Quantum simulation could help flights run on time

Quantum simulators could help solve logistical challenges, such as making sure planes and airline crew are in the right place in order for flights to run smoothly. Image credit - Pixabay/ Free-Photos, licensed under pixabay license

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. While modern digital computers are capable of impressive feats of calculation, there are some … Read more

Aeroplanes could cut emissions by flying on waste cooking oil fuel

Biofuels have the potential to reduce aviation emissions by 90%, according to the European Commission’s Joint Research Centre.

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 … Read more

Small farms produce more food than statistics show

Recording the true production levels of small farms could help farmers access greater support, according to researchers.

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. While small farms can play an important role in supporting rural economies, many owners struggle to earn a decent living which can lead … Read more

Quantum – a double-edged sword for cryptography

Cryptography that would be impossible for a regular computer to crack, would take a quantum computer just seconds.

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. Defence, finance, social networking – communications everywhere rely on cryptographic security. Cryptography involves jumbling up … Read more

Why providing the necessary energy to end poverty need not cost the Earth

It is possible to increase access to basic living standards within the current national levels of energy use in India, Brazil and South Africa, research shows.

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. As people’s living standards rise, their energy use usually does too. But a growing demand for better … Read more

‘Quantum computers will soon outperform classical machines’

As a quantum computer can be in many states at the time it enables the calculation of many possibilities at once, says Dr Thomas Monz. Image credit - Flickr/IBM Research, licensed under CC BY-ND 2.0

European scientists have spent 100 years developing the field of quantum mechanics – a branch of physics dealing with the atomic and subatomic scale – and we need to reap the profits now that quantum computers and other technologies are becoming a reality, according to Dr Thomas Monz from the University of Innsbruck, Austria. He … Read more
