Texts from imperial China suggest that some crimes were punishable with unusual amputations and a 700-year-old skeleton appears to offer the first physical evidence of the practice
Artificial intelligence is rapidly becoming part of how people learn, solve problems and construct knowledge. Yet whether AI strengthens human intelligence or encourages excessive dependence remains an open question.
Plug-in solar panels offer reduced bills and can help boost renewable energy on Great Britain's grid, but concerns around their safety remain
Scientists are testing a counterintuitive way to fight mesothelioma, an aggressive asbestos-linked cancer with few effective treatments. A new experimental mesothelioma drug kills cancer cells by disabling PRX3, an antioxidant defense that tumors use to survive intense oxidative stress. In an early clinical trial, it controlled disease progression in 67% of patients and produced encouraging survival results, raising hopes that the strategy could eventually be used against other cancers.
Scientists have found the first evidence that liquid may have flowed across Pluto’s surface in the recent past. Dark features on the enormous Sputnik Planitia glacier appear consistent with liquid nitrogen rising through cracks from deep beneath the ice. Computer models show that nitrogen could melt at the glacier’s base and travel upward like fluid through small conduits. The finding reveals that Pluto may be much more geologically active than its frozen appearance suggests.
Scientists found that black and green Japanese rice contain unusual, potentially beneficial fats and may be digested more slowly than ordinary white rice. The combination could make these colorful varieties promising ingredients for foods designed to support blood sugar and metabolic health.
For many, the Bayeux Tapestry conjures images of clinker-built ships, prancing horses, the Normans feasting on chicken on the eve of the Battle of Hastings, and the arrow in King Harold's eye that ended centuries of Anglo-Saxon rule.
Scientists discovered a hidden “immune organ” inside the skull that acts as a rapid first responder against brain cancer in mice. Strengthening this local immune defense improved tumor rejection and survival, raising the possibility of new treatments that target the skull directly.
When most Australians say 'spring is in the air,' they're speaking metaphorically, as the days become longer and warmer.
It's not so much where people live, but where they frequently spend their time, that can provide useful information for predicting community health measures. A team led by geographers in the Penn State College of Earth and Mineral Sciences found that adding place visitation data—geographic data points collected from millions of anonymous cellphone users with GPS-enabled devices—to a population health model increased the model's predictive performance by an average of 7.5%.
Understanding the migration pathways of sharks and rays is key to conserving some of the world's most endangered marine species, according to new University of Queensland research.
A new report by the International Bar Association (IBA) has found a significant gap between the importance legal professionals attach to fundamental rule of law principles and their assessment of how effectively those principles are implemented in practice.
A study in Pollino National Park shows that large trees, complex canopies and deadwood diversity play a major role in shaping vascular plant communities, highlighting the ecological value of one of Italy's most remarkable old-growth forest landscapes.
Large-scale oyster reef restoration in the Chesapeake Bay is successfully creating three-dimensional habitats that support larger, more diverse fish communities, according to new research from scientists at the University of Maryland, Baltimore County (UMBC), the Smithsonian Environmental Research Center and the National Oceanic and Atmospheric Administration (NOAA). The study, published in Ecosphere, provides compelling evidence that restoration efforts are shifting underwater ecosystems from communities dominated by small, transient schooling fish to those supporting larger, resident species.
Biofilms are complex microbial communities that adhere to a surface and encase themselves in a viscous matrix they produce. This structure protects bacteria from antibiotics and the immune system far more effectively than if they lived in a free-floating state, making biofilms one of the most common causes of hard-to-treat chronic infections—such as respiratory infections in people with cystic fibrosis and chronic obstructive pulmonary disease (COPD), chronic wounds, or infections associated with catheters and prosthetic devices. Added to this is the global rise in antibiotic resistance, which makes it increasingly urgent to have tools capable of predicting which treatment will work in each ...
When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material's atomic lattice, known as phonons. They may also collide with one another. Frustratingly, a conventional temperature test warms the electrons and the lattice together, so the effects arrive tangled in the same resistance measurement.
Forty-four years ago, Nadrian Seeman published his groundbreaking ideas on using DNA as a structural material, expanding DNA's significance far beyond its role as a carrier of genetic information. Since then, the steadily growing field of DNA nanotechnology has seen numerous innovations. One was the DNA origami technique, which enables researchers to fold a single long strand of DNA into a desired 2D or 3D shape.
What factors influence students' decisions about whether they will continue to use ChatGPT for learning in the future? This was the question addressed by a new study from ELTE's Faculty of Informatics, which used an interpretable machine learning framework to identify the factors that most strongly influence the use of generative artificial intelligence in higher education.
A square peg doesn't fit a round hole. But what if the peg could change the shape of the hole? A newly developed drug molecule can do something surprisingly similar when binding to its target protein, according to a University at Buffalo-led study published Tuesday (Sept. 15) in Angewandte Chemie International Edition.
Sir John Gage, a key figure in Henry VIII's dissolution of the monasteries, saved a dangerous Catholic book from likely destruction, a new study suggests. The identification of six lost pages of a medieval bestseller—illicitly prized by Catholics in the Reformation—as belonging to Gage, exposes the split loyalties of one of Tudor England's great survivors.
