Phys.org / Human impacts rewrite the rules of island biodiversity around the globe
A new study reveals that human activities have fundamentally reshaped biodiversity patterns on islands across the globe, with important implications for how scientists understand ecology, evolution and conservation.
Tech Xplore / Hidden prompts can plant false memories in AI agents, researchers warn
Large language models (LLMs), the computational algorithms underpinning ChatGPT, Gemini and other artificial intelligence (AI)-powered conversational platforms, are now widely used worldwide. These models can rapidly answer ...
Phys.org / Spent coffee grounds reveal a route to biodiesel and other bio-based products
Coffee grounds that usually end up being thrown away can have a second life as a raw material for producing biofuels and other high-value-added products. A study by the Universitat Rovira i Virgili (URV) has evaluated how ...
Medical Xpress / Frequent cannabis users wake with higher cortisol levels, study finds
Research suggests people who often use cannabis start their day with higher cortisol levels than people who don't, indicating a relationship between frequent cannabis use and a possible dysregulation of the body's daily stress ...
Phys.org / Universal structure of exceptional points revealed in nonlinear light‑based systems
Exceptional points, or EPs for short, are among the phenomena of modern physics. These are special points or locations at which the properties of matter, space or time change. In a new theoretical study, researchers from ...
Phys.org / Destructive crop caterpillar harbors fungi that can degrade Styrofoam
A moth caterpillar identified by the agribusiness sector as one of the most destructive pests of soybean, cotton and corn crops may harbor fungi and bacteria in its gut that can degrade expanded polystyrene, also known as ...
Phys.org / Earlier toilet training could curb growing diaper waste crisis
Earlier toilet training and new recycling technologies are among expert-backed solutions to reduce the environmental impact of disposable diapers and other hygiene products, according to a new study led by UCL researchers.
Phys.org / Jupiter-mass 'exomoon' orbiting brown dwarf challenges cosmic labels
Observations made with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed evidence for a moon-like object in the CD-35 2722 system. Unlike moons in our solar system, the newly found object ...
Phys.org / Observations investigate the nature of a peculiar supernova
An international team of astronomers has performed follow-up observations of a peculiar Type Ia supernova designated SN 2023vjh. Results of the observational campaign, published July 9 on the preprint server arXiv, deliver ...
Medical Xpress / Natural clotting 'switch' may one day reduce reliance on blood thinners to prevent heart attacks and strokes
Cardiovascular conditions such as strokes or heart attacks are among the most common causes of death in Germany. Today, treatment and prevention are primarily based on so-called platelet aggregation inhibitors and anticoagulants—types ...
Phys.org / National food waste recycling promises major climate gains but comes with microplastic risks
Keeping food waste out of landfills provides climate and other environmental benefits, and Vermont requires residents to divert these materials to better management pathways. With other states considering similar policies, ...
Phys.org / 'Jimothy' the raccoon has short spine syndrome—but this condition can affect dogs, too
If you've been anywhere near the internet in recent days, you will likely have seen the viral footage of "Jimothy": an unusually round raccoon in Seattle that hops and skips along in a video filmed by local resident Kiana ...
