Covid19 - should we test everybody ?

Epidemiologist Julian Peto is advocating mass testing as the key part of a plan to stop the virus spreading. Studies where everyone has been tested have picked up asymptomatic cases. With the addition of isolation and contact tracing this method of testing has been able to massively reduce the spread of the virus. The hope is such a coordinated scheme implemented nationally could help bring the numbers down.

There’s a question over which type of test is best to use for mass testing. At the moment many of us do lateral flow tests at home. Although they give instant results their accuracy has been shown to be strongly linked to how well the tests are conducted - hence the need to back up any positive findings with the more accurate PCR test. PCR takes longer and needs sophisticated lab equipment. However a compromise could be to use RT Lamp tests, they are accurate, give results in around 20 minutes, do require a very basic lab, but without the expensive equipment of PCR. A number of RT lamp tests have now been developed for SARS-Cov2. Kevin Fong has been to see the developers of one of them, the OxLAMP test.

And with the lifting of restrictions how are you going to judge your own personal risk from Covid? It’s a question that interests philosopher of science Eleanor Knox. She says government mandates on mask wearing and social distancing have allowed us to avoid tricky questions around our own potential risk from the virus and risks our own behaviour might pose to loved ones. Now there’s a lot more to think about in terms of balancing our desires to return to some semblance of normality while levels of Covid infection continue to rise.

One area that’s come into sharp focus over lockdown is exercise. Some people have been unable to exercise due to Covid restrictions while others have discovered a whole new interest in moving more. A new book ‘Move’ by Caroline Williams explores the links between brain function, evolution and movement. She says staying active is a fundamental part of what makes us human.

COP29: Are climate summits working?

COP29: Are climate summits working?

This year is set to be the world’s hottest on record, likely shattering the aspiration to limit global warming to 1.5C above pre-industrial levels. So where does this leave COP29, the upcoming UN climate conference in Azerbaijan? This week Inside Science is asking, are climate summits really working? What is the point of them - and are they doing enough? Joining Marnie Chesterton to discuss this are: - Joanna Depledge, expert on international climate negotiations at the University of Cambridge - Mark Maslin, climate change professor from University College London (UCL) - Jim Watson, professor of energy policy, also from UCL Presenter: Marnie Chesterton Producers: Ella Hubber, Sophie Ormiston & Gerry Holt Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth If you want to test your climate change knowledge, follow the links on this page to The Open University to take a quiz.

Whatever happened to graphene?

Whatever happened to graphene?

Twenty years ago this week two physicists at the University of Manchester published a ground-breaking paper describing the extraordinary qualities of graphene. The thinnest and strongest material known to exist – and better at carrying electricity than any metal – its discovery was hailed as revolutionary. But two decades on, it doesn’t seem to have changed the world, or if it has, it is doing so very quietly. So, what happened? We go on the trail of graphene, meeting Nobel Prize winner and Godfather of Graphene Andrew Geim, and learning what it has – and hasn’t – done and what might be next... Also this week, how to kill an asteroid and we talk the “other” COP with chief scientific adviser to the government, Dame Angela McLean.

Are our carbon sinks failing?

Are our carbon sinks failing?

The Earth’s natural carbon sinks absorb half of our pollution. But now, they appear to be collapsing. Why is this happening – and will we be able to reach our climate goals without them?Also this week, why a psychologist won the Nobel Prize in Physics, the culprit behind the second biggest mass extinction event, and does playing video games make you smarter?Presenter: Marnie Chesterton Producers: Sophie Ormiston, Ella Hubber, Anna Charalambou Editor: Martin Smith Production Co-ordinator: Andrew Rhys Lewis BBC Inside Science is produced in collaboration with the Open University.

Should we bring back extinct animals?

A woolly mammoth by 2028.That’s the bold claim from US company Colossal Biosciences, who say research is under way that will make this possible.But even if we have the technology to bring back a long dead species, should we? We hear the arguments for and against de-extinction.Also this week, what will Europa Clipper find when it heads to one of Jupiter’s icy moons and how to win a Nobel Prize.

Could coal shut-down mark new era for energy?

Could coal shut-down mark new era for energy?

“That’s the end of coal in the UK for electricity.” The UK’s last coal-fired power station has closed, ending Britain's 142-year reliance on coal. But what difference will the closure of Ratcliffe-on-Soar make – and could it mark a new dawn for clean energy? After 20 years of research into microplastics and headline upon headline on their potential harms, how much do we really know about these tiny particles? Also this week, Marnie turns lab rat for a navigation experiment, and why are we all so obsessed with Moo Deng?

How green is space travel?

How green is space travel?

The images beamed back to Earth of the first civilian spacewalk have prompted a very pertinent question from one Inside Science listener: What effect is space travel having on our climate? We're used to delving into the carbon footprint of Earth-bound travel – so this week we’re going to explore the impact of the rapidly growing space industry on our climate. How does a rocket launch compare to a flight taking off? Do we even know the true cost yet – and if it’s significant, what might the solution be? Also on the programme, a personal perspective from a remote island on worrying seabird declines, the results of a project to refreeze Arctic sea ice, and why new evidence unearthed about the Falkland Islands suggests it may once have looked very different...

Is lab-grown meat the future of food?

Is lab-grown meat the future of food?

Lab-grown meat, cultivated meat, cultured meat, in-vitro meat - whatever you call it, the industry claims it could be a game changer. Not just economically, but for feeding the planet in a sustainable way.But is it too good to be true? And will people even eat it? In this special episode of Inside Science, we take a deep-dive into lab-grown meat; visiting a production facility to see how it's made, hearing about the nuanced perspectives of British farmers, asking if this new industry can learn from the failings of GM foods, and trying to figure out what the true environmental costs of entirely new way of producing food really is.
