Though it may look haphazard, the network of intertwining plant roots snaking through the soil actually represents a deliberate process. Root growth is guided by chemical snapshots taken by young roots, allowing them to detect obstructions and coordinate the paths they take, new research led by Florida Institute of Technology finds.

Roots compete for and share resources with neighboring roots, as well as with billions of microbes. Until now, however, little has been known about how plants coordinate construction of these complex subterranean assemblies.

The Trump administration has announced that a federal goal to slash the cost of utility-scale solar energy to 6 cents per kilowatt-hour by 2020 has been met early. The goal, set by the Obama administration in 2011 and known as the SunShot Initiative, represents a 75 percent reduction in the cost of U.S. solar in just six years. It makes solar energy-cost competitive with electricity generated by fossil fuels.

Climate change will force many amphibians, mammals and birds to move to cooler areas outside their normal ranges, provided they can find space and a clear trajectory among our urban developments and growing cities.

A new Cornell University study shows that deforestation and subsequent use of lands for agriculture or pasture, especially in tropical regions, contribute more to climate change than previously thought.

NASA’s Aqua satellite observed fragmented feeder bands of strong thunderstorms spiraling into the low-level center of Tropical Cyclone Doksuri.  

On Sept. 13 at 2:10 a.m. EDT (0610 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA’s Aqua satellite captured a visible-light image of the storm as it moved west in the South China Sea. Fragmented bands of thunderstorms spiraled into the center from the western and southern sides of the storm.
