'Grow-and-prune' AI mimics brain development, slashes energy use

In a pair of papers published earlier this year, researchers showed how to start with a simple design for an AI network, grow the network by adding artificial neurons and connections, then prune away unused portions leaving a lean but highly effective final product. Growing and pruning results in software that requires a fraction of the computational power, and so uses far less energy, to make equally good predictions about the world. Constraining energy use is critical in getting this kind of advanced AI — called machine learning — onto small devices like phones and watches.

Boosting wind farmers, global winds reverse decades of slowing and pick up speed

In a boon to wind farms, average daily wind speeds are picking up across much of the globe after about 30 years of gradual slowing. Research led by a team at Princeton University shows that wind speeds in northern mid-latitude regions have increased by roughly 7% since 2010.
