New state of consciousness?
<p></p><p> With anesthetics properly given, very few patients wake up during surgery. However, new findings point to the possibility of a state of mind in which a patient is neither fully conscious nor unconscious, experts say.</p><p> This possible third state of consciousness, may be a state in which patients can respond to a command, but are not disturbed by pain or the surgery, according to Dr. Jaideep Pandit, anesthetist at St John's College in England, who discussed the idea today (Sept. 19) at The Annual Congress of the Association of Anaesthetists of Great Britain and Ireland.</p><p>[Full Story: <a href="http://www.livescience.com/39812-strange-consciousness-state-in-surgery.html" target="_blank">

Map of Bigfoot sightings created
<p></p><p> Reported sightings of Bigfoot — the legendary apelike creature that's been a favorite of cryptozoologists for decades — have abounded for decades. Now, for the first time, someone has created a map showing the places where alleged Bigfoot sightings have occurred.</p><p> Joshua Stevens, a doctoral candidate at Pennsylvania State University, used data compiled by the Bigfoot Field Researchers Organization (BFRO), which tries to document "the presence of an animal, probably a primate, that exists today in very low population densities," according to the group's website.</p><p>[Full Story: <a href="http://www.livescience.com/39785-bigfoot-map-sasquatch-sightings-gis.html" target="_blank">

Biblical-era town discovered
<p></p><p> A town dating back more than 2,000 years has been discovered on the northwest coast of the Sea of Galilee, in Israel's Ginosar valley.</p><p> The ancient town may be Dalmanutha (also spelled Dalmanoutha), described in the Gospel of Mark as the place Jesus sailed to after miraculously feeding 4,000 people by multiplying a few fish and loaves of bread, said Ken Dark, of the University of Reading in the U.K., whose team discovered the town during a field survey.</p><p>[Full Story: <a href="http://www.livescience.com/39661-biblical-era-town-discovered-sea-of-galilee.html" target="_blank">Biblical-Era Town Discovered Along Sea of Galilee</a>]</p>
Earth's habitable life span calculated
<p></p><p> Earth could continue to host life for at least another 1.75 billion years, as long as nuclear holocaust, an errant asteroid or some other disaster doesn't intervene, a new study calculates.</p><p> But even without such dramatic doomsday scenarios, astronomical forces will eventually render the planet uninhabitable. Somewhere between 1.75 billion and 3.25 billion years from now, Earth will travel out of the solar system's habitable zone and into the "hot zone," new research indicates.</p><p>[Full Story: <a href="http://www.livescience.com/39775-how-long-can-earth-support-life.html" target="_blank">

Snake robots for Mars?
<p></p><p> Mechanical "snake robots" could boost the scientific output of next-generation Mars rovers and get them out of jams from time to time, researchers say.</p><p> Small, serpentine robots could help Mars rovers collect soil samples from crevices beneath rocks and other hard-to-reach places, and they could pull their wheeled siblings to safety if the bigger vehicles get bogged down in soft sand.</p><p>[Full Story: <a href="http://www.livescience.com/39818-snake-robots-mars-rovers.html" target="_blank">

What triggered evolution's big bang?
<p></p><p> The Cambrian explosion, the evolutionary "big bang" that led to the emergence of a trove of complex life forms, was caused by multiple events, researchers argue.</p><p> Genetic changes allowing for complex body plans combined with rising sea levels and an influx of chemicals into the ocean probably created the unique conditions needed to set off the Cambrian explosion, researchers argue in a perspectives paper published today (Sept. 19) in the journal Science.</p><p>[Full Story: <a href="http://www.livescience.com/39790-cambrian-explosion-had-multiple-causes.html" traget="_blank">

Termites use poop to …
<p></p><p> Termites may use their own poop as a source of natural antibiotics, researchers say.</p><p> These findings might help explain why human attempts to kill them using biological warfare have failed over the past 50 years, scientists added.</p><p>[Full Story: <a href="http://www.livescience.com/39729-termite-poop-carries-antibiotics.html" target="_blank">

Whale earwax reveals life history
<p></p><p> A blue whale's buildup of earwax archives its history of stress levels and exposure to chemical pollutants, which could allow researchers to piece together new details about the animal's life, a study shows.</p><p> The blue whale is the largest animal on Earth, and an endangered species. Like many other baleen whales, these massive creatures tend to accumulate layers of wax in their ear canals, which over time results in long earplugs.</p><p>[Full Story: <a href="http://www.livescience.com/39727-blue-whale-earwax-chemical-archive.html" target=_blank">

Do goldfish prefer Bach or Stravinsky?
<p></p><p> Goldfish may be more refined than people give them credit for. A new study shows the fish can distinguish between the works of Johann Sebastian Bach and Igor Stravinsky.</p><p> The study may seem strange, but the results actually add to a growing body of research showing that a variety of animals can distinguish between different composers and musical genres, and sometimes appear to prefer one to another.</p><p>[Full Story: <a href="http://www.livescience.com/39692-goldfish-bach-stravinsky.html" target="_blank">

Female squid wear fake testes
<p></p><p> The females in one species of squid may have a natural defense for escaping unwanted male attention: special light-reflecting cells that can create the illusion of testes.</p><p> Like many of its cousins, the opalescent inshore squid (<i>Doryteuthis opalescens</i>) of the Eastern Pacific Ocean is equipped with shimmery cells on its body that can change color for camouflage and communication.</p><p>[Full Story: <a href="http://www.livescience.com/39687-female-squid-fake-testes.html" target="_blank">
