Phys.org / Bumblebees can learn to associate new smells with their queen
Bumblebees are able to learn to associate new odors with their colony's queen, instead of being preprogrammed to recognize the queen's pheromones from birth, according to a new study led by researchers at Penn State. For ...
Phys.org / Rivers are moving sediment in intense bursts, a worrisome new pattern uncovered by AI
After a heavy rain, rivers often turn brown with sediment, sand, silt and soil washed from the landscape that play a vital role in shaping rivers.
Phys.org / DNA repair enzymes favor specific sequences, shaping mutation patterns in the human genome
When a wound does not heal properly, it leaves a scar. Similarly, mutations—which are permanent changes to genetic code—are often the result of damaged DNA that has not been properly repaired. Mutations can impede the function ...
Phys.org / Illegal fishing captures up to 15% of global marine wild catch, analysis finds
Industrial-scale illegal fishing continues to undermine ocean sustainability, coastal livelihoods and global seafood markets—despite decades of regulation and recent advances in surveillance technology, according to new University ...
Phys.org / Oral nanomedicine improves cancer immunotherapy by harnessing gut bacterial metabolite
A joint research team—led by professor Young Seok Cho from the School of Medicine, alongside professor James J. Moon from the University of Michigan—has developed the world's first oral, microbiome-based nanomedicine. By ...
Phys.org / Egyptian blue in Iron Age Iran points to ancient connections
Egyptian blue, considered the world's earliest synthetic pigment, was prized for its stable blue hues and served as a common blue paint in Egypt as early as 5,000 years ago, as well as the base material for small items such ...
Medical Xpress / Scientists uncover cellular mechanism driving both rare childhood dementia and Alzheimer's disease
Researchers at the University of California San Diego and their colleagues have identified a key cellular pathway that drives brain degeneration in both a rare childhood disorder and the far more common Alzheimer's disease. ...
Phys.org / Oak leaves harbor distinct microbial worlds on their opposite surfaces
A single leaf may look like a simple patch of green, but to the microscopic life that inhabits it, it is a vast landscape divided into different worlds.
Phys.org / Himalayan grain demonstrates the potential of pangenome-guided breeding for higher yields and adaptability
Scientists from the Centre for Crop and Food Innovation (CCFI) at Murdoch University have participated in a landmark proof-of-concept research project demonstrating how pangenome-guided breeding strategies can reunite two ...
Phys.org / Chinese label once tied to Boston Tea Party reveals 19th-century Pacific trade
When MIT historian Tristan Brown first examined a Chinese tea chest label displayed as a relic of the Boston Tea Party, he had no reason to doubt its story.
Medical Xpress / Mapping how mental health risks emerge in AI chatbot conversations
Scientists at UCL have developed a framework for stress-testing how AI chatbots respond to vulnerable users, helping researchers identify weaknesses and test ways to make mental health interactions safer.
Phys.org / Rescued platypuses quickly return to normal lives after five months in captivity
Platypuses rescued during a severe drought quickly returned to their old routines after being released back into the wild, suggesting emergency rescues can help protect vulnerable populations.
