London, Jan 8: Chemical engineers in the US have created the world''s smallest working fuel cell, which may lead to the development of environmentally-friendly portable gadgets in future.

At just 3 millimetres across, future versions of the tiny hydrogen-fuelled power pack will be able to store more energy than batteries and that too in the same space.

Still, it's easier to make batteries at the small scale than the pumps and control electronics of a fuel cell.

In fact, small pumps tend to utilise more energy than they generate.

Washington, Jan 8: Space is not as far from the Earth's surface as people think, for scientist have discovered that the ionosphere, the layer of electrically charged particles that comprises the outer atmosphere, is thinner than expected, and cooler too.

Knowledge of the shape and size of the ionosphere may help in determining how particularly dense regions within it may distort radio, radar and navigation signals, which can make communications and satellite-based systems less reliable.
