Flexible Tactile Sensors Could Help Robots Work Better
A robot's sensitivity to touch could be vastly improved by an array of polymer-based tactile sensors that has been combined with a robust signal-processing algorithm to classify surface textures. The work, performed by a team of researchers at the University of Illinois at Urbana-Champaign, is an essential step in the development of robots that can identify and manipulate objects in unstructured environments. Dropping Nano-anchor
Touch the tines of a tuning fork and it goes silent. Scientists have faced a similar problem trying to harness the strength and conductivity of carbon nanotubes, regarded as material of choice for the next generation of everything from biosensors to pollution-trapping sponges. Coral Reef Fish Larvae Settle Close To Home
In a new study, researchers have managed to uncover the patterns of local dispersion for a small coral reef fish species by employing a combination of inventive tracking techniques. In addition to providing ecological information about one particular fish species, the work suggests ways that the ecology of other fish can be studied and applied to strategies for the maintenance of stable populations. Tracking Orangutans From The Sky
A new aerial method for surveying orangutan densities provides robust estimates of their number and could be used for large-scale surveying of great ape populations in Asia and Africa. Popular Antidepressants Boost Brain Growth, Hopkins Scientists Report
The beneficial effects of a widely used class of antidepressants might be the result of increased nerve-fiber growth in key parts of the brain, according to a Johns Hopkins study being published in the January 2006 issue of the Journal of Neurochemistry. Chemical composition of red giant star with more carbon than oxygen in
Researchers of the University of Granada have conducted the most complete analysis of the chemical composition and evolutionary state of a spectral type R carbon star. The presence of carbon is essential for the possible development of life in the universe, and therefore explaining its origin is of vital importance. New Proteins Detected On Silicone Breast Implants
Scientists in Austria are reporting detection of previously unrecognized proteins that accumulate on the surface of silicone breast implants after implants are in the body. Georg Wick and colleagues say that the proteins may be involved in causing immune reactions in patients from breast implants and other types of silicone implants. Blowing A Molecule To Bits And Calculating What Happens To All The Pie
The first-ever complete quantum-mechanical solution of a system with four charged particles, namely the photoionization of a hydrogen molecule, has been achieved by an international group of collaborators from the University of California, universities in Spain and Belgium, and DOE's Lawrence Berkeley National Laboratory. The computational breakthrough was inspired by experiments at the Advanced Light Source measuring the position and momentum of both electrons and protons resulting from the photofragmentation of molecular hydrogen. Tiny Carbon Nanotubes Show Big Germ-fighting Potential
In nanoscience's version of a David-and-Goliath story, scientists are reporting the first direct evidence that carbon nanotubes have powerful antimicrobial activity, a discovery that could help fight the growing problem of antibiotic resistant infections. Their research is in the area of single-walled carbon nanotubes. Solving A Dragonfly Flight Mystery
Dragonflies adjust their wing motion while hovering to conserve energy, according to a new study of the insect's flight mechanics. The revelation contradicts previous speculation that the change in wing motion served to enhance vertical lift. Physicists came to their conclusions after analyzing high speed images of dragonflies in action. The insects have two pairs of wings, which sometimes move up and down in harmony. At other times the front set of wings flap out of sync with the back set.
