Officials Prepare For Another Flu Pandemic — Just In Case Those people who have contracted the H7N9 virus have become very sick. And unlike the older bird flu virus, this one shows some adaptation to mammals, making it a matter of concern. But it doesn't make chickens sick, posing unique difficulties in fighting this kind of flu. |

Researchers Find Hormone That Grows Insulin-Producing Cells When researchers turned on a gene for the hormone in the livers of diabetic lab mice, the number of insulin-making cells in their pancreas glands tripled within 10 days. Although the research was conducted in animals, the scientists say the findings could be relevant for humans. |

With Bird Flu, 'Right Now, Anything Is Possible' An international team of disease detectives are in China to investigate an outbreak of a new strain of bird flu, H7N9. The biggest puzzle right now is where these infections are coming from, as testing poultry has turned up very few infected birds. |

Boston Doctors Compare Marathon Bomb Injuries To War Wounds These days hospitals drill for mass-casualty disasters like the explosions at Monday's Boston Marathon. But when it happened for real, the first response was disbelief. Then the victims began arriving. Doctors say they were confronted with the kinds of IED injuries that U.S. troops have gotten in Iraq and Afghanistan. |

Scientists Race To Stay Ahead Of New Bird Flu Virus "The top priority is diagnosis — the capability to be able to pick up this virus, should it emerge outside of China," says virologist John McCauley. Flu researchers are getting started on creating a vaccine, but there are still many unknowns. |

Feds Fault Preemie Researchers For Ethical Lapses Infants received different levels of oxygen to see which was better at preventing blindness without increasing the risk of nerve damage or death. But the federal government says doctors in the study didn't tell parents enough in advance about the "foreseeable risks" to their children. |

Novartis Ruling Reverberates Past India's Borders India's Supreme Court says drug maker Novartis can't hold onto its patent for the pricey cancer drug Gleevec simply by tweaking its chemical formula. That means generic drug makers can keep making a form of the drug at a tenth of Novartis's price. Consumer advocates call it a major advance for access to generic drugs. The drug industry says it will chill companies' willingness to produce innovative products. |

As Stroke Risk Rises Among Younger Adults, So Does Early Death A study found that 1 in 5 adults ages 20 to 55 who survive strokes will die within 20 years of the event — a rate much higher than doctors expected. The findings mean doctors need to pay a lot more attention to younger stroke survivors. |

Catalog Of Gene Markers For Some Cancers Doubles In Size The largest gene-probing study ever done has found dozens of new genetic markers that flag a person's susceptibility to breast, ovarian and prostate cancer. But knowing these susceptibility markers won't mean much for patients for now. |

Sorting Out The Mammogram Debate: Who Should Get Screened When? Researchers suggest that guidelines for regular breast cancer screening should look beyond a woman's age. Dense breast tissue, a cancer risk factor, may be a reason to consider earlier screening with mammograms. |

To Control Asthma, Start With The Home Instead Of The Child Because dust, mold and pests can trigger asthma attacks, addressing these triggers in the home can keep kids from winding up in the hospital. In the past seven years, the Community Asthma Initiative in Boston has counseled more than a thousand families on how to prevent attacks. |

More Patients Keep HIV At Bay Without Antiviral Drugs French researchers confirm that the immune systems of 14 adults are apparently controlling HIV without medication. It's further evidence that early treatment may prevent the virus from establishing "reservoirs" of HIV-infected cells in the body. |

Cardiac Arrest Survivors Have Better Outlook Than Doctors Think Americans who suffer cardiac arrest in a hospital and are resuscitated have a 60 percent chance of being alive a year later, authors of a new study found. They also have a 45 percent chance of living for three years — better than the odds of surviving cancer. |

Why Relatives Should Be Allowed To Watch CPR On Loved Ones Researchers in France and the U.S. say watching a resuscitation attempt doesn't have lingering bad effects on relatives — it can actually be beneficial for them. But a researcher says there will be pushback on the practice from U.S. medical personnel because of their fear of being sued. |

Aspirin Vs. Melanoma: Study Suggests Headache Pill Prevents Deadly Skin Cancer Women who took aspirin at least a couple of times a week for five years or more cut their risk of melanoma by 30 percent. The new study adds to the mounting pile of research suggesting that cheap, common aspirin lowers the risk of many cancers, including colon, breast, esophagus, stomach, prostate, bladder and ovarian cancer. |
