  1. Glasses? on New Flat Lens Focuses Without Distortion · · Score: 1

    I wonder if this would work with glasses.

  2. Re:More than double? on Full Duplex Wireless Tech Could Double Bandwidth · · Score: 1

    In wired Ethernet topologies, going full duplex yields significantly more than double the throughput, since you no longer have collisions, back-offs, and re-sends. The article doesn't elaborate whether their full-duplex wireless would still be multi-access (think WiFi, with many clients on the same AP and same channels) or if each frequency would be carved out for one client and the base-station (in which case you'd see the same gains you did on wired Ethernet).

    M point is that while they cite "allow a doubling of network traffic", the reality is even better than that. Full duplex gets you more than double throughput, as well as improved jitter/latency since you no longer have to randomly re-transmit frames (or randomly wait to transmit, as with WiFi collision avoidance).

    I may be wrong, but I believe we already have "Full Duplex" in a sense as explained by you by using different frequencies for transmit and receive. The only difference here is now we can use the same frequency for transmit and receive.

  3. Re:No anomalies detected on Black Hole Blasts Neighbor Galaxy with Deadly Jet · · Score: 1

    I think it's perfectly possible for an advanced civilization to survive in that energy beam. A an engineer, one way I would approach the problem would be to use this deadly beam as a ultra massive energy resource. With that much energy coming one's way, I'm sure it's possible to create a massive electromagnetic field around the planet that would divert all harmful sub atomic particles. All it would require would be research and economic resources to pull it off.

  4. Re:Lightbending 101 on A Step Towards an Invisibility Cloak · · Score: 1

    Well, if you only bend light of the visible spectrum around someone, they could wear infrared or ultraviolet goggles to be able to see outside of this field.

  5. Re:Hey, does anyone remember that article... on Can Cell Phones Damage Our Eyes? · · Score: 1

    I just read the article, I think they were cultivated lenses from cows, so technically the cells were still alive.
