Tech Xplore / Major security weaknesses found in leading open-weight LLMs
Safety protections built into some of the world's most widely used artificial intelligence (AI) models can be stripped away with alarming ease, according to a new international study.
Medical Xpress / AI helps identify regulatory hub for aging in hematopoietic stem cells
Stem cells possess the unique ability to self-renew and transform into different types of cells. For example, rare hematopoietic stem cells found in bone marrow can become any type of blood cell. Throughout life, they can ...
Medical Xpress / First evidence of mirror-like activity found in individual human neurons
In the early 1990s, researchers studying nonhuman primates discovered a population of brain cells they called "mirror neurons." These specialized brain cells fired when the animal performed an action and also when the animal ...
Phys.org / Listening for extinction: Study finds areas of critical concern for northern spotted owls
Northern spotted owl populations are approaching or have already crossed functional extinction across large areas of the Pacific Northwest, a new study, published in Ecological Applications found. Researchers used artificial ...
Dialog / Could we protect all western US communities from wildfires and facilitate restoring fire to wildlands within a decade?
In a new study in Environmental Research: Ecology, I analyzed how fires were able to burn into communities and how fire-resistant land uses could be combined with fuel treatments to reduce fires burning into communities. ...
Tech Xplore / Information encoded in a beam of light can survive real-world atmospheric turbulence
Researchers at the University of the Witwatersrand (Wits) and the University of Bordeaux in France have demonstrated a new way to send information through the atmosphere without correcting for the distortions that normally ...
Medical Xpress / Nicotine e-cigarettes help four more people per 100 quit than patches or gum
Nicotine e-cigarettes are more effective at helping people quit smoking than many conventional methods, including nicotine gum and patches, behavioral support or no support at all, an updated Cochrane review finds.
Medical Xpress / Additional transfusion risk emerges for patients with tick-borne alpha-gal syndrome, beyond meat allergy
A new multi-institutional study led by researchers at Dartmouth Health and Geisel School of Medicine at Dartmouth suggests that alpha-gal syndrome, a tick-borne disease that can result in a chronic allergy to meat and animal ...
Phys.org / Four ζ-carotene isomers reveal light-driven shifts and skin-protective potential
ζ-Carotene, a key intermediate in lycopene biosynthesis, is widely found in plants and photosynthetic microorganisms, but its isomer-specific properties remain poorly understood due to isolation and purification challenges. ...
Phys.org / A tiny drop of water is all that's needed to find threatened frogs
New James Cook University research has used highly sensitive environmental DNA (e-DNA) techniques to find two species of threatened frogs in places they've never been seen before—and find another still struggling to recover ...
Medical Xpress / Mucus-coated tumor spheres reveal potential targets to curb colorectal cancer spread
Researchers from the University of Turku in Finland and Gustave Roussy Institute in France have discovered a molecular mechanism that regulates whether cells in an aggressive colorectal cancer are conventional or inverted ...
Phys.org / Cow gut enzyme could help target bacterial biofilms and antibiotic-resistant infections
The bacterium Acinetobacter baumannii poses a substantial threat in health care settings, readily forming biofilms on wounds and medical surfaces and contributing to persistent infections and delayed healing. Its growing ...
