From a chemical-free spray that turns sand into lush green land, to a caterer who serves planet-friendly dishes, and from technology that makes stronger concrete with less cement, to insect farms that produce fish food and fertilisers, there is no shortage of ideas to reduce emissions. But which ones work best?
When you hear the word ‘quantum’, you may imagine physicists working on a new ground breaking theory. Or perhaps you’ve read about quantum computers and how they might change the world. But one lesser-known field is also starting to reap the benefits of the quantum realm – medicine.
A new, digital revolution might be about to hit us. Autonomous cars are driving our way, cities and companies are rapidly ramping up the use of sensors – also called the Internet of Things (IoT) – and virtual and augmented reality are making rapid strides.
A few summers ago, Stefano Piraino was walking along the rocky shoreline on a small island off the coast of Sicily when he spotted a washed up jellyfish. Naturally, he tore a piece off and popped it into his mouth.
A powerful new form of computing could help scientists design new types of materials for nanoelectronics, allow airlines to solve complex logistical problems to ensure flights run on time, and tackle traffic jams to keep cars flowing more freely on busy roads.
Blending biofuels and kerosene to create greener jet fuel has shown promising results in test flights, but more work needs to be done to ensure biofuels burn cleanly and can be produced in a large-scale, low-cost way, says Dr Chong Cheng Tung, associate professor at the China-UK Low Carbon College of Shanghai Jiao Tong University in China.
Small farms sometimes get overlooked as a feasible solution for feeding a growing population, but researchers say they should be given greater support, with some producing more food than official statistics report.
Quantum computers pose a big threat to the security of modern communications, deciphering cryptographic codes that would take regular computers forever to crack. But drawing on the properties of quantum behaviour could also provide a route to truly secure cryptography.
Providing access to energy – vital for a decent standard of living and ending poverty – can be done in a way that is sustainable for people surviving on low incomes and for the planet, researchers have found.
The so-called second quantum revolution is in full swing, with scientists not only able to understand what happens at a sub-atomic level but also control this quantum behaviour enough to develop new technologies. Six months after the launch of the EU’s €1 billion quantum flagship initiative to kickstart a European quantum technologies industry, we take a look at the potential of quantum to revolutionise our future. We speak to one researcher who is helping to build a quantum computer about the global race to do this and how Europe is faring. We take a look at the threat and promise of quantum technologies in the field of cryptography and find out how quantum simulators can be used to solve non-quantum problems. And finally, we speak to the scientists who are using quantum mechanics to improve the performance of brain scanners and better diagnose medical conditions.
Scientists want to explain what exactly causes these strange radio wave flashes.
Refugees are being trained to help others in their community cope with their ordeals.
R&I missions will mean rethinking the economy - Prof. Mazzucato.
