Chilean mummies

2021/10/25

Think of ancient mummies, and you might imagine Egyptian pharaohs in their highly decorated cases. But in actual fact, Chile has the oldest mummies in the world. Unesco recently addded the archaeological sites and the artificial mummification of the Chinchorro culture to its World Heritage List. Around 300 mummies have been excavated from three different sites in the north of the country, near the border with Peru. The nomination took decades of work, drawing on many years of different scientific

Just how do we balance the growing demand for electricity worldwide with the need to reduce fossil fuel emissions to address climate change? In our second programme on the Earthshot prize Chhavi Sachdev looks at some of the solutions. From projects looking at providing green hydrogen to industry worldwide and remote communities, to village scale solar electricity networks in Bangladesh and a portable pay as you go powerpack in Nigeria.Also how to provide a livelihood for people who live in areas

While international meetings to discuss climate change and polices that affect the world can seem rather distant to us as individuals, on a local level there are many exciting and creative initiatives all over the world where people are developing practical solutions to the environmental problems they see. The Earthshot prize highlights many of these projects, ideas and initiatives which have the potential to make a difference locally and globally.In this three part series Chhavi Sachdev looks at

The Evidence: To boost or not to boost?

2021/10/02

The divide between the Covid vaccine haves and have-nots has been described as “criminal”, with only 20% of people in low and middle income countries having had one dose, compared with 80% in higher income countries. Countries with high vaccination rates have been called on to give up their place in the vaccine queue.The dual-track global vaccination programme has led to real anger, made worse by announcements of booster programmes in richer countries (despite the World Health Organisation calling

China's great science leap

Discovery ·

2021/09/27

President Xi Jinping is investing seriously into his strategic vision of turning China into a nation of scientific pace-setters. China’s past contributions to modern-science have been proportionally lacklustre, but with a reinvigorated focus over the past two decades, China is fast turning from imitator to innovator. What might this increasing scientific prowess mean for the future of China’s development as well for the international scientific community?Whereas once many Chinese scientists chose to

Future vaccines

2021/09/06

The COVID19 pandemic has revolutionised the way vaccines are made, and underlined the inequalities in access to vaccines. But will it leave a legacy? Roland Pease explores the potential for mRNA and other revolutionary vaccines to make future health protection faster, safer and more flexible, whether 'universal' vaccines will give broader protection, and how access to vaccines can be made more equitable.Picture: Coronavirus vaccines on the production line, Credit: MikeMareen/Getty Images

Tamsin Edwards on the uncertainty in climate science

2021/08/30

Certainty is comforting. Certainty is quick. But science is uncertain. And this is particularly true for people who are trying to understand climate change.Climate scientist, Tamsin Edwards tackles this uncertainty head on. She quantifies the uncertainty inherent in all climate change predictions to try and understand which of many possible storylines about the future of our planet are most likely to come true. How likely is it that the ice cliffs in Antarctica will collapse into the sea causing a

The Evidence: How will the pandemic end?

2021/08/29

When all restrictions are lifted in a highly vaccinated country, how manageable is the coronavirus? Both Israel and UK’s experiments to do just that, have raised new worries about raising the risk of new vaccine resistant variants. Claudia Hammond and her panel of global experts consider our ability to predict how and when variants of concern are most likely to arise and how long our repertoire of vaccines can remain effective in riding out increasingly infectious waves of the virus.Also in the

The Life Scientific: Professor Martin Sweeting

When Martin Sweeting was a student, he thought it would be fun to try to build a satellite using electronic components found in some of the earliest personal computers. An amateur radio ham and space enthusiast, he wanted to create a communications satellite that could be used to talk to people on the other side of the world. It was a team effort, he insists, with friends and family pitching in and a lot of the work being done on his kitchen table. Somehow he managed to persuade NASA to let his

When does a crowd of people become unsafe? How well will the football team Aston Villa do next season? When is it cost-effective to replace a kitchen? The answers may seem arbitrary but, to Nira Chamberlain, they lie in mathematics. You can use maths to model virtually anything.Dr Nira Chamberlain is President of the Institute of Mathematics and its Applications, and Principal Mathematical Modeller for the multinational engineering company SNC-Lavalin Atkins.He specialises in complex engineering and

Lost for words

Struggling to find words might be one of the first things we notice when someone develops dementia, while more advanced speech loss can make it really challenging to communicate with loved ones. And understanding what’s behind these changes may help us overcome communication barriers when caring for someone living with the condition.When Ebrahim developed Alzheimer’s Disease, for example, he’d been living in the UK for many years. Gradually his fluent English faded and he reverted to his mother

A sense of music

Discovery ·

2021/08/02

Music can make us feel happy and sad. It can compel us to move in time with it, or sing along to a melody. It taps into some integral sense of musicality that binds us together. But music is regimented, organised. That same 'sense' that lets us lean into Beethoven makes a bad note or a missed beat instantly recognisable. But does that same thing happen in the minds of animals? Can a monkey feel moved by Mozart? Will a bird bop to a beat?Do animals share our 'Sense of Music'?Charles Darwin himself

Whatever happened to those sniffer dogs who were seeking out any passengers infected with Covid-19 at Helsinki airport? And did plans to sample sewage to spot outbreaks early prove successful? This week on The Evidence, we have listeners’ questions about some of the clever ideas which were in the news early on in the pandemic but we haven’t heard about for a while. Trials of treatments like the cheap steroid dexamethasone proved successful – but what about the anti-parasite medication,

Dare to repair: The fight for the right to repair

2021/07/19

Many electronics manufacturers are making it harder for us, to fix our broken kit. There are claims that programmed obsolescence is alive and well, with mobile phone batteries designed to wear out after just 400 charges. They claim it's for safety or security reasons, but it pushes constant replacement and upgrades. But people are starting to fight back. Mark Miodownik talks to the fixers and repairers who are heading up the Right to Repair movement which is forcing governments to act, and making

Materials engineer Professor Mark Miodownik looks back to the start of the electronics revolution to find out why our electronic gadgets and household goods are less durable and harder to repair now. As he attempts to fix his digital clock radio, he reveals that the drive for cheaper stuff and advances in design and manufacturing have left us with a culture of throwaway technology and mountains of electronic waste.Image: Apron housewife at kitchen dish washer, Credit: George Marks/Getty
