A Failed Lab Experiment Accidentally Invented a Replacement For Cement

As the world’s cities expand at faster and faster speeds, so does its use of cement. One oft-quoted statistic shows that China alone used as much cement in the last three years as the US used in the last 100. Just one problem: Cement is responsible for pushing a hell of a lot of carbon dioxide into the world. » 4/16/15 4:29pm Thursday 4:29pm

Study Suggests Magnetic Fields Can Control Heat And Sound

More than a hundred years ago, physicists discovered that heat is simply the energy stored in the vibrations of atoms. This meant that heat and sound are related. Now, for the first time ever, scientists have experimentally shown that these atomic vibrations have magnetic properties, too. » 3/25/15 11:40am 3/25/15 11:40am

UMass Has Banned Iranian Students from Engineering and Science Programs…

Starting this month, the venerable University of Massachusetts at Amherst will no longer allow Iranian nationals to matriculate as graduate students in many of its programs in engineering and the natural sciences, including physics and electrical/computer engineering. » 2/17/15 3:30pm 2/17/15 3:30pm

This Huge Engineering Project May Be Our Best Chance At Colonizing Space

Space colonization has reached an impasse, for reasons far more fundamental than a lack of money for the Space Shuttle program. There is simply no way humans can travel easily offworld without using massive amounts of rocket fuel to escape the gravity well — and that's both expensive and environmentally… » 2/04/15 11:30am 2/04/15 11:30am

High-Speed Video Reveals The Source Of That Incredible After-Rain Smell

That smell has a name. It's called petrichor. For decades, scientists have speculated on where this smell comes from, but the mechanism behind the phenomenon has remained elusive. Now, researchers at MIT studying high-speed video of raindrops think they've found the answer: The smell is released in tiny aerosol clouds… » 1/15/15 5:30pm 1/15/15 5:30pm

Watch A Pair Of Tank-Mounted Fighter Jet Engines Extinguish An Oil Fire

Pretty much what it says on the tin, folks. "The Big Wind" is a colossal, roving fire-extinguisher of Hungarian design that combines one part T-34 Soviet tank with two parts MiG-21 turbine engine. Bring it all together, add a trio of operators, and you've got a Mad-Maxian chimera that can gush water at a rate of 220… » 12/28/14 9:30am 12/28/14 9:30am

MIT Students Build Handmade Wooden Roller Coaster For Incoming Freshmen

The coaster was designed by three mechanical engineering juniors and built in the span of a week by the incoming freshmen who would ride its wooden rails. In early designs, the coaster even had an internal loop. Unfortunately, MIT's Environment Health and Safety department said "no upside-down people. Period." » 12/27/14 7:48am 12/27/14 7:48am
