Engineers at MIT developed an electric, shareable car that would fold to conserve parking spaces. A prototype was made for production in Europe. But why did this promising auto never hit the road?

Methane, the primary component of natural gas, is also a potent greenhouse gas, trapping energy in the atmosphere. Last year NASA released satellite images showing a hot spot in the area where New Mexico, Colorado, Utah and Arizona meet, prompting scientists to go in search of the sources. Special correspondent Kathleen McCleery reports on efforts to crackdown on methane emissions.

If you've heard of fusion energy, you've probably heard of tokamaks. These doughnut-shaped devices are meant to cage ionized gases called plasmas in magnetic fields while heating them to the outlandish temperatures needed for hydrogen nuclei to fuse. Tokamaks are the workhorses of fusion—solid, symmetrical, and relatively straightforward to engineer—but progress with them has been plodding. Now, tokamaks' rebellious cousin is stepping out of the shadows... By Daniel Clery.

The song is so catchy

Starting November, the pyramids of Giza will be subject to a non-invasive survey in an attempt to unravel their secrets four millennia after their construction.

The team from Stevens Institute of Technology of Hoboken, New Jersey – inspired by Hurricane Sandy to design and create a net-zero home resilient enough to withstand hurricane-force winds and flooding – won top honors at the U.S. Department of Energy Solar Decathlon 2015.

Germany’s new stellarator was “hell on Earth” to build, but it will be worth it—if it works

Their machine, the Delta Flume, works like this: Pistons rhythmically shove around more than two million gallons of water in a 900-foot-long concrete trough, like a giant toddler splashing back and forth in a bathtub. Eventually, the waves double back on themselves to form monsters up to 15 feet high.

The design challenge of the space suit was handed to a small team inside NASA - Crew Systems. The leader of their team was Matthew Radnofsky, known as "the Mad Russian" - an eccentric second-generation Jewish immigrant with a can-do attitude and a broad Boston accent. His granddaughter, Caroline Radnofsky, set out explore the legacy of her grandfather, the man behind the iconic Apollo 11 space suits.

If the Mjolnir were real, most of us would probably never be able to lift it. We'll bet Allen Pan wouldn't care one bit, though: not when he can easily make his own. The electrical engineer who likes making "pretend things into real things," according to his YouTube channel Sufficiently Advanced, has recreated Thor's hammer.

2015 has been the ‘Year of The Battery,’ but it’s time to focus less on cost and more on the value.

Draw working circuits in pen and ink, Seriously!

Above 50mph, this svelte four-door alters its form to cheat the wind.

Could an airliner that flies anywhere in under three hours be in service by 2030? “It is a magic aircraft… the pleasure of flying in it is almost a carnal one.” So said Joelle Cornet-Templet, a chief stewardess for Air France, about Concorde: one of the world’s first supersonic civilian airplanes, which flew from 1976 to 2003 and became a watchword for travelling in style.
