From Engadget: Qualcomm Krait S4 SoC fully benchmarked, diagnosed as ‘insane’

Qualcomm Krait S4 benchmarks

We’ve seen it, touched it and we fully expect it’ll be turning heads in Barcelona next week, but until now Qualcomm’s Krait chip has largely escaped the rigors of independent benchmarking. Fortunately, AnandTech has to come to our rescue once again with a characteristically thorough analysis at the source link. Those blue and green charts can speak for themselves, but if you’re in a rush then here’s the rub of it: the Krait truly is a next-gen SoC, with the dual-core 1.5GHz MSM8960-powered reference handset delivering an “insane performance advantage” of between 20 percent and 240 percent on CPU benchmarks. As we glimpsedrecently, graphics performance is somewhat less ground-breaking but still very healthy, with the 28nm process allowing the Adreno 225 GPU to run at up to 400MHz, versus 266MHz on its Adreno 220 predecessor. Oh yes, this is going to be one mother of an MWC.

From Gizmodo: How a Man Survived Without Food For Two Months in a Snow-Buried Car

When a Swedish man drove down a deserted forest road near Umeaa, Sweden last December 19th, he was probably looking forward to Christmas. But that day, his car somehow became buried under a mountain of snow. He was trapped there for two months, suffering insanely low temperatures, with no access to food. Last Sunday, he was discovered. Alive. But how? More »

From Ars Technica: We can do no Moore: a transistor from single atom


At the center of modern technology lies the logic circuitry provided by semiconductor devices. Extending circuit logic to the realm of nanotechnology requires the construction of atomic-scale systems, which has proven challenging. Both the electric nature of individual atoms and the need to place them at specific points within a crystal lattice has kept scientists from creating atom-scale transistors until the present.

Now, a group of researchers has fabricated a single-atom transistor by introducing one phosphorous atom into a silicon lattice. Through the use of a scanning tunnelling microscope (STM) and hydrogen-resist lithography, Martin Fuechsle et al. placed the phosphorous atom precisely between very thin silicon leads, allowing them to measure its electrical behavior. The results show clearly that we can read both the quantum transitions within the phosphorous atom and its transistor behavior. No smaller solid-state devices are possible, so systems of this type reveal the limit of Moore’s law—the prediction about the miniaturization of technology—while pointing toward solid-state quantum computing devices.

From Engadget: MIT duo successfully tests wireless drug-delivery microchips, more consistent than injections

Despise those daily injections of essential medication? Well folks, relief could be on the way. Over a decade ago, two MIT professors, Robert Langer and Michael Cima, first considered developing a drug-delivery microchip that could be wirelessly controlled. This past week, researchers in Cambridge — alongside scientists from MicroCHIPS, Inc. — announced that they have successfully used the aforementioned chip to give osteoporosis patients their daily allotment of teriparatide. “You can do remote control delivery, you can do pulsatile drug delivery, and you can deliver multiple drugs,” Langer noted. Chips used in this particular study housed 20 doses each and results indicated that the delivery showed less variation than administered injections. In theory, microchips like these could be used alongside sensors that monitor glucose levels — creating tech that could adapt to changes in a patient’s condition. More info on the trial awaits in the source link below.

From Technology Review RSS Feeds: Self-Driving Tech Veers into Mid-Range Cars

Sensor technologies once limited to luxury cars are increasingly available in the mass market.

Fully autonomous self-driving cars are still far from the market, but a wide range of features—including sensor systems that warn of lane departures and imminent crashes, and can even apply the brakes if you don’t—are rapidly showing up in midmarket cars.
