How do animals undergo metamorphosis, and why? – podcast
Metamorphosis – where a creature remodels itself between life stages – is one of the most astounding and bizarre feats of biology. It’s also surprisingly common. Why do animals bother undertaking this huge transformational change, and how do they rebuild their bodies from one form to another? Natalie Grover investigates…
Covid-19: training dogs to sniff out the virus
What does a disease smell like? Humans might not have the answer, but if they could talk, dogs might be able to tell us. Able to sniff out a range of cancers and even malaria, canines’ extraordinary noses are now being put to the test on Covid-19. Nicola Davis hears…

Do smart assistants need a feminist reboot? Part 2
According to a UN study published last year, smart assistants with female voices are often programmed with contrite and demure responses to verbal abuse or harassment, entrenching harmful gender biases. In the second of two episodes, Alex Hern takes a look at the sexualisation of female AI and robots, what…
Do smart assistants need a feminist reboot? Part 1
From Rosie the Robot in the 1960s animated sitcom The Jetsons to Siri and Alexa today, technologies that perform the roles of housekeeper and secretary are often presented as female. What does the gendering of these machines say about our expectations of who should be doing this kind of work?…
Covid-19: is it possible to predict how sick someone could get?

What does it mean to be alive? Paul Nurse on defining 'life'
Is it possible to define the biological, chemical and physical functions that separate cells, plants and even humans from inanimate objects? In his new book, Paul Nurse, Nobel prize winner and director of the Francis Crick Institute, addresses a question that has long plagued both philosophers and scientists – what…
Covid-19 ethics: should we deliberately infect volunteers in the name of science? Part 2
Teams around the world are hard at work developing Covid-19 vaccines. While any potential candidate will need to be tested on thousands of volunteers to prove its safety and efficacy, some scientists have argued that the race to the finish line could be sped up by human challenge trials —…
Covid-19 ethics: Should we deliberately infect volunteers in the name of science? (part 1)
Would you be willing to have a dose of Sars-CoV-2 sprayed up your nose for medical research? For thousands around the world, the answer is yes. Eager volunteers have already signed up to take part in human challenge trials, where participants would be deliberately infected with the virus in order…
Covid-19: what happens when flu season hits? (part 2)
As the northern hemisphere heads into autumn and winter, cold and flu are beginning to spread and more people find themselves with coughs, fevers and a runny nose.
