Researchers hack drones. A science project anyone?

My son Benjamin once got honorable mention for his science project, which consisted of going to a firing range and seeing whether silk is really bulletproof, as it's sometimes purported to be. The guy at the range smiled upon hearing about what the skinny teenager was up to and said the silk would never stand up to I-forget-what-caliber of bullet.

He was right. The piece of material Benjamin brought to the range didn't hold its lead. (The shooting range guy pulled the trigger because Benjamin didn't have his gun license yet. He's 26 now, and still doesn't, but he did learn how to drive, in the meantime, but not a stick shift.)

Anyway, his offering blew away all of the volcano projects in his class at Hunter College High School. That was then. In the past 10 years, and, in fact, in the past 10 days, prospects for perversely cool science projects have gotten a lot better.

Case in point: Todd Humphreys and his team from the Radionavigation Lab at the University of Texas at Austin reportedly demonstrated last week in front of Department of Homeland Security officials that it is relatively easy to take control of an airborne drone by hacking into its GPS system. This is not jamming the signal, perhaps what happened to the U.S. drone brought down in Iran. This is "spoofing," in which you actually become a ground-based pilot.

The cost to convert a drone "on the fly" into your own version of the world's best remote-controlled hobby airplane ever: $1,000, actually, not much more than the list price for a high-end iPad.

The worry, of course, is that someone co-opts the technology for something other than science projects—and I don't mean forest fire surveillance. One drone demo took place over an Austin stadium, according to Fox News, which broke the story. And Humphreys was quoted by Fox: "What if you could take down one of these drones delivering FedEx packages and use that as your missile? That’s the same mentality the 9-11 attackers had.”

The Department of Homeland Security is supposed to be dealing with all of this, but doesn't seem to have gotten very far, hence the rationale for Humphreys' commandeered flyby. Maybe a skinny high school kid can underline some of the vulnerabilities to the public and government officials better than a college professor. After all, guns are so nineties.

Let's see what happens from here. At the very least, though, Humphreys' demo is likely to vie with genetically modified bird flu for the top spot on the existential dread list.

Gary Stix, Scientific American's neuroscience and psychology editor, commissions, edits and reports on emerging advances and technologies that have propelled brain science to the forefront of the biological sciences. Developments chronicled in dozens of cover stories, feature articles and news stories, document groundbreaking neuroimaging techniques that reveal what happens in the brain while you are immersed in thought; the arrival of brain implants that alleviate mood disorders like depression; lab-made brains; psychological resilience; meditation; the intricacies of sleep; the new era for psychedelic drugs and artificial intelligence and growing insights leading to an understanding of our conscious selves. Before taking over the neuroscience beat, Stix, as Scientific American's special projects editor, oversaw the magazine's annual single-topic special issues, conceiving of and producing issues on Einstein, Darwin, climate change, nanotechnology and the nature of time. The issue he edited on time won a National Magazine Award. Besides mind and brain coverage, Stix has edited or written cover stories on Wall Street quants, building the world's tallest building, Olympic training methods, molecular electronics, what makes us human and the things you should and should not eat. Stix started a monthly column, Working Knowledge, that gave the reader a peek at the design and function of common technologies, from polygraph machines to Velcro. It eventually became the magazine's Graphic Science column. He also initiated a column on patents and intellectual property and another on the genesis of the ingenious ideas underlying new technologies in fields like electronics and biotechnology. Stix is the author with his wife, Miriam Lacob, of a technology primer called Who Gives a Gigabyte: A Survival Guide to the Technologically Perplexed (John Wiley & Sons, 1999).
