Medical Xpress / BMI alone does not fully capture health risks linked to obesity, new study finds
Obesity is commonly diagnosed using BMI, but this approach has several limitations. Researchers at Lund University and AstraZeneca show that integrating measurements such as body fat percentage and waist circumference captures ...
Tech Xplore / Data centers raise nearby temperatures by up to 4 degrees in Phoenix
Waste heat from data centers can boost air temperatures in downwind neighborhoods by as much as 4 degrees Fahrenheit, researchers at Arizona State University report in a new study conducted in the Phoenix metro area, the ...
Phys.org / AI-generated fake citations are flooding scientific literature across publications, scientists warn
The citations at the end of a research paper should represent a solid foundation of existing knowledge about a particular field, a pool of peer-reviewed sources built over years of research and study. However, with the increasing ...
Phys.org / Silver vine or catnip? When cats can choose, silver vine wins
What plant do cats love most? In Europe and North America, many people would probably answer "catnip." In Japan, the answer would more likely be silver vine (matatabi in Japanese). Both plants are famous for triggering the ...
Phys.org / Molecular net boosts the power of natural biopesticides
Scientists at VIB and Vrije Universiteit Brussel have uncovered a previously unknown mechanism that helps a widely used biological pesticide become more effective. The study, published in Nature Communications, reveals how ...
Phys.org / Grokipedia selectively draws on more-right leaning news sources, says new study
A large-scale analysis of Grokipedia, the world's first AI-written encyclopedia, has found that while many Grokipedia articles closely resemble their Wikipedia counterparts, a substantial subset diverged markedly in style, ...
Phys.org / Debunking a core chemistry concept taught in classrooms everywhere
A new study has revealed that a core idea taught in chemistry classrooms around the world may be wrong. Dr. Edwin Johnson, Lecturer at the University of Newcastle, co-authored the paper published in the Journal of Chemical ...
Tech Xplore / Toward power-generating displays: A single device that harvests and emits light
A newly developed organic semiconductor device can both generate electricity from light and emit bright visible light, as reported by researchers from Science Tokyo. By carefully designing a material where energy losses are ...
Medical Xpress / Why brain cells learn better: NMDA receptor maps may explain memory-linked calcium flow
The human brain constantly adapts in response to experiences, forming new connections between neurons and reorganizing existing ones. The brain's ability to adapt in response to experiences is known as neuroplasticity.
Phys.org / Proteins that create ice inspire 'cool' applications, from cryomedicine to artificial snow
Bacteria from the Middle East have caused precipitation all the way out in California. The same bacteria, which are known to attack plants, have also been found embedded within lumps of hail in West Africa.
Tech Xplore / Solar power leaves land behind as floating systems gain ground
The effects of global warming are becoming increasingly evident and catastrophic. To prevent irreversible consequences, international scientific consensus emphasizes the importance of mitigating climate change in ways that ...
Phys.org / Decoding the balance between life-and-death proteins
In every organism, the regulation of cell populations is a constant process. This balance relies on a continuous interplay between "guardian" proteins that promote cell survival and "killer" proteins that trigger programmed ...
