TechAndComputer (Dec. 4, 2012) — Using computational techniques, researchers in Spain have shown how a protein responsible for the maturation of the virus releases itself to initiate infection.

Bioinformaticians at IMIM (Hospital del Mar Medical Research Institute) and UPF (Pompeu Fabra University) have used molecular simulation techniques to explain a specific step in the maturation of the HIV virions, i.e., how newly formed inert virus particles become infectious, which is essential in understanding how the virus replicates. These results, which have been published in the latest edition of PNAS, could be crucial to the design of future...

Sharp spike in computer-related injuries predicted for medical workers, find studies

  • PDF
TechAndComputer (Dec. 3, 2012) — As U.S. health care goes high tech, spurred by $20 billion in federal stimulus incentives, the widespread adoption of electronic medical records and related digital technologies is predicted to reduce errors and lower costs -- but it is also likely to significantly boost musculoskeletal injuries among doctors and nurses, concludes a Cornell University ergonomics professor in two new papers.

The repetitive strain injuries, he said, will stem from...

Mimicking public health strategies could improve cyber security

  • PDF
TechAndComputer (Nov. 29, 2012) — Mimicking public health strategies, such as maintaining good "cyber hygiene," could improve cyber security, according to a new paper by a team of economists and public health researchers at RTI International.

The paper, published in the November/December issue of Cross Talk, provides a substantive look at how public health strategies and research methodologies could be used to guide cyber security strategies.

Currently, no centralized...

Leap forward in brain-controlled computer cursors: New algorithm greatly improves speed and accuracy

  • PDF
These diagrams trace the accuracy of various trial scenarios of the ReFIT algorithm developed at Stanford. On the left is a a real arm. In the middle, the monkey uses ReFIT and on the right the monkey uses the old algorithm. Note the tendency of the old algorithm to overshoot the target and, conversely, how the ReFIT traces closely resemble those of the real arm. (Credit: Vikash Gilja, Stanford University)
