Not only has the mRNA covid vaccine saved 14 million lives, it may also help our bodies fight off cancer. A study of cancer patients undergoing immunotherapy treatment showed those who received an mRNA vaccine lived nearly twice as long - and this effect was discovered by accident. In a trial of cancer vaccines, Elias Sayour’s team at the University of Florida used standard mRNA vaccines as a control - they weren’t meant to do anything. Except they did - and the effect was huge. It’s still early days, but as we await more trial results, people are beginning to speculate how this might transform cancer treatment.

From deforestation to coal use, we’re not moving fast enough on anything. Hear from the authors of the report, who offer an important message of hope.

Why do birds sing the dawn chorus? Many theories exist - 11 in fact - but a new one has emerged, after scientists were studying zebra finches in the lab. Hear their conclusion while enjoying the serenity of birdsong, recorded at some of the RSPB’s nature reserves.
