alf the elephants from West and Central African savannahs have vanished in the past 40 years, scientists report in PLoS One.

EADS is looking to release an entirely electricity powered plane by the year 2035. The plane, which has been dubbed the VoltAir, was shown off at the Paris Air Show, which took place last week. The Paris Air Show is one of the largest aviation shows in the world.

Some areas of the southern United States are suffering from the longest dry spell since 1887 and a new Baylor University study shows that could prove problematic for aquatic organisms.

Greenland's ice sheet melted the most it has in over a half century last year, US government scientists said Tuesday in one of a series of "unmistakable" signs of climate change.

The obscure technology used in heated automobile seats, gadgets that charge iPhones from the heat of a campfire, and other devices is undergoing a renaissance and could well emerge as a new "green" substitute for traditional sources of energy and play other key roles in addressing some of society's most pressing sustainability issues. That's the conclusion of an article on the technology - termed thermoelectrics - in the current issue of Chemical & Engineering News (C&EN) the American Chemical Society's weekly newsmagazine.

A recently completed aerial survey of northern Botswana by Elephants Without Borders (EWB), through the support of Botswana's Dept. of Wildlife & National Parks, indicates that wildebeest, giraffes, kudu, lechwe, ostriches, roan and tsessebe antelope and warthog species are significantly challenged. Populations of these species appear to have dropped significantly over the past 15 years, specifically in Ngamiland, which encompasses the Okavango delta.

The island nation of Singapore is aggressively promoting a solution to the water scarcity that vexes countries worldwide: recycling toilet water to drink.

The health of the world's oceans is declining much faster than originally thought - under siege from pollution, overfishing and other man-made problems all at once - scientists say in a new report.

An international research team including University of Pennsylvania scientists has shown that the rate of sea-level rise along the U.S. Atlantic coast is greater now than at any time in the past 2,000 years and that there is a consistent link between changes in global mean surface temperature and sea level.

Pollution and global warming are pushing the world's oceans to the brink of a mass extinction of marine life unseen for tens of millions of years, a consortium of scientists warned Monday.

During the last space shuttle flight, astronauts will test a new method for recycling 'used' water. Water is essential for life, and having access to water beyond Earth will be a major obstacle for future space explorers.

On the heels of another halting round of talks on climate change, UN scientists this week will review quick-fix options for beating back the threat of global warming that rely on technology rather than political wrangling.

Climate change disasters, such as the melting of the Greenland ice sheet, dieback of the Amazon rainforest or collapse of the Atlantic overturning circulation, could be predicted according to University of Exeter research.

A device the size of a deck of playing cards that can track temperature, humidity, light and barometric pressure is moving from the shipping world to the realm of research to help develop a better understanding of how the climate is changing.

The time may finally be right to sell Americans on eco-driving, according to a group of transportation experts from four University of California campuses as well as representatives from industry and government who attended an all-day conference on May 18.

As a kid growing up near the space program in Huntsville, Ala., reading as much science fiction as he could get his hands on, Kasting had space exploration on his mind all the time. It influenced who he is today as well as the research he's most interested in conducting. By studying early Earth's atmosphere and the origins of oxygen in it, Kasting has become one of the foremost experts on planetary habitable zones. In his book, "How to Find a Habitable Planet," Kasting explains how his research with NASA may be able to detect worlds outside of our solar system that are suitable for sustaining life.

As America struggles down the road toward a coherent energy policy that focuses on a higher degree of self-reliance, policymakers face numerous issues and realities. These include: the finite supply and environmental impact of fossil fuels, the feasibility and costs to implement a widespread switch to renewable energy sources, and the variables that lead to consumers' preferences for particular types of power generation.

Not all research papers receive their own hashtag on Twitter. But #arseniclife (as it was dubbed in tweets) was no ordinary paper.

Any architect recognizes the Office of Metropolitan Architecture (OMA), lead by star architect Rem Koolhaas, as one of the most important and thought-provoking architectural firms in the world. The counterpart to OMA's architectural practice is AMO, a design and research studio that specifically focuses on areas beyond the traditional boundaries of architecture, such as media, politics, sociology, technology, fashion or graphic design. Remarkably, it seems AMO is getting more and more active in developing complex-scale, mass-medium data graphics. In February of this year, they presented the "Energy Report" for the WWF, a comprehensive study claiming that the world can be 100 percent reliant on renewable energy by 2050.

The United Nations food agency on Monday called for greater use of environmentally sustainable techniques by poor farmers in order to increase crop intensity to feed the world's growing population.
