Hasta La Gadget!

NASA satellite Voyager 1, at 36 years young, is the first man-made object in recorded history to enter interstellar space. Moreover, it’s apparently been doing so for around one year — NASA scientists at the Jet Propulsion Laboratory announced as much this afternoon, and explained how they were tipped off. “We have an instrument on board which can measure the density of ions, the plasma which is out there,” Voyager project scientist Ed Stone said in a prepared video. “In March of 2012, it turns out there was a massive eruption from the sun which eventually reached Voyager 1 in April of 2013. When that blastwave reached Voyager 1, it caused the plasma around Voyager to vibrate or oscillate in a certain particular tone. Literally the sounds of interstellar space.”

The satellite was originally launched in September 1977 in the interest of studying our own solar system as well as the interstellar medium. Having checked the first of those goals of its list, Voyager 1 is apparently head down on the second one. The satellite was thought to have reached interstellar space some time ago, but now NASA says it’s really for sure. We wish it the best of luck exploring the icy void of space between solar systems. Remember to bring a towel!

Arcade Fire already knows how to immerse its fans in a web music video. For its new “Just a Reflektor” video, though, it’s also bringing smartphones into the action. The band’s Chrome-based project links a PC to a mobile device through a webcam, turning the handheld into a visual effects controller — halos, reflections and wireframes in the video adapt to every movement. As the experiment is open source, viewers can even tinker with the web code (primarily JavaScript and WebGL) to build their own masterworks. Whether or not you’re a fan of Arcade Fire’s indie rock, you’ll likely want to give “Reflektor” a look for curiosity’s sake; just don’t be surprised when the video looks back.

Quantum cryptography is crack-proof by its nature — you can’t inspect data without changing it — but the available technology is currently limited to one-on-one connections. Toshiba has developed a quantum access networking system that could bring this airtight security to groups as large as 64 people. The approach gives each client a (relatively) basic quantum transmitter, and routes encrypted data through a central, high-speed photon detector that returns decryption keys. Such a network would not only secure entire workgroups, but lower the cost of encrypting each user. Quantum access networks won’t be useful across internet-scale distances until researchers improve the signal integrity, but there may be a time when surveillance agencies will run out of potential targets.

Kirobo, the mini-robot / Japanese Space Agency marketer, has spoken his first words in space after being launched last month. The University of Tokyo and Toyota research project wished Earth “good morning” and mouthed other space platitudes from his perch at the International Space Station. The bot can also recognize voices and will converse with astronauts as part of his mission goals. Then, after he’s lulled them into a false sense of security…

Silicon is great, but we’re tickling the edges of its speed limit. As a result, researchers at Oregon State University have been plugging away at a low-cost, faster alternative for the past three years: tiny quantum devices called metal-insulator-metal diodes, or MIM diodes for short. Silicon chips involve electrons traveling through a transistor, but MIM diodes send electrons “tunneling” through the insulator in a quantum manner, such that they appear “almost instantaneously” on the other side. The tech’s latest development doubles the insulator fun — transforming the MIM into a MIIM (pictured above) — giving the scientists another method for engineering quantum mechanical tunneling. With MIIMs, super fast transistor-less computers could be around the corner. The Oregon researchers aren’t bold enough to put a date on making any of this happen outside of the lab, but they promise entire new industries may “ultimately emerge” from their work, and we’re far too under-qualified to doubt them.
