At Massachusetts Institute of Technology, Christopher Love and colleagues are working to find out whether energy from trees can be used to prevent forest fires. A sensor system taps into trees as a self-sustaining power supply. Each sensor is equipped with a battery that can be slowly recharged using electricity generated by the tree. The system produces enough electricity to allow the temperature and humidity sensors to wirelessly transmit signals four times a day, or immediately if there's a fire. Each signal hops from one sensor to another, until it reaches an existing weather station that beams the data by satellite to a forestry command center. The project is called EWAN; Early Wildfire Alert Network.

Should men be able to give birth to children?
Lisa Mandemaker: Using an artificial womb could lead to more equality between sexes, but also between different family layouts. If men would be able to give birth to children, it would maybe be easier for male same-sex couples to have a child together.Join us!
