Science for the People

What makes breakfast, breakfast? Well, according to every movie and TV show we've ever seen, a big glass of orange juice is basically required. But our morning grapefruit might be in danger. Why? Citrus greening, a bacteria carried by a bug, has infected 90% of the citrus groves in Florida. It's coming for your OJ. We'll talk with University of Maryland plant virologist Anne Simon about ways to stop the citrus killer, and with science writer and journalist Maryn McKenna about why throwing antibiotics at the problem is probably not the solution.

When a new science finding is published about animal research, you might assume that scientists are trying to find out things that are useful for human health. They are, but it might not be so useful to all humans. Why? Because most biomedical research studies done in mice and rats are done only in male animals. Females were seen as too variable. The surging hormones, the emotions! The rodent show cravings, amirite? Well, not anymore. We're talking to Rebecca Shansky about why people should study males and females in research, and maybe stop worrying so much about mousey PMS. Related...

This week we take a look at the sociology of class. What factors create and impact class? How do we try and study it? How does class play out differently in different countries like the US and the UK? How does it impact the political system? We talk with Daniel Laurison, Assistant Professor of Sociology at Swarthmore College and coauthor of the book "The Class Ceiling: Why it Pays to be Privileged", about class and its impacts on people and our systems.

Our second annual Science Birthday is here, and this year we celebrate the wonderful Mary Golda Ross, born 9 August 1908. She died in 2008 at age 99, but left a lasting mark on the science of rocketry and space exploration as an early woman in engineering, and one of the first Native Americans in engineering. Join Rachelle and Bethany for this very special birthday minisode celebrating Mary and her achievements. Thanks to our Patreons who make this show possible! Read more about Mary G.

This week we're talking about earthquakes. If you live in Alberta or Oklahoma, you've probably heard about fracking or waste water wells causing earthquakes. We'll speak with seismologist Ruijia Wang about how that happens, and what we can control with these earthquakes. Then we speak to Sara McBride, with the United States Geological Survey, who explains why earthquake response communication should be taking embarrassment into account.

We only notice our immune systems when they aren't working properly, or when they're under attack. How does our immune system understand what bits of us are us, and what bits are invading germs and viruses? How different are human immune systems from the immune systems of other creatures? And is the immune system so often the target of sketchy medical advice? Those questions and more, this week in our conversation with author Idan Ben-Barak about his book "Why Aren't We Dead Yet?: The Survivor’s Guide to the Immune System".

At least some of you by now have probably spit into a tube and mailed it off to find out who your closest relatives are, where you might be from, and what terrible diseases might await you. But what exactly did you find out? And what did you give away? In this live panel at Awesome Con we bring in science writer Tina Saey to talk about all her DNA testing, and bioethicist Debra Mathews, to determine whether Tina should have done it at all.

This week, we take a look at 2 notable post world war 2 social psychology experiments and their creators: Stanley Milgram and his "shock machine", and Muzafer Sherif's boys camp study on group conflict. How did these scientists approach their work? How did the experiments run? How do the experiments hold up? How did people feel then about the ethics of them, and how do we feel now? We are joined by registered psychologist and author Gina Perry, who has written a book each on these men: "Behind the Shock Machine: The Untold Story of the Notorious Milgram Psychology Experiments",...

This week we're coming to you from Awesome Con in Washington, D.C. There, host Bethany Brookshire led a panel of three amazing guests to talk about the promise and perils of CRISPR, and what happens now that CRISPR babies have (maybe?) been born. Featuring science writer Tina Saey, molecular biologist Anne Simon, and bioethicist Alan Regenberg. A Nobel Prize winner argues banning CRISPR babies won’t work Geneticists push for a 5-year global ban on gene-edited babies A CRISPR spin-off causes unintended typos in DNA News of the first gene-edited babies ignited a firestorm The researcher who created CRISPR twins defends...

Summer is coming, and summer means sweat. Why do we sweat so much, and how do we do it? We hear from Yana Kamberov about the evolutionary origins of our sweat glands, and why it's one of the things that makes us mammals. Then we talk about why some (but not all) of our sweat STINKS. We'll speak with Gavin Thomas about the bacteria that give us our BO.
