New treatments for deadly snake bites, and a fusion company that wants to get in the medical isotopes game Jul 18, 2024

Show notes

First up this week, Staff Writer Adrian Cho talks with host Sarah Crespi about a fusion company that isn’t aiming for net energy. Instead, it’s looking to sell off the high-energy neutrons from its fusion reactors for different purposes, such as imaging machine parts and generating medical isotopes. In the long run, the company hopes to use money from these neutron-based enterprises for bigger, more energetic reactors that may someday make fusion energy.

Next, we hear from Tian Du, a Ph.D. candidate in the Dr John and Anne Chong Lab for Functional Genomics at the University of Sydney. She talks about finding antivenom treatments by screening all the genes in the human genome. Her Science Translational Medicine paper focuses on a strong candidate for treating spitting cobra bites, but the technique may prove useful for many other venomous animal bites and stings, from jellyfish to spiders.

Targeting crop pests with RNA, the legacy of temporary streams, and the future of money Jun 27, 2024

Show notes

Guest host Meagan Cantwell talks to Staff Writer Erik Stokstad about a new weapon against crop-destroying beetles. By making pesticides using RNA, farmers can target pests and their close relatives, leaving other creatures unharmed.

Next, freelance producer Katherine Irving talks to hydrologist Craig Brinkerhoff about a recent analysis of ephemeral streams—which are only around temporarily—throughout the United States. Despite their fleeting presence, Brinkerhoff and his colleagues found these streams play a major role in keeping rivers flowing and clean. Brinkerhoff is currently a postdoctoral fellow at Yale University, and completed this work as a Ph.D. student at the University of Massachusetts Amherst.

Finally, the next segment in our books series on a future to look forward to. Books host Angela Saini talks with author Rachel O’Dwyer about her recent book Tokens: The Future of Money in the Age of the Platform. They’ll discuss new and old ideas of currency, and what it means to have our identities tied to our money as we move toward a more cashless society.

How dogs’ health reflects our own, and what ancient DNA can reveal about human sacrifice Jun 13, 2024

Show notes

On this week’s show: Companion animals such as dogs occupy the same environment we do, which can make them good sentinels for human health, and DNA gives clues to ancient Maya rituals and malaria’s global spread

Contributing Correspondent Andrew Curry joins host Sarah Crespi to discuss two very different studies that used DNA to dig into our past. One study reveals details of child sacrifices in an ancient Maya city. The other story is on the surprising historical reach of malaria, from Belgium to the Himalayas to South America.

Next on the show, using our canine companions to track human health. Courtney Sexton, a postdoctoral research fellow in the Department of Population Health Sciences at the Virginia-Maryland College of Veterinary Medicine, talks about what we can learn from these furry friends that tend to be exposed to many of the same things we are such as pesticides and cleaning chemicals.

Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Jackie Oberst, associate editor of custom publishing, interviews professors Miriam Merad and Brian Brown about the evolution of immunology in health care.

Putting mysterious cellular structures to use, and when brown fat started to warm us up Jun 06, 2024

Show notes

Despite not having a known function, cellular “vaults” are on the verge of being harnessed for all kinds of applications, and looking at the evolution of brown fat into a heat-generating organ

First on this week’s show, Managing News Editor John Travis joins host Sarah Crespi to discuss mysterious cellular complexes called “vaults.” First discovered in the 1980s, scientists have yet to uncover the function of these large, common, hollow structures. But now some researchers are looking to use vaults to deliver cancer drugs and viruses for gene therapy.

Next, what can we learn about the evolution of brown fat from opossums? Unlike white fat, which stores energy in many mammals, brown fat cells use ATP to generate heat, helping babies maintain their body temperature and hibernators kick-start their summers. Susanne Keipert, a researcher in the Department of Molecular Biosciences at Stockholm University’s Wenner-Gren Institute, talks about when in evolutionary history brown fat took on this job of burning energy.

Finally, this week we are launching our music refresh! If you are interested in what happened to our music—where it came from and how it’s different (and the same)—stay tuned for a chat with artist Nguyên Khôi Nguyễn.

Restoring sight to blind kids, making babies without a womb, and challenging the benefits of clinical trials May 30, 2024

Show notes

Studying color vision in with children who gain sight later in life, joining a cancer trial doesn’t improve survival odds, and the first in our books series this year

First on this week’s show, Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to discuss the pros and cons of participating in clinical trials. Her story challenges the common thinking that participating in a trial is beneficial—even in the placebo group—for cancer patients.

Next, Lukas Vogelsang, a postdoctoral fellow in the department of brain and cognitive sciences at the Massachusetts Institute of Technology, talks about research into color vision with “late-sighted” kids. Studying children who were born blind and then later gained vision gave researchers new insights into how vision develops in babies and may even help train computers to see better.

Last up on the show is the first in our series of books podcasts on a future to look forward to. Books host Angela Saini talks with author Claire Horn, a researcher based at Dalhousie University’s Health Justice Institute. They discuss the implications of growing babies from fertilized egg to newborn infant—completely outside the body—and Horn’s book Eve: The Disobedient Future of Birth.
