Magnetism

MIT researchers have determined that the Earth’s geomagnetic field will not flip in the near future, reports Felicia Gans for The Boston Globe. While the intensity of the Earth’s geomagnetic field is decreasing, the current level is “double the planet’s average intensity over the past 5 million years.”

A system developed by Prof. Alfredo Alexander-Katz allows microscopic devices to navigate a cell’s surface, reports Alissa Zhu for Popular Science. “Doctors could use them to provide real-time updates on internal structures or distribute drugs to specific targets within a body.”
