Dialog / Why do some stars in the galactic center survive while others are destroyed?
The center of our galaxy is an extreme place. Surrounding the supermassive black hole Sagittarius A*, stars are packed densely into a region where gravity, radiation, and dark matter all interact in complex ways. It is a ...
Medical Xpress / Fluoride and kids' IQ: What a decades-long analysis shows
Fluoride is a naturally occurring mineral that has been shown to strengthen teeth and reduce cavities. Many municipalities add fluoride to their drinking water—a process called community water fluoridation—as a public health ...
Medical Xpress / The term 'alcoholic' conjures outdated stereotypes about an illness that afflicts 28 million Americans, says expert
People just aren't drinking the way they used to. "As recently as the late 1990s or early 2000s, 85% or more of high school seniors said they drank in the past year. Now that number is down to about 42%," said Kathryn McHugh, ...
Phys.org / Mount Etna breaks volcano rules, tapping 80-kilometer-deep magma in a rare fourth category of eruption
Located in Sicily, Mount Etna is Europe's most active volcano. Yet its origin remains largely enigmatic, as no existing geological model fully explains how it formed. In a new study, scientists from the University of Lausanne ...
Phys.org / Plants use a protein-tagging complex to control stress survival, study finds
A specific cellular mechanism regulates the protein balance of plants, thereby influencing how they respond to environmental stress. An international research team led by Dr. Markus Wirtz at the Center for Organismal Studies ...
Phys.org / Tiny crystal defects solve decades-old mystery in organic light emitters
Materials that emit and manipulate light are at the heart of technologies ranging from solar energy to advanced imaging systems. But even in well-studied materials, some fundamental behaviors remain unexplained. Researchers ...
Medical Xpress / Neuroinflammation triggers autism-like regression in mouse model
Autism spectrum disorder (ASD) is a neurodevelopmental condition estimated to affect approximately 1 in 100 children worldwide. This condition is characterized by differences in how people communicate and interact with others, ...
Phys.org / Designing better membrane proteins by embracing imperfection
Scientists at the VIB–VUB Center for Structural Biology have uncovered a counterintuitive principle that could reshape how membrane proteins are designed from scratch: Sometimes, making a protein less stable helps it fold ...
Medical Xpress / Pain-sensing neurons mapped in unprecedented detail, pointing to new chronic pain drug targets
One in five people worldwide suffers from chronic inflammatory pain. Meanwhile, about two thirds of those affected find little relief from existing pain medications; new therapeutic approaches are urgently needed. "We first ...
Phys.org / When the boss burns out, the whole team loses energy, trust and performance
The well-being of a supervisor is reflected through supervisor-subordinate relationships in employee motivation and performance, and consequently, in the company's competitiveness. In his doctoral research at the University ...
Phys.org / New research on cellular redox reactions sheds light on the path of neurodegenerative diseases
The mechanics of the onset of cancer or neurodegenerative disorders like Alzheimer's disease or ALS remain a mystery. Scientists associate these diseases with an increase in unstable molecules called reactive oxygen species ...
Phys.org / Beneath this cemetery, 5.5 million wild bees form a giant underground city vital to spring pollination
To save money, Rachel Fordyce parked her car for free at Ithaca's East Hill Plaza and walked through East Lawn Cemetery to her job as a technician in an entomology lab on Cornell's campus. One spring day in 2022, she walked ...
