Pour a cool glass of water and drink it up: nice, refreshing hydration ... with a side of chemical pollution? PFAS, a class of thousands of man-made chemicals that have been around since the 1940s, are present in our drinking water, soil, food and air. And yes our bodies.
Last week, the Environmental Protection Agency warned that even tiny amounts of some of PFAS chemicals found in drinking water may pose risks.
So, how do we navigate a world filled with potentially harmful chemicals? Arlene Blum, a biophysical chemist who spends a lot of her time educating the public about PFAS, guides us through what they are, why they're a problem, and what you can do to lower your exposure risks.
Access to a safe abortion always varied depending where you live. Now that the Supreme Court has overturned Roe v. Wade, abortions are becoming more heavily restricted or almost completely illegal in many states.
This has implications for reproductive health well beyond abortion – including types of birth control, fertility treatments and treatments during pregnancy. Many people may have to rethink – or think more intentionally about – decisions they've long taken for granted.

A lot of logistics are going on behind the scenes to get this new low-dose formulation of Moderna and Pfizer's vaccines out so that little kids can finally get protected. Here's why it's been a tricky rollout and what to know about how to get in line for your kids,
There's a vast world around us that animals can perceive — but humans can't.
For example, it might seem that there's little to detect in a dark room, a bird in the room would be able to pick up on the magnetic field of the earth and would know which direction to fly if it was time to migrate. A dog would be sniffing out various odors that a human would not be able to smell. A rattlesnake would sense the infrared radiation of other creatures in the room.
"Each of these creatures, we could all be sharing exactly the same physical space and have a radically different experience of that space," science writer Ed Yong says.
