What the flu does to your body, and why it makes you feel awful
Every year, from 5 to 20 percent of the people in the United States will become infected with influenza virus. An average of 200,000 of these people will require hospitalization and up to 50,000 will die. Older folks over the age of 65 are especially susceptible to influenza infection, since the immune system becomes weaker with age. In addition, older folks are also more susceptible to long-term disability following influenza infection, especially if they are hospitalized.

Viruses that infect bacteria abound in bladder
Phages—viruses that infect bacteria—are abundant in the bacteria that inhabit the female bladder. This is good news, because phage could be used as alternative treatment when antibiotics become resistant to pathogenic bacteria. The research is reported this week in the Journal of Bacteriology, a publication of the American Society for Microbiology.

In pursuit of a universal flu vaccine—study shows pros, cons for major strategy to create broadly protective shot
Flu shot season is here. But as you head to the doctor's office or pharmacy to get vaccinated, scientists are working to make this yearly ritual a thing of the past. Researchers around the world, including at the University of Rochester Medical Center (URMC), are pursuing a "universal" flu vaccine, one that would protect against most or all seasonal and pandemic strains of the flu virus.

New study suggests 21 percent increase in childhood peanut allergy since 2010
Parents often worry about peanut allergies because the reaction to peanuts can be very severe. New late-breaking research being presented at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting suggests that peanut allergy in children has increased 21 percent since 2010, and that nearly 2.5 percent of U.S. children may have an allergy to peanuts.

Alzheimer's gene poses both risk and benefits
Scientists drilling down to the molecular roots of Alzheimer's disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person's risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system's ability to protect the brain from amyloid beta, a key protein associated with Alzheimer's.
