Rob Stein is a correspondent and senior editor on NPR's science desk.

An award-winning science journalist with more than 25 years of experience, Stein mostly covers health and medicine.

Earlier in his career, Stein spent about four years as an editor at NPR's science desk. Before that, he was a science reporter for United Press International (UPI) in Boston and the science editor of the international wire service in Washington.

Stein is a graduate of the University of Massachusetts, Amherst. He completed a journalism fellowship at the Harvard School of Public Health, a program in science and religion at the University of Cambridge, and a summer science writer's workshop at the Marine Biological Laboratory in Woods Hole, Mass.

Stein's work has been honored by many organizations, including the National Academy of Sciences, the American Association for the Advancement of Science and the Association of Health Care Journalists.

For 15 years, Carla Price and her husband's sex life was great. But then things began to change.

"Before, I would want to have sex," says Price, who is 50 and lives in central Missouri. "But over the years my sexual desire has just dwindled to nothing."

Price has no idea why. She's healthy. She's not really stressed out about anything. And she's still totally crazy about her husband.

"It's not that our relationship got boring," Price says. "Because it's actually the opposite — we became closer as we got older together."

When Barbara Marder was diagnosed with lung cancer three years ago, she had part of her right lung removed, went through a round of chemotherapy and tried to move on with her life.

"I had hoped that everything was fine — that I would not create difficulty for my children, that I would get to see my grandchildren grow up," says Marder, 73, of Arnold, Md.

But a routine scan a year later found bad news: The cancer was back — this time in her other lung.

AUDIE CORNISH, HOST:

Vapor produced by electronic cigarettes can contain a surprisingly high concentration of formaldehyde — a known carcinogen — researchers reported Wednesday.

The findings, described in a letter published in the New England Journal of Medicine, intensify concern about the safety of electronic cigarettes, which have become increasingly popular.

As expected, this year's flu vaccine looks like it's pretty much of a dud.

The vaccine only appears to cut the chances that someone will end up sick with the flu by 23 percent, according to the first estimate of the vaccine's effectiveness by the federal Centers for Disease Control and Prevention.

Two medical groups say doctors could replace the Pap smear with a different test to screen many women for cervical cancer.

But that recommendation, included in an "interim guidance" released Thursday, is highly controversial; other experts call it premature.

Wade Sweatt thought he had found a healthier way to get himself going in the morning. Instead of getting his daily jolt of caffeine from a cup of coffee or a Coke, Sweatt decided last summer to try mixing some powdered caffeine he'd bought via the Internet with some water or milk.

"Wade was very health-conscious, a very healthy person," says Sweatt's father, James. "His idea was, this was healthier than getting all the sugar and the sodium and ... artificial sweeteners from drinking Coca-Colas and diet Cokes."

E-readers may make it particularly hard to get a good night's sleep, according to research out this week.

A study that followed every nightly twitch, turn and snore of 12 volunteers for a couple weeks found that those who read from an iPad before hitting the sack had a harder time falling asleep, spent less time in a crucial phase of sleep, and were less alert the next day.

Federal health officials are investigating an incident involving the mishandling of the Ebola virus at the federal Centers for Disease Control and Prevention's headquarters in Atlanta.

The incident involved the material used in an experiment with the Ebola virus, the CDC said in a statement released late Wednesday. The material was accidentally moved from a high-security lab to a low-security lab on Monday. As a result, there's a possibility that one lab technician may have been exposed to the virus. That person will be monitored for 21 days for any symptoms.
