For the first time, scientists have created a fully functional memory chip only a few atoms thick and integrated it into conventional chips. This advance could pave the way for more powerful and energy-efficient electronic ...

Training animals in captivity is extraordinarily challenging due to a host of factors such as an animal's natural temperament and prior negative experiences with humans. But it is often essential in places like zoos and conservation ...

Most people enjoy receiving praise occasionally, but if it comes from sycophantic chatbots, it could be doing you more harm than good. Computer scientists from Stanford University and Carnegie Mellon University have found ...

Antarctic krill, tiny shrimp-like creatures, are an important species in the Southern Ocean ecosystem and global carbon cycle, in part because of their poop. Their dense and rich fecal pellets sink rapidly, transporting carbon ...

Drones have become a more common sight in our skies and are used for everything from consumer hobbies like aerial photography to industrial applications such as farming, surveillance and logistics. However, they are not without ...

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants of dead stars.

Inside nearly every cell of your body, the tiny F1 motor works non-stop to create adenosine triphosphate (ATP), the universal energy source that powers almost every action you take—from breathing to running. While scientists ...

Bivalves, such as clams, oysters and mussels, record seasonal environmental changes in their shells, making them living chronicles of climate history. A new study of bivalve shells has detected two major episodes of instability ...

Artificial intelligence is transforming biology and medicine by accelerating the discovery of new drugs and proteins and making it easier to design and manipulate DNA, the building blocks of life. But as with most new technologies, ...

As many dog owners can attest, their four-legged companions are delightful and loving. But for others, their animals have an aggressive side, such as biting and attacking strangers, which may ultimately lead to them having ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ERVs) that infected our ...

What did early humans like to eat? The answer, according to a team of archaeologists in Argentina, is extinct megafauna, such as giant sloths and giant armadillos. In a study published in the journal Science Advances, researchers ...

More than 90% of plastic waste ends up in the soil, where it breaks down into microplastics that are invisible to the naked eye. Microplastic pollution of the soil poses a severe threat to soil health as it can harm essential ...

Plastic may well be a useful everyday item, but its careless disposal in oceans and inland waterways is a pressing global problem. Plastic pollution poses a significant threat to human health and the health of our planet. ...

Researchers have uncovered serious security flaws with the Unitree G1 humanoid robot, a machine that is already being used in laboratories and some police departments. They discovered that G1 can be used for covert surveillance ...
