Phys.org / Mars rover detects never-before-seen organic compounds in new experiment
NASA's Curiosity Mars rover has uncovered a diverse mix of organic molecules on Mars, including chemicals widely considered building blocks for the origin of life on Earth.
Phys.org / Alternating atomic layers enable rare electron pairing mechanism in new unconventional superconductor
Superconductors, materials that can conduct electricity with a resistance of zero, have proved to be highly promising for the development of quantum technologies, medical imaging devices, particle accelerators and other advanced ...
Phys.org / CHIME tracks a hyperactive repeating fast radio burst source
Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME), an international team of astronomers has performed radio observations of FRB 20220912A—a highly active source of repeating fast radio bursts. Results of the ...
Phys.org / Put a nanodiamond under intense pressure and it becomes flexible
Diamond is among the hardest naturally occurring substances on Earth, but if you shrink it down to the nanoscale, it is surprisingly elastic. And that could be useful for a host of applications such as quantum computing. ...
Phys.org / Laser bursts flip nanoscale magnetic vortices at blistering speeds, opening a path to brain-like spintronics
Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to switch magnetic states is central to the functioning of these devices, as it ultimately allows ...
Phys.org / Pressure-tuned quantum spin liquid-like behavior observed in material Y-kapellasite
A quantum spin liquid is a phase of matter in which the magnetic moments in a material do not align or freeze, even at temperatures close to absolute zero (i.e., at 0 K). The experimental realization of this highly dynamic ...
Phys.org / Breakthrough sulfur polymer kills dangerous fungi and bacteria while sparing human and plant cells
Antimicrobial resistance is becoming a global burden in human health and food production, so affordable new materials are needed to overcome this growing problem. To answer the call, a multidisciplinary research team led ...
Phys.org / Black bears are emerging as roaming reservoirs of antibiotic-resistant bacteria across expanding US ranges
A new gut microbiome study of bears in eastern North Carolina expands our understanding of microbial ecosystems in omnivores and contributes to the broader idea that bear feces could help scientists monitor changes in the ...
Phys.org / Missing link in evolution of ancient fish found in 150-year-old museum specimen
A new species of coelacanth has been identified from a 150-year-old fossil housed at London's Natural History Museum. Former University of Portsmouth paleontology student Jack L. Norton located the coelacanth, which provides ...
Phys.org / Simple ocean-based model forecasts a powerful El Niño, over 2 °C warmer than normal
For decades, scientists have worked to improve predictions of El Niño-Southern Oscillation (ENSO), a climate powerhouse that can cause droughts, flooding, marine heat waves, and more around the world. Researchers from the ...
Phys.org / What Bronze Age people ate and drank: South Caucasus pottery reveals a surprisingly diverse menu
What culinary practices prevailed in the South Caucasus during the Bronze Age? A new study shows that the cuisine was remarkably diverse. The evidence highlights a multi-ingredient cuisine alongside the central role of dairy ...
Phys.org / Plastics found in tomato and wheat crops stunt growth, study finds
A study investigating microplastics (MPs) and nanoplastics (NPs) in agricultural settings has found they reduced plant growth and entered plant tissues through the soil, raising new concerns about food safety and human exposure. ...
