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.

How a declining environment affects populations

Stable ecosystems occasionally experience events that cause widespread death—for example, bacteria in the human gut may be wiped out by antibiotics, or ocean life may be depleted by overfishing. A new study from MIT physicists ...

Petry finds missing ingredient to spark the fireworks of life

Most people can name at least a few bones of the human body, but not many know about the cytoskeleton within our cells, let alone the "microtubules" that give it its shape. Now, a group of Princeton researchers has resolved ...
