America's Best and Worst Cities for Public Transit

Trains, Buses, People: An Opinionated Atlas of U.S. Transit, a new release from Island Press, is undoubtedly a book for transit nerds. But everyone else could learn a little something from it, too. In just a few quick visuals, it's able to distill why transit use is common in some big cities in the U.S., while in others, people are chained to their cars.

The density maps, which we first spotted over on CityLab, highlight where the most people live and are employed in major U.S. cities, overlaying information about how accessible frequent rail and/or bus service is in that area. The combined data show a realistic picture of how accessible certain parts of a city are, illuminating which U.S. cities, and which of their neighborhoods, are easiest to get around without a car.

Sure, there are likely bus lines that run farther out beyond the bounds of downtown, but frequency is one of the most important predictors of whether people actually use transit or not. So is distance—you're not going to get many riders if people have to drive to your bus stop—and while some planners consider a quarter-mile to be the ideal maximum distance to be considered "walkable" distance to transit, others, including those running major transit agencies like the Washington D.C. Metro, use a half-mile as the standard. (The book's author, Rice University urban planner Christof Spieler, served on the board of directors for the Houston METRO from 2010 to 2018.)

The resulting infographics portray the reality of American transit options. Even in cities we imagine are great for public transportation (New York) there are wide swaths of densely populated geography that are virtually inaccessible. Other cities known for their over-dependency on the car (Los Angeles) actually might have far more transit options than you imagine.

So what U.S. cities have the overall best transit coverage, according to Spieler? He names these cities as the five best: New York City, Boston, San Francisco, Seattle, and Washington, D.C.

And the most useless? As far as individual rail lines go, Nashville's $41 million Music City Star line carries fewer people than most bus routes. St. Clair County, Illinois, has a MetroLink line running from St. Louis eastward to serve "literal corn fields," Spieler writes. A Cleveland light-rail extension built in the 1990s serves a pathetic 400 people a day. Dallas's system, DART, is the biggest light-rail line in the country, but it "reaches remarkably few places," carrying half as many people per mile as transit in San Diego, Phoenix, or Houston.

In general, recent American transit projects cost taxpayers a ton of money and serve relatively few people—New York, despite having one of the best transit systems in the U.S., has paid $18.9 billion over the last 10 years on a mere three subway stations and one commuter-rail station.

The ChopBox Smart Cutting Board Has a Food Scale, Timer, and Knife Sharper Built Right Into It

When it comes to furnishing your kitchen with all of the appliances necessary to cook night in and night out, you’ll probably find yourself running out of counter space in a hurry. The ChopBox, which is available on Indiegogo and dubs itself “The World’s First Smart Cutting Board,” looks to fix that by cramming a bunch of kitchen necessities right into one cutting board.

In addition to giving you a knife-resistant bamboo surface to slice and dice on, the ChopBox features a built-in digital scale that weighs up to 6.6 pounds of food, a nine-hour kitchen timer, and two knife sharpeners. It also sports a groove on its surface to catch any liquid runoff that may be produced by the food and has a second pull-out cutting board that doubles as a serving tray.

There’s a 254nm UVC light featured on the board, which the company says “is guaranteed to kill 99.99% of germs and bacteria" after a minute of exposure. If you’re more of a traditionalist when it comes to cleanliness, the ChopBox is completely waterproof (but not dishwasher-safe) so you can wash and scrub to your heart’s content without worry. 

According to the company, a single one-hour charge will give you 30 days of battery life, and can be recharged through a Micro USB port.

The ChopBox reached its $10,000 crowdfunding goal just 10 minutes after launching its campaign, but you can still contribute at different tiers. Once it’s officially released, the ChopBox will retail for $200, but you can get one for $100 if you pledge now. You can purchase the ChopBox on Indiegogo here.

How Coronavirus and 31 Other Infectious Diseases and Viruses Got Their Names

As you may already know, the corona in coronavirus has no relation to a certain refreshing beer often served with a slice of lime. Corōna means “crown” in Latin—and Spanish and Italian, too—and virologists chose it in 1968 to describe the group of viruses characterized by crown-like spikes that protrude from their surfaces.

So how do other viruses and diseases get their names? Based on the infographic below, created by Adam Aleksic for his website, The Etymology Nerd, there isn’t just one way. Some, like the coronavirus, are named for how they look under a microscope. The rota in rotavirus, for example, which means “wheel” in Latin, reflects the virus’s wheel-like appearance when viewed beneath an electron microscope.

Others are named after the locations where they were discovered or studied. In 1947, scientists named a newly identified mosquito-borne virus after Uganda’s Zika Forest. In 1977, Yale researchers investigating a string of pediatric arthritis cases in the town of Lyme, Connecticut, started referring to the illness as “Lyme arthritis.” Later, the name was modified to “Lyme disease” when scientists realized patients were exhibiting other symptoms, too.

Still others are characterized by the symptoms they cause. People with tetanus—from the Greek tetanos, for “tension”—usually experience muscle stiffness, and the skin of yellow fever sufferers often takes on a yellow tint due to jaundice.
