Weird dinosaur was "cow of the Mesozoic"
November 16, 2007 08:40 AM - Reuters

WASHINGTON (Reuters) - A strange-looking dinosaur with rows of tiny teeth crammed into the very front of its jaws and fragile air-filled bones may have been the "cow of the Mesozoic," and far more common than better-known dinosaurs, scientists said on Thursday.

Its shovel-shaped jaws and tightly packed teeth -- up to 10 rows of teeth -- allowed Nigersaurus taqueti to vacuum through ferns and other ground cover, a team led by Paul Sereno at the University of Chicago reported.

The normally sedate Comet Holmes made a bright splash in the sky about two weeks ago, unexpectedly becoming a million times brighter than normal overnight and causing a stir among astronomers.

The comet and its expanding ball of dust have become the biggest object in the solar system, with a diameter appearing even bigger than the sun, according to astronomers at the University of Hawaii Institute for Astronomy.

In response to the need for localized efforts to protect and recover the surviving populations of the threatened staghorn coral, Diego Lirman, Ph.D., and James Herlan, researchers from the University of Miami’s Rosenstiel School of Marine and Atmospheric Science (RSMAS) have established an underwater nursery dedicated to the propagation of staghorn corals.

Yellowstone Viruses 'Jump' Between Hot Pools
November 15, 2007 09:36 AM - INL

A population study of microbes in Yellowstone National Park hot pools suggests viruses might be buoyed by steam to distant pools. The result, to be published online next week in the Proceedings of the National Academy of Sciences, could help to answer some fundamental questions about how microbes, and the viruses that infect them, impact their environment.

Small Planets Forming in the Pleiades: Astronomers
November 15, 2007 09:06 AM - Reuters

WASHINGTON (Reuters) - Small, rocky planets that could resemble the Earth or Mars may be forming around a star in the Pleiades star cluster, astronomers reported on Wednesday.

One of the stars in the cluster, also known as the Seven Sisters, is surrounded by an extraordinary number of hot dust particles that could be the "building blocks of planets" said Inseok Song, a staff scientist at NASA's Spitzer Science Center at the California Institute of Technology.

German Carmakers Lag France, Italy in CO2 Cuts: Group
November 15, 2007 09:03 AM - Reuters

STRASBOURG, France (Reuters) - Average carbon dioxide (CO2) emissions from new cars made by German manufacturers rose in 2006, while French and Italian producers cut pollution from their vehicles, data showed on Thursday.

Brussels-based environmental group Transport & Environment (T&E) said average emissions from new German vehicles jumped 0.6 percent last year because Germany was producing heavier cars, while French and Italian manufacturers cut emissions from their new cars by 1.6 percent on average.

Crowd Farm
November 15, 2007 08:44 AM - Triple Pundit

Crowd Farm, developed by two MIT architecture grad students, is a concept that harvests the energy that is transmitted through our feet. It works like this: Beneath highly crowded subway platforms there would be a sub-flooring system made up of blocks that depress slightly due to the force of human footsteps above. These blocks rub together under the pressure generating power the same way as a dynamo, a device that converts energy from motion into an electric current.
