While new statistics project increasing growth in the fields of science, technology, engineering, and math — so-called "STEM" subjects — in coming decades, girls and young women appear less academically engaged in those fields than their male counterparts. But why? Some experts say toys that parents buy for their children influence career choices later in life. Anush Avetisyan has more.
Scientists have been experimenting with four-legged robots for years, trying to see if they could be used as pack animals for carrying heavy loads over a difficult terrain. But the machine's power requirements limited their potential. That's changed, with a running robot designed by a group of engineers at Massachusetts Institute of Technology that operates on batteries rather than heavy gasoline-powered engines.
