May 22, 2013 A plant scientist at Mars Inc. has appealed to the world's biggest life sciences companies to help him — by sharing what they already know about 100 crops that could provide better nutrition in Africa. But can the kings of agricultural intellectual property get onboard with open source agricultural information for Africa?
May 22, 2013 Although scientists have known that a funguslike organism caused the potato blight that triggered the Great Famine in Ireland in the 1840s, they didn't know which strain was the culprit. But they do now, thanks to the genes in some 19th century potato samples.

May 21, 2013 Architects have come up with spectacular concepts for vertical farms that would grow crops in city skyscrapers. But many horticulturists think the future of vertical farming isn't in skyscrapers, but rather in large, indoor warehouses lit up magenta by superefficient LEDs.
May 21, 2013 When disaster strikes, our natural instinct is to take cover and seek shelter. But in severe weather, especially the type that breeds tornadoes like we saw in Oklahoma and parts of the Midwest this week, there are those who ride toward the storm.
May 20, 2013 Tornado strength is currently measured on what is called the Enhanced Fujita Scale, which gives the tornado a rating from 0 to 5 based on estimated wind speeds and the severity of the damage.
May 18, 2013 Afghanistan is believed to be home to world-class mineral deposits, valued at up to $3 trillion and offering hope for the country's economic future. But in the current environment of uncertainty, investors are nervous and it could be many years before Afghanistan strikes pay dirt.
May 18, 2013 Atmospheric scientist Ira Leifer installed special air sensors on a camper, then drove from Florida to California, measuring methane levels all along the way. More than 6,000 readings later, he found some noticeable spikes, especially around petrochemical plants and urban areas like Los Angeles.
