Small changes to aircraft flight paths to avoid the atmospheric conditions that create condensation trails - known as contrails - could reduce aviation's global warming impact by nearly half, a new study suggests. The study, led by researchers at the University of Cambridge, suggests that changing cruising altitude by a few thousand feet, either up or down, could prevent contrails from forming.

Insulated joint systems are crucial for safe railway operation, but are susceptible to faults. The newly developed insulated joint is intended to extend service life and reduce maintenance and repair costs. Insulated joints are little known, but many railway lines could not be used without them. They divide the rail network into electrically separated sections and register when a train enters and leaves a section.

A new Simon Fraser University study has found that Canada's cycling network is growing, but not everyone is benefitting. Between 2022 and 2024, nearly 3,600 kilometres of high-quality cycling infrastructure was added across the country, with the largest proportional increases seen in smallto medium-sized cities.

A new study led by researchers at ETH Zurich and the Paul Scherrer Institute PSI in collaboration with African partners shows that electric vehicles could be economically competitive in many African countries before 2040 - just as long as charging infrastructure is developed and geared specifically towards solar powered off-grid systems.

Researchers at the Institute for Meteorology at Leipzig University have, for the first time, determined the climatic impact of contrails that form within natural cirrus clouds. Contrails account for the largest share of aviation's climate impact beyond carbon dioxide emissions. The Leipzig researchers have now shown that "hidden" contrails - previously not factored into such assessments - contribute up to ten per cent of the warming effect of normal, freely visible contrails.

Electric vehicles (EVs) are no more dangerous to pedestrians than traditional petrol or diesel cars, according to a new study. Research by the University of Leeds into UK collisions involving pedestrians and cars found no significant difference in the pedestrian casualty rates between EVs and conventional vehicles.

Researchers at Universidad Carlos III de Madrid (UC3M) have developed a set of innovative methods and algorithms that improve the performance and precision of vehicle design through topological optimization, a mathematical technique that allows designs to be optimized by distributing materials efficiently.

The measures introduced in Switzerland to improve protection for cyclists at intersections have their limits in practice, as a study by the University of Lausanne has shown. Many cyclists fear riding in the center of the lane at roundabouts, or hesitate to turn right at red lights when authorized. This may be due to a feeling of lack of legitimacy, fear of being stigmatized or fears for their safety.

Lake George's fault zone is similar to several major active systems worldwide including the San Andreas Fault in California, new ANU research shows. George Booth Senior Media and Communications Officer Scientists from The Australian National University (ANU) have analysed signals generated by the vibrations of traffic along the Federal Highway to learn more about the seismic nature of Lake George, situated north-east of Canberra.

According to a study by UNIGE and Empa, real-time data on the energy mix and electricity prices should be accessible to enable more environmentally friendly charging of electric vehicles.

New measure shows micromobility takes up just 2% of road space, despite a measurable need for more in certain boroughs Bike lanes, BIXI stations and other micromobility infrastructure make up just two per cent of Montreal's street space - even in neighbourhoods where cycling demand would justify more - according to a new study by McGill researchers.

Female pilots perform better under pressure, study finds. Female pilots may outperform their male counterparts in high-pressure flight situations, according to a new study led by University of Waterloo researchers.

Empa and the Touring Club Switzerland (TCS) have, for the first time, conducted a joint research project. The study set out to investigate how the noise levels of electric cars and cars with combustion engines differ. While hardly any differences can be detected at constant speed, e-cars are significantly quieter when accelerating.

Flight ticket prices could rise by 50 percent if aviation is made climate-neutral. This is an estimate from a new study by researchers at ETH Zurich. It is based in particular on the use of synthetic fuels. Sustainably produced synthetic fuels burn more cleanly and thus generate less condensation and other climate-warming effects.

Hydrogen-powered planes are set to take wing around the world in the future. To make this possible, engineers have to develop the jet engines that will power them. Experiments by researchers at ETH Zurich are now providing the necessary basis for making these engines powerful and durable. Europe is preparing for climate-neutral flight powered by sustainably produced hydrogen.

Engineers at EPFL and ETH Zurich have come up with a new approach for reducing traffic congestion in large cities during rush hour. Their system is designed to be both fair and effective. Rush-hour traffic congestion is a major headache for commuters and a real problem for city planners. Worldwide, a huge amount of time is wasted stuck in traffic.

EPFL professor's passion for sustainable flying and expertise in machine learning and computer vision drives innovation in green aviation design and beyond. Aerodynamic shape optimization (ASO) is a key technique in aerodynamic design aimed at enhancing an object's physical performance while adhering to specific constraints.

Racial discrimination against Black passengers looking to hail rides has been a problem since the taxi-cab era. A new study from researchers in Carnegie Mellon University's College of Engineering aimed to find out whether the rise of ride-hailing apps like Uber and Lyft has changed that dynamic - for better or worse.

Laval University team sheds light on the effects of financial assistance on the acquisition of zero-emission vehicles Incentive policies for the purchase of green, electric or hybrid vehicles are associated with an increase in their adoption, according to a study by the Faculty of Business Administration.

Data suggests the switch to EVs may not mean the loss of assembly jobs some predicted Study: Higher labor intensity in US automotive assembly plants after transitioning to electric vehicles (DOI: 10.1038/s41467'024 -52435-x) U.S. auto plants producing battery electric vehicles have required a larger workforce than traditional internal combustion engine plants-a finding that runs counter to early predictions about how EVs would impact the industry.
