Oregon Fines Man For Writing a Complaint Email Stating 'I Am An Engineer' - Slashdot
Since the engineering board in Oregon said Jarlstrom should not be free to publish or present his ideas about the fast-turning yellow traffic lights, due to his "practice of engineering in Oregon without registration," he and the Institute for Justice sued them in federal court for violating his First Amendment rights. "I'm not practicing engineering, I'm just using basic mathematics and physics, Newtonian laws of motion, to make calculations and talk about what I found," he said. Sam Gedge, an attorney for the Institute for Justice, told Motherboard: "Mats has a clear First Amendment right to talk about anything from taxes to traffic lights. It's an instance of a licensing board trying to suppress speech."

More than 95% of world's population breathing unhealthy air, says new report | Hacker News
among 6.6 million people in the province of Ontario, those living within 50 meters of a major road—where levels of fine pollutants are often 10 times higher than just 150 meters away—were 12% more likely to develop dementia than people living more than 200 meters away.

>> Just how the fine airborne particles might travel from a rodent’s nasal cavity to its brain is a mystery. But a research team led by Günter Oberdörster at the University of Rochester in New York has used traceable, radioactive specks of elemental carbon to demonstrate that inhaled particles smaller than 200 nanometers can get through the delicate tissues lining a rodent’s nasal cavities, travel along neurons, and spread as far as the cerebellum, at the back of the brain, triggering an inflammatory reaction.

>>"In 1403 elderly women, the total volume of white matter—the insulated nerve fibers that connect different brain regions—decreased by about 6 cubic centimeters for every 3.5-µg/m3 increase in estimated PM2.5 exposure, based on air monitoring data from participants’ residences for 6 to 7 years before the brain scans were taken. Chen’s white matter findings are consistent with studies of cultured neurons, which show that exposure to PM2.5 can cause myelin—the fatty insulation that wraps around neuronal axons—to “peel up at the ends, like a Band-Aid,” Block says"

Could roundabouts prevent a future Humboldt Broncos tragedy? | National Post
The paper analyzed 17 American intersections that had collectively killed 11 people over a roughly five-year period. After being converted into roundabouts, however, researchers found that injury-causing crashes plummeted by 84 per cent and fatal crashes stopped entirely.

In 2017, Minnesota highway officials conducted a safety audit of 144 roundabouts constructed in the state since the 1990s. On average, they found that the roundabouts caused an intersection’s fatal crash rate to plunge by 86 per cent, and the rate of “serious injury” crashes to go down by 83 per cent.

Roundabouts have also been widely adopted in Europe and Australia. According to data gathered by the U.S. Transportation Research Board, Australian roundabouts have brought down injury-causing crashes by up to 87 per cent. In Germany and the Netherlands, roundabouts were found to bring down total crashes by more than one third.
