Researchers have developed an implantable sensor that can monitor blood-sugar levels and send the data wirelessly to an external receiver. The team has used the device in pigs for over a year, and is hoping it will work successfully in humans with diabetes.
Astronomers have serendipitously found soccer-ball shaped carbon molecules in the nebula around a distant, white-dwarf star. The molecules are the largest ones ever found in space, and are part of a third type of carbon–the other two being graphite and diamond.
A type of moss called ‘Sphagnum’ has a peculiar way of launching its spores so that they rise high enough in the air to be dispersed by winds. As the spores are released from the moss’ capsules—only about a centimetre above the ground—they form tiny mushroom clouds, helping them rise at least 10 cm up in the air, a study in Science finds (doi: 10.1126/science.1190179).

The independent Committee on Climate Change (CCC) has advised the UK government to increase investment in low-carbon technologies in order to boost green, economic growth and to achieve the target of cutting greenhouse gas emissions by 80% by 2050—relative to 1990 levels. The findings were published today in a report to the Government’s Chief Scientific advisor, Sir John Beddington.
The European Space Agency’s (ESA) comet-chasing probe Rosetta has captured the first close-up images of the asteroid Lutetia (ESA, BBC). “It’s a new world discovered by Rosetta and it will keep scientists busy for years,” said Holger Sierks, the principal investigator on the Osiris camera system (BBC). At 18:10 CEST on 10 July, the probe—equipped with cameras, spectrometers, magnetic-field experiments and more—passed within 3162 km of Lutetia. The flyby itself was very brief—lasting only about a minute—as Rosetta swept past the asteroid at a speed of 15 km/s. The 400 images that were attained during the fly-by are now being … Read more
A biology professor at the University of Alabama at Huntsville (UAH) has been charged with capital murder in the shooting deaths of three professors during a biology faculty meeting yesterday. Three other people were wounded. Read more
