A Swedish start-up company is generating electricity from low-velocity tidal currents with a system of underwater kites called "Deep Green." The kites are equipped with turbines tethered to the ocean ...

Our solar system is speeding through the galaxy at more than three times the velocity scientists once believed, according to ...

According to NASA, its current speed is 153,545 mph (or 68.6 kilometers per second). But really, that just means super fast. It's nearly impossible to imagine something that fast when the fastest ...

Flume experiments were carried out to examine whether larval blackflies (Simulium ornatum complex, Diptera: Simuliidae) use microhabitats with a high-velocity current to reduce the risk of predation ...
