Covid- 19 cases seem to be multiplying daily and there is now a growing body of scientific evidence both on its spread and the effectiveness of measures to try and control it. We look at what’s working, what’s not and why.

And we look to the potential for coronavirus drug treatments, why despite the hype there really isn’t anything round the corner.

Australia’s recent fire season was intense; a new study looks back over 500 years of the weather pattern partly responsible, the Indian Ocean Dipole. The findings show the most extreme years occurred recently – under the influence of man-made climate change.

And we look at life deep below the sea floor, microbes which multiply slowly over centuries and eat their neighbours.

Coronavirus is all over the headlines. Accompanying the growing anxiety around its spread, has been suspicion and harassment of Asians and Asian Americans. For more on this, we turned to Gene Demby, co-host of NPR's Code Switch podcast, and his conversation with historian Erika Lee. We talk about how this wave of stigma is part of a longer history in the United States of camouflaging xenophobia as public health and hygiene concerns.

Physicists have done the math and there should be as much antimatter as matter — but that hasn't been the case so far. NPR Correspondent Geoff Brumfiel explains what's up with matter's "evil twin," antimatter.

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.

And 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?

From currency and commerce, food labels to laboratories, the metric system is the foundation of many science and math fields. To mark our 100th episode (a multiple of 10, which is the basis for the metric system!), we spoke with Elizabeth Benham, Metric Program Coordinator at the National Institute of Standards and Technology, about the presence of the metric system in our everyday lives.
