- 'Dipstick' test could reduce risk of food poisoning by rapidly detecting spoilage
03-25-2007 · EurekAlert!
Chemists at the University of South Carolina are developing a consumer test kit that people can use to quickly and accurately determine if food products are spoiled or safe to eat. The disposable 'dipstick' test is capable of rapidly (less than five minutes) detecting the presence of chemicals formed by disease-causing bacteria. The test, which could save lives, will be described in March at the American Chemical Society national meeting in Chicago.

- Unpeaceful co-existence: How strengths and weaknesses maintain biodiversity in an ant community
02-08-2007 · EurekAlert!
Many species of ants scavenge for the same food, but the single most efficient species doesn't drive the others to extinction. Adler et al. modeled this unpeaceful co-existence. Some species are better at finding food while others are better at defending it. Some ants are efficient at both but flee when their own enemies (parasitoid flies) arrive.

- Ring-around-the-cell
03-27-2007 · EurekAlert!
Breaking down bone is a tough job; however, our bones undergo remodeling every day. In diseases such as osteoporosis, an imbalance in this process is responsible for bone loss. New research reveals how osteoclasts move around the bone until they reach a site where their services are required, at which point they undergo a transformation called polarization. The polarized osteoclast sticks tightly to the bone, while an impermeable ring forms around the cell perimeter.
