Both literally and figuratively, light pervades the world. It banishes darkness, conveys telecommunications signals between continents and makes visible the invisible, from faraway galaxies to the smallest bacterium. Light ...
Nonlinear light microscopy has revolutionized our ability to observe and understand complex biological processes. However, light can also damage living matter. Yet, the mechanism behind the irreversible perturbation of cellular ...
Researchers at the Center for Research on Redox Processes in Biomedicine (Redoxome) in Brazil have identified extracellular matrix proteins modified by the action of hypobromous acid in normal and fibrotic lung tissues, suggesting ...
The sun's surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed that the sun's field is ...
For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, akin to the focusing of sound waves responsible for the Rotunda effect in architecture or the focusing of light by a ...
The seabed contains large quantities of valuable minerals and metals that are urgently needed for modern technologies such as electric cars and wind turbines. However, discovering these deposits has so far been complicated. ...
Cigarette smoke has been studied for years, revealing a multitude of contaminants, including toxic metals. But exactly which of those metals can be traced to secondhand or thirdhand smoke?
Deposits of designated critical minerals needed to transition the world's energy systems away from fossil fuels may, ironically enough, be co-located with coal deposits that have been mined to produce the fossil fuel most ...
Tourists normally have to pay big money and brave cold climates for a chance to see an aurora, but last weekend many people around the world simply had to look up to see these colorful displays dance across the sky.
Research conducted in Brazil at the Center for Development of Functional Materials (CDMF) and the Center for Innovation in New Energies (CINE) has developed a novel approach to the plasma treatment of antimony tri-selenide ...
