When today’s teenagers and young adults are struggling emotionally, some are turning not only to friends, family members and therapists but also to artificial intelligence.

A new study finds that flu shots were associated with moderate protection against the virus during the 2024-25 flu season.

Neuroscientist Miia Kivipelto’s life’s work has been about preventing dementia. Now, at 52, she has begun thinking more about her own vulnerability. “Midlife is the time,” said Kivipelto, a neuroscientist who recently joined the Yale School of Nursing as the inaugural director of its Center for Aging Well in New Haven, Connecticut. “It’s the last best chance to lower risk.” (Eunjung Cha, 6/11)

While isotretinoin (Accutane) is an incredibly effective acne medication, the intense side effects lead some patients to microdose the medication off-label. Isotretinoin is a very concentrated form of vitamin A that shrinks the sebaceous glands, reducing oil production, and is most often prescribed for acne, explained Raman Madan, MD, a dermatologist with Northwell Health in Glen Cove, New York, in an interview with MedPage Today in which a press person was also present.

On my second visit with Nancy Wexler at her Manhattan apartment, she had a gift for me. It was a copy of her newly published memoir, “My Life, My Science: Pursuing a Cure for Huntington’s Disease.” It had been signed with a stamp of her signature — she isn’t able to sign it herself. Nor could she rise from her brown faux-leather recliner to greet me — she can’t get up unassisted. Speaking requires effort. She can manage at most a few badly slurred words or phrases or, with great difficulty, a short sentence. (Kolata, 6/11)
