Medical Xpress / Consuming 2–3 cups of coffee daily associated with lower dementia risk, better cognitive function
A new prospective cohort study by investigators from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute of MIT and Harvard analyzed 131,821 participants from the Nurses' Health Study ...
Phys.org / People act more helpfully in poor environments than rich ones, research reveals
People are more likely to act helpfully in situations where there are poorer choices to give to others, according to a new study that tested willingness to help others in different contexts.
Phys.org / Muon Knight shift reveals the behavior of superconducting electron pairs
Quantum materials and superconductors are difficult enough to understand on their own. Unconventional superconductors, which cannot be explained within the framework of standard theory, take the enigma to an entirely new ...
Phys.org / Deep-sea microbes get unexpected energy boost from marine snow, researchers discover
For many years, the deep ocean has been seen as a nutrient-poor environment where microbes living in the water survive on very limited resources. But new research from the University of Southern Denmark (SDU) challenges that ...
Phys.org / Physicists clarify key mechanism behind energy release in molybdenum-93
A team of physicists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences, together with collaborators, has identified the dominant physical mechanism responsible for energy release in the nuclear ...
Medical Xpress / Study of 12 monks finds meditation heightens brain activity, reshaping neural dynamics
Contrary to popular belief, meditation isn't "thinking about nothing." In fact, a new international study on Buddhist monks shows that meditation is a state of heightened cerebral activity in which brain dynamics are profoundly ...
Phys.org / Seeing the whole from a part: Revealing hidden turbulent structures from limited observations and equations
The irregular, swirling motion of fluids we call turbulence can be found everywhere, from stirring in a teacup to currents in the planetary atmosphere. This phenomenon is governed by the Navier-Stokes equations—a set of ...
Phys.org / How big can a planet be? With very large gas giants, it can be hard to tell
Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't have hard surfaces. Jupiter and Saturn are the gas giants in our solar system, but there are many ...
Phys.org / Why does rough grinding make stainless steel more prone to corrosion?
Stainless steel is widely known for its impressive corrosion resistance, but it is not invincible. When exposed to environments containing chloride ions, such as seawater, the risk of corrosion increases. To achieve the sleek, ...
Phys.org / Why elite chess ratings get stuck: A new model treats draws as data
Here's a statistical challenge worthy of a grandmaster: How do you create an accurate ranking system when the best players usually don't win? This is the conundrum of elite chess. The stronger the players, the greater the ...
Phys.org / How the spring thaw influences arsenic levels in lakes
From 1948 to 1953, a gold mine called Giant Mine released about 5 tons of arsenic trioxide per day into the environment around Yellowknife, Northwest Territories, Canada. Emissions declined from the 1950s until the mine closed ...
Phys.org / Capturing the instant of electrical switching to pave the way for faster memory
As artificial intelligence advances, computers demand faster and more efficient memory. The key to ultra-high-speed, low-power semiconductors lies in the "switching" principle—the mechanism by which memory materials turn ...
