Phys.org / Molecular orbitals imaged in 3D, opening path to femtosecond videos
One of the most famous and intriguing results of quantum mechanics is the finding that fundamental particles, such as electrons, cannot be pinned down to one single location. Instead, a particle is described by its "wavefunction," ...
Phys.org / Electric field reverses phonon chirality and spin direction in ferroelectric crystal
Chiral phonons are groups of atoms that move in a circular direction when excited by an energy source, such as heat. As the phonons move through a material, they propagate that circular motion, or angular momentum, through ...
Medical Xpress / Severe COVID-19 reactivates dormant viruses, study finds
Chronically infecting viruses—such as Epstein-Barr virus, cytomegalovirus (CMV) and herpesviruses—are common and often innocuous and asymptomatic. However, emerging evidence suggests their reactivation may contribute to autoimmune ...
Medical Xpress / FLT3 inhibitors trigger ferroptosis, exposing new weakness in acute myeloid leukemia
A study published in Nature Cell Biology reports a new vulnerability in acute myeloid leukemia (AML) that might lead to novel therapies to treat the cancer while minimizing harm to normal cells. Researchers at Baylor College ...
Phys.org / Experimental drug turns cancer's favorite fuel against it
Cancer cells have a voracious appetite for sugar—using it to fuel their rapid growth. This is why many scientists have tried to develop drugs that block cancer cells' metabolism by cutting off their sugar supply.
Medical Xpress / Medicaid work rule leaves homeless people in the cold
In the spring, the federal government finalized regulations requiring millions of people who receive Medicaid benefits to prove they're working, volunteering or going to school to keep their coverage.
Medical Xpress / Mental health workers may hold negative beliefs about people who misuse opioids
A new study from the University of Georgia suggests that mental health workers may hold the harshest views toward the very patient population they're supposed to help: people with opioid addiction.
Phys.org / Little-known protein helps the body restrain scar-forming signals
U.K. and U.S. scientists have uncovered an important piece of the puzzle in the signaling pathway that causes damaging scar tissue to build up in the body, raising hopes for future treatments. A team from the University of ...
Tech Xplore / These 3D-printed objects can tell you if they're being used properly
Imagine a bottle of hazardous chemicals sitting on a laboratory shelf that changes its appearance to alert scientists that its lid is not properly secured, potentially preventing a dangerous spill.
Medical Xpress / A 'molecular switch' that heals the gut—and that colorectal cancer hijacks to spread
Digestion is hard on the cells that line the human gut, and they are constantly being shed and replaced. This renewal is driven by a population of tireless stem cells. These stem cells can both replace the various types of ...
Tech Xplore / Meta says its AI model hacked another company, adding to worries about bots going rogue
Meta said Thursday that one of its artificial intelligence models accessed the internet on its own and hacked another company, the latest in a series of disclosures about AI models going rogue.
Medical Xpress / Researchers discover immune 'off switch' used by cancer cells
Mayo Clinic researchers have identified a protein that cancer cells use to shut down the body's immune response, a discovery that could help scientists develop new treatments that make cancer immunotherapies more effective.
