Coffee is one of the most popular drinks worldwide, with countless cups of the dark, alluring elixir brewed up each day. And, lucky for those coffee-guzzlers out there, mounting data suggest it’s good for you; moderate coffee drinking has been linked to lowered risk of cardiovascular disease, liver diseases, diabetes, and an overall lowered risk of dying too soon.

But, as coffee-lovers happily continue sipping their morning fix with a dash of self-satisfaction, it’s worth noting that not every cup of coffee is equal. Brewed coffee can vary wildly in its flavor and chemical make-up, particularly the chemicals linked to health benefits. Everything that happens before the pour—from the bean selection, roast, grind, water, and brew method—can affect the taste and quality of a cup of joe.

So far, there’s little to no data on the health impact of drinking one type of coffee over another. In studies linking coffee to lowered risks of disease and death, researchers mostly clumped all coffee types together, even decaffeinated coffee, in some cases. But, there is a fair amount of data on individual components of coffee that are flavorful and beneficial—and how to squeeze as much them as possible into your mug. Here’s what the science says:

It's been about two months since I've vacuumed my house, and the floor has never been cleaner. That's because I haven't been doing it—a robot has. For the past two months we've had a Neato BotVac Connected rolling around the house, the latest robo vac in Neato's lineup. Like all Neato robots, this has a spinning LIDAR unit that maps out the house. In this new "Connected" version, it's got Wi-Fi and a smartphone app.

The household name in household robots is definitely iRobot's Roomba, a round robotic vacuum cleaner that popularized the idea of having a little bot clean up after you. The fundamentals of the Roomba haven't changed much since its introduction: it's a vacuum on motorized wheels with a bumper plate in the front. When the plate bumps into something, the robot knows it hit an obstacle and changes directions. Start a Roomba on floor and usually it will spiral outward until it hits a wall, try to feel out the perimeter of the room, and then ping pong all across the center of the house in an attempt to cover the interior space.

Most Roombas can't "see." Its only window to the outside world is the little bumper plate—it feels its way around a space by running into stuff. Roomba will say it takes this limited information and runs it through an algorithm to be a little smarter than "randomly driving around," but to the human eye, there's little logic to where the little disk is driving.

DAYTONA BEACH, Fla.—The Rolex 24 at Daytona is the start of the American sportscar racing season. Since it happened to coincide with my 40th birthday, we decided to fly down to Florida to check it out. The main event is a 24-hour race for the WeatherTech SportsCar Championship, which you might remember last year as the Tudor United SportsCar Championship. The race involves four different classes of car racing on track at the same time.

The fastest cars race in the Prototype class, a mix of older Daytona Prototypes (tubeframe race cars) and LMP2s (carbon fiber prototypes that race at Le Mans). Next quickest are the GTLM cars, which are factory-supported racecars based on roadgoing machines like the Corvette Z06 and Porsche 911. Both Prototypes and GTLM feature lineups of professional drivers, many of whom are world-class. Several stars of NASCAR and IndyCar were in the field this year.

The next two classes are pro-am, where wealthy amateurs are joined by professional hotshoes. There are the Prototype Challenge cars, which are all identical open-cockpit cars with Chevy V8s. The other pro-am class is GTD, which this year uses the GT3 technical ruleset. Like the GTLM cars, these are based on road-going machines like Lamborghini Huracáns and Dodge Vipers, but there is less room for technical development.

It's been an action-packed race so far (with almost six hours left to run at the time of writing). Who wins is anyone's call. You can catch the end of the race on Fox Sports or streaming via the IMSA website or app.
