With the death of biologist Mathilde Krim on Monday, at the age of 91 at her home in New York, the world lost a pioneering scientist, activist and fundraiser in AIDS research. She is being widely praised this week for her clarity, compassion and leadership.

Amid the panic, confusion and discrimination of the HIV epidemic's earliest days, Krim stood out — using science and straight talk, in the 1980s and beyond, to dispel fear, stigma, and misinformation among politicians and the public.

It's long been known that hormonal contraception, like any medicine, carries some risks. But doctors and women have hoped that the newer generations of low-dose contraceptive pills, IUDs and implants eliminated the breast cancer risk of earlier, higher-dose formulations.

Now a big study from Denmark suggests the elevated risk of getting breast cancer — while still very small for women in their teens, 20s and 30s – holds true for these low-dose methods, too.

New research published Monday adds fuel to an ongoing debate in the public health community over whether a few extra pounds are good, or bad, for you.

Earlier research found that being somewhat overweight, but not obese, may result in a longer life.

When Kathleen Muldoon had her second child everything was going smoothly. The delivery was short, the baby's APGAR score was good and he was a healthy weight.

"Everyone said he was amazing," says Muldoon.

So far, more than half of all U.S. states have legalized marijuana for medical use, and eight (plus the District of Columbia) have legalized the drug for recreational use. Varieties of cannabis available today are more potent than ever and come in many forms, including oils and leaves that can be vaped, and lots of edibles, from brownies and cookies to candies — even cannabis gummy bears.

We also have this this morning, if your child is taking medication of any kind, please be careful. A study in this month's journal, Pediatrics finds most parents get the medication dosage wrong most of the time. NPR's Patti Neighmond reports.

It really hit Terry White eight years ago when he was at the mall with his wife. He was out of breath every few minutes and had to sit down. "My wife told me I had to get to the gym and lose weight," he says.

He had dieted most of his life. "I've probably lost 1,000 pounds over the years," says White, a realtor in North Myrtle Beach, N.C. But he put most of it back on.

As men age, they lose testosterone — which some say affects their sense of well-being and sexual function. But for healthy older men, using supplemental testosterone as a remedy has been controversial. Past studies of the supplement's use have been relatively small, and the evidence about benefits and risks has been mixed.

Dr. Bob Sears, a pediatrician in Capistrano Beach, Calif., says that he strongly believes in the protective power of vaccines to save lives. But he's also well-known in Southern California as a doctor who won't pressure parents who refuse to vaccinate their children, or who refuse some vaccines, or who want to stray from the recommended schedule of vaccinations.

"They all come to me because, I guess, I'm more respectful of their decisions, more willing to listen to them," Sears says, "[and to] discuss pros and cons and acknowledge that there are some side effects to vaccines."

The symptoms of the flu are familiar: fever, chills, cough, congestion, feeling very, very tired. If you're a healthy adult under 65, you'll most likely recover in a week or two.

But for those older than 65, things can get worse fast, says Dr. H. Keipp Talbot, an infectious disease specialist at Vanderbilt University.

Until recently, freezing a woman's eggs was reserved mainly for young women facing infertility as a result of cancer treatments like chemotherapy.

But recent advances in technology have made freezing eggs easier and more successful, and likely have a lot to do with the recent decisions by Facebook and Apple to offer female employees a health benefit worth up to $20,000 to freeze their eggs.
