Phys.org / Can climate shocks change how people feel about paying taxes?
Climate-related disasters are becoming more frequent and more intense across sub-Saharan Africa. Floods, droughts, heat waves and storms are no longer isolated environmental events. They increasingly shape livelihoods, inequality, ...
Phys.org / Why female guppies prefer rare males and how this might shape evolution
When it comes to choosing a partner, some species prefer males that stand out from the crowd. Evolutionary biologists call the resulting process negative frequency-dependent selection. It means that a male has a huge mating ...
Phys.org / Unintended climate trade-off: Clean air policies intensify urban heat island in humid cities, study finds
Researchers at the University of Hong Kong (HKU) have uncovered a critical, underrecognized trade-off in global environmental policies: While essential for improving public health, large-scale air pollution reductions are ...
Medical Xpress / Antibiotics reverse damage caused to blood stem cells by chronic Salmonella, study suggests
A new study from Ben-Gurion University of the Negev (BGU) has revealed that long-term Salmonella infections severely damage blood stem cells—the essential factory cells in bone marrow that produce all the body's blood and ...
Medical Xpress / Medical museums often display infant remains. How they were acquired was frequently harrowing
If you've been to a museum about the history of medicine or surgery, you've probably seen loads of preserved human remains that have been used as teaching aids or in scientific research.
Medical Xpress / Scans reveal lithium distribution in bipolar disorder
A revolutionary scanning technique has revealed that lithium MRI is a powerful tool for studying how the drug interacts with the brain and could offer more personalized treatment for bipolar disorder.
Medical Xpress / Faded letters, early warnings: A new clue for aging eyes
Struggling to read more than six lines on an eye chart with fading letters may serve as a visual "yellow light" for older adults—raising red flags that routine exams sometimes fail to detect. A new University of Michigan ...
Medical Xpress / The condition that causes people to get lost in their own home
Think about the last time you used your phone to find your way somewhere. What would happen if, halfway through the journey, the route instructions vanished or your phone battery died? You might find yourself starting to ...
Medical Xpress / Family of drugs used for treating muscular dystrophy could improve brain tumor treatment
A drug from the same family licensed for use in patients with Duchenne muscular dystrophy and blood cancer could transform the treatment of meningioma—the most common form of primary brain tumor in adults. Scientists at the ...
Phys.org / Artificial DNA tiles could deliver drugs and monitor neurons non-disruptively
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
Phys.org / Lamprey brain atlas reveals 450-million-year blueprint of vertebrate brains
What did the very first complex vertebrate brain look like? To find out, scientists turned to an unlikely time traveler: the lamprey, a jawless, eel-like fish whose body plan has barely changed in roughly 360 million years.
Phys.org / White barn owls may use moonlight to startle prey
White barn owls are effective killing machines. They fly silently through the night air and swoop down on unsuspecting prey with their sharp talons. But they have something you would think goes against being a stealth predator: ...
