Washington, April 28 : New scientific evidence suggests that dinosaur bones from the Ojo Alamo Sandstone in the San Juan Basin, USA, date from after the mass extinction event, and that dinos may have survived in a remote area of what is now New Mexico and Colorado for up to half a million years, in a scenario resembling that of the fictional `Lost World'.

This controversial new research, is based on detailed chemical investigations of the dinosaur bones, and evidence for the age of the rocks in which they are found.

London, April 28 : In a new research, ecologists have determined that hurricanes can reduce the ability of forests to store carbon dioxide (CO2) and turn them into overall emitters of the toxic greenhouse gas.

According to a report in New Scientist, for the research, ecologist Jeffrey Chambers of Tulane University in New Orleans, Louisiana, and his colleagues, took the example of the forests in the US, which have been severely affected by the destruction wrecked by hurricanes over the past 150 years.

Washington, April 28 : In a new study, scientists have determined that solar energy has the potential to improve the living conditions of poor rural households in India as well as contribute to the country''s future energy security.

The study was done bv Professor Govindasamy Agoramoorthy from Tajen University, who is Tata-Sadguru Visiting Chair, and Dr. Minna Hsu from the National Sun Yat-sen University in Taiwan.

London, April 28 : Astronomers have spotted the most distant object yet confirmed in the universe, which is a self-destructing star that exploded 13.1 billion light years from Earth.

According to a report in New Scientist, it detonated just 640 million years after the big bang, around the end of the cosmic "dark ages", when the first stars and galaxies were lighting up space.

The object is a gamma-ray burst (GRB) - the brightest type of stellar explosion.

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, 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.
