#Coolest Science Stories of the WeekNASA's next mission to...home? A fly-sized robot? A killer cave in Spain? These stories and more made our top picks for the week.</Click on!</Archaeologists have unearthed evidence that the Jamestown settlers practiced cannibalism.</Researchers excavating at Jamestown fort discovered the mutilated skull and severed leg bone of a 14-year-old girl they have dubbed Jane. The bones were scattered amongst butchered dog and animal bones. Forensic analysis suggests the girl likely died of disease or starvation before she was eaten.</Full Story:<<a href=http://www. livescience. com/29237-jamestown-settlers-practiced-cannibalism. html target=blank>Jamestown Settlers Practiced Cannibalism</a p>When it comes to antimatter what goes up doesn't necessarily come down. In a new study physicists weighed antimatter in an effort to determine how this strange cousin of matter interacts with gravity.</Ordinary matter atoms fall down due to the pull of gravity but the same might not be true of antimatter which has the same mass as matter but opposite charge and spin. Scientists wondered whether antimatter atoms would instead fall up when pulled by gravity and whether such a thing as antigravity exists.</Full Story:<<a href=http://www. livescience. com/29164-antimatter-antigravity-fall-up. html target=blank>Crazy World: Antimatter Might Just Fall Up</a p>Flies have tiny wings and even tinier brains yet they are capable of flying swiftly and agilely through even turbulent air. How do they do it?</And could we create a robot capable of doing the same?</That's the question that's been buzzing around Harvard professor Robert Wood's head for 12 years now. And finally after years of testing and the invention of an all-new manufacturing technique inspired by children's pop-up books Wood and his team at the Wyss Institute for Biologically Inspired Engineering at Harvard university have created a robot the size of a penny that is capable of remote-controlled flight.</Full Story:<<a href=http://www. livescience. com/29292-robotic-insects-controlled-flight. html target=blank>Fly-sized Robot Takes First Flight</a p>NASA's newest rover won't be exploring another planet but will take a look at part of our own. Named Grover (short for Goddard Remotely Operated Vehicle for Exploration and Research) the rover will explore Greenland's ice sheets to better understand how they form and how quickly they may be melting.</The device is powered solar and semi-autonomous and will embark on its first mission beginning tomorrow (May 3) and continuing until June 8. It was developed from 2010-2011 by teams of students in summer engineering boot camps at Goddard Space Flight Center in Maryland according to a release from NASA.</Full Story:<<a href=http://www. livescience. com/29259-nasa-rover-explores-greenland. html target=blank>NASA Rover to Explore...Greenland</a p>In June 1908 a mysterious blast occurred above the remote Russian forests of Tunguska Siberia with 1000 times more power than the Hiroshima bomb flattening trees over an area roughly the size of Tokyo.</The most widely accepted theory is that a huge asteroid or comet (not a UFO or chunk of antimatter) exploded as it entered Earth's atmosphere. But with just one death few witnesses and no fragments nor any impact craters to study scientists have been left to puzzle over what exactly caused the so-called Tunguska event.</Full Story:<<a href=http://www. livescience. com/29258-first-tunguska-meteorites. html target=blank>1st Meteorites from 1908 Tunguska Explosion Possibly Found</a p>A cavern in Spain may have lured ancient carnivores to their deaths by offering the promise of food and water new research suggests.</The new study published today (May 1) in the journal PLOS ONE may explain how the carcasses of several carnivore species including saber-toothed cats and bear dogs wound up in an underground cavern millions of years ago.</Full Story:<<a href=http://www. livescience. com/29241-killer-cave-lured-carnivores. html target=blank>Killer Cave Lured Ancient Carnivores to Their Death</a p>With a gentle pull and a Hi cutie! a doctor pulls a baby from an incision in the mother's abdomen. Within seconds the newborn has launched into a squalling cry. It's a boy!</And Twitter goes wild.</Yes Twitter. This bouncing baby boy made his Internet debut as the star of the first-ever live-tweeted Cesarean section on Feb 20. Though live webcasts and other social media surrounding surgery are not new Memorial Hermann Hospital in Houston elevated the art form by choosing a feel-good procedure the birth of a baby to broadcast. More than 87500 people have viewed the video online since it was posted.</Full Story:<<a href=http://www. livescience. com/29245-social-media-broadcasts-live-surgery. html target=blank>Social Media Broadcasts Live Surgery to the Masses </a p>Not all of New york city's predators are found on Wall street.</Officials with New york's Department of Environmental Conservation (DEC) are planning to survey a lake in Central park for signs of the dreaded northern snakehead fish aka Frankenfish NBCNEWS. com reports.</Full Story:<<a href=http://www. livescience. com/29219-frankenfish-snakehead. html target=blank>Have invaded'Frankenfish New york city?</</a p>Shark embryos cannibalize their littermates in the womb with the largest embryo eating all but one of its siblings.</Now researchers know why: It's part of a struggle for paternity in utero where babies of different fathers compete to be born.</Full Story:<<a href=http://www. livescience. com/29198-shark-embryos-cannibalize-others. html target=blank>Why Shark Embryos Gobble Each other Up In Utero</a p>Like a person gasping for air when it's in short supply living trees make noises when they are running out of water and a team of French scientists is a step closer to pinpointing the noises.</Lab experiments at Grenoble University in France have isolated ultrasonic pops which are 100 times faster than what a human can hear in slivers of dead pine wood bathed in a hydrogel to simulate the conditions of a living tree.</Full Story:<<a href=http://www. livescience. com/29177-tree-drought-sounds. html target=blank>Thirsty Wood's Distress Call Heard in Lab</a p
