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.

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.

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.

Former Energy Minister Chris Skidmore’s report into Net Zero calls for ambitious policies to drive energy transition, framing it as a huge economic opportunity to drive national growth.

Using and conserving energy in the home is one theme the report tackles.

We discuss home insulation with Colm Britchfield , policy advisor at E3G. His recent report found those in some of the worst housing , in the private rented sector could save hundreds of pounds a year if their homes were properly insulated. But what is the incentive for landlords to pay for insulation?

Electric heat pumps have been heralded as an alternative to gas boilers, but they are currently more expensive and finding an installer is not easy.

And what is the role of local authorities in the strive for net zero? We hear from Polly Billington, chief executive of UK 100 – a network of local government leaders committed to sustainability policies.

How do you catch a poacher? One way might be through their own mobile phone. Another is using a camera trap which sends a signal to game wardens. These are technologies developed by Tim Van Deursen and Thijs Suijten from Hack the Poacher.

And we look at new findings on one of Australia’s Iconic species – Echidnas.

ChatGPT (Generative Pre-trained Transformer) is an online conversational chatbot, launched by OpenAI in November 2022. To date it remains an online sensation, allowing users to generate poems, essays, code and images in seconds. But fear bubbles in academic circles that artificial intelligence could promote plagiarism in secondary and tertiary education. Technology writer and broadcaster Bill Thompson, and teacher of 20 years digital philosopher Rebecca Mace from University of West London suggest the news headlines may be sensationalising the impact this chatbot will have on student learning.

The 1922 backbench committee on business, energy and industrial strategy is recommending free electricity for locals residing within 1 mile of onshore wind farms. Richard Black, senior associate at Energy and Climate Intelligence Unit, joins Marnie to discuss whether or not there is evidence of residents requiring incentives to accept renewable developments whilst governments strive to increase the implementation of green technologies.

Do you tap your toes to Paul Simon or rock out to Led Zeppelin? Even if you have two left feet, your ability to recognise rhythm is unique in the animal kingdom. To help determine the human origins of musical appreciation, Teresa Raimondi and her team at Turin University, have been researching primates. Their singing lar gibbon, appears to share similar traits to us that might shed light on where our ability to keep the beat evolved from.

And finally, figures from the water regulator suggest that in England and Wales 1 trillion litres of water was lost last year to leaks. BBC Inside Science presenter, Vic Gill, goes in search of what might be a robotic solution.

This programme was made in partnership with the Open University.

The UK's first satellite launch faced several delays in 2022, but Virgin Orbit's Cosmic Girl is prepped for imminent take off. BBC science correspondent Jonathan Amos has been following the activity in Newquay and, alongside Melissa Thorpe head of Spaceport Cornwall, describes the potential this launch has to promote and bolster the UK's space industry.

Is laziness a particularly human trait? Apparently not according to Dr Daniella Rabaiotti from the Zoological Society of London. Her research shows many animals engage in behaviour akin to laziness even within groups where others might be very active. There’s evidence for this from animals as diverse as wolves, frogs and pheasants. Dani says it’s a factor worth considering in animal behaviour studies, simply are we biased towards the more active and outgoing animals as they are the ones we tend to see?

Victoria Gill speaks to the founder and CEO of Nature Metrics Dr Cat Bruce and Katie Critchlow about the tools they use to help companies measure biodiversity at their worksites. From taking water or soil samples it’s possible to detect the DNA of a multitude of organisms from large animals down to microbes. The technique should help map the biodiversity of a given area and inform decisions on development and conservation.

Nations are racing to protect 30% of the planet by 2030 in an attempt to halt biodiversity loss, but one novel approach may be able to safeguard species under threat of imminent extinction. Vic visited Nature’s Safe in May, a cryogenic biobank, storing the genetic information of at risk species in futuristic biological freezers. But will it serve as a viable tool to bring wildlife back from the brink if the ecosystems in which these animals reside are degraded beyond repair?

The Greenland ice sheet is melting, raising global sea level at an alarming rate. Marnie took to the ice with researcher Jason Box in September, and questions how current carbon emissions will influence melting in the future.

Gaia revisits UN talks from March that attempted to put in place regulations capable of protecting the marine biodiversity of the high seas. Negotiations were unsuccessful at the time, but further talks have been held since. How much progress has been made?

How many Scientists does it take to cook Christmas dinner? Marnie seeks help from a food scientist, a geneticist, a doctor and a botanist to create the perfect festive feast.

Base editing is a technique for substituting the building blocks of DNA. It has only been around for a few years, so its use to apparently cure cancer was all the more remarkable, as BBC Health Correspondent James Gallagher tells us.

We take a trip down the river Wye with ecologist Steve Ormerod who tells us why the river is a microcosm for some of the global issues being discussed at the UN Biodiversity summit in Montreal. BBC Environment Correspondent Victoria Gill gives us the latest on the state of negotiations there.

And the current surge in infections associated with the streptococcus bacteria has led to deaths in a few cases. It is usually a seasonal infection, worse in the spring. We ask microbiologist Dr Claire Turner from Sheffield University why we seem to be seeing a surge of infections now and her research on strep vaccine targets.
