Olympic boxing scoring is fair

For eight solid minutes, U.S. Olympic team light flyweight Luis Yanez traded punches with Spain's Kelvin de la Nieve. Yanez, 19, came out on top in his match, cleanly landing 12 punches to nine for his opponent.

At least that was the final score according to the five judges who monitored the fight. With counterpunches flying, it can be difficult to determine who scores and when.

Under Olympic scoring rules, each judge has two buttons — a red one for the boxer in the red corner, a blue one for the boxer in blue. For a point to be registered, three of the five judges must press the same button within one second of one another. read more

Olympic swimmers are clocking times milliseconds faster at the 2008 Summer Olympics in Beijing

Olympic swimmers are clocking times milliseconds faster at the 2008 Summer Olympics in Beijing thanks in part to engineers at Rensselaer Polytechnic Institute.

Using a technology called Digital Particle Image Velocimetry (DPIV), a team led by Tim Wei, an aerospace engineering professor at RPI (Troy, N.Y.), was able to pinpoint trouble spots for U.S. swimming coach Sean Hutchison, who used the information to alter his swimmers' strokes and cut their times.

"For the first time we have learned how to apply the principles of fluid mechanics to improve the way swimmers move through the water," said Wei, who worked with U.S. swim team's biomechanics manager, Russell Mark, on the project. read more
