Researcher holds wafer (BBC) Europe moving in 'R&D slow lane'  - BBC  The figures show the bloc devoted just 1.93% of its wealth (GDP) in 2003 to this important area - compared with 2.59% in the US and 3.15% in Japan. Some emerging Asian countries, such as China, are now increasing their R&D investment to a rate where they will soon catch and overtake Europe. One factor in the stumbling performance is a slow-down in business R&D funding. Europe is now on track to miss the so-called Lisbon objective of boosting its spend to 3% of GDP by 2010. "If the current trends continue, Europe will lose the opportunity to become a leading global knowledge-based economy."  
A New Class Of Planet? - SpaceDaily  We are now able to find planets, close to their host stars, with masses comparable to that of Uranus and Neptune (14 to 17 times the mass of Earth). The interesting question, though, is: What are these things? Are they ice giants that formed several AUs out and migrated in, or are they something else? What we really need to do is to have folks go out and discover another 7 or so. We've got 3 so far. If we had 10 altogether, then we'll have enough that 1 of them, at least, should transit its star and then we'll be able to get some idea of what its density is. We've got 3 so far.   

A reconstruction of Lucy, BBC

Robotics show Lucy walked upright  - BBC  The model, which uses footprints to predict gait, suggests "Lucy", as the first fossil afarensis was called, walked rather like us. This contradicts earlier suggestions that Lucy shuffled like a bipedally walking chimpanzee. "Assuming that the early human relative Australopithecus afarensis was the maker of the Laetoli footprint trails, our study suggests that by 3.5 million years ago at least some of our early relatives - despite their small stature - could sustain efficient bipedal walking at absolute speeds within the range shown by modern humans."
