Federal healthy officials said Friday there are some early signs this year's flu season may be easing in some parts of the country. But they stressed it's far too early to tell whether the flu season has peaked.

The number of states reporting widespread flu activity is up to 47, according to the Centers for Disease Control and Prevention. But flu activity nationally fell slightly in the CDC's most recent data. Five states reported less flu than a week earlier, according to the CDC.

The Food and Drug Administration announced Thursday that it was requiring companies that make Ambien and similar sleeping pills to sharply cut the doses of the drugs.

This year's flu season started about a month early, prompting federal health officials to warn it could be one of the worst in years. They're urging everyone to get their flu shots.

But like every flu season, there are lots of reports of people complaining that they got their shot but still got the flu. What's up with that?

Well, as Michael Jhung of the Centers for Disease Control and Prevention explains, there are lots of possible reasons.

Katie Alonzo was stunned when doctors told her they couldn't get a drug her 10-year-old daughter, Abby, was taking to fight lymphoma.

"When a doctor says, 'This is what you need to take.' And then all of a sudden somebody tells you, 'Well, that is what you need to take but this isn't available so we're going to try this instead,' it's very scary," say Alonzo, who lives in Port St. Lucie, Fla.

When Sarah Gardner was 34, she started getting really worried about whether she'd ever have kids.

"I bought this kit online that said that they could tell you your ovarian reserve," Gardner, now 40, says. These kits claim they can tell women how long their ovaries will continue producing eggs and how much time they have left to get pregnant.

"Well, mine said, 'we advise really you have a baby now.' Well, sadly that letter arrived three weeks after I just split up with my long-term partner. So, yeah, it opened a massive can of worms really," she says.

This year's unusually early flu season is continuing to intensify, federal health officials say.

The number of states now reporting widespread flu activity doubled to eight in the past week, according to the latest update from the Centers for Disease Control and Prevention's.

Last week Alaska, Mississippi, New York and South Carolina were reporting widespread flu. Now, Alabama, North Carolina, Ohio and Rhode Island have joined the list.

We all know that nobody's perfect. But now scientists have documented that fact on a genetic level.

Researchers discovered that normal, healthy people are walking around with a surprisingly large number of mutations in their genes.

It's been well known that everyone has flaws in their DNA, though, for the most part, the defects are harmless. It's been less clear, however, just how many mistakes are lurking in someone's genes.

When Christine Rowan gave birth prematurely in August, her new baby was having problems breathing. So Rowan brought her daughter, Zoe, to the Children's National Medical Center in Washington, D.C., for genetic testing.

"It's funny because when we first had the testing done, we didn't even really think about the fact the testing was going to lay out all of her DNA," says Rowan, 32, who lives in Northern Virginia.

But while Rowan and her husband were waiting for the results, questions started popping into their heads.

Members of a House subcommittee clashed repeatedly Wednesday with U.S. Food and Drug Commissioner Margaret Hamburg over the outbreak of meningitis caused by contaminated steroid injections.

Public health officials are warning that people in areas devastated by Superstorm Sandy face many risks in the aftermath and are urging people to protect themselves from health threats in the water, air and even their refrigerators.

As millions of people try to put their lives back together, the most obvious threat is the floodwaters themselves. In many places, the water could be a toxic stew.

Bill Sneddon had a feeling he was in trouble when his doctor called with his latest test results.

"I just had a premonition that something's not right," said Sneddon, 68, of Ocean Township, N.J.

And, sure enough, Sneddon's instincts were right. He had prostate cancer.

"Well, it's an eye-opener, you know. I didn't know if I had to buy a yard sale sign, you know," he said. "It's a shocking thing ... It always happens to someone else."

Geneticist reported Wednesday that they had crossed a threshold long considered off-limits: They have made changes in human DNA that can be passed down from one generation to the next.

The researchers at Oregon Health & Science University in Portland say they took the step to try to prevent women from giving birth to babies with genetic diseases. But the research is raising a host of ethical, social and moral questions.

Doctors who specialize in treating infertility are making a big change in their position on a controversial practice. The American Society for Reproductive Medicine (ASRM) has concluded that freezing women's eggs to treat infertility should no longer be considered "experimental."

The group plans to officially announce the change on Monday.

Scientists in Japan report they have created eggs from stem cells in a mammal for the first time. And the researchers went on to breed healthy offspring from the eggs they created.

While the experiments involved mice, the work is being met with excitement — and questions — about doing the same thing for humans someday.

Beau Gunderson's fascinated by what he might learn from his DNA.

"I'm curious about what makes me tick, essentially," says Gunderson, 29, who writes code for a Silicon Valley startup.

So Gunderson has signed up for every genetic test he's been able to afford. And he can't wait for the price of getting his entire genetic code — his genome — to drop to about $1,000, as many are predicting is imminent.

"Yeah, if the price does drop — to a thousand bucks for example — I might pay that. That's a good personal price point for me," Gunderson said.

Sara Terry's first clue that something was wrong with her son, Christian, came just three weeks after he was born.

"We went to check on him, just like any parents go and check on their kids just to make sure they're breathing," says Terry, 34, of Spring, Texas. "And we found him in his crib, and he wasn't breathing. He was blue."

She and her husband were horrified. They rushed Christian to the hospital and learned he had several medical problems.

There's some big news out today about one of the most sensitive issues in medicine: Who's next in line for a transplant?

The United Network for Organ Sharing, or UNOS, a nonprofit in charge of distributing organs, wants to revamp the system for distributing the most sought-after organ — kidneys — for the first time in 25 years.

Kay Allen had just started work, and everything seemed quiet at the Cornerstone Care community health clinic in Burgettstown, Pa. But things didn't stay quiet for long.

"All the girls, they were yelling at me in the back, 'You gotta come out here quick. You gotta come out here quick,' " said Allen, 59, a nurse from Weirton, W.Va.

Allen rushed out front and knew right away what all the yelling was about. The whole place reeked — like someone had spilled a giant bottle of nail polish remover.

Backed by the federal government, doctors in Michigan are trying to expand the use of a controversial form of organ donation that raises disturbing ethical concerns, including questions about whether the donors are really dead. Defining dead turns out to be pretty complicated. There are two ways to declare someone dead.

For decades, scientists have thought that one of the big differences between men and women is that men can make children all their lives because men never stop making sperm. But scientific dogma said women aren't so lucky when it comes to their eggs.
