Car tires and brake pads produce harmful microplastics

There’s a big problem where the rubber meets the road: microplastics. Scientists analyzed more than 500 small particles pulled from the air around three busy German highways, and found that the vast majority — 89 percent — came from vehicle tires, brake systems and roads themselves. All together, these particles are classified by the researchers […]

By flying over atmospheric rivers, scientists aim to improve forecasts

The term “atmospheric river” may sound airy and ethereal, but these massive, fast-moving, drenching storms can hit as hard as a freight train. Since December, the U.S. West has been slammed with back-to-back-to-back atmospheric rivers, the most recent one deluging the state March 15 and another forecast to hit the state in the coming week. […]

Crime solvers embraced genetic genealogy

Every week, Ellen Greytak checks DNA profiles in a genealogy database. She’s not searching for long-lost relatives. She’s out to find family members of unknown assailants in rape and murder cases. Greytak is director of bioinformatics at Parabon NanoLabs in Reston, Va. Since May, the company has used genetic genealogy, a forensic technique for tracking […]

News of the first gene-edited babies ignited a firestorm

A Chinese scientist surprised the world in late November by claiming he had created the first gene-edited babies, who at the time of the announcement were a few weeks old. Scientists and ethicists quickly responded with outrage. In an interview with the Associated Press and in a video posted November 25, Jiankui He announced that […]

How the periodic table went from a sketch to an enduring masterpiece

Every field of science has its favorite anniversary. For physics, it’s Newton’s Principia of 1687, the book that introduced the laws of motion and gravity. Biology celebrates Darwin’s On the Origin of Species (1859) along with his birthday (1809). Astronomy fans commemorate 1543, when Copernicus placed the sun at the center of the solar system. […]

50 years ago, drug abuse was higher among physicians than the public

The American Medical Association estimates that some 60,000 of the country’s 316,000 doctors misuse drugs of various kinds. The drug abuser among physicians has a predisposing personality for addiction, and suffers from overwork and fatigue. […]

Geneticists close in on how mosquitoes sniff out human sweat

Geneticists have found a scent-sniffer protein molecule in mosquito antennae that — if somehow jammed — might leave a bloodsucker confused about whether we’re human enough to bite. Aedes aegypti mosquitoes, which can spread Zika and dengue, prefer human blood to the blood of other animals. A string of experiments now shows that a protein […]

Meet one of the first scientists to see the historic black hole image

It’s hard to say which scientist was the first to set eyes on the glowing ring that makes up the world’s first image of a black hole. But astrophysicist Kazunori Akiyama was certainly one of the earliest. The image, released to the public on April 10, revealed the dark shadow of the supermassive black hole […]
