Editor’s Note: Regular readers of this column know we never pass up the chance to share a story about our beloved water bears. 🙂 For the first time, scientists have figured out how tardigrades — some of the toughest creatures on the planet — mate. These tiny, hardy critters have few obvious differences between males … Read more
Ocean pout live in frigid waters from Labrador in Canada to North Carolina and have evolved a blood protein that serves as antifreeze. Name: Ocean pout (Zoarces americanus) Where it lives: Western Atlantic Ocean, ranging from Labrador in Canada to North Carolina, in waters from near the shore to depths of almost 1,300 feet (400 … Read more
Scientists have unearthed 188 previously unknown types of CRISPR systems buried in the genomes of simple microorganisms. Best known as a powerful gene-editing tool, CRISPR actually comes from an inbuilt defense system found in bacteria and simple microbes called archaea. CRISPR systems include pairs of “molecular scissors” called Cas enzymes, which allow microbes to cut … Read more
Some marine worms have developed a strange reproduction strategy: They essentially grow a second worm on their rear ends, head and all. This bizarre twin then breaks off and swims away to mate with other swimming butts of the opposite sex. In a study published Nov. 22 in Scientific Reports, researchers described exactly how Japanese … Read more

In the forest, certain fungi attach to trees and fallen logs to break down and digest the carbon within their wood before releasing it as carbon dioxide. But when their preferred meal isn’t available, these wood-decaying fungi can chow down on plastic instead, according to a new study published July 26 in the journal PLOS … Read more
A 64-year-old man got a medical checkup after his tongue began sprouting green “hairs.” The bizarre-looking fuzz turned out to be caused by a fairly common and harmless condition known as hairy tongue. The patient’s tongue had turned green about two weeks before he visited the clinic, shortly after he had completed a course of … Read more
Lab-grown meat, made from chicken cells cultured in steel tanks, can now be produced and sold in the U.S. for the first time. Two California-based companies — Upside Foods and Good Meat, a subsidiary of Eat Just — became the first in the nation to get approval from the U.S. Department of Agriculture (USDA) to … Read more
Neanderthal genes may be one cause of the disorder nicknamed the “Viking disease,” in which fingers become frozen in a bent position, a new study finds. The study, published June 14 in the journal Molecular Biology and Evolution, finds gene variants that were inherited from Neanderthals that dramatically increase the odds of developing the condition, … Read more
Mysterious, spiral signals have been discovered in the human brain, and the scientists who found the swirls think they could help to organize complex brain activity. The signals, which appeared as swirling spirals of brain waves across the outer layer of the brain, were discovered in functional magnetic resonance imaging (fMRI) brain scans of 100 … Read more
