Ancient bones, artifacts and texts offer numerous insights into the past, as does the chewing gum that Neolithic people chewed on and spat out long ago. Analysis of lumps of birch bark tar from ancient settlements has revealed ...

Faulty versions of the LMNA gene can cause a wide range of health problems, including heart muscle disease (dilated cardiomyopathy) and muscle weakness (muscular dystrophies). Many of these diseases are caused by single-point ...

There could soon be a new way to interact with your favorite AI chatbots—through the clothing you wear. An international team of researchers has developed a voice-sensing fabric called A-Textile. This flexible patch of smart ...

Scientists have come up with a new way to improve the safety and performance of all-solid-state lithium metal batteries (ASSLMBs), the next-generation energy source technology that is set to power everything from electric ...

Whether we're talking about animals or humans, gut microbes are essential for health, metabolism and protecting against infection. While captivity is known to alter the gut microbiota of wildlife, the relative influence of ...

Naked mole-rats are one of nature's most extraordinary creatures. These burrowing rodents can live for up to 37 years, around ten times longer than relatives of a similar size. But what is the secret to their extreme longevity? ...

Large language models (LLMs), which power sophisticated AI chatbots, are more vulnerable than previously thought. According to research by Anthropic, the UK AI Security Institute and the Alan Turing Institute, it only takes ...

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 ...
