Hi everyone, Dr. Ali Mattu here. Recently the awesome people at D News invited
me to come over and make some science videos together! On TestTube Plus, Trace Dominguez and I explored
how to overcome anxiety. I partnered with D News’s Julia Wilde to
explain hair-pulling disorder. And I managed to squeeze in an episode on the psychology of sexting. Let me know what you think of the videos in
the comments below and be sure to subscribe to D News for more science videos every day
of the week.
