Having normal blood pressure, no diabetes and not smoking between ages 45 and 65 is associated with nearly 13 additional years of dementia-free life, on average, a new study shows. Led by NYU Langone Health researchers, the ...

Two organisms inhabiting a common environment can sometimes mutually influence each other, either benefiting or, in some cases, damaging one another. This mutually beneficial or ambivalent biological relationship is known ...

Using spectral data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have gained some of the clearest evidence yet that white dwarf stars are accreting debris from disintegrating exoplanets. Captured while ...

Lithium-ion batteries are the leading choice in today's electric vehicle and battery energy storage system industries, but they contain a number of critical minerals—including lithium, cobalt, nickel and graphite—that are ...

Topological photonics can force propagating light to travel in a single direction—allowing researchers to route optical signals around corners and past defects without any of it scattering backward. So far, however, this ...

Personality traits have long been seen as set in stone, with many believing they stop changing once we reach adulthood. A recent study, however, challenges this long-held belief, suggesting that personality changes far more ...

For decades, scientists have asserted that the leakage of warm, salty Indian Ocean water south of South Africa into the Atlantic is a major contributor to the Atlantic Meridional Overturning Circulation (AMOC), a component ...

For archaeologists, the Coëby cemetery in Brittany, France, is a gold mine for research. It contains several prehistoric stone monuments and earth mounds. In a new study of two unusually large mounds, scientists may have ...

Scientists at Los Alamos National Laboratory have demonstrated a new quantum-dot mechanism that could significantly expand the reach of light-driven chemistry. By introducing magnetic manganese dopants into semiconductor ...

In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn't matter (3 + 2 is the same as 2 + 3, and it doesn't matter which sock goes on first). ...

Ancient Rome's greatest threat to food security wasn't the weather but the challenge of getting grain to the capital, according to a new study. By comparing hundreds of years of historical records with reconstructions of ...

Semiconductor spin qubits are one of the most promising building blocks for future quantum computers, but turning them into a working, large-scale quantum computer has so far proven difficult. For now, two big questions remain ...
