Science can make blind mice see again and deaf mice hear — now scent-deprived mice can sniff their surroundings and smell for the first time, after a new gene therapy. It may be a while before this treatment percolates up to humans, but it’s a sign that gene therapy could restore smell in this rare but disorder.
New generations of bio-inspired robots will be more than just inspired by nature — they may use actual biological components. Bioengineers at MIT have genetically modified muscle cells to respond to light, which could be used to make easily controllable robot muscles that look and act like the animals on which they're based.
Recent research tells us that the sound of our voices betrays clues about our age, whether we’re menstruating (if we’re female), our sexual behavior and our physical strength. All of these factors, evolutionary psychologists say, are indicators of her reproductive potential.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
