Phys.org / LiON: A fluorescent molecule tracks iron and oxygen levels in individual cells
A new fluorescent reporter capable of visualizing biologically active iron and oxygen inside living cells at single-cell resolution has been developed, as reported by researchers from Science Tokyo. Using this new tool, they ...
Phys.org / Intermolecular collisions may explain why organic radical fluids become unusually magnetic
Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how easily a material can be magnetized. Materials known as organic radicals have been noted to possess anomalously ...
Phys.org / Random deformation lets glassy materials store precise mechanical memories, simulations reveal
Amorphous materials such as glass are solids whose internal structure lacks a repeating pattern. Their molecules are arranged in a random and irregular way. Surprisingly, these disordered materials can "remember" past mechanical ...
Medical Xpress / Could a once-a-day pill replace weight loss injections? Phase II oral GLP-1 drug trial shows promising results
For those scared of needles but who need GLP-1 receptor agonists to help manage their weight, there might be some good news. Researchers are testing a new oral, small-molecule GLP-1 receptor agonist called Elecoglipron, which ...
Medical Xpress / Shingles vaccine may lower dementia risk, study suggests
Older adults who received a shingles vaccine after a stay in a skilled nursing facility had a 24% lower risk of being diagnosed with dementia over a four-year period than those who were not vaccinated, according to a new ...
Phys.org / Data suggest 'red flag' laws are linked to sustained reductions in arrests
Individuals subject to extreme risk protection orders (ERPOs), or "red flag" laws, were significantly less likely to be arrested—including for violent and firearm-related offenses—while the orders were in effect than in the ...
Phys.org / Your body's secret sugar code could predict disease years before it strikes
Scientists have found that hidden health signals coating your cells could change medicine forever. The new study by Edith Cowan University (ECU) School of Medical and Health Sciences has shown sugar molecules in your body ...
Medical Xpress / World's largest genetic study of 'moliness' helps unravel mysteries of melanoma
QIMR Berghofer scientists have uncovered hundreds of genes that play a role in the growth of both moles and melanoma, in a discovery that could lead to new ways of preventing and treating the deadliest form of skin cancer. ...
Phys.org / Engineering quantum Hall stripes in 2D materials inside electromagnetic cavities
Quantum materials, materials with properties that are governed by the laws of quantum mechanics, have proved to be highly promising for the development of ultra-efficient electronic devices, quantum processors, highly precise ...
Medical Xpress / Q&A: What does science say about plants as medicine?
Plants have always played an integral role in traditional medicine and healing practices, according to Kent Vrana, Elliot S. Vesell Professor of Pharmacology at Penn State College of Medicine, and they continue to shape health ...
Medical Xpress / Psychologists shouldn't replace thinking with AI, researchers warn
For some psychologists, it's becoming more common to use AI systems to replace human thinking in research. That's a very risky choice based on misconceptions, warn Iris van Rooij and Olivia Guest in a new paper published ...
Medical Xpress / Copper drug restores memory and clears toxic Alzheimer's proteins, preclinical study finds
Monash University researchers have found in laboratory experiments that a drug that delivers copper to the brain significantly reduces toxic Alzheimer's proteins and improves long-term spatial memory.
