Greenland - Sarah Das/Woods Hole Oceanographic Institution

Greenland is melting faster today than it has at any time in the last 350 years, and probably much longer, new research finds. Surface melt from the icy island has increased 50 percent in the last 20 years compared with the early 1800s, before the industrial era, researchers report today (Dec. 5) in the journal Nature. The runoff alone is now contributing about a millimeter to the global average sea level per year, said study co-author Sarah Das, a glaciologist at Woods Hole Oceanographic Institution. “Climate change has hit Greenland very hard recently, and the ice sheet is responding quickly,” … Read more

SPACE: Scientists Propose Tunnelbot to Explore Europa

tunnelbot

A group of scientists wants to send a nuclear-powered “tunnelbot” to Europa to blaze a path through the Jovian moon’s thick shell of ice and search for life. Europa, the fourth largest of Jupiter’s 53 moons, is one of the best candidates in our solar system for hosting alien life. Researchers believe that its icy crust hides a liquid water ocean and that vents through that crust might deliver the necessary heat and chemical ingredients for life into that ocean.To peek beneath that thick veil of ice, researchers on the NASA Glenn Research COMPASS team (a group of scientists and … Read more
