Phys.org / This nasal spray rewinds the aging brain, restoring memory and reversing inflammation in preclinical models
Picture this: your brain is a high-performance engine. Over decades, it doesn't just wear down, it also starts to run hot. Tiny "fires" of inflammation smolder deep within the brain's memory center, creating a persistent ...
Phys.org / Weighing in on the mystery of the gravitational constant
The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and Technology (NIST), wasn't sure he wanted to know the secret number that lay inside. For the past 10 ...
Phys.org / Navigating the past with ancient stone compass needles
Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small samples of rocks, scientists can isolate magnetic grains that were frozen in orientation as the rock ...
Phys.org / The moon might be more prone to fires
Engineers love a good practical challenge, especially when it comes to spaceflight. But there's one particular challenge facing the crewed missions of the near future that scares mission planners above almost all others—fire. ...
Phys.org / Surprising link between metallicity and superconductivity uncovered in twisted trilayer graphene
Superconductivity is a state of matter characterized by an electrical resistance of zero, typically at very low temperatures. Past studies have found that in various materials, this unique state is accompanied by unusual ...
Phys.org / Universal quantum protocol extracts maximum work without knowing a system's state in advance
A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work from many copies of a quantum system does not require knowing exactly what state that system is in.
Phys.org / How poison frogs built a chemical weapons system one evolutionary step at a time
Poison frogs are small and brightly colored amphibians that originate from Central and South America. As suggested by their name, these frogs can release highly toxic chemicals from their skin, which deter and neutralize ...
Tech Xplore / Perovskite solar cells reach 26.61% certified efficiency with cesium-doping strategy
Solar cells, devices that convert sunlight into electricity, are now widely used in many countries. While most existing solar cells are based on silicon, energy engineers have been working on other devices made of so-called ...
Phys.org / Looking deep inside quarks: CMS test probes to 10⁻²⁰ meters and finds no inner structure
According to our current understanding of the universe, quarks are fundamental, point-like particles: basic building blocks that are not made up of smaller particles. A recent paper from the CMS Collaboration describes how ...
Phys.org / America's sewage and manure hold a $5.7 billion key to breaking synthetic fertilizer dependence
Nutrients recovered from animal and human waste could drastically reduce synthetic fertilizer use in the U.S., according to a new Cornell University study that takes into account real-world implementation challenges like ...
Phys.org / Dark matter could explain the earliest supermassive black holes
A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing less than a billion years after the Big Bang. According to the standard theory of black hole formation, ...
Phys.org / Are aliens real? Scientists have been hunting for extraterrestrial life since the time of Aristotle
Do aliens exist? Could Earth really be the only planet hosting intelligent life?
