Phys.org / Public seed banks can fast-track corn quality research
University of Illinois Urbana-Champaign corn breeders know profitability is about more than yield. By tweaking kernel composition, they can tailor corn for lucrative biotech applications, industrial products, overseas markets, ...
Phys.org / Decaying dark matter: Unidentified X-ray emission lines in galaxy cluster spectra may point the way
Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines or neutrino signals not seen in normal matter, potentially revealing dark matter's particle nature, ...
Phys.org / 13 years of detailed US CO₂ emissions data released
New research from Northern Arizona University shows detailed CO2 emissions for the United States from 2010 to 2022.
Phys.org / Ancient hunter-gatherer DNA may explain why some people live to 100 years or more
Our hunter-gatherer ancestors have given us many things. They passed down mastery of fire for cooking and early survival technologies, such as stone tools. They may also have given us the secret to a long life. A new study ...
Phys.org / Physicists push superconducting diodes to high temperatures
For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a supercurrent to flow in both directions. Published in Nature Physics, the team's result could help ...
Phys.org / Saturn's rings extend further above and below the ring plane, forming a 'halo'
The Cassini probe took its final orbits, referred to as the Grand Finale Orbits (GFOs), in 2017, before launching itself into Saturn's atmosphere. During these GFOs, the probe collected samples of dust above and below Saturn's ...
Phys.org / Subtle twist in materials prompts surprising electromagnetic behavior
Materials react differently to electric and magnetic fields, and these reactions are known as electromagnetic responses. In many solid materials, unusual electromagnetic responses have been known to only emerge when specific ...
Phys.org / How a new diet of penguins is changing puma behavior and social lives in Patagonia
Penguins in the coastal steppes of Argentina have a new enemy to worry about: the increasing numbers of pumas in Monte León National Park (MLNP). These powerful mountain cats were once on the brink of disappearing from this ...
Phys.org / Active thermal metasurfaces amplify heat signatures by a factor of nine
Light undergoes a unique phenomenon called superscattering, an optical illusion where a very small object scatters far more light than expected. This happens when multiple scattering modes overlap and interact, allowing tiny ...
Phys.org / Sourdough starters: How flour choice shapes microbial communities
Sourdough starter, a fermented mix of flour and water, is a staple for bakers. It's also a rich experimental testing ground for microbiologists. The bread's chewy texture and tangy taste arise from the mix of microbes that ...
Phys.org / Conventional entanglement can have thousands of hidden topologies in high dimensions
Researchers from the University of the Witwatersrand in South Africa, in collaboration with Huzhou University, discovered that the entanglement workhorse of most quantum optics laboratories can have hidden topologies, reporting ...
Phys.org / The perfect polymer? Plant-based plastic is fully saltwater degradable and leaves behind zero microplastics
Researchers led by Takuzo Aida at the RIKEN Center for Emergent Matter Science (CEMS) in Japan have one-upped themselves in their quest to solve our microplastic problem.
