MED-state-world-mothers-report

There is a little good news for mothers in the United States. The U.S. has only moved up six places -- from 31st to 25th -- in the annual Save The Children State of the World's Mothers report. That puts the U.S. right between Belarus and the Czech Republic. Norway is No. 1, just ahead of Iceland and Sweden.

MED-Human-Factor-Paralyzed-Teen

In the Human Factor, we profile survivors who have overcome the odds. Confronting a life obstacle -- injury, illness or other hardship -- they tapped their inner strength and found resilience they didn't know they possessed. This week Krystal Greco, 16, shares her story about pursuing her passion despite a life-changing injury -- from horseback-riding to a wheelchair and back.

TECH-abraham-lincoln-facebook

To quote "The Social Network," if Abraham Lincoln had invented Facebook, he would have invented Facebook. But in a tall tale that would have made the Great Emancipator proud, a blog post saying that he did just that was making the rounds Wednesday. And some online media outlets were quick to take the bait.

TECH-social-media-parents-netiquette

Maternity-leave laws aside, now is a pretty awesome time to be a new parent. Anyone with the Internet can get advice, connect with other parents and share photos and updates with interested parties in real time. (Think about it: Twenty years ago, it'd be much easier to feel isolated when you were at home all day with a little blinking infant who couldn't do much other than sleep, poop and cry.)

TECH-zuckerberg-hoodie-wall-street

Facebook has raked in billions and will make a splash when its stock hits the open market next week. So, what are folks on Wall Street concerned about? Mark Zuckerberg's hoodie, apparently.

TECH-Bioshock-Infinite

What was arguably the most anticipated video game of 2012 just became one of the most anticipated games for 2013. Irrational Games and Take Two announced Wednesday that "BioShock Infinite" will be delayed four months to allow developers more time to make tweaks to the game. The third installment in a popular horror series, set in a dystopian undersea universe, will now be released on February 23, 2013, instead of this coming October as previously scheduled.

Rothko-Christies-Art-Record

COMMENTARY-navarrette-police-brutality

As evidenced by media stories and public awareness campaigns, Americans have resolved to get tough on bullying. In that spirit, it's time to send a message to bullies with badges.We need to tell police who prey on the vulnerable: "No more! When you pile on a suspect and beat him to death, we will treat you just like any other alleged criminal. We will arrest you and prosecute you. And if convicted, you will go to prison for a very long time. We will make an example out of you so that other police officers will think twice before abusing their power." The messenger could be the jury that will hear the case against two police officers in Fullerton, California, a city about 25 miles southeast of Los Angeles. A judge ruled Wednesday that the officers will stand trial in the beating death last July of Kelly Thomas, a 37-year-old homeless man afflicted with schizophrenia.
