There are less than 100 female black physicists in the United States. Morehouse professor Hadiyah Nicole-Green is one of those few women. And she's on the forefront of a new technology that uses lasers to target and destroy tumors. Professor Green has received a million dollar grant to push her research into clinical trials. She joins us to talk more about her medical breakthrough and why her fight against cancer is so personal.

Plus, a new microneedle patch designed by Georgia Tech could make it easier than ever for people to protect against measles. The tiny patch is administered with just the press of a thumb to the skin. Could this be a game changer for vaccines? We look back at our conversation with Georgia Tech’s Mark Prausnitz and Rebecca Martin, director of the CDC’s Global Immunization Division, about this new technology.

Babbling is exactly what it sounds like: indiscernible words of jumbled consonants and vowels strung together.

Gordon Ramsay, a doctor at the Marcus Autism Center in Atlanta, has collected the largest database of baby babbles. We revisit our conversation with Dr. Ramsay about how these recordings could help parents prevent a child from becoming nonverbal.
