Suspended Animation for Human Space Travel: Mice Study Shows Promise.

Scientists have successfully induced a torpor-like state in mice and rats using ultrasound waves targeting a precise part of their brains, bringing them closer to finding a way to induce suspended animation in humans. This technique could be used for space travel and medical purposes, particularly in life-threatening conditions such as stroke and heart attacks. The technology could make space travel more economical and safer, as astronauts would consume less food and water and be protected from the worst effects of exposure to cosmic radiation.
