Imagine trying to listen for a whisper while making a loud noise yourself. An African elephantnose fish faces a similar problem underwater. It sends out small electric pulses to explore its surroundings, but those pulses could drown out the faint signals it needs to detect food and other fish. The fish has sensors in its […]

Most products made for pets are designed entirely by humans. But what if animals could help design the things they use? A new project suggests they can. Researchers worked with a pet parakeet named Shiso to create a wearable perch based on the bird’s own preferences, turning the design process into a true collaboration between […]

Dogs may have more in common with humans than just sharing our homes and routines. A new study has found that the same biological signals linked to lifespan in people also appear in dogs, suggesting that both species may age in remarkably similar ways. The research comes from the Dog Aging Project, a long-term study […]

When a whale dies, a very special natural phenomenon can come alive. The carcass might float at the surface for some time, attracting sharks and other predators. As it becomes weathered, it may start to sink, falling through the water until it eventually settles on the seafloor, where deep-sea scavengers feast upon it. The scientific […]

Rice is one of the world’s most important foods, providing a daily source of calories for nearly half of the global population. It is also an important source of magnesium, a mineral that helps support healthy muscles, nerves, bones, and energy production in the human body. Scientists have long known that magnesium plays an important […]

Researchers from Okinawa Institute of Science and Technology and Japan Agency for Marine-Earth Science and Technology have identified how bacteria can adapt to toxic metals released from hydrothermal vents. The study focused on Nitratiruptor sp. SB155-2, a species of bacteria isolated from vents in the Okinawa Trough. The researchers found that bacteria use transporter proteins […]
