Sleep apnea is a condition that affects millions of people, often without them even knowing it. It’s more than just loud snoring or restless nights. It can have serious health consequences.

Many women have, for decades, taken a drug called phenazopyridine to control pain from urinary tract infections. Sold under such brand names as Azo and Uristat, it’s available in most US pharmacies or groceries with a well-stocked health aisle and doesn’t require a prescription. Target Corp. and Walmart Inc. both offer their own generic versions. Given the ease of purchase, it’s a good bet many users assume the drug has been vetted by US regulators and found to be safe and effective. It hasn’t. In fact, the Food and Drug Administration 20 years ago raised questions about whether it truly works, as well as its potential to cause cancer. (Edney, 5/19)

Men are taller than women, by an average of about five inches. But why? It’s not a genetic inevitability — there are many species in the tree of life where females outclass males. A new study, published on Monday in the Proceedings of the National Academy of Sciences that involved genetic data from a million people, has found a partial explanation. (Kolata, 5/19)
