Getting the general public to monitor local plants and animals could help paint a clearer picture of the global biodiversity crisis, but fundamental social change is needed if we are to reverse the loss of nature critical to our survival, say biodiversity experts.
Shifting people to a new diet that is healthier for both the planet and for our bodies will require radical changes in the way food is grown, sold and eaten, including possibly adding a tax on meat and dairy products.
With Europe facing significant challenges over the next decade, it is vital that the EU’s research activities are designed not just by bureaucrats but by a wide range of voices to ensure that they’re fit for purpose, according to Jean-Eric Paquet, the European Commission's Director General for Research and Innovation.
On December 17th, the European Space Agency’s CHEOPS telescope will blast into space to take a closer look at some of the potentially habitable planets we’ve found beyond our solar system. Ahead of its launch, Horizon takes an in-depth look at what we already know about such exoplanets and what’s still to learn. We speak to Dr Michaël Gillon, who in 2017 was instrumental in discovering a system of seven Earth-like planets outside our solar system, about the diversity of the thousands of exoplanets we’ve found so far and next steps for research. We talk to scientists who are trying to understand the structure of Super-Earths – planets up to 10 times the size of Earth – by recreating elements of planetary cores in their labs, and others who are trying to understand how different planetary systems formed in the first place. Finally, we delve into one of the most important conditions for life to exist on exoplanets – their atmospheres – and find out how scientists are trying detect the biosignature gases that indicate the presence of life.
All over the world, bacteria are becoming resistant to antibiotics, making infections more difficult – and in some cases impossible – to treat. It’s one of today’s biggest public health challenges and this month Horizon examines how scientists are working to overcome this growing issue. We speak to microbiologist Dr Nassos Typas about how we got here, what causes resistance to antibiotics and the different approaches being explored to combat resistance. We look at renewed efforts to find new antibiotics and ask whether it’s possible to reverse antibiotic resistance. And with dairy being a huge food source and also an antibiotic-intensive industry, we speak to scientists who are developing alternative therapies for treating cows for mastitis as a way of curbing antibiotics from coursing through our food chain.
As our world becomes more digitalised and connected, we can actually make a virtual copy of it. And such replicas are now being used to improve real world scenarios, from making aircraft production more accurate to preventing oil spills.
Consciousness – the awareness we have of our self and surroundings – is often referred to as ‘the hard problem’. It’s not easy to scientifically explain how a subjective experience, which is something intangible, can be created by the brain – a physical object. But understanding more about how consciousness works could help us find treatments when things go wrong.
Virtual simulations can also help build aeroplane wings more efficiently.
Understanding consciousness in healthy people could help when things go wrong.
