Ultra fast wi-fi nears completion  - BBC   The technology has the potential to transmit hundreds of megabits of data per second. The technology works over a range up to 10 metres and uses billions of short radio pulses every second to carry data. One of the more likely uses of UWB is to make it possible to send DVD quality video images wirelessly to TV screens or to let people beam music to media players around their home. The first products using UWB technology from Intel are due to hit the market later this year. Initially they will be products using wireless USB 2.0 connections. A rival UWB standard is being developed by Motorola and chip firm Freescale. 
Critics silenced by scans of hobbit skull  - BBC  Left:  Virtual skull of the 'hobbit', with its brain cavity highlighted.  A computer-generated model of the skull of Homo floresiensis, our diminutive human relative, confirms that the controversial specimens from Indonesia do indeed represent a new species. "Together with all the other evidence, this paper makes it very clear that H. floresiensis is not an aberrant individual with a pathological condition," says Michael Morwood, an archaeologist from the University of New England, Armidale, who was co-leader of the team. Morwood was also excited that the Falk cast seems to indicate advanced development of the front lobes of the brain, where reasoning occurs. Such brain development could be evidence for his theory that the species was able to make or refine stone tools, such as those found with the bones.

OGLE-TR-122B size comparison

Star 'gnome' is nuclear surprise  - BBC  A shining star has been located that is not much bigger than Jupiter, the biggest planet in our Solar System. The discovery is fascinating, say scientists, because it shows how small an object can be and still trigger the nuclear reactions for sunshine. What is interesting is that although OGLE-TR-122B is a mere 16% larger than Jupiter, it is actually 96 times more massive. Indeed, the density of OGLE-TR-122B is more than 50 times greater than that of our own Sun. Indeed, the density of OGLE-TR-122B is more than 50 times greater than that of our own Sun.
