+ - Researchers create flexible, transparent, 3D non-volatile memory->

MrSeb writes "Speaking at the American Chemical Society, James Tour of Rice University has apparently demonstrated non-volatile 3D memory chips that are transparent, flexible enough to be folded like paper, and capable of withstanding temperatures up to 1,000F (537C). According to Tour, devices based on his 3D memory could survive an accidental trip to the tumble dryer, or “even a voyage to Mars.” Perhaps most excitingly, this 3D memory is fashioned from silicon oxide, an age-old, cheap, and very-well-understood darling of the semiconductor industry that can easily be manipulated using existing CMOS processes. It seems by applying voltage to the (non-conductive dielectric) silicon oxide, conductive channels of silicon nanocrystals are created — a conductive pathway that persists until a different voltage is applied. The silicon oxide needs to be fashioned into a thin channel, but apart from that Tour’s resistive switch (it's very similar to a memristor) seems very simple. Because of the simplicity and the size of the nanocrystals (5nm), Tour seems confident that this memory can achieve very high densities. The silicon oxide memory also switches very quickly (100ns), and has a high switching threshold. The tech has been patented, and it sounds like Tour is currently talking to hardware manufacturers with the hope of building screens with transparent memory built into the display."

+ - Any 4G Carrier/Hotspots combinations that don't bl

Submitted by Anonymous Coward
An anonymous reader writes "Just got a Verizon MiFi 4510L Hotspot and was disappointed to find that standard VOIP Traffic (SIP port 5060) is blocked either in the hot spot or by Verizon. Other reports (untested) suggest that other services such as Polycom style video conferencing are blocked as well.

I know how to tunnel traffic to get around these issues, (with pain and performance hits) but would prefer to return this unit and get something else.

Are there any US carriers with 4G hotspots that provide full net access without various blocks?"

Your Cat Wants Armor 3

Posted by samzenpus
What would you get if you crossed The Society for Creative Anachronism with an old cat lady? Cat armor of course. Now the age old question of whether or not a cat thrown into battle lands on its feet can be answered. To keep the playing field level, they've also made mouse armor.
