<h2>00:54 How Mammals’ mutation rates affects their lifespan</h2><p>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.</p><p><em>Research article: </em><a href="https://www.nature.com/articles/s41586-022-04618-z?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Cagan et al.</em></a></p><p><em>News and Views: </em><a href="https://www.nature.com/articles/d41586-022-00976-w?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Mutational clocks tick differently across species</em></a></p><h2></h2><h2>07:56 Research Highlights</h2><p>A clinical trial suggests a change to the treatment of a pregnancy ailment, and astronomers identify the largest known structure produced by a single galaxy.</p><p><em>Research Highlight: </em><a href="https://www.nature.com/articles/d41586-022-00981-z?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Ambitious trial inspires a rethink on a common ailment of pregnancy</em></a></p><p><em>Research Highlight: </em><a href="https://www.nature.com/articles/d41586-022-00980-0?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Even among ‘giant’ galaxies this one is record-setting</em></a></p><h2></h2><h2>10:43 The war in Ukraine’s effects on global energy</h2><p>Many European countries are dependent on Russian fossil fuels for energy production.

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.</p><p><em>News: </em><a href="https://www.nature.com/articles/d41586-022-01014-5?utm_source=naturepod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank"><em>Particle’s surprise mass threatens to upend the standard model</em></a></p><hr><p style='color:grey; font-size:0.75em;'> See <a style='color:grey;' target='_blank' rel='noopener noreferrer' href='https://acast.com/privacy'>acast.com/privacy</a> for privacy and opt-out information.</p>
