  • GM mosquitoes cut rate of viral disease in Brazil

    Tweaking the genes of mosquitoes that can carry disease can sometimes transform those blood suckers into weapons that fight disease. This is the finding of a new study in Brazil.

    Dengue (DEN-gay) fever is a viral disease spread by Aedes aegypti mosquitoes. This potentially life-threatening infectious disease causes high fevers, headaches, pain and sometimes mild to severe bleeding....

  • Frigate birds spend months without landing

    Even the famous pilot Amelia Earhart couldn’t compete with the great frigate bird. Earhart flew nonstop across the United States for 19 hours in 1932. The frigate bird can stay aloft up to two months without landing, a new study finds. The seabird uses large-scale movements in the air to save energy on its flights across the ocean. By hitching a ride on favorable winds, the bird can spend more...

  • Current coral bleaching event is the longest known

    Coral reefs won’t be out of hot water for quite a while. These normally colorful undersea ecosystems are under increasing stress, mostly because of warming oceans. Now, researchers report that a global coral bleaching event began in June 2014. The longest on record, it has sapped the color out of vast areas of coral — and now threatens their health. The reefs affected cover a larger area than...

  • This mammal has the world’s slowest metabolism

    There are degrees of slothfulness, even when it comes to sloths. And three-toed sloths may be the most slothful of all, new data show.

    Researchers studied two species of sloth in Costa Rica. They measured the rate at which these animals’ bodies operate, converting food to fuel and growth. And this metabolic rate in one species of three-toed sloth was the lowest ever recorded — not just...

  • Singing lemurs sync up — until one goes solo

    Lemurs are a type of primate with huge eyes and a long tail. They live on Madagascar, an island country that sits off the East Coast of Africa. One species — the Indri indri  — sings. Or, at least, it kind of honks and howls and roars. Very distant relatives of humans, the indris usually sing in a chorus. But new research shows that young males crave the spotlight. Not content to be background...

  • Snout goo may help sharks sense prey

    Sharks appear to have a sixth sense that helps them locate prey in murky ocean waters. These fish rely on special electricity-sensing pores on their heads and snouts. The pores were first described in 1678. Even now, however, scientists aren’t quite sure how they work. But new data have just brought them a step closer.

    These pores are known as ampullae (AM-puh-lay) of Lorenzini. They...

  • Leapin’ eels! Video shows they attack with zaps

    Sometimes large, land-based predators threaten to attack electric eels from above. When that happens, these eels can leap at the threat from the water, a new study finds. And upon contact, those eels can deliver high-voltage attacks to ward off the invader.

    Kenneth Catania is a biologist at Vanderbilt University in Nashville, Tenn. He has been studying electric eels for years. He reports...

  • How a moth went to the dark side

    Scientists have just uncovered a gene that explains an example of natural selection often mentioned in textbooks. This gene turns mottled-grey peppered moths black. The gene may also control wing-color changes in brightly hued butterflies.

    A mystery emerged in Britain during the 1800s. An Industrial Revolution had just taken hold. Busy factories started to darken the skies with smoke...

  • The turning of wolves into dogs may have occurred twice

    Dogs were such great friends that humans appear to have domesticated them at least twice, a new study suggests.

    Domestication (Doh-MES-ti-KAY-shun) is the gradual process by which humans can produce a tame and useful animal from a wild one. This happens over countless generations. It may take thousands of years, but eventually the tamed animals can become so different from their wild...

  • Teens use science to worm through plastic waste

    PHOENIX, Ariz. — Four teens set out to study what turns mealworms into plastic eating powerhouses. The right worm could munch through a plastic mountain, they found. But all worms aren’t the right ones. Another surprise: Bigger isn’t always better.

    The high-school students showed off their results here, last month, at the Intel International Science and Engineering Fair. Created by...
