This year’s Atlantic hurricane season has seen a new record for severe storms says Climatologist Michael Mann. He says warming oceans are one of the drivers.

And Australia has seen spring temperatures hit new highs. Climate scientist Sarah Perkins – Kirkpatrick says it’s all the more remarkable as weather patterns are currently in a cycle associated with cooler temperatures.

Where exactly did SARS- COV-2 emerge from? That’s one of the questions for a WHO fact-finding mission to China looking into the origins of the Virus. Peter Daszak has worked with Chinese scientists for many years, looking for bat viruses with the potential to jump to humans. He tells us how the mission hopes to map out the event which led to the initial spread of the virus.

And the Japanese Hayabusa2 space probe is due to return to earth. Masaki Fujimoto Deputy director of the Japanese Space Agency JAXA, tell us what to expect when a cargo of material from a distant asteroid lands in the Australian desert.

Like many states in the Midwest, Nebraska was somewhat spared during the early days of the pandemic. But now, the state has more cases per capita than any other in the country. We talk with two Omaha doctors who say this latest surge is exhausting health care workers, and one explains why she's tired of people calling health care workers heroes.

Forensic psychologist Belinda Winder, who founded and heads the Sexual Offences, Crime and Misconduct Research Unit at Nottingham Trent University, wants society to understand one key aspect about pedophilia. “Many people understand pedophilia to be both a sexual attraction to children but also the act of committing abuse against children,” she explains to interviewer David Edmonds in this Social Science Bites podcast. “And that’s wrong.” Those are two different things, she continues.

“Pedophilia is sexual attraction – enduring and sustained sexual attraction. Not something that someone wakes up with one day, but something that people have come to realize, sometimes over many months, that they have a sexual attraction, maybe a sexual preference, for pre-pubescent children.”

Of course sexual abuse against children does occur, and Winder explains that’s not pedophilia but pedophilic disorder, “where someone acts on their interests.” The disorder also covers the significant mental difficulty, such as guilt or embarrassment, that having this attraction may cause. (And it’s worth noting that Winder reports that more than half of the people convicted of committing sexual abuse against pre-pubescent children are not pedophilic.)

Winder’s research, conducted in the United Kingdom, United States, Canada, Australia and New Zealand, shows this distinction between urge and action matters greatly for addressing pedophilia. This is especially true in an environment where its merest whiff results in instant condemnation – and where the angry ornaments of that condemnation serve none of the victims of pedophilic disorder, whether the children or the offender.

“Until we as a society can see there is a difference between a sexual preference for children which we cannot change and cannot do anything about and we did not choose, versus committing sex abuse against a child — which absolutely people should take responsibility for, which they do have control over and which they can change — then I think the world is going to be quite a difficult place for anyone who wants to step forward and say, ‘This is me, what a most unfortunate sexual orientation to have.’”

That awareness helps in therapies that have been shown to successfully address pedophilic disorder offenders. “It’s taking the blame for the preference and the interest from people but putting the responsibility for their behavior squarely back with the person.”

Winder set up the Sexual Offences, Crime and Misconduct Research Unit in 2007 to build upon the collaborative relationship between Nottingham Trent’s Psychology Department and the British prison Whatton, one of Europe’s largest sex offender prisons with more than 830 convicted male sex offenders housed there. She is also co-founder, trustee, vice chair and head of research and evaluation for the 6-year-old Safer Living Foundation, a charity that conducts and evaluates initiatives that help to prevent further victims of sexual crime.

In this podcast Winder discusses the prevalence of pedophilia, how it can be viewed as a sexual orientation, and what responses work – and which don’t – in addressing the disorder. On the latter, Winder sees some popular responses to offenses as ineffective at best and harmful at worst.  Imprisonment, Winder says, is appropriate for the crime but does little to deal with the underpinnings of why people committed child sex offenses.

But some of the programs set up to address those underpinnings, like Britain’s former Sex Offender Treatment Programme, don’t work. “[SOTP] was carefully evaluated and some of the aspects of that which really didn’t seem to work at all was the idea that we needed to encourage more empathy in people, the idea that empathy was important – if we encourage more empathy then people wouldn’t offend – that’s just too simplistic and has not been shown to work. Part of the SOTP was getting people to go through every minutiae of what they had done and the offense they had committed, and again, I think that’s more to encourage shame, and shame can be very counterproductive. If you are dwelling in a pool of shame, then it may be you feel you are beyond saving.”

Exclusion also doesn’t help, which is why Winder has a special scorn for sex-offender registries, which she calls “actively ineffective." "If what you need is to connect with other people – this is what helps you not offend again in the future. … Once you’ve been brought to task for your sexual offending you are highly unlikely to commit another one. But the thing that might push you to re-offending is not having people to talk to, not having a place to stay. So really we need to allow people to resettle.”

Some of the most popular agricultural biotech products are running into problems. These plants have been genetically modified to fend off insects, and have been great for the environment and for farmers. But now they are not working as well. NPR food and agriculture correspondent Dan Charles explains the rise and potential fall of Bt crops, and what happens when farmers use too much of a good thing.

The National Science Foundation recently announced it plans to decommission the Arecibo Telescope in Puerto Rico. The world-renowned telescope has suffered substantial damage this year. Today, we revisit our conversation with planetary scientist Edgard Rivera-Valentín about the unique role Arecibo has played in both scientific research and popular culture. (Encore episode.)

While developing new treatments drug companies usually release little useful information on how the clinical trials are progressing. However with the world’s attention on potential vaccines against Covid -19, the usually dull data on the progression of each trial step is subject to huge scrutiny. It doesn’t help to clarify things says epidemiologist Nicole Basta when that data raises questions about the rigour of the trial itself. This seems to be what happened with the latest Astra Zeneca, and Oxford University trial – where the best results were reportedly due to a mistake.

The link between locust plagues and extreme weather was demonstrated once again when cyclone Gati hit Somalia – dumping 2 years worth of rain in just a few days. This creates a perfect environment for locusts to breed to plague proportions. And this will be the third time in as many years that cyclones will trigger such an effect says Keith Cressman from the UNFAO. However thanks to the previous recent locust plagues in East Africa the countries most in line for this returning locust storm are better prepared this time.

A study of tree rings from Greater Mongolia suggests the region is now drying out rapidly, the past 20 years have been drier than the past thousand says climate scientist Hans Liderholm. This points to potential desertification in coming years.

And the death of a scientific icon. The Arecibo observatory, featured in the films ‘Goldeneye’ and ‘Contact’, and responsible for the Nobel Prize winning detection of gravitational waves is facing demolition. Sitting in a crater in the jungles of Puerto Rico this 57 year old radio telescope dish has suffered severe storm damage and is in danger of collapse. Astronomer Anne Virkki, who works at the telescope and science writer Shannon Stirone explain its significance.

This year, dramatic wildfires wreaked havoc across the globe from Australia to Siberia. CrowdScience listener Melissa wants to know the extent to which climate change is a factor in blazes that appear to be increasing in both frequency and intensity.

Presenter Anand Jagatia hears how scientists use alternative worlds in computer models, to understand the role that global warming plays. After Siberia’s hottest ever year on record, he discovers the impact of increasing temperatures on boreal forests – and how they could help release huge stocks of carbon that has been stored in the soil. But is there anything we can do to prevent this happening? He visits the UK’s Peak District region, where conservationists are re-wilding a massive area with a special species of moss, which may offer a solution to an increase in infernos.
