iOS: Navigating along roads is easy - just start up Google Maps or Waze - but finding your way on a trail in the woods tends to require a patchwork of PDFs, paper maps, and apps that only work for one park or system. Hikepack aims to change that.

Gorillas, the largest primates in the world, can stand up to 1.8m tall and weigh upwards of 180kg. They're normally very peaceful animals - more Koko and less King Kong - but a dominant silverback male has the strength of several men, and isn't afraid to use it to defend his troop.

Look at this freaking thing. It's all ballooning and sharp and you wouldn't want to run into it in a dark alley. This is just one of the amazing images that you can find on Nature Is F***ing Lit, one of the best subreddits I've ever stumbled on to.

It can feel nearly impossible to you access a sense of wonder in today's all-the-information-any-time-you-want-it environment, but the answer, I find, is often in the natural world. Whether it's feeling the strange cool breeze that arises during the totality of an eclipse, watching a thousand-strong starling murmuration swirl in the sky, or tasting fresh mango plucked from the tree in front of you, our sensory experience of Earth's pleasures -- even if we know exactly how and why they happen -- can reacquaint us with wonder.

If you've ever taken a walk to de-stress, you know the powerful effect getting outside can have on making you feel refreshed mentally, emotionally and physically. But if you live in a busy city, finding nature to help you recharge can be a challenge.

When you're over in the US, one of the best things to do is visit the famous national parks where you get to see the preserved natural wonders; each park offers unique views. Recently a former National Geographic photographer visited every national park and tabulated the ones most likely to take your breath away.

The weather is improving -- slowly -- and your urge to venture outside grows. Whether it's a huge national park or just a green space closer to home, here are some channels that will inspire you to get out and explore.

You’re drifting off to sleep when, suddenly, there’s a bump and a thump and an unearthly shriek. But never fear, if your home is making these noises you probably don’t have ghosts, but a family of common brushtail possums. Researchers have documented 18 different brushtail possum sounds. These include “grunting, growling, hissing, screeching, clicking and teeth-chattering calls, many of which would not be out of place on a horror movie soundtrack”.
