Dogs often get credit for being humans' constant companions. But dogs have nothing on tuberculosis bacteria.

TB and people have been trapped in a relationship that's been going on for thousands of years — perhaps even tens of thousands of years, scientists said earlier this week.

Compare Yahoo's new logo, introduced Thursday, to what was there before.

According to CEO Marissa Mayer, "we knew we wanted a logo that reflected Yahoo — whimsical, yet sophisticated. Modern and fresh, with a nod to our history. Having a human touch, personal. Proud."

On her Tumblr page, Mayer goes on at length about how:

Parents' Harsh Words Might Make Teen Behaviors Worse

Sure you're steamed. But teenagers tend to meet harsh words with even worse behavior, a study says.

Most parents yell at their kids at some point. It often feels like the last option for getting children to pay attention and shape up.

But harsh verbal discipline may backfire. Teenagers act worse if they're yelled at, a study finds.

Researchers asked parents of 13-year-olds in the Philadelphia area how often in the past year they'd yelled, cursed or called the kid "dumb or lazy or some other word like that" after he or she had done something wrong.

Stanley Kunitz, one of our great poets, planted a spruce tree next to his house in Provincetown, Mass., and over the years that tree attracted some tenants, a family of garden snakes. I didn't know garden snakes climb trees, especially needly ones like a spruce, but they do.

STEVE INSKEEP, HOST:

Companies that collect and sell information about you are usually pretty secretive about what they have on you. But one of the biggest data brokers is now letting consumers have a peek.

Yesterday, the Acxiom Corp. set up a website where people can look themselves up. It's called AboutTheData.com. As NPR's Martin Kaste reports, some of the first people to try it were the data industry's critics.

Typically, 21st century writers fall into two technical categories: Mac or PC. But poet Henry Goldkamp would much rather use a typewriter. He's the sole owner of a mobile poetry business, and for the past three years, he's spent his weekends traveling St. Louis, banging out short poems, on the spot, for anyone who stops by his table.

Scientists Demonstrate Leaner System For Quantum Encryption

Navajo encryption boxes seen at right in 2003 employ principles of quantum physics. The latest research has shown the ability to run larger networks with less such hardware.

Scientists have demonstrated the ability to scale-up an 'uncrackable' computer encryption system that utilizes quantum physics to ensure security.

The technique is based on information that is carried by photons, the basic particles of light. While it's been demonstrated on a small scale, the team headed by Andrew Shields and publishing in Nature says they've shown that up to 64 users can share a single photon detector, eliminating the need for each one to have such an (expensive) device.

Multitasking After 60: Video Game Boosts Focus, Mental Agility

Strenuous mental exercise like reading difficult books, solving tricky math problems — or, maybe, playing the right video game — can help keep a healthy brain sharp, research suggests.

A brain that trains can stay in the fast lane. That's the message of a study showing that playing a brain training video game for a month can rejuvenate the multitasking abilities of people in their 60s, 70s and 80s.

"After training, they improved their multitasking beyond the level of 20-year-olds," says Adam Gazzaley, one of the study's authors and a brain scientist at the University of California, San Francisco.

Fixing Stove Hoods To Keep Pollution Out Of The Kitchen

Cooking on gas and electric stoves can create indoor air pollution. The best way to avoid it is to buy a good range hood that vents outside, experts say.

Hot summer days often mean air pollution warnings in big cities. But the air inside your kitchen can sometimes be just as harmful. Cooking fumes from your stove are supposed to be captured by a hood over the range — but even some expensive models aren't that effective.

Jennifer Logue spends a lot of time thinking about what happens when she cooks. She's a research scientist at Lawrence Berkeley National Lab, where she studies indoor air pollution.
