Hidden Networks, Dissolving Sensors, Spies Spy, and Redirected Walking

  1. Big Bang Data: Networks of London (YouTube) — guide to the easy-to-miss networks (fibre, CCTV, etc.) around Somerset House, where an amazing exhibition is about to launch. The network guide is the work of the deeply talented Ingrid Burrington.
  2. Sensors Slip into the Brain and then Dissolve When Done (IEEE Spectrum) — pressure and temperature monitors, intended to be implanted in the brain, that completely dissolve within a few weeks. The news, published as a research letter in the journal Nature, described a demonstration of the devices in rats, using soluble wires to transmit the signals, as well as the demonstration of a wireless version, though the data transmission circuit, at this point, is not completely resorbable. The research was published as a letter to Nature.
  3. GCHQ Proposes Surveillable Voice Call Encryption (The Register) — unsurprising, but should reiterate AGAIN that state security services would like us to live in the panopticon. Therefore, don’t let the buggers anywhere near the reins of our communication systems.
  4. These Tricks Make Virtual Reality Feel RealScientists are exploiting the natural inaccuracies in people’s own proprioception, via a technique called “redirected walking,” to create the perception of space where none exists. With redirected walking, […] users can sense they are exploring the twisting byways of a virtual city when in reality they are simply walking in circles inside a lab. Original Redirect Walking paper.
