According to the CDC, about one in four adults has a fear of needles. Many of those people say the phobia started when they were kids. For some people, the fear of needles is strong enough that they avoid getting important treatments, vaccines or tests. That poses a serious problem for public health. Researchers have helped develop a five step plan to help prevent what they call "needless pain" for kids getting injections or their blood drawn. Guest host Tom Dreisbach talks with Dr. Stefan Friedrichsdorf of UCSF Benioff Children's Hospitals, who works with a team to implement the plan at his own hospital. Friedrichsdorf told us some of the most important research on eliminating pain has come from researchers in Canada. Learn more about their work here. This episode was inspired by the reporting of our colleague April Dembosky, a journalist at member station KQED and KFF Health News. Read her digital story here.Got another question for a doctor?

Few humans have had the opportunity to see Earth from space, much less live in space. We got to talk to one of these lucky people — NASA astronaut Loral O'Hara. She will soon conclude her nearly seven month stay on the International Space Station. Transmitting from space to your ears, Loral talks to host Regina G. Barber about her dreams in microgravity, and her research on the ISS: 3D-printing human heart tissue, how the human brain and body adapt to microgravity, and how space changes the immune systems of plants.

Across the animal kingdom, menopause is something of an evolutionary blip. We humans are one of the few animals to experience it. But Sam Ellis, a researcher in animal behavior, argues that this isn't so surprising. "The best way to propagate your genes is to get as many offspring as possible into the next generation," says Ellis. "The best way to do that is almost always to reproduce your whole life." So how did menopause evolve? The answer may lie in whales. Ellis and his team at the University of Exeter recently published a study in the journal Nature that studies the evolution of menopause in the undersea animals most known for it. What they uncovered may even help explain menopause in humans. Curious about other animal behavior mysteries?
