Back in the 1940s, '50s and '60s, doctors prescribed a hormone called diethylstilbestrol, or DES, to millions of pregnant women in the unfounded belief it would prevent miscarriages.

Smack in the middle of this period, the deformed thalidomide babies demonstrated the terrible things that can happen when drugs are casually prescribed during pregnancy.

Surprise In Your Sewage: Lots Of Exotic Viruses

Originally published on Wed October 12, 2011 10:03 am

You think your job is tough? Some scientists examined sewage from Pittsburgh, Barcelona and Addis Ababa in a hunt for unknown viruses.

They found scads. How many? At least 43,381.

To put that number into perspective, consider that up to now scientists have charted only about 3,000 viruses. And among the known viruses found in the sewage samples, only 17 were bugs that cause human disease — things like the common cold virus, diarrhea-causing Norwalk virus and human papilloma virus, or HPV, which causes cervical cancer and genital warts.

Working with grasshoppers, fruit flies, mice and human cells, the three scientists who won this year's Nobel Prize in Physiology or Medicine opened important windows on how all these creatures defend themselves against microbial invaders and refrain from attacking their own cells – except when they don't.

It's intricate and complicated stuff, but the two main concepts you need to know are: innate immunity and adaptive immunity.

Shortages Lead Doctors To Ration Critical Drugs

Laura Zakhar connects her son, Kevin, 15, to the "feedbag" that contains his nutrition. Lately, Zakhar has had trouble getting the calcium solution Kevin needs, in part because hospitals have been reserving limited supplies for patients who need it even more desperately than he does.
Elizabeth Larkin for NPR

Drug shortages mean a growing number of Americans aren't getting the medications they need. That's causing drug companies and doctors to ration available medications in some cases.

"We're now at 213 shortages for this year," says Erin Fox of the University of Utah, who tracks national drug shortages. "That surpasses last year's total of 211. And it doesn't seem like there's an end in sight."

Up to now doctors couldn't tell a man much about his chances of maintaining sexual function after surgery or radiation for prostate cancer.

"We'd say about half recovered or maintained their function," says Dr. Martin Sanda of Beth Israel Deaconess Medical Center in Boston. "And we'd be able to turn that up or down a little bit based on age."

HPV Vaccine: The Science Behind The Controversy

Experts disagree about whether girls as young as 11 should get the HPV vaccine.

The first vaccine against human papillomavirus, or HPV, which causes cervical cancer, came out five years ago. But now it's become a hot political topic, thanks to a Republican presidential debate in which candidate Michelle Bachmann inveighed against "innocent little 12-year-old girls" being "forced to have a government injection."

Behind the political fireworks is a quieter backlash against a public health strategy that's won powerful advocates in the medical and public health community.
