What do you do to unwind after a long, hard day at work? Some of us like to veg out on the couch, drink a glass of wine, or — in the case of some of the world's top business leaders — practice meditation. Specifically, transcendental meditation.

Transcendental meditation is a technique that involves closing your eyes, 20 minutes twice a day, so that you can "experience a field of calm deep within."

Why facial recognition software has trouble recognizing people of color

Feb 13, 2018

Facial recognition software has made huge advancements in accuracy, but it has a long way to go — specifically when it comes to recognizing people of color. Commercially available software can tell the gender of a person using a photograph. But according to researcher Joy Buolamwini, of the MIT Media Lab, that software is correct 99 percent of the time when it’s looking at a white male and less than half as accurate when looking at a darker-skinned female. Marketplace Tech host Molly Wood spoke with Buolamwini about her research and the human biases that creep into machine learning.

The opioid epidemic has cost the U.S. more than a trillion dollars since 2001, according to a new study, and may exceed another $500 billion over the next three years.

It's a year later than first promised, but President Trump finally announced his long-awaited infrastructure plan at the White House today, flanked by governors, mayors, and other state and local leaders. Calling the condition of the country's roads, bridges, ports, tunnels and water systems "horrendous," Trump says his plan "will spur the biggest and boldest infrastructure investment in American history. The framework will generate an unprecedented $1.5- to $1.7-trillion investment in American infrastructure."

The darkest building on the planet is at the Olympics

Feb 12, 2018

Among the skating rinks, the bobsled tracks and the ski slopes of the Winter Olympics in Pyeongchang stands something completely different — what's being called the darkest building on the planet. It's a pavilion sponsored by Hyundai painted with a high-tech new color that its maker says is the world's darkest man-made substance.  

On infrastructure, Donald Trump has a math problem

Feb 12, 2018

Today, the White House outlined a $1.5 trillion plan to deal with our nation’s infrastructure problems — everything from waterways to highways to commercial space infrastructure. But the federal government plans to provide just $200 billion of that $1.5 trillion. Where would the rest come from? Mostly from state and local governments, who already feel burdened by federal policy.

President Trump released his long-awaited plan to direct $1.5 trillion toward upgrading U.S. roads, bridges, airports and other public works projects. NPR's Mary Louise Kelly speaks with DJ Gribbin, special assistant to the President for infrastructure policy, about Trump's priorities.

With her MBA in hand, Jessica Saturley-Hall knew she wanted to start her own business, and she got hooked on the concept of compost. She knew that food scraps produce significantly more methane, a greenhouse gas, when tossed in a landfill, rather than breaking down on their own. So she wondered, what if you could somehow reward people for separating their food waste from their trash?

At first, she thought about the idea of somehow paying people for their compost. She ran a host of financial models, looked at it every which way, but couldn’t come up with a solution.

The fiscal year 2019 budget the White House released today isn't what you might call an "operative" piece of fiscal policy. Congress hammered out a two-year spending plan just last week, after all. But the budget is still worth a read for some of the assumptions the Trump administration's making — like a decade of economic growth at 3 percent or more. We'll start the show by unpacking that and the White House's new infrastructure plan, and the math issues therein.

But maybe it isn’t.
