Scientists have found what they believe to be the earliest known evidence of wine drinking in the Americas, inside ceramic artefacts recovered from a small Caribbean island.

Neurons in a key area of the brain have different functions based on their exact genetic identity, and understanding this diversity could lead to better understanding of the brain's computational flexibility and memory capacity, potentially informing disease treatment options, researchers report.

Researchers analyzed THC levels in the breath of people who use cannabis regularly, both before and after they smoked marijuana. The researchers found that THC levels spanned a similar range across pre- and post-use samples. 'In many cases, we would not have been able to tell whether the person smoked within the last hour based on the concentration of THC in their breath,' said study author.

Researchers have recorded pain-related data from inside the brain of individuals with chronic pain disorders caused by stroke or amputation (phantom limb pain). A long sought-after goal has been to understand how pain is represented by brain activity and how to modulate that activity to relieve suffering from chronic pain. Data were collected over months while patients were at home, and they were...

Current climate policies will leave more than a fifth of humanity exposed to dangerously hot temperatures by 2100, new research suggests.

A tiger-sized saber-toothed creature called Inostrancevia has previously only been found in Russia. But scientists have discovered its fossils in South Africa, suggesting that it migrated 7,000 miles across the supercontinent Pangaea during the world's worst mass extinction 252 million years ago. Heading to South Africa allowed it to fill a gap in a faraway ecosystem that had lost its top...

Researchers took a deep dive into the economic and environmental value of community recycling efforts and compared it to the value of other climate change mitigation practices, concluding it provides a return on investment.

Engineers have developed the first fully integrated wearable ultrasound system for deep-tissue monitoring, including for subjects on the go.

Researchers have shown that within immune structures called the germinal centre, the mislocation of Tfh cells causes reduced capacity to respond well to vaccination with age. The research also identified that Tfh cells have a previously unappreciated role in supporting stromal cell responses to vaccines. The research demonstrates that age-dependent defects in the germinal centre response are...

A University of Minnesota Twin Cities-led team has developed a first-of-its-kind breakthrough method that makes it easier to create high-quality metal oxide films that are important for various next generation applications such as quantum computing and microelectronics.

The first instrument to directly measure gravity on the surface of an asteroid has undergone testing in ESA's Mechanical Systems Laboratory.

A team of researchers has created a new supply chain model which could empower the international hydrogen renewable energy industry.

Astronomers using the most powerful telescope ever built have identified a massive, densely packed galaxy 25 billion light years away.

Using an aeronautic remote sensing system, Chinese scientists have obtained effective mountain glacier data during an ongoing airborne-ground science experiment on detecting the condition of Bayi Glacier in Haibei Tibetan Autonomous Prefecture, northwest China's Qinghai Province, according to the Aerospace Information Research Institute (AIR), Chinese Academy of Sciences (CAS).

Natural landscapes are continually transformed to make room for agricultural and urban developments—often at the expense of important habitats and species.

Scientists have found what they believe to be the earliest known evidence of wine drinking in the Americas, inside ceramic artifacts recovered from a small Caribbean island. Forty ceramic sherds were examined in the first study to have used molecular analysis techniques—Gas Chromatography and Mass Spectrometry—to investigate 15th century pottery from the Puerto Rico region.

Writing in the May 22, 2023 issue of Cell Systems, a diverse team of scientists, led by researchers at University of California San Diego School of Medicine, have produced a novel map that depicts the human body's enormously complicated and highly evolved system for addressing and repairing DNA damage—a cause and consequence of many diseases.

Did you know that wires can be used to ionize air to make a loudspeaker? Simply put, it's possible to generate sound by creating an electric field in a set of parallel wires, aka a plasma transducer, strong enough to ionize the air particles. The charged ions are then accelerated along the magnetic field lines, pushing the residual non-ionized air in a way to produce sound.

Meta has built AI models that can recognize and produce speech for more than 1,000 languages—a tenfold increase on what’s currently available. It’s a significant step toward preserving languages that are at risk of disappearing, the company says. Meta is releasing its models to the public via the code hosting service GitHub. It claims that making them open source will help developers...

The great—if sometimes overlooked—20th-century philosopher and cultural critic Günther Anders once proposed that our modern age is characterized by a dangerous and pervasive "Apocalypse-Blindheit": a blindness to the apocalypse.

Imagine coming across an injured kangaroo on the side of the road. Or a bat entangled in fruit tree netting. Would you know who to call to get help?

The next time you fly, be sure to secure a window seat opposite the Sun — and pray for clouds. Under the right conditions, you just might see a glorious atmospheric phenomenon known as, well, the glory. The glory is an optical effect that appears as a series of concentric colored rings on clouds orContinue reading "Secret Sky: High-flying glory" The post Secret Sky: High-flying glory appeared...

Europe's coasts are densely populated and already affected by the impacts of sea level rise. In addition to traditional, cost-intensive coastal protection measures, spatial land use planning strategies are becoming increasingly important to protect coastal communities from damage during high tides or storm surges. Such planning tools include managed retreat or even the establishment of so-called...
