Past global warming similar to today's: Size, duration were like modern climate shift, but in two pulses
The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to ...
Buckyballs enhance carbon capture: Environmentally friendly material targets flue gases, wells
(Phys.org)—Rice University scientists have discovered an environmentally friendly carbon-capture method that could be equally adept at drawing carbon dioxide emissions from industrial flue gases and natural ...
Bacteria become 'genomic tape recorders'
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for ap ...
Researchers discover a way to tease oxygen molecules from carbon dioxide
A nanosized hydrogen generator
(Phys.org) —Researchers at the US Department of Energy's (DOE) Argonne National Laboratory have created a small scale "hydrogen generator" that uses light and a two-dimensional graphene platform to boost ...
Plant engineered for more efficient photosynthesis
(Phys.org) —A genetically engineered tobacco plant, developed with two genes from blue-green algae (cyanobacteria), holds promise for improving the yields of many food crops.
Ride-sharing could cut cabs' road time by 30 percent
Cellphone apps that find users car rides in real time are exploding in popularity: The car-service company Uber was recently valued at $18 billion, and even as it faces legal wrangles, a number of companies ...
Scientists develop a water splitter that runs on an ordinary AAA battery
In 2015, American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers. Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made from ...

Satellite data shows livestock emitted more methane than oil and gas industry in 2004
Discovery provides insights on how plants respond to elevated CO2 levels
Biologists at UC San Diego have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere.
Hot tropical oceans during Pliocene greenhouse warming
The impact of the greenhouse gas CO2 on the Earth's temperature is well established by climate models and temperature records over the past 100 years, as well as coupled records of carbon dioxide concentration ...
Tropical trees may not be the carbon sink planet scientists have been hoping for
Most carbon-dense ecosystem in Amazonia mapped for first time
The highest concentration of carbon in parts of Amazonia is not stored in trees, but below the ground as peat, according to new University of Leeds research.
