Scientists unveil hidden step in enzyme mechanism

An international research team led by the University of Leicester has made a breakthrough advance by trapping an intermediate in the mechanism of enzymes called heme peroxidases and determining its structure using a beam ...

Record distance for alternative super-current

Researchers have discovered that electrons that spin synchronously around their axes remain superconductive across large distances within magnetic chrome dioxide. Electric current from these electrons can flip small magnets, ...

Melting Greenland ice threatens to expose Cold War waste

A snow-covered former US army base in Greenland—dubbed "a city under ice"—could leak pollutants into the environment as the climate changes, raising difficult questions over who is responsible for a clean-up.

Hundred million degree fluid key to fusion

Scientists developing fusion energy experiments have solved a puzzle of why their million-degree heating beams sometimes fail, and instead destabilise the fusion experiments before energy is generated.
