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 / 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 / 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 / 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 / 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 ...
