Update at 1:30 p.m. ET. State of emergency in Missouri.

Missouri Gov. Jay Nixon has declared a state of emergency due to the heavy snowfall. The declaration allows state agencies to work directly with county and city emergency responders.

Jennifer Davidson of member station KSMU reports that about 40 people are staying at The Salvation Army in Springfield, which provides beds, blankets, and food for families in need.

As many as 30 million people living from Oklahoma to the Ohio Valley are in the path of a storm moving east out of California that could dump several inches of snow in some areas and freezing rain and sleet elsewhere in the next few days.

According to the Weather Channel, the storm is caused by an "upper-level dip in the jet stream," on Wednesday.

New Zealand seems to be the destination of choice for wayward Antarctic penguins.

If the Chinese military is regularly hacking into the computers of U.S. organizations, as an American security firm says, it raises all sorts of questions about how the U.S. should respond.

Is this a job for the military or the intelligence agencies? What role should diplomats and trade officials be playing?

The report issued this week by the IT security consultancy Mandiant says it has traced the hacking activity to the People's Liberation Army's Unit 61398, which has "systematically stolen hundreds of terabytes of data from at least 141 organizations."

Two reports on troubles with lithium ion batteries aboard Boeing's 787 Dreamliner:

In Japan, where a battery on an All Nippon Airlines 787 overheated and began smoking on Jan. 16, forcing the plane to make an emergency landing, the Transport Ministry released a report Wednesday saying it found that the battery in question had been improperly wired.

Investigators trying to piece together a motive in December's killings in Newtown, Conn., believe that 20-year-old shooter Adam Lanza may have been inspired by a similar 2011 massacre in Norway.

The Hartford Courant and CBS News report that authorities searching through Lanza's belongings after the shooting at Sandy Hook Elementary discovered several news articles about Anders Behring Breivik, who killed 77 people in Norway in July 2011.

Russians might be forgiven for thinking they have a big, fat celestial bull's-eye painted on their heads.

When the boyish Kim Jong Un assumed power in North Korea barely a year ago after his father's passing, speculation was that he might strike out a more open and less provocative path.

Figuring out what is or isn't going on in North Korea has long been an exercise in reading tea leaves, and no one predicting a thaw in the hard-line hereditary regime did so without qualification.

Ahead of North Korea's latest nuclear test, the country launched a preemptive barrage of propaganda aimed at the West. But in the age of the Internet, has such ham-fisted messaging lost its punch?

The latest North Korean video, released on YouTube last week in apparent anticipation of Tuesday's test, is something of an amateurish production.
