Microsoft hasn't exactly had a great couple of years.

Its new Windows 8 operating system was held responsible for the drop in PC sales last quarter. Sales of its Windows Phones lag far behind both the iPhone and Google's Android phones.

The light in the darkness for Microsoft has been the Xbox 360, which has been the top-selling game console for over two years — beating out both the Nintendo Wii and Sony's PlayStation. On Tuesday, Microsoft is expected to announce a new version of the Xbox.

Yahoo's $1.1 billion purchase of Tumblr could be considered a bargain compared with its other big-dollar bets. The company's history is dotted with pricey purchases of once-hot Web properties that had more promise than eventual purpose. A look back:

GeoCities, 1999: $3.7 Billion

When movie stars become unbankable, they're no longer a slam dunk at the box office. When investments become unbankable, they're relegated to the Wall Street's junk pile. For ordinary Americans deemed unbankablethose who don't have a traditional checking or savings account — it can be hard to simply pay bills.

And that absence of a bank account is about to become a big problem for those who also lack health coverage — and for the health insurance companies trying to sell them coverage. After all, how do you sell a product to a customer who has no easy way to pay you?

Men who were diagnosed with ADHD as children are more likely to be obese in adulthood, according to a new study.

The men who had ADHD weighed 19 pounds more at age 41 than otherwise similar men who hadn't had ADHD as boys, the researchers found.

One way to know how much soda people drink is to ask them.

The problem? We tend to underestimate, lie or forget what we've consumed.

And this is a challenge for researchers who study the links between sugar-sweetened beverages and obesity.

NPR's business news starts with a big blogging buyout.

Today, Yahoo announced its purchase of the blogging site Tumblr. The $1.1 billion deal was unanimously approved by Yahoo's board. Analysts say the acquisition is Yahoo's attempt to revitalize itself.

NPR's Kirk Siegler has more.

Her hair is brown and tied back into a professional-looking ponytail. She wears a blue shirt, tan sweater and delicate gold chain. It's the first time she has met the man sitting across from her, and she looks out at him, her eyes curious.

"So how are you doing today?" she asks cautiously, trying to build rapport.

As the country awaits two important Supreme Court decisions involving state laws on same-sex marriage, a small but consistent body of research suggests that laws that ban gay marriage — or approve it — can affect the mental health of gay, lesbian and bisexual Americans.

By all the laws of anything, Winston Chen should not have quit his well-paying, midcareer job at a software company at age 40. But one day he was watching a TED Talk, one of those popular online video presentations, delivered by a New York designer.

"He presented this absolutely irresistible idea," Chen says. "He said, 'Why don't we take five years out of retirement and spread them throughout your working life?' "

You're out navigating the jammed sidewalks of Kenya's capital city when you suddenly realize you're in desperate need of a toilet. You crane your neck over the crowds, vainly seeking a McDonalds, a Starbucks — no such luck. What next?

There could be an app for that. Twendeloo, which is Swahili for "Let's Go to the Loo," would allow you to use your phone to locate the nearest public restroom in Nairobi's business district, then give it a rating for cleanliness.

Communications barriers have long vexed us, as showcased in the movie "Rush Hour."

(SOUNDBITE OF MOVIE, "RUSH HOUR")

CHRIS TUCKER: (As Carter) Do you understand the words that are coming out of my mouth?

LYDEN: Scientists in the 17th century were working hard to understand; mainly, the secrets of the universe but also, each other. With Latin on the decline, they were seeking a whole new way of communicating that would defy barriers and borders - a universal language.

There is no shortage of diet programs available to those that seek to lose weight. But for many, taking those initial steps into a weight loss and exercise program can be an intimidating leap.

A new study from the University of Kansas Medical Center, however, shows that the online game Second Life helped some people lose weight — and keep it off — in real life.

Alzheimer's Cases Rise, But Hope Remains

May 18, 2013

More than 5 million Americans are currently living with Alzheimer's disease, and the National Institute on Aging estimates that that number is going to triple by 2050 — in part due to aging baby boomers.

The cost of coping with the disease — currently estimated at $215 billion — is projected to rise to half a trillion dollars by 2050. That amount will likely tax our overburdened health care system, the economy and the families of those affected.

Amy Goyer realized her 84-year-old father Robert's health was deteriorating one night while watching a movie with him.
