Maybe it is not yet too late for ESA to stop our plans of outsourcing IT ... Sometimes it is good to be late :-)

Maybe of interest for the ever lasting discussion around the coffee machines of our meeting room... :) paper at http://epubs.siam.org/doi/pdf/10.1137/15M1036658

A nice read. IBM Watson wowed the tech industry with a 2011 win against two of television show Jeopardy greatest champions. Using something that seemed like a sort of tree search for me IBM DeepQA algorithm managed to ingest sparse data (clues), process it getting one answer, understand what that answer means and come up with the question that leads to that answer. Now, IBM tells us that the same system can tackle medical diagnosis and financial risk problems.

Julius von Bismarck is only 28 years old, but his artistic resume is already several pages long. He's currently taking time off from school to be the new artist in residence at CERN ? the world's biggest particle physics research facility, home of the Large Hadron Collider.

Perhaps a new role for the ACT!?

very good idea - one that already Andrés had way back and a few years ago I was in contact with a group in Amsterdam who was interested but it never materialised ... any good recommendations? this Bismark guy seems to be a nice chap to have around in the office according to the photo on the site: long beard, a bottle of wine in the office and steering out of the window in search for ideas ... give the ugly office he might even want to swap it with our nice semi open space! :-)

Driverless cars will soon be a reality on the roads of Nevada after the state approved America's first self-driven vehicle licence. The first to hit the highway will be a Toyota Prius modified by search firm Google, which is leading the way in driverless car technology.

makes me think of the trend years ago to promote car-pooling and avoid 1 driver per car. The trend continues!

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?

By just getting a DNA footprint of a person scientists (and soon police) can produce an image of the person's face. Check out the pictures!

should try it the other way around, deduce the DNA from facial features. That would be even cooler.

Well actually, they did something like that as they searched for common DNA patterns in people that had similar facial features. With a large enough dataset that could provide already 24 DNA tracers that could used reliably for prediction. Imagine if you had even more data available, who needs a model then... just let the NN do it :)

Oh those bloody physicists... someone forgot to turn off the lights and now they have a 400 times better conductive crystal. If science was always that easy, I would light a candle every day.

Apparently this was not the first discovery of this effect involving SrTiO3. In an article from 2012 a conductance increase of 5 orders in magnitude is described (http://pubs.acs.org/doi/abs/10.1021/nn203991q). But indeed many large impact discoveries are accidental...

I thought we all knew already that science is just another form of directed random search :)))

Now this is a step in the right direction of the discussion we had in one of the wednesday meetings "thoughts of a biologist part 1" :)

Song birds don't eat in the morning because the added weight makes them slow and easy prey for other birds. They look for good food places during the early day and come back to eat as late as possible. Correlation of this behavior with the number of predators has been found as well...

The device, like dolphins, sends out two pulses in quick succession to allow for a targeted search for semiconductor devices, cancelling any background "noise",

Could it be used to measure ocean acidification? I found a study that links sound wave propagation with ocean acidity. Maybe we are able to do such measurement from space even? "Their paper, "Unanticipated consequences of ocean acidification: A noisier ocean at lower pH," published last week in the journal Geophysical Research Letters, found that fossil fuels are turning up the ocean's volume. Since the beginning of the Industrial Revolution, the overall pH of the world's oceans has dropped by about 0.1 units, with more of the changes concentrated closer to the poles. The authors found that sound absorption has decreased by 15 percent in parts of the North Atlantic and by 10 percent throughout the Atlantic and Pacific"

The last time I asked an oceanographer for the use of acoustic waves, she said it is still a bit problematic method to take into account its data, but we were referring to measuring ocean circulation. It may be more conclusive for PH measurements, though. The truth is that there is a whole underwater network with pulse emmitters/receivers covering the North Atlantic basin, remnant infrastructure for spying activities in the WW2 and in the cold war, that stays unexploited. We should look more into this idea

Interesting historical perspective. Progress since the late '80 really seems to be fairly slow. ?: Do we need to wait for the singularity until speech recognition works without flaws?

"I thought I would give it a try on my android sexy seems to work pretty well and I'm speaking more less at normal speed" Actually I was speaking as fast as I could because it was for the google search input - if you make a pause it will think you finished your input and start the query. Also you might notice that Android thinks it is "android sexy" - this was meant to be "on my Android. THIS seems to work...". Still it is not too bad - maybe in a year or two they have it working. Of course it might also be that I just use the word "sexy" randomly... :-\

The problem is that we don't yet understand how speech in humans actually works. As long as we merely build either inference or statistical language models we'll never get perfect speech recognition. A lot of recognition in humans has a predictive/expectational basis to it that stems from our understanding of higher lvl concepts and context awareness. Sadly I suspect that as long as machines remain unembodied in their perceptual abilities their ability to either properly recognize sounds/speech or objects and other features will never reach perfection.

Small robots that jump on water have been created by scientists and could one day be used in surveillance and search and rescue missions. The team led by Seoul National University's Je-Sung Koh studied water striders to replicate the insect's ability to propel itself from the surface of water.

"A new lightweight, energy-efficient tool for analyzing a material's chemical makeup could improve the detection abilities of various technologies, ranging from bomb-detecting drones to space rovers searching for signs of life". Raman Spectroscopy is about measuring vibrational modes in molecules. This vibrational modes are in the meV typically, turning Raman Spectroscopy into a high precision technique. This impressive work shows a new technique based on the use of optical fibers coupled to photomultipliers allowing its use, author's word, in extreme conditions such as unmanned aircraft vehicles (UAVs) and Mars/Moon rovers.

C-R-E-E-P-Y image in here...

Yeah, no doubt that's the entrance to hell... even more disturbing as it seems at least one house got in.

Yeah... I wonder if/how they plan to plug it?

How useful space technology can be for real scientific problems.

can be helpful ... but also very tricky. There are so many ways to write the same equation...

OpenKinect project http://openkinect.org/wiki/Main_Page

and yet another TO nonsense... And why always Harry Potter, dont't these darn scientists have more imagination or is their intellectual level just as low as being unable to read more complex literature than J.K. Rawling?? btw.: how about this skype session on TO, Leo?

Combine it with touchable holography (search for SIGGRAPH 2009 at youtube) and name it Holosuite 0.1.
