The U.S. Population Is Older Than It Has Ever Been
The median age in the United States reached a record high of 38.9 in 2022, according to data released Thursday by the Census Bureau. It’s a rapid rise. In 2000, the median age was 35, and in 1980, the median was 30. While many 38-year-old millennials may still feel young, that age is an unusually high median for the country. (Goldstein, 6/22)

Cooking With Gas May Be As Bad As Inhaling Secondhand Smoke
Cooking with gas-fired stoves can cause unsafe levels of toxics to accumulate inside homes, exposing people to roughly the same cancer risk as breathing secondhand cigarette smoke, according to a new study. Researchers from Stanford University and nonprofit PSE Healthy Energy tested gas and propane stoves in 87 homes across California and Colorado and found that every appliance produced a detectable amount of cancer-causing benzene — a chemical with no safe level of exposure.

Athletes Swear By Ketone Drinks. A New Study Says They Don’t Work
Many competitive athletes, especially cyclists and runners, swear by ketone drinks, a popular sports supplement that promises to improve athletic performance by packing many of the purported benefits of a low-carb, high-fat, ketogenic diet into a single beverage. ... But in a new study, the supplement didn’t amplify recreational cyclists’ racing speed and instead left them performing worse after swallowing the beverage than after a placebo. It also gave many of them gas. (Reynolds, 6/21)
