More water pressure means shorter showers, UK study finds
University students used less water during their showers when they had more water pressure — and they could see a clock.
Flowers grown floating on polluted waterways can help clean up nutrient runoff and turn a profit
Flowers grown on inexpensive floating platforms can help clean polluted waterways and even make a profit from cut flower sales.
How marine permaculture could revolutionize ocean farming
Marine permaculture could contribute to ecosystem restoration and pollution reduction, as well as empower local communities.
Doomerism’s “tipping point” and why existentialism isn’t the solution to the climate crisis
We can't afford to lose optimism over averting the worst consequences of this crisis; without it, we're trapped in a response of inaction.
A new way to swiftly eliminate micropollutants from water
Scientists at MIT are using zwitterionic hydrogels to sustainably capture both organic and inorganic micropollutants from water.
Bioengineers design a new plant to purify air faster than nature
Neoplants has bioengineered a pothos plant that removes 30 times more pollutants from the air than a regular houseplant.
How much CO2 can the world emit while keeping warming below 1.5°C and 2°C?
Researchers estimate how much more CO2 we can emit to keep temperatures below 1.5°C and 2°C to combat climate change.
Light may cause water to evaporate (even without heat)
MIT researchers propose a new phenomenon that causes to water evaporate without heat. They call it the “photomolecular effect.”
Green shipping picks up speed
The shipping industry aims to get to net-zero emissions by 2050. Can novel fuels, wind power and coordination on a global scale get it there?
MIT design would harness 40 percent of the sun’s heat to produce clean hydrogen fuel
Engineers hope to produce totally green, carbon-free hydrogen fuel with a new, train-like system of reactors driven by the sun.
