TOKYO- Toyota Motor Corp said on Friday its improved FCHV zero-emission fuel-cell car completed a road test from Osaka to Tokyo, covering 560 km (350 miles), on a single tank of hydrogen.  The latest version of the FCHV features a high-pressure tank of 70Mpa that can store double the amount of hydrogen as its previous fuel tank, increasing its cruising range. Two cars were tested and both completed the trip, the automaker said.

Human parasite genome reveals long past

CHICAGO (Reuters) - An icky parasite that is a major source of tummy trouble for young children and nature lovers appears to have been infecting mammals for a very long time, U.S. researchers said on Thursday.

Giardia lamblia is one of the most common human parasites in the United States, causing more than 20,000 intestinal infections each year.

A complete genetic sequence of this parasite now suggests it had ancestors reaching back more than a billion years.

"We think it is deep in the evolutionary tree," said Hilary Morrison, of the Marine Biological Laboratory in Woods Hole, Massachusetts, whose study appears in the journal Science.

The Benefits of a Low-Carbon Future
September 27, 2007 08:45 AM - Janet L. Swain, Worldwatch Institute

Yesterday, we weighed in on the need for stronger leadership on climate change from the United States and China in light of this week’s landmark meetings at the UN and White House. Today, we’ll provide a run-down of the benefits of addressing climate change—and what we stand to lose if we don’t.

The Stern Report, compiled for the UK government and released in late 2006, estimates that the costs of climate change under a "business-as-usual" scenario could equal the loss of 5 to 20 percent of gross world product each year. In contrast, the report puts the costs of efforts to avoid the worst impacts at only about 1 percent of gross world product. Since then, the International Energy Agency and the Intergovernmental Panel on Climate Change have issued similar conclusions.

Ice-Based Airconditioning Takes Off In California

SAN FRANCISCO - A company that makes an ice-based air-conditioning system is teaming up with a major public utility, PG & E, in California in a $10-million dollar project. The ice-based air conditioner uses cheaper nighttime electricity to make ice and then uses that ice for daytime cooling needs. The units cooling looks almost identical to a standard AC unit. The systems lowers peak daytime demand significantly, shifting the energy load up to 95%. The California Public Utilities Commission says permanent load shifting technologies deliver a number of benefits to both utilities and energy consumers, including added protection against shortages during heat waves and reduced reliance on the construction of new generation plants.

Email Overtakes Telephony

NEW YORK - New research shows that e-mail has overtaken telephony as a communication tool in the workplace. Other electronic communication tools are also reaching high adoption levels.

"In today's corporate environment there is a myriad of communications tools available including desktop telephony, mobile telephony and e-mail, among others. However, our research indicates that end-users prefer to communicate using electronic media rather than voice services such as telephony," said Rob Lopez, managing director, Solutions at Dimension Data whose firm conducted the survey.

WASHINGTON — Allegations of mismanagement, industry influence, and suppression of whistleblowers at the National Institute of Environmental Health Sciences and the National Toxicology Program (NTP) are being investigated by Congress, and the director has temporarily stepped down. Today, OMB Watch released a report that further documents industry's attempt to restrict access to health and safety information produced by NTP.

Rare albino ratfish has eerie, silvery sheen
September 25, 2007 08:14 AM - University of Washington

A ghostly, mutant ratfish caught off Whidbey Island in Washington state is the only completely albino fish ever seen by both the curator of the University of Washington's 7.2 million-specimen fish collection and a fish and wildlife biologist with more than 20 years of sampling fish in Puget Sound. Powerful jaws and grinding teeth able to crack the shells of crabs and clams require caution by researchers and fishermen who handle them. Ratfish don't bite divers or swimmers in the water, Reum says, but they get snappish when brought on board.

Arctic science outpost a refuge from the world

NORTHEASTERN STATION, Russia (Reuters) - When Soviet leader Leonid Brezhnev died and the Communist propaganda machine organized a mass outpouring of grief, Sergei Zimov hardly noticed.Back in November 1982, the young scientist was roaming around local shops and warehouses looking for the nails he needed to finish building a scientific research station high above the Arctic Circle that he had founded two years earlier.
