There will come a time when our homes are completely automated, just like in several horror movies in which a house slowly murders its unsuspecting occupant. The Insteon is a pretty good step towards that inevitable murder--it's the first LED lightbulb that you can control with a smartphone app.
By twisting radio waves into a threaded vortex, an international team of researchers has beamed data through the air at 2.5 terabits per second, creating what has to be the fastest wireless network ever created. Moreover, the technique used to create this effect has no real theoretical ceiling, ExtremeTech reports.
Modern lightbulbs may be getting slightly more environmentally conscious (or at least having unexpected things stuffed into them), but it's still equal parts impressive and depressing that a 100-year-old lightbulb discovered by GE (whose archives are pretty amazing) in a time capsule still works perfectly well when plugged into a circa-2012 socket. This one's a tungsten filament bulb, which was slowly brought up to 60 volts (plugging it into a regular 120-volt socket would probably not have been good) and gave off a healthy, century-old glow. Somehow though, we bet people in 1912 would have expected 2012 to be lit by something like this, not a slightly brighter and rounder version of their own bulb. Video after the jump.
Eventually, practically every conceivable pair of disparate technologies gets combined into a single package—cameras and cellphones, game consoles and e-readers, chocolate and peanut butter. The combination of speakers and lightbulbs seems like it would be one of the last ideas we'd see, but, well, the future is now. GiiNii's on-the-nose-named AudioBulb brings these strange bedfellows together for the first time.
Remember in September when neutrinos were observed moving faster than the speed of light, potentially overturning everything we thought we knew about physics? It was met with all sorts of skepticism and dubiety, so the physicists decided to replicate their experiment and take new measurements.
Well, the new results are in, and they confirm the original findings.
Using metal chips and light, clinicians will be able to detect viruses in even rural medical clinics

One of the many challenges of practicing medicine in developing countries is performing quick, reliable diagnosis of infectious disease. To bring rapid virus diagnostics to underserved populations, engineer Hatice Altug and her research team at Boston University have created and tested a biosensor that detects disease-causing organisms with precisely directed light.
Get ready to witness some James Bond-esque, HALO-style active camouflage action. Researchers at the University of Texas at Dallas have cleverly tapped the unique characteristics of carbon nanotubes and the light-bending weirdness of the mirage effect to create a kind of invisibility cloak that can be turned on and off at the flip of a switch.
On the ground, solar power has its limitations. Solar cells are not especially efficient. It rains. The sun disappears at night. A space-based solar panel can generate five times the energy of a similar panel on Earth by circumventing both weather and hours lost to darkness. A 2007 study by the National Space Society estimates that a half-mile-wide band of photovoltaics in geosynchronous orbit with Earth could generate the energy equivalent of all the oil remaining on the planet over the course of one year. Though costly, launching working solar satellites is possible today. It's transmitting the captured energy to Earth that presents a challenge—one that scientists are just starting to work on.
Optical signals could be used instead of electrical signals to stimulate cells in the body, scientists say. In a new study, researchers at the University of Utah used brief, low-power light pulses to control the actions of inner-ear cells, potentially leading to therapies that let those with auditory disorders hear the light.
