Roland Pease reports from the American Association for the Advancement of Science’s annual meeting in Seattle. At the UK Research and Innovation’s stand in the exhibition hall, he’s joined by three scientists to discuss monitoring the Coronavirus outbreak, the locusts devastating crops in East Africa and the ever increasing amount of space junk orbiting the Earth.
Professor Jeffrey Shaman of the Mailman School of Public Health at Columbia University talks about how he is modelling the movement of Covid-19 around China and beyond.
Dr Catherine Nakalembe, of the University of Maryland and East Africa Lead for NASA Harvest explains how she uses data collected by satellites to find out where crops are thriving and where they are not. She also talks about how this technology can alert countries to approaching locust swarms.
And Professor Moriba Jah of University of Texas at Austin, tells Roland why he’s concerned about the amount of space junk that’s orbiting the earth and why so little is being done about controlling satellite launch and disposal.

With the announcement in the UK of investment in rapid testing for people who may not have Covid -19 we ask why is this only happening now? For months on this programme we’ve featured scientific research suggesting such a strategy would be the quickest way to end the pandemic.
We speak with Connie Cepko and Brian Rabe who have developed a rapid test and Manu Prakash who is currently rolling it out to countries in the global south.
Could a huge motorcycle rally really have been the source of over a quarter of a million Covid -19 infections? That’s the finding of a study by economist Andrew Friedson he tells us how mobile phone data helped to determine that figure.
And the politics of vaccines, Many health officials in the US have spoken out against president Trumps claim that a vaccine may be ready before the November presidential election. Helen Branswell from Stat news tells us why there is so much concern over political attempts to manipulate science.
And Many of us enjoy cooking – but when did we switch from eating our food raw, to heating it? Listener Logan enjoys his beef burgers rare, but wants to know why he still feels compelled to grill them? Presenter Anand Jagatia travels to a remote South African cave where our ancestors first used fire at least a million years ago, which one man says could help prove when our species started cooking.
And he talks to a scientist who shows how the composition of food changes when it’s cooked, to allow us more access to give us more access to calories - and hears how a completely raw food diet could have disastrous consequences for health.

This month’s World Book Club is the ninth in our series celebrating the greatest women writers at work across the globe. Harriett Gilbert and listeners from around the world talk to the world-renowned American author Elizabeth Strout at her home in New Brunswick, Maine, in the USA.
The novel under discussion is her internationally-garlanded Olive Kitteridge: a novel made up of 13 luminous short stories set in small-town Maine and bound together by one larger-than-life character, the flawed and fascinating Olive Kitteridge.
Retired school teacher and long-time wife of the long-suffering Henry, Olive struggles to make sense of the changes in her life and the lives of those around her. Her travails, at once parochial but also universal, make readers laugh, nod in recognition, as well as wince in pain.

A new survey of the volcano's activity suggests there may be an eruption in the next 4 to 7 years. It's a particular concern for the populations of Goma and Gisenyi, two cites between the volcano and lake Kivu. As we hear from the director of the Goma Volcano Observatory Katcho Karume, the city of Goma in particular has expanded so much that many people now live right next to fissures in the flank of the volcano through which any eruption would likely occur.
Hurricane Laura made landfall in Louisiana's main area of swamp land, missing big urban areas to either side. It was a lucky escape for many, but as hurricane historian Jill Trepanier tells us such extreme weather events do seem to be more frequent and potentially more destructive.
And wildfires ravaging California and other Western US states may have been intensified by changes to global weather systems . Climate scientist Bill Lau says those weather systems in turn have been modified by man-made climate change.
In November 2018 a Chinese scientist announced he had edited the genes of twin girls. The announcement was greeted with horror by many researchers in the field. Now a way to regulate gene editing internationally has been proposed by some of the world's leading scientific institutions. Kay Davies co-author of their report explains the plan.
What does science say about controlling urination, and other bodily functions? We tackle three queries about peeing triggers, pooing positions and missing sweat. This episode CrowdScience presenter Marnie Chesterton poses some of the best listener follow-up questions that have landed in our inbox to a panel of experts.
Listener Samuel in Ghana is wondering why watery sounds seem to induce urination. Producer Melanie Brown heads out to survey whether this is the case for individuals in an actual crowd at a public fountain in London. And urologist and trustee of the International Continence Society Marcus Drake talks Marnie through how he uses the sound of running water during his work as a hospital doctor helping patients with common but distressing peeing issues, and the limitations of research into this question.
And he's not the only listener who wants us to dig deeper into topics we've explored on the show before. Anna in Tokyo also got in touch after hearing our show about toilets, to ask if there is a toilet design that is most 'natural' for our health. Gastroenterologist Anton Emmanuel explains why small changes in people's posture whilst pooing can have a significant impact on their quality of life.
Finally, listeners Stelle, James and Joel emailed crowdscience@bbc.co.uk after hearing Marnie investigate hyperhidrosis: Sweating too much. They and their relatives experience the opposite.

This week Science in Action examines the evidence around the Trump Administration’s emergency use authorisation of convalescent plasma therapy for the treatment of Covid-19. Donald Trump described its US-wide roll-out as ‘historic’ but the majority of scientists and doctors disagree, questioning the scientific basis for the government’s decision. Roland Pease talks to Mayo Clinic’s Michael Joyner, the leader of the convalescent plasma therapy study on which the action was based. The Mayo Clinic trial involved a large number of patients but none of them were compared to Covid-19 patients who were not treated with convalescent plasma. Trials that incorporate that comparison are the only way to properly assess the therapy’s effectiveness. Roland talks to Martin Landray of the University of Oxford who is testing convalescent plasma therapy in the UK’s Recovery randomised control trial, and to medical ethicist Alison Bateman-House of the New York University Grossman School of Medicine.
We also talk to nanotechnologist Marc Miskin about the million-strong army of microscopic robots he’s creating in his lab at the University of Pennsylvania.
The idea of creating underwater habitats has captured the imagination of writers, thinkers and scientists for decades. However, despite numerous grand visions, these dreams of aquatic metropolises have not yet come to fruition. Crowdscience listener and scuba enthusiast Jack wonders whether - given improved technology and the growing environmental pressures facing humans on land - it is time to reconsider the ocean as an alternative permanent living space for humans. Marnie Chesterton dons her flippers for Crowdscience in search of the oceanographers and architects who have dedicated their lives to designing vessels, labs and underwater habitats. She explores whether oceanic cities remain a sci-fi dream or a realistic solution to some of our modern challenges. Can the oceans’ largely unexplored resources be harnessed to support living underwater?
