In 2015, massive wildfires burned through Indonesia, sending thick smoke and haze as far as Thailand. These fires were “the worst environmental disaster in modern history,” says Thomas Smith, a wildfire expert at King’s College London. Smith estimates that the fires and smoke killed 100,000 people in Indonesia and neighboring countries and caused billions of […]
The sex organs of primitive plants are inspiring precise pipettes. Liverworts are a group of ground-hugging plants with male and female reproductive structures shaped like tiny palm trees. The female structures nab sperm-packed water droplets by surrounding them with their fronds, like an immobilized claw in an arcade machine. Scientists have coopted that design to […]
The Red Sea is invading the Mediterranean.… So far about 140 life-forms, mostly animal and mostly invertebrate, have crossed the Isthmus of Suez.… It is possible that this … will result in the loss of a few native fish and invertebrate populations to stiff competition from the newcomers. — Science News, March 30, 1968 UpdateWhether […]
People who reached what’s now Canada’s Pacific coast around 13,000 years ago made some lasting impressions — with their feet. Beach excavations on Calvert Island, off British Columbia’s coast, revealed 29 human footprints preserved in clay-based sediment, says a team led by archaeologist Duncan McLaren. About 60 centimeters below the sandy surface, the deposits contained […]
An unknown killer preying on pigs in China has been identified as a new kind of coronavirus. And like the deadly SARS virus, this one also got its start in bats. In late 2016, pigs mysteriously started having intense diarrhea and vomiting on farms in China’s southeastern Guangdong province. By May 2017, the disease had […]
It’s no secret that warming ocean waters have devastated many of the world’s coral reefs. For instance, a 2016 marine heat wave killed 30 percent of coral in the Great Barrier Reef, a study published online April 18 in Nature reports. But some coral species may be able to adapt and survive in warmer waters […]
If you’re a female computer scientist, you may not see an equal number of men and women working in your field in this century — or even the next one. It might take a whopping 280 years for that scientific discipline to bridge the gender gap, researchers report online April 19 in PLOS Biology. The […]
Private web browsing isn’t nearly as private as many people think. Major web browsers, such as Google’s Chrome and Apple’s Safari, offer a private browsing option, sometimes known as “incognito.” The option allows people to surf the internet through a private window that doesn’t log activity into the browser’s history or influence future autofill recommendations. […]
An artificial intelligence that navigates its environment much like mammals do could help solve a mystery about our own internal GPS. Equipped with virtual versions of specialized brain nerve cells called grid cells, the AI could easily solve and plan new routes through virtual mazes. That performance, described online May 9 in Nature, suggests the […]
A genie in a bottle might grant you a wish, but neutrons trapped in a bottle aren’t so accommodating. Outside of an atomic nucleus, the neutral particles eventually decay into other particles. But scientists aren’t sure exactly how long neutrons stick around for before their demise: Two types of neutron lifetime measurements disagree. One type […]
