Phys.org / Chemists synthesize first stable copper metallocene complex, closing a 70-year gap
Almost half a century ago, a remarkable molecule called metallocene took center stage in chemistry, earning Geoffrey Wilkinson and Ernst Otto Fischer the Nobel Prize. These organic compounds, made of a transition metal "sandwiched" ...
Medical Xpress / Microplastics discovered in prostate tumors
Small fragments of plastic were found in 9 out of 10 patients with prostate cancer, and in higher levels inside tumors than in nearby noncancerous tissue, a new study finds. The small, single-center study was led by researchers ...
Phys.org / Tomb more than 1,000 years old found in Panama
Archaeologists have discovered a tomb more than a thousand years old in Panama containing human remains alongside gold and ceramic artifacts, the lead researcher told AFP on Friday.
Tech Xplore / AI model edits can leak sensitive data via update 'fingerprints'
Artificial intelligence (AI) systems are now widely used by millions of people worldwide, as tools to source information or tackle specific tasks more rapidly and efficiently. Today, some of the most used are large language ...
Medical Xpress / Oxytocin reverses anxiety-like behavior after three months of isolation in mice
Periods of prolonged social isolation have long been associated with difficult emotions and, in some cases, with the emergence of psychiatric symptoms, such as depression, anxiety, and difficulties connecting with others. ...
Medical Xpress / Oxytocin-sensitive brain circuit may keep social bonds active under stress
The neuropeptide oxytocin is a special messenger substance that nerve cells use to communicate with each other. It is acting as both a neurotransmitter and a hormone and is best known for promoting social behavior. However, ...
Medical Xpress / Dry powder inhalers can improve patient outcomes and lower environmental impact
New research from UCLA Health suggests that certain inhalers used to treat chronic obstructive pulmonary disease (COPD) are not only less harmful to the environment but can also lead to slightly better patient outcomes. Inhalers ...
Phys.org / Can a chatbot be a co-author? AI helps crack a long-stalled gluon amplitude proof
Like many scientists, theoretical physicist Andrew Strominger was unimpressed with early attempts at probing ChatGPT, receiving clever-sounding answers that didn't stand up to scrutiny. So he was skeptical when a talented ...
Phys.org / How natural language processing and AI can help policymakers address global food insecurity
NLP offers powerful opportunities to support the UN Sustainable Development Goals (SDGs)—including SDG2 (Zero Hunger). In the wake of the COVID-19 pandemic, the Russia-Ukraine war, mounting climate change impacts, and other ...
Phys.org / The persistence of gravitational wave memory
Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two neutron stars collide, they ...
Medical Xpress / Preclinical or clinical? New obesity definition could reshape diagnosis and prevention
An international research group has examined how many people are affected by preclinical and clinical obesity and what health risks are associated with this. The team led by Prof. Matthias Schulze from the German Institute ...
Tech Xplore / Forest-based resins challenge fossil materials in wind turbines, boats and high-performance adhesives
Researchers at the University of Oulu, Finland, have developed new high-performance bio-based resins that can replace conventional oil-based materials in composite products—without compromising strength, cost, or industrial ...
