Researchers have discovered precisely how the antibiotic linezolid inhibits bacterial growth.

Cognitive therapy is an effective treatment for post-traumatic stress disorder related to acts of terrorism and other civil conflict, finds a new study.

Pigs carry hepatitis E virus (HEV), which they can pass on to humans. Scientists analysed blood test data from 2,500 pigs, natural hosts for the virus, on Japanese farms. They found that by the age of 150 days, over 95% of pigs had been infected with HEV.

A Swedish research team has used theoretical calculations to show that hydrogen is soluble in iron under the special conditions that prevail in the core of the earth. The findings explain some discrepancies between experiments and theory.

Using an innovative statistical approach, a research team has identified two regions of DNA linked to autism. They found the suspicious DNA with a much smaller sample of people than has been used traditionally in searches for autism genes.

Security holes in media player and compression software had not previously been used in cyberattacks, according to Symantec.

Two bills win unanimous approval from a key committee, paving the way for a floor vote, but some outside Congress still have reservations.

Earlier this week we noted that the latest GAO report found that industry estimates of the impact of counterfeiting and piracy on the economy were greatly exaggerated, and now the Organization for Economic Co-operation and Development (OECD) has come out with a similar report, noting not just that the numbers are exaggerated, but that the exaggeration was done by lobbyists to further political policies. No, really? The report does still say that counterfeiting and piracy is a problem -- but just that it's not nearly as big a problem as industry representatives would have you believe, and that industry reps might be better off not focusing so heavily on passing stronger intellectual property laws around the world. Not surprisingly, the very same lobbyists were quick to trash the OECD report, and even (you knew this was coming) claim that their estimates on piracy and counterfeiting were conservative. So here we have two non-industry groups with no reason for bias reporting that the "loss" numbers industry representatives claim are clearly bogus. Does this mean that the media will stop reporting the industry's totally unsupported numbers as if they were factual?

The identification of a cluster of essential genes on mouse chromosome 11 as well as similar clusters on the chromosomes of other organisms -- including humans -- buttresses the argument that there may be rules as to how genes are structured or laid out on chromosomes, according to recent research.

Research at Northwestern University has shown that a combination of nanotechnology and biology may enable damaged tissues and organs to heal themselves. In a dramatic demonstration of what nanotechnology might achieve in regenerative medicine, paralyzed lab mice with spinal cord injuries have regained the ability to use their hind legs six weeks after a simple injection of a purpose-designed nanomaterial.
