There's been a buzz of activity at the Centers for Disease Control and Prevention in Atlanta since scientists got their first samples of a new bird flu virus from China four weeks ago.

Already they've prepared "seed strains" of the virus, called H7N9, and distributed them to vaccine manufacturers so the companies can grow them up and make them into experimental flu vaccine.

They've also come up

Forty-seven-year-old Celeste Corcoran is propped up in her hospital bed. In a nearby window is a forest of blooming white orchids from well-wishers. On the opposite wall, a big banner proclaims "Corcoran Strong."

She's recalling how thrilled she was to be near the finish line of the Boston Marathon, waiting for her sister Carmen Accabo to run by. "I just remember standing there, wanting to be as close as I could to catch her," Corcoran says. "I really just needed to see her face."

And then the first of the two bombs went off, throwing Celeste Corcoran off her feet.

The work is only in mice so far, but it sure is intriguing.

A newly found hormone revs up production of cells that make insulin — the very kind that people with advanced diabetes lack.

Harvard scientists, reporting the discovery Thursday in Cell, call the hormone betatrophin because it stimulates the production of beta cells in the pancreas. These cells make insulin, which the body needs to control blood sugar.

The largest current study of an AIDS vaccine, involving 2,500 people, is being stopped.

After an oversight committee took a preliminary peek at the results this past Monday, they concluded there was no way the study would show that the vaccine prevents HIV infection.

Nor would the vaccine suppress the wily virus among people who get infected despite being vaccinated.

So they pulled the plug on HVTN-505, as the study is called.

With Bird Flu, "Right Now, Anything Is Possible"

An international dream team of flu experts assembled in China today.

Underscoring the urgency that public health agencies feel about the emergence of a new kind of bird flu, the team is headed by Dr. Keiji Fukuda, the World Health Organization's top influenza scientist.

Before he left Geneva, Fukuda explained the wide-open nature of the investigation in an interview with NPR.

"The biggest question is just what's going to happen," he told Shots. "We've had a lot of experience in the last decade with new animal influenza viruses. But ...

Boston Doctors Compare Marathon Bomb Injuries To War Wounds

Boston hospitals always staff up their emergency rooms on Marathon Day to care for runners with cramps, dehydration and the occasional heart attack.

But Monday, those hospitals suddenly found themselves with more than 100 traumatized patients — many of them with the kinds of injuries seen more often on a battlefield than a marathon.

Like most big-city hospitals these days, Tufts Medical Center runs regular disaster drills, featuring simulated patients smeared with fake blood.

So when word came Monday afternoon that there had been died last Tuesday of respiratory and kidney failure.

The package was addressed to the CDC's top flu virologist, Nancy Cox.

Feds Fault Preemie Researchers For Ethical Lapses

Federal officials say a large study of premature infants was ethically flawed because doctors didn't inform the babies' parents about increased risks of blindness, brain damage and death.

The study involved more than 1,300 severely premature infants at nearly two dozen medical institutions between 2004 and 2009.
