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.

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.

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.
