Just in case fixed sensors all across the country, bomb-sniffing bees, and Bay Area nuke detectors weren't enough to make you rest easy, Homeland Security is cookin' up another safeguard at the expense of privacy. Reportedly, the Department is looking into the idea of "outfitting cellphones with tiny, sensitive detectors that would alert the government and emergency responders to the presence of radiological isotopes, toxic chemicals, and deadly biological agents." Essentially, future mobiles could come pre-loaded with such a device that continuously monitors said chemicals and sends off alerts via GPS if anything goes awry. Of course, officials are expecting "quite a few hurdles" along the way, one of which will be battling the privacy advocates who don't understand that their handset probably already contains the technology for Big Brother to see everywhere they go. No word on when these plans could take effect, nor whether older phones will be retrofitted with the toxic sensors, but we can already envision quite a few false alarms care of the cellphone-totin' chemists in the crowd.

The folks at e-Fotografija have had enough of SDHC speed tests, and wanted to take things to the next level. After some extreme temperature tests (ranging from -30°C to +85°C) which seemed to do little to knock the cards out of commission -- though Kodak card did have to return to room temperature before restarting, while the industrial-grade ATP card kept right on humming -- the cards were blasted with Gamma radiation to really get the measure of the things. Sadly, no strange half-man, half-SD card creatures were created in the process, and in fact, high doses of radiation did absolutely nothing to impact the cards, meaning the relatively weak level of airport X-ray radiation should do nothing to your stash of pictures stored on these sturdy memory cards. Tune in next weak, when we'll find out if SD cards can pass through the core of the earth unscathed.

While homemade nuke detectors patrolling our waterways seems sufficiently plausible, remote-controlled rats searching for explosives is certainly pushing the bounds of acceptability, but to expect a swarm of "highly trained" bees to sniff out destructive material (without getting medieval on somebody) sounds like an awful lot of buzz. Nevertheless, an 18-month research study -- dubbed the Stealthy Insect Sensor Project -- at the US Energy Department's Los Alamos facility has just concluded, and team members have announced resounding success in teaching your average bee to "stick their proboscis (that tube they use to feed on nectar) out in the presence of explosives." The DHS sees potential in using the little buggers to "find dynamite and C-4 plastic explosives" as well as relatively dodgy "Howitzer propellant grains." Scientists have used a reward system to train the animals, by offering up a "sugar treat" each time they correctly signify explosive material, and suggest that teams of detectors (read: incensed bees) could be carried about in "portable containers about the size of a shoebox." While theoretically, this plan may seem sound, what happens when our enemies start covering their tracks in nectar -- or worse, when the insects unleash a painful revolt against our own brethren?

While being in the weapons distribution biz may seem a bit dodgy, an enterprising team in San Francisco is looking to prove their device is out to protect and serve (and save a lot of money). The Department of Homeland Security is looking to add safeguards to American ports by installing a series of radiation scanners designed to detect hidden nukes (and, we hope, dirty bombs) on incoming shipments. The problem is the $1.15 billion this project is supposed to cost, not to mention the five years it'll take to get it installed, so we're still pretty much exposed for awhile. Not one to take a (potential) threat lying down, physicist / Sandia Lab weapons subcontractor Stanley Glaros is manning a team which has already built a "boat-mounted radiation detection device from off-the-shelf components." The homebrew rad sniffer gives a visual alarm via a "sodium iodide crystal" that turns blue when danger is near (remember Frodo's sword?), but the mechanics behind the lighthearted signifier is no laughing matter. An Ortec Digibase photo-multiplier picks up signals over the air, which are collected into dynodes, and then run through a multichannel analyzer to identify radiological signatures. Regardless of the means, this nuke detector has been running "successfully" for eight months, and coming in at a cool $12,000 apiece, we're all for getting the job done on the cheap (and showing up the DHS in the process).
