"I can look at an object in the world around me, but I can also close my eyes and imagine the object," says Varun Wadia, highlighting the dual capability of visual perception and imagination.

The protein in the new study is called TRPM8, and it acts as the body's primary receptor for sensing both menthol and cold temperatures. It's a channel embedded in cell membranes that opens when triggered by dropping temperatures or cooling agents.

The researchers at Eon Systems have taken several pre-existing components: a fruit fly brain scan, a tool for modelling neurons, a model of some of the fly's muscles and body, and a very simple virtual environment, connected them together and ran it. The team claims that the result displays some of the behavior of the real insect.

For a long time, scientists believed that it would be impossible for a cat in free fall to turn over. That's why French physiologist Etienne-Jules Marey's 1894 high-speed photographs of a falling cat landing on its feet proved so shocking to Marey's peers. But Gbur has emphasized that cats are living creatures, not idealized rigid bodies, so the motion is more complicated than one might think.

Unlike sight or sound, smell has a direct pathway to the amygdala and hippocampus-the regions involved in emotion and autobiographical memory. Because of this connection, memories triggered by scent are often more vivid and emotionally intense than those triggered by sight.

At a time when memories are increasingly flattened into folders, feeds, and cloud backups, a new experimental device from MIT Media Lab proposes a far more intimate archive: scent. Developed by Cyrus Clarke, the Anemoia Device is a speculative yet functional prototype that translates photographs into bespoke fragrances using generative AI, inviting users not to view memories, but to inhabit them through the body.

An elephant's trunk is a marvelous thing, flexible enough to bend and stretch as it forages for food, but also stiff enough to grasp and maneuver even delicate objects like peanuts or a tortilla chip. That's because the trunk is highly sensitive when it comes to sensing touch. Scientists have determined that the whiskers lining the trunk are crucial for that sensitivity thanks to their unique structure, amounting to a kind of innate "material intelligence, according to a new paper published in the journal Science.

Bats are impressive navigators. Like so many mini submarines equipped with sonar, they deftly navigate dark forests and caves by listening for the echoes of their own calls. But how bats can tell which echo to follow while flitting around in a sea of overlapping and competing signals pinging off the myriad surfaces in their environments has been a mysteryuntil now.

Real estate with ocean views, stunning mountain vistas, and wide-open green spaces sell at premium prices because humans find those settings pleasing [1-5]. Certain color combinations in fashion-such as brown and forest green-blend harmoniously, while others, such as hot pink and orange, clash. And our eyes like certain proportions in visual objects (like buildings and human faces) but not others.

Last November, the UK government announced a bold plan to phase out animal testing in some areas of research. Animal tests for skin irritation are scheduled for elimination this year, and some studies on dogs should be slashed by 2030. The long-term vision is 'a world where the use of animals in science is eliminated in all but exceptional circumstances'.

Recently, two unexpected examples by a wild wolf and a domesticated cow named Veronika attracted global attention and once again opened the door for experts and others to weigh in on the question, "Are these really examples of tooling?" Many people are eager to know more about the nitty-gritty details of tooling, so I am thrilled that Dr. Benjamin Beck, an expert in this area, could answer a few questions about this fascinating behavior.

Some deep-sea fish may be able to see light in a different way from most other vertebrates, according to a new study. The fish, found in the Red Sea, have what the scientists behind the new study describe as hybrid photoreceptorslight-sensing cells in the retina that combine elements of two distinct kinds of photoreceptors, cones and rods. In human retinas, cone cells enable us to see in bright environments, detecting color and fine detail,

Countless millions of nonhuman animals (animals) of all sorts are used in a diverse array of laboratory research. Their treatment varies from being unspeakably inhumanely abused to being treated with kindness, depending on the questions at hand and the values and attitudes of the researchers themselves. The lives of these animals truly are hidden, and most people are incredulous when they learn that laboratory rats and mice still are not considered "animals" under the current federal Animal Welfare Act.

The list of feats Andrew Schulz has witnessed an elephant perform with its trunk is as long as, well, an elephant's trunk. These powerful proboscises are strong enough to push over 900 pound trees and gentle enough to pick up a tortilla chip without breaking it. They can snuffle along the ground to sense vibrations from far-off herd movements. They can be used to solve puzzles, peel bananas, craft tools, console a fellow pachyderm or a human friend.
