A long-term study of the health of Canadian children has found that exposure to ozone (O 3 ) at birth was associated with an 82% increased risk of developing asthma by age three. The study, which was a 10-year follow-up to the 2006 Toronto Child Health Evaluation Questionnaire (T-CHEQ), was presented at the 2018 American Thoracic Society International Conference in San Diego. For this part of the T-CHEQ study, 1,881 children were followed from birth to 17 years of age, on average. MORE

A new study indicates. emissions hydrogen Study plug-in cars hydrogen fuel cellThere's been considerable debate among advocates of battery-electric and hydrogen fuel-cell cars over which technology is better for the environment. While neither vehicle type produces any tailpipe emissions, their overall emissions vary depending on the fuels and processes used to generate electricity or produce hydrogen. MORE

Study MIT plug-in cars range anxietyRange anxiety, the persistent worry about not having enough battery range to finish a journey, remains one of the major obstacles to widespread electric-car adoption. Many electric cars still have shorter ranges than comparable internal-combustion models, and that continues to spook some consumers. But could those concerns be overblown? DON'T. MORE
