A critical look at new technologies, new approaches and new ways of thinking, from politics to media to environmental sustainability.

Future Tense

Methane levels are going up — not down, despite decades spent trying to reduce emissions from agriculture and landfill. But some countries are bucking the trend, we find out who and how.

Breeding sheep and cattle to burp less is one way to reduce methane emissions. ABC Top 5 Science Residency recipient Luisa Olmo talks us through a genetic selection programme that could lead the way forward.

Most people want to eat better. And many of us have embraced the trend toward "natural" foods and conscious eating.

We equate "natural" with healthy, nutritious and virtuous, but that can often be way off the mark. New research shows many healthy alternatives are anything but. And our embrace of the term natural is more about expressing identity and morality rather than healthy eating. Empowering people to understand what and how they should eat is what it should be about – and one way to do that is by using a food labelling app.

Nostalgia triggers our emotions and that in turn makes us vulnerable to manipulation. We speak with Richard King about the commodification and weaponisation of nostalgic sentiment. Also, New York Times critic-at-large, Jason Farago, on why he believes our cultural age might be the least innovative in half a millennium.

Algorithmic feeds are meant to personalise our online experiences, but increasingly they're flattening our culture and fostering a dull conformity, according to best-selling author Kyle Chayka. And the influence they exert on our lives is increasingly physical not just digital. Also, data scientist Gloria Mark who has crunched the numbers on how our attention spans have fared over the past decade or so. If you can keep focused, you might find it fascinating.

In our uber-connected world, the development and management of really anything is becoming increasingly complex. Planning for the future has to involve more than just grand ambitions, it also needs to be alert to unintended consequences. Otherwise things you didn't even dream about will go wrong and that can prove enormously costly. Part of the solution is to think past the immediate and adopt a systematic approach to thinking.

Authoritarians rule through fear. We can clearly see that from China to the Middle East to eastern Europe. But why do we constantly overlook the way in which fear also shapes democratic societies? It's fueling populism and distorting our future focus. Then there's anger. It's inspired generations to man the barricades and right society's wrongs. But anger is increasingly becoming a driver of commerce. There's billions to be made in getting you riled up and keeping you that way. Fear fuels anger, and anger blinds you to recognise that your fear might be misguided. A truly vicious cycle.

The vicious cycle of fear and anger — and how it traps society

Privatising public services like trains, hospitals or prisons — is a proven vote loser. But governments of both the left and right continue to privatise — when it suits them. And it suits them, it seems, when large sums of money are needed to pay down debt, or when a government seeks to off load risk and liability to the private sector. So, what conditions should be applied to ensure that privatisations truly serve the public interest and don't simply decrease competition?

Why does Utopian thinking get such a bad rap? It’s often derided as delusional and dangerous. But what if that stereotype is designed to limit our imagination and choices? We hear often that people are tired of democracy and turned off by short-term political thinking. So, is it time to be much more adventurous and ambitious – dare we say utopian – in our imagining of the future?

Terms like "Gen Z", "Boomer" and "Millennial" are popular, but they have no basis in science. Demographers and social scientists are now pushing back. Generational labelling, they argue, is akin to Astrology and while politicians, journalists and media influencers find them irresistible, they actually promote pseudo-science, sew social division and can reinforce prejudicial stereotypes. So why are generational labels so popular?

A series of massive underground tombs for nuclear waste are currently under construction. They've taken decades to plan and build and they're designed to house the world's nuclear waste for millennia to come. So where are they being built? How safe will they be? And how to devise a toxic waste warning sign that will make sense to people living tens of thousands of years from now?

Also, the latest research on how climate change is beginning to impact on internal migration within countries.

NASA's new telescope will revolutionise the search for non-Earth based life. It's to be called the Habitable Worlds Observatory and will be powerful enough to peer into the atmosphere of planets outside of our solar system.

But if, or when, we do find evidence of a life form beyond our solar system what do we do next? And who should decide whether or even how we make contact? A new research hub at the University of Andrews is among those drawing up a plan.
