Date rape drugs like Rohypnol and GHB have no odor or taste, they dissolve quickly in liquids and they don't linger in your system - in other words, they're very hard to trace. Which makes the new date rape drug sensor from researchers at Tel Aviv University such an interesting development.

When a ray of light comes into contact with a drugged drink, it is slightly altered The sensor can pick up that subtle change and sound an alarm - perhaps a beeping sound or a small flashing light, the researchers say. The sensor can operate with only 10 microlitres of liquid.

Early tests are very promising, but they're early tests - so in the meantime, you'll still need to keep an eye on your drink, just to be safe.
