The coral reef, once bustling with more than 5,000 long-spined sea urchins, became a ghost town in a matter of days. White skeletons with dangling spines dotted the reef near the Dutch Caribbean island of Saba, the water cloudy from the disintegrating corpses. In just a week last April, half of the urchins, Diadema antillarum, in a section of reef called “Diadema City” had died. In June, only 100 remained.
In Ipswich, when temperatures are well below freezing and the tidal flats are covered in ice, Paul Damon still digs for clams. Even when it dips to 11 or 12 degrees, he’ll take his boat to reach the flats — exposed expanses of mud that appear at low tide. Only when he tosses out the anchor and it bounces off the solid mud does he head home.

The frill that haloes the head of Triceratops is an iconic part of its look. Equally iconic, at least to paleontologists, are the holes that mar the headgear. For over a century, researchers have debated various explanations for the holes, called fenestrae — from battle scars to natural aging processes.
Julius Nziza still remembers the moment vividly. Just before dawn on a chilly January morning in 2019, he and his team gently extracted a tiny brown bat from a net purposely strung to catch the nocturnal fliers. A moment later, the researchers’ whoops and hollers pierced the heavy mist blanketing Rwanda’s Nyungwe National Park.
You can never have too much ice cream, but you can have too much ice in your ice cream. Adding plant-based nanocrystals to the frozen treat could help solve that problem, researchers reported March 20 at the American Chemical Society spring meeting in San Diego.
During the COVID-19 pandemic’s delta variant wave, schools that required masking had approximately one-fourth the rates of in-school coronavirus transmission than schools with optional or partial masking policies, researchers report online March 9 in Pediatrics.
Before the early 1900s, if it walked like a Christmas Island rat and talked like a Christmas Island rat, it probably was a Christmas Island rat. But if one of these now-extinct rats ever walks the Earth again, it will most likely be a genetically modified Norway brown rat. And the rodent won’t be as similar to the Christmas Island rat as some would hope, a new study finds.
Sponges are microbe paradises, capable of housing 54 billion bacteria per cubic centimeter. In addition to being damp, airy and loaded with food scraps, sponges provide an optimal physical environment for bacteria, researchers report February 10 in Nature Chemical Biology.
Lizards are famous for losing their tails, but perhaps the bigger question should be: How do their tails stay on? The answer may lie in the appendage’s internal design. A structure of prongs, micropillars and nanopores holds a lizard’s tail on tight enough to handle most jarring while remaining primed to drop the tail in case of emergency, researchers report in the Feb. 18 Science.
If you’re an athlete—even a very occasional one—odds are you’ve dealt with a muscle injury at some point. After all, muscle injuries account for 10 to 55 percent of sports traumas. https://nautil.us/blog/torn-muscle-hold-the-drugs-or-surgerymassage-may-be-the-best-medicine
The national trend to shop locally has skyrocketed in recent years. And thanks to a couple global crises – a warming climate and a raging pandemic – it’s a trend that is here to stay. Increasingly, consumers want to buy ethically and closer to home; shopping locally achieves both. New research shows that 41% of consumers intend to buy more locally going forward.
On a humid Tuesday morning, while volunteering at a reforestation nonprofit in Brazil, I trekked through the Atlantic Rainforest to the nonprofit’s office. The forest was already wide awake and noisy with insects and birds. Inside the office, one of the nonprofit coordinators, Virgilío Dornelas, was making coffee for the two of us.
