Analysis of a recent Java flaw exploited by the Flashback Trojan reveals that more than 550,000 Macs were affected in the U.S. and abroad, according to anti-virus vendor Doctor Web. "This once again refutes claims by some experts that there are no cyber-threats to Mac OS X," Doctor Web said in a Tuesday blog post. lol :)

Not so good news ...

Have a look at the US budget and the incredible amount of money they are spending for military purposes. It's as simple as that.

Liquid solar cells are pretty neat, to be sure, but current-generating paint can be a hard color to match. Good thing, then, that researchers at Rice university have developed the perfect complement: a spray-on battery.

interesting workshop on language here in Leiden ... Luis, Giusi??

interesting indeed, but the lectures I'd be interested in already took place

No good, 80% of these people are top quoted in my research area... I really should have been there. Evidently the organisers need to work on advertising.

Check the landing video from the onboard camera - Guido: how well would our optical flow algorithm cope with such images? Looks quite complicated to me....

Note that videos there are said to be "thumbnail" quality, so I think videos with higher resolution (and possibly frame rate) have been acquired, just that they were not downloaded yet.

any of the geeks tried this already? Francesco?

nobody ... you are not as geeky as I thought ...

Tomorrow, at 9am EST, scientists at the Large Hadron Collider (LHC) at CERN in Switzerland are expected to announce, with fairly strong certainty, that they have observed the Higgs boson "God" particle at a mass-energy of 125 GeV. For just over a week, rumors have been rife that observations with 2.5 to 3.5 sigma certainty (96% to 99.9%) have been made.

see papers I have just sent you this afternoon ...

looks like a reasonably and interesting guy !

Yeah... He's obviously too clever to go for a blatant copyright infringement, so I'm curious what was he up to. Perhaps all he wanted was just JSTOR's overreaction?

Excluding all mine, which ACT paper contains False claims?

The Allen Telescope Array (ATA) is once again searching planetary systems for signals that would be evidence of extraterrestrial intelligence. Among its first targets are some of the exoplanet candidates recently discovered by NASA's Kepler space telescope.

amusing take on innovation A tiny number of ideas can go a long way, as we've seen. And the Internet makes that more and more likely. What's happening is that we might, in fact, be at a time in our history where we're being domesticated by these great big societal things, such as Facebook and the Internet. We're being domesticated by them, because fewer and fewer and fewer of us have to be innovators to get by. And so, in the cold calculus of evolution by natural selection, at no greater time in history than ever before, copiers are probably doing better than innovators. Because innovation is extraordinarily hard. My worry is that we could be moving in that direction, towards becoming more and more sort of docile copiers.

Earth's irregular natural satellites (NES) that are temporarily captured from the near-Earth-object (NEO) population. --> Possibly interesting for NEO exploration? http://arxiv.org/abs/1112.3781

How early could we detect these coming?

A simple cube open at the top can increase the annual energy density generation by a factor (depending on the latitude) of 2 - 3.8 compared to a flat horizontal panel, versus an increase by a factor of 1.3 - 1.8 achieved from a flat panel using dual-axis tracking. Genetic algorithm are used to optimize the energy production in a day for arbitrarily shaped 3D solar cells confined to a given area footprint and total volume doi:10.1063/1.3308490 could be interesting to investigate

Physicists in Germany have developed the first-ever "nano-ear" capable of detecting sound on microscopic length scales with an estimated sensitivity that is six orders of magnitude below the threshold of human hearing.

one can see that you are in bed and bored :-)

"...scientists in Germany have built a device that can effectively make objects invisible to sound waves. The performance of the acoustic "invisibility cloak" exceeds that of existing electromagnetic devices and could open up new ways of manipulating waves, including the development of shields against seismic waves."

shit.... they are a few months ahead of us it seems ... :-( what is the impact on our ariadna??

An international team of researchers have developed a new type of gyroscope that is the first to measure the "wobble" in the rotational axis of the Earth from a ground-based laboratory. Astronomers normally track this wobble by continuously monitoring the position of distant objects, such as quasars. But this new method will provide a much simpler and cheaper alternative to these large-scale astronomical readings, the scientists claim.

is this of any use for spacecraft?

mmm it's like saying that you can replace satellite tracking by accelerometers on-board satellites... for Leo: you'd better put an atomic gyro on a spacecraft these laser gyro are huge !

Researchers in South Korea are the first to make a bendable digital memory that can store data without constant power. Such memories could find applications in electronic paper for more comfortable reading and in wearable computers, which could be used in medical monitoring and treatment.

Blog posts describing the approaches followed by the contestants that ranked 1st, 2nd and 3rd.

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.
