Medical Xpress / Stimulating mitochondria to boost long-term memory
An international team led by Jaime de Juan-Sanz at the Paris Brain Institute has shown that slightly increasing the metabolic capacity of neurons can enhance long-term memory in both fruit flies and mice. The study, published ...
Phys.org / How many bee species exist? New global count puts the total near 26,000
The world has far more bees than anyone realized. Scientists have, for the first time, estimated just how many species of bees are out there on a global scale, offering a clearer look at how these vital pollinators are distributed ...
Phys.org / New lab technique can reverse chemical process linked with Alzheimer's disease
An Oregon State University scientist and a team of undergraduate students have uncovered real-time insights into a chemical process linked with Alzheimer's disease, paving the way toward better drug designs. The researchers ...
Phys.org / Enzymes work as 'Maxwell's demon' by using memory stored as motion
Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and function. Enzymes play a central role in this process, accelerating reactions that would otherwise ...
Phys.org / Methane's missing emissions: The underestimated impact of small sources
Methane is a potent greenhouse gas, with an impact estimated at 80 times that of CO₂. Although efforts are being made to reduce the contribution of big polluters to methane in Japan, new research from Osaka Metropolitan ...
Medical Xpress / Did you hear about the lab-made ear?
In laboratory experiments, researchers have produced ear cartilage that remains form-stable in animal models. Only one element is missing to make the tissue as elastic as a natural ear.
Phys.org / Cannabis essential oils unlock how camphor repels mosquitoes
From summer evenings to global disease prevention, mosquito repellents are a daily defense for billions of people, yet until now, scientists didn't fully understand how mosquitoes themselves perceive these "keep away" signals. ...
Phys.org / Chemists thought phosphorus had shown all its cards—until it surprised them with a new move
A discovery by UCLA organic chemists may one day put catalytic converter thieves out of business. In new research, they've used abundant, inexpensive phosphorus as a catalyst in chemical reactions that usually require precious ...
Medical Xpress / Engineered immune therapy could help fight brain aging
Researchers with the Knight Initiative for Brain Resilience have modified a well-known immune protein to spark the growth of new neurons, ease brain inflammation, and improve cognition in old mice. The findings, published ...
Phys.org / Ribosome could have emerged from ancient antagonism between parasites and proto-cells
Ribosomes are the components of cells that read RNA and build proteins. Without the ribosome, the chemistry of life would still be catalyzed by raw RNA. And yet the origin of the ribosome remains a mystery. In a Perspective ...
Tech Xplore / How can you avoid AI sycophancy? Keep it professional, researchers say
Drawing boundaries isn't just important for relationships with humans anymore. It could be the key to people's relationships with their favorite AI chatbots. Researchers recently discovered that the overly agreeable behavior ...
Phys.org / Diamond surfaces are covered in thin, ice-like water layers
Using atomic-scale defects in diamond, researchers in China have gained unprecedented insights into the complex chemical processes that unfold at the interfaces between solid surfaces and their surroundings. Published in ...
