Medical Xpress / World's only deuterium-labeled guinea pig helps scientists study metabolism
A Skoltech scientist has raised the world's only isotope-labeled guinea pig. For 156 days, the animal, named Khryun, was given only heavy water to drink. Such water is non-radioactive and has long been used in biomedical ...
Phys.org / Mining a methane-degrading bioreactor for protein rubies
Scientists have found a new type of iron-storing protein in a mixture of microbes containing methane-degraders. This discovery underscores the importance of characterizing proteins from microbes that cannot be isolated, thereby ...
Phys.org / Hydrogen shell detected around Nova Persei 1901 may be a planetary nebula
Using NASA's SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, they detected a bipolar molecular hydrogen shell around this nova, which may be a large planetary ...
Medical Xpress / Scientists uncover key 'lipid transporter' that keeps skin healthy
Scientists have identified the transporter protein that allows essential fats in the bloodstream to enter the skin, reshaping understanding of how the skin maintains its protective barrier.
Tech Xplore / 'Neuron-freezing' technique can stop LLMs from giving users unsafe responses
Researchers have identified key components in large language models (LLMs) that play a critical role in ensuring these AI systems provide safe responses to user queries. The researchers used these insights to develop and ...
Phys.org / Tracking Arctic freshwater flow from space
Arctic rivers wind through remote tundra and boreal forests, freezing solid in winter and surging each spring with snowmelt, eventually emptying into the ocean. Runoff—water that does not soak into the ground but instead ...
Medical Xpress / Scientists pinpoint a skin alarm system pathway that links local damage to systemic immune responses
Skin, our largest organ, acts as a protective barrier against pathogens that try to invade our bodies while constantly monitoring for potential threats. In the skin's outermost layer, the epidermis, reside keratinocytes, ...
Phys.org / Did you hear the one about scientists telling jokes? Not many did, according to a study of humor at conferences
To engage audiences and help keep their attention, many public speakers sprinkle their speeches with a little humor. It's a useful tool, but something that scientists rarely use, according to a report into humor at science ...
Tech Xplore / Insect-inspired robot tracks odors even with only one working 'antenna'
A collaborative research group has developed a bio-inspired robotic system based on insect behavior which can locate odor sources both indoors and outdoors with consistent accuracy, even if one of its two sensors fails. The ...
Phys.org / How dolphins communicate: New discoveries from a long‑term study in Sarasota, Florida
Human fascination with bottlenose dolphins goes back thousands of years, at least as early as Greek mythology.
Medical Xpress / Exploring balance recovery in people with and without Parkinson's disease
In a study published in eNeuro, Lena Ting, from Emory University, and colleagues explored how brain and muscle activity during balance recovery change due to aging and Parkinson's. Previously, Ting's research group revealed ...
Tech Xplore / Radiation‑hardened Wi‑Fi chip survives 500 kGy for nuclear plant decommissioning robots
When a nuclear plant reaches the end of its life or is damaged, it must be decommissioned. This process can take more than 20 years and includes decontamination, dismantling, and handling radioactive materials so the site ...
