Study: Refueling Planes Mid-Air Could Cut Fuel Use by 23%

A system for refueling passenger planes mid-air could slash the amount of kerosene needed for a long haul flight by nearly a quarter, researchers said Monday.

Kerosene reserves make up about a third of the weight on long distance passenger flights at take-off so reducing them and refueling mid-air could mean huge savings, said the Zurich University of Applied Sciences (ZHAW), which participated in the study.

Solar Impulse Departs Myanmar for China

Solar Impulse 2 took off from Myanmar's second biggest city of Mandalay early Monday and headed for China's Chongqing, the fifth flight of a landmark journey to circumnavigate the globe powered solely by the sun.

The single-seater aircraft's team spent more than a week waiting in Mandalay for weather conditions to improve in southwestern China for what will be one of the most challenging legs of the round-the-world attempt so far.

Antarctica both Alluring and Forbidding

Their beady little eyes, squarish torsos and adorable waddling make penguins one of the main attractions for tourists who come to Antarctica. But far from the surface waters where they swim with seals and whales, deep in the oceans and across thousands of miles of frozen continent is another side of Antarctica that is both forbidding and mysterious.

It's in those places that scientists study the rapid melting of icebergs and global warming, look for clues about humanity's past that could help us see the future and even find forms of life that survive and thrive in extremely harsh conditions.

The Salton Sea: A Time-bomb amid California Drought

At first sight the Salton Sea looks putrid, with dead fish scattered among patches of fetid water in a vast salty lake in the middle of the Californian desert.

In the fourth year of a historic drought in the western United States, some say the wetland is an environmental time bomb.

Ice Around Antarctica Shrank by almost 20 Percent

The ice floating around Antarctica has thinned by nearly 20 percent, according to research published Thursday, depleting the bulwark that prevents the permanent collapse of glaciers covering the southern continent.

The study, based on satellite measurements between 1994 and 2012 by the European Space Agency, sheds new light on how Antarctic ice responds to climate change.
