Study links diesel emissions to increased risk of heart failure
Researchers say the findings should prompt better regulatory policies
Although newer diesel vehicles have been found to be cleaner than regular gas-powered vehicles, there are many studies which demonstrate how harmful their emissions are to consumers. Now, a new study is adding to that evidence.
Researchers from the University of Washington have found that airborne particles from diesel exhaust can modify the DNA of babies in utero and alter the expression of their genes. The result is that these children are born with an increased susceptibility to heart failure.
"Our study adds to the large body of evidence that air pollution exposure has significant harmful effects on the cardiovascular system, and extends these findings to show the effects of this exposure on the developing heart -- effects that can last for decades," said Dr. Michael T. Chin. read more »
Mazda petrol engine breakthrough poses further threat to diesel
Japanese carmaker says from 2019 it will sell cars fitted with engines that largely eliminate need for spark plugs and boost fuel efficiency by 30%
One of the world’s largest automotive firms has hailed a technological breakthrough for the petrol engine, in an engineering twist for an industry racing to embrace the electric car.
Japanese car manufacturer Mazda claims to have designed a vehicle that will largely eliminate the need for spark plugs in petrol engines, increasing fuel efficiency by as much as 30%. The development also increases the existential threat facing diesel engines because its fuel economy could match diesel’s performance without high emissions of nitrogen oxides or sooty particulates.
Mazda said it would sell cars from 2019 with a newly developed petrol compression ignition engine, a technology that automotive manufacturers, including deep-pocketed rivals such as Daimler AG and General Motors, have been chasing for decades. The engine ignites petrol through compression, removing the need for spark plugs and increasing fuel efficiency. read more »
Uber Knowingly Leased Unsafe Honda Vezels To Drivers: Report
Former Uber CEO Travis Kalanick is reportedly engineering a bid to reassume power at the ride-hailing giant, but a new report could derail his effort before it really gets off the ground: Uber knowingly leased defective Honda Vezels to prospective drivers without getting the necessary repairs, according to the Wall Street Journal. read more »
