How hybrid electric and fuel aircraft could green air travel

With air traffic set to increase 5% every year until 2030, scientists are looking at how to make aeroplanes more sustainable. But with current batteries making electric aircraft far too heavy, hybrid fuel and electric models could point the way forward for greener air travel—and could become airborne within 15 years.

Cloud shapes and formations impact global warming – but we still don't understand them

Above the Atlantic Ocean, puffy white clouds scud across the sky buffeted by invisible trade winds. They are not 'particularly big, impressive or extended," says Dr. Sandrine Bony, a climatologist and research director at the French National Centre for Scientific Research. "But they are the most ubiquitous clouds on Earth."

Researchers develop DNA approach to forecast ecosystem changes

When wolves returned to Yellowstone in 1995, no one imagined the predators would literally change the course of rivers in the national park through cascading effects on other animals and plants. Now, a Stanford University-developed approach holds the promise of forecasting such ecosystem changes as certain species become more prevalent or vanish altogether.
