Palm readings.
Scientists are taking technology in common laboratory usage for more than 15 years and adapting it in ways that may, quite literally, bring the laboratory into the field. The technology is known as surface plasmon resonance (SPR), and a team of scientists has taken a sensing unit that was once the size of an old-fashioned console television and shrunken it down into a handheld unit no bigger than a conductor's baton.
