Canadian engineering team Aerovelo just broke their own world record in the Eta, a recumbent bicycle fitted with a windowless, egg-like shell. Most of the incredibly efficient machine is built of carbon fiber. The engine is muscle, sweat and sinew – engineer Todd Reichert.

I’ve covered Aerovelo’s efforts before: in 2012, they were racing to build a human powered helicopter. They succeeded in 2013.

Here’s a video I made about their competitors, a team of graduate students and undergrads from the University of Maryland.

though the great tit is a small bird that isn’t particularly threatening, scientists made a surprising discovery about them: during winter months with scarce food, great tits feed on bats. normally feeding on a diet of mostly insects with added fruits, seeds, and nuts, great tits who were unable to find sufficient food preyed on bats hibernating in rocky crevices within caves. when provided more common food by researchers, the behavior stopped.
