Rewilding is a conservation approach based on the reintroduction of lost animal species to their natural habitats. Its original manifestation was controversial because it centred on apex predators like wolves. But the approach has matured and advocates believe it now has a crucial role to play in securing future biodiversity levels.

Some animals, like sea sponges, can live for hundreds, perhaps thousands of years. They also never get cancer. Understanding why that’s the case has led scientists to question conventional notions of ageing. The idea that future humans may never grow old now seems theoretically possible.

Most of us are healthier, wealthier and better educated than ever before. We have greater access to knowledge and expertise than any previous generation. So, why do humans keep doing stupid things? And why is the world awash with conspiracy? Have we already passed “peak intelligence”? And if so, what can we do to ensure a smarter future?

There’s been a huge increase in the number of satellites orbiting Earth with private companies and governments planning to launch hundreds more. Near-Earth orbit is already crowded, and the risks posed by space junk are increasing. The consequences could be catastrophic.

Scientists in the UK have developed a form of artificial intelligence that mimics the brain functions of a honeybee. The results promise to make drones and other flying craft far more manoeuvrable and crash-proof. Also, the dream of a “female internet”; and why mathematician, Hannah Fry, thinks all technologists should take a Hippocratic oath.

Stories like opinions have become a necessity of modern life.  Everybody is encouraged to have an opinion and everybody – in the vernacular of countless motivation speakers – is encouraged to be the “hero of their own story”. But are we in danger of making too much of them? If the story becomes the central device for much of our communication, do we risk losing our sense of objective reality? 

Sovereign Wealth Funds come in all shapes and sizes. They act as government-backed investment vehicles. They’re used to fund specific social projects and to act as a nest-egg for future generations. There are currently around 150 in the world with global assets worth in excess of $USD 9 trillion. But are they worth the investment?

Imagine if you could use your own body heat to recharge your smart phone? That’s just one of the ways scientists are trying to decentralise energy production. They also have an eye on new means of power distribution, including using laser beams instead of lines and poles.

There’s a serious campaign underway to have 30 per cent of the Earth designated as a giant conservation zone. The target date is 2030.

The eventual aim is to lock down half the planet. It’s about protecting habitats and biodiversity.

But, in so doing, what are the risks for indigenous communities and the poor?  

How many private details are you revealing online – and how valuable is that information? And more importantly what steps can you take to protect your data?
