More years passed than I care to acknowledge before the practice of perching on a shopping cart and zooming through the grocery store got old. In fact, it never got that old. Not to me, and evidently, not to these MIT students.

According to gadget blog Gizmodo, a group of MIT students recently fashioned a go-kart out of a shopping cart using a stack of NiCd aircraft batteries, a 15hp brushless motor, and some new wheels. The best (read: scariest) part? It can reach 45 miles per hour.

I don’t think they’ve taken it to any grocery stores, though they did record a charming tour of campus. Check it out on YouTube or view below:

The formation of a phantom traffic jam.

The formation of a phantom traffic jam.

The most frustrating sort of traffic jam may be the one that has, apparently, no cause. Think road rage with no one to blame.

MIT mathematicians have been working on the problem. No, they didn’t find someone to blame. Instead, they have developed a model that describes the circumstances that prompt such jams to form. This model could help road designers minimize the odds of their formation. The model can also help determine safe speed limits and identify stretches of road where high densities of traffic—hot spots for accidents—are likely to form

The mathematics of such jams, which the researchers call “jamitons,” are strikingly similar to the equations that describe detonation waves produced by explosions, says Aslan Kasimov, lecturer in MIT’s Department of Mathematics. The equations, similar to those used to describe fluid mechanics, model traffic jams as a self-sustaining wave.

Vikram Sahney SM ’05, MBA ’05 started getting serious about climbing in 2002, when he took a six-day glacier mountaineering course. He did his “first respectable climb,” summiting 14,411-foot Mount Rainier, while doing his MIT internship in Seattle in 2004. In May, he reached the ultimate summit— Mount Everest, the world’s tallest mountain at 29,035 feet.

“I think the best thing about mountain climbing is that is gives me perspective on daily life,” said Sahney, who works as an engagement manager at McKinsey & Co. in Seattle.

Sahney earned his degrees in an MIT program designed for manufacturing professionals. Created in 1988 as Leaders for Manufacturing, the program was renamed Leaders for Global Operations (LGO) in June. LGO students earn two degrees in two years: either master’s in management and a second master’s in an engineering field.

See the view from Mount Everest in a movie clip by Val Hovland ‘98, SM ‘98, who completed the climb this spring.

OliVaylle olive oilAs a retiree in Australia, former civil engineer Jorge de Moya ’53 happened upon an olive oil production feasibility study from the State of South Australia and did what comes naturally to MIT alums. He dissected it and questioned everything. Back then, not much olive oil was produced Down Under. As late as 2006, Australia contributed only 0.31 percent of the world’s extra virgin olive oil, according to the Australian Olive Association. De Moya’s inquisitive nature took him and his brother, Juan de Moya ’52, on a three-month tour of the major olive oil producers in the Mediterranean, Spain, and the Middle East.

After the journey, De Moya decided there was no reason good olive oil couldn’t be produced in Australia. He also thought he could make a better product than anyone in the world by focusing on ways to combat the factors that can diminish quality: heat, oxygen, time, contaminants, and light. He devised his own production techniques that take just six hours from tree to storage tank. Human hands (which can cause contamination) don’t touch his olives. They are mechanically harvested from trees, and olive oil and paste are protected from oxygen throughout the crushing process. Temperatures are also strictly controlled and lowered to prevent premature aging. Typically, major producers will vacuum olives off the ground and use high temperatures to extract every last drop of oil (a process ironically called cold pressing), which lessens the quality, according to de Moya. His product is also bottled in nearly black glass, to prevent light exposure.

The result is a product de Moya calls OliVaylle, which he claims blows away any competition. He may be right. Earlier this month, it won the gold award at the 4th China International Olive Oil Competition. And the Food Channel asked chefs and olive oil connoisseurs to conduct a taste test. Their unanimous verdict? That it was indeed a superior product. See what they had to say.

The year after Chris Cassidy earned his ocean engineering masters from MIT, he and a team of fellow Navy SEALS were deployed to Afghanistan to try to take down top al-Qaida leader Osama bin Laden. Eight years later, Cassidy is preparing for a new mission: Space.

The 39-year-old father of three will be the second SEAL in space when he takes off in the shuttle Endeavor for the International Space Station. Mission STS-127, for which Cassidy is serving as mission specialist, will last 16 days. One of the main objectives is to complete construction of the Japan Aerospace Exploration Agency’s Kibo laboratory.

The launch, originally scheduled for June 17th, has been delayed twice because of a hydrogen leak. NASA reported on Sunday that a plate that attaches the vent line to the shuttle’s external fuel tank is slightly misaligned, thus causing the tank to leak during fueling.

The new launch date is scheduled for July 11 at 7:39 pm EDT. If you’re interested in keeping up to date about the mission’s progress, check out NASA’s Web site for online updates, or subscribe to the NASA twitter feed.

He was honored for his nanomedicine contributions: a new class of cancer therapeutics and a new paradigm for enhancing drug delivery to tumors.

Stroll down the Stata Student Street to see the InvenTeams Showcase prototypes Thursday and Friday evenings. On Saturday, you can cheer on some 200 high school students working through an all-day design challenge based on wind-powered devices or enjoy the hands-on learning activities for young children at the Museum of Science. Enjoy!

Before the term “computer virus” was common in our daily discourse, it had to be explained to the general public—apparently with a sufficient amount of melodrama and intrigue. Watch this TV newscast from 1988 as it tackles the new threat with lines like, “It arrived at MIT in the middle of the night. The students were safe. Their computers weren’t” and “The suspect? Somewhere, a dark genius.”

Ah, the Eighties. You may also enjoy the retro hardware with actual floppy disk drives and the use of footage from movies and an Atari video game to drive home the seriousness of the situation.

Admit it. You’ve spent more time than you care to admit scrolling through videos online, following one link to the next until (cringe), you’re watching the newest Beyonce music video. Again.

Fortunately Bob Gourley, primary blogger of CTOvision.com, recently amassed a collection of 10 videos that may be good for you and your career. He recommends them to Chief Technology Officers and Chief Information Officers, saying theypresent information we should all be thinking through regarding the future of IT…”

Not surprisingly, the first video features an MIT professor, Pattie Maes, who discusses game changing wearable technology.

Happy First Day of Summer! I figured this would be a good day to officially begin my summer blog, although the recent rain, wind, and cold has made it feel more like October than June. Luckily, this makes me want to be outside less – which is great, as I am never at a loss for indoor activities this summer. That is, when I’m not in lab, coordinating for Camp Kesem, or with friends, I can always be spending my time studying for the MCAT.  :-/ (Outside studying doesn’t work – just ask my freshman-year-self who tried studying on the benches along the Charles. (Not a good idea!))

Compared with my packed summer schedule, things were much different during the two weeks I spent at home in late May. I rediscovered the world of trashy television (particularlyThe Real Housewive’s of Orange County/New York/New Jersey, which I am obsessed with for unknown reasons). Specifically, one evening I sat down with my brother while he was watching The Science Channel, and after a few minutes I insisted he, “put something good on.” I promise I really do go to MIT! 🙂DSC01458

To the right, feast your eyes on my new view for the summer! What was your view like during your time at MIT?
