Technology is blurring the lines between civilian and military satellites. With countries testing anti-satellite weapons, how much of a threat is war in space? Saadia Pekkanen, professor of international studies at the UW, is interviewed.

New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads, lining a cartilaginous appendage called the tenaculum, in addition to those in their jaws. They used their tenaculum teeth to grip females while mating in water.

Physicists have floated numerous theories to explain what dark matter might be, but to date, no experiment has turned up compelling evidence to support any of them. An international team of physicists, including researchers from the UW, is now working on a new kind of dark matter detector with the goal of capturing the first direct observation of the puzzling material. Results from the detectors prototype have already ruled out one of the leading theories of how dark matter originated.

Heading back to school Wednesday, students in the Northshore School District will pack their books, pens, and paper, but not their cell phones.Its just one of many Washington state school districts that now have a district-wide policy for mobile devices.Luca Magis-Weinberg, assistant professor of psychology at the UW, is quoted.

A growing number of school districts are implementing new cell phone bans in the classroom, and a University of Washington study found that while teachers generally support the policies, students are less positive, though some concede the policies improve concentration. Luca Magis-Weinberg, assistant professor of psychology at the UW, is interviewed.

Its been seven years since Pacific Seafood stopped trying to grow oysters on a particular mudflat on the Washington coast. Two years since the Washington Department of Natural Resources last experimented with killing the shrimp infesting it by compacting the sediment with an amphibious, tracked vehicle known as the Marshmaster. Jennifer Ruesink, professor of biology at the UW, has been monitoring the ground ever since. But the latest round of funding for the project will be drying up at the end of the month, and this trip will be her last. Haleh Mawson, research scientist in biology at the UW, is also mentioned.

A city program that gives low-income households $40 a month to buy fruits and vegetables significantly improved their food security, a new University of Washington study found. Melissa Knox, UW teaching professor of economics, is quoted.
