Electrochemical method supports nitrogen circular economy

Imagine a world where industrial waste isn't just reduced, it's turned into something useful. This kind of circular economy is already in the works for carbon. Now, researchers at Washington University in St. Louis have developed ...

Transistor reshapes electronic properties of a 2D material

A RIKEN study shows that squeezing the right amount of potassium ions between the atomic layers of molybdenum disulfide can turn it from a semiconductor into a metal, superconductor or insulator. The same layered material ...

DNA microscope creates 3D images of organisms from the inside out

Standard genetic sequencing approaches can tell you a lot about the genetic makeup and activity in a sample, like a piece of tissue or drop of blood. But they don't tell you where specific genetic sequences were located inside ...

Drone experiment reveals how Greenland ice sheet is changing

For the first time, researchers have collected detailed measurements of water vapor high above the surface of the Greenland ice sheet. Their research, aided by a custom-designed drone, could help scientists improve ice loss ...

Cyanide plays a major role in the human body, study reveals

Cyanide is a highly lethal chemical that has been used in warfare and poisonings for centuries—that was the general consensus on the naturally occurring chemical up until spring 2025. But in a global study published in ...
