By Daryl Austin In a newly published study, Stanford scientists reveal we don’t age gradually, as has been traditionally believed.

The molecular changes that occur during each period could explain seeming sudden signs of...
By Julian Nowogrodzki A newly devised ‘brain clock’ can determine whether a person’s brain is ageing faster than their chronological age would suggest. Brains age faster in women, countries with more inequality and Latin American countries, the clock indicates. “The way your brain ages, it’s not just about years. It’s about where you live, what...

By Kate Murphy “You’re not listening!” “Let me finish!” “That’s not what I said!” After “I love you,” these are among the most common refrains in close relationships. During my two years researching a book on listening, I learned something incredibly ironic about interpersonal communication: The closer we feel toward someone, the less likely we are...
By Dani Blum As summer approaches, many people with spring allergies are still suffering. And as new Covid variants circulate, experts say we may also soon see an uptick in cases. (Though wastewater data suggests that Covid cases are currently fairly low.) It can be tricky to distinguish between seasonal allergy symptoms, early signs of the coronavirus or just a...
By Mark Travers Cultural, religious and societal norms have long painted masturbation as a shameful or immoral act, leading many individuals to feel guilt or embarrassment about engaging in it.

In a letter recently published in Nature Human Behavior, scientists are advocating for the recognition and mitigation of another type of environmental pollution that poses equivalent personal and societal dangers: information overload. With the internet at our...
By Jennifer Abbasi A poor diet now outranks smoking as the leading cause of death globally and in the United States, according to the latest data.
