In response to listeners who have expressed coronavirus fatigue in recent weeks, Marnie Chesterton brings us up to date on some of the best and brightest breaking science we might have missed, with BBC\\u2019s Non-Covid-19 Science Correspondent Jonathan Amos.

Inching back to pandemic news, Marnie investigates the fallout of the lockdown from a climate perspective. In many countries, citizens have been asked to stay at home and not to travel unless it\\u2019s strictly necessary. As a result, the hubbub of normal life has slowed to a trickle. What impact has this had on levels of carbon dioxide in the atmosphere? Corinne Le Qu\\xe9r\\xe9, the Royal Society Professor of Climate Change Science at the University of East Anglia, explains just how dramatically these emissions have been affected around the world.

And the chances that intelligent life exists on other planets. David Kipping, Assistant Professor of Astronomy at Columbia University in the US, has calculated the odds of both life and intelligent life existing if he were to re-run earth\\u2019s history.
