Holy Cow, Can You Hear Me Now?
Hearing loss has many causes including genetic disorders, extended exposure to dangerously loud sounds and normal aging. Hearing aids can’t repair the damage regardless of the cause. Taking a different approach that uses biology and technology, researchers at Princeton are developing a bionic ear that contains biological and electronic materials, including bovine or cow cells, silicone, and silver nanoparticles. The structure of cartilage cells from cows is similar to that of human cells, and bovine cells are much easier to obtain.
What Cows Can Teach Us About Autism
A team at Yale University analyzed the effects of a new oxytocin nasal spray on social functioning of autistic children. They reported that the medication facilitated social functioning. Other experiments using animal models have shown that the medication promotes social behavior and bonding. With a little help from a few run-of-the-mill dairy cows, the role of oxytocin in social behaviors and anxiety is now paving the way towards new treatments for autism.
