These tiny soil microbes could rescue crops from salty farmland

Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils. Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots and makes plants more resilie

Why nanoscale droplets don't coalesce and microscale droplets do

Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon chains, which makes it hydrophobic and insoluble

Cultural values may decide when comforting others feels like real support

When someone you love is upset, your first instinct may be to comfort them. To reassure them. To make them feel better. But what if that instinct isn't universal?

Unexpected pathway turns water and CO₂ into climate‑neutral methane on nickel–zirconia

Natural gas still plays an important role in many industrial sectors, but it is a climate-damaging fossil fuel. TU Wien and the University of Innsbruck have now discovered an unexpected reaction pathway that makes it possible to synthesize natural gas, or methane (CH4), using CO2

How PFAS chain length influences environmental fate and water treatment

Per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," are among the most persistent contaminants found in water systems worldwide. Their strong carbon-fluorine bonds make them highly resistant to degradation, allowing them to remain in the environm

Mice actively seek better views to make visual decisions, virtual reality experiments show

Animals don't experience the world passively. A hawk tilts its head to track prey. A person leans forward to read a sign. Scientists call this "active sensing": moving the body to gather better information. A specific version of active sensing is infotaxis, which describes how an

Black locust deploys peptides to steer root bacteria into nitrogen fixation

Plants need nitrogen to grow. Many legumes meet this need through a symbiotic relationship: They harbor bacteria that fix atmospheric nitrogen and make it available to the plant. Until now, it was largely unclear how a perennial plant regulates this symbiosis without destroying i
