Many of us can empathise with that feeling of keeping stuff for years and years. We might keep treasured objects with real sentimental value, or we might have items for a long time - and yet we can't really explain why. For those of us who don’t like getting rid of our belongings, life can feel very full of stuff. But when does a tendency to hold on to things become more worrying? It can be difficult to put a figure on just how many people have what's known as hoarding disorder. So what causes this complex and little discussed issue – and is it more than just a problem of too much stuff? Claudia visits a woman who describes how hoarding has taken over her life to the extent that she doesn’t let anyone into her home. We also meet her psychologist to understand what underpins hoarding disorder and how it’s treated.

In the past decade there has been little progress in lowering malaria cases, with over half a million people still dying from the mosquito-borne disease every year. We look at the big ideas and innovations of the future that could help us eliminate malaria once and for all. What would happen if we got rid of the insect responsible for spreading the malaria parasite? Claudia heads to Imperial College London where she is joined by Dr Federica Bernardini and their 120 colonies of mosquitos to find out how revolutionary genetic technologies are aiming to do just that.Picking up on Imperial’s work in the field is Principal Investigator at Target Malaria in Uganda, Dr Jonathan Kayondo.

But that investment is starting to pay off - 2025 has been a big year for new ways of tackling the disease.This week we’re reflecting on the progress made in 2025 – but also asking what impact unprecedented cuts to global health funding might have on whether children living in hot and humid regions of the world contract malaria.
