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.

Are trees the answer to solving climate change?

Are trees the answer to solving climate change?

As a new warning is released by scientists that trying to offset our carbon emissions by planting trees alone won’t work, we investigate the role the Earth’s forests are playing in the fight against climate change.Marnie Chesterton is joined by Mark Maslin, Professor of Earth System Science at University College London, to help answer our top five questions about trees and CO2. We also speak to science writer and New York Times columnist Carl Zimmer about his new book ‘Air-Borne: The Hidden History of the Life We Breathe’, and what it tells us about what we’re breathing into our lungs each day. After we reported on the plight of some of our UK wild bird species earlier this year, many listeners got in touch wanting to know more about one species in particular: house sparrows. To look at why their numbers have been declining so sharply, and what we might be able to do about it, we hear from Imperial College London’s Dr Julia Schroeder, who has been studying the birds for 15 years.And Marnie is joined in the studio by Lizzie Gibney, Senior Reporter at Nature, to explore some of the fascinating research from around the world in this week’s science journals.Presenter: Marnie Chesterton Producers: Clare Salisbury, Dan Welsh and Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

What science is the UK government funding?

What science is the UK government funding?

How do you plan for the scientific discoveries of the future? That’s the question Chancellor Rachel Reeves had to try to answer with this week’s Spending Review. She allocated more than 22 billion pounds a year by 2029/30 for research and development which was described as a boost for science. Robin Bisson, UK News Editor for news website Research Professional News, and Dr Alicia Greated, Executive Director at the charity Campaign for Science and Engineering in the UK, explain where the money will go.As the UN’s Ocean Conference continues in Nice, France, we get the latest developments from Science and Climate Correspondent Esme Stallard, before diving into a kelp forest in our own UK waters with reporter Graihagh Jackson.

Can science save our oceans?

Can science save our oceans?

More than 2,000 marine scientists have come together at the One Ocean Science Congress in Nice, France. It is a gathering that will bring marine experts from all over the world together to share the latest discoveries about the health of our seas and oceans. It is an issue at the centre of the world’s attention, because from 9th June, leaders and negotiators from 200 countries will arrive in Nice for the crucial United Nations Conference on the Oceans (UNOC3). Presenter Victoria Gill is joined by Murray Roberts, Professor of Marine Biology at the University of Edinburgh to find out what is at stake when leaders come together to work out a global plan to save our oceans from multiple threats, including climate change, pollution and overfishing. Professor Amanda Vincent from the University of British Columbia in Canada joins the Inside Science team to reveal her insights into the destruction caused by the controversial fishing practice of bottom trawling, which she explains is devastating marine life. Victoria also joins a team of acoustic marine scientists on their research boat the “We Explore” off the coast of Nice to listen for whales and dolphins under the surface. Their sound recordings reveal how animals of different species eavesdrop on each other and how to stop boat noise from drowning out whale communication. We also meet a team from a charity in Plymouth that is helping people who are living with poor mental health by prescribing ocean-based activities. Freyja Thomson-Alberts from the organisation the Ocean Conservation Trust explains why the ocean is central to our physical and mental wellbeing.Presenter: Victoria Gill Producers: Dan Welsh, Clare Salisbury, Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth
