Batteries are a triumph of science—they allow smartphones and other technologies to exist without anchoring us to an infernal tangle of power cables. Yet even the best batteries will diminish daily, slowly losing capacity until they finally die. Why does this happen, and how do our batteries even store so much charge in the first place?

So it turns out that light from the very core of our Sun actually takes around 170 years (and 8 minutes) to reach Earth!
See why …

This is a marine ribbon worm. The weapon of the ribbon worm, or Nemertea, is a proboscis (elongated appendage) that the worm uses to snag and attach itself to its prey (sometimes with venom!). Basically, that proboscis is like a muscle inside of them that can dart out when the body contracts to attack prey.

Greg Gage is on a mission to make brain science accessible to all. In this fun, kind of creepy demo, the neuroscientist and TED Senior Fellow uses a simple, inexpensive DIY kit to take away the free will of an audience member. It’s not a parlor trick; it actually works. You have to see it to believe it.

Scientists have discovered a frog that changes its skin texture to match its surroundings.
The mutable rain frog can go from smooth (left) to spiny in minutes.
Pristimantis mutabilis, described in the Zoological Journal of the Linnean Society, is believed to be the first amphibian known to have this shape-shifting capability.
The scientists believe the ability to change skin texture to reflect its surroundings may enable Pristimantis mutabilis to help camouflage itself from birds and other predators. Learn more here, here or here.

When water in the atmosphere falls back down to Earth it is called precipitation. There are many different types of precipitation including rain, freezing rain, drizzle, snow, sleet, hail and even virga. Precipitation plays a major role in the water cycle – which can be grossly simplified as: water evaporates from earth and goes up into the atmosphere, then falls back to earth as precipitation.
Looks pretty cool from above too:
