The partial shutdown of the U.S. government is approaching its third week, and it has caused a backlog for scientists employed or funded by the government. Scientists have had to leaving data collection and experiments in limbo. The Food and Drug Administration has had to suspend domestic food inspections of vegetables, seafood, and other foods that are at high risk for contamination. Journalist Lauren Morello, Americas bureau chief for Nature, puts the current shutdown in context to previous government stoppages. Morello also tells us how agencies and scientists are coping during this time and what we might see if the shutdown continues. And Science Friday producer Katie Feather reports back from the American Astronomical Society conference about how the shutdown has affected the meeting and the work of scientists. Last year, about 47,000 people in the United States died from an opioid overdose, including prescription and synthetic drugs like fentanyl, according to the CDC. And as the epidemic of opioid abuse continues, those looking to reduce death rates are searching for ways to keep drug users safer. But what if your smartphone could monitor your breathing, detect early signs of an overdose, and call for help in time to save […]
Science Friday, as heard on NPR, is a weekly discussion of the latest news in science, technology, health, and the environment hosted by Ira Flatow. Ira interviews scientists, authors, and policymakers, and listeners can call in and ask questions as well. Watch the latest science videos from the Science Friday website.
Every year in the dead of winter, bird lovers flock in large numbers to count as many birds as they possibly can on a single day. This is the Audubon Society’s annual Christmas Bird Count, a citizen science effort to track the trends of bird numbers over time. As the 2018 count comes to a close, Ira checks in with birders Jason Ward, Martha Harbison, and Laura Erickson about this year’s trends. Already many finches, including coveted grosbeaks, are showing up south of their normal winter range, much to the delight of avid birders from Florida to Vermont. The trio also share advice for beginning birders and making the most of the winter months, and which birds to look out for in 2019. As a bonus, Ira quizzes listeners on their bird call recognition skills. About the “Science Friday” Podcast
Every holiday season, tourists throng Rockefeller Center to see the famous tree, soaring above the paved plazas and fountains. But more than 200 years ago, they would have found avocado and fig trees there, along with kumquats, cotton, and wheat—all specimens belonging to the Elgin Botanic Garden, founded by physician and botanist David Hosack. Hosack grew up in the shadow of the American Revolution and became fascinated with the healing powers of plants as a young doctor studying abroad. Upon returning to the young United States, he founded America’s very first botanical garden, in the model of the great European gardens, as a place where he could study crops and medicinal plants. He was close friends with both Alexander Hamilton and Aaron Burr (he was the attending physician at their fatal duel) and went on to help found many of New York City’s civic institutions, such as Bellevue Hospital and the New York Historical Society, along with the first obstetrics hospital, mental hospital, school for the deaf, and natural history museum. “Hosack started with his garden, and ended with making New York New York,” says Victoria Johnson. She tells the story of Hosack’s life in her book American Eden: David […]
You’ve probably heard of the five second rule, when you drop a cookie on the floor and take a bite anyway because it’s only been a few seconds. What about when you’re at a party and you see someone double dip a chip in the salsa? How much bacteria does the double dip and the five-second rule spread around? Biologists Paul Dawson and Brian Sheldon investigate these questions their new book, Did You Just Eat That?: Two Scientists Explore Double-Dipping, the Five-Second Rule, and other Food Myths in the Lab. They talk about how bacteria spread around in our everyday lives and what can be done for food safe handling in our homes. What is the right age to get a flu vaccination at a pharmacy? In North Carolina, apparently, it’s 14. The age limit was written into state law a few years ago. Across the country, age limits for pharmacists to give vaccines range from 3 years old in some places to 18 in others. But why? Since the 1990s, states have been changing laws to allow pharmacists to give more and more vaccines to patients at younger ages. In 26 states and Washington D.C., pharmacists can give vaccines to people […]
For years, cancer treatment has largely involved one of three options—surgery, radiation, or chemotherapy. In recent years, however, a new treatment option, immunotherapy, has entered the playing field. It has become the first-line preferred treatment for certain cancers. Immunotherapy is a class of treatments that use some aspect of the body’s own immune response to help battle cancer cells. There are several different approaches, each with their own advantages and weaknesses.This year, the 2018 Nobel Prize in Physiology or Medicine was awarded jointly to James P. Allison and Tasuku Honjo “for their discovery of cancer therapy by inhibition of negative immune regulation.” The Nobel committee called their discoveries a landmark in our fight against cancer. Treatments based on their work are now in use against several forms of cancer, with many more trials underway. Still, the approach doesn’t work in all cases, and researchers are working to try to better understand why. How do raccoons keep getting into people’s trash? It might just be one of the greatest unsolved mysteries of our time. No matter what kind of fancy lid, bungee cord, or alarm system we use, somehow these masked creatures always find a way into our smelly garbage. But […]
