Due to the coronavirus pandemic, the Science Weekly podcast will now explore some of the crucial scientific questions about Covid-19. Led by its usual hosts Ian Sample, Hannah Devlin and Nicola Davis, as well as the Guardian's health editor Sarah Boseley, we’ll be taking questions – some sent by you – to experts on the frontline of the global outbreak.

As restrictions in England are due to relax on 17 May 17, new coronavirus variants first detected in India are spreading across the UK. Public Health England designated one, known as B.1.617.2, as a ‘variant of concern’ last week. It is now the second most common variant in the country. Anand Jagatia speaks to The Guardian’s science correspondent, Nicola Davis, and Prof Ravi Gupta about what we know and how concerned we should be
Prompted by an illness that took her to the brink of death and back, Jemma Wadham recalls 25 years of expeditions around the globe. Speaking to the professor about her new book, Ice Rivers, Shivani Dave uncovers the importance of glaciers – and what they should mean to us
When The Guardian began reporting on the climate crisis 70 years ago, people were worried that warmer temperatures would make it harder to complain about the weather. Today it is the biggest challenge humanity has ever faced...
On 22 June 1918, the Manchester Guardian reported that a flu epidemic was moving through the British Isles. It was noted to be ‘by any means a common form of influenza’. Eventually, it took the lives of more than 50 million people around the world. In a special episode to mark the Guardian’s 200th anniversary, Nicola Davis looks back on the 1918 flu pandemic and how it was reported at the time...
Over her career, first as a forester and then as a professor of forest ecology, Suzanne Simard has been uncovering the hidden fungal networks that connect trees and allow them to send signals and share resources. Speaking to Suzanne about her new book, Finding the Mother Tree, Linda Geddes discovers how these underground webs allow plants to cooperate and communicate with each other
Worldwide, we drink around 2bn cups of coffee every day. But as coffee plants come under pressure from the climate crisis, sustaining this habit will be increasingly challenging. Recently, a new study provided a glimmer of hope: a climate-resistant coffee plant just as tasty as arabica. Patrick Greenfield asks Dr Aaron Davis about his work tracking it down, and speaks to Dr Matthew Reynolds about developing climate-resistant crops
In the second of two episodes exploring our biological clocks, Linda Geddes speaks to Prof Till Roenneberg about how social restrictions during the pandemic have altered our sleep patterns and whether maintaining these changes could reduce social jetlag
Do you like to get up and go as the sun rises, or do you prefer the quiet hush of the late evening? Many of us tend to see ourselves as being ‘morning larks’ or ‘night owls’, naturally falling into an early or late sleep schedule. These are known as our ‘chronotypes’. Studies have shown that those with later chronotypes are at risk of a range of negative health outcomes, from an increased likelihood of developing type 2 diabetes to depression...
Why do we scream? Whilst past research has largely focused on using screams to signal danger and scare predators, humans scream in a much wider range of contexts – from crying out in pleasure to shrieking with grief. Madeleine Finlay speaks to Prof Sascha Frühholz about his new study identifying what emotions humans communicate through screams, and how our brains react differently to distinct types of scream calls
After mounting concern over reports of rare but serious blood clots in a small number of recipients of the Oxford/AstraZeneca vaccine, last week the UK’s Joint Committee on Vaccination and Immunisation (JCVI) recommended that healthy adults under 30 should have an alternative jab if they can. To find out what’s behind the change in advice, Nicola Davis speaks to Dr Sue Pavord about what this rare clotting syndrome is, and asks Prof Adam Finn about how the JCVI made its decision
