An outbreak of a rare and deadly form of meningitis has now sickened 26 people in five states who received steroid injections mostly for back pain, health officials said Wednesday. Four people have died, and more cases are expected.

Eighteen cases of fungal meningitis are in Tennessee where a Nashville clinic received the largest shipment of the steroid suspected in the outbreak. The drug was made by a specialty pharmacy in Massachusetts that issued a recall last week. Investigators, though, say they are still trying to confirm the source of the infections.

Too often, newborns die of genetic diseases before doctors even know what's to blame. Now scientists have found a way to decode those babies' DNA in just days instead of weeks, moving gene-mapping closer to routine medical care.

The idea: Combine faster gene-analyzing machinery with new computer software that, at the push of a few buttons, uses a baby's symptoms to zero in on the most suspicious mutations. The hope would be to start treatment earlier, or avoid futile care for lethal illnesses.

Facebook has long declared that it's "free and always will be." And it still is — unless you want more friends to see what you have to say.

The social media giant is rolling out a feature in the U.S. that lets users pay to promote their posts to friends, just as advertisers do. Facebook has been testing the service in New Zealand, where it tries out a lot of new features, and has gradually introduced it in more than 20 other countries. Facebook said Wednesday that promoting a post — such as announcing a garage sale, charity drive or big news like an engagement — will bump it higher in your friends' news feeds.

Oil prices fell for a second day Wednesday over concerns about economic turbulence in Europe, China and the U.S.

Benchmark oil was down 23 cents to $91.66 per barrel at midday Bangkok time in electronic trading on the New York Mercantile Exchange. The contract dropped 59 cents to end at $91.89 per barrel in New York on Tuesday.

A Japanese Finance Ministry official says Tokyo is hoping the recent flare-up in friction with China will not damage the two Asian economic powers' cooperation in international finance.

Takehiko Nakao, a vice minister for finance, said reports Wednesday that representatives of some big Chinese banks were canceling plans to attend the annual meetings of the International Monetary Fund and World Bank in Tokyo next week was "very disappointing."

The British government has scrapped a controversial decision to strip Richard Branson's Virgin Group of a major rail franchise, citing significant flaws in the way the decision was made.

The government announced in August that it was awarding a 13-year franchise to run the west coast London-to-Scotland service to Virgin's rival FirstGroup.

U.S. births fell for the fourth year in a row, the government reported Wednesday, with experts calling it more proof that the weak economy has continued to dampen enthusiasm for having children.

But there may be a silver lining: The decline in 2011 was just 1 percent — not as sharp a fall-off as the 2 to 3 percent drop seen in other recent years.

Police investigating two gangs called the Very Crispy Gangsters and the Rockstarz didn't need to spend all their time pounding the pavement for leads. Instead, they fired up their computers and followed the trash talk on Facebook.

"Rockstarz up 3-0," one suspect boasted — a reference to the body count from a bloody turf war between the Brooklyn gangs that ultimately resulted in 49 arrests last month.

A dog who survived an 11-mile (17-kilometer) ride from Massachusetts to Rhode Island after being hit by a car and wedged into the grille has been reunited with its owners.

The owners, who weren't identified, told WPRI-TV it's a "miracle."

A new study may reassure some women considering short-term use of hormones to relieve hot flashes and other menopause symptoms. Starting low-dose treatment early in menopause made women feel better and did not seem to raise heart risks during the four-year study.

However, the research didn't address the risk of breast cancer, perhaps the biggest fear women have about hormones since a landmark study a decade ago. The new one was too small and too short for that.
