Several hundred images taken with NASA's Hubble Space Telescope have been woven together into a rich tapestry of at least 50,000 galaxies. The Hubble view is yielding new clues about the universe's youth, from its "pre-teen" years to young adulthood.

The snowstorm of galaxies in the Hubble panorama does not appear evenly spread out. Some galaxies seem to be grouped together. Others are scattered through space. This uneven distribution of galaxies traces the concentration of dark matter, an invisible web-like structure stretching throughout space.

Solar energy has the power to reduce greenhouse gases and provide increased energy efficiency, says a scientist at the U.S. Department of Energy's Argonne National Laboratory, in a report (view it online) published in the March issue of Physics Today.

 Last month, The Intergovernmental Panel on Climate Change (IPCC) of the United Nations released a report confirming global warming is upon us and attributing the growing threat to the man-made burning of fossil fuels.

A Georgia Tech researcher has discovered that for tasks involving spatial processing, preparing for the task and performing it are not two separate brain processes, but one – at least when there are a small number of actions to choose from.

Drinking a specially-made cocoa beverage daily may have the potential to reverse impairments in the functioning of blood vessels, according to a first-of-its-kind study published in the Journal of Cardiovascular Pharmacology. The cocoa used in the study was rich in flavanols, naturally-occurring compounds abundant in freshly harvested cocoa prior to their destruction during the typical processing and manufacture of cocoa and chocolate products.

These results suggest this flavanol-rich cocoa could have important implications for cardiovascular health since reduced endothelial function is recognized as an early stage in blood vessel diseases such as atherosclerosis.

Scientists have identified a molecular switch that causes the differentiation of neurons in the cerebellum, a part of the brain that helps to regulate motor functions.

A study published this week in the scientific journal PNAS provides new information on the origin of different cells in the cerebellum, an important component of the central nervous system found in all vertebrates, including humans, and the part of the brain that controls movement. The study was completed by researchers from the Institute for Research in Biomedicine (IRB Barcelona), the Department of Cell Biology of the University of Barcelona (UB), the IMIM-Hospital del Mar, Pompeu Fabra University (UPF) and Vanderbilt University (Nashville, Tennessee, USA). The main authors of the study are Dr.

Leafy greens and beans aren't the only foods that pack a punch of folate, the vitamin essential for a healthy start to pregnancy.

Researchers now have used genetic engineering--manipulating an organism's genes--to make tomatoes with a full day's worth of the nutrient in a single serving. The scientists published their results in this week's online edition of the journal PNAS, Proceedings of the National Academy of Sciences.
