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 / Soft outlet placed beneath the skin could help recharge implanted devices
Implanted medical devices are instruments placed surgically in the body. Many are battery-powered or can be wirelessly recharged. While they can be lifesavers, they are not without problems. They can run out of battery power, ...
Medical Xpress / Can AI chatbots make mental health worse? Study identifies five risky patterns
The use of generative AI has become so widespread that ChatGPT is gradually becoming a verb, much like Google and Photoshop. Hundreds of millions of people now use large language model (LLM)-based chatbots for advice on personal, ...
Tech Xplore / Elephant-inspired cement tiles cool buildings without electricity
Inspired by the cracked, water-trapping skin of elephants, Penn researchers have developed a low-cost cement tile that cools buildings by capturing and slowly evaporating water—turning a structural flaw into a climate solution.
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 ...
Medical Xpress / Gut microbiome reveals molecular clues to how quickly our bodies age
Researchers at the University of Hawaiʻi at Mānoa have found that certain gut bacteria are linked to how quickly the body ages, providing new insight into the connection between the gut, health and longevity.
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 / Hydrogel electrode improves stability of insect-based odor sensors for drones
Drones are increasingly being used for disaster response, infrastructure inspection and environmental monitoring. However, most drone systems rely primarily on cameras and other visual sensors, which can become ineffective ...
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.
Phys.org / Why a tiny social media post has mathematicians rethinking AI
As millions of people were coming down from the excitement of the FIFA World Cup final at the start of this week, a different kind of excitement was building within the mathematical community. Levent Alpöge, a mathematician ...
Phys.org / Transmissible cancer cells discovered in fish act more like parasites than traditional tumors
A team of Vermont researchers has discovered that mysterious black skin lesions afflicting catfish in Lake Memphremagog and other New England and Canadian lakes are caused by a transmissible cancer—the first identified in ...
Phys.org / Training microbes to prepare soils for the impacts of climate change
Scientists at the University of Lincoln have discovered a promising new way to help protect crops from one of climate change's growing threats to global food production—increasing soil salinity.
