A lucky discovery involving lithium-sulfur batteries has a legitimate chance to revolutionize how we power our world.
U.S. nuclear power plants are built to survive external attacks. Even missiles or a commercial aircraft strike would not cause a meltdown or radiation leak.
A community in Austin, Texas is using geothermal energy to keep homes warm in the winter and cool in the summer.
A radical redesign of commercial aircraft, called the flying-V plane, could increase fuel efficiency by 20%, greatly reducing emissions.
At the Great Lakes Shipwreck Historical Society in Michigan, retrieving sunken vessels is the order of the day. Here’s how they do it.
Using cellulose from trees and a synthetic polymer, MIT researchers have created a material that "is stronger and tougher than some types of bone, and harder than typical aluminum alloys."
The natural wonders of Mauritius include the spectacular sight of an underwater waterfall. Here's the science of how it works.
Why power generated through nuclear fusion will be the future, but not the present, solution to humanity's energy needs.
With launch costs dropping and enormous numbers of new satellites filling the sky, can't we just do it all from space?
The decline of global poverty is one of the most important achievements in history, but the end of poverty is still very far away.
Every power source involves trade-offs. Given the challenges of increasing demand and climate change, what is the future of energy?
With around 5,000 summertime residents, increased tourism, and a warming planet, it is becoming difficult to protect Antarctica from invasion.
For consumers of festive beverages, the news is bad: this holiday season, Guinness may not be on tap and glass for bottling wine is scarce. Climate disasters, like British Columbia’s floods, have further weakened already […]
Driving Teslas and planting trees are nice, but methane reduction, industrial efficiency, carbon removal, and a moderate carbon tax are the most efficient ways to fight climate change.
Society incorrectly blamed a "population bomb” for problems that had other causes. A wrong diagnosis produces ineffective solutions.
With sea levels rising, the Dutch are pondering floating cities — while also exporting their engineering know-how to turn a tidy profit.
