Science: Longer Lives And Slower Mutations, The Largest Galaxy Structure

For biologists, a long-standing question has been why some animals live longer than others. This week a team have attempted to answer this, by measuring the rates that different animal species accumulate mutations. They show that longer-lived animals acquire mutations at a slower rate, which helps to explain why cancer risk does not scale with lifespan.

10:43 The war in Ukraine’s effects on global energy

Many European countries are dependent on Russian fossil fuels for energy production. Following Russia’s unprovoked invasion of Ukraine, these countries are looking to wean themselves off these fuels, which could have short- and long-term impacts on emissions and food production.

19:58 A new measurement of a particle’s mass hints at new physics

Last week, a new estimate of the W boson’s mass caused much excitement among physicists. The result suggests that this particle is heavier than theory predicts, a finding that could be the first major breach in the standard model of particle physics. However, measuring W bosons is notoriously tricky, and further work will be needed to confirm the finding.

Science: New W Boson Particle Measurement, Marine RNA Viruses

On this week’s show: A new measurement of the W boson could challenge physicists’ standard model, and an abundance of marine RNA viruses.

Staff Writer Adrian Cho joins host Sarah Crespi to discuss a new threat to the standard model of particle physics—a heavier than expected measurement of a fundamental particle called the W boson. They chat about how this measurement was taken, and what it means if it is right.

Next, Sarah talks about the microscopic denizens of Earth’s oceans with Ahmed Zayed, a research scientist in the department of microbiology at Ohio State University, Columbus. They talk about findings from a global survey of marine RNA viruses. The results double the number of known RNA viruses, suggesting new classifications will be needed to categorize all this viral diversity.

Science: Probing Earth’s Inner Core, Complete Read Of Human Genome

On this week’s show: A journey to the center of the center of the Earth, and what was missing from the first human genome project.

Staff Writer Paul Voosen talks with host Sarah Crespi about the many mysteries surrounding the innermost part of our planet—from its surprisingly recent birth to whether it spins faster or slower than the rest of the planet.

Next, Sarah chats with Adam Phillippy about the results from the Telomere-to-Telomere (T2T) Consortium, an effort to create a complete and detailed read of the human genome. Phillippy, a senior investigator and head of the Genome Informatics Section at the National Human Genome Research Institute, explains what we can learn by topping up the human genome with roughly 200 more megabases of genetic information—practically a whole chromosome’s worth of additional sequencing.

Science: Navigating Life, Coastal Storminess, Boa Constrictors, Old Trees

Your ability to find your way may depend on where you grew up and how coastal storminess is changing.

00:47 Your ability to find your way may depend on where you grew up

Researchers have long been trying to understand why some humans are better at navigating than others. This week, researchers show that where someone grew up plays an important role in their ability to find their way; the more winding and disorganised the layouts of your childhood were, the better navigator you’ll be later in life.

11:39 How coastal storminess is changing

Coastal flooding causes billions of dollars in damage each year. Rising sea levels are known to be a key driver, but the importance of another factor, storm surges, is less clear. Typically after accounting for increasing sea level, they’re not thought to make much of an impact. However new research suggests that this may not be the case.
