POSTECH-Korea University joint research team develops a non-energy consuming radiative cooling material.

252 million years ago at the boundary between the Permian and Triassic epochs, Earth witnessed a mass extinction event that extinguished about three-quarters of all species on land and some 95 percent of all species in the ocean. Volcanic activity in today's Siberia has long been debated as a likely trigger of this event. Now, an international team of researchers provides for the first time a conclusive reconstruction of the key events that led to the mega-catastrophe.

Tropical Storm Nangka made landfall south of Haiphong, Vietnam and began to weaken. NASA's Aqua satellite revealed wind shear was affecting the storm as it continued to push inland.

Sediments from a lake in the Canadian High Arctic allow climate scientists to extend the record of Atlantic sea-surface temperature from about 100 to 2,900 years. It shows that the warmest interval over this period has been the past 10 years. A team led by Francois Lapointe and Raymond Bradley in the Climate System Research Center at UMass Amherst analyzed "perfectly preserved" annual layers of sediment that accumulated in the lake on Ellesmere Island, Nunavut Territory.

Norbert has been meandering around in the Eastern Pacific Ocean for several days as a tropical depression.

NASA's Terra satellite obtained visible imagery as Tropical Storm Delta made landfall in Louisiana and moved northeastward soaking the U.S. southeast and Mid-Atlantic states.
