Phys.org / Mapping the 'hidden highways' of Mexico's illegal wildlife trade
For decades, wildlife traffickers have illegally captured and sold hundreds of thousands of wild parrots native to Mexico. Despite changes to international wildlife laws, the conservation status of these birds has continued ...
Phys.org / Corners in focus: Metasurface enables motion tracking without digital image processing
A research team at City University of Hong Kong (CityUHK) has developed a new optical corner-detection imaging method that uses azimuthal Hilbert transform metasurfaces and is designed to work as a universal framework. The ...
Phys.org / New free-space optical link adds a wireless component to the nation's longest quantum network
There's a new lighthouse on Long Island. But instead of shining light to guide ships through waterways, this one transmits and receives particles of light that carry quantum information. Perched atop a seven-story building ...
Phys.org / What happens inside a wildfire? A Ph.D. student is finding out
What happens during a wildfire? The short answer is: much more than we know. As wildfires burn through trees, grasses and other vegetation, heat from the flames sets off thousands of chemical reactions at once. Molecules ...
Phys.org / A 2-degree twist creates a nanoscale grid that traps light energy at room temperature
You may have once tried taking a close-up picture of a computer screen and noticed a wavy, rippling effect. This optical effect occurs whenever two fine, repeating grids overlap and slightly misalign, such as when the pixel ...
Phys.org / Ball milling enhances the antiviral activity of inexpensive inorganic materials
Since the COVID-19 pandemic, developing surfaces that can inactivate viruses upon contact has become an important goal in public health care. Ideally, such surfaces would work on their own without requiring chemical disinfectants, ...
Phys.org / LST-1 and MAGIC telescopes shatter distance record for the very high-energy blazar OP 313
On Aug. 15, the CTAO LST Collaboration and the MAGIC Collaboration released findings from observations of OP 313, the most distant very-high-energy blazar ever recorded. The paper, published in Astronomy & Astrophysics, presents ...
Phys.org / Soil bacteria share amino acids, helping nearly half survive nutrient gaps
Bacteria, too, depend on good neighborly relations: A new study by the Osnabrück University, in collaboration with researchers from the University of Cambridge in England, shows that soil bacteria live in beneficial communities ...
Phys.org / Antarctic bacteria share 'life‑support' genes to survive extreme conditions
Antarctica is one of the driest, coldest places on Earth. Very little life survives its extremes. In the soils scattered around the frozen ice sheets, however, communities of microbes do survive. And one of the keys to their ...
Phys.org / Mechanical memory helps explain how cells adapt their movement to changing environments
Cells in our bodies squeeze through dense tissue channels, thread past neighboring cells and navigate every nook and cranny within the extracellular matrix—the mesh-like network that surrounds and supports cells. How well ...
Phys.org / Tiny root hairs, big impact: How bacteria help plants survive drought
What helps plants cope better with drought? With heat waves and periods of extreme drought becoming increasingly common worldwide, the need for drought-tolerant plants is increasingly urgent. With the help of bacteria, plants ...
Phys.org / Climate scientists solve monsoon puzzle and warn of risks to fisheries
A new study has reconciled a long-standing paradox in the South Asian summer monsoon cycle. Climate scientists have discovered why geological records from land and sea have told opposite stories about monsoons throughout ...
