Liquid water on Mars, athletic performance in transgender women, and the lost colony of Roanoke
Billions of years ago, Mars probably hosted many water features: streams, rivers, gullies, etc. But until recently, water detected on the Red Planet was either locked up in ice or flitting about as a gas in the atmosphere. Now, researchers analyzing radar data from the Mars Express mission have found evidence for an enormous salty lake under the southern polar ice cap of Mars. Daniel Clery joins host Sarah Crespi to discuss how the water was found and how it can still be liquid—despite temperatures and pressures typically inhospitable to water in its liquid form.
Read the research.

Darknet Opioids
When tackling societal problems - like the opioid epidemic in the US - there are two ways of approaching it. One is to reduce demand - by organising treatment programmes, or reducing the underlying reasons why people may become addicted in the first place - but that ’s hard. So governments often turn to the other route - reducing supply - and that’s what the US government did in 2014 when it rescheduled oxycodone combination products from schedule 3 to schedual 2 - essentially making it harder for people to obtain a prescription.
Now reducing that legal supply, without in hand reducing the demand, led to fears that ...

Drug use in the ancient world, and what will happen to plants as carbon dioxide levels increase
Armed with new data, archaeologists are revealing that mind-altering drugs were present at the dawn of the first complex societies some 5000 years ago in the ancient Middle East. Contributing writer Andrew Lawler joins Sarah Crespi to discuss the evidence for these drugs and how they might have impacted early societies and beliefs. Sarah also interviews Sarah Hobbie of the University of Minnesota about the fate of plants under climate change. Will all that extra carbon dioxide in the air be good for certain types of flora? A 20-year long study published this week in Science suggests theoretical predictions have been off th...

Interventions to increase attendance for diabetic retinopathy screening
As well as the problems with blood sugar control that are caused by diabetes, the condition can lead to a variety of other problems. One of these is an eye problem called diabetic retinopathy and it ’s important that people with diabetes are checked for this. A January 2018 Cochrane Review looks at how to increase attendance at these screening visits and lead author, John Lawrenson from the City University of London in the UK, tells us more in this podcast.

Accuracy of different non-invasive methods for identifying Helicobacter pylori
Cochrane Diagnostic Test Accuracy reviews bring together the evidence that should help practitioners to choose the most appropriate way to diagnose an illness or condition. This is now the case for the stomach bug, Helicobacter pylori, and we asked Lawrence Best from the UCL Medical School in London England to tell us about the findings of this March 2018 review.
