If you ever need help in the kitchen cutting fish into appetizing bites, a new three-armed robot may be able to help. And that's no easy feat for robots. While they are generally good at picking up rigid objects, something ...

When pigeons are flying through the air, they lock their eyes in a near-fixed position instead of moving them around. Researchers from Harvard University discovered this after attaching a lightweight rig of cameras and mirrors ...

AI is growing fast, and keeping up means building more data centers, manufacturing advanced chips and powering the tech behind it. All of that comes with a carbon cost. AI advocates claim that in the long run, AI will save ...

Goats appear to have a rare ability not shared by many in the animal kingdom, and that is being able to follow the direction of a human voice to locate hidden objects. While dogs have been shown to do this, even our closest ...

When female bottlenose dolphins want to avoid males known for pushy mating behaviors, they listen out for their unique signature whistles. That's the suggestion of a study published in Proceedings of the National Academy ...

We often hear about glacier melting and predictions of what climate change could do. But very little is mentioned about the effects on ecosystems or the animals that call them home. To redress some of this imbalance, an international ...

To accommodate the increasing demand for clean energy, researchers have been developing floating solar panels for rivers, reservoirs and other waterways in recent years. While there is, of course, plenty of land for solar ...

Archaeologists have discovered a game board carved into the steps of a medieval bathhouse in the Moroccan town of Walīla (the Roman city of Volubilis). The find is a rare example of a medieval game board that can be securely ...

Many insects will eat almost anything in their sight, such as certain beetles, grasshoppers and locusts, while others are remarkably picky eaters. For example, numerous insect herbivores will feed only on a single plant family ...

The Venus flytrap (Dionaea muscipula) is a marvel of nature, a highly effective killer that doesn't have to move an inch to capture and kill its prey. It releases a fruity nectar scent to attract flies and other insects. ...

Autonomous vehicles are already a reality on some of our streets and could become a major part of future transportation systems. Safety, of course, is the main concern, as with all vehicles. To help evaluate and improve its ...

Moon missions come in all shapes and sizes, from car-sized rovers packed with scientific equipment to towering rocket payloads—and now, a small, shape-shifting machine that is about the size of the average palm.

Since 2019, GPS signals across Europe, Greenland and Canada have experienced a huge spike in sudden, widespread signal blackouts. These have resulted in disruptions and degraded performance in navigation systems that airplanes ...

Just like left- or right-handed humans, domestic dogs have a preference for their left or right paw, a trait known as laterality. This can vary depending on the tasks they perform, which has made it difficult to create a ...

Ocean currents are not just horizontal motions that flow from side to side. There are also vertical currents that act like deep-sea elevators, pushing heat and carbon down into the deep, while bringing up vital nutrients ...
