Cities have a critical role to play in fighting climate change but hard conversations lie ahead about the best way to achieve the transition to sustainability, according to Harriet Bulkeley, professor of geography at Durham University, UK. What makes cities so pivotal in fighting climate change? ‘It has taken the world quite a long time … 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

‘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

In a picture: Hunting down guerrilla tumour cells – Prof. Rolf Bjerkvig

Brain tumours contain many different types of cells, here stained different colours, which makes them complex to treat.

Professor Rolf Bjerkvig, a specialist in brain cancer research, tells us why guerrilla cells make the disease so hard to treat. Brain tumours are hard to treat completely with surgery because they leave behind cells that invade the brain. In this video, which covers 72 hours, you can see cells breaking off from a tumour to invade other … Read more

In 2003, an influential study showed that children from rich families were exposed to around 30 million more words before the age of … Read more

‘Internet of electricity’ and zero-carbon molecules will help decarbonise Europe – report

The EU should cut greenhouse gases by 80% compared to 1990 levels by 2050, according to the European Commission's low-carbon economy roadmap.

An ‘internet of electricity’, zero-carbon cities and turning European soils into carbon sinks are among a slew of ambitious ideas to decarbonise our society and slash greenhouse gas emissions proposed by environmental experts in a reportpublished on 28 November. ‘The message in our report is that this decarbonisation business is potentially a huge economic opportunity,’ said Professor … Read more
