DIY Nuke Detector

if your only source of news is the Daily Show or the occasional CNN bottom-of-screen headline crawl, you're probably aware that

  • terrorists want to kill you, your grandpa and quite possibly your little dog, too,
  • preferably with portable nuclear weapons, smuggled into the US via
  • our extremely vulnerable and barely-monitored shipping ports.

But not to worry: the DHS is on it. In July they announced a plan to equip our major ports with radiation scanners -- but it won't be ready until 2011, and it'll cost around $1.2 billion. According to Wired, the answer to our dirty nuke problems might be a little more home-grown:

"In San Francisco Bay, a group of do-it-yourself volunteer researchers is not waiting for the mushroom cloud. They say they are close to perfecting a portable device that could do much the same thing right now, for total out-of-pocket costs of about $12,000. The group, led by physicist and Sandia Lab weapons subcontractor Stanley Glaros, says it has already built a boat-mounted scanner with off-the-shelf parts that might reliably spot radiation spikes in container ships at sea from a kilometer away.

Encouraged, and armed with this background radiation survey to reduce false alarms, the team is now testing a homemade detector based on a 4-inch by 4-inch by 16-inch sodium iodide crystal ... the same technology used in many monitors currently deployed at ports around the country.
'The crystal is like Frodo's sword,' explained a Glaros collaborator. 'It starts to glow when the bad stuff's around, kind of a blue fluorescence.'"

See? Fight evil with crystals that glow blue. No need to get all billion-dollar-y.

A Simple Way to Charge Your iPhone in 5 Minutes

Spotting the “low battery” notification on your phone is usually followed by a frantic search for an outlet and further stress over the fact that you may not have time for a full charge. On iPhones, plugging your device into the wall for five minutes might result in only a modest increase of about three percent or so. But this tip from Business Insider Tech may allow you to squeeze out a little more juice.

The trick? Before charging, put your phone in Airplane Mode so that you reduce the number of energy-sucking tasks (signal searching, fielding incoming communications) your device will try and perform.

Next, take the cover off if you have one (the phone might be generating extra heat as a result). Finally, try to use an iPad adapter, which has demonstrated a faster rate of charging than the adapter that comes with your iPhone.

Do that and you’ll likely double your battery boost, from about three to six percent. It may not sound like much, but that little bit of extra juice might keep you connected until you’re able to plug it in for a full charge.

Trying to Save Money? Avoid Shopping on a Smartphone

Today, Americans do most of their shopping online—but as anyone who’s indulged in late-night retail therapy likely knows, this convenience often can come with an added cost. Trying to curb expenses, but don't want to swear off the convenience of ordering groceries in your PJs? New research shows that shopping on a desktop computer instead of a mobile phone may help you avoid making foolish purchases, according to Co. Design. Ying Zhu, a marketing professor at the University of British Columbia-Okanagan, recently led a study to measure how touchscreen technology affects consumer behavior. Published in the Journal of Retailing and Consumer Services, her research found that people are more likely to make more frivolous, impulsive purchases if they’re shopping on their phones than if they’re facing a computer monitor. Zhu, along with study co-author Jeffrey Meyer of Bowling Green State University, ran a series of lab experiments on student participants to observe how different electronic devices affected shoppers’ thinking styles and intentions. Their aim was to see if subjects' purchasing goals changed when it came to buying frivolous things, like chocolate or massages, or more practical things, like food or office supplies. In one experiment, participants were randomly assigned to use a desktop or a touchscreen. Then, they were presented with an offer to purchase either a frivolous item (a $50 restaurant certificate for $30) or a useful one (a $50 grocery certificate for $30). These subjects used a three-point scale to gauge how likely they were to purchase the offer, and they also evaluated how practical or frivolous each item was. (Participants rated the restaurant certificate to be more indulgent than the grocery certificate.) Sure enough, the researchers found that participants had "significantly higher" purchase intentions for hedonic (i.e. pleasurable) products when buying on touchscreens than on desktops, according to the study. On the flip side, participants had significantly higher purchase intentions for utilitarian (i.e. practical) products while using desktops instead of touchscreens. "The playful and fun nature of the touchscreen enhances consumers' favor of hedonic products; while the logical and functional nature of a desktop endorses the consumers' preference for utilitarian products," Zhu explains in a press release. The study also found that participants using touchscreen technology scored significantly higher on "experiential thinking" than subjects using desktop computers, whereas those with desktop computers demonstrated higher scores for rational thinking. “When you’re in an experiential thinking mode, [you crave] excitement, a different experience,” Zhu explained to Co. Design. “When you’re on the desktop, with all the work emails, that interface puts you into a rational thinking style. While you’re in a rational thinking style, when you assess a product, you’ll look for something with functionality and specific uses.” Zhu’s advice for consumers looking to conserve cash? Stow away the smartphone when you’re itching to splurge on a guilty pleasure. [h/t Fast Company]
