The hyperloop is what you get when you take a magnetic levitation train and put it into an airless tube. The lack of resistance allows the train, in theory, to achieve unseen speeds, a concept that is edging closer and closer to reality – and could provide a greener alternative to short-haul air travel.
Picture yourself speeding down the highway with no hands on the wheel, checking your emails while your car takes care of responding to what’s happening on the road. Would you trust your car to make the right decisions? If you have doubts, you’re not alone.
Asteroids can pose a threat to life on Earth but are also a valuable source of resources to make fuel or water to aid deep space exploration. Devoid of geological and atmospheric processes, these space rocks provide a window onto the evolution of the solar system. But to really understand their secrets, scientists must know what’s inside them.
In January 2021, Storm Christoph pummelled the United Kingdom with heavy rains and the threat of unmanageable runoff. But in flood-prone Manchester, a newly developed park was proving its worth.
Ships have a significant environmental impact during building, operation and when they’re scrapped, but new approaches and composite materials to replace steel – still popular due to its strength and low cost – could make vessels more sustainable, recyclable, and less noisy for marine animals.
There are a lot of things that pose a threat to our planet – climate change, natural disasters, and solar flares, for example. But one threat in particular often captures public imagination, finding itself popularised in books and films and regularly generating alarming headlines: asteroids.
The successful development of mRNA vaccines for Covid-19 is ‘transformational’ and opens the doors to new types of vaccines for other infectious diseases as well as cancer, according to Dr Özlem Türeci and Dr Uğur Şahin, the co-founders of Germany’s BioNTech.
The speed with which coronavirus vaccines have been developed surprised everyone and could transform public health into the future, says Dr Fergus Sweeney, head of the clinical studies and manufacturing taskforce at the European Medicines Agency (EMA). Here he gives us a glimpse at the work of the regulator over the past year as part of the fight against Covid-19.
The asteroids in our solar system are the remnants of planetary formation. They hold clues about how the Milky Way formed, but they also hold promise and peril for humans as the source of both rich materials and potentially dangerous cratering events. This month we look at the latest in asteroid research. We speak to Dr Naomi Murdoch, a planetary scientist, about her work investigating asteroids, how to land on them and how to defend Earth from a dangerous event. We look in depth at how scientists in the field of planetary defence are developing rapid response techniques to detect an Earth-bound ‘imminent impactor’, determine within days whether it’s dangerous, and evacuate people from the danger zone. We speak to scientists studying exactly what asteroids are composed of so that we can categorise them from Earth, and we look at work studying asteroid dust to see what it can tell us about the early days of our solar system and the origins of life on our planet.
Asteroids — the bits and pieces left over from the formation of the inner planets — are a source of great curiosity for those keen to learn about the building blocks of our solar system, and to probe the chemistry of life.
Hyperloops could replace short-haul air travel.
Car manufacturers are rolling out higher levels of automation but public acceptance is lagging behind.
Dr Kate Rychert studies ocean plate structures.
