Variable light illuminates the distribution of picophytoplankton

Tiny photosynthetic plankton less than a millionth of a millimeter in diameter numerically dominate marine phytoplankton. Their photosynthesis uses light to drive carbon dioxide uptake, fueling the marine food web over vast areas of the oceans. A new study published in this week's PLoS ONE by postdoctoral researcher Dr. Christophe Six and a team of scientists from MountAllison University, Sackville, New Brunswick, Canada, illuminates how the environment regulates the distributions of these ecologically important species.

2. Animal studies in the land of the midnight sun illuminate biological clocks
   02-08-2007 · EurekAlert!
   How do animals living in the continuous light of the Arctic summer know when to sleep and when to be active? Do they maintain a 24-hour cycle of rest and activity, or does living in continuous light alter their circadian rhythm?Answering these questions may improve our understanding of biological clocks -- the internal, genetically programmed cycle of rest and activity that affects the behavior, metabolism and physiology of all animals, including humans.

5. ESRF helps reveal the origin of the Solar System
   12-15-2006 · EurekAlert!
   Particles returned to Earth last January by the Stardust spacecraft from comet Wild two are yielding precious information about the origin of the solar system, thanks to the X-rays produced at several of the world's synchrotron facilities, including the ESRF. Although the particles are tiny, the beams available at synchrotrons can be even smaller, enabling researchers to illuminate the cometary material and determine the distribution of elements within the particles without damaging them.

8. Massive dinosaur discovered in Antarctica sheds light on life, distribution of sauropodomorphs
   12-10-2007 · EurekAlert!
   A new genus and species of dinosaur from the Jurassic has been discovered in Antarctica. The massive plant-eating primitive sauropodomorph is called Glacialisaurus hammeri and lived about 190 million years ago. The fossils were painstakingly removed from the ice and rock using jackhammers, rock saws and chisels under extremely difficult conditions over two field seasons. The long-necked herbivorous sauropods were the largest animals to walk the earth. They include Diplodocus and Apatosaurus.

9. Television just got brighter: UCLA engineers are obsessed with the next generation of LEDs
   05-17-2007 · EurekAlert!
   Making LEDs, or light-emitting diodes -- which illuminate today's plasma TV screens and cell phones more efficient -- cheaper and higher quality is the obsession that occupies the daily thoughts of UCLA Engineering professor Yang Yang and researcher Jinsong Huang. They have recently achieved the highest lumens per watt ever recorded for a red phosphorescent LED using a new combination of plastic, or polymer, infused liquid -- and they did it at half the current cost.
