anything happening on this since 3 years?

yes it seems like. most of it seems however directed toward understanding this effect, and not toward applications. But i'm still convinced that we could find many very interesting applications !!! a few references from ADS: 1 2011PhRvA..83f3807B 1.000 06/2011 A E X R C U Brida, G.; Chekhova, M. V.; Fornaro, G.

very nice paper on adaptation of cells to microgravity

You need to avoid posting these types of links in the title as it is not managed well by plugins connected to our diigo account. Try to go to the source next time, and get rid of useless url codes.

After previously investing in the company, Google has now acquired Makani Power, a green energy startup that is currently building airborne wind turbines. The acquisition was first reported in Brad Stone's Businessweek story about Google X, and judging from Stone's story, the team will join Google X.

Interesting... however to me it looks like they have only shifted the problem... instead of looking for WIMPS now we look for X and Y and Phi...

good news for x-ray astronomers

A TED talk about Google X way of working and some closer look at the project loon (stratospheric balloon network for internet connection) by the 'moonshot captain' Astro Teller.

Get cracking, ACT AI team ;) A new X prize designed to advance artificial intelligence has been announced at the TED (Technology, Entertainment and Design) conference. The X Prize was set up to push the boundaries of technology to solve issues such as climate change. The winner, which will be announced at TED in 2020, will win $5m (£3.4m).

Deepest X-ray Image Ever Reveals Black Hole Treasure Trove An unparalleled image from NASA's Chandra X-ray Observatory gives astronomers the best look yet at the growth of black holes over billions of years beginning soon after the Big Bang.

hmmm, I was wondering how many ESA employees do know that ACT does exist....

And my son studying at Stanford (he just sent me the same link !) follows the courses this semester of two of the teachers mentioned in the article, Thrun - very good and Ng - excellent

Researchers report a new way to use X-rays to probe the properties of solid materials.

Interesting insight indeed, I see quite some overlap with the ACT mantra, athough they have 250 people and an outdoor playground.. To Teller, this failure-loving lab has simply stepped into the breach. Small companies don't feel they have the resources to take moonshots. Big companies think it'll rattle shareholders. Government leaders believe there's not enough money, or that Congress will characterize a misstep or failure as a scandal. These days, when it comes to Hail Mary innovation, "Everyone thinks it's somebody's else's job," Teller says.

nice! are they studying our website?

Wonder what is the most creative: the system or the name! NAUTILUS-X = Non-Atmospheric Universal Transport Intended for Lengthy United States X-ploration http://spirit.as.uteXas.edu/~fiso/telecon/Holderman-Henderson_1-26-11/Holderman_1-26-11.ppt

dreaming ...

The $30 million Google Lunar X PRIZE will be awarded to the first privately funded teams to build robots that successfully land on the lunar surface, eXplore the Moon by moving at least 500 meters (~1/3 of a mile), and return high definition video and imagery. The Google Lunar X PRIZE eXpires whenever all prizes are claimed, or at the end of 2015. As of midnight on December 31st, 2010, the team registration for the Google Lunar X PRIZE is closed. No additional applicants will be accepted to join the competition. ...too late

please see the act report on this from a few years ago - its on the wiki - should we maybe make an update analysis? any volunteers? Giusi?

I'll have a look

Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity. The formula, based on established physics, indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life. The simulation results made me think of Jojo's attempts to make a self-assembling space structure. Seems he may have been on the right track, just not thinking big enough

:-P Thanks Thijs... I do not agree with the premise of the article that a possible correlation of energy dissipation in living systems and their fitness means that one is the cause for the other - it may just be that both go hand-in-hand because of the nature of the world that we live in. Maybe there is such a drive for pre-biotic systems (like crystals and amino acids), but once life as we know it exists (i.e., heredity + mutation) it is hard to see the need for an amendment of Darwin's principles. The following just misses the essence of Darwin: "If England's approach stands up to more testing, it could further liberate biologists from seeking a Darwinian explanation for every adaptation and allow them to think more generally in terms of dissipation-driven organization. They might find, for example, that "the reason that an organism shows characteristic x rather than Y may not be because x is more fit than Y, but because physical constraints make it easier for x to evolve than for Y to evolve." Darwin's principle in its simplest expression just says that if a genome is more effective at reproducing it is more likely to dominate the next generation. The beauty of it is that there is NO need for a steering mechanism (like maximize energy dissipation) any random set of mutations will still lead to an increase of reproductive effectiveness. BTW: what does "better at dissipating energy" even mean? If I run around all the time I will have more babies? Most species that prove to be very successful end up being very good at conserving energy: trees, turtles, worms. Even complexity of an organism is not a recipe for evolutionary success: jellyfish have been successful for hundreds of millions of years while polar bears are seem to be on the way out.

Travel back in time and play with the original Windows 3.11. back when using a computer still meant loading EMM386 in your config.sys ;) Remember that expensive big box of hardware you were so proud of? Now the whole thing is simulated in your browser. Using JavaScript. And still runs faster. This is a collection of curated Windows 3.x software, meant to show the range of software products available for the 3.x Operating System in the early 1990s.

Awesome :) It's even got skifree!

They are developing so-called "Avatar" technology which will allow people to control robots remotely, as in the movie "Avatar." With Avatar X, they hope to revolutionize space eXploration, resource eXtraction, and other space-based activities. On the Avatar X website, it says, "AVATAR X aims to capitalize on the growing space-based economy by accelerating development of real-world Avatars that will enable humans to remotely build camps on the Moon, support long-term space missions and further eXplore space from afar."

Now we just need an x-ray mode and we are done.

Quote: Recognizing the need to investigate and evaluate visionary aerospace concepts for their validity, several organizations employ specialized groups to do just this, like ESA's Advanced Concepts Team [2], Lockheed Martin's Skunk Works [3] or NASA's Team-X [4].
