Japanese officials are preparing to distribute potassium iodide pills to people living near the nuclear power plants crippled by last week’s earthquake. Harvard Health Letter editor Peter Wehrwein explains what these pills do and who needs them.
The King’s Speech has won almost universal praise for its portrayal of reluctant monarch George VI’s stuttering. Harvard Health Letter editor Peter Wehrwein takes you behind the scenes with Alex Johnson, an expert in speech and stuttering at the MGH Institute of Health Professions in Boston; Caroline Bowen, an Australian speech-language therapist; and a few other scattered sources.
Tomorrow night at 6:30 p.m., tens of millions of television sets will be turned on as Americans sit down and participate in that unofficial national holiday called “watching the Super Bowl.” For many, it’s an excuse to see funny ads and the half-time show and to eat (how many of those spanking new Dietary Guidelines will be broken?), drink, and socialize. But […]
Does echinacea, the popular natural cold remedy, really work? It depends on what you mean by “work.” Results reported in today’s Annals of Internal Medicine found that echinacea may reduce the length of a weeklong cold by 7 to 10 hours and make symptoms a little less onerous. That can’t be characterized as a major effect, so many people may figure that […]
Perhaps as many as one in every 5 American adults will get a prescription for a painkiller this year, and many more will buy over-the-counter medicines without a prescription. These drugs can do wonders—getting rid of pain can seem like a miracle—but sometimes there’s a high price to be paid. Remember the heavily marketed COX-2 inhibitors? Rofecoxib, sold as Vioxx, […]
Vitamin D has been talked about as the vitamin — the one that might help fend off everything from cancer to heart disease to autoimmune disorders, if only we were to get enough of it. “Whoa!” is the message from a committee of experts assembled by the Institute of Medicine (IOM) to update recommendations for vitamin D (and for calcium).

Lung cancer is usually discovered late when it’s difficult to treat and has often spread outside the lung. A reliable screening test to find it at an earlier, more treatable stage would be a legitimate breakthrough—and could potentially save thousands of lives. About 160,000 Americans die each year from lung cancer, which is more than who die from breast, prostate, and […]
Trick or treat? It’s really a rhetorical question. They just want the Halloween candy. Millions of American children will get billions of sugar- and fat-laden treats on Sunday night in a tradition that has its roots in pagan and Christian rituals. It’s fun. The kids are outside, walking. And, gosh, they’re cute in their princess and pirate costumes. But nutritionally and dentally speaking, the […]
Embryonic stem cell research continues to be a political and legal hot potato that stirs up a lot of emotion and argument. In the meantime, researchers are making some remarkable progress using an alternative stem cell approach called induced pluripotent stem cells, or iPSCs (sometimes that gets shortened to iPS). An induced pluripotent stem cell is an adult cell, often a skin cell, […]
