We have to admit that one of the promised uses of nanotech — ingestible machines that will be able to scrub arteries and repair organs — leaves us a little queasy.

It’s just that, well, let’s just say that we still remember “Innerspace,” and the idea Dennis Quaid zipping around our intestines is enough to make us wary of any mini-med devices. However, we’re willing to give the Jonah ingestible thermometer a try. The purple pill-shaped device is about the size of a very large vitamin, and can provide accurate body-temperature readings to a wireless receiver. Yeah, we’re still not that keen on swallowing machines. But in this case, it sounds preferable to getting our temperature taken the old-fashioned way.
