NASA has 50 years of experience with reentry capsules, but is fearful of trying something new. SpaceX has no reentry experience and chooses the most efficient engineering approach. Guess whose capsule is overweight and still sitting on the ground? Guess whose capsule completed a successful first flight yesterday?

Les Hatton, an international expert in software testing resident in the Universities of Kent and Kingston, carried out an extensive analysis of several million lines of scientific code. He showed that the software had an unacceptably high level of detectable inconsistencies.

haha. this guy won't have any new friends with this article! I kind of agree but making your code public doesn't mean you are doing good science...and inversely! He takes experimental physics as a counter example but even there, some teams keep their little secrets on the details of the experiment to have a bit of advance on other labs. Research is competitive in its current state, and I think only collaborations can overcome this fact.

well sure competitiveness is good but to verify (and that should be the case for scientific experiments) the code should be public, it would be nice to have something like bibtex for code libraries or versions used.... :) btw I fully agree that the code should go public, I had lots of trouble reproducing (reprogramming) some papers in the past ... grr

My view is that the only proper way to do scientific communication is full transparency: methodologies, tests, codes, etc. Everything else should be unacceptable. This should hold both for publicly funded science (for which there is the additional moral requirement to give back to the public domain what was produced with taxpayers' money) and privately-funded science (where the need to turn a profit should be of lesser importance than the proper application of the scientifc method).

well.. i'd better live decently than get rich... which is not possible in Paris (take 1680 euros for one family and a 1000 euros rent, minus all normal expenses (health, car, insurance, ...), it's difficult to finish the month...) Without mentioning that in France you would become an underpaid secretary...!!! My ex phd director is a professor and she doesn't even have a secretary to manage the 150 applications to the master she is in charge... My experience would rather say that the salary and the time you have for research are quite decorrelated.

Sure, 44k for a full professor, that's a bad joke! Just my experience from conferences: high saleries do not make good research, I rather suspect there's something like an optimal salery. People with too high saleries often seem to feel obliged to make much noise (whatever the reason might be), the result is not research but PR campagns.

I agree ! Just a correction, net salary for a full professor starting in France: 36456 euros/year... For a McF (equivalent junior prof.): 20160 euros/year, and of course a shitload of admistrative tasks and teaching. I don't know why i still dream to have a position...?

We present the application of Principal Component Analysis for data acquired during the design of a natural gesture interface. We investigate the concept of an eigengesture for motion capture hand gesture data and present the visualisation of principal components obtained in the course of conducted experiments. We also show the influence of dimensionality reduction on reconstructed gesture data quality.

And here's the arXiv paper http://arxiv.org/abs/1109.4897 Serious? Difficult to say. I'm theorist and can't really rate their measurement techniques. Certainly be cautious, mostly such things disappear faster than they appeared.

Leo, you mean that they measured 3 years? That's not a point to criticize: since the only interaction of neutrinos with matter is the Weak Interaction (which is indeed very, very weak), it is extremely hard to get a reasonable statistic. By the same reason, it's essentially impossible to shield the experiment from the background. And this background (solar neutrinos, cosmic radiation neutrinos) is huge.

for sure a result to be taken seriously. It makes a buzz in my lab... but always be cautious with this kind of declaration, that hugely violates all physics we know and even most of the reasonable alternative theories... Remember the Pionneer anomaly for which it took almost ten years to set up that finally its a thermal effect.
