In 1960, Colonel Joseph Kittinger jumped out of a helium balloon at 102,800 feet in the name of science, setting the world record for the highest and fastest parachute jump. Later this year, an Austrian daredevil named Felix Baumgartner
hopes to beat that record by more than 3 miles, also by stepping out of a balloon. From Space.com:
"Right now, the space shuttle escape system is certified to 100,000 feet," said the mission's medical director Jonathan Clark, a former NASA flight surgeon. "Why is that? Because Joe Kittinger went there. You've got a lot of companies that are vying for the role of being the commercial space transport provider for tourism, for upper atmospheric science, and so on. These systems, particularly during the test and development phase, need a potential escape system, which we may be able to help them provide with the knowledge we gain."

A team of aeronautics experts recently led Baumgartner through a week of testing meant to illuminate any possible weaknesses in his equipment and to familiarize him with the skills needed to navigate the conditions expected to assail him as soon as he opens his vessel door.
Only a few feet above ground in a capsule dangling from a crane on Sage Cheshire Aerospace test grounds in California, Baumgartner practiced exiting and stepping off his hot-air balloon. Even a slight stumble during this step could cause dangerous alterations in his in-flight position only moments later, as well as reduce his chances of actually breaking the sound barrier.
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
Biologist Nipam Patel and his team at UC Berkeley study how butterflies develop wing shape and color by performing surgery on caterpillars, creating translucent windows in their cocoons.
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
