London, Nov 12: While it has been known that some species of birds use the alarm calls of other bird species to flee danger, how they develop this ability has been unknown. Now, a team of Australian researchers has found that birds develop this multilingual ability by learning the alarm calls of other birds on the job.

In the study, associate Professor Robert Magrath and colleagues of the School of Botany and Zoology at the Australian National University in Canberra found that fairy-wrens have the ability to learn the alarm calls of other species, giving them the edge when it comes to escaping predators.

For the study, the researchers played recordings of calls of different bird species to fairy-wrens (Malurus cyaneus) and monitored their response.

London, Nov 12: The European Space Agency (ESA) is planning to offer zero-gravity rides to passengers on an airplane, giving a boost to the fledging space-tourism market.

According to a report in New Scientist, the airplane would fly in a cycle of steep 45 degree climbs and shallower 30 degree dives, providing snatches of weightlessness as it goes over the top and starts each descent.

This parabolic technique has been used for decades to train astronauts, test equipment for space programmes and for scientific research, with planes taking part in NASA’s programme being dubbed “vomit comets”.
