Harald Haas on making waves in light communication

The Life Scientific ·

2023/06/27

Imagine a world in which your laptop or mobile device accesses the internet, not via radio waves – or WiFi – as it does today but by using light instead: LiFi. Well, that world may not be as far away as you might think. In fact, the technology is already here; and it’s thanks in large part to the engineering ingenuity of Harald Haas, Distinguished Professor of Mobile Communications and Director of the Li-Fi Research and Development Centre at the University of Strathclyde.He tells Jim Al-Khalili

Anne Ferguson-Smith on unravelling epigenetics

The Life Scientific ·

2023/06/20

Our genes can tell us so much about us, from why we look the way we look, think the way we think, even what kind of diseases we might be likely to suffer from. But our genes aren't the whole story. There are other, complex and intriguing systems within every cell in our bodies which control which of our tens-of-thousands of genes are switched on, or off, in different parts of the body, and under different circumstances.Welcome to the fascinating world of 'epigenetics', which our guest, the molecular

The Life Scientific ·

2023/05/23

The world around us is three-dimensional. Yet, there are materials that can be regarded as two-dimensional. They are only one layer of atoms thick and have remarkable properties that are different from their three-dimensional counterparts. Sir Andre Geim created the first-ever man-made 2D material, by isolating graphene, and is one of the pioneers in this line of research. Even beyond his Nobel Prize-winning work on graphene, he has explored new ideas in many different areas of physics throughout

Julie Williams on Alzheimer’s disease

The Life Scientific ·

2023/03/28

There are almost a million people in the UK living with dementia, and Alzheimer’s is the most common form. But the disease actually starts long before any noticeable symptoms appear, and over the past decade, studies have shown that it is much more complex than previously thought. Julie Williams has been at the forefront of this effort, uncovering the genes that make us susceptible, and has transformed our understanding of this devastating disease. She has brought researchers together to create

The Life Scientific ·

2023/03/21

Since 1900, our best estimates suggest that earthquakes have caused around 2.3 million deaths worldwide; we saw the devastating effects of one just recently, in Turkey and Syria. And as scientists have been at pains to point out over the years, there is no reliable short-term warning system. But thanks to the work of people like James Jackson, an Emeritus Professor of Active Tectonics at the University of Cambridge, we are finding new ways of understanding and withstanding seismic activity.James

2023/03/14

Marie Johnston is a pioneer in the field of health psychology: the discipline that seeks to understand how psychological, behavioural and cultural factors contribute to our physical and mental health. Today an emeritus professor in health psychology at the University of Aberdeen, her career exploring behavioural interventions has shown that even the subtlest shift in how we act can dramatically change our behaviour and lives for the better – whether that’s in an individual recovering from a stroke,

2023/02/28

Jim Al-Khalili talks T cells, our immune response and Long Covid with Prof Danny Altmann. Danny Altmann joined ‘team T cells’ in his twenties and has been studying how these killer operate ever since. How do they know which cells to search and destroy? The T cell wing of our immune response is highly targeted and incredibly clever, on a par with the most sophisticated military intelligence operation and in recent decades there have been dramatic advances in our understanding of how it all works

2023/02/21

Jim Al-Khalili talks to astrophysicist Haley Gomez about defying expectations and becoming a world expert on cosmic dust.For centuries, cosmic dust was a major source of irritation to optical astronomers because, like smog, it stopped them from seeing the stars. Now studies of these tiny particles are challenging some deeply held assumptions about the physics of the universe. Haley’s research has changed the textbook explanation of how cosmic dust is formed and helped to open our eyes to just how

2023/02/07

How a once-derided approach to statistics paved the way for AI. Jim Al-Khalili talks to pioneering mathematician, Professor Sir Adrian Smith.Accused early in his career of ‘trying to destroy the processes of science’, Adrian went on to prove that a branch of statistics (invented by the Reverend Thomas Bayes in 1764) could be used by computers to analyse vast sets of data and to learn from that data. His mathematical proofs showed that Bayesian statistics could be applied to all sorts of real world

What use to science is a pesky organism that feeds on rotting fruit? Professor Bambos Kyriacou has spent fifty years observing the behaviour of fruit flies. He keeps them in the lab and in his garden in their thousands, has recorded fruit fly courtship songs using a microphone loved by Jonny Carson (because it made his voice sound deeper) and invented equipment to keep track of their sleeping patterns. He tells Jim Al-Khalili how fruit flies sparked his interest in genetics and how experiments with

Leon Barron monitors pollution in our rivers, keeping tabs on chemicals that could be harmful to the environment and to our health. He’s also gathered intelligence on the behaviour of millions of Londoners by studying the water we flush down the loo. His analysis of sewage revealed, for example, just how much cocaine is consumed in London every day. And he’s helped the Metropolitan Police to crack crimes in other ways too, inventing new chemistry tools that can be used by forensic scientists to
