Cross Section: Sir Venki Ramakrishnan – Science Weekly podcast
Nicola Davis sits down with Nobel prize-winning scientist Sir Venki Ramakrishnan to discuss the competition he faced in the race to discover the ribosome – AKA the gene machine. Is competition good for science, or would a collaborative approach be better?
What role should the public play in science? - Science Weekly podcast
There are concerns that a science journal may revise a paper amid pressure from activists. What role should the public play and should science have boundaries to protect its integrity? Ian Sample presents. Since publishing, we received complaints. We value this feedback and we would like to highlight: The intention…
Falling fertility: lessons learned from Botswana – Science Weekly podcast
Fifty years ago, the average woman in Botswana had seven children. Now she will have fewer than three. Enabling women to control their fertility has had huge ramifications for their health, education and employment – could President Trump’s ‘ global gag rule’ threaten this? Nicola Davis travels to Botswana to…
Mars is barred: why we shouldn't go to the red planet – Science Weekly podcast
Elon Musk believes we should colonise Mars to ensure the survival of the human race. But is this reasoning compelling enough? Hannah Devlin ponders the case against setting our sites on Mars
A step in the right direction: could implants help people walk again? – Science Weekly podcast
Four people with paraplegia were recently implanted with electrodes in their lower backs. They all regained movement below their injuries, and two walked again. This week Nicola Davis investigates this technique – epidural stimulation – and other approaches for treating spinal cord injuries
The weight is over: will kilograms get an upgrade? – Science Weekly podcast
On 16 November, scientists vote on whether to update the way we measure the kilogram. This week, Ian Sample investigates the history of the metric system, and finds out how universal constants might now make it more robust
Cross section: Mark Miodownik – Science Weekly podcast
What can a materials scientist learn from artists? How do you make robotic trousers? And what should we do about plastics? Hannah Devlin sits down with Mark Miodownik to find out
Opioid addiction: can the UK curb the looming crisis? – Science Weekly podcast
The US has been in the grip of an ‘opioid epidemic’ since the 1990s, and now a rise in opioid prescriptions and deaths is being seen across the pond. Ian Sample investigates and asks: what can we do the curb the looming crisis?
Are fungi the secret to a sweet sounding violin? – Science Weekly podcast
From making violins sound beautiful, to beer and bread, to creating life-saving medicine, fungi have an array of very useful attributes. This week, a report demonstrates just how little we know about this kingdom of life and what we are set to gain if we tap into fungi as a…
Could a new force of nature reveal the universe's dark side? – Science Weekly podcast
We can see only 4% of the observable universe – the rest is made up of invisible ‘dark matter’ and ‘dark energy’. Now scientists are looking for a postulated force of nature that could open a door to the dark side. Ian Sample investigates
Conservation: there will (not) be blood - Science Weekly podcast
Invasive species have been blamed for wiping out native populations. Conservationists face a hard choice: should they kill one species to save another? The answer is often yes. Nicola Davis explores this dilemma and asks whether there’s a more compassionate approach
Huntington's disease: the price paid for our big brains? – Science Weekly podcast
This degenerative illness has a few genetic quirks which scientists believe could cause secondary health benefits. Emerging research suggests that people with Huntington’s are less sickly, don’t get cancer as often and even have more brain cells. Hannah Devlin investigates.
Heatwaves: the next silent killer? - Science Weekly podcast
Heatwaves have ravaged much of the northern hemisphere, causing wildfires, destruction and death. Some are blaming heat stress for an increase in chronic kidney disease in Central America. Graihagh Jackson investigates the causes and health effects of heatwaves
Tricky taxonomy: the problems with naming new species – Science Weekly podcast
Species are hard to define, as they don’t fit neatly into the categories that science wants to put them into. But increasingly, people are naming new species without enough evidence to suggest they are indeed a separate taxon. Graihagh Jackson investigates why so-called taxonomic vandalism is on the rise and…
In vitro fertilisation: 40 years on – Science Weekly podcast
This week, the world’s first IVF baby turned 40. The procedure has come a long way since 1978, and more than 6 million IVF babies have now been born. But should we be concerned about the rising numbers of fertility treatments? And are we becoming less fertile? Hannah Devlin investigates
The dark side of happiness – Science Weekly podcast
Happiness means something different to all of us, be it contentment, pleasure or joy. But could pursuing it leave us sad instead? Nicola Davis explores the science and psychology of happiness
From Ebola to Nipah: are we ready for the next epidemic? – Science Weekly podcast
The 2014 Ebola outbreak killed over 10,000 people before it was eventually brought under control. As new infectious diseases appear around the world, what can we learn from past outbreaks to better prepare ourselves?
