A mussel-inspired glue for more sustainable sticking
In this episode:00:46 A sustainably-sourced, super-strong adhesiveThe modern world is held together by adhesives, but these fossil-fuel derived materials come at an environmental cost. To overcome this, a team have developed a soya-oil based adhesive, which also takes inspiration from the proteins that marine animals like mussels use to stick firmly to rocks. The researchers say their glue is strong, reversible, and less carbon intensive to produce than existing adhesives.Research article: Westerman et al.07:43 Research HighlightsWhy chemicals derived from wood could be sustainable alternatives to a common plastic building...

Sedentary Behavior and Dementia
There is an established link between sedentary behavior and cardiovascular disease, but the association between sedentary behavior and dementia is unclear. JAMA Deputy Editor Christopher C. Muth, MD, speaks with David A. Raichlen, PhD, University of Southern California, about a new study that investigates the relationship between sedentary behavior and dementia in older adults.

Our ancestors lost nearly 99% of their population, 900,000 years ago
In this episode:00:30 Early humans pushed to brink of extinctionAround 900,000 years ago the ancestors of modern humans were pushed to the brink of extinction, according to new research. Genetic studies suggest that the breeding population of our ancestors in Africa dropped to just 1,280 and didn’t expand again for another 117,000 years. This population crash would likely have had an impact on human genetic diversity, and may have driven the evolution of important features of modern humans, such as brain size.Nature News: Human ancestors nearly went extinct 900,000 years ago3:49 The pollution legacy of Antarctica’s res...

Psilocybin for Major Depressive Disorder
In a new study, psilocybin showed promise as a treatment for major depressive disorder (MDD). JAMA Associate Editor Donald C. Goff, MD, speaks with author Charles L. Raison, MD, from the Usona Institute, about the study, as well as Rachel Yehuda, PhD, Mount Sinai School of Medicine, who wrote an accompanying editorial about the potential benefits of psychedelic therapies.

SCCM Pod-489 The AIMS Trial: Battle of the Bundles, Hour-1 Versus 3-Hour
The Assessment of Implementation of Methods in Sepsis and Respiratory Failure (AIMS) Study seeks to determine the safest and most effective approach to sepsis intervention using the evidence-based Surviving Sepsis Campaign guidelines. Marylin N. Bulloch, PharmD, BCPS, FCCM, was joined by Mitchell M. Levy, MD, MCCM, at the 2023 Critical Care Congress to discuss the goal of the AIMS Study and the elements of both the Hour-1 and 3-Hour bundles. Dr. Levy is chief of the Division of Critical Care, Pulmonary, and Sleep Medicine and professor of medicine at the Warren Alpert Medical School of Brown University. He is also the medi...

Physicists finally observe strange isotope Oxygen 28 – raising fundamental questions
In this episode:00:47 First observation of oxygen 28Oxygen 28 is an isotope of oxygen with 20 neutrons and eight protons. This strange isotope has long been sought after by physicists, as its proposed unusual properties would allow them to put their theories of how atomic nuclei work to the test. Now, after decades of experiments physicists believe they have observed oxygen 28. The observations are at odds with theory predictions, so they imply that there’s a lot more physicists don’t know about the forces that hold atomic nuclei together.Research article: Kondo et al.News and Views: Heaviest oxygen isotope is found to...

Audio long read: Medicine is plagued by untrustworthy clinical trials. How many studies are faked or flawed?
Investigations suggest that, in some fields, at least one-quarter of clinical trials might be problematic or even entirely made up. Faked or unreliable trials are dangerous, as they could end up being included in the reviews that help inform clinical treatments. However, the extent of the problem in unclear, and many researchers urge stronger scrutiny.This is an audio version of our Feature: Medicine is plagued by untrustworthy clinical trials.

Fruit flies' ability to sense magnetic fields thrown into doubt
In this episode:00:49 The search for animals’ magnetic sense sufferers a potential setbackExactly how animals sense Earth’s magnetic field has long eluded researchers. To understand it, many have turned to the fly model Drosophila melanogaster, long thought to be able to detect magnetic fields. However, a recent Nature paper has raised questions about this ability, a finding that could have repercussions for scientists’ efforts to understand the mechanism behind magnetic sensing, one of the biggest questions in sensory biology.Research article: Bassetto et al.News & Views: Replication study casts doubt on magneti...

How welcome are refugees in Europe? A giant study has some answers
In this episode:00:46 A measure of refugees’ welcome in EuropeWith repeated humanitarian crises displacing millions of people, researchers have been considering how this might affect acceptance of refugees. Will some refugees be more welcome than others? Will continued movements erode support for refugees overall? To answer these questions, a huge study looks at the attitudes of 33,000 people from 15 European countries towards refugees. They find that overall support for refugees has slightly increased, although some characteristics, such as ability to speak the language of the country they’re settling in, are preferre...
