Will Detroit's cash crisis kill the electric car?
November 18, 2008 07:55 AM - Reuters

Call it an economic and environmental murder mystery in the making: Will a cash-strapped Detroit kill the electric car -- again? Stung by an association with gas-guzzling SUVs and pushed to the brink of failure by plunging sales, U.S. automakers have been touting efforts to roll out more fuel-efficient small cars, gas-saving technology and gas-free electric vehicles.

New bacteria discovered in raw milk
November 17, 2008 08:27 AM - Society for General Microbiology

Raw milk is illegal in many countries as it can be contaminated with potentially harmful microbes. Contamination can also spoil the milk, making it taste bitter and turn thick and sticky. Now scientists have discovered new species of bacteria that can grow at low temperatures, spoiling raw milk even when it is refrigerated. According to research published in the November issue of the International Journal of Systematic and Evolutionary Microbiology, the microbial population of raw milk is much more complex than previously thought.

Physics can help fuel economic growth
November 13, 2008 09:16 AM - , SciDevNet

Developing countries need a broad-based capacity in physics to achieve sustainable economic growth, says Reza Mansouri in aNature supplement published to coincide with the twenty-fifth anniversary of TWAS, the academy of sciences in the developing world.

Recycled Glass Countertops Take Home CleanTech Award
November 13, 2008 09:06 AM - , Triple Pundit

As GreenBiz reported on Tuesday, the 2008 CleanTech Open concluded earlier this week, showcasing some of the most exciting new innovations in the world of sustainability. Among the winners walking away with a prize package worth $100,000 in cash and business resources was BottleStone, a Los Altos Hills company that makes ceramic stone countertops out of recycled glass.

Hybrid tugboat may give local ports a green push
November 13, 2008 08:40 AM - LA Times

For all of its 21st-century advancements, the shipping industry drags a lot of old technology around. Giant vessels are so sophisticated these days that they require only a handful of crew members. But the ships still burn a thick, dirty sludge called bunker fuel while at sea and slurp diesel to keep the lights and air conditioning running while in port.

A global race for the plug-in hybrid battery hits the back stretch

The ingredients for a multibillion-dollar global technology race sit on a table here in this Milwaukee suburb. They make the process seem pretty simple: Two strips of specially coated foil and a thin, plastic-like material called a separator are carefully wrapped together in a layered spiral that technicians here call the "jelly roll."

Engineers have constructed a solar array smaller than a dime out of 20 solar cells
November 7, 2008 08:37 AM - American Institute of Physics

Engineers have constructed a solar array smaller than a dime out f 20 solar cells, each cell tinier than a quarter of this lowercase "o." The mini photoelectric device only generates seven volts of electricity, but that could be enough to power microsensors like those military planners imagine will provide the soldier of the future with first-person-shooter-like battlefield intelligence. That's why the Army is a major sponsor of the project, which is described in the Journal of Renewable and Sustainable Energy.

UK Scientists Compare Official G8 Proposals To Combat Climate Change With Real Carbon Cycle Data
November 7, 2008 08:32 AM - , Global Warming is Real

A few UK scientists have done a smart thing; they’ve combined the proposals of G8 policymakers for combating climate change with actual data on the status of play in the carbon cycle. The resulting study (pdf) is interesting not only because of this highly useful approach but also because it focuses on atmospheric carbon dioxide and its impact on the environment in the far future.

Ecologists use oceanographic data to predict future climate change
November 7, 2008 08:18 AM - Ecological Society of America

Earth scientists are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. In a November special issue of the journal Ecology, a group of scientists report that if current patterns of change in the Arctic and North Atlantic Oceans continue, alterations of ocean circulation could occur on a global scale, with potentially dramatic implications for the world's climate and biosphere.

Robots show that brain activity is linked to time as well as space
November 7, 2008 08:14 AM - Public Library of Science

Humanoid robots have been used to show that that functional hierarchy in the brain is linked to time as well as space. Researchers from RIKEN Brain Science Institute, Japan, have created a new type of neural network model which adds to the previous literature that suggests neural activity is linked solely to spatial hierarchy within the animal brain. Details are published November 7 in the open-access journal PLoS Computational Biology.
