Phys.org / Sideways discovery rewrites the rules of antigen presentation
A new discovery about how cells communicate with each other in the body's immune system has revealed deeper insights for an international team of scientists into fundamental immune system function.
Medical Xpress / Ion channel offers promising avenue for new Parkinson's drugs
Lysosomes are the recycling centers of human cells. Larger molecules are broken down inside the membrane-enclosed vesicles. Malfunctions can lead to neurodegenerative diseases such as Parkinson's.
Phys.org / Astronomer uses 'China Sky Eye' to reveal binary origin of fast radio bursts
An international team of astronomers, including researchers from the Department of Physics at The University of Hong Kong (HKU), has uncovered the first decisive evidence that at least some fast radio burst (FRB) sources—brief ...
Phys.org / Exploring mutations that spontaneously switch on a key brain cell receptor
Many people are familiar with histamine, a biological molecule that serves as a key driver of allergic reactions and other immune responses. However, histamine is also a major neurotransmitter in the mammalian brain, regulating ...
Phys.org / When tropical oceans were oxygen oases
Research reveals when and why ancient tropical seas transitioned from oxygen oases to marine dead zones, providing clues to the long-term evolution of oceanic environments.
Phys.org / Chiral nanowires can actively change electron spin direction
The phenomenon where electron spins align in a specific direction after passing through chiral materials is a cornerstone for future spin-based electronics. Yet, the precise process behind this effect has remained a mystery—until ...
Medical Xpress / Super agers tend to have at least two key genetic advantages, study finds
The gene variant posing the greatest genetic risk of late-onset Alzheimer's disease (AD) is called APOE-ε4. A different variant of the same gene, APOE-ε2, is thought to confer protection against AD.
Phys.org / When employees feel slighted, they work less, research reveals
A missed birthday. A forgotten anniversary. A milestone that goes unnoticed. These small slights from a manager may seem like no big deal, but new research from Wharton reveals that even the mildest of mistreatment at work ...
Medical Xpress / 1 in 5 people say losing their pet was worse than losing a person
For one in five people, losing a pet has been more distressing than losing a human loved one. New research has revealed that 21% of those who experienced both types of bereavement found their pet's death harder to bear.
Phys.org / Biomass-derived furans offer sustainable alternative to petroleum in chemical production
A research project conducted by the Max-Planck-Institut für Kohlenforschung shows how biomass can be used as a raw material for chemical products instead of petroleum. The scientists have published their findings in the ...
Medical Xpress / Decline in U.S. nursing home capacity since COVID-19: Rural areas hit hardest
Though the U.S. population is aging, nursing home capacity has declined nationwide since the COVID-19 pandemic began. According to a study published in JAMA Internal Medicine this week, one quarter of U.S. counties experienced ...
Medical Xpress / Scientists discover natural 'brake' that could stop harmful inflammation
Researchers at University College London (UCL) have uncovered a key mechanism that helps the body switch off inflammation—a breakthrough that could lead to new treatments for chronic diseases affecting millions worldwide.
