Are exhausts causing dementia?

Oxford Sparks Big Questions ·

2016/11/21

Many people are exposed to exhaust emissions every day in different ways. But what are the harmful effects of these fumes when we breathe them in? Could we see difficulties in other areas of our bodies? What is it doing to our brains? In our latest podcast we look at the tiny particles within these fumes to find out what they could be doing to our health. Teaming up with Oxford University of Earth Science and Lancaster University, we ask the question whether breathing in these fumes can lead to

2016/10/25

Statistician Dr Jennifer Rogers discusses the numbers linked to processed meat and bowel cancer. It hit the headlines last year that 'processed meat has been classified as a ‘definite’ cause of cancer', due to a report from The World Health Organization (WHO). But what really is the risk to your health if you eat a bacon sandwich? And are there other carcinogenic substances that have a higher risk than processed meat?

Dr Annette Fayet tells us about the Manx Shearwater; a little seabird that makes a huge journey. Every year they breed and raise their chicks in the UK before migrating to Argentina for winter, clocking up thousands of miles in their lifetimes. But what’s the price of parental devotion? Annette discusses how the harder parents have to works, the bigger the knock-on effects to their migration and breeding the following year are, and what this has to do with what’s going on in the oceans.

'Light' Part 3 - How does sunlight damage DNA?

Oxford Sparks Big Questions ·

2016/08/03

Once we've received our genetic make-up from our parents our genomes are stable, right? What causes mutations in our DNA as we live and grow, and how do our cells repair damage? We all know we should be careful when in the sun, but Prof Catherine Green's interests lie in understanding how Human cells manage to copy the enormous amounts of DNA they have without making mistakes and how they cope with threats; like sunlight. Cath describes what happens when DNA gets damaged and how her work seeks to

'Light' Part 2 - Harnessing a single photon

Oxford Sparks Big Questions ·

2016/07/27

What's the use of just one photon, the smallest bit of light? And what does it take to study it? We speak to Joelle Boutari about her work in quantum photonics where she's harnessing single photons, trying to understand their beheaviour better, all part of paving the way to better understand quantum features - the weird and unintuitive phenomena that you see at the smallest scales. Joelle describes her experiments and her hopes for the research.

Can we receive information through our lighting? Prof Dominic O'Brien explains how light might be the answer to adding more capacity to our wireless internet connections. You might be used to connecting to the internet through a wireless network that works through radiowaves, but what if we could use lights in buildings to send information; like data from the internet? Dominic describes where he's at with his work and where the challenges are.

Oxford Sparks Big Questions ·

2016/07/08

How can you spot what's happening in space billions of light years away from right here on Earth? Dr Garret Cotter works in the boundary of astronomy and high energy particle physics: gamma ray astronomy. Researchers use the Earth's atmosphere like a giant high energy particle detector to record particles that have travelled across space and reached Earth; not too dissimilar to the LHC, but thousands of times more energetic. By looking for tell-tale 'flashes' in the sky, researchers can actually

How do you train surgeons to do complex surgeries? How do you measure a trainee's progress? How can you accurately simulate the look and feel of surgery? Patrick Garfjeld Roberts is researching into simulation as a training method for surgeons doing keyhole surgery on joints. The aim is to be able to recreate the look and feel of keyhole surgery, where it's necessary to learn what's up and down all over again using their specialist instruments. Patrick discusses the progress that has been made in

'Senses' Part 1 - When the senses collide

Oxford Sparks Big Questions ·

2016/06/27

Can sounds change how things taste? How can we alter our experiences by taking advantage of how our senses mingle? From driving safety to gastronomic experiences, Prof Charles Spence discusses his groups work that focuses on the surprising effects seen when the senses 'talk to each other'. He describes how rather than being individual senses that never affect one another, stimulus of one sensory type can alter the perception of other sensory experiences. He describes how this has a multitude of

'Land, Sea and Air' Part 3 - What happens when we fly

Oxford Sparks Big Questions ·

2016/06/17

Oxygen levels are slightly lower when you fly on commercial airlines, so what effects does this have on people? Can it cause any problems? Dr Thomas Smith is both a researcher and a clinician with an interest in heart and lung function, specifically in relation to aviation. He describes what happens to the body when we fly and how the decreased pressure, equivalent to being 8,000ft up a mountain and equivalent lower oxygen levels, affects our bodies. This usually isn't a problem for healthy

What's in the deep ocean? And how can we study these remote and extreme ecosystems? And how is climate change affecting ocean ecosystems? Prof Alex Rogers explains his research in deep sea ocean hot spots, in some of the most remote and deepest parts of the ocean where there are still complex ecosystems to be found. He describes the challenges of working in extreme environments and how technology is essential for research. He also discusses the adverse effects that climate change is having on ocean

How can Chemistry take inspiration from nature to create cleaner and more efficient ways of producing and using Hydrogen as a source of clean energy? Professor Kylie Vincent explains how bacteria may hold the key to harnessing Hydrogen as a clean energy source: Chemists are looking to understand how bacteria make use of Hydrogen as efficiently as they do using common metals.

Can a little electrical stimulation help people learn quicker? And how would technology that does this be used? And why would you want to use this over medicines? Professor Roi Cohen Kadosh describes a phenomena that they've noticed where giving people a little electrical stimulation to the scalp appears to help people learn things quicker; and rather than using this to make super-geniuses, could this be used to help people with learning difficulties? Roi discusses how it might work, and discussed
