Great Red Spot storm heating Jupiter's atmosphere, study shows
By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Scientists have long wondered why Jupiter's upper atmosphere has temperatures similar to those of Earth, even though the biggest planet in the solar system is five times farther away from the sun. The answer may be The Great Red Spot, an enormous storm big enough to swallow three Earths that has been raging on Jupiter for at least three centuries, a study showed on Wednesday. Using an infrared telescope at Hawaii's Mauna Kea Observatory, scientists discovered that the upper atmosphere above the Great Red Spot – the largest storm in the solar system - is hundreds of degrees hotter than anywhere else on the planet.

New crop of robots to vie for space in the operating room
By Susan Kelly CHICAGO (Reuters) - Even though many doctors see need for improvement, surgical robots are poised for big gains in operating rooms around the world. Within five years, one in three U.S. surgeries - more than double current levels – is expected to be performed with robotic systems, with surgeons sitting at computer consoles guiding mechanical arms. Robotic surgery has been long dominated by pioneer Intuitive Surgical Inc, which has more than 3,600 of its da Vinci machines in hospitals worldwide and said last week the number of procedures that used them jumped by 16 percent in the second quarter compared to a year earlier.

Scientist Brian Cox holds summer master class in London for kids
British physics professor Brian Cox taught students at St. Paul's Way Trust School in London on Tuesday how to create fire with methane gas. The school is hosting a science summer school and invited the celebrity physicist, who says he hopes the project will bring in those from different backgrounds. "There is no shortage of enthusiasm for students and young people when you talk about science and engineering," Cox said.

Healthy clones: Dolly the sheep's heirs reach ripe old age
By Ben Hirschler LONDON (Reuters) - The heirs of Dolly the sheep are enjoying a healthy old age, proving cloned animals can live normal lives and offering reassurance to scientists hoping to use cloned cells in medicine. Dolly, cloning's poster child, was born in Scotland in 1996. Now researchers have allayed those fears by reporting that 13 cloned sheep, including four genomic copies of Dolly, are still in good shape at between seven and nine years of age, or the equivalent of 60 to 70 in human years.

Meter-wide dinosaur print, one of largest ever, found in Bolivia
A footprint measuring over a meter wide that was made by a meat-eating predator some 80 million years ago has been discovered in Bolivia, one of the largest of its kind ever found. The print, which measures 1.2 meters (1.3 yards) across, probably belonged to the abelisaurus, a biped dinosaur that once roamed South America, said Argentine paleontologist Sebastian Apesteguia, who is studying the find. The print was found some 64 kilometers (40 miles) outside the city of Sucre in central Bolivia by a tourist guide earlier this month.
