Trending science: Vitamin B3 may have been delivered from space

The results of laboratory experiments involving Vitamin B3 by a team of NASA researchers support a theory that the origin of life may have been assisted by a supply of 'biologically important molecules produced in space and ...

Smallest possible diamonds form ultra-thin nanothreads

For the first time, scientists have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. ...

Radiation damage spreads among close neighbors

A single X-ray can unravel an enormous molecule, physicists report in the March 17 issue of Physical Review Letters. Their findings could lead to safer medical imaging and a more nuanced understanding of the electronics of ...

Hydrogen opens the road to graphene ... and graphane

(PhysOrg.com) -- An international research team has discovered a new method to produce belts of graphene called nanoribbons. By using hydrogen, they have managed to unzip single-walled carbon nanotubes. The method also opens ...

Twisted crystals point way toward active optical materials

(PhysOrg.com) -- A nanoscale game of "now you see it, now you don't" may contribute to the creation of metamaterials with useful optical properties that can be actively controlled, according to scientists at Rice University.
