Though a law requiring clinical trial results reporting has been on the books for decades, many researchers have been slow to comply. Now, 2 years after the law was sharpened with higher penalties for noncompliance, investigative correspondent Charles Piller took a look at the results. He talks with host Sarah Crespi about the investigation and a surprising lack of compliance and enforcement.
Also this week, Sarah talks with Brett Finlay, a microbiologist at the University Of British Columbia, Vancouver, about an Insight in this week’s issue that aims to connect the dots between noncommunicable diseases like heart disease, diabetes, and cancer and the microbes that live in our guts. Could these diseases actually spread through our microbiomes?
From a Genetic Engineering & Biotechnology News online article:
“We were able to show that if you can stop the plasmid from replicating, then most of the bacteria lose the plasmid as the bacteria grow and divide. This means that infections that might otherwise be hard to control, even with the most powerful antibiotics available, are more likely to be treatable with standard antibiotics.”
Researchers headed by a team at the University of Birmingham in the U.K. have developed a probiotic drink containing genetic elements that are designed to thwart antimicrobial resistance (AMR) in gut bacteria at the genetic level. The drink targets small DNA elements called plasmids that carry antibiotic resistance genes, and which are able to replicate independently and spread between bacteria. By preventing these plasmids from replicating, the antibiotic resistance genes are displaced, effectively resensitizing the bacteria to antibiotics.
This winter, NASA is sending a team of scientists, a host of ground instruments, and two research aircraft to study the inner workings of snow storms. The Investigation of Microphysics Precipitation for Atlantic Coast-Threatening Snowstorms, or IMPACTS, field campaign will be the first comprehensive study of East Coast snowstorms in 30 years.

Getting into an MRI machine can be a tight fit for just one person. Now, researchers interested in studying face-to-face interactions are attempting to squeeze a whole other person into the same tube, while taking functional MRI (fMRI) measurements. Staff Writer Kelly Servick joins host Sarah Crespi to talk about the kinds of questions simultaneous fMRIs might answer.
Also this week, Sarah talks with Igor Grossman, director of the Wisdom and Culture Lab at the University of Waterloo, about his group’s Science Advances paper on public perceptions of the difference between something being rational and something being reasonable.
The first of these urban amenities arose in the 1960s, but it was in the 1980s and ‘90s that the construction of science centers truly boomed. Inspired by historic World’s Fair exhibitions, industrial and natural history museums, and the sci-fi dreams of their early founders, science centers had a hands-on mission distinct from that of most museums—to engage rather than display. They offered levers you could pull, gyroscopes you could spin, lab experiments you could conduct.
The science center is an adolescent among museum types, one whose main growth spurt was in recent memory. Over the past 40 years, they went from a sparse to a ubiquitous presence, now found in almost every major city. Their emergence stretched the ontological essence of the museum: They present not objects, but concepts. Many science centers define themselves explicitly this way and possess slim to no permanent collections.
In this episode of the podcast, Nature reporter Davide Castelvecchi joins us to talk about the big science events to look out for in 2020. We’ll hear about multiple missions to Mars, a prototype electric car, efforts to prevent dengue, and more.
