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.
Medical Xpress / Reversing immune suppression in pancreatic cancer could lead to novel therapies
In a unique finding, researchers at Georgetown's Lombardi Comprehensive Cancer Center discovered that when pancreatic cancer cells send out tiny particles that are packed with certain microRNA molecules, nearby immune cells ...
Phys.org / Slowing down muon decay with short laser pulses
Muons are unstable subatomic particles that spontaneously and rapidly transform into other particles via a process known as electroweak decay. Altering the speed with which muons decay into other particles was so far deemed ...
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 / Temporal anti-parity–time symmetry offers new way to steer energy through systems
The movement of waves, patterns that carry sound, light or heat, through materials has been widely studied by physicists, as it has implications for the development of numerous modern technologies. In several materials, the ...
Phys.org / Sharks are famous for fearsome teeth, but ocean acidification could make them weaker
Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.
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 ...
Phys.org / Revealing the cell's nanocourier at work
An international group of researchers led by Pompeu Fabra University has discovered the nanomachine that controls constitutive exocytosis: the uninterrupted delivery of spherical molecular packages to the cell surface. This ...
Phys.org / Cells use dual strategies to fine-tune inflammatory gene activation
Inflammation has to fight pathogens fast—but it can't get out of control. Researchers at the German Cancer Research Center (DKFZ) have now deciphered in more detail how the organism masters this balancing act. Their work ...
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.
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 / How actin wavefronts rescue T cell receptors from endocytosis
Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play. T cells, the top agents in this system, survey the internal environment of infected cells and ...
