Five‑metal alloy: Scientists create ultra‑stable catalyst for fuel cells
Hydrogen-powered cars, power stations and portable chargers all rely on fuel cells. At the heart of each fuel cell is a catalyst that speeds up the reaction between hydrogen and o…
Discontinuity and disorder: Explaining the luminosity bump in evolved stars
Toward the end of their lives, low-mass stars undergo an abrupt dip in brightness, also known as the luminosity bump. While the endpoint of this bump is well understood, its onset…
Astronomers discover two stars that joined together to form a binary system just 60 years ago
Using ALMA, astronomers have watched as two stars come together to form a massive stellar binary, finding chaos that indicates they emerged from different backgrounds.
Long-lost fish species rediscovered in another section of the Inn River
The Danube gudgeon had been considered extinct in the Inn River for more than 100 years. Only a few years ago, the highly endangered species was rediscovered there. Now, researche…
Helium measurements clarify conditions seconds after the Big Bang
New observations of the composition of distant galaxies offer insights into the earliest phases of the universe and confirm decades of scientific understanding of the elements and…
AI reveals new class of cellular 'off switch' linked to cancer pathways
Cornell researchers have used artificial intelligence to uncover a previously unknown way cells control how proteins move inside them, a process essential for growth, communicatio…
NASA’s Chandra Unveils Mysterious X-Ray Objects
Using NASA’s Chandra X-ray Observatory, scientists have discovered a new class of objects behaving unlike any they have seen before. Astronomers suggest these newly spotted object…
Fossils from embryo to adult suggest how an enigmatic, bird-like troodontid dinosaur grew
Analysis of fossilized remains from dinosaurs known as troodontids reveals how one species' hip and leg bones may have developed over its lifespan, from embryo to adult—with poten…
Asian elephants can resist impulsive behavior, researchers find
Researchers at the CUNY Graduate Center and Hunter College have found that Asian elephants can suppress impulsive behaviors and adjust their actions when circumstances change—a co…
JWST discovers that Chariklo's invisible rings are changing
Until just over a decade ago, ring systems were thought to be exclusive to the giant planets of the solar system, such as Jupiter, Saturn, Uranus and Neptune. However, in 2013, a …
NASA's newly launched Roman Space Telescope will 'directly' image exoplanets. But what does that mean?
