How Election Science Can Support Democracy
This week, the election season shifted into full gear with the Super Tuesday slate of primaries. But as the ballot options become more cemented, it’s not just pollsters and campaign operatives who are preparing for the elections—scientists are too.
The Union of Concerned Scientists has established what it calls an election science task force, looking at everything from ballot design to disinformation to voting security. Dr. Jennifer Jones, program director for the Center for Science and Democracy at the Union of Concerned Scientists, joins Ira to describe the goals of the effort in the weeks and months ahead.
The Genetic Roots Of Antibiotic Resistance
Antibiotic resistance—when pathogens no longer respond to the conventional antibiotic medications—is a serious medical problem. According to the CDC, over 2.8 million antibiotic-resistant infections occur in the U.S. each year, causing some 35,000 deaths. It’s in part due to overprescription of antibiotics in medicine, and the widespread use of antibiotics in animal agriculture. But the problem isn’t entirely of humans’ making. The roots of antibiotic resistance go back millions of years.
A recent study in the Proceedings of the National Academy of Sciences collected hundreds of soil and poop samples from around the world, to try to trace back the genetics of how resistance arose in Enterococcus, a genus of bacteria that live in the guts of pretty much every land animal. In the course of their analysis, the researchers identified 18 entirely new species in the genus Enterococcus, with over 1,000 genes that had never been seen before.
Dr. Michael Gilmore, the Chief Scientific Officer at Mass Eye and Ear, joins Ira to talk about the study and what the team hopes to learn about the causes of antibiotic resistance.
Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
