An international team of biologists led by Indiana University's David M. Kehoe has identified both the enzyme and molecular mechanism critical for controlling a chameleon-like process that allows one of the world's most abundant ocean phytoplankton, once known as blue-green algae, to maximize light harvesting for photosynthesis.
Intense heat. Disappearing snowpack. We know that the environment of the American West is going to be hard-hit by climate change. Rising temperatures aren't good if you're, say, a delicate salmon egg or a mountain yellow-legged frog. But these changes also carry consequences for the region's economy.
A new study has revealed a rapid response between global temperature and ice volume/sea-level, which could lead to sea-levels rising by over one metre.
The role of climate change in the development and demise of classic Maya civilization, ranging from AD 300 to 1000, has been controversial for decades because of a lack of well-dated climate and archaeological evidence. But an international team of archaeologists and earth science researchers has compiled a precisely dated, high-resolution climate record of 2,000 years that shows how Maya political systems developed and disintegrated in response to climate change.
Stanford University engineer Shanhui Fan envisions a future where we don't just drive electric cars, we drive them on highways embedded with evenly spaced metal coils, generating electrical currents that charge the car wirelessly as it barrels down the road – car and coil never touch.
Climate scientists cannot attribute any single weather event — whether a drought, wildfire or extreme storm — to climate change. But extreme events, such as Hurricane Sandy, are glimpses of the types of occurrences the world could be more vulnerable to in the future. As the devastation left by Sandy continues to reverberate, decision-makers at every level are asking: How can we be better prepared?
Understanding Earth's paleo-hurricane record cannot be more timely and important in a light of Hurricane Sandy, which shocked the U.S. East Coast last week. Talks in this Wednesday afternoon session at the GSA Annual Meeting in Charlotte, North Carolina, integrate field, lab, and model analysis of past hurricanes and future scenarios, covering a wide range of temporal and spatial scales.
Global warming could cause frequent and severe failures of the Indian summer monsoon in the next two centuries, new research suggests.
Over the past decade, a global effort has been initiated to conserve and protect natural resources for future generations and to protect human health through environmental stewardship. However, the “Go Green” campaign is challenged on a daily basis by increasing land-use and transportation needs.
Researchers have discovered why plants and animals had a hard time recovering from the largest mass extinction in Earth's history 250 million years ago.
