I'm really stressed because I have a big deadline looming. I'd love to receive a simple treatment to help me, but there aren't any available.

When people and mice are anxious, brain cells release less of a neurotransmitter called serotonin. US scientists have identified the brain cells that control this decrease. The team were able to switch off these brain cells so the mice didn't get anxious in stressful situations.

That sounds really promising for treating mental problems... in mice. I hope some day it will be usable for humans. It definitely won't help me before my deadline!
