Will storms like Eunice become the norm?

Science Weekly ·

2022/02/22

Over the past week, the UK has been hit with three storms: Dudley, Eunice and Franklin. With high winds and heavy rain, they have brought death and injury, caused extensive damage to trees and infrastructure and stopped transport across the country. Madeleine Finlay speaks to Dr Fredi Otto about how rare these weather events are, and whether the climate crisis could bring us more frequent and intense storms in the future.

Will Silicon Valley help us live to 200 and beyond?

Science Weekly ·

2022/02/17

While Benjamin Franklin’s famous quote about death and taxes remains true for most, the same might not be said for some of the world’s billionaires. And their efforts to extend life are under way. Most recently, a Silicon Valley start-up called Altos Labs signed up a dream team of scientists, including numerous Nobel laureates, with an aim to rejuvenate human cells. Ian Sample speaks to Prof Janet Lord about the science of ageing, extending our health as well as our lifespans, and how old we could

2022/02/15

Last week Boris Johnson announced that all Covid regulations in England, including the requirement to isolate after testing positive, were due to be abolished on 24 February. Whilst the Omicron variant has caused fewer hospitalisations and deaths than many predicted, some scientists say the changes may be going too far, too soon. Madeleine Finlay gets the Guardian science correspondent Hannah Devlin’s view on whether there’s scientific evidence backing up this decision and what the changes could

Why does Elon Musk want to read your mind?

Science Weekly ·

2022/02/10

A few weeks ago, Elon Musk’s company Neuralink posted a job advert recruiting for a ‘clinical trial director’ to run tests of their brain-computer interface technology in humans. Neuralink’s initial aim is to implant chips in the brain that would allow people with severe spinal cord injuries to walk again. But, Musk himself has said that he believes this technology could one day be used to digitally store and replay memories. Madeleine Finlay speaks to Prof Andrew Jackson about how brain-computer

2022/02/08

Late in November, the World Health Organization designated the Covid variant B.1.1.529, with its many mutations, as a variant of concern. Dubbed Omicron, within weeks it had rapidly spread across the globe and become the dominant variant. But not far behind has been its even more transmissible cousin, BA.2. Initially taking off in Denmark and India, BA.2 is now making headway in several countries around the world, including the US and UK. Ian Sample speaks to Prof Nick Loman about how worried we

Are we getting any closer to understanding long Covid?

Science Weekly ·

2022/02/03

Extreme fatigue, brain fog, sleep disturbances, chest pain and skin rashes. These are just a few of the on-going symptoms of long Covid, a disorder that can persist for many months after an initial Covid infection. With such a vast range of symptoms, and health organisations stretched to capacity by the acute stage of the disease, long Covid has continued to remain something of a mystery. But with numerous studies trying to understand what exactly people are suffering from, progress is being made

There have never been more products and services devoted to helping women through the menopause, from hormones and supplements to apps and even laser treatments. But is all this choice actually helpful? And what’s the evidence that any of them actually work? Madeleine Finlay speaks to the Guardian science correspondent Linda Geddes about the great menopause gold rush – and how women can get the help they need..

They may be one of the world’s favourite supplements but, according to a recent study, more than one in 10 fish oil capsules are rancid. Most of the oil comes from Peruvian anchovetas, a type of anchovy, which is also used to feed pigs, poultry and farmed fish. And despite catching more than 4m tonnes a year of Peruvian anchovetas to cater to the global demand, large industry players want to scale this up even further. Madeleine Finlay speaks to environment journalist Richa Syal about why so many

Are animals the future of human organ transplantation?

Earlier this month, in a medical first, surgeons from the University of Maryland transplanted a genetically altered pig heart into a living person. Doctors believed it was their only chance to save the life of David Bennett, a 57-year-old patient who was considered too ill for a human organ replacement. With hundreds of thousands of people worldwide in need of new organs, are animals set to be the future of transplantation? Ian Sample talks to bioethicist Prof Arthur Caplan about how the operation

Could the food we eat and the air we breathe be damaging our immune systems? The number of people with autoimmune diseases, from rheumatoid arthritis to type 1 diabetes, began to increase around 40 years ago in the west. Now, some are also emerging in countries that had never seen the diseases before. Ian Sample speaks to genetic scientist and consultant gastroenterologist James Lee about how this points to what western lifestyles might be doing to our health, and how genetics could reveal exactly

Last week, the tech CEO Elizabeth Holmes – once described as ‘the next Steve Jobs’ – was convicted of fraud, and could face decades in prison. Her now collapsed company, Theranos, promised to revolutionise medicine with a machine that could run hundreds of health tests on just a pinprick of blood. Those claims have since been exposed as false – but could they ever have been true? Madeleine Finlay speaks to the Guardian’s wealth correspondent, Rupert Neate, about Silicon Valley’s trial of the

2022/01/11

It’s been called the most important glacier in the world. The Thwaites glacier in Antarctica is the size of Florida, and contains enough water to raise sea levels by over half a metre. Over the past 30 years it has been melting at an increasing pace, and currently contributes 4% of annual global sea level rise. Ian Sample speaks to marine geophysicist Dr Rob Larter about a new research mission to the Thwaites glacier, the role of Boaty McBoatface and what it’s like to see a region melt away before

On Wednesday, 194,747 daily confirmed Covid cases were reported for the whole of the UK. But this doesn’t include all the people who have caught the virus for the second, or even third time. In fact, official figures for England, Scotland and Northern Ireland don’t include those who have had Covid before, despite warnings from scientists that up to 15% of Omicron cases could be reinfections. Madeleine Finlay speaks to the Guardian’s science editor Ian Sample about why reinfections are so high for

Science Weekly ·

2022/01/04

New year resolutions often include eating more healthily, doing exercise and trying to shift some of the extra weight put on over Christmas. Yet research suggests the vast majority of people who do lose weight ultimately end up putting nearly all of it back on. So why is it so difficult? Madeleine Finlay speaks to health journalist and ex-neuroscientist David Cox on the science of metabolism, and what it means for our health. Help support our independent journalism at <a

2021/12/30

From electrons behaving as both particles and waves to a cat in a box that’s both dead and alive, the consequences of quantum physics are decidedly weird. So strange, that over a century since its conception, scientists are still arguing about the best way to understand the theory. In the second of two episodes, Ian Sample sits down with the physicist Carlo Rovelli to discuss his ideas for explaining quantum physics, and how it affects our understanding of the world.

It has been more than a century since the groundwork of quantum physics was first formulated and yet the consequences of the theory still elude both scientists and philosophers. Why does light sometimes behave as a wave, and other times as a particle? Why does the outcome of an experiment apparently depend on whether the particles are being observed or not? In the first of two episodes, Ian Sample sits down with the physicist Carlo Rovelli to discuss the strange consequences of quantum theory and

Yesterday, daily cases in the UK exceeded 100,000 for the first time since the pandemic began. Despite this, the government has stuck to its guns in refusing to introduce any restrictions in England before Christmas Day. Yesterday also saw the publishing of a report from a team at Imperial College London that suggests, in the UK, the risk of a hospital stay is 40% lower with Omicron than Delta.

For three consecutive rainy seasons, the eastern Horn of Africa has experienced poor rainfall. Confounded by Covid-19 and desert locust invasions, millions are now facing starvation across parts of Kenya, Ethiopia and Somalia. Already, livestock and wildlife are dying of thirst and hunger in large numbers. And at the heart of it all is the worsening climate crisis. Madeleine Finlay asks climate researcher Chris Funk what’s causing these devastating weather patterns and speaks to Nairobi reporter
