Host Maddie Sofia and reporter Emily Kwong evaluate what truth there is to the popular phrases "blind as a bat" and "memory of a goldfish." Hint: The phrases probably weren't born out of peer-reviewed science. Tweet Maddie at @maddie_sofia and Emily at @emilykwong1234.

2019 was Australia’s hottest year on record, a major factor behind the bush fires which have been far worse than usual. We look at the patterns of extreme weather that have contributed to the fires but are also linked to floods in Africa. And the way in which thunderstorms have helped to spread the fires.

The armpit of Orion is changing. The star Betelgeuse is dimming some claim this is readying it for a major explosion others are more sceptical, we weight up the arguments.

And an Iron Age brain may hold some clues to modern neurodegenerative disease. Protein fragments have been extracted from the brain tissue found inside a 2,500 year old human skull.

It's called silicosis, and it's been known about for decades. So why is it now emerging in new numbers among workers who cut kitchen countertops? NPR science correspondent Nell Greenfieldboyce explains. More of her original reporting on silicosis is here. Follow host Maddie Sofia on Twitter @maddie_sofia. Email the show at shortwave@npr.org.

Biologist Lesley Hughes from Macquarie University in Australia explains why the recent bushfires there could change the country forever. Hughes is a former federal climate commissioner, and has been the lead author on two reports for the UN's Intergovernmental Panel on Climate Change. Follow host Maddie Sofia on Twitter @maddie_sofia.

With each new year comes a wave of good intentions as people aim to be better. They want to lose weight, exercise more, be nicer, drink less and smoke not at all. They want to change behavior, and as Susan Michie knows well, “behavior is related to absolutely everything in life.”

Michie is a clinical and health psychologist who leads the Centre for Behaviour Change at University College London. She specializes in behavior related to health – for behavior or health practitioners, patients and population as a whole – and in looking at how behavior impacts the natural environment. And while you might think that the essentials of human behavior are pretty similar, one of the things Michie quickly tells interviewer Dave Edmonds in this Social Science Bites podcast is that it can be unwise to jump to conclusions when studying behavior (or trying to change it).

She notes, for example, that lots of behavioral research is done in North America, where there’s relatively abundant funding for studies, “but the biggest need [for research] is often where there’s the least investment. There’s no point in developing an intervention based on research evidence conducted in parts of the world that are very far away from the type of context we want to implement the findings in – only to find out it’s not going to work.”

So yes, she says, do look at both the rigour of the research, but also base any potential application of the findings on deep understanding of local conditions and using local knowledge.

Michie and her team describe this using a model, COM B, to account for the ‘capability, ‘opportunity’ and ‘motivation’ necessary to change behavior.

Changing behaviors is important – “In order to solve any of these big social challenges we need people at different positions in society to change their behavior” -- so these considerations matter. But that begs the questions of what behaviors need changing – and who decides what those selected behaviors are..

“There’s a big issue about who decides what the key issues are,” Michie says. “But I think there are certain problems which are very self-evident – there are people dying unnecessarily as a result of smoking, obesity but also environmental conditions – poor housing, etc. There are areas where the social consensus is that things needs to change, and I’d say those are the ones we start with.”

In the interview, Michie also addresses the ethics of behavior change and how algorithms and machine learning will be “absolutely vital” to parse through all the relevant data . Her own Human Behaviour Change Project is a collaboration between behavioral scientists and computer scientists combing the global literature to see what works, with an initial focus on smoking cessation. A comprehensive tobacco control strategy, she details, involves those infamous “nudges” beloved of policy makers, but also the legislation, services and taxation, that need to work synergistically to effect real change.

Michie had a long career as a research fellow and clinician before joining the Psychology Department of University College London in 2002. She’s a fellow of the Academy of Medical Sciences, the Academy of Social Sciences, the Academy of Behavioral Medicine Research, the Society of Behavioral Medicine, the European Health Psychology Society, the British Psychological Society and a Distinguished International Affiliate of the American Psychological Association. 

Some dairy farmers in Massachusetts are using food waste and manure to create renewable energy. Each farm produces enough to power about 1,500 homes. Not only does this process create electricity, NPR Science Correspondent Allison Aubrey tells us it also prevents the release of methane, a greenhouse gas.

Okay, it wouldn't technically be an explosion. And if it's "about" to happen, it already happened. About 650 years ago.

Roland Pease is joined by California based science Journalist Molly Bentley as we examine the impact of earthquakes and fires. California has experienced both in the last year - What’s it like to live with a constant threat from these extreme events? We also take a look at NASA’s plans for a new mission to Mars – to look for signs on life.

What is empathy? This week’s question comes from Maria in Amsterdam who has noticed that when one of her friends is in pain, she feels their pain too, literally. Maria wants to know - is she experiencing a type of ‘super’ empathy?

To help find the answer, Marnie Chesterton visits the Netherlands Institute for Neuroscience and gets into an MRI scanner to discover what is happening in her brain when she empathises.

She talks with a pro-social psychopath to find out how psychopaths experience empathy differently and how they navigate social situations.

And Marnie meets with a mediator specialising in The Israeli–Palestinian conflict, to learn the value of empathy when the stakes are at their highest.
