Traffic engineers are learning that they can increase road efficiency and safety by eliminating left turns at many busy intersections, even those that have left turn arrows. This increases distance traveled for some people--some may have to make three right turns instead--but virtually everyone benefits in travel time, as package carrier UPS has learned. A traffic engineer and UPS official discuss how it could work.

A new study finds that organic meats are much less likely to be contaminated with foodborne pathogens. Then, fracking has been linked to higher heart attack rates in nearby communities. Then, more people are working the graveyard shift… and that means more people suffering from what’s called “shift work sleep disorder.” Then, here’s another way to cut your cancer risk—eat more mushrooms. And finally, can cannabis relieve chronic itch?

The disconnect, according to a new study, comes from society’s pervasive distrust in all governmental institutions. The lead researcher discusses how restoring faith in water could begin to restore faith in all American institutions.
Homelessness continues to be a stubborn problem despite many well-intentioned programs. A new experimental study finds that giving homeless people thousands of dollars in cash helps get many of them off the streets for good, calling into question many assumptions about the homeless and how they got that way. Experts discuss the new program and its implications for ending homelessness.
Rich countries are buying all the available COVID-19 vaccine for themselves… leaving poor countries in the cold. Then, Have you been double masking? If you haven’t been able to get the vaccine, it could be one of the best things you can do to stay safe from COVID. And finally, you may think that loud music is distracting while you’re driving… but a new study finds that young drivers are more distracted by not having music.
Proof of having received COVID-19 vaccine may soon be required for boarding a plane, going to a ball game, going to school, having a job or eating in some restaurants. An expert involved in the design of a passport app discusses how it would all work.
The number of cars on the road has been dramatically lower during the pandemic, yet the number of crash deaths has actually increased. That means the number of crashes and traffic deaths per mile driven have skyrocketed. Experts discuss this unprecedented scenario and what we can do about it.
Cars will soon be able to provide data as well as receive it. Experts explain how cars can talk with roads, traffic signals and central computers, and how roads themselves may collect data on the cars they carry. In the future, autonomous cars may use these links to greatly speed travel and make it much safer.
Researchers have been looking for an already existing drug to quickly take on COVID-19, and apparently, now they’ve found one. Meanwhile, the Food and Drug Administration has closed the door on using the malaria treatment Hydroxychloroquine (hy-drox-ee-klor-oh-quin) to treat COVID-19. Then, social isolation has been a lifesaver the last few months, but if it goes on too long, isolation can lead to shorter lifespans. And finally, when employees start going back to the …
