THE CHECK-IN

Start your morning with this dish, which features peppery arugula and radishes, a jammy egg, and omega 3-rich chia seeds. Swap in another cheese for feta if you prefer.

Perfluoroalkyl substances (PFAs) are harmful chemicals found in nonstick pans, cosmetics, and more. Now, a study in the Journal of Exposure Science and Environmental Epidemiology shows they’re in dental floss as well. In the study, researchers found that women who flossed with products that contain fluorine (a marker of PFAs) had higher levels of the chemicals in their blood than those who used other types. The results would likely hold for men as well.

The findings prove that PFAs migrate out of household products and into people’s bodies, says lead study author Katie Boronow, a staff scientist at the Silent Spring Institute in Newton, Massachusetts. Exposure has been linked to increased risk of cancer and other health problems, so it’s best to try to limit PFA risk when possible. If you use floss characterized as “easy glide,” chances are it contains these chemicals. Burden suggests you avoid any floss with descriptors like Teflon or PTFE (the scientific word for Teflon).

Research published in the journal Psychological Science found that the more accurate you are about someone’s unique characteristics, the less likely you are to be romantically interested in them. “This may be due to a more critical, evaluative mindset when on a first date,” says study author and Ph.D. student Lauren Gazzard. “If a romantic relationship is the goal, it might be a good idea to wear rose-colored glasses for the first few dates and to get to know the person a bit more before ruling them out.”
