Washington, February 13: Biofuels crops being grown as an effort to deal with global warming are indeed increasing greenhouse gas emissions rather than decreasing them, two studies have established.

One analysis suggests that clearing forests and grasslands to grow biofuel crops releases vast amounts of carbon into the air, far more than the carbon spared from the atmosphere by burning biofuels instead of gasoline.

"We're rushing into biofuels, and we need to be very careful. It's a little frightening to think that something this well intentioned might be very damaging," the Environmental News Network quoted Jason Hill, an economist and ecologist at the University of Minnesota, as saying.

Washington, Feb 13: An international team of scientists from Europe, Israel and the US are developing robotic rats, which will aid in rescue missions.
Based on principles of active sensing adopted widely in the animal kingdom, the multinational team is developing innovative touch technologies, including a 'whiskered' robotic rat, which will be able to quickly locate, identify and capture moving objects.
'The use of touch in the design of artificial intelligence systems has been largely overlooked, until now,' said Professor Ehud Ahissar of the Weizmann Institute of Science’s Neurobiology Department, whose research team is one of the groups participating in the multinational project.
