How the octopus forms an elbow
The octopus arm is extremely flexible. Despite the huge evolutionary gap and morphological differences between the octopus and vertebrates, the octopus arm acts much like a three-jointed vertebrate limb when the octopus performs precise point-to-point movements. Researchers have now illuminated how octopus arms are able to form joint-like structures, and how the movements of these joints are controlled.

MANIAC Challenge to stimulate student experimentation in wireless networking
Competitions are motivating, not to mention fun. Also, failure often teaches more than success, and implementation is always more convincing than simulation. Thus, two Virginia Tech electrical and computer engineering faculty members are developing a Mobile Ad Hoc Networking Interoperability And Cooperation (MANIAC) Challenge.

Hold your breath; Plants may absorb less carbon dioxide than we thought
The world's land plants will probably not be able to absorb as great a share of the rising atmospheric carbon dioxide as some models have predicted, according to a new study at the University of Minnesota. The work showed that limitations on the availability of nitrogen, a necessary nutrient, will likely translate to limitations on the ability of plants to absorb extra carbon dioxide.

Older children not smarter than their younger sibs, study finds
A recent study provides some of the best evidence to date that birth order really doesn't have an effect on intelligence. The findings contradict many studies over the years that had reported that older children are generally smarter than their younger siblings.

Snoring can run in the family
Children of parents who snore are three times more likely to snore themselves, according to a new study by researchers at Cincinnati Children's Hospital Medical Center. Furthermore, children who test positive for allergies are twice as likely to snore. The study appears in the April issue of the journal CHEST.

Soggy sands of Mars?
Cracks and fins in the sand in an American desert look very similar to features seen on Mars and may indicate the recent presence of water at the surface.

Monkey-dung study offers clues about land-use, wildlife ecology
Fecal matter of red colobus monkeys collected in western Uganda has yielded a wealth of knowledge about human land-use change and wildlife health and conservation. The main lesson, researchers say, is that the intensity of tree removal translates directly to parasite populations and the risk of infection of their hosts.

Power of speech drives military vehicles
Speech recognition specialist VoxGen has been selected to add speech interface technology to a system, developed for the Department of Defense by Rochester Institute of Technology, which provides for effective maintenance, operations, and engineering support for commercial and military vehicles.
Speech technology will enhance the vehicle preventative maintenance inspections, and will also guide personnel through complex troubleshooting and maintenance procedures.

Lost photos confirm fossil find
The researcher who discovered Paralititan stromeri, one of the most massive animals ever to walk the Earth, now is "picture-positive" about another dinosaur fossil find by a famous German researcher, Ernst Stromer. In a recent issue of the Journal of Paleontology , Washington University's Josh Smith reports the rediscovery of two photographs of the holotype of Spinosaurus aegyptiacus as it was reposited in the Palaontologische Staatssammlung Munchen prior to 1944, and later presumably lost in a bombing.
