New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…

NASA and NOAA satellites were watching the low pressure System 98L in the central Atlantic yesterday when it was 1450 miles east of the Leeward Islands.Yesterday, Sept. 20, 2011 at 4:11 p.m. NASA's Aqua satellite flew over System 98L before it became a tropical storm. An infrared image from the Atmospheric Infrared Sounder instrument onboard showed System 98L's strongest thunderstorms and coldest cloud tops (colder than -63F/-52C) were banded north and south of the center of circulation. Those bands of thunderstorms were a sign that the low pressure area was organizing and strengthening….
