The two atoms of an oxygen molecule severed by a metal catalyst usually behave identically, but new research reveals that on a particular catalyst, one oxygen atom plants itself while the other moves away, probably with energy partially stolen from the stationary one.

Scientists from the Pacific Northwest National Laboratory found this unanticipated behavior while studying how oxygen interacts with reduced titanium oxide surfaces. The chemists are trying to understand how molecular oxygen -- the stuff we breathe -- interacts with metals and metal oxides, which are used as catalysts in a variety of environmental and energy applications.

LONDON, February 8 /PRNewswire/ -- NHS Choices (http://www.nhs.uk), the online 'front door' to the NHS, launches a daily health news service to help people make sense of the stories appearing in the news about medical research.

Behind the headlines, on NHS Choices (http://www.nhs.uk/News/Pages/NewsIndex.aspx), is an evidence-based analysis of health stories that make the news. The service explains the facts behind newspaper headlines and an understanding of the science. It also provides an authoritative resource for General Practitioners, which they can rely on when talking to patients, and a trusted resource for journalists.

Forty years ago, mathematician Mark Kac asked the theoretical question, "Can one hear the shape of a drum?"

If drums of different shapes always produce their own unique sound spectrum, then it should be possible to identify the shape of a specific drum merely by studying its spectrum, thus "hearing" the drum's shape (a procedure analogous to spectroscopy, the way scientists detect the composition of a faraway star by studying its light spectrum).

But what if two drums of different shapes could emit exactly the same sound?

A report published in BMC Public Health states that socio-economics and neighborhood have a more powerful influence on sexual activity among 15- and 16-year-olds than the classroom.

A team of researchers analyzed data on nearly 5,000 pupils from 24 different Scottish Schools. They found that overall 42% of girls and 33% of boys reported experience of sexual intercourse, but the rates between schools ranged widely, from 23% to 61%.

Commenting on the value of sex education in schools, lead author Dr. Marion Henderson said, "It would be over-simplifying to interpret these results as suggesting that sex education isn't valuable. The study was looking at effects of school beyond the sex education curricula."
