Austrian archaeologist, Immo Trinks, has a grand ambition – to map the entire landscape of Europe, below ground! The 3D scanning technology he's using won't just uncover hidden archaeological treasures, it can also be used to check below our cities and major transportation routes for geological faults. Also, why mucking about with subatomic particles could help scientists develop a form of underground GPS.

Amazon now feels more like a racket than an open shopping platform; you can't find posts from your friends on Facebook because it's clogged with unsolicited advertising; and Uber no longer seems like a cool, efficient taxi service, it's morphed instead into a global machine for turning gig workers into the new underclass – it's all part of a process Cory Doctorow has dubbed "enshittification". In this feature interview, the Canadian sci-fi author, journalist and digital rights activist...

Advanced Artificial Intelligence and new digital technologies are revolutionising the architectural industry. Architects in Brisbane, for example, have mapped every millimetre of historic Lamb House using a 3D scanner – inside and out – and the speed and accuracy of their modelling saves money and prevents error. The opportunities for creativity are enormous, particularly where AI is concerned. But is the industry inadvertently making itself redundant?

Science and technology cannot solve our most challenging and complex environmental problems. At least not on their own, not without a greater emphasis on person-to-person engagement — people working together across knowledge systems. ABC Top 5 Science Media Resident, Dr Rohan Fisher, says sci-tech too often avoids the difficult, social-political and cultural dimensions. Human-generated problems require human-centric solutions, he argues. In this episode we explore how to utilise tech and...

The Chinese Government, and its Central Bank, are currently experimenting with a digital currency. The hope is that it will make financial transactions faster, more efficient and cheaper for government, business and ordinary citizens. Some speculate it's about giving China's currency an edge over the PRC's major economic competitor, the United States. But whether Beijing's experiment succeeds or not will depend on matters of trust, surveillance and international appeal.

It's only a matter of time before people start worshipping Artificial Intelligence as a religion, that's what Philosopher and ethicist, Neil McArthur, believes. And he says while the emergence of AI-based religion would carry risks, there's no basis for discriminating between AI-based religions and more established ones. Also, why artists are sending their creations into the heavens and what makes for good "space art".

"Geoeconomic confrontation" ranks as one of the most severe risks facing the world, according to a recent World Economic Forum report. Trade is increasingly becoming a weapon of warfare, and the future consequences for world co-operation could be significant. So, should the use of sanctions be regulated by an international body? And if a global regulator was established would it have teeth?

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.

Have technologists lost the art of keeping it simple? Do the devices they design actually make our lives more complicated, not less? Striving for simplicity could positively impact many aspects of modern life. But oversimplification risks stereotyping individuals and confusing our sense of historical perspective.

Much of the way we think about the economy and our environment is based on a linear model – a system of extraction, consumption and waste. But advocates for a "circular economy" approach argue it's time to start mimicking the cycles of nature that keep the planet healthy. It's about seeing waste as a resource and thinking about the future impact of today's decisions. It's a noble idea, but is it realistic?

Authorities in New York city are planning to introduce a congestion pricing scheme. Vehicles entering certain parts of Manhattan will soon have to pay for the right to do so. Proponents of such schemes say they help reduce traffic, improve air quality, and can boost public transport patronage and funding. But from the experience of other cities around the world, vested interests and partisan politics can prove a stumbling block. So, what measures work best and how do you ensure social and...

It's time to rethink what we mean by productivity, says work futurist, Dominic Price. What's important isn't output, but outcomes. And confusing the two, he says, is simply counter-productive! Also, benefit corporations — why many businesses are moving away from an obsession with profit at all cost; And why a compulsory savings model could help control inflation without raising interest rates.

Scientists are experimenting with sound to try and lure seabirds back to depleted environments. But not just any sounds – we're talking about the coos and calls associated with breeding. It's all part of an ecological approach called Acoustic Restoration and its already having an impact on Palmyra Atoll – a remote island halfway between Hawaii and American Samoa. It's hoped the acoustic approach can revive many different kinds of ecosystems, even after natural disasters — when nothing is...

Around two billion air conditioners are currently in use across the globe but the amount of electricity they use is not sustainable, so what are some alternatives?

Chatbots and other forms of interactive AI aren't just shaping our online preferences, they're gradually redefining the contours of what we mean by love, sexuality and intimacy. Sociologist Anthony Elliott warns the impacts will be society-wide, not just personal. Also, do we need a set of general principles for managing chatbot liability in the absence of regulation? And how the rights of children are being overlooked in the hyper-contructed world of the "momfluencer".

Why do otherwise sensible people continue to do things that are bad for them, that impact negatively on their personal future? Also, what happens in the brain when you're trying to make or break a habit?  Temptation, addiction and habit formation – mapping the pathways to self-destruction and how to navigate a better course. 

2023 could be the year we finally reach a tipping point in the fight against climate change. The energy think-tank Ember predicts global greenhouse gas emissions in the energy sector (which accounts for 30% of global emissions) are finally on the way down. Also, a tipping point of a very different kind – experimentation in neuro-technology is now so advanced that ethicist Nita Farahany believes companies and governments will soon be trawling our thoughts the way they currently trawl our...

Exploring new ideas, new approaches, new technologies — the edge of change.

Exploring new ideas, new approaches, new technologies — the edge of change.

Japan has long prided itself on its pacifist constitution. The country's future after WW II was defined by Article 9 which famously denounced aggression. But, in recent years security has become a paramount concern with increasing tensions around the status of nearby Taiwan and challenges from neighbouring countries. The Japanese are now renegotiating how best to defend themselves and their interests, while holding true to constitutional restraint. What that could mean for the future of Japan...

Global permission to mine the ocean floor — the International Seabed Authority will soon meet and decide whether or not to allow seabed exploitation, and in what circumstances. We'll hear the arguments both for and against and get some background on this little known, but hugely consequential, international regulatory body. Also, will advanced technology one day make the oceans transparent? And if so, what will that mean for the future of submarines – a technology that relies on stealth and...

How best to build our homes so they can better withstand natural disasters? It's not just about designing for floods or fire, for example, but creating structures to withstand multiple threats. And to cope with any change of temperature on top of that? Many countries are facing an increase in climate-related threats, and they're struggling to cope and adapt. In Australia, a review of the National Construction Code is underway and there are calls for higher minimum standards. Should such a...

Robobees and building more hives – there's no easy solution to the global decline in bee population numbers and associated problems with pollination. Scientists around the world are seeking a better understanding of bee behaviour and how it can be modified. Their efforts involve using micro robotics to pamper the Queen bee and to improve the insect environment. A mix of the sophisticated and the very simple.
