Photo of the Alice miniature robot, developed at the Swiss Federal Institute of Technology in Lausanne, is superimposed on a scene of fire ant activity. Massive Fishery Resurfaces in Amazon Native groups in an Amazonian region of Bolivia built a large-scale fishery and other earthworks at least 300 years ago, before the Spanish conquest. This fly's ears can rival a cat's The unusual eardrums of a tiny parasitic fly turn out to rival cats', owls', and people's abilities to pinpoint the origin of a sound. Although the space station's main laboratories have yet to be launched, scientists are already using nooks and crannies in the existing structure to conduct experiments in biotechnology and physics. A new malaria vaccine tested in chimpanzees spurs an immune response against the parasite as it passes through the liver, halting it in most cases before it can get into the bloodstream and cause symptoms of the disease.
Ant teamwork suggests models for computing faster and organizing better.
These immune molecules may directly kill, not just tag, microbes. The last ice age wasn't totally icy Radiocarbon dating of fossils taken from caves on islands along Alaska's southeastern coast suggest that at least a portion of the area remained ice-free during the last ice age. Allosaurus fragilis can resist levels of stress much higher than those expected from chewing, which may provide insight into the animal's method of attacking its prey. Researchers have unearthed fossils of a theropod dinosaur whose front teeth grew almost directly forward, which sets it apart from all other related species. All rights reserved.
