Finding superconducting needles in the metal haystack

The discoverer of the first iron-based superconductor, one of Science magazine's 2008 runner-up breakthroughs of the year, now reports finding around 100 new superconducting materials.

Manipulating cell membranes using nanotubes

Japanese researchers have developed a targeted method for opening up cell membranes in order to deliver drugs to, or manipulate the genes of, individual cells.

Protein mimic shows promise as tissue engineering glue

Researchers have demonstrated the potential of a "synthetic protein mimic" to promote the adhesion of brain cells in a laboratory setting. This feat could help overcome a major challenge in nerve tissue engineering.
