KING OF PREDATOR OF ALL TIME

                                   Scientists have discovered a fossilized tooth belonging to the vicious Tyrannosaurus Rex dinosaur, which they claim provides solid evidence that the creature was indeed a predator, hunter and killer, and not a scavenger as some paleontologist suggested previously. Tyrannosaurus Rex has long been popular as the most notorious, vicious killing creature to roam the planet during the age of the dinosaurs.

                                   For more than a century some paleontologists

have argued that Tyrannosaurus Rex was a scavenger, not a predator. From this new study it is almost sure that the previous theory was not true and the Tyrannosaurus Rex were the King of the predators of all era. 

ARCTIC AFTER 2058

                               Arctic may become ice free for several months of the year, starting sometime during the years 2054 to 2058, a combined team of researchers from the US and China has predicted. Using a climate simulation tool, scientists have projected that the Arctic will become September ice free after the next 40 years, ice-free in this context refers to a time period during any year, more specifically, during the September after withstanding the heat of summer, researchers said.

                           A warmer planet would mean warmer temperatures in the Arctic- enough warming and Arctic would eventually become ice-free during part of the year, the most alarming is that, when all the ice melted, the sea level will risen very high, so many parts of the lands will gone beneath the sea.

ASTRONAUT DRIVES ROBOT ON EARTH, AT FIRST

                                           NASA transformed the international space station into a command center for a robot on the earth this month for a first of its kind test drive of the technology and skills needed to remotely operate the robot on the moon, mars or and asteroid.

                                          During the June 17 space technology test, NASA astronaut  Chris Cassidy, a space station flight engineer, remotely controlled a K10 rover at the agency's Ames Research Center in Moffett field, Calif. The robot was commanded to simulate deploying a polyimide-film antenna in a specially built "Roverscape" at the NASA center.
                                         On the space station, Cassidy received telemetry and real time video from the rover and monitored the robot's reaction to his commands via virtual terrain display.
