A new Covid vaccine – which targets both the original virus and one of the latest Omicron variants – has been approved for use in the UK. About half of the 26 million older and vulnerable adults in the UK who are due a booster this autumn should get the new vaccine.

There’s news of British scientists changing the blood group of donated kidneys – which could boost the supply of organs for transplant. Professor Magdi Yaqoob says switching to blood type O means the organs can be transplanted into any patient. We hear from Ravi Singh whose life was transformed last month when he got a new kidney from a live donor. He wants everyone to discuss donating with their family and to carry a donor card.

The pandemic delayed hospital treatment for many – so to help deal with waiting lists some hospitals are trying out 'overlapping' surgery – with one senior surgeon supervising two operating theatres, and more junior surgeons carrying out the more straightforward parts. When it was tried in the US there were concerns around consent and safety but we hear how only doing 30 minute procedures means that a month’s worth of operations can be done in a day.

In the pandemic when intensive care units were full and visitors were not allowed some families kept in touch using phones and tablets. A new study in the UK shows that this “virtual” visiting did help to reduce the distress felt by relatives – and the practice still continues to keep families in touch when they live far apart.

Training relatives to give medicines at home to ease their loved ones’ symptoms at the end of life was pioneered in Australia. This week a specially-adapted version of the caring@home programme is being launched to support Aboriginal and Torres Strait Island families. The practice is catching on in the UK - we hear from Mark who helped ease his mother’s pain and nausea at the end of her life.

Dr Graham Easton from Barts and the London has news of a study from India showing how small differences in the beating heart could help to predict the risk of diabetes developing. He also warns that doctors need to stop fat shaming people to help them lose weight – and how blood pressure should be taken in both arms.

In the cut throat world of work, can bosses be kind? Claudia Hammond unpicks the psychological evidence from around the world to find out if it’s possible for managers to be both kind all the time and successful.

The quest starts with Thom Elliot Co-founder of Pizza Pilgrims in the UK, who deliberately set out to foster a kind culture in a sector not exactly known for its benevolence. They're joined for pizza by Prof Robin Banerjee, architect of the Kindness Test to discuss the findings and examine whether kindness in business really does result in success. Joe Folkman is the perfect person to ask. He runs an evidence based leadership development firm in the US. It turns out there's a strong correlation between being likeable and effectiveness. Such concepts are backed up by a relatively new field of research called 'ethical leadership' pioneered by Professor Mike Brown.

Claudia meets former head teacher Ros McMullen who tells some home truths about leadership in a culture of relentless pressure and accountability.

Plus Lisa Smosarski, editor in Chief of Stylist magazine shares shocking office stories of the 'Devil Wears Prada' era and discusses wider societal shifts that may be contributing to a kinder culture in her industry.

What can the latest research tell us about whether there is any such thing as pure kindness? Claudia Hammond meets a man who has done an exceptionally altruistic act for someone who was seriously ill. What prompts acts of kindness like this? Specialists from the fields of psychology and neuroscience unpick the evidence.

As Covid cases rise new recommendations from European health agencies back over 60s to get boosted. Professor Monica Lakhanpaul from University College London explains that this is before the rollout of updated vaccines to target specific variants. Monica also discusses her own research with village communities in India working to benefit infant nutrition.

Also, with the numbers of teenagers experiencing mental health difficulties rising in many parts of the world some schools have turned to mindfulness classes. But how effective are they? Co-author professor Willem Kuyken discusses the results of the long awaited eight year study. Plus is there such a thing as too much confidence?

Claudia Hammond is at the Royal Society Summer Science Exhibition in London looking at the latest medical research. Claudia speaks to Professor Tamar Makin and designer Dani Clode to find out whether a third thumb might be handy. Dr Simon Gubbins explains how to use genetic technology to head off the world’s next pandemic before it happens. And Claudia hears from Dr Georgina Girt why llamas are special. They’re certainly cute with their pointy ears and their long eyelashes, but they can also develop tiny antibodies that could protect humans against numerous different diseases. Plus senior lecturer, Chloe James on the super powers of bacteriophages and how they work as puppet masters.

Online misinformation about polio has gone global after the detection of so called vaccine-derived poliovirus in London sewage. BBC health and science correspondent James Gallagher explains what’s really happening. And Claudia Hammond talks to Professor Beate Kampmann from the London School of Hygiene and Tropical Medicine who explains that while vaccine-derived polio virus has been reported in 24 countries since 2021 the vaccination programme has protected millions of people.
