Solar energy 'revolution' brings green power closer
December 30, 2007 12:37 PM - John Vidal, environment editor, The Guardian

The holy grail of renewable energy came a step closer yesterday as thousands of mass-produced wafer-thin solar cells printed on aluminium film rolled off a production line in California, heralding what British scientists called "a revolution" in generating electricity.

Biofuels, the Biggest Scam Going
December 30, 2007 12:13 PM - , Organic Consumers Association

Where is agriculture headed? Can we feed a growing population and meet the demand for biofuels in the Industrialized North? Supporters of biofuel agriculture, (grain and chemical companies, Wall St. investors, politicians and most University researchers) avoid mentioning the cost of inputs, the fossil fuels, the environmental damage, the physical toll on animals and humans, and the growing problem of hunger that will accompany the switch from food to energy crop production. They want us to believe the switch to energy crops will be so easy and so practical.

Hypercar: The car that pays you to drive it
December 30, 2007 11:56 AM - , Triple Pundit

The car of the future is not only going to come standard with a hybrid powered engine; rather, the whole concept of a car from the ground up will be an entirely redeveloped mobility machine. A fine example is the Hypercar, a vehicle designed in reverse; featuring ultra light construction, hybrid-electric drive, low-drag design and efficient accessories to accomplish a 3 to 5-fold improvement on fuel efficiency. The major highlight? It can actually pay you to drive the car, imagine receiving a check at the end of each month just for driving a smart vehicle. The performance is poised to match current automobiles through comparable saftety, amenities and affordability.

Work on the car will begin in the New Year, and it is going to be built out of coconuts. Already a sports car, which has a top speed of 150mph, and goes from 0 – 62 mph in just four seconds, has been built from hemp, potatoes and rapeseed.

Risk of HIV, West Nile Virus, E Coli May be Reduced Through New Blood Screens

CHICAGO - The blood transfusion community should consider pathogen inactivation methods as an alternative way to assure the safety and availability of the nation's blood supply, a pathologist wrote in the December issue of the American Journal of Clinical Pathology (AJCP).

Fish Follow Prawns To Find Good Places To Eat

Professor Hart said: “It is a common experience for most of us to look at what other people are doing when we ourselves are not sure of what to do next. One of the benefits of being a social species is that we can tap into the expertise of our fellow humans to improve our own chances of success when circumstances are uncertain. Many would argue that a key element in the development of culture is the human ability to observe other’s behaviour and to copy it.

Prenatal X-rays don't raise kids' brain tumor risk
December 28, 2007 03:43 PM - Reuters

NEW YORK (Reuters Health) - Overall, children born to women who received an X-ray while pregnant are not more likely than other children to develop a brain tumor, Swedish researchers report based on a study they conducted. However, the study hints that abdominal X-rays during pregnancy may raise the risk of a specific type of brain tumor called primitive neuroectodermal tumors.

Most older adults have brain disease: study
December 28, 2007 03:34 PM - Megan Rauscher, Reuters

NEW YORK (Reuters Health) - Results of a brain autopsy study indicate that most older adults have significant brain pathology (disease), regardless of the presence or absence of outward signs of dementia. As part of the long-term Rush Memory and Aging Project, researchers evaluated the spectrum of abnormalities found in the brains of 141 older adults, with and without clinically evident dementia.

Solar Cells of the Future with Nano Flakes
December 28, 2007 12:04 PM - , Green Progress

A new material, nano flakes, may revolutionise the transformation of solar energy to electricity. If so, even ordinary households can benefit from solar electricity and save money in the future. If researcher Martin Aagesen’s future solar cells meet the expectations, both your economy and the environment will benefit from the research. Less than 1 per cent of the world’s electricity comes from the sun because it is difficult to transform solar energy to electricity. But Martin Aagesen’s discovery may be a huge step towards boosting the exploitation of solar energy.

New Finnish nuclear reactor start-up delayed
