Stealth technology maintains fitness after sex

Pathogens can become superbugs without their even knowing it, research published today in Science shows. 'Stealth' plasmids -- circular 'DNA parasites' of bacteria that can carry antibiotic-resistance genes -- produce a protein that increases the chances of spread of the antibiotic-resistant strain. The team, from Trinity College Dublin, Ireland, and the Wellcome Trust Sanger Institute, Cambridge, UK, suggest that low-cost plasmids, described for the first time in the study, are a threat to use of antibiotics.

1. Sulfur dioxide may have helped maintain a warm early Mars
   12-20-2007 · EurekAlert!
   Sulfur dioxide (SO2) may have played a key role in the climate and geochemistry of early Mars, geoscientists at Harvard University and the Massachusetts Institute of Technology suggest in the Dec. 21 issue of the journal Science. Their hypothesis may resolve longstanding questions about evidence that the climate of the Red Planet was once much warmer than it is today.

2. Ames Laboratory beefing up magnets for electric-drive cars
   01-09-2008 · EurekAlert!
   One of the roadblocks for electric motor technology is that as operating temperatures go up, the magnets in the motors get weaker, resulting in a drop in power. Ames Laboratory Researcher Iver Anderson and his team have developed a new magnetic alloy that maintains its strong magnetic properties even at high operating temperatures approaching 400 degrees F.

4. New buffer resists pH change, even as temperature drops
   01-14-2008 · EurekAlert!
   Researchers at the University of Illinois have found a simple solution to a problem that has plagued scientists for decades: the tendency of chemical buffers used to maintain the pH of laboratory samples to lose their efficacy as the samples are cooled. The research team, headed by chemistry professor Yi Lu, developed a method to formulate a buffer that maintains a desired pH at a range of low temperatures.

7. Study finds strong demand for HIV meds after high-risk sex
   11-08-2007 · EurekAlert!
   People who do not have HIV but seek antiretroviral medications following high-risk sexual encounters are very likely to complete the full month-long drug regimen, according to a new UCLA AIDS Institute study. Moreover, there is a strong demand for publicly available post-exposure prophylaxis among high-risk populations in Los Angeles County. Based on these findings, the researchers recommend that Los Angeles County make post-exposure HIV prophylaxis available to citizens who have engaged in high-risk sex.

8. Violent sex acts boost insect's immunity system
   12-04-2007 · EurekAlert!
   The long-held idea that only vertebrates have sophisticated adaptive immune systems that can protect them for life against many pathogens after being infected by them just once has been revised in recent years. It turns out that many insects also have a form of immune memory that protects them against reinvasion by a pathogen they have previously encountered.
