JOHANNESBURG, March 8 (Xinhua) -- In order to combat piracy and to improve maritime safety, South African authorities have begun using a sophisticated navigation satellite system, it was announced on Tuesday.Piracy, especially by Somalis, has been increasing along Africa east coast in recent years. The South African Press Association (SAPA) reported on Tuesday that Karl Otto, head of the South African Maritime Safety Authority (SAMSA) announced the surveillance tool at a conference in Durban.Called Long Range Identification and Tracking (LRIT), the system monitors and tracks vessels in waters south of the equator.Otto said the introduction of the LRIT followed concerns over the safety of seafarers, the safety standards of ships within South African waters.Otto said there were high levels of cargo at risk, such as fuels and oils.He said reasons for installing the system included the number of shipwrecks along the South African coast, and the threat of pollution of the marine environment by ships."It also serves as a mechanism to prevent piracy."Otto said the satellite system has the capacity to identify and track vessels up to 1,000 nautical miles (1,850 km) from the South African coastline as well as South African-flagged vessels anywhere in the world."This is a revolutionary development in the security of our seas," he said.SAMSA was determined to protect South Africa's seafarers, its coastline and the marine environment, Otto said.

BEIJING, April 12 (Xinhuanet) -- The elderly have a difficult time with multi-tasking as a study suggests that older brains behave differently when it comes to switching between two tasks, according to media reports on Tuesday.Researchers used functional magnetic resonance imaging (FMRI) to analyze brain activity in 20 people over age 60 by asking them to contemplate outdoor photos shown briefly. Then the elderly were presented with the picture of a face and asked to determine its gender and age, before being asked to recall details from the original scene they viewed.Researchers then compared their results to a similar experiment with 20 younger adults and found the brains of older subjects were less capable of disengaging from the interruption and reestablishing the neural connections necessary to switch back to focusing on the original memory."Unlike younger individuals, older adults failed to both disengage from the interruption and re-establish functional connections associated with the disrupted memory network," write Wesley C. Clapp of the University of California, San Francisco, and colleagues in the Proceedings of the National Academy of Sciences.The study, published in the online edition of the journal Proceedings of the National Academy of Sciences, sheds new lights into a growing body of studies showing that one's ability to move from one task to another in quick succession becomes more difficult with age.
