Researchers have discovered a species of bacteria which dwarfs all others by thousands of times. Normally you need a microscope to see single-celled bacteria, but Thiomargarita magnifica is the length and width of an eyelash. It's been found growing in mangrove swamps in the Caribbean. Roland Pease talks to Jean Marie Volland about what makes this Godzilla of the microbial world extra-special. Also in the programme, a new study published in the journal Nature has discovered that women scientists are less likely than their male peers to be credited for their contributions to research projects. Roland discusses the findings with the study leader Julia Lane of New York University and nanoscientist Shobhana Narasimhan in Bangalore. We also find out about the oldest evidence for wildfires on the planet which raged across the land 430 million years ago, with palaeobotanist Ian Glasspool. And Edinburgh University vertebrate palaeontologist Steve Brusatte talks about some of the evolutionary wonders in his new book The Rise and Reign of the Mammals. Death is inevitable, though many of us would rather not dwell on it. For those with a terminal illness, however, the end of life is clearly a more pressing reality. CrowdScience listener Sam has known for a while that her illness is terminal, and by now she’s got used to the idea. But she finds many friends and family would rather avoid the subject at all costs; they don’t want to acknowledge what’s happening until it’s all over. She’s wondering if there’s a way to lighten up the topic of her approaching death, and create the openness she craves. If we could learn to be more accepting of illness and dying, the end of life could be a more positive experience for all involved. So how can we face up to the impending death of a loved one, and best support that person in the process? In search of answers, we talk a clinical psychologist about death anxiety, visit a death café, and learn about a scheme in India where whole communities are trained in caring for people at the end of life.
