Posted On: May 17 2008 Astronomers have been baffled by the discovery of a star that lies 20,000 light-years away, spinning at a rate of 465 revolutions per second - the fifth fastest-spinning pulsar known in our Galaxy. The super fast pulsar, called J1903+0327, was detected with the Arecibo radio telescope in Puerto Rico. Astronomers believe such super-fast pulsars started life as the more common, sedate pulsars that s ...Read Full News Biodiversity on Earth is declining Posted On: May 17 2008 The WWF, also known as the World Wildlife Fund, says more than a quarter of the Earth's wildlife has been lost during the last 35 years.The organization's Living Planet Index -- produced for the WWF by the Zoological Society of London -- shows populations of marine species, such as swordfish and scalloped hammerhead, were particularly hard hit, falling by 28 percent between 1995 and 2005. Seabird ...Read Full News Humanity was genetically divided for as much as 100,000 years in Africa Posted On: May 17 2008 A mathematician from the Tel Aviv University has claimed that the human race was genetically divided into two separate groups within Africa for as much as 100,000 years, which is roughly half of its existence.This theory was put forward by Dr. Saharon Rosset from the School of Mathematical Sciences at Tel Aviv University, who worked along with team leader Doron Behar from the Rambam Medical Center ...Read Full News Interior of Mars is colder than thought Posted On: May 17 2008 New data from the U.S. space agency's Mars Reconnaissance Orbiter suggest the crust and upper mantle of Mars is stiffer and colder than thought.National Aeronautics and Space Administration scientists said the findings suggest any liquid water existing beneath that planet's surface -- and any possible organisms in the water -- would be located deeper than scientists had suspected.We found that the ...Read Full News Russian spaceship delivers food, water to International Space Station Posted On: May 17 2008 A Russian cargo spaceship has docked with the International Space Station (ISS) to deliver food, water, fuel and equipment for the crew, the Mission Control said Saturday.
