While most animals swim using a tail or fluke, sea lions clap their fore flippers into their bodies to propel themselves to incredible speeds. It’s an elegant, efficient movement that land-dweller Megan Leftwich, an associate professor of mechanical engineering at George Washington University, wants to reproduce in robotic form.

We’re all guilty of constantly staring at a variety of screens throughout the day. The only problem is that the blue light that’s emitted by most electronics — and even energy-efficient lightbulbs — is notoriously bad for our eyes and, subsequently, our health. Here are three glasses that offer superior protection for your eyes both […]
From OneDrive to Slack, there are numerous ways to store files online. Because many platforms offer a certain amount of free storage, it makes sense to mix and match.
