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 / 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 / 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 / Offsetting blue carbon benefits: Mangrove tree stems identified as previously underestimated methane source
Mangrove ecosystems rank among the most efficient "blue carbon" systems on Earth, capable of absorbing and storing vast quantities of atmospheric carbon dioxide (CO2). However, mangroves also release methane (CH4), a potent ...
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 / Twin Mars orbiters launched on New Glenn rocket to study Martian atmosphere
Blue Origin launched its huge New Glenn rocket Thursday with a pair of NASA spacecraft destined for Mars.
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 / 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 ...
Phys.org / The 'Great Unified Microscope' can see both micro and nanoscale structures
Researchers at the University of Tokyo have built a microscope that can detect a signal over an intensity range 14 times wider than conventional microscopes. Moreover, the observations are made label-free, that is, without ...
