Some 9,000 years ago, residents of one of the world's first large farming communities were also among the first humans to experience some of the perils of modern urban living. Scientists studying the ancient ruins of Çatalhöyük, in modern Turkey, found that its inhabitants — 3,500 to 8,000 people at its peak — experienced overcrowding, infectious diseases, violence and environmental problems.
Dogs, more so than almost any other domesticated species, are desperate for human eye contact. When raised around people, they begin fighting for our attention when they're as young as four weeks old. It's hard for most people to resist a petulant flash of puppy-dog eyes—and according to a new study, that pull on the heartstrings might be exactly why dogs can give us those looks at all. A paper p

Doom Guy Finally, the HD remake we've all been waiting for: a series of neural nets took the classic pixelated mug of the space marine from seminal 1993 first-person shooter "Doom" and churned out an almost photorealistic portrait. The face, which looks sort of like a beefier Nathan Fillion, was posted to Reddit on Sunday. And while the resulting thread reveals that the process wasn't as straight

Study finds animals developed a facial muscle to wield emotional power over humans In a project that has all the makings of a Roald Dahl classic, scientists have hit on an answer to the mystery of how man's best friend got its puppy dog eyes. The sad, imploring expression held such power over humans during 33,000 years of canine domestication that the preference for dogs that could pull off the l
Scheduled Sleep Yet another Tesla driver has been caught on camera asleep behind the wheel — and this time, it clearly wasn't an accident. On Friday, Los Angeles' NBC4 reported that a driver spotted a man "fully sleeping" in his Tesla while the car's Autopilot system drove it for 30 miles down the busy 405 Freeway. A sleeping Tesla driver isn't as uncommon of a sight as it should be. But while pa

The formation of air bubbles in a liquid appears very similar to its inverse process, the formation of liquid droplets from, say, a dripping water faucet. But the physics involved is actually quite different, and while those water droplets are uniform in their size and spacing, bubble formation is typically a much more random process.
Some 9,000 years ago, residents of one of the world's first large farming communities were also among the first humans to experience some of the perils of modern urban living.
Since it debuted Friday, Taylor Swift's "You Need to Calm Down" has bounced around in my head for exactly the reason a pop song should: the way it sounds. I like that the beat's something a great beast might march to, slowly from one side to another, rumbling with each footfall. I like that the "oh-oh" swell of the chorus takes yummy harmonies, typically the key side dish in pop, and makes them t

Michelle Thaller's "absolute favorite fact in the universe" is that we are made of dead stars. The Big Bang, when it went off, produced basically three elements: hydrogen, helium, and lithium. Every atom more complex had to be formed inside a star. Over time, stars such as the sun produce things like carbon and oxygen. They don't really get much more far off the periodic table than that. If you w

The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to Dmitri Mendeleev and Lothar Meyer and the approaches of other chemists to organize the elements, involve different forms of representation of a hidden structure of the chemical elements. This is the conclusion reached by researchers at the Max

Dust is a critical component in the Martian atmosphere. It influences the atmosphere's circulation by heating or cooling it and is in turn redistributed around the planet by atmospheric winds. In this dust cycle, dust storms play a particularly important role. Storms are traditionally classified into local, regional and planet-encircling dust storms, with small, local storms occurring throughout t
Should journals always take authors at their word?
