In 1991, U.S. sociologist Scott Feld wrote, “Your friends have more friends than you do.” Feld’s so-called friendship paradox states that the friends of any given person have more friends on average than the person themselves.

Boosting protein BCL6 could help GLP-1 users retain muscle while losing fat

About one in eight adults in the United States has tried or currently uses a GLP-1 medication, and a quarter of those users cite weight loss as their main goal.

Blood-brain barrier study reveals insights into neurological disease treatment

Scientists from the University of Liverpool and their global collaborators have highlighted the most effective treatments for neurological diseases by overcoming one of medicine’s most difficult challenges: the blood–brain barrier. Led by Dr. David Dickens, their findings offer new hope for patients with conditions including Alzheimer’s, and Parkinson’s disease, brain tumors, and epilepsy.
