Article: An annoying problem for humans, who like to boast about all the distant planets and moons we have explored, is that we've never taken a good look right under our noses. The inside of the earth is relatively close, but how can we get there? The deepest oil well enters a mere six miles into the crust (the center of the earth is about 4,000 miles deeper). Russian scientists dug the deepest hole in Siberia, but bottomed out at about 7.5 miles below the surface. The Mohole project, a U.S. plan in the 1950s, called for drilling a hole 25 miles down to the boundary between the hard rocks of the crust and the soft mantle . Sadly the project involved government supporting. It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust --- about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible. What little we know about the inside of the earth (like the fact that there's a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes. So maybe it's time for a thorough new method to explore the earth's inside. Scientist David Stevenson says we should forget about drilling holes. Instead, we should open a crack . Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb. Next, he'd pour a few hundred thousand tons of molten iron into the crack, along with a robot. The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper. The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the surface. Stevenson compares his idea to space exploration. "We're going somewhere we haven't been before,"he says. "In all possibility, there will be surprises." This idea can probably be put in the drawer marked with Isn't Going To Happen. The robot would have to survive temperatures that would melt pretty much anything. But Stevenson's idea may inspire a new look at an old problem. Great things can come from what seems like impossible ideas.

Article: Eighteen-year-old Dana Kiger is happily running after balls on the soccer field. But not long ago, she couldn't remember her love of the game, her parents' faces or even her name. At 16, the Tennessee honor student and star athlete was hit from behind while playing in a soccer game. She fell to the ground, her head striking the hard ground. The blow knocked out nearly all of Kiger's memories. With no physical injury or unusual change in her brain, doctors thought Kiger's memory would return in a few days. But it did not. And two and a half years later, it still hasn't. Kiger--who has no memory of her family, her childhood or her life before her injury--has had to create new memories, restart relationships and relearn old skills. "The only thing I had ...I could walk, write, but I didn't know what to write," Kiger said of the days after the accident. "Physically, I was OK, I guess, but mentally I was troubled." Doctors say long-term amnesia brought on by a less severe brain injury like Kiger's is unusual. "It's very rare for people to have this lasting problem with memory recovering," said Dr Roger Hartl at Weill Cornell Medical College. Kiger's parents tried to help their daughter return to the life she once lived. "She didn't know what food was," Kiger's mom said. "She said, 'What is that?' I said, 'Lettuce." She said, 'Do I like it?' I said, 'That's up to you to decide.'" Kiger's natural ability on the soccer field was the one part of her earlier life that died immediately. And soon, she'll begin a new life at Slippery Rock University, where she plans to study physical therapy . Kiger said that while parts of her past still remain a mystery, she's focused on what's to come. "It is about my future," she said.

Article: To the untrained eye it might seem like just a bit of a monkey trick. But when Milly the mandrill (, ) covers her face with her hand she is actually sending a serious message to her fellows: "Leave me alone!" Experts believe the 15-year-old mandrill invented the gesture to warn other monkeys at Colchester Zoo to give her some space. And, surprisingly, the signal has been picked by other members of the group, who use it when they too require _ . Biologist Mark Laidre believes the behavior is evidence of social culture among the mandrills. Importantly, the sign language is unlikely to have been influenced by human activities because mandrills do not copy humans. Mr. Laidre expects further research will uncover other monkeys using cultural gestures -- the ability to communicate with the hands in a meaningful way. "By covering their eyes with their hands, possibly conveyed to others that they wanted to be left alone and this message may have been respected as a 'do not disturb' sign," said Mr. Laidre. While the hand is in place, other monkeys are not likely to approach or touch the monkey. Those who rank lower in the social order also use the technique to avoid attacks from more powerful group members. As the discovery appears to be unique to Colchester Zoo, it suggests it is a local phenomenon that arose naturally in the community of 25 mandrills. Curator Sarah Forsyth said: "We believe Milly made up the signal and over the past five years some of the younger mandrills have picked it up. We're not sure why she started doing it but it could be as simple as 'I can't see them, so they can't see me'. It really does show you how intelligent mandrills are."
