4.5 out of 5 stars from 80 ratings
  • Excellent podcast

    These are really short, single-subject podcasts about 5-15 minutes long usually. They're always interesting.

  • Short, sharp science

    I really enjoy the concise summaries of recent findings. My only criticism is that they are infrequent (fortnightly) and each episode is very short!

  • Nice way to get updated

    Nice, short updates on some really cutting edge science. Nice interview with author. The disucssion is at a level where a lay person who does not know the branch of science being disucssed can actually understand....some of the topics are very cutting edge. Love it !!!

  • Real science

    PNAS Science Sessions is a great podcast because it’s scientists speaking about their own research, rather than reporters explaining it. And they focus on papers that appeared in PNAS, which is a great general science journal.

Talking Points

Recent interactions between the hosts and their guests.

AI in scholarly publishing
Q: What should editors and the scientific community take away from these findings?
There is a need for mandatory disclosure forms at submission and stronger investment in detection and verification to foster transparent, accountable use of AI in research.
AI in scholarly publishing
Q: How does AI disclosure compare to probable AI use in the literature?
Explicit disclosures are very rare (about 0.1% post-2023), while the estimated AI influence across papers is much higher, suggesting a gap between usage and disclosure.
AI in scholarly publishing
Q: Did journal policies affect AI usage by researchers?
The study found no statistically measurable effect of journal policies on the rate at which researchers use AI tools in writing; AI usage appears widespread regardless of policy status.
AI in scholarly publishing
Q: What policies have journals adopted to address generative AI in manuscripts?
Journal policies fall into four categories: strict prohibition, open policy, disclose required, and not mentioned; most journals fall into disclose required or not mentioned, with very few enforcing strict bans.
Genomic history of the Golden Horde
Q: What did you learn about the modern populations these elites were related to?
The study shows the Golden Horde samples are more closely related to Siberian and Northeast Asian populations than to modern Kazakhs, indicating deep regional genetic structure and historical population movements that shaped Central Eurasia.
