Crumpled graphene makes ultra-sensitive cancer DNA detector

Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient's blood or serum. But current designs need a lot of DNA. In a new study, crumpling graphene makes it ...

First artificial enzyme created with two non-biological groups

Scientists at the University of Groningen turned a non-enzymatic protein into a new, artificial enzyme by adding two abiological catalytic components: an unnatural amino acid and a catalytic copper complex. This is the first ...

Six degrees of nuclear separation

Argonne scientists look to 3-D printing to ease separation anxiety, which paves the way to recycle more nuclear material.

Researchers show how railroad worms produce red light

A research group comprising Brazilian and Japanese scientists has discovered how luciferase produced by the railroad worm Phrixothrix hirtus emits red light. Luciferase is an enzyme that catalyzes the oxidation of luciferin ...
