Next time you take your temperature, maybe think twice about its accuracy. Despite what the mercury says, not all of your cells are really at 98.6 degrees, scientists reported in a new study. Using nanoscale thermometers, researchers have shown for the first time that living cells can exist at different temperatures. Busy sections are warmer, and less-active ones are cooler.
A reader inquires: “Why can’t we put people into some sort of cryogenic sleep and launch them to Mars—or to an even more distant destination, like Alpha Centauri?”

Setting aside very real concerns such as our lack of a spacecraft with suitable size and power to launch astronauts to Mars—much less the outer planets or other stars—suspended animation lingers more in the realm of sci-fi than reality. Yet the concept remains attractive, especially for longer journeys, because astronauts in a Rip Van Winkleâ€like stupor might be protected from the serious health hazards associated with distant space travel, and they wouldn’t need food—or entertainment.
