Magic
The theorists who first created the mathematics that describe the behavior of the recently announced "invisibility cloak" have revealed a new analysis that may extend the current cloak's powers, enabling it to hide even actively radiating objects like a flashlight or cell phone.
Right now it is effective for a limited range of wavelengths, but I'm sure they are working on extending that . . . perhaps through some form of modulation. As for practical application, the downside is it will probably end up being employed (abused) in some military scenario. It will certainly revolutionize stealth technology . . .
"Scientists can in principle design molecular keypad locks that accept any number of different inputs, for more complex devices that respond, say, only to long sequences of light pulses."
That's very interesting . . . and lots of practical applications from cryptography to medicine. There also seems to be some application in genetics . . . a person could have a lock tailored to his or her particular genetic makeup.
"You're either with them or against them . . . or sometimes you're both."
It was only a matter of time before someone marketed this . . . .
