Don't like having to apply clunky heating pads every time you want to to deal with chronic muscle pain in your arms and legs? Eventually, you might not have to -- that therapeutic care could always be there. Korean researchers have developed a stretchable silver nanowire mesh that heats your joints no matter how you bend them. It's thin enough to fit under your clothes, runs on batteries and maintains a constant temperature, so you could wear the mesh whenever you're out instead of having to wait for prime opportunities to get relief.
There's no word on when this chainmail-like design will reach something you can buy, but there's talk of using it beyond medical purposes. You could use it to heat up a winter jacket, or provide efficient, evenly-distributed warmth in your car seat. If the technology pans out, you could feel better without having to let anyone know that you're feeling chilly or sore.
