Looking for the anti-Alzheimer's molecule: New approach to treating a devastating disease

  • PDF
TechAndComputer (Nov. 7, 2012) — Researchers at Dalhousie University have discovered a new technique using "computer-aided" drug design that may lead to an entirely new approach in the treatment of Alzheimer's disease (AD).

"Alzheimer's is a devastating disease for which no truly disease-modifying drugs are available. Our approach is completely novel. We explore how the human body attempts to protect itself from Alzheimer's, and then we exploit this to develop an entirely new approach to therapeutics," explained Dr. Weaver, a professor at Dalhousie University, clinical neurologist at Capital Health and IWK Health Centre, Canada Research Chair in Clinical Neuroscience, and the DMRF Irene MacDonald Sobey Chair in Curative...

Crystals for efficient refrigeration: Can pump or extract heat, even on the nanoscale, for use on computer chips

The image shows a molecular dynamics simulation of lithium niobate under a time varying electric field, which changes the sign of the polarization. Red is niobium, green is oxygen, and lithium shows a range of colors for different time steps. The niobium and oxygen are shown only for one time step for clarity. The image shows a small part of the actual simulation. (Credit: Maimon Rose and Ronald Cohen Carnegie Institution)

How presidential candidates' actions speak louder than their words

  • PDF
TechAndComputer (Nov. 5, 2012) — New York University and the University of California, Berkeley have released a comprehensive computerized study of the body language of the major-party U.S. presidential candidates, using expertise of computer scientists and body language experts at both universities.

The team, whose work appears on its research site, GestureCloud.Org, matched the words with the gestures of President Barack Obama and Republican nominee Mitt Romney on a word-by-...

Nanoscale plasmonic antennas called nonamers placed on graphene have the potential to create electronic circuits by hitting them with light at particular frequencies, according to researchers at Rice University. The positively and negatively doped graphene can be prompted to form phantom circuits on demand. (Credit: Rice University)

TechAndComputer (Oct. 10, 2012) — Rice University researchers are doping graphene with light in a way that could lead to the more...
