Phys.org / AI math genius delivers 100% accurate results
At the 2024 International Mathematical Olympiad (IMO), one competitor did so well that it would have been awarded the Silver Prize, except for one thing: it was an AI system. This was the first time AI had achieved a medal-level ...
Phys.org / Ancient condors thrived on Peru's northern coast before retreating to the highlands, study reveals
In a recent study, Dr. Weronika Tomczyk and her colleagues conducted a zooarchaeological and isotopic study of ancient Andean condor bones from an archaeological site Castillo de Huarmey, providing the first and earliest ...
Phys.org / Rediscovery of lost fish species provides a second chance for conservation
Researchers have announced the rediscovery of Moema claudiae, a species of seasonal killifish in Bolivia that was previously thought to be possibly extinct. This rediscovery provides new hope for the conservation of this ...
Phys.org / Catalyst turns methane into bioactive compounds for the first time
Natural gas—one of the planet's most abundant energy sources—is primarily composed of methane, ethane, and propane. While it is widely burned for energy, producing greenhouse gas emissions, scientists and industries have ...
Phys.org / Electrical control of spin currents in graphene via ferroelectric switching achieved
A collaborative European research team led by physicists from Slovak Academy of Sciences has theorized a new approach to control spin currents in graphene by coupling it to a ferroelectric In2Se3 monolayer. Using first-principles ...
Phys.org / How cells preserve mitochondrial DNA quality across generations
Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations in mitochondrial DNA, the small but vital genome that powers every cell. The study, published in ...
Phys.org / World's oldest RNA extracted from woolly mammoth
Researchers from Stockholm University have—for the first time ever—managed to successfully isolate and sequence RNA molecules from Ice Age woolly mammoths. These RNA sequences are the oldest ever recovered and come from ...
Phys.org / Bacterial enzyme uses vitamin C to neutralize immune defenses, study finds
Throughout evolution, pathogenic microorganisms, such as bacteria, viruses, and fungi, have developed sophisticated defense strategies to survive and multiply in the hostile environment of their hosts. These mechanisms increase ...
Phys.org / Chang'e-6 samples reveal first evidence of impact-formed hematite and maghemite on the moon
A joint research team from the Institute of Geochemistry of the Chinese Academy of Sciences (IGCAS) and Shandong University has for the first time identified crystalline hematite (α-Fe2O3) and maghemite (γ-Fe2O3) formed ...
Phys.org / Shocked galaxy clusters: Unraveling the mysteries of radio relics
Galaxy clusters are the largest gravitationally bound structures in the universe, with each containing hundreds or even thousands of galaxies. When two of these giants collide, they send powerful shock waves through one another, ...
Phys.org / Fighting poverty may require cultural wisdom, not just cash
Most poverty-fighting efforts focus on meeting basic material needs, such as food and shelter. But this overlooks the psychological and cultural factors that shape how people take action in their lives.
Phys.org / Reading a quantum clock costs more energy than running it, study finds
A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping—the act of measurement itself. In a study published in Physical Review Letters, scientists demonstrate that the ...
