Tanzania is one developing country that could actually benefit from climate change by increasing exports of corn to the U.S. and other nations, according to a study by researchers at Stanford University, the World Bank and Purdue University. The study, published in the Review of Development Economics, shows the African country better known for safaris and Mt. Kilimanjaro has the potential to substantially increase its maize exports and take advantage of higher commodity prices with a...

X-ray Imaging To Observe Running Batteries In Action

Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries — a pricey technology that accounts for more than half of the vehicle's total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more energy at a much lower cost. But lithium-sulfur technology has a major drawback: After a few dozen cycles of charging and discharging, the battery stops working. "The cycle life of...

Soot Particles Measured In Flight

"For the first time we can actually see the structure of individual aerosol particles floating in air, their 'native habitat'," said DESY scientist Henry Chapman from the Center for Free-Electron Laser Science (CFEL) in Hamburg. "This will have important implications for various fields from climate modelling to human health." CFEL is a joint venture of Deutsches Elektronen-Synchrotron DESY, the German Max Planck Society and the University of Hamburg. Aerosol particles like soot play...

Aerosol Structures Exposed By X-ray vision

Laser probes microscopic components of air pollution Researchers at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard. The discovery reveals the particles' surprisingly complex nanostructures and could ultimately aid the understanding of atmospheric processes important to climate change, as well as the design of cleaner combustion...

New Interest Sparked In The Century-old Edison Battery

Stanford University scientists have breathed new life into the nickel-iron battery, a rechargeable technology developed by Thomas Edison more than a century ago. Designed in the early 1900s to power electric vehicles, the Edison battery largely went out of favor in the mid-1970s. Today only a handful of companies manufacture nickel-iron batteries, primarily to store surplus electricity from solar panels and wind turbines. "The Edison battery is very durable, but it has a number of...
