Researchers at Stanford University have observed the detailed structure of red sprites, finding thousands of vertical and tilted streamers with branching patterns. The findings suggest that electrostatic charge buildup in the atmosphere creates these spark channels, which ionize air molecules and produce glowing red streamers.
Some smelter slags produce toxic elements like arsenic, lead, cadmium, and copper when exposed to natural weathering conditions. Researchers have found high levels of these elements in slag dumps, contaminating nearby water sources.
Researchers coax bacteria from contaminated soil into cleaning up toxic heavy metal chromium by adding appropriate nutrients. The team aims to optimize microbial action at contaminated sites for effective bioremediation.
Scientists have developed SAMMS, a self-assembled monolayer on mesoporous support that selectively binds toxic or precious metals like mercury and lead. The technology has shown promise in cleaning up contaminated waterways and recovering valuable metals.
A Florida biologist found that subtle increases in CO2 can kill mining moths by reducing the nutritional value of their food. Many more larvae died in chambers with high CO2 levels, likely due to malnutrition caused by lower nitrogen content.
Researchers at Boston University and Japan's University of Tokyo found evidence that neutrinos possess mass, contradicting the standard theory of particle physics. This discovery may impact our understanding of the universe's expansion and potential unification of particles and forces.
