Toy-Sized Robot Completes the Ironman Triathlon

by Zach Lynn

By Zach Lynn, Carleton College The Ironman Triathlon in Hawaii is known for its rigorous difficulty. Competitors must complete a 2.4 mile swim, a 180 mile bike ride, and a 26 mile (marathon) run. In 2011's Ironman Triathlon, Mr. Evolta, a 6.7 inch tall robot, raced alongside human competitors. It finished in 166 hours and 56 minutes, just under its goal of 168 hours (one week). The average time for a human competitor is about 10 hours. The lead designer of Mr. Evolta, Tomotaka Takahashi, reasoned that since the robot was about one tenth the size of a man, it should take the robot 10 times as long to complete the course.

Possible Plastic Alternative Inspired by Insects

by Zach Lynn

By Zach Lynn, Carleton College Plastic's environmentally hazardous reign of terror over consumer products might be about to end. The Wyss Institute for Biologically Inspired Engineering at Harvard University has just developed a cheap, sturdy and biodegradable material that could realistically act as an alternative to plastic. This material, known by its creators as "Shrilk", was inspired by the sturdy yet flexible cuticles of arthropods (including insects, arachnids and crustaceans).

Experiments at CERN Begin to Pinpoint the Higgs Boson

by Zach Lynn

By Zach Lynn, Carleton College  Yesterday, two research groups, both based at CERN in Geneva, Switzerland, presented the latest data from the search for the Higgs boson. Although it is far from definitive, their results suggest that the Higgs boson does, in fact, exist. The experiments have pinpointed a range of masses that it might inhabit. Confirmation that the Higgs boson does or does not exist will have significant consequences in particle physics.

Neutrinos May Be Able to Exceed the Cosmic Speed Limit

by Zach Lynn

Zach Lynn, Carleton College  This September, the OPERA experiment (Oscillation Project with Emulsion-tRacking Apparatus) announced that they had observed a pulse of neutrinos moving faster than the speed of light. The difference wasn't large. The neutrinos arrived at the detector in Gran Sasso, Italy about 60ns (60 billionths of a second) faster than a photon in a vacuum would have. The neutrinos appeared to be moving about 1/40,000 times (about 17,500mph) faster than the speed of light.

Science Keeps Sandwich Fresh for Two Years

by Zach Lynn

By Zach Lynn, Carleton College Since 1966, the US Army has been providing its troops in the field with Meals Ready to Eat or MREs. MREs are "completely self-contained meals that provide all the nutrition a solider-on-the-go needs to sustain him/herself." As of this year, there are 24 different entrees including options like chili and cheese tortellini. The science that goes into producing these meals is quite impressive.

by Zach Lynn

Today, December 1st, is the 24th annual World AIDS Day. Each World AIDS Day has a theme and 2010's is "Universal Access and Human Rights." For Americans, this should serve as a reminder that although AIDS related deaths have declined in the United States, AIDS is global health issue. About 33 million people, including over 2.5 million children, are living with HIV or AIDS.
