In July 2023, researchers on a whale watching expedition in the Caribbean Sea encountered an unusual scene: 11 sperm whales clustered tightly at the water’s surface.The animals began to inch closer and closer together in the waters off the island of Dominica, with their attention turned to one individual, until a burst of blood tinted the water.At first, the scientists—part of @ProjectCETI, a nonprofit that studies how sperm whales interact—thought the animal had been attacked. But then they saw

For #DNADay: Welcome to the nanosize railway. Much as a train switchyard can steer rail cars to different locations, researchers have engineered protein motors to carry tiny bits of cargo to different locations. In the body, protein motors ferry nutrients and other materials along tiny tube-shaped rails that crisscross cells. Nanotechnologists have made their own versions for years using tube-shaped rails made from DNA. Last year, researchers took that approach one step further, creating DNA nan

In a lab in central Pennsylvania, a fly is suspended in a magnetic field inside a dome lined with rotating LED bulbs. The insect flaps its wings and spins, believing it’s actually buzzing through this virtual reality environment—one that can even distort what the fly sees. Though unusual, this tiny virtual reality flight simulator has a deeper purpose. Here, researchers are probing the inner workings of the insect brain.

Rattlesnakes in arid landscapes often coil their bodies when it rains to gather and sip drops from their sticky scales. But they can also nab water from the skin of nearby snakes, according to a new study reported in Current Zoology.

Elephants love showering to cool off, and most do so by sucking water into their trunks and spitting it over their bodies. But an elderly pachyderm named Mary has perfected the technique by using a hose as a showerhead, much in the way humans do. The behavior is a remarkable example of sophisticated tool use in the animal kingdom. But the story doesn’t end there. Mary’s long, luxurious baths have drawn so much attention that an envious elephant at the Berlin Zoo has figured out how to shut the w

Science Magazine on Instagram: "“Iron chef” just got a whole new meaning. Researchers have designed a robot that can create and cook a cake with up to seven ingredients, more than any other printed food to date. Initial trials resulted in triangular gobs of sweet goo, so the researchers came up with a winning recipe that could hold its own. They nested softer ingredients, such as jelly and banana puree, inside of stiffer ingredients, such as peanut butter and Nutella, then reinforced those with

Some of today’s most advanced robots can leap over obstacles, crawl through tight spaces and swim gracefully—as long as they’re traveling in straight lines. Making turns, however, often poses a challenge to so-called biohybrid machines, which combine living tissue with robotic materials. Now, scientists from Japan report in Matter that they have created a bipedal biohybrid bot that can turn on a dime, albeit slowly. If the technique can be made to work in other biohybrids, it could help these ma

With their spearlike noses, high-speeds, and group attacks, striped marlin (Kajikia audax) are fearsome predators of sardines and other small fish. But how do they avoid impaling one another during these mêlées? New drone footage may provide the answer. As seen in this video, right before a marlin attacks a school of sardines, it changes color, dialing up the contrast of the stripes along its body.

By sampling books for ancient DNA and proteins, researchers can reveal the organisms that interacted with ancient books, from the animals whose skins are preserved as parchment to the bookworms and people who once lingered over the pages. They can even isolate the microbes spewed on manuscripts when people kissed, coughed, or sneezed on them.

Spiderman famously does whatever a spider can—including spinning webs and bounding though the air. But what about the superhero’s habit of slinging perfectly aimed webs to catch nimble nemeses? Turns out he gets that from spiders, too: Researchers report in the Journal of Experimental Biology that ray spiders (Theridiosoma gemmosum) not only catapult their sticky webs to ensnare mosquitoes, but also accurately detect where and how fast their prey is moving.

The human brain can bring rubber to life with one simple trick: Cover a person’s hand and place a rubber hand next to it, then stroke their hand and its facsimile, and suddenly the person will begin to “feel” the touch in the fake appendage. The rubber hand illusion helps demonstrate how our senses work together to create the feeling of ownership over our bodies, a fundamental part of self-awareness. And now, a new study in Current Biology demonstrates that octopuses also fall for the rubber arm

When key “housekeeper” brain cells grow in lab dishes, they spawn unusual microscopic vesicles that can move on their own and carry energy-generating organelles, a research team has revealed. The biologists have dubbed their discovery zombosomes because the blobs can move like cells for a period despite lacking a nucleus, which acts as a cell's control center. The group also showed the membrane-bound messengers ferry proteins related to Parkinson’s disease, suggesting they may contribute to it a

Now, thanks to a hospital CT scanner, researchers have revealed new insights into how these insects build their subterranean lairs. The study investigates nests of two common species of ground-nesting bees. One, the spring mining bee (Colletes cunicularius), is solitary; each female builds a nest over a few days, collecting pollen by herself and laying eggs before ab

Sometimes, being squishy is the key to success. Modern cephalopods—the group that includes squids, octopuses, and cuttlefish—are known for their soft, pliable bodies, a trait that makes them faster and more agile in the water than their shelled ancestors. But because soft tissues rarely fossilize, the evolutionary origins of these iconic animals remain somewhat mysterious. Now, research published in Science demonstrates a new way to uncover hidden squid fossils—and reveals that the critters star
