Halfway to net zero; hydrogen as a fuel; Fagradalsfjall, Iceland’s active volcano

The UK is reportedly halfway towards meeting its 2050 target of "net zero" carbon emissions. How did we get there and how will we achieve the next stage?

‘UK greenhouse gas emissions in 2020 were 51% below 1990 levels, according to a new Carbon Brief analysis. This means the UK is now halfway to meeting its target of “net-zero” emissions by 2050.’ Simon Evans explains his predictions from the report, outlines how we define net zero and what is required from the next few decades to ensure that the UK meets its 2050 goal.

Much of Europe is attempting to replace fossil fuels, transforming transport and domestic heating to run on electrical alternatives, such as batteries and heat pumps. But where electrification isn’t possible or cost effective, such as in many homes, an alternative is still needed. Natural gas is responsible for over 30% of the UK’s total carbon emissions. Hydrogen would, theoretically, appear to be the perfect alternative, as combustion only produces water as a by product. Gaia discusses the options with hydrogen strategist, Dr Jenifer Baxter, and Dr Angela Needle of Cadent explains the pilot projects the company is carrying out to introduce 20% hydrogen into gas going into our homes.

Last Friday, Fragradalsfjall began erupting for the first time in 800 years. The volcanic system is located in the West of Iceland close to the capital city of Reyjkavik. Dr Evgenia Ilynskaya of Leeds University has been out measuring the gases emitted by the eruption and she describes the experience of working on an active volcanic system.

Wild Britain

Wild Britain

In 2020, the UK government committed to protecting at least 30% of land and sea for nature by 2030. Step seven years into the future with Gaia. The UK has achieved its biodiversity goal, but what does wild Britain look like? Richard Benwell, CEO of wildlife and Countryside Link, Meredith Whitten, a researcher and urban environment planner at LSE, Hugo Tagholm, CEO of Oceana and George Monbiot, an environmental writer whose book Regenesis explores sustainable agriculture, describe this radical new world.

70th anniversary of the discovery of DNA’s structure

70th anniversary of the discovery of DNA’s structure

James Watson and Francis Crick, who detailed the double-helix structure of DNA in 1953, are perhaps two of the most iconic scientists of the 20th Century. Yet the story of how they made their incredible discovery is perhaps equally famous, with a notorious narrative suggesting that they only identified the structure after taking the work of Rosalind Franklin and using it without her permission. Now, 70 years after the discovery of DNA’s structure, it is perhaps time to rewrite the tale. New evidence has now been unearthed, in the form of an overlooked news article and an unpublished letter, that shows that Franklin was truly an equal contributor to the discovery, and Watson and Crick were not as malicious as previously assumed. Together with Matthew Cobb of the University of Manchester, Nathaniel Comfort from Johns Hopkins University, and Angela Creager of Princeton University, Gaia Vince discusses this tantalising tale and finds out more about how this discovery could bring a whole new twist to the story of DNA.

Rocket Launch Pollution

Rocket Launch Pollution

Whilst the globe struggles to shift to green sustainable energy sources, one industry has its sights set solely on the stars. Space X just launched the biggest rocket the world’s ever seen, and it won’t be their last even if it did end its test flight with a bang. As we enter a new golden age of space travel, Vic asks Associate Professor in Physical Geography Dr Eloise Marais if we are paying enough attention to the environmental impacts posed by a rapidly growing space industry. Have viruses, bacteria, and microorganisms influenced humanity more than we know? Author of new book, Pathogenesis: How Germs Made History, Dr Jonathan Kennedy discusses how germs and disease have shaped human evolution, history and culture and what we can learn from the COVID pandemic. And from unconventional life in space to psychoactive spinning apes, Vic and BBC Climate Reporter Georgina Rannard bring you the best scientific stories from the past couple of weeks.

Negotiation

Negotiation

When was the last time you had to use your negotiating skills? Did you walk away satisfied? This week junior doctors are half way through their 4 day walkout, with senior NHS figures suggesting the cancellation of between 250,000 and 350,000 appointments/operations. Victoria Gill is preparing to debate her way through the science of disagreement and identify what qualities make for the perfect negotiator. Associate Professor Sunny Lee, Deputy Director of Equality, Diversity, and Inclusion at University College London helps guide Victoria through the basic building blocks that help resolve conflict, with expert commentary from Camilla Born peeking behind the curtain of COP26, and finally negotiating with elephants? Dr Josh Plotnik at City University of New York suggests that some animals may be actively seeking out conflict with humans.Presenter: Victoria Gill Producer: Harrison Lewis

Net Zero

Net Zero

Far away and not enough, those are criticisms of the government’s latest net zero initiative – a plan to reduce emissions . We ask Jim Watson Professor of Energy Policy and Director of the UCL Institute for Sustainable Resources for his assessment.And there’s money to be made from private health testing, the growth of Covid testing has been followed by an upsurge in private screening for cancer in particular, but how useful is it really? BBC Health correspondent Matthew Hill takes a look.Every cell in out body carries an electrical charge. In her new book, We Are Electric: The New Science of Our Body’s Electrome, Sally Adee discusses how this facet might be harnessed for the detection of illnesses, medical treatments and whether it will allow us to develop hidden powers.The World Wood Web is a concept showing how trees communicate with each other through an underground fungal network. The idea was first proposed by Suzanne Simard, Now professor of Forest Ecology at the University of British Columbia, who tells us how she came up with the concept and about her work on the hidden relationships of trees.

Covid – missing link found?

Covid – missing link found?

Data collated from swab samples taken in Wuhan’s market in the early days of the Covid pandemic suggest animals sold in the market were carrying the virus at the time. It’s the strongest evidence yet for an intermediate species – one which passed the virus on to humans after becoming infected by bats carrying the virus. Dr Florence Debarre from the Institute of ecology and environmental sciences, in Paris and Professor Eddie Holmes from Sydney University discuss the findings. Beethoven’s genome has been reconstructed from samples of his hair. It reveals some of his medical history, but also unexpected findings on his paternity. We discuss the ethics of such genetic analysis with Tom Booth who studies ancient DNA at the Francis Crick institute. And microbes may help us survive and thrive in space according to Astrobiologist Rosa Santomartino, not only that but their recycling capabilities could also help us on earth

Sweet Science

Sweet Science

Researchers from London’s Francis Crick Institute have found a type of artificial sweetener is able to dampen down immune system responses - at least in mice. Karen Vousden and Fabio Zani tell us about the implications. And Ronan McCarthy from Brunel University has found a range of different artificial sweeteners have antibacterial properties. We discuss the connections between these two areas of research and the prospect of developing drug treatments from artificial sweeteners. Penny Johnes from Bristol University discusses the use of phosphorus in agriculture, it’s a key component of fertilisers, but global supplies may run out in a few years, despite this overuse of phosphorus in agriculture is also creating problems. And Chat GPT has had a makeover, a new version of the chatbot was rolled out this week. Chatbots seem to be getting a lot of press at the moment, but are they really something we will all be using in the future? Technologist and composer LJ Rich who works with the UN on artificial intelligence gives us her analysis.BBC Inside Science is produced in collaboration with the Open University.
