As a life-long introvert, I was taken aback by the advice in the book Me, But Better , which was reviewed in your pages. Forcing yourself to conform to perceived societal expectations around sociability is a recipe for disaster in the long term. Accepting yourself, on the other hand, fosters self-compassion that brings long-term happiness …

If researcher Oswald Schmitz is correct about fish storing such large amounts of carbon, then we need to stop commercial fishing immediately. We know that world stocks of larger species have dipped to less than 10 per cent of what they were before industrial fishing took over. We could tackle the problem of excessive carbon …

I loved Menno Schilthuizen's take on the (relatively) new urban natural history discoveries to be made. Unfortunately, he falls into the trap of thinking that only urbanites are living in landscapes that are "completely different from natural habitats". The rural landscapes of Europe (especially the UK), North America and many other places are artificial too, …

Graham Lawton's article on the recovery of useful chemicals from sewage was excellent. I have long advocated for mainstream use of composting toilets – which can make use of our waste in situ – so it is helpful to put a value on the commodities we flush away ( 29 March, p 22 ). Extracting …

There is an alternative explanation other than extra education for the reduced incidence of dementia in UK adults born four years after the cut-off birth date for the 1972 increase in the school-leaving age, from 15 to 16, compared with those born four years prior ( 15 March, p 14 ). The older cohort were …

I read with interest your interview with Jaap de Roode on self-medication in animals. My research focuses on domestic livestock self-medicating against gut parasites using medicinal plants. De Roode mentions that farm animals lack a varied diet for better health. At Lincoln University's Integral Health Dairy Farm in New Zealand, we introduced woodland strips with …

Your review of Adam Kucharski's book Proof refers to "truth" and "truth-seeking" in science. I don't know if Kucharski's book uses these terms much, but perhaps it should be added that indisputable truth isn't available in science, and that seeking evidence for something is less important than seeking evidence against it. Nowhere is this better …

In their study on world population, the researchers used data from dam projects as the basis for their assertion that rural populations had been significantly underestimated. Could there be another explanation for the apparent discrepancies( 29 March, p 17 )? No doubt in many cases, people living in the area to be flooded were offered …

Reading "A wobbly start to radio astronomy on the moon" got me wondering: did NASA, in a spectacular case of nominative determinism, seal the lander's fate by naming the telescope mounted on it ROLSES-1? Perhaps someone should warn the agency not to use the name "Cosmic Radiation and Associated Solar Heating Interstellar Energy Sensor" (CRASHIES) …
