Augmented Google Earth Gets Real-Time People, Cars, Clouds

Researchers from Georgia Tech have devised methods to take real-time, real-world information and layer it onto Google Earth, adding dynamic information to the previously sterile Googlescape. They use live video feeds (sometimes from many angles) to find the position and motion of various objects, which they then combine with behavioral simulations ...

Faster than Flash, Meltable Phase-Change Device Memory Is Finally in Production

It's been 40 years in the making. This week Samsung finally announced they've kicked phase-change memory (PCM) into mass production. In a nutshell, PCM stores information by melting and freezing microscopic crystals. In gadgets like cell phones, its frozen-in-place nature means lightning-fast bootup times--instantaneous, even. Part of PCM's current appeal ...

The State of the Art of Electronic Noses

Three new e-noses use three different methods to sniff out everything from freon to fatty acids A rose by any other name would smell as sweet; we all know that. But what about a rose smelled by a non-human nose? What would it smell like? Well, an electronic nose is no Shakespeare, ...

Stumbling, Bumbling LittleDog Can Tiptoe Across Tops of Cylinders

Harvard researchers showcase new dynamic motions for the LittleDog robot Who says you can't teach robots new tricks? In this new video, Boston Dynamics' LittleDog delicately navigates a mini-forest of cylinders like a Chinese wuxia martial artist, but also shows plenty of clumsy pratfalls in the course of its training. LittleDog is ...

Carbon Nanotubes Shown to Boost Plant Growth, Could Spawn Super-Fertilizers

Carbon nanotubes have improved existing technologies in fields ranging from electrical circuitry to architecture to materials science. So is it any surprise that when researchers in Arkansas applied the miraculous microscopic structures to tomato seeds, the plants grew faster, stronger, and more plentifully? The nano-enhanced seeds experienced an increase in germination ...

Intel’s New Light Peak Cable Transfers 10 Gb/S, Puts USB To Shame

Despite the fact that optical cables transmit data far faster than copper wire, wire is still the primary medium for communication on computer chips, and between computers and devices through USB cables. But Intel hopes to change all that soon with their new Light Peak connection system. Debuted yesterday at ...

Magnetic Nanoparticles Provide Targeted Drug Release

For patients with conditions like cancer, diabetes and chronic pain, taking drugs orally is often insufficient; a more precise and flexible on/off dosing schedule controlled by an implanted device can provide better treatment based on day-to-day--or minute-by-minute--conditions. While various methods for regulating drug-dispensing implants exist (including implanted heat sources and ...

Retinal Microchip Puts Images Directly Into Brain, No Eye Needed

Blindness is the most debilitating of sensory impairments, and also the most vexing to cure. Now, MIT scientists have created a new kind of retinal implant that might help reverse the effects of two common forms of blindness. Drawing on the same principles as the cochlear implants that help the ...

Faking the Results (and Fixing the Damage Done)

Scientists consider new ways to prevent and spot research misconduct In a series of studies designed to assess two anti-tissue-rejection drugs, former University of Alabama–Birmingham surgeons Judith Thomas and Juan Contreras carefully detailed experiments in which they replaced one kidney in rhesus monkeys with a foreign one and, a month later, ...
