UC Santa Barbara sues Amazon and IKEA over LED lighting
UC Santa Barbara has had enough of retailers selling its patented LED light bulb technology without authorization. This week, the university filed a lawsuit charging Amazon, IKEA, Walmart, Target and Bed Bath & Beyond with infringing its patents. According to Nixon Peabody, the law firm representing UC Santa Barbara, this is the "first-of-its-kind direct patent enforcement campaign against an entire industry."
UCSB engineers proteins that make silicon, leads hipsters to insist on organically-grown computers
Organic circuits have been in development for awhile, but it's still rare that the organics are producing the circuitry themselves. Researchers at the University of California, Santa Barbara plan to break that silence with genetically engineered proteins that can make silicon dioxide or titanium dioxide structures like those used in the computer chips and solar cells that we hold dear. The trick, the university's Daniel Morse found, is to attach silica-forming DNA to plastic beads that are in turn soaked in the silicon or titanium molecules they're looking for: after some not-so-natural selection for the best genes, the thriving proteins can produce not only substantial minerals, but whole fiber sheets. Much work is left to get the proteins producing the kind of silicon or titanium dioxides that could run a computer or power your house, but the dream is to have synthetic creations that organically produce what would normally need a mining expedition -- imagine something akin to the glass-like Venus' Flower Basket sponge (pictured above) sitting in an Intel factory. We're half-expecting organically-grown smartphones at Whole Foods, right next to the kale chips and fair trade coffee. [Image credit: Ryan Somma, Flickr]
Researchers wed quantum processor with quantum memory, quaziness ensues
Quantum computing has a long way to go before becoming truly mainstream, but that certainly hasn't stopped us from indulging in dreams of a qubit-based existence. The latest bit of fantasy fodder comes from the University of California, Santa Barbara, where researchers have become the first to combine a quantum processor with memory mechanisms on a single chip. To do this, Matteo Mariantoni and his team of scientists connected two qubits with a quantum bus and linked each of them to a memory element, capable of storing their current values in the same way that RAM stores data on conventional computers. These qubit-memory links also contained arrays of resonators -- jagged, yet easily controlled circuits that can store values for shorter periods of time. The qubits, meanwhile, were constructed using superconducting circuits, allowing the UCSB team to nestle their qubits even closer together, in accordance with the von Neumann architecture that governs most commercial computers. Once everything was in place, the researchers used their system to run complex algorithms and operations that could be eventually used to decode data encryption. The next step, of course, is to scale up the design, though Mariantoni says that shouldn't be too much of a problem, thanks to his system's resonators -- which, according to him, "represent the future of quantum computing with integrated circuits."
