Scientists block Ebola infection in cell-culture experiments

Researchers at the University of Texas Medical Branch at Galveston have discovered two biochemical pathways that the Ebola virus relies on to infect cells. Using substances that block the activation of those pathways, they've prevented Ebola infection in cell culture experiments — potentially providing a critical early step in developing the first successful therapy for the deadly virus.

Video: Snakes improve search-and-rescue robots

Designing an all-terrain robot for search-and-rescue missions is an arduous task for scientists. The machine must be flexible enough to move over uneven surfaces, yet not so big that it's restricted from tight spaces. It might also be required to climb slopes of varying inclines. Existing robots can do many of these things, but the majority require large amounts of energy and are prone to overheat

More talk, less agreement: Risk discussion can hurt consensus-building on science/technology

When it comes to public issues pertaining to science and technology, "talking it out" doesn't seem to work. A new study from North Carolina State University shows that the more people discuss the risks and benefits associated with scientific endeavors, the more entrenched they become in their viewpoint – and the less likely they are to see the merit of other viewpoints.

Topical treatment wipes out herpes with RNAi

Whether condoms or abstinence, most efforts to prevent sexually transmitted diseases have a common logic: keep the pathogen out of your body altogether. While this approach is certainly reasonable enough, it doesn't help the countless people worldwide who, for a number of reasons, are not in a position to control their sexual circumstances.
