Phys.org / Two's company: Scientists identify new class of star remnants
In about 5 to 8 billion years, our sun is expected to evolve into a white dwarf—an extremely dense, Earth-sized stellar remnant that has exhausted its fuel and shed its outer layer. But while our sun is a solitary star, research ...
Phys.org / Artemis astronauts more than halfway to Moon, putting Earth in rearview
The Artemis 2 astronauts have passed the halfway point between Earth and the moon on Saturday as they sped toward a planned lunar flyby, with NASA releasing initial images of Earth taken from inside the Orion spacecraft.
Phys.org / Artemis II's moonbound astronauts capture Earth's brilliant blue beauty as they leave it behind
The Artemis II astronauts have captured our blue planet's brilliant beauty as they zoom ever closer to the moon.
Phys.org / A simple ECG test could flag racehorses at risk of exercise arrhythmias
A quick heart trace taken during a warm-up trot could identify racehorses at risk of cardiac arrhythmias during high-intensity exercise, according to a new study led by the University of Surrey. The screening method analyzes ...
Phys.org / The most pristine star yet found in the known universe
An unusual team of astronomers used Sloan Digital Sky Survey-V (SDSS-V) data and observations on the Magellan telescopes at Carnegie Science's Las Campanas Observatory in Chile to discover the most pristine star in the known ...
Phys.org / Tiny African fish caught climbing to the top of a 50-foot waterfall
For over half a century, people in Central Africa have told tales of the fish seen climbing waterfalls, but these claims have never been officially confirmed. Now, these fish have finally been caught on camera, studied more ...
Phys.org / A tiny detector for microwave photons could advance quantum tech
Detecting a single particle of light is hard; detecting a single microwave photon is even harder. Microwave photons, the tiny packets of electromagnetic radiation used in current technologies like Wi-Fi and radar, carry far ...
Phys.org / The depths of Neptune and Uranus may be 'superionic'
The interiors of ice giant planets like Uranus and Neptune could be home to a previously unknown state of matter, according to new computational simulations by Carnegie's Cong Liu and Ronald Cohen. Their work, published in ...
Phys.org / Scientists discover a 1,200-year-old Fijian island likely built from discarded shellfish remains
Located off the coast of Culasawani, in the Fiji archipelago, is an island that is made up of materials that might be part of someone's dinner. A recent study took a closer look at the 3,000-square-meter island and discovered ...
Phys.org / Quantum coherence could be preserved at large scales in realistic environments
Quantum states are notoriously fragile, and can be destroyed simply through interactions, measurements, and exposure to their surrounding environments. In a new theoretical study published in Physical Review X, Rohan Mittal ...
Phys.org / Bacterial enzyme uses a donut-shaped ring to shred tough collagen, study reveals
Collagen is an important protein that helps build the tissues of humans and animals. It is very strong because it is made of three protein strands twisted tightly together like a rope. Because of this sturdy structure, ordinary ...
Phys.org / Small quantum system outperforms large classical networks in real-world forecasting
Can a handful of atoms outperform a much larger digital neural network on a real-world task? The answer may be yes. In a study published in Physical Review Letters, a team led by Prof. Peng Xinhua and Assoc. Prof. Li Zhaokai ...
