nice - and we could be the first ones to propose something in the space category ... good ideas welcome! http://www.rockethub.com/projects/scifund/by_category/35-space

Movember (formerly November) is a moustache growing charity event during November. This month I am growing a moustache to raise awareness (and funds) for men's health. I will be putting a collection jar on my desk, so any donations of spare change would be very much appreciated! My 'mospace' can be found here: http://mobro.co/Lukeoc hijaking of diigo over...

Last year researchers at Imperial College London proposed that along with being used to cloak physical objects metamaterials could also be used to cloak a singular event in time. A year later, researchers from Cornell University have demonstrated a working "temporal cloak" that is able to conceal a burst of light as if it had never occurred.

Out-of-control Russian space probe may be 'most toxic falling satellite ever: A Russian space probe aiming to land on a Mars moon was stuck circling the Earth after equipment failure Wednesday, and scientists raced to fire up its engines before the whole thing came crashing down.

Is it just me, or is uncontrolled space junk re-entry becoming trendy?

this was a fantastic mission - ... what a pity!

I am a bit surprised by the number of critical comments to this article there ..

But the comments are not critical, it's just bullshitting.

exciting news ... especially now that apparently Obama proposes to cut the mars exploration programme ...

interesting reflections by MIT head on innovation in US

interesting, especially since in all COmmission papers US innovation is praised and changes expected are only related to China/India (for the better)... Article mixes a lot talk on innovation with numbers that I do not see necessarily connected (trade deficit, GDP growth etc.). Seems to me the real problematique behind the article is only the next planned distribution of federal funds and where they should cut...

well I understand her point. Spending cuts are only vicious short term solutions against economical downturn since growth (GDP is an interesting measure indeed) comes from innovation, research and production. Nonetheless, what she is describing is happening in EU too. So who will take the lead? I am not certain China is the one. In my view, it has not yet solved its domestic issues... and US still has more Nobel Prize than China. One thing for sure, the way it is EU is only a "wagon" of the train...

A new class of 2D semiconductor has been developed by researchers in the US. The free-standing quantum membranes, which are made of indium arsenide (InAs) and are just a few layers thick, have properties that are in stark contrast to the semiconductor layers used in conventional transistors.

Physicists working on the LHCb experiment at the CERN particle-physics lab have released the best evidence yet for direct charge-parity (CP) violation in charm mesons....While more data must be analysed to confirm the result, the work could point to new physics beyond the Standard Model and help physicists understand why there is more matter than antimatter in the universe.

lot of new physics this year ...

Biologists have long wondered how our organs all grow at the same rate. Now theoretical physicists think they've found a clue in the special way sandpiles grow

Nice animation...

Might be a useful reference for PyGMO-related works.

always impressive...

"Physicists have built a graphene battery that harvests energy from the thermal movement of ions in solution." Can it actually work?

...Covering about a third of the sky, the new image contains 10 times as many objects as the Palomar Survey, or about half a billion. The higher resolution scan is a goldmine for astronomers and is expected to lead to discoveries "for decades to come"...

Not really new, as it seems...

Sante: did you see this?

Maybe a stupid question: The authors argue with the results obtained by Cohen and Glashow [2]. In [2] ist was stated that superluminal neutrinos should lose energy by producing photons and e+e- pairs. This should be observable. These conslusions are based on known physics (I guess), i.e. on the laws valid for subluminal conditions. How reasonable is it to apply (i.e. to assume the validity of) the same laws for superluminal particles?

According to the company's data team, in 2008 the average amount of separation between any two given people on the network was 5.28 steps. Just three years later, it's 4.74.

trajectory calculations by no-brainers ... Newton known to primitive fishes? (can we use it for space? :-)
