Three people have died after an outbreak of hantavirus onboard a cruise ship travelling from Argentina to Cape Verde. The World Health Organization says a total of seven cases – two confirmed by laboratory testing and five suspected – have been identified on the cruise ship so far. It is also investigating whether rare human-to-human transmission of the virus could be behind the cases. Madeleine Finlay talks to Prof Jonathan Ball from Liverpool School of Tropical Medicine to find out where the virus comes from, how it is transmitted to humans, and what health agencies will be doing to try to contain it.

The transition towards renewable energy received a boost last week when representatives from 57 countries met in Santa Marta, Colombia, for a world-first climate meeting aimed at bringing the fossil fuels era to an end. Madeleine Finlay hears from the Guardian’s global environment editor, Jon Watts, about how the landmark conference came about, who was missing, and whether the optimism can translate into real world action.

Madeleine Finlay sits down with co-host and Guardian science editor Ian Sample to talk through three eye-catching stories from the week, including the news that the number of years people in the UK are spending in good health has declined compared with a decade ago. Also on the agenda is the science, tech and nutrition behind two runners at this weekend’s London marathon breaking the two-hour threshold, and an answer to why some old houses feel particularly spooky.

Social media is awash with content about food intolerances and the symptoms to look out for. But figuring out whether you actually have one, and what’s triggering it, is surprisingly difficult. One avenue people are gravitating towards is at-home testing. Madeleine Finlay sits down with health and lifestyle journalist Rebecca Seal to unpick the science behind these tests. Rebecca explains how they purport to work, how accurate they actually are, and how we can all investigate what we might be intolerant to, without breaking the bank. Rebecca’s book Irritated: The Allergy Epidemic and What We Can Do About It, is out now.. Help support our independent journalism at theguardian.com/sciencepod

Madeleine Finlay sits down with science editor Ian Sample to hear about some of the winners of the Breakthrough Prize, which held its ceremony in LA last weekend. Each prize is worth $3m and they’re awarded in physics, maths and life sciences. Madeleine and Ian hear from molecular biologist Jean Bennett, who shared a life sciences prize for her work developing the world’s first FDA-approved gene augmented therapy for sight loss. She explains how a chance encounter while dissecting a brain in medical school led her on a 25-year journey to develop the treatment..
