Why carbon nanotubes spell trouble for cells

It's been long known that asbestos spells trouble for human cells. Scientists have seen cells stabbed with spiky, long asbestos fibers, and the image is gory: Part of the fiber is protruding from the cell, like a quivering ...

How hot is Schrodinger's coffee?

A new uncertainty relation, linking the precision with which temperature can be measured and quantum mechanics, has been discovered at the University of Exeter.

Scientists discover world's smallest superconductor

Scientists have discovered the world's smallest superconductor, a sheet of four pairs of molecules less than one nanometer wide. The Ohio University-led study, published Sunday as an advance online publication in the journal ...

The next medical frontier: nano-surgery

(PhysOrg.com) -- Engineering professor's nanorobot could be performing non-invasive surgical procedures on patients with tumors within the next decade.

Faster, cheaper DNA sequencing method developed

(PhysOrg.com) -- Boston University biomedical engineers have devised a method for making future genome sequencing faster and cheaper by dramatically reducing the amount of DNA required, thus eliminating the expensive, time-consuming ...

Nanoscale logic machines go beyond binary computing

(Phys.org)—Scientists have built tiny logic machines out of single atoms that operate completely differently than conventional logic devices do. Instead of relying on the binary switching paradigm like that used by transistors ...
