Yes, The Internet Saves Energy
September 23, 2007 11:57 AM - Bruce Mulliken, Private Landowner Network
Recently, in this column, I said this, “I don’t think there’s been a study, and I can’t prove it, but I think the Internet is one of the greatest energy saving inventions ever created.”
Well, now there IS a study to back up my claim. The Consumer Electronics Association (CEA (tm)) thinks the Internet saves energy too; and it’s substantial.
The just-released study commissioned by the CEA and conducted by TIAX LLC of Cambridge, Massachusetts, shows that using electronics to telecommute saves the equivalent of 9 to 14 billion kilowatt-hours of electricity per year – the same amount of energy used by roughly 1 million US households every year.
Marijuana Component Opens the Door for Virus That Causes Kaposiâ€™s Sarcoma
September 21, 2007 06:04 PM -
PHILADELPHIA - The major active component of marijuana could enhance the ability of the virus that causes Kaposi's sarcoma to infect cells and multiply, according to a team of researchers at Harvard Medical School. According to the researchers, low doses of Δ-9 tetrahydrocannabinol (THC), equivalent to that in the bloodstream of an average marijuana smoker, could be enough to facilitate infection of skin cells and could even coax these cells into malignancy.
While most people are not at risk from Kaposi's sarcoma herpes virus (KSHV), researchers say those with lowered immune systems, such as AIDS patients or transplant recipients, are more susceptible to developing the sarcoma as a result of infection. Their findings, reported in the August 1 issue of Cancer Research, a journal of the American Association for Cancer Research, offer cautionary evidence that those with weakened immune systems should speak with their doctors before using marijuana medicinally or recreationally.
And cut! Cambridge scientists film new nanoscale battle scene
September 21, 2007 05:52 PM - University of Cambridge
University of Cambridge scientists have, for the first time, been able to film the interaction between a bacterial enzyme and a DNA strand from an attacking virus. The real-time footage shows how the enzyme attaches itself to the DNA of a virus, in order to cut the DNA before the virus has the chance to infect the bacterium.
NASA spacecraft finds possible Mars caves

WASHINGTON (Reuters) - An orbiting spacecraft has found evidence of what look like seven caves on the slopes of a Martian volcano, the space agency NASA said on Friday.
The Mars Odyssey spacecraft has sent back images of very dark, nearly circular features that appear to be openings to underground spaces.
"They are cooler than the surrounding surface in the day and warmer at night," said Glen Cushing of the U.S. Geological Survey's Astrogeology Team and Northern Arizona University.
Amid Big Promises, Plans Proceed For First GMO Foodcrop Release In India
September 21, 2007 12:58 PM - Paul Schaefer, ENN
India - India is about to serve as host to a newly developed GMO eggplant, the first ever GMO foodcrop for India. The plant has been genetically modified to contain a pesticide that promoters hope will make it resistant to the fruit and shoot borer. Researchers admit, many questions about the new GMO food remain unanswered. No human trials have been conducted in the US or India.
Environmental News 2.0: Online Communities fuel the Fight Against Global Warming
September 21, 2007 12:13 PM - Chris, Environmental Graffiti
Major online communities are becoming a huge force in making Global Warming a political priority. While there has been a lot of ink spilled about how online communities are changing the face of politics, the fact is that they really raise the profile of ordinary people’s concerns. Well, people are concerned about Global Warming, because as Carlos showed us in Climate Tipping Points Get Scarier … there are only about 10 years left to get a handle on the problem and the political leadership in the United States and around the world will be hugely influential in whether we fix the problem and see us united for a more just and sustainable world or we scramble to adapt to a hugely changing world through adaptation efforts like billion-dollar levees and conflict over increasingly scarce resources.
China Could Be Top Wind Market In 3 Years
September 21, 2007 11:55 AM - Emma Graham-Harrison, Reuters
BEIJING (Reuters) - China could become the world's top wind power market in three to five years but will grow faster if it reforms its subsidy system, executives of major wind turbine maker Vestas said on Friday.
Chief Executive Ditlev Engel, in China to open the second and third in a series of seven plants due to come on line by the first quarter of 2008, said he was convinced Vestas could compete with cheaper local rivals on quality.
But the company, the world's biggest wind turbine manufacturer, made its $80 million investment with an eye on both Chinese and export markets. Turbines not sold in China could be integrated into Vestas' global supply chain, he added.
The Hobbit: Not Human?
September 21, 2007 07:43 AM - Randolph E. Schmid, Associated Press
Scientists, wringing their hands over the identity of the famed "hobbit" fossil, have found a new clue in the wrist. Since the discovery of the bones in Indonesia in 2003, researchers have wrangled over whether the find was an ancient human ancestor or simply a modern human suffering from a genetic disorder.
Court Halts Introduction Of GMO Rice In The Philippines
September 20, 2007 05:12 PM - Imelda Abano, SciDevNet
PHILIPPINES - A Philippine court has temporarily halted an application to bring genetically modified (GM) rice to the country, pending a study of possible health and environmental effects.
A temporary restraining order was issued yesterday (18 September) after Greenpeace, together with other nongovernmental organisations, challenged the Philippine government's right to approve Bayer Crop Science's LL62, a herbicide-tolerant type of hybrid rice.
Vicious Velociraptor Dinosaur Was Feathered Fiend
September 20, 2007 02:41 PM - Will Dunham, reuters
WASHINGTON (Reuters) - The vicious little dinosaur Velociraptor was a feathered fiend, according to scientists who found evidence of quills on this well-known meat-eater's forearm.
In research published on Thursday, paleontologists said a forearm bone of Velociraptor found in Mongolia's desolate Gobi desert retained structures, or quill knobs, where a series of feathers were anchored to the bone with ligaments.
