Crowsourcing Awareness: "To augment the use of these space technologies, virtual communities of group intelligence - called "Crowdsourcing" - can aide in emergency planning and post-disaster coordination."

Commit Assist Tool allows predicting bugs in large code bases typically found in AAA-games.

EXACTLY what I wanted to investigate as a rapid constuction tool for shape memory alloy structures!

ridiculous next frontier for patenting ... mathematics!!!!!

should I take these as an indication of news from the bankers concerning your business case?

this would trigger innovation, and kill mathematics! The world is crazy... imagine a mathematician that will have to pay to use a demonstration for his own demonstration... haha. And the interviewed guy in the article say that this would benefit mathematicians !!! what a joke ! And all the schools that will have to pay billions to Euclid's heirs ! This would kill physics too, and all domains that use mathematics as a tool !

Very interesting presentation on how the brain can back-propagate error signals during learning (using time-derivatives to encode errors). Hinton discusses how back-propagation can be achieved with very limited / unsophisticated tools and in excessively noise environments.

There has been much recent interest in accelerating materials discovery. High-throughput calculations and combinatorial experiments have been the approaches of choice to narrow the search space. The emphasis has largely been on feature or descriptor selection or the use of regression tools, such as least squares, to predict properties. The regression studies have been hampered by small data sets, large model or prediction uncertainties and extrapolation to a vast unexplored chemical space with little or no experimental feedback to validate the predictions. Thus, they are prone to be suboptimal. Here an adaptive design approach is used that provides a robust, guided basis for the selection of the next material for experimental measurements by using uncertainties and maximizing the 'expected improvement' from the best-so-far material in an iterative loop with feedback from experiments. It balances the goal of searching materials likely to have the best property (exploitation) with the need to explore parts of the search space with fewer sampling points and greater uncertainty.

Can AI create the next wonder material? http://www.nature.com/news/can-artificial-intelligence-create-the-next-wonder-material-1.19850?WT.ec_id=NATURE-20160505&spMailingID=51301208&spUserID=MTEzODM0NjYzMzgS1&spJobID=920498312&spReportId=OTIwNDk4MzEyS0

"scientists at Harvard University say they've modified the CRISPR method so it can be used to effectively reverse mutations involving changes in one letter of the genetic code. That's important because two-thirds of genetic illness in humans involve mutations where there's a change in a single letter."

"Efficient introduction of specific homozygous and heterozygous mutations using CRISPR/Cas9" http://www.nature.com/nature/journal/vaop/ncurrent/full/nature17664.html?WT.ec_id=NATURE-20160428&spMailingID=51249830&spUserID=MTEzODM0NjYzMzgS1&spJobID=903461217&spReportId=OTAzNDYxMjE3S0 As posted here previously, the number and importance of CRISPR is growing steadily, but still plenty of work to make it a reliable tool. Maybe, next work for the Molecular Engineering RF?

The International Space Apps Challenge is now over, it is interesting to have a look at the solutions ...

what sort of "app" is this e.g. http://spaceappschallenge.org/challenge/brightest-night/solution/132 "We started of by trying to set our camera in raw mode, howsoever this can't be done for current logitech modules and without a high risk of permanently destroying the camera (reflashing the EEPROM). we use a logitech c920 and captured a raw image from it using guvcview on ArchLinux we then wrote some python code to calculate the average BGR value of our Image. We are currently workin on automiztion, but this will take much longer as there will be a lot of reverse engineering of the USB-Protocol needed."

c'mon really! To name a few: - Tour of the Solar System ... that is one of the numerous specialities of the ACT. - Satellite data correlation tool ... solution is flawed, but I really like the idea. Lot of added value. I definitely think are interestung stuffs to do there for cheap. - Aurora project: Model & Data ... space weather not interesting?! - Kepler ... a classic Do not expect the solutions to be tremendous just after 3 days of work, but the proposed list of challenges are "seeds" for innovation to me.

"Despite the dramatic shift toward simplification in software interfaces, the world of development tools continues to shrink our workspace with feature after feature in every release. Even with all of these things at our disposal, we're stuck in a world of files and forced organization - why are we still looking all over the place for the things we need when we're coding?"

We made it to Slashdot's frontpage !!! :)

Congratulations, gentlemen!

Looks fantastic!

Sounds like a great tool for calculation and may provide some deeper understanding. But: I think their comments about space and time are misleading. Often you can ignore space and time when you just want the probability of an event (and it makes your calculations easier) but especially in the low-energy regime an event is clearly localized.

where is Luzi? where is Anna? where is Sante? when you need them?

NASA answer to the big data hype

"The service encompasses selected NASA satellite and global change data sets -- including temperature, precipitation, and forest cover -- and data processing tools from the NASA Earth Exchange (NEX)" Very good marketing move for just three types of selected data (MODIS, Landsat products) plus four model runs (past/projection) for the the four greenhouse gas emissions scenarios of the IPCC. It looks as if they are making data available to adress a targeted question (crowdsourcing of science, as Paul mentioned last time, this time climate evolution), not at all the "free scrolling of the user around the database" to pick up what he thinks useful, mode. There is already more rich libraries out there when it comes to climate (http://icdc.zmaw.de/) Maybe simpler approach is the way to go: make available the big data sets categorized by study topic (climate evolution, solar system science, galaxies etc.) and not by instrument or mission, which is more technical, so that the amateur user can identify his point of interest easily.

They are taking a good leap forward with it, but it definitely requires a lot of post processing of the data. Actually it seems they downsample everything to workable chunks. But I guess the power is really in the availability of the data in combination with Amazon's cloud computing platform. Who knows what will come out of it if hundreds of people start interacting with it.

The catalog, a master list organized into 15 categories, is intended for industry, academia, other government agencies, and general public. The catalog covers technology topics ranging from project management systems, design tools, data handling, image processing, solutions for life support functions, aeronautics, structural analysis, and robotic and autonomous systems. NASA said the codes represent NASA's best solutions to an array of complex mission requirements. McMillan reported that "Within a few weeks of publishing the list, NASA says, it will also offer a searchable database of projects, and then, by next year, it will host the actual software code in its own online repository, a kind of GitHub for astronauts."

"A band of space hackers and engineers are trying to do something never done before - recover a 36 year old NASA spacecraft from the grips of deep space and time. With old NASA documents and Rockethub crowdfunding, a team led by Dennis Wingo and Keith Cowing is attempting to steer ISEE-3, later rechristened ICE, the International Cometary Explorer, back into an Earth orbit and return it to scientific operations. Dennis says, 'ISEE-3 can become a great teaching tool for future engineers and scientists helping with design and travel to Mars'. Only 40 days remain before the spacecraft will be out of range for recovery. A radio telescope is available, propulsion designs are in hand and the team is hoping for public support to provide the small amount needed to accomplish a very unique milestone in space exploration

well, most good ideas probably take only a second to be formulated, it's the details that take years :-)

I do not think the point of the SU is to formulate new ideas (infact there is nothing new in the projects chosen). Their mission is to build and maintain a network of contacts among who they believe will be the 'future leaders' of space ... very similar to our beloved ISU.

"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.

I'm sure Francesco will love it... perhaps of use for ACT's Google calendar/docs?

is there an easy way (easy for Francesco I mean) to retrieve the citation number of papers in google scholar automatically (e.g. for act papers)?

It seems like google scholar is not supported yet.

Could be fun actually... I liked most the part: "They were asked to (...) find food: meaning fishing, trapping animals, preparing food and cooking with primitive tools.". Roasted squirrel anyone?

nice application of cloud computing
