‘ZeroCAL’ cement production process takes CO2 out of the equation

Researchers at UCLA have successfully devised a way to produce cement with 98% less CO2 emissions than traditional methods. The team achieved this by decomposing limestone to access calcium oxide (aka lime) without releasing carbon dioxide.

Long-life ‘air motors’ show promise in marine testing

While battery-electric ferry boats may be more eco-friendly and require less maintenance than their diesel-burning counterparts, they're still not perfect. That's why scientists are now looking into powering small ferries using nothing but compressed air.

Storm clouds generate strange gamma radiation

Thor and the Hulk may be more closely related than we thought. Thunderstorms are known to produce gamma rays in the atmosphere, but a new study has found that not only do they happen way more often than we realized, but they’re much weirder.
