With many of Australia's hillsides stripped bare by fire, scientists are rushing to predict where mudslides could be triggered by rainfall. NPR science reporter Rebecca Hersher and photographer Meredith Rizzo traveled to Australia to learn how they're doing it. More of their reporting (with photos) is here.

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.

A lovely day out in the countryside can be blighted when swarms of midges or mosquitos invite themselves to the party. A CrowdScience listener in New Zealand has noticed that, when sand-flies come a-biting, she and her daughter are targeted, while her husband and other daughter escape unharmed. She wants to know why some, but not all of her family become bait for insect bites. CrowdScience delves into a world of smells, called semiochemistry, which explores the aromas one animal uses to attract or repel another. Does our attractiveness as a blood meal to insects come down to what we wear, what we’ve eaten or is it all in our genes? Host Marnie Chesterton discards the DEET and bravely offers herself up as a meal for mozzies, in a quest for answers.

Wingspan is a board game that brings the world of ornithology into the living room. The game comes with 170 illustrated birds cards, each equipped with a power that reflects that bird's behavior in nature. Wingspan game designer Elizabeth Hargrave speaks with Short Wave's Emily Kwong about her quest to blend scientific accuracy with modern board game design.

Harvard chemist Charles Lieber was arrested in January on charges he lied about funding he received from China. Some say the case points to larger issues around scientific collaboration in an era of geopolitical rivalry, as well as the racial profiling of scientists.

It's possible — but it depends on a few key factors. NPR health correspondent Allison Aubrey explains, and tells the story of the scientist who uncovered the importance of zinc for human health in the first place.

Researchers at the London School of Hygiene and Tropical medicine have developed an online map which presents the latest information on the spread of CoVid-19 and allows anyone to follow the outbreak and compare this data with the spread of Ebola and SARS. See the weblink from this page to try it for yourself.

And the coming together of microbiology and big data science has led to the development of a portable device able to spot antibiotic resistant bacteria. This should help with more precise drug targeting and potentially save lives.

We also look at how social science is helping to improve the health of people reliant on woodstoves for cooking, and we unearth a huge impact crater hidden in plain sight.

Cancer is the second leading cause of death in the world. Many of us will at some point in our lives be confronted with the disease – either by falling ill ourselves or through a family member or friend. For CrowdScience presenter Marnie Chesterton, the diagnosis would change her life.

The range of cancer symptoms and mortality rates vary considerably. Not all cancers are fatal and in some cases, cancer ends up more like a chronic debilitating disease, resulting in patients eventually dying from some other condition. This has got listener Gill in Scotland wondering – why do we call all cancers, cancer? And when did doctors first realise that all cancers are part of the same problem?

First described by the Egyptians thousands of years ago and later coined by the Greek physician Hippocrates as “karninos”, the Greek word for “crab”, cancer is ominously absent from medical literature until the late 19th century. Throughout history it has puzzled, infuriated and enticed doctors and scientists to push medical science to its breaking point. Archaeologists have recently discovered that the ancient Egyptians had a term for cancer and that remedies they used then contain compounds that are found in modern chemotherapy.

As we uncover the science and history of cancer, presenter Marnie Chesterton takes us on a journey through her own experience of living with and beyond the diagnosis and we examine the promise of future treatments.
