Washington, April 27 : A new research has highlighted the importance of stopping spam as it produces greenhouse gases that harms the planet.

According to a report in The Sydney Morning Herald, the research shows all those unsolicited messages, 62 trillion of them last year, generate greenhouse gases equivalent to driving a car around the planet 1.6 million times.

More than 80 per cent of the world's email traffic is now deemed spam and - between the energy devoted to sending, storing and sorting phoney messages - 33 billion kilowatt-hours of power is wasted.

Washington, Apr 27 : Former `O. C.' star Mischa Barton is all set to return to TV. She would be seen in a new fashion-based show alongside Ashton Kutcher.

The 23-year-old star had bid adieu to the teen drama in 2006 to pursue a movie career.

Washington, April 27 : A new study, conducted by Canadian researchers, has found that the combination therapy of vitamin E, selenium and soy does not prevent the progression from high-grade prostatic intraepithelial neoplasia (HGPIN) to prostate cancer.

For the study, researchers divided 303 men, with an average age of 62, into two randomized groups.

All participants had HGPIN, a precursor to invasive prostate cancer, as confirmed by a central pathology review in at least one of two biopsies within 18 months prior to randomization.

Washington, April 27 : Researchers in the US have made a new electrical device that could improve fuel cell technology by turning carbon dioxide (CO2) into methane, a potential biofuel.

According to a report in ABC News, the technique won't combat global warming directly, since both CO2 and methane are potent greenhouse gases, but it could help store alternative energies such as wind and solar more efficiently.
