New Gold Nanoparticle-Based Method for Target Identification of Bioactive Small Molecules

The development of pharmaceutical treatments is difficult -- clinicians and researchers know a certain drug can regulate particular functions, but they might not know how it actually works. Researchers at Tokyo University of Agriculture and Technology (TUAT) have developed a new, streamlined method to better understand the molecular mechanisms underpinning these interactions.

Researchers Create Artificial Muscles by Twisting and Coiling Carbon Nanotubes

For more than 15 years, researchers at The University of Texas at Dallas and their collaborators in the U.S., Australia, South Korea and China have fabricated artificial muscles by twisting and coiling carbon nanotube or polymer yarns. When thermally powered, these muscles actuate by contracting their length when heated and returning to their initial length when cooled. Such thermally driven artificial muscles, however, have limitations.
