Airlines are keen to start using autonomous commercial aircraft to reduce flight crew costs and address pilot shortages, writes former Engineers Ireland president Dr Chris Horn.

If Europe is to meet its ambitious environmental goal of becoming carbon neutral by 2050, more and more people will need to cycle to get around. As World Bicycle Day, which took place in early June, celebrated pedal power’s undeniable benefits, we are curious to know what the bike and ebike of the future might look like.

Researchers use artificial intelligence to help autonomous vehicles avoid idling at red lights.

Cities need to reimagine themselves by remaking what is possible to match what is necessary. At the heart of this, guided by better evidence of what works, they must do more to break free from cars, writes Kimberly Nicholas, associate professor of sustainability science, Lund University.

In the UK, 15% of women report experiencing harassment on buses or trains – leading to higher use of private vehicles, which many women view as safe 'cocoons' for mobility. Sharing transport through a system known as 'Mobility as a Service' could help; if the sexes adopted it at the same rate, there would be a significant positive impact on the environment, with thousands of private cars no longer needed on roads, writes Maurizio Catulli.

Dimitris Michailidis and David Hogan discuss their proposal to develop a binder and bituminous mixture which allows Reclaimed Asphalt Pavement (RAP) mixtures to be produced at lower temperatures in the cold addition process. Alongside the environmental benefits of such an approach, it is also hoped that reduced ageing of the material through the mixing process will result in improved performance.
