Dimmu Borgir. Small Spiders Have Big Brains That Spill Into Their Legs. They're not fat, they're just big-brained: Tiny spiders have such huge brains for their body sizes that the organs can spill into the animals' body cavities, a new study shows.
Such big brains may explain why very small spiders—some less than a millimeter across—are just as good at spinning webs as bigger arachnids. (See pictures: "World's Biggest, Strongest Spider Webs Found. ") For the study, a team led by Bill Eberhard, a staff scientist at the Smithsonian Tropical Research Institute and a professor at the University of Costa Rica, examined nine spider species from six web-weaving families. The researchers found that the smaller the spider, the bigger its brain relative to its body size. In some spiders, the central nervous system took up nearly 80 percent of the space in their bodies, sometimes even spilling into their legs. Big Cat Cub Pictures. Photograph by Beverly Joubert An African lion cub rests in the tall grasses of Botswana’s Okavango Delta.
Once ranging across the African continent and into Syria, Israel, Iraq, Pakistan, Iran, and even northwest India, lions have declined to as few as 20,000 animals from about 450,000 just 50 years ago. Big Cats Initiative National Geographic is working to avert the extinction of lions, tigers, and other big cats with the Big Cats Initiative, a comprehensive program that supports innovative projects. Cyborg search-and-rescue insects' power source unveiled. 24 November 2011Last updated at 15:51 The research team proposed putting two spiral energy harvesters on either side of a beetle's thorax Efforts to create an army of cyborg insects are being pursued by a team of US-based engineers.
The group is investigating ways to harvest energy from the creatures to power sensors and other equipment fastened to their bodies. The team has created an energy scavenging device that is attached close to the insects' wings. It suggested the creatures might one day be used to aid search-and-rescue operations and surveillance. The University of Michigan team of engineers published their study in the Journal of Micromechanics and Microengineering. Power source. Nasa's new mission to establish if there is life on Mars.
