New York, NY : A new study published in the September 11, 2009 issue of Science by researchers at the NYU School of Medicine reveals a conceptually novel mechanism that plays an important role in making human pathogens like Staphylococcus aureus and Bacillus anthracis resistant to numerous antibiotics.

A review article in the journal Science this week summarizes the state of research on climate change in the Arctic. Among the findings — Arctic ecosystems have been severely disturbed. Lead author Eric Post, a biology professor at Penn State, discusses the report.

It’s Friday, our kids have been back at school a week now, so with the ever-present prospect of a wet weekend ahead of us, how to distract them from Youtube and Facebook with some educational that might help them next week in school… …so, how about a quick trawl for fun science games. It seems there [...]Fun Science Games is a post from: Sciencebase Science Blog

[NEWS] Unlike animals and humans, plants can't run and hide when exposed to stressful environmental conditions. So how do plants survive? A new Université de Montréal study, published in the journal Proceedings of the National Academy of Sciences, has found a key mechanism that enables plants to keep dangerous gene alterations in check to ensure their continued existence. “We've discovered a new pathway that plants use to protect their genes against dangerous alterations that c…

This week in Science, a multinational research project reported on the archaeological discovery of dyed and spun flax fibers from an Upper Paleolithic cave in the Republic of Georgia, dated to ~31,000-36,000 cal BP. Wild flax fibers from Unit C, Dzudzuana Cave, Georgia. Image courtesy of Science/AAAS Dzudzuana Cave is a rockshelter in Georgia, with four Upper Paleolithic occupations, the oldest dated between 31,000 and 36,000 calibrated years before the present. The flax fibers were discovered in clay samples taken from each of the four occupations, and found to have been cut, twisted, spun and woven, and, most surprisingly, dyed, in turquoise, pink, grey and black colors. I, naturally, had to make a photo essay out of this fascinating story.

In the wake of the Sigg/bisphenol-A controversy, a top researcher and CEO of Environmental Health Sciences fills us in on the news: endocrine disruptors such as BPA and phthalates are indeed toxic at low-level doses, too. And they’re toxic in entirely different ways than at the traditional high-dose testing indicates. The way the tests work today is we think that by testing at high doses we’re gonna see everything. So that once we get to a dose that’s intermediate and we don’t see anything, we’re golden. But the science is telling us that at really low doses as contaminants mimic hormones. They can have effects that are totally unpredictable by what happens at high doses. Pete Myers spoke to Living on Earth about the consequences of current testing. of this story »

On September 12, 1959, the Soviets launched the second of their Luna series spacecraft towards the moon. It was designed to confirm Luna 1's discovery of the solar wind and to impact on the surface of the Moon. It would impact the surface on September 14 to become the first man made object to reach the Moon. September 12, 1962 was the day President Kennedy made his Moon speech dedicating the nation's support to landing a man on the moon and bringing him back safely by the end of the decade. The United States would successfully meet this challenge on July 20, 1969. Find out what else occurred on this day in science history.

One of the most intriguing developments in recent medical science is the discovery of the human chemical endothelin (ET). Since its detection in 1988, over 22,000 scholarly articles (about 3 per day) have been published on the subject, a new class of drugs has been developed, and 25 Phase I, II and III clinical trails are now underway.
