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 / 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 / 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 / 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 / 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 / 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 / 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 / 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 / HD⁺ ions cooled to 18 mK yield most precise vibrational-rotational spectra to date
A research team from the Innovation Academy for Precision Measurement Science and Technology (APM) of the Chinese Academy of Sciences has made significant progress in precisely measuring the vibrational-rotational spectra ...
Phys.org / Even moderate heat waves can depress sea urchin reproduction along the Pacific coast
Biologists thought that marine heat waves lowered urchin reproduction only at lethal temperatures. A new study shows reproductive shutdown even earlier.
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 ...
