Phys.org / Building blocks of life discovered in Bennu asteroid rewrite origin story
Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an asteroid called Bennu, delivered to Earth in 2023 by NASA's OSIRIS-REx mission. How those amino acids—the ...
Phys.org / Extreme plasma acceleration in monster shocks offers new explanation for fast radio bursts
In a new study published in Physical Review Letters, scientists have performed the first global simulations of monster shocks—some of the strongest shocks in the universe—revealing how these extreme events in magnetar ...
Phys.org / 7,000-year-old deer antler headdress from Eilsleben illustrates contact between hunter–gatherers and early farmers
Central Germany is among the regions where, as early as the mid-6th millennium BC, farmers displaced the Mesolithic hunter–gatherers from the fertile loess soils. Soon after this migration, however, exchange began between ...
Phys.org / A familiar magnet gets stranger: Why cobalt's topological states could matter for spintronics
The element cobalt is considered a typical ferromagnet with no further secrets. However, an international team led by HZB researcher Dr. Jaime Sánchez-Barriga has now uncovered complex topological features in its electronic ...
Medical Xpress / Common anti-seizure drug prevents Alzheimer's plaques from forming, study shows
While physicians and scientists have long known that Alzheimer's disease involves the buildup of toxic protein fragments in the brain, they have struggled to understand how these harmful fragments are produced. Now, in a ...
Phys.org / How redox reactions drive bacteria's Na⁺-NQR sodium pump
The enzyme Na⁺-NQR is a sodium pump that drives the respiration of many marine and pathogenic bacteria. Using redox reactions, the process of exchanging electrons between materials, it powers the transportation of sodium ...
Phys.org / 'It ain't no unicorn': Meet the researchers who've interviewed 130 Bigfoot hunters
It was the image that launched a cultural icon. In 1967, in the northern Californian woods, a seven foot tall, ape-like creature covered in black fur and walking upright was captured on camera, at one point turning around ...
Phys.org / How often do people feel passionate love? Study finds about two lifetime loves
Falling passionately in love is one of the most talked about human experiences, celebrated in songs, movies, literature, and art across cultures. Passionate love is widely considered a hallmark of romantic relationships and ...
Phys.org / Carbon nanotube 'sandpaper' polishes semiconductor surfaces down to a few atoms
The performance and stability of smartphones and artificial intelligence (AI) services depend on how uniformly and precisely semiconductor surfaces are processed. KAIST researchers have expanded the concept of everyday "sandpaper" ...
Phys.org / Topological antenna could pave the way for 6G networks
Using ideas borrowed from topological photonics, researchers in Singapore, France and the US have designed a compact antenna capable of handling information-rich terahertz (THz) signals. Reporting their results in Nature ...
Phys.org / The hidden impact of polluted snow
As Canada experiences record snowfall, new research from the University of Waterloo suggests that tiny amounts of industrial pollution trapped in snow can change how sunlight reaches the ground below and significantly alter ...
Medical Xpress / Deadly Nipah virus deemed 'limited' by scientists
Named for the Malaysian village where it was first identified, the Nipah virus is an infectious disease transmitted primarily by bats.
