This 8x10-inch sensor--about 60 times the size of a full-frame DSLR sensor--is the creation of photographer Mitchell Feinberg, who was sick of spending thousands of dollars on expensive film previews of his work. The sensor (which, he says, cost as much as "a good-sized house--before the housing crash") replaces the Polaroid backs that many photographers use to test exposure. But since these professional-grade Polaroids are so expensive these days due to their huge size and scarcity, he created this sensor (named the Maxback), which lets him see exactly how his shots would look on film, but in only 30 seconds and with no added cost. It's not to be used for regular photography--the resolution is too low for a regular print spread--but to properly simulate how his shots would look on (gigantic) film, a DSLR just wouldn't cut it.

When it comes to practicality, geodesic domes are a contractor's worst nightmare. Where can you get windows that conform to hexagonal panels? Where should you install the pipes? Would a chimney look out of place? In spite of all these questions, we spent a good portion of the 1970s and '80s touting geodesic structures as the next big suburban fad.
Back on August 11th DARPA launched, then lost, its Falcon hypersonic vehicle, also known as HTV-2. Today we found it. Not the actual glider, but a video of it streaking through the sky over the Pacific Ocean as captured by a crew member aboard a tracking ship. And as you can see in this video, it is indeed moving fast.
Whether we're engrossed in an activity or the alarm clock simply fails to chime, we've all been in situations when we say we've lost track of time. But our brains have not really lost track at all. A specific group of cells in the brain's memory center is encoding for the passage of time, researchers report. These "time cells" are key to our perception of sequences of events.
Last time we looked at the UK's teeming video surveillance technology sector we were writing about facial recognition software that Scotland Yard was trialling during the recent London riots. But facial recognition is both fraught with privacy concerns and difficult to make reliable. So researches at Kingston University are building a CCTV system that uses AI to recognise specific types of criminal behaviours--like someone brandishing a firearm--and use that to alert authorities and build a video profile of the way a crime unfolded.
Commanding an army of drones is one thing; letting drones command themselves is something else entirely, especially when they have very little in common. Boeing recently tested a swarm network to help disparate drones work together, sending two types of unmanned aerial vehicles on a reconnaissance mission over eastern Oregon.
