Why are we obsessed with crime? Kay from Hamburg, Germany asks as every Sunday evening Germans pile into their local pubs to watch Tatort, a hugely successful crime drama which has been running for 50 years.
Presenter Marnie Chesterton starts with the science and speaks with psychologists to get to the bottom of where this obsession might come from. Have we evolved to have an innate obsession with danger or are we addicted to feeling fear?
Or perhaps the dramatisation of crime fuels our obsession. Producer Caroline Steel visits the film set of BBC crime drama, Line of Duty. Producer Jed Mercurio explains what draws us to crime narratives and the techniques he uses to keep his audience captivated.
But does the way we chose to represent crime in media match up with reality? And what is the impact of this on society and policy?
Attributing Australia's bush fires, a major study says man-made climate change was a big driver – making the fires at least 30% worse than they would have been if natural processes were the only factors.
We look at preparations for coronavirus in Africa. Although cases there are currently lower than in much of the rest of the world a major training initiative is taking place to spread awareness amongst medics across the continent.
We ask why Horseshoe bats in particular carry coronaviruses, and find a novel idea for distributing vaccines in places without refrigeration.

Johannes Gutenberg's printing press changed the course of human history. It created a new way of doing business, drastically reduced the cost and speed of making books, and enabled texts, ideas and arguments to spread further and faster than ever before. So why did he struggle to make money from it?
The appearance of Covid -19 in Italy and Iran surprised many this week. As the virus continues to spread we look at ways to contain it.
Australia’s fires have burnt around 20 percent of the countries woodlands, what are the implications for the recovery of those ecosystems?
And what is the link between the world’s super rich and deforestation? Unsurprisingly it’s money.
And we hear about the unexpected cooling effects of hydroelectric dams.
Weather: wet, dry, cold, hot, sunny, windy or downright weird - there’s nothing quite like it as a conversation starter, from Austin to Jakarta. And judging from the large volume of emails about all things meteorological in the CrowdScience inbox, there’s plenty to talk about.
What’s the weirdest weather on Earth, and how big a chance is there of it happening? Why does it always seem to rain on the days when we’re not working? And – conversely – is there any way we could make it rain when and where we need it to? Presenter Anand Jagatia finds out the answers to these questions and more by bringing together a panel of experts under the CrowdScience umbrella: Prof Liz Bentley, Royal Meteorological Society; Dr Anthony Rea, World Meteorological Organization, and Dr Rebecca Buccholz, National Centre for Atmospheric Research.

First developed by a toy company in the 1890s, slot machines have become one of the most profitable tools of the gambling trade - but many who play them say winning isn't the point. So why can't people pull themselves away? Tim Harford looks under the spinning wheels and flashing lights to see what these devices reveal about the business of addiction.
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.

In 1997, Garry Kasparov, widely regarded as the world's greatest chess player, was defeated by Deep Blue, a computer. But how much did that reveal about the 'brainpower' of machines? Tim Harford explains by delving into the history of algorithms. They've been used by mathematicians and scientists for millennia, but have acquired a new level of power and importance in the digital age.
