Sensor-studded clothes, carpets, and homes could track the gait of grandma or grandpa and ensure that they're not in danger of falling. The U.S. National Institute on Aging has sponsored initial research into how such wireless monitoring could better monitor the health of a growing geriatric population. The European Union has also devoted $1.5 billion to studying technologies and services for the aged.

Imagine running a Google search for basketball videos, and having your computer sift through actual footage of online videos rather than just the text of the descriptions. A new type of software could enable computers to run searches inside videos, and pick out humans and objects alike.

Last year, after untold millions of dollars, DARPA failed to renew a Lockheed program to design a UAV based on a maple tree seed. While that program, backed by tons of cash and one of the world's largest aerospace companies, amounted to bupkis, a University of Maryland project to create a maple seed UAV has finally accomplished what DARPA and Lockheed couldn't.

While the machine uprising may not be upon us just yet, a group of University of Washington researchers has conducted a study on the various threats to security and privacy that household robots currently on the market could introduce to our homes. While their findings found little to fear in the way of an I, Robot-esque revolt, it turns out common household robots can open a home to various security and privacy threats, mostly via web-enabled features that are supposed to make the robots more useful.

Time for everyone at 113 East 38th Street* to ditch the cameras, because researchers at the University of Utah have found a more subtle way to spy on your neighbors: Wi-Fi. By measuring the resistance to the radio waves that transmit wireless signals, the scientists can monitor whether or not someone is in a room at a given time.

Next time you're in Afghanistan, make sure to keep an eye out for the U.S. Army's Space and Missile Defense Command's giant blimp-like surveillance airship.

The Long Endurance Multi-Intelligence Vehicle (LEMV), as it's called, will be 250 feet long, autonomous, and able to float at up to 20,000 feet for an impressive three weeks at a time. As for its surveillance capabilities, a 40-foot-long stretch behind the cockpit will house a selection of spy gear, including a motion sensor and radar.

A text-messaging microchip planted on the patient's body significantly boosts compliance with doctor's prescriptions, according to pharmaceutical giant Novartis. That's good news for patient health and reining in healthcare costs, but a potentially worrisome development for privacy advocates.

Patients taking a drug for lowering blood pressure also received two additional gifts: tiny microchips within each pill and a shoulder-attached sensor patch.

Fret no longer, citizens of Japan, about Google's camera vans exposing the awkward moments of your private lives to millions via Street View. Because here, see? All that's behind its scary secrets is an impossibly adorable anthropomorphic camera truck in a wonderland of children's toys. Dawww, its bobbing camera head just snapped a photo of your car! It's so cute!

While Hollywood focuses on robots several times taller than humans, some researchers are building tiny robots that could fit on your fingernail. These microbots would work in swarms to collect data for a variety of applications, such as surveillance, micromanufacturing, and medicine.

The researchers, from institutes in Sweden, Spain, Germany, Italy, and Switzerland, use a novel approach to allow robots to be built cheaply and in large quantities. Working on a limited budget, they built an entire robot on a single circuit board.

In modern warfare, where missions are sometimes over in minutes, a blind enemy is a defeated enemy. The electromagnetic pulse from a nuclear weapon detonated miles aboveground would zap an army’s surveillance equipment, but not without causing heavy collateral damage. Instead, a new Air Force tool will fry electronics using high-power microwaves emitted by an unmanned aerial vehicle (UAV).
