Twitter, Reddit, and Internet Association filed an amicus brief late yesterday in support of a lawsuit filed last year by the Knight First Amendment Institute at Columbia University, the Brennan Center for Justice, and Simpson Thacher & Bartlett LLP on behalf of plaintiffs Doc Society and International Documentary Association, challenging rules that require nearly all visa applicants to register their social media handles with the U.S. government and connected policies permitting the retenti...

Vegetarianism and veganism are growing in popularity. In this Spotlight, we ask why these dietary choices can ignite rage in some meat eaters. The answer, it seems, is complex.

An important lesson of the #MeToo movement has been that perpetrators of sexual assault include people who have been previously dismissed as potential predators — that sexual assaults can be and are committed by respected members of elite communities, including beloved comedians, Hollywood power players and prominent, well-paid journalists. No one, by virtue of their social or economic status, should be written off as incapable of assault.

A video that surfaced in Kyiv showing newborns who can't be reunited with their adoptive parents is causing outrage. DW investigates the contentious, but lucrative practice of surrogacy during the coronavirus pandemic.

Scientists say more than 50 billion years of cumulative evolutionary history could be lost as humans push wildlife to the brink. "Weird and wonderful" animals unlike anything else on Earth are sliding silently toward extinction, they say. And regions home to the greatest amounts of unique biodiversity are facing unprecedented human pressures. They include the Caribbean, Western Ghats of India and large parts of Southeast Asia.

Over 100 years ago Charles Spearman made two monumental discoveries about human intelligence. First, a general factor of intelligence (g) exists: people who score high on one test of intelligence also tend to score high on other tests of intelligence. Second, Spearman found that the g-factor conforms to the principle of the "indifference of the indicator": It doesn't matter what test of intelligence you administer; as long as the intelligence test is sufficiently cognitively compl...

Two unrelated studies recently raised the same possibility: the laws of physics might not apply everywhere, which, if true, would upend an idea underpinning centuries of science.

SURVEILLANCE FIRMS around the world are licking their lips at a once-in-a-lifetime opportunity to cash in on the coronavirus by repositioning one of their most invasive products: the tracking bracelet. Body monitors are associated with criminality and guilt in the popular imagination, the accessories of Wall Street crooks under house arrest and menace-to-society parolees.

Why are we here? What is our purpose? Why are U.S. service members not allowed to grow beards? It is questions such as these, which tug at mankind’s innermost curiosities, that religions have endeavored to answer since the beginning of time. For some of those faiths, proper observance necessitates the growth of facial hair.

When Jenny Marr turned 34 she decided it was time to start a family. The Dallas, Texas woman and her husband Chris wanted one child to complete their family of four - their third family member being their dog, Zeke. According to the Washington Post, Marr took a positive pregnancy test on October 6 and from there the couple counted down to the moment they'd be able to hear their baby's heart beat for the first time.

Slim Shady’s second major-label album was many things: a masterclass in rapping, an occasionally uncomfortable listen, a vessel for many tortured by angst, and, briefly, a national crisis. This is how he created a million others just like him.

Li Jingzhi quit her job to search China for her son, Mao Yin, who went missing in 1988.

In this week’s release of watchOS 6.2.5 developer beta 5, Apple has snuck in a couple new watch faces — just in time for the worldwide (at home) Pride celebrations of the year. The new watch faces come in the form of customization options for the existing Pride Digital, Pride Analog, and Gradient faces. There …

Our sun has gone into lockdown, which could cause freezing weather, earthquakes and famine, scientists say. The sun is currently in a period of “solar minimum,” meaning activity on its surface has fallen dramatically. Experts believe we are about to enter the deepest period of sunshine “recession” ever recorded as sunspots have virtually disappeared.

In the week of 12 to 18 April, the top ten search terms on Amazon.com were: toilet paper, face mask, hand sanitizer, paper towels, lysol spray, clorox wipes, mask, lysol, masks for germ protection, and n95 mask.

Taking the next step in the IndyCar physical challenge involves trying to breathe in the corners, as Franchitti explains. "Remember, you can't breathe above a certain number of G forces, so you get into the corner and brace yourself like a fighter pilot does when he's making a hard turn," he said before describing an oxygen-deprived lap in detail.

The discrepancy between how fast the universe seems to be expanding and how fast we expect it to expand is one of cosmology’s most stubbornly persistent anomalies. Cosmologists base their expectation of the expansion rate—a rate known as the Hubble constant—on measurements of radiation emitted shortly after the Big Bang. This radiation reveals the precise ingredients of the early universe. Cosmologists plug the ingredients into their model of cosmic evolution and run the model forward to s...

The coronavirus pandemic has forced the cancellation of the 40th annual Ernest Hemingway Look-Alike Contest in Key West, Florida. The three-night competition, which had been scheduled for July 23-25, typically attracts more than 100 burly, bearded contestants from the US and further afield to Sloppy Joe’s Bar, but organisers were concerned about hosting packed crowds.

The Raspberry Pi Foundation has announced a new camera board that should dramatically improve the photographic capabilities available to the popular DIY computer’s enthusiasts and hobbyists. It’s called the High Quality Camera, and it’s built around a 12.3-megapixel backside-illuminated Sony IMX477 sensor with 1.55-micron pixels.

Consumes the same energy as biological neurons. A chip 100 times smaller than the diameter of a human hair is capable of replicating the activity of a biological brain with the same neurological voltage. Thirty years ago, researchers at the University of Massachusetts at Amherst discovered a proteobacteria called the Geobacter in the Potomac River that could produce nanowires of electrically conductive proteins.
