Scientists discover hidden galaxies behind the Milky Way - 1 views

  •  
    Hundreds of hidden nearby galaxies have been studied for the first time, shedding light on a mysterious gravitational anomaly dubbed the Great Attractor. Despite being just 250 million light years from Earth-very close in astronomical terms-the new galaxies had been hidden from view until now by our own galaxy, the Milky Way. Using CSIRO's Parkes radio telescope equipped with an innovative receiver, an international team of scientists were able to see through the stars and dust of the Milky Way, into a previously unexplored region of space. The discovery may help to explain the Great Attractor region, which appears to be drawing the Milky Way and hundreds of thousands of other galaxies towards it with a gravitational force equivalent to a million billion Suns. Lead author Professor Lister Staveley-Smith, from The University of Western Australia node of the International Centre for Radio Astronomy Research (ICRAR), said the team found 883 galaxies, a third of which had never been seen before. "The Milky Way is very beautiful of course and it's very interesting to study our own galaxy but it completely blocks out the view of the more distant galaxies behind it," he said. Professor Staveley-Smith said scientists have been trying to get to the bottom of the mysterious Great Attractor since major deviations from universal expansion were first discovered in the 1970s and 1980s. "We don't actually understand what's causing this gravitational acceleration on the Milky Way or where it's coming from," he said. "We know that in this region there are a few very large collections of galaxies we call clusters or superclusters, and our whole Milky Way is moving towards them at more than two million kilometres per hour." The research identified several new structures that could help to explain the movement of the Milky Way, including three galaxy concentrations (named NW1, NW2 and NW3) and two new clusters (named CW1 and CW2).

The chips are down for Moore's law : Nature News & Comment - 4 views

  •  
    Super lol for all those who abused of the law in their slides / opinions / decisions ..
  •  
    I used the law in some slides :-)! This sentence is more or less the summary "The end of Moore's law is not a technical issue, it is an economic issue,". As Moore's himself recognized last year, the Moore's law itself is a pretty wild extrapolation of one exponential growth when there were only 5 experimental points. It is remarkable however how the semiconductor industry grabbed this and made every single effort to make it true. This effort was rewarded by turning semiconductor industry into one of the most important industries worldwide. Now these are challenging times indeed, and "when tide is gone, we realize who was swimming naked"...
  •  
    The "law" is one of the most successful concrete predictions of the technological future... Still very impressive and a lot more long-lived than Moore had probably ever dreamed of :)

The Internet Archive's Windows 3.x Showcase - 4 views

  •  
    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!

'Superman memory crystal' that could store 360TB of data forever | ExtremeTech - 0 views

  •  
    A new so called 5D data storage that could potentially survive for billions of years. The research consists of nanostructured glass that can record digital data in five dimensions using femtosecond laser writing.

    Very scarce scientific info available.. I'm very curious to see a bit more in future. From https://spie.org/PWL/conferencedetails/laser-micro-nanoprocessing I made a back of envelop calc: for 20 nm spaced, each laser spot in 5D encryption encodes 3 bits (it seemed to me) written in 3 planes, to obtain the claimed 360TB disk one needs very roughly 6000mm2, which does not complain with the dimensions shown in video. Only with larger number of planes (order of magnitude higher) it could be.. Also, at current commercial trends NAND Flash and HDD allow for 1000 Gb/in2. This means a 360 TB could hypothetically fit in 1800mm2.
  •  
    I had the same issue with the numbers when I saw the announcement a few days back (https://www.southampton.ac.uk/news/2016/02/5d-data-storage-update.page). It doesn't seem to add up. Plus, the examples they show are super low amounts of data (the bible probably fits on a few 1.44 MB floppy disk). As for the comparison with NAND and HDD, I think the main argument for their crystal is that it is supposedly more durable. HDDs are chronically bad at long term storage, and also NAND as far as I know needs to be refreshed frequently.
  •  
    Yes Alex, indeed, the durability is the point I think they highlight and focus on (besides the fact the abstract says something as the extrapolated decay time being comparable to the age of the Universe..). Indeed memories face problems with retention time. Most of the disks retain the information up to 10 years. When enterprises want to store data for longer times than this they use... yeah, magnetic tapes :-). Check a interesting article about magnetic tape market revival here http://www.information-age.com/technology/data-centre-and-it-infrastructure/123458854/rise-fall-and-re-rise-magnetic-tape I compared for fun, to have one idea of what we were talking about. I am also very curious so see the writing and reading times in this new memory :)

    But how can glass store the information so long? Glass is not even solid?!

Wearable Robot Transforms Musicians into Three-Armed Drummers - 2 views

  •  
    Now this would be really cool if it had a brain computer interface and could be controlled by a trained drummer's mind! Science and Technology Society and Culture Georgia Institute of Technology researchers have built a wearable robotic limb that allows drummers to play with three arms. The two-foot long "smart arm" can be attached to a musician's shoulder. It responds to human gestures and the music it hears.

Storing energy at sea - 2 views

  •  
    The functional principle is similar to ordinary pumped storage plants: when power is needed, water flows into the sphere and drives the turbine thus generating power. If surplus power is available (usually during the night), water can be pumped out of the sphere again, thus effectively charging the storage system.
