From Technology.org:

To stay warm when temperatures drop outside, we heat our indoor spaces — even when no one is in them. But scientists have now developed a novel nanowire coating for clothes that can both generate heat and trap the heat from our bodies better than regular clothes. They report on their technology, which could help us reduce our reliance on conventional energy sources, in the ACS journal Nano Letters.

At the heart of this new clock is the element strontium. Inside a small chamber, the strontium atoms are suspended in a lattice of crisscrossing laser beams. Researchers then give them a little ping, like ringing a bell. The strontium vibrates at an incredibly fast frequency. It’s a natural atomic metronome ticking out teeny, teeny fractions of a second.

NASA is looking for ways to reduce the cost of sending humans to Mars. Their study explores dramatically cutting the cost of a human expedition to Mars by putting the astronauts into a deep sleep called “torpor” that would use existing medical procedures to reduce astronauts’ metabolic functions. Torpor can also occur naturally in cases of hypothermia.

Blended with intravenous feeding, a crew could be in a state of hibernation for the transit to Mars, which at best would be 180 days each-way.
