digg_url = ‘http://digg.com/general_sciences/Walkers_Swallow_RFID_Pills_For_Science’; It seems like some researchers from Radbound University in The Netherlands took advantage of the recent Four Days Marches of Nijmegen walking race for a little experiment earlier this month, where they convinced ten volunteers to swallow an RFID pill as part of a study to monitor body temperature. Apparently, the pills recorded and transmitted the walkers’ core temperature to a receiver in their backpack every ten seconds, which in turn sent the data via Bluetooth to a GPS-enabled phone that then relayed it to the operations center at Radbound. With all that info at their disposal, the researchers were able to monitor each walker and alert them if their temperature was reaching a dangerous level, or even alert others nearby if they weren’t responding (which apparently wasn’t necessary). As you might have guessed, the researchers are already hard at work planning an even larger test for next year’s event, which they hope could eventually lead to the system being used at marathons and other sports events.

Sure, Garmin’s new nüvi 500 series can get you from point A to point G on paved and well-lit highways, but that’s not the (whole) point here. Instead, these rugged (and waterproof) navigators are geared up to take to the trails, waterways and sidewalks with one-touch transitions between driving, bicycling, boating and walking modes. The 500 includes road maps and topographic maps for the lower 48 US states, Hawaii and Puerto Rico, while the 550 touts comprehensive street map coverage of the US and Canada. Both devices boast a 3.5-inch touchscreen, a removable, rechargeable battery, Garmin’s “Where Am I?” feature and geocaching support to boot. As for USers, you’ll find the 500 and 550 on sale in Q3 for $499.99, while those across the pond will see the nüvi 550 land this September for £299.
