Big, Beautiful Bird Brains
By Emily Willoughby @eawilloughby It is probably not a coincidence that the verbs ape and parrot have such a similar meaning: to imitate an observed behavior.

Brain Health: Fight Brain Age with Civic Activity
Have you had a “senior moment” today? Do you worry about the onset of Alzheimer’s disease, dementia, and other forms of brain atrophy in old age? These are common concerns. As we age, our brains can shrink, but a new study from John Hopkins University reveals that brain health can be improved with civic-minded activities such as volunteering and teaching. Our brains can do incredible things, such as control robotics such as this mind-controlled robotic arm, or learn to use other tools. Our brains are so amazing that we are even trying to…
