DARPA and the US Army have taken the wraps off ARGUS-IS, a 1.8-gigapixel video surveillance platform that can resolve details as small as six inches from an altitude of 20,000 feet (6km). ARGUS is by far the highest-resolution surveillance platform in the world, and probably the highest-resolution camera in the world, period.
ARGUS, which would be attached to some kind of unmanned UAV (such as the Predator) and flown at an altitude of around 20,000 feet, can observe an area of 25 square kilometers (10sqmi) at any one time. If ARGUS was hovering over New York City, it could observe half of Manhattan. Two ARGUS-equipped drones, and the US could keep an eye on the entirety of Manhattan, 24/7.
It is the definition of “observe” in this case that will blow your mind, though. With an imaging unit that totals 1.8 billion pixels, ARGUS captures video (12 fps) that is detailed enough to pick out birds flying through the sky, or a lost toddler wandering around. These 1.8 gigapixels are provided via 368 smaller sensors, which DARPA/BAE says are just 5-megapixel smartphone camera sensors. These 368 sensors are focused on the ground via four image-stabilized telescopic lenses.
ARGUS’s insane resolution is only half of the story, though. It isn’t all that hard to strap a bunch of sensors together, after all. The hard bit, according to the Lawrence Livermore National Laboratory (LLNL), is the processing of all that image data. 1.8 billion pixels, at 12 fps, generates on the order of 600 gigabits per second. This equates to around 6 petabytes — or 6,000 terabytes — of video data per day. From what we can gather, some of the processing is done within ARGUS (or the drone that carries it), but most of the processing is done on the ground, in near-real-time, using a beefy supercomputer. We’re not entirely sure how such massive amounts of data are transmitted wirelessly, unless DARPA is waiting for its 100Gbps wireless tech to come to fruition.
The software, called Persistics after the concept of persistent ISR — intelligence, surveillance, and reconnaissance — is tasked with identifying objects on the ground, and then tracking them indefinitely. As you can see in the video, Persistics draws a colored box around humans, cars, and other objects of interest. These objects are then tracked by the software — and as you can imagine, tracking thousands of moving objects across a 10-square-mile zone is a fairly intensive task. The end user can view up to 65 tracking windows at one time.
Eighteen human heads shipped from Rome and apparently bound for a research facility in the United States are being held up by customs officials at O'Hare International Airport pending an investigation, officials say.
In a few years, 3D printers will become a consumer electronics commodity. Today you can buy a MakerBot Thing-O-Matic, “the latest in cutting edge personal manufacturing technology,” for $2,500. You can plug it into your computer via USB, load up some freely-available 3D modeling software, and print stuff; it really is that simple. The only real barrier to mass adoption is the initial purchase price, and the printing material itself isn’t cheap either.
Both of these costs will tumble in coming years, however. Printing — or additive manufacturing — techniques will improve. 3D printers will speed up, and the choice of colors and finishes will expand. For now these magical printers are just the plaything of prototypers, inventors, and gadgeteers, but sooner rather than later they will find a place in the home. To begin with they will be attached to a family computer, but it’s safe to assume that wireless versions that can sit on the kitchen worktop won’t be far behind.
Some people will do anything to turn the heads of the opposite s-x, but this doesn’t seem like a good move. Datta Phuge of India wants a woman so badly that he spent $22,754 (£14, 000) on a gold shirt.
The material created by the Stanford research team is made of plastic polymer and tiny pieces of nickel. The team cut the material over 50 times with it healing almost completely each time in less than 30 minutes.

Lately, it seems like nearly everything has been reproduced by a 3D printer. Between the group that 3D printed a gun, the people who printed a drone, and the army of items sold at this small marketplace for 3D printed goods, there are plenty of novelty uses for these suddenly trendy machines. We’re a long way from 3D printing a house, but it’s clear that the hobby is inching into the mainstream. Yet it’s difficult not to wonder: at what point will 3D printing move beyond novelty to industry? Will these machines change the way we manufacture goods, and subsequently change the global economy, too? (Is it already happening before our very eyes?)
