You might want to watch the video below before you check in, update your status, or snap and share that photo of you at lunch with your smartphone.

The Guardian got hold of this 2010 video demonstration from Raytheon, a big-time contractor that also develops things like missile systems for the Department of Defense, which shows an online tracking tool called Rapid Information Overlay Technology, or RIOT.

As Raytheon's Brian Urch explains in the video, the system takes in data about an individual from social networks including Facebook, FourSquare and GoWalla (remember, it's late 2010 in the video), … Read more

There's no disturbing lack of faith among Kickstarter supporters.

After all, a crowdfunded project to construct the Death Star that was launched less than a week ago already has nearly 1,500 backers and an astonishing $364,772 in pledges.

Well, the Rebels aren't taking that threat sitting down. A rival Kickstarter campaign to build X-wing fighters has just taken off. Its goal is to build one of the famous spaceships from "Star Wars" and then more. … Read more

In the midst of this year's particularly bad flu season, we're reminded just how many nasty little particles roam the air we breathe -- from bacteria and viruses to allergens and diesel exhaust particulates.

But a new device that recently protected immunocompromised mice from these particulates has the potential to be both effective and safe for human use as well, according to researchers behind a new study published in the journal Applied and Environmental Microbiology.

"Small particles are difficult to remove, and our device overcomes that barrier," says Pratim Biswas, who chairs the Department of Energy, Environmental & Chemical Engineering at Washington University. In fact, the device not only traps the particles, it even inactivates them -- and that includes bioterror agents, Biswas says.… Read more

The 7/7 bombings, a series of suicide blasts that took place on London's public transport system on July 7, 2005, were among the deadliest terrorist attacks of the post-9/11 world. Since then, efforts have been made to mitigate the possible damage of future attacks on public transit, and a group of British engineers from Newcastle University is doing its part by designing blast-proof trains.

SecureMetro, a collaborative project funded by the European Union, launched three years ago with the goal of developing blast-resistant and fire-proof above-ground and underground metro trains that minimize death and injury in the event of a bomb attack.

The video below shows the progress on the project. First you'll see a decommissioned train, highlighting the potential collateral damage exploding trains can cause. Doors, windows, and pieces of the carriage fly through the air. The interior of the train is also demolished, as furniture and ceiling panels prevent any survivors from easily escaping the carriage.… Read more

The world has come to this. An armor manufacturer in Maryland has created a bulletproof whiteboard designed to protect teachers and students in the event of an emergency.

Hardwire specializes in military and law enforcement armor ranging from ballistic armor panels to bulletproof shields. It's now turning its expertise in military armor towards creating armor for the classroom.

The Bulletproof Whiteboard comes with two handles on the back. If there is a threat, the teacher is supposed to take the whiteboard and hold it out. It is designed to absorb multiple clips of ammunition. The product description also says, "Blends well with classroom - no psychological impact on students."… Read more

Some 10 million people around the world seek treatment for head trauma every year, and traumatic brain injury (TBI) is predicted to become the world's third leading cause of death and disability by 2020.

The Infrascanner Model 2000, a portable intracranial hematoma detector, just may put a dent in the death rate if it helps to quickly spot potential brain bleeds in TBI victims.

The handheld device, recently approved for both military and civilian use by the FDA, uses near-infrared (NIR) tech on eight different points of the brain. Because there is a higher concentration of hemoglobin in a … Read more

If you've never seen DARPA's version of Boston Dynamics' semi-autonomous LS3 (Legged Squad Support System) robot in action, now's a good time.

The government agency released a video yesterday that highlights one of LS3's most powerful skills: the ability to follow a leader by using computer-aided vision and GPS. In the four-minute clip, you can watch the dog-like robot following an instructor over some rough terrain -- with great ease -- in a wooded area near Fort Pickett, Va. … Read more

While any soldier dreads the idea of being shot, sustaining an internal abdominal injury from an explosion or other impact can be far worse. Bleeding from wounds that can't be compressed causes some 85 percent of preventible battlefield deaths.

As part of DARPA's Wound Stasis program, Arsenal Medical has developed an injectable polymer foam that expands inside the body to stanch internal bleeding.

The concept of foam growing in the body reminds me of that 1980s B-horror film "The Stuff," but apparently it's effective.

Based on testing in pigs, DARPA says the product can control hemorrhaging in an abdominal cavity for at least an hour, a critical window to get the soldier to a medical facility. … Read more

You gotta hand it to the marketers who come up with robot acronyms. Can it get any better than Extreme Access System for Entry (EASE)?

Sounds innocuous enough, right? Until this little critter tries to float into your room to spy on you. It's one of two bots unveiled by CyPhy Works, headed by iRobot co-founder Helen Greiner.

EASE and PARC (that's Persistent Aerial Reconnaissance & Communication), a communications relay, are compact flying machines that can fly between 3 feet and 1,000 feet while remaining tethered to their human controllers via microfilaments. … Read more
