The study, released on March 4 by researchers at the Harbin Institute of Technology in Shenzhen and Johns Hopkins University, used Chinese CDC data on about 1,200 people exposed to Covid-19 patients to determine if the virus infected different age groups at different rates.
Microsoft Edge received the lowest privacy rating in a recently published study that compared the user information collected by major browsers.Edge also sends the hardware UUID of the device to Microsoft and Yandex similarly transmits a hashed hardware identifier to back end servers.
Dolphin numbers in the Indian Ocean may have dropped by more than 80 percent in recent decades, with an estimated 4 million small cetaceans caught as “by-catch” in commercial tuna-fishing nets since 1950, according to a study.
There’s been understandable blowback from the hand-dryer industry, which notes that certain studies pegging hand dryers as disease vectors were carried out by researchers who had worked as consultants for paper-towel manufacturers.
At the same time, the report warns that there’s no guarantee that the efficiency drive will continue in the face of data-hungry new technologies such as artificial intelligence and 5G.Some previous analyses have suggested data center energy use has doubled, or more, over the last decade.
While conducting a study on body decomposition, in separate incidents, forensic researchers unintentionally captured footage of two feral cats feasting on human corpses.
But it’s not all about instinct: a paper published in PNAS this week suggests that parents can be trained to improve their parentese and that this training gives their babies’ language a boost.
In 2017, researchers from the Iceland Deep Drilling Project, run by the Icelandic government and a consortium of national energy companies, reported they had reached supercritical fluids 3 miles beneath the surface.
The license to operate the two reactors at the Philippsburg nuclear facility expired at midnight after 35 years of providing carbon-free power to Germans living along the country’s southwestern border.
That’s the conclusion of a new study by a group of British researchers who analyzed rates of change for popular songs, English literature, scientific papers, and car design.
Yet another study found feral cats are highly attracted to areas that burned recently and tend to avoid ones three months or older, perhaps because vegetation has begun to grow back by that time, or they’ve simply obliterated the prey species there.
Google researchers made headlines early this month for a study that claimed their artificial intelligence system could outperform human experts at finding breast cancers on mammograms.Machine-enabled healthcare may bring us many benefits in the years to come, but those will be contingent on the ways in which it’s used.
Kristin Laidre, an animal ecologist at the University of Washington and a coauthor, says the melting summer sea ice is causing trouble for big mammals: polar bears, walruses, and seals.
The p refers to the p-value, a ridiculously complicated statistical entity that’s essentially a measure of how surprising the results of a study would be if the effect you’re looking for wasn’t there.
Previously, planetary scientists had assumed that Saturn’s rings were as old as the solar system itself—about 4.5 billion years old.“Every new exciting result gets challenged,” said Burkhard Militzer, a planetary scientist at the University of California, Berkeley and a co-author of the Science paper.
Every weekday, WIRED publishes a new cartoon about the worlds of science and technology.And if that's still not enough, you can find all of WIRED's cartoons in one place, right here .
Indeed, the group says that if their mission is selected by NASA it could fly as soon as 2030.“This is humanity’s first explicit step into interstellar space,” says Pontus Brandt, a physicist at the Johns Hopkins Applied Physics Laboratory who is working on the interstellar probe study.
Lewis outfitted the participants with an EEG cap so she could look at the electrical currents flowing through their brains.“It’s a fantastic paper,” says Maiken Nedergaard, a neuroscientist at the University of Rochester who led the 2013 study that first described how sleep can clear out toxins in mice.
That's how long scientists allowed frozen sperm to be in microgravity as part of a study on what human reproduction would look like in space.If you were buying a new car, wouldn't you want to have the best features, safety, and value for your money?
On the last point: Some engineers are trying to build more fun, friendly, and maybe even safer crosswalks, but the federal government—the same one that put out those safety stats!—is not yet convinced that kind of street design works.
The company declined to say whether there have been shifts in tipping since mid-September 2017.The paper relies on detailed data about drivers, riders, and the rides themselves, including length, pickup time, and how many quick accelerations, hard brakes, and speeding stretches occurred during the trip.
The authors say the quantity and popularity of alternative (mostly right-wing) political media on YouTube is driven by both supply and demand.“We believe that the novel and disturbing fact of people consuming white nationalist video media was not caused by the supply of this media ‘radicalizing’ an otherwise moderate audience,” they write.
Fu and her colleague and spouse Louis Ptáček, both at the University of California, San Francisco, had just identified a gene mutation that significantly decreased how many hours someone needs to sleep .
