Washington, June 11 : A new study has shown that people with more green space in their living environment walk and cycle less often and for shorter amounts of time.

For the study, about five thousand Dutch residents were surveyed, which involved completing a questionnaire.

The survey questions focused on participants' physical activity and self perceived health.

Researchers also calculated the percentage of green space within a 1 km and 3 km radius around the house for each resident.

"Little is known about the way in which green space exerts a beneficial effect. Several explanations are possible," said lead author of the study Jolanda Maas.

Washington, June 11 : A rare hundred-million-year old dino fossil found in Australia has led scientists to suggest a link between South American and Aussie dinosaurs.

According to a report in National Geographic News, the fossil belonged to a two-legged meat eater, or theropod, that is closely related to Megaraptor namunhuaiquii, a giant, big-clawed carnivore from Argentina.

The discovery could help redraw the world map during the dinosaur era, researchers said.

That’s because the newfound Australian dinosaur shows that animals could travel across the prehistoric supercontinent of Gondwana during the Cretaceous period, about
145 to 65 million years ago.

This in turn suggests that Gondwana’s Southern Hemisphere landmasses broke up later than traditionally thought.

Washington, June 11 : The Arecibo Observatory in Puerto Rico became a part of the global network of telescopes in North America, South America, Europe, and Africa when all of them simultaneously observed the same targets recently, simulating a telescope more than 6,800 miles in diameter.

The telescopes joined by the observatory managed by Cornell's National Astronomy and Ionosphere Center were all members of the Express Production Real-time e-VLBI Service (EXPReS) project.

They all marked a live demonstration of their first four-continent, real-time, electronic Very Long Baseline Interferometry (e-VLBI) observations on May 22.
