A new study (published in PLOS Biology) investigated how bats make sharp turns in the air, particularly when they have to grab the ceiling. It turns out aerodynamics have very little to do with it - it’s all about inertia. Just as a figure skater clutches his arms to his chest to increase his speed, bats pull in their wings to help them make turns.
You can read all about it (and see more video) in this piece by my friend Nsikan Akpan over at PBS Newshour.
I guess you could say I dropped the base

Scientists in the University of Wisconsin-Madison have successfully grown functional vocal cord tissue in a laboratory - yes, vocal cords that work. This remarkable new tissue engineering technique could, someday, be used to restore the voices of patients who have certain voice disorders that are (at the present junctures) untreatable.

Congress Instructs NASA to Build a Space Habitat by 2018
Some of NASA’s successes in 2015 include finding liquid water on Mars and icy mountains on Pluto. In fact, the agency has been making so much waves that the US Congress has decided to give it a raise.
However, there’s a catch.

“Space Train” Concept Could Get Humans to Mars in Two Days, If Only It Would Work
Rosemary Johnson was a promising violinist and member of the Welsh National Opera Orchestra when she was involved in a devastating car crash 27 years ago. The accident left her in a coma for seven months, and the resulting brain damage has robbed her of most of her ability to talk and move.
But thanks to new software that reads people’s brain waves, Johnson has been able to compose music for the first time since 1988, and has had the chance to have it played to her in real time by a professional string quartet.
“It was really very moving,” Eduardo Miranda from the Interdisciplinary Centre for Computer Music Research at Plymouth University in the UK, told The Telegraph.
Kim Goodsell was running along a mountain trail when her left ankle began turning inward, unbidden. A few weeks later she started having trouble lifting her feet properly near the end of her runs, and her toes would scuff the ground. Her back started to ache, and then her joints too.
This was in 2002, and Kim, then 44 years old, was already an accomplished endurance athlete. She cycled, ran, climbed and skied through the Rockies for hours every day, and was a veteran of Ironman triathlons. She’d always been the strong one in her family. When she was four, she would let her teenage uncles stand on her stomach as a party trick. In high school, she was an accomplished gymnast and an ardent cyclist. By college, she was running the equivalent of a half marathon on most days. It wasn’t that she was much of a competitor, exactly – passing someone in a race felt more deflating than energising. Mostly Kim just wanted to be moving.
So when her limbs started glitching, she did what high-level athletes do, what she had always done: she pushed through. But in the summer of 2010, years of gradually worsening symptoms gave way to weeks of spectacular collapse. Kim was about to head to Lake Superior with her husband. They planned to camp, kayak, and disappear from the world for as long as they could catch enough fish to eat. But in the days before their scheduled departure, she could not grip a pen or a fork, much less a paddle. Instead of a lakeside tent, she found herself at the Mayo Clinic in Rochester, Minnesota.
