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?

The February issue of Geotimes takes a look at the complicated issues surrounding Iraq’s oil exploration and production.

Though oil prices have doubled and Iraq boasts the largest untapped oil reserves in the world, the instability that comes with war, attacks on infrastructure and outdated technology in Iraq have led to the lowest reserve-to-production ratio of all oil-producing countries.

Currently Iraq produces 2.0 million barrels per day (bpd), down from an average of 2.6 million prior to the invasion in 2003. Exploration and development in Northern Iraq could easily increase production by 100,000 bpd.

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."

National Science Foundation (NSF) Director Arden L. Bement Jr. has presented the agency's proposed $6.85 billion budget for fiscal year (FY) 2009, a 13 percent increase over its actual FY 2008 budget. The additional $822.10 million would increase funding for agency programs that advance the frontiers of research and education in science and engineering.

Bement said the increase reflected a growing consensus that the United States needs to invest more resources in basic scientific research if it is to remain a global leader in science and technology. "More than a dozen major studies have now concluded that a substantial increase in federal funding for basic scientific research is critical to ensure the preeminence of America's scientific and technological enterprise," Bement said.

The colugo doesn't fly and is not a lemur but it's still called a "flying lemur" - and it's the champion of all gliding mammals, able to drop from the forest canopy in Malaysia, glide more than the length of two football fields, execute 90-degree turns and then alight gently on a tree trunk.

The colugo looks like a very large squirrel with membranous skin stretching from each limb and even between its toes to catch the wind and work as a parachute. When fully spread, the skin flaps reach the size of a large doormat.

Researchers are discovering how these animals move with the help of a miniature backpack outfitted with accelerometers.

Collaboration is a requirement for the advancement of modern science. Researchers cannot be expert at everything and must specialize to make a unique contribution. But if coordinating research within a group is challenging, effective collaboration between groups is even more so. There is often a strong temptation for research units to treat each other like black boxes. There is some logic to this - the point of having a collaborator is to distribute the responsibility of tasks in a project. If I get involved with every detail of my collaborator's work I may as well do the work within my own group. But problems can arise because of unstated assumptions between groups.
