Steven Chu on the futuristic batteries and "little weird" bacteria that will pave our way to energy independence
How can we feed a growing population while at the same time coping with the impacts of climate change on agriculture?
New technology converts all kinds of plant waste into usable fuel--and is part of a growing array of technologies aimed at island energy independence
A demonstration project in California may prove that steam created with the sun's heat can help get more oil out of the ground
The relatively pleasant global climate of the past 10,000 years is largely thanks to higher levels of atmospheric carbon dioxide
By pairing biology and photovoltaics, a new "electrofuel" system could build alternative fuels
Fossil rain suggests the atmosphere 2.7 billion years ago boasted a hydrocarbon haze
Can small, LEGO-like reactors help create better prospects for the nuclear industry?
Scientists have debated whether climate change or human activity wiped out the world's megafauna. In Australia new evidence points to hunting--and only hunting
The U.K. is grappling with how to get rid of weapons-grade plutonium and may employ a novel reactor design to consume it
The U.S. government aims to improve energy production from renewables to oil, but what does that mean in practice?
The U.S. has reactors of the same designs that melted down at Fukushima Daiichi, but regulators hope changes could prevent a repeat of Japan's nuclear crisis
The Fukushima evacuation zone raises the issue of what would happen during an evacuation in heavily populated U.S. metropolises during a nuclear meltdown
The third annual ARPA-E summit showcases potentially transformative energy technologies
Material changes enable a new battery to store more electricity--and could boost the driving range of electric vehicles
Michael E. Mann set out looking for a big scientific problem and wound up at the center of a political storm over climate change. Now he tells his side of the story
A genetic analysis reveals the ancient, complex--and symbiotic--roots of photosynthesis in plants
Based on some fundamental characteristics of cellular proteins, a team of scientists speculates that the last common ancestor of life on Earth got its start in the planet's natural hot tubs...
Curbing methane and soot may be a fast, if incomplete, way to slow global warming
Humans may have been causing climate change for much longer than we've been burning fossil fuels. In fact, the agrarian revolution may have started human-induced climate changes long before the industrial revolution began to sully the skies...
