New Harvard tool helps fact-check cancer claims

The internet is full of warnings about things that cause cancer. Watch out for antiperspirants, scented candles, and bras, dubious web sites or sensational posts on social media warn. Steer clear of disposable chopsticks, microwaves, radon gas, and more. Scary or misleading claims are so plentiful that it’s hard to know which ones to take […]

Concussion care for children and teens: What parents need to know

Concussions are very common — in fact, they are the most common kind of traumatic brain injury (TBI). While most people recover completely, concussions sometimes lead to lifelong problems, as we’ve learned from the experiences of former National Football League players.

Save the trees, prevent the sneeze

When I worked at Greenpeace for five years before I attended medical school, a popular slogan was, “Think globally, act locally.” As I write this blog about climate change and hay fever, I wonder if wiping off my computer that I’ve just sneezed all over due to my seasonal allergies counts as abiding by this […]

How to break a bad habit

We all have habits we’d like to get rid of, and every night we give ourselves the same pep talk: I’ll go to bed earlier. I will resist that cookie. I will stop biting my nails. And then tomorrow comes, we cave, and feel worse than bad. We feel defeated and guilty because we know […]

Even low-level air pollution may harm health

A new scientific report supports research suggesting that even low levels of pollution — well below the current national regulatory cutoffs — may harm our health. Outdoor air pollution stems largely from the burning of fossil fuels (coal, gas, oil), which generate noxious gases, smog, and soot. Smog, which makes air look hazy, is created […]

Poor housing harms health in American Indian and Alaska Native communities

Robbed of ancestral lands, American Indian and Alaska Native tribal communities face an unparalleled housing crisis that pleads for national housing reforms.

New treatment approved for late-stage prostate cancer

In late March, the FDA approved a new therapy for advanced prostate cancer that is metastasizing, or spreading, in the body. Called Pluvicto (and also lutetium-177-PSMA-617), and delivered by intravenous infusion, the treatment can seek out and destroy tumors that are still too small to see with conventional types of medical imaging. Pluvicto is approved […]
