Phys.org / Hawai'i high school students name image of glittering galaxy pair
Nā ʻUhane Māhoe Huki Pū i ke Ola is the Hawaiian name given to NGC 7253—a pair of spiral galaxies caught in each other's gravity. Captured by the Gemini North telescope on Maunakea in Hawai'i, the image created a spectacular ...
Phys.org / 'Quiet' pulsar suddenly reveals three glitches in 15 years of observations
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery. ...
Phys.org / Extreme pressure turns blue pigment into record-long single-atom copper chains
As the electronics in our technology keep shrinking, traditional silicon-based chips are approaching their fundamental physical limits. Yet the wires connecting them might be able to shrink beyond conventional dimensions, ...
Medical Xpress / A single workout may help protect memory after a short night's sleep
Modern lifestyles, longer light exposure and constant digital distractions have pushed the world into a global sleep crisis—one that poses a major threat to public health. Sleep loss doesn't just leave us tired and irritable; ...
Medical Xpress / Experimental cancer drug could help millions of women battling osteoporosis and midlife weight gain
An experimental cancer drug could stop osteoporosis and help women stay slim after menopause, according to new research from the University of East Anglia. The study, published in npj Drug Discovery, reveals that a compound ...
Phys.org / Betelgeuse's atmosphere is becoming spotty and asymmetric—and a nearby companion could be shaping the pattern
For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led by Bill Dent at the University of Manchester, ...
Phys.org / FAST finds two mysterious hydrogen clouds with no visible stars
Astronomers have found two clouds of hydrogen near the Whirlpool galaxy that appear to contain almost no stars. The clouds, discovered with China's FAST radio telescope, each contain roughly 3 million times the mass of the ...
Tech Xplore / Iron could make high-energy sodium-ion batteries last longer
Lithium-ion batteries (LiBs), which charge and discharge by moving lithium ions between two electrodes known as the cathode and anode, remain the most widely used rechargeable batteries worldwide. Over the past decades, however, ...
Phys.org / The extinct American 'cheetah' was not a cheetah after all
With their slender bodies and long front legs, Miracinonyx trumani—often nicknamed the "American cheetah"—was long thought to be a North American analog of the African big cat. But in a new study published in the journal ...
Phys.org / Critically endangered pygmy raccoons observed making their own paper toys
Some of the most intriguing scientific breakthroughs happen when researchers aren't explicitly looking for them. Take, for example, the pygmy raccoon (Procyon pygmaeus), a critically endangered species that lives only on ...
Phys.org / How bird movements are helping researchers track a global virus
While the highly virulent avian influenza strain has only recently been discovered on Australian shores, researchers at Deakin University have been working behind the scenes for years, anticipating what an outbreak might ...
Phys.org / Particle shape and size predict asteroid strength, revealing Bennu's surface is 50 times weaker than ground coffee
In a new Nature Communications study, researchers developed a universal scaling framework for the strength of granular asteroids, showing that their tensile strength can be predicted from the size and shape of their constituent ...
