daveschroeder writes “After a marathon debate over a pair of studies that show how the avian H5N1 influenza virus could become transmissible in mammals, and an unprecedented recommendation by the National Science Advisory Board for Biosecurity (NSABB) to block publication, and its subsequent reversal, a study by Yoshihiro Kawaoka at the University of Wisconsin–Madison was finally and fully published today. ‘Experimental adaptation of an influenza H5 HA confers respiratory droplet transmission to a reassortant H5 HA/H1N1 virus in ferrets’ appears in the journal Nature.”

Tribute To Steve Jobs: a 21km Apple Logo in Tokyo

Japan

An anonymous reader writes “To pay his tribute to Steve Jobs, Joseph Tame, a media producer and a marathon runner from Tokyo, ran 21 kms in 2 hours — starting from the western side of the Imperial Palace, across to Roppongi, through Omotesando, then up to Shinjuku. The leaf is in Kagurazaka, and the start/finish point just by the entrance to Yasukuni Shrine. The route, when mapped, shows the famous Apple logo in the center of Tokyo.”

gregg writes “Five knee-high androids have crossed the starting line in the world’s first marathon for two-legged robots.The contestants are expected to take four days to complete the course, which involves 423 laps of an indoor track.” The live robot marathon video feed will make you realize that not all robots are worthy of fear. Or even worth watching for more than a few minutes.

Running by the Books: Math for the Marathoner

October 22nd, 2010 10:39 admin View Comments

marathonerAbout two-fifths of marathon runners “hit the wall” on the big day. That means they completely deplete their body’s stash of readily available energy, which makes them feel wiped out and severely limits their running pace; it sometimes forces people out of the run completely.

Marathoner and biomedical engineer Benjamin Rapoport has been physically and mentally struggling with this phenomenon for years, and had the bright idea to turn it into a research project. He published a mathematical theory in the journal PLoS Computational Biology describing how and why runners hit the wall–and how they can avoid it.

By taking into account the energy it takes to run a marathon, the body’s energy storage capacity and the runner’s power, the researchers were able to accurately calculate how many energy-rich carbohydrates a runner needed to eat before race day and how fast to run to complete all 26.2 miles (42 kilometers). [LiveScience]

Rapoport’s studies of marathoners were prompted by his desire to run in the Boston Marathon in 2005, and his teacher’s desire for him to be in class. In return for missing class, Rapoport was tasked with giving a class lecture on the physiology of the marathoner. That same year, Rapoport himself hit the wall while running the New York Marathon.

“It feels a bit like you might feel if you’re on a crash diet,” Rapoport said. “Except that when you diet, it happens over the course of a few days, whereas a runner experiences it in the course of a few minutes.” [LiveScience]

The main limitation of a marathon runner’s ability is his or her aerobic capacity–how much oxygen the muscles can take up and keep working. The other important factors are how much energy is takes the person to run, and how much energy they have stored in an easy-to-access form, glycogen. By using estimations of these numbers, Rapoport was able to create a mathematical model of how long and fast any runner could run and how much they would need to fuel up in order to finish the race.

“This is a unique area that hadn’t been addressed in the medical literature in any substantial way,” says Mark Cucuzzella, a physician and running coach based in Harpers Ferry, W.Va. “He’s lending some hard numbers to what experienced runners and coaches have been doing.” [Science News]

By estimating their aerobic ability and other factors in the model, runners can estimate what their pace should be to complete a marathon in the best time.

Rapoport’s model also shows that a slightly faster pace can be maintained by consuming a midrace snack. This carb-eating strategy can help, but it can’t win races, since the body can store only so much fuel, says Cucuzzella, chief medical consultant for the Air Force Marathon and a marathoner himself. “It’s not about how much sugar or spaghetti you eat the night before a race,” he says. “There’s a critical pace.” [Science News]

And while following this formula won’t enable everyone to run a marathon without training, Rapoport has put an easy-to-use version of his unwieldy formula online to help trained runners calculate their ideal pace.

Aussie Army Trains With Fleet of Robots On Segways

April 12th, 2010 04:18 admin View Comments

kkleiner writes “The armed forces of the world have already begun to hunt down and shoot robots. No, it’s not the beginning of the man-machine war; it’s a state-of-the-art training simulation that’s very cool to watch. Australia-based Marathon Robotics has taken Segways and turned them into human-shaped autonomous robots capable of moving around streets and buildings just like people in a crowd! The Marathon bots can act like insurgents, hostages, or civilians, letting armed soldiers practice before being exposed to the real thing. The Australian Department of Defense already has a training camp using the robots, and the US Marine Corps will be establishing one this year.”
