Phys.org / DNA caught on old air filters reveals hidden past of ecosystems
DNA captured on air filters and stored since the 1960s acts as an ecological time capsule, according to a recent publication in Nature Communications. The findings show that tiny fragments of genetic material can paint a ...
Phys.org / Enzyme shape-shifting captured in real time during catalysis
Researchers have captured real-time "molecular movies" showing how an enzyme changes shape during catalysis. The study was published in Nature Communications.
Phys.org / Cell death discovery could aid cancer treatments
La Trobe researchers have made a discovery about the way dying cells are cleared from our bodies, which could have important impacts on recovery from diseases including cancer infection and inflammatory diseases.
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 / 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 / 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 / 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 ...
