It's the end of another week, which means this roundup of HowStuffWorks' latest and greatest podcasts and articles is right on time! Keep reading for the scoop on mandatory gluten-filled wafers at the Vatican and Amazonian frogs with see-through skin.
In a dramatic show of trend-bucking (OK — it's really just religious adherence), the Vatican sent a statement to Catholic bishops banning communion wafers made of any flour other than wheat flour. That means folks who are gluten-sensitive must find an alternative, which fortunately does exist.

If you shoot a gun in the air, gravity's going to affect that stray bullet just like any other object on Earth. But how high can it go? And how lethal is it? BrainStuff host Christian Sager answers these questions and offers other, less potentially deadly ways to celebrate in a new episode of the podcast.
As the terrible headaches and profuse sweat that accompany fevers weren't already bad enough, fever dreams add insult to injury. Hosts Josh and Chuck get to the bottom of these nightmares in a recent episode of Stuff You Should Know.
When somebody tells you they can "see right through you," they're probably speaking metaphorically. But a new species of glass frog, the teeny-tiny Hyalinobatrachium yaku, is truly transparent — you can even see its beating heart. Read about the Amazonian amphibian here.

Hugh Dryden was NASA's first deputy administrator. But even before NASA was created, his engineering and leadership played a major role in the U.S. aeronautics development.

Crappy battery life is huge turnoff in smartphone specs — we need our phones to be on to show off their impressive array of powerful features. And all batteries eventually die, anyway.
