UNLV is among the universities around the country participating in a push by the Obama administration to demographically shore up the Affordable Care Act health insurance marketplace by signing up more young adults.

Summer colds are the worst.

You’re not sure how you caught one, but you did — and now you’d love to know where it came from. Or maybe that’s one of those medical mysteries, the kind that Mary Guinan, Ph.D., M.D. solved. In her new book “Adventures of a Female Medical Detective” (with Anne D. Mather), she takes you on some not-so-cold cases.

The last time KNPR caught up with Mary Guinan, it was in honor of World Aids Day, and we talked to her about her working with some of the first AIDS patients as a scientist with the Centers for Disease Control.

Researchers at the University of Nevada, Las Vegas say nearly one-third of the state's kindergarteners are overweight or obese.

Nearly a third of Nevada children are considered obese by the time they enter kindergarten, according to a recent UNLV report.

March 8 is International Women's Day - the perfect time to reflect on the progress women have made, and the challenges they face all over the world. Late last year, Hanna Rosin wrote the book, "The End of Men," but men still dominate politics and business. Sheryl Sandberg's new book challenges women to "Lean In" to their careers, because many young women hold themselves back at work. Do you think that's good advice? Or does it ignore the plight of most working women?

A report last week that more than half of samples of brand-name canned tuna contained more mercury than deemed safe by the U.S. Environmental Protection Agency (EPA) raised concern among tuna lovers everywhere.
