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.

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

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.

The government has launched a new 10-point plan designed, it said to “cement the UK’s place as a global science and technology superpower”. We speak with Sir Paul Nurse, director of the Francis Crick Institute, for his take on the government's plan and the findings of his own review of the UK’s research landscape. In 1963, in a now famous speech at the Labour Party conference in Scarborough, Labour leader and soon to be Prime Minister Harold Wilson promised a new Britain would be forged in the “white heat" of a "scientific revolution". Nick Thomas Symonds, Labour MP and political biographer, discusses how that idea was put into action. Scientists in Bristol have published a detailed "future flood map" of Britain - simulating the impacts of flooding as climate change takes its toll. Paul Bates from Bristol University explains how the new flood risk maps give a level of detail that could help people to plan and adapt. Vic Gill visits the Calder Valley in West Yorkshire, a place that’s suffered repeated flooding in recent years, where the community is taking matters into its own hands. New fossil findings from China have led scientists to re-evaluate their classification of tiny tentacled sea creatures from half a billion years ago and declare that they are in fact seaweeds says Martin Smith, a paleobiologist from The University of Durham. And this re-classification isn't unusual, fossils are constantly re-examined in light of new evidence and insights. Susie Maidment a paleobiologist at the Natural History Museum takes us through some of her favourite contentious fossils.

Science writer Philip Ball has followed the relationship between government and its scientific advisors throughout the pandemic. He discusses the role of scientific advisors in the light of conflicting information following the leak of a number of former Health Minister Matt Hancock’s WhatsApp messages. Phil tells us why he believes greater transpearency is needed around the advice offered to government. The head of the US FBI has suggested the Covid 19 pandemic may have been started through a leak from a laboratory. No evidence has been offered. The ‘lab leak ‘ theory is the counter idea to Covid having a natural origin. We hear from three scientists who have been to China to investigate different aspects of the virus origins story.Journalist and microbiologist Jane Qui visited the Wuhan Institute of Virology – the lab at the centre of the lab leak theory.Marion Koopmans from Erasmus University in Rotterdam was a member of the WHO mission to China to investigate the origins of Covid 19.And Eddie Holmes from the University of Sydney visited the market in Wuhan, the epicentre of the outbreak.Besides inflating party balloons helium gas has a vast range of industrial uses, particularly as a coolant. There’s a world shortage, and helium is only extracted with fossil fuels such as coal and methane gas. Earth scientist Anran Cheng at the University of Oxford has developed a method to look for helium deposits without the fossil fuel connection.And ever wondered how heavy all the animals in the world might be ? We have the answer thanks to Ron Milo and Lior Greenspoon from the Weizmann Institute of Science in Israel.BBC Inside Science is produced in partnership with the Open University.

Sea ice coverage hit a recording-breaking low in the Antarctic this week, but what does this mean for the rest of the world? Why is the region so difficult to predict? And what could further changes in climate mean for the South Pole? Often the Arctic dominates conversations around polar warming but this week, with the help of climate modelling expert Tamsin Edwards, Kings College London, we’ll be tackling these questions and more. We’ll hear from British Antarctic Survey researcher Nadia Frontier, a marine biologist spending the summer at Rothera research base in the Antarctic. We join her as she traverses snow and ice to study the inhabitants of Adelaide island and the surrounding waters. Rachel Tilling from the Cryospheric Sciences Lab at NASA’s Goddard Space Flight Center helps us explore the continent from a different vantage point, explaining her work using satellite data to understand sea ice thickness. And climate reporter Georgina Rannard takes us through an artistic interpretation of polar sounds, Dr Geraint Rhys Whittaker uses underwater microphones to capture the impact of human activity on polar wildlife.

Chinese biophysicist He Jiankui caused international outrage when in 2018 when he used the gene-editing tool known as CRISPR Cas-9 to edit the genomes of two human embryos. That experiment, described by the Chinese Academy of Science and Technology described as ‘abominable’, resulted in the birth of twin girls. The experiment also landed Dr He in prison for three years. Now, out of prison and working for a company in Beijing that proclaims to offer “affordable gene therapy” – He Jiankui has been speaking in public. At an open bioethics event at the University of Kent last weekend, organisers invited the scientist to present his research and to face questions about his past experiments and his future plans. We spoke to event organiser Dr Joy Zhang about the reaction to event and to Professor Robin Lovell-Badge at the Crick Institute about the implications of CRISPR-CAS9 technology. A Hippo butchery site reveals that distant human ancestors have been using stone tools far longer than researchers previously thought. This archaeological site in Kenya revealed that ancient hominins Paranthropus have probably been using stone tools to prepare food and weapons since 2.9 million years ago. Professor Tom Plummer at Queens College, City University of New York take us through the discovery and what it reveals about hominin evolution. A study released this week reveals just how much of a burden sons are on killer whale mothers. Michael Wiess, research director at the centre for whale research, fills us in on their findings which are a product of nearly 40 years studying the southern resident Orca population. This long-term Whale census project began in the 70s, championed by researcher Ken Balcomb, who was passionate about understanding and protecting killer whales and who sadly passed away late last year. We hear from Ken and his team out on the water studying the southern residents, more of which can be found in BBC Radio 4 documentary The Whale Menopause.

This week’s programme is a thought experiment: What would the world be like if energy became superabundant and very cheap?Energy is vital for every aspect of our society, and the energy cost of extraction, processing, manufacture and transport is priced into every product we buy. Today’s energy crisis is having a huge impact, from affecting diplomatic relations between nations to the availability of food. How can our energy systems evolve and what could cheap abundant energy mean for us, our relationship to the natural world, and each other?We discuss these issues and more with;Rachel Kyte CMG, Dean of The Fletcher School at Tufts University, who has previously worked for the UN on sustainability issues.Jim Watson, Professor of Energy Policy at UCL. He’s advised government on the low carbon energy transition.And Dr Hannah Richie, Head of Research at Our World in Data, based at Oxford University, who looks at food, agriculture and energy in relation to global development trends.

Defra, the department for Environment, food and Rural affairs, released its latest Environmental Improvement plan this week. Many environmental groups have criticised the plan for having vague commitments, and landowners are asking where the money is going to come from if say farmers are going to move land out of production and into conservation. For a view away from these vested interests we’ve turned to the Office of Environmental protection – the body set up after Britain left the EU to scrutinise government environmental policy. Chief Executive Dame Glenys Stacey, and Chief Insights Officer, Professor Robbie McDonald. Last week the UK passed an emergency exemption allowing sugar beet farmers to use a controversial neonicotinoid pesticide called Thiamethoxam. This is the third year in a row that the exemption has been in place and the decision came just days after the EU banned such exemptions across Europe. A discussion in parliament yesterday saw MPs criticise the move due to the impacts of neonicotinoids on already crashing Bees populations. We spoke to Dr Richard Gill at Imperial College London about exactly how these insecticides impact bees. There are volcanic islands dotted across the globe but exactly what caused their formation and how might they change in the future? Professor Ana Ferreira at University College London is a seismologist leading an ambitious study to measure deep vibrations and disturbances around volcanic islands in the Atlantic Ocean. She told us about the challenges of recording from the ocean floor and the other unexpected disturbances they detected. As humans our eyes are one of our most valuable and expressive social tools. The whites of our eyes or sclera enable us to follow each others gaze and look our for minute changes in mood, a feature that until recently was thought to be unique to humans setting us apart from animals in our ability to communicate. But Anthropologist Aaron Sandel at The University of Texas in Austin has noticed that white sclera is in fact present in one of our closest relatives; the chimpanzee.Presenter: Gaia Vince Producers: Julian Siddle and Emily Bird Inside Science is produced in Collaboration with the Open University

What if all schools offered only plant-based options for 3 out of 5 lunches a week? Would that be enough to trigger a broader societal shift to eating less meat, and allow us to meet our sustainability commitments?We’re not talking about making school dinners entirely vegetarian — just 3 lunches a week.We discuss the benefits and practicalities of such a shift with :Tim Lenton, Professor of Climate change at the University of Exeter.Economist Marco Springmann Senior Researcher, Oxford Martin Programme on the Future of Food, University of Oxford.Nutritionist Collete Fox from Proveg international an organisation working directly with schools in the UK to encourage the provision of healthier school meals. And Henry Dimbleby founder of the Leon fast food chain is now an advisor to government, responsible for drawing up national rules on school dinners.We also visit Barrowford primary in Lancashire, which has successfully rolled out more vegetarian school dinners.BBC Inside Science is produced is partnership with the Open University.
