A remarkable prehistoric hammer made from elephant bone, dating back nearly half a million years ago, has been uncovered in southern England and analysed by archaeologists from UCL and the Natural History Museum, London. It is the oldest elephant bone tool to ever be discovered in Europe and provides an extraordinary glimpse into the ingenuity of the early human ancestors who made it.

CEA-Leti Demonstrates Combined MicroLED and Organic Photodetector Architecture For Display-Integrated Optical Sensing -System-Level Approach Presented at Photonics West Co-Packages Device Design, Electronics, and Modeling for Multifunctional Display Applications SAN FRANCISCO - Jan. CEA-Leti today demonstrated a co-packaged microLED and organic photodetector (OPD) architecture that enables optical sensing functions.

A new University of Manchester and Edinburgh study published in the journal Brain, Behavior and Immunity has found that people who have had a stroke have fewer of a specific type of immune cell called B cells, which normally produce antibodies to fight off infections. Surprisingly, the same compromising immune changes were seen when healthy B cells were exposed to noradrenaline - a chemical released by the body after stroke, but also during stress, illness, or intense physical activity.

New Antarctica study involving Uni Bonn shows the influence of solar cycles on the stability of coastal ice The remnants of ice that was attached to the coast offer astounding insights into the climate history of past millennia. An international research team led by the CNR Institute of Polar Sciences (Italy) and involving the University of Bonn has applied a groundbreaking method.

A team from the Faculty of Medicine and Health Sciences and the Institute of Neurosciences at the University of Barcelona (UBneuro) has applied advanced artificial intelligence techniques to better understand why Huntington's disease can begin at very different ages in patients. This hereditary neurodegenerative condition, which causes motor, cognitive, and psychiatric impairments, is caused by a mutation in the HTT gene, which encodes the huntingtin protein.

At the Department of Ion Physics and Applied Physics at the University of Innsbruck, a research team has succeeded for the first time in storing electrically charged helium nanodroplets in an ion trap for up to one minute. This extends the time window for experiments with these extremely cold "mini-laboratories" by a factor of 10,000 compared to previous methods - and opens up new possibilities for basic research in physics and chemistry.

The mpox virus appears to be circulating silently in parts of Nigeria, in many cases without the symptoms typically associated with the disease, according to new research led by scientists from the University of Cambridge and partners in Nigeria. The findings may have implications for controlling the spread of the disease.

Many planetary systems consist not only of a central star and the planets orbiting it, but also of so-called debris disks. These regions contain small bodies such as asteroids, as well as large amounts of dust that is produced when rocky objects collide with one another. In our own Solar System, for example, beyond the orbit of Neptune lies the so-called Kuiper Belt, where larger debris is gradually ground down into dust.

A team from the University of Geneva shows that it is possible to determine the state of a quantum system from indirect measurements when it is coupled to its environment. What is the state of a quantum system? Answering this question is essential for exploiting quantum properties and developing new technologies.

Anyone who has ever had to get a magnetic resonance imaging (MRI) scan knows that magnetic and highly conductive materials are a no-go in the tube-shaped scanners. However, for complex diagnoses and medical research, this imaging technique often needs to be combined with other methods that require conductive cables.

Researchers at TU Graz and the University of Graz can use the technology to construct artificial biocatalysts. These new enzymes are significantly faster, more stable and more versatile than previous artificial biocatalysts. Enzymes with specific functions are becoming increasingly important in industry, medicine and environmental protection.

An interdisciplinary team including researchers at McGill University has found a range of unexpected chemical contaminants in human milk samples from Canada and South Africa. The chemicals include traces of pesticides, antimicrobials and additives used in plastics and personal-care products. The findings were published across five papers.

Native trees, such as oaks, have long held a special place in our culture and countryside. Now, researchers have shown that these trees are also important to woodland birds and their offspring. A new study, led by the University of Glasgow and published in the journal Ecology, shows that common woodland birds, such as blue tits, produce more chicks when surrounded by a greater abundance of native tree foliage.

By rethinking how thin metal threads are woven into a flexible textile, researchers have created a lightweight fabric capable of lifting over 400 times its own weight. The work advances the development of wearables that provide physical assistance without mechanical bulk. Most wearable robotic systems today rely on rigid components with limited comfort and social acceptance.

Researchers at the University of Bonn investigated the beliefs that influence consumers' willingness to buy animal-free Gouda. An increasing number of people are turning to vegan products. However, when it comes to cheese, this transition is proving difficult. One alternative is precision fermentation, in which microorganisms produce milk proteins to enable the production of genuine dairy products, such as cheese, without the need for cows.

Scientists seeking answers to the mystery of why cancer occurs in certain parts of the body and not others may have found a new way to tackle some hard-to-treat cancers. The research team focused on genetic faults that allow cancer to hijack a signalling system in the body which tells cells when, and when not, to grow.

Research team examines farmers' protest motivations and political responses in four EU countries Farmers' protests that swept across Europe in 2024 were driven by a wide range of concerns that differ markedly between countries, according to a new study led by researchers at the University of Göttingen.

Researchers from the Collaborative Research Centre (CRC) 1423 have, for the first time, investigated directly in living cells how a key membrane receptor - which, among other functions, helps regulate heart activity - interacts with its signalling partners. Depending on the drug applied, this receptor adopts different conformations and operates at different speeds, which in turn influences which signals are passed on within the cell.
