Reintroducing Megafauna To North AmericaDozens of megafauna (large animals over 100 pounds) such as giant tortoises, horses, elephants, and cheetah went extinct in North America13,000 years ago during the end of the Pleistocene. As is the case today in Africa and Asia, these megafauna likely played keystone ecological roles via predation, herbivory, and other processes. What are the consequences of losing such important components of America's natural heritage?

Stellar Birth Control In The Early UniverseAn international team of astronomers based at Yale and Leiden University in The Netherlands found that "old stars" dominated many large galaxies in the early universe, raising the new question of why these galaxies progressed into "adulthood" so early in the life of the universe.
Every year only a handful of new stars are born out of the gas that fills the space between the stars in galaxies like the Milky Way. To account for the large........Go to the Astronomy-blog (Added on 10/1/2006 7:10:31 PM)

Glue Made From Ethanol More Than The Fuel ItselfMixing up a batch of ethanol from alfalfa or switchgrass isn't nearly as efficient as creating it from corn, but that doesn't mean growing grass crops for fuel won't pay, says Paul Weimer.
Rather than dwelling on finding ways to squeeze extra ethanol out of biomass from crops such as switchgrass, Weimer is concentrating his research on the leftovers. He thinks that the large heap of fermentation residue from the ethanol-making process -........Go to the New-technology-blog (Added on 9/27/2006 8:57:51 PM)

Nanoparticles To Aid Brain ImagingIf you want to see precisely what the 10 billion neurons in a person's brain are doing, a good way to start is to track calcium as it flows into neurons when they fire.
To that end, Alan Jasanoff at the McGovern Institute for Brain Research at MIT has developed a new nano-sized calcium-sensing contrast agent that is detectable by magnetic resonance imaging (MRI) scanners, machines that can be used for detailed noninvasive brain imaging.

Watch How Planets FormWith the VISIR instrument on ESO's Very Large Telescope, astronomers have mapped the disc around a star more massive than the Sun. The very extended and flared disc most likely contains enough gas and dust to spawn planets. It appears as a precursor of debris discs such as the one around Vega-like stars and thus provides the rare opportunity to witness the conditions prevailing prior to or during planet formation.
