Weirdly flowing water finally has an explanation:'quantum friction '
How quantum friction explains water’s strange flows in carbon nanotubes, and the latest from the Nature Briefing.In this episode:00:53 A theory for water’s baffling behaviour in carbon nanotubesAt large scales, water flows faster through a wider pipe than a narrower one. However, in tiny carbon nanotubes flow-rate is flipped, with water moving faster through the narrowest channels. This week, researchers have come up with a new explanation for this phenomenon: quantum friction. If validated, it could allow material designers to fine-tune flows through tiny channels, which could be useful in processes such as water puri...

Coronapod: Why T cells have been overlooked
Much of the coverage of COVID immunity often focuses on antibody response and for good reason - these small, y-shaped proteins can detect, and in some cases neutralise, viruses like SARS-CoV-2. But as variants like Omicron evolve to evade antibodies, the role of another part of the immune system, T cells, has been brought into sharper focus. These immune cells work in a different way to antibodies, attacking infected cells rather than the virus itself, which can make their response broader and more robust. Now, research is showing that, unlike antibodies, T cell potency is not impacted by the mutations in variants like Omi...

Audio long read: Is precision public health the future — or a contradiction?
The burgeoning field of precision public health is a tech-centric approach that looks to target public-health interventions to the specific people who need them.Precision approaches are taking off and its advocates say this concept promises to save money and lives. However, other researchers are concerned that as funders provide huge amounts of money for precision-public-health initiatives, the focus will be taken away from conventional public health approaches that could improve the lives of millions.This is an audio version of our feature: Is precision public health the future — or a contradiction?

Coronapod: COVID death toll is likely millions more than official counts
As of January 2022, the WHO reports that 5.5 million people have lost their lives to the pandemic. However, many research groups suggests that this number is likely to be a significant underestimate, although it is hard to be certain as counting mortality across the world is an exceptionally difficult task. In this episode of Coronapod we ask why, and delve into the range of approaches scientists are taking to try to get to the bottom of the sticky problem - from excess death counts, to machine learning and even satellite imagery.News Feature: The pandemic’s true death toll: millions more than official cou...

Challenging the dogma of gene evolution, and how chiral nanoparticles could give vaccines a boost.In this episode:00:45 Genome mutations may be less random than previously thoughtA long-standing doctrine in evolution is that mutations can arise anywhere in a genome with equal probability. However, new research is challenging this idea of randomness, showing that mutations in the genome of the plant Arabidosis thaliana appear to happen less frequently in important regions of the genome.Research article: Munroe et al.News and Views: Important genomic regions mutate less often than do other regions13:45 Research Hig...

Podcast Extra: Recreating the lost sounds of spring
As our environments change, so too do the sounds they make — and this change in soundscape can effect us in a whole host of ways, from our wellbeing to the way we think about conservation. In this Podcast Extra we hear from one researcher, Simon Butler, who is combining citizen science data with technology to recreate soundscapes lost to the past. Butler hopes to better understand how soundscapes change in response to changes in the environment, and use this to look forward to the soundscapes of the future.Nature Communications: Bird population declines and species turnover are changing the acoustic properties of sp...
