We sleep less as we age because our brains don’t think we’re tired

It’s a known fact that as we age, we sleep less. But the reasoning behind this phenomenon is poorly understood. Do older adults sleep less because they need less sleep, or because they simply can’t get the sleep they need?

Squid Communicate With a Secret, Skin-Powered Alphabet

Squid and their cephalopod brethren have been the inspiration for many a science fiction creature. Their slippery appendages, huge proportions, and inking abilities can be downright shudder-inducing.

In music, you have scales. In Jiu Jitsu, it’s drilling. Most of us just call it practice.

It’s continuing to practice your free throw even after you’ve nailed every shot. It’s playing through that song one more time even though you’ve made no mistakes. Scientists call this training past the point of improvement ‘overlearning.’ And a recent study in Nature Neuroscience suggests that it might improve performance by altering chemicals in the brain that “lock” in training.

LSD Can Mess With the Language Centers in Your Brain

The stereotype of late 1960s authors and musicians is that certain drugs can help to expand the mind and make the user more creative. As someone who has never taken psychedelics, I can’t know this for sure, but a recent study seems to be the first step in displaying scientific evidence in support of that claim.
