Just saw the Hobbit, holy shit. My mind is blown. I also forgot how amazing it is going to a midnight showing for such awesome movies. Smaug was so freaking bad ass. Ugh
About the only good thing that can be said about the budget deal just patched together by House Republican budget chair Paul Ryan and Senate Democratic budget chair Patty Murray is that the right-wing Heritage Foundation and the Koch brothers’ Americans for Prosperity oppose it.
But that doesn’t…
Exercise triggers the creation of highly excitable neurons in the hippocampus, the region of the brain associated with memory, learning, and emotional responses. This speeds up overall brain function, but because of the new neurons’ excitability, it should also make the brain more susceptible to anxiety. Yet it doesn’t.
To find out why, the Princeton team split lab mice into two groups. One group had access to a running wheel (with the mice averaging an impressive 2.5 miles per night), and the other did not. After six weeks, the researchers intentionally freaked out all the mice by dunking them in cold water, then looked at their brains with an fMRI machine. Almost immediately, they noticed that the two groups reacted differently. The brain cells of the inactive mice became agitated and leaped into a frenzy, while those of the active mice did not. The reason: the active mice were able to produce and release more of the neurotransmitter GABA, which helps sedate jumpy neurons.
The discovery … marked a breakthrough in understanding how exercise helps the brain regulate anxiety. In essence, exercise creates new, faster neurons, but it also reinforces the physiological mechanism that prevents those uppity brain cells from firing during times of stress.
Fascinating new research on how exercise and works as mental conditioning. For best results, pair exercise with sleep, which science has already indicated helps regulate our negative emotions. (via explore-blog)
Look at this solitudeofself we are becoming less anxious by becoming gym pros!

Leopard Seal tries to teach National Geographic photographer how to hunt.
Oh my god this is so adorable
“I think she thought the camera was my mouth, which is every photographer’s dream”
WARNING: includes a photo of a sort of mangled penguin so if you do not like looking at sort of mangled penguin be advised uwu
Oh my god, this big giant penguin-mauling seal got maternal on a photographer. This is like when your cat gives you “presents” on your doorstep because it thinks you’re a big manchild-cat who needs to learn how to feed yourself.
Except this is a wild animal and it doesn’t even know you you are. What a saint.
oh my god best ever
GETTING REAL TIRED OF YOUR SHIT HUMAN
Don’t forget how this awesomely large predator, known to attack and kill humans, protected this camera man by chasing off a young male that was coming up behind him.
