Researchers Develop a Test for Extreme Fatigue

Over centuries, the human body has developed a natural rhythm that uses biological and environmental factors to determine when to sleep and eat. But continued advances in technology—starting with the light bulb, all the way to on-demand entertainment—allow people to ignore these natural rhythms.

The Psychological Impacts of Gender-Affirming Hormone Therapy

According to the U.S. Census Bureau, about 2.6 million Americans identify as transgender, meaning their gender identity is different from the sex assigned to them at birth.

When transgender people seek medical therapy, they most commonly receive gender-affirming hormone therapy, which involves taking hormones to develop physical characteristics that better match their gender identity. Feminizing hormone therapy can trigger the development of breasts, help redistribute body fat to the hips and thighs, and lead to thinning of facial and body hair.
