Experts warn of synthetic 'bioweapons' danger
(HealthDay)—The burgeoning field of "synthetic biology" research could lead to the creation of dangerous new bioweapons, and U.S. defense officials need to be alert to assess the potential threat.

Food allergy is linked to skin exposure and genetics
Infant and childhood food allergy, whose cause has long been a mystery, has now been linked to a mix of environmental and genetic factors that must coexist to trigger the allergy, reports a new Northwestern Medicine study.

Discovery reveals way to stop inflammation in Alzheimer's, arthritis, more
A new discovery about the immune system may allow doctors to treat harmful inflammation that damages the brain in neurodegenerative diseases such as Alzheimer's. It might also let doctors save patients from the potentially deadly inflammation of sepsis, a full-body infection that kills a quarter-million Americans every year.

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.

Obesity can add five weeks of asthma symptoms per year in preschoolers
Asthma affects almost 1 in 10 children in the U.S. and is a leading cause of emergency room visits and hospitalizations in preschoolers. According to new research from Duke Health and collaborators, symptoms may be worse for children ages 2 to 5 who are overweight.

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.

Scientists discover rare genetic susceptibility to common cold
Scientists have identified a rare genetic mutation that results in a markedly increased susceptibility to infection by human rhinoviruses (HRVs)—the main causes of the common cold. Colds contribute to more than 18 billion upper respiratory infections worldwide each year, according to the Global Burden of Disease Study .

Team finds another immune system link science said didn't exist
The University of Virginia School of Medicine has again shown that a part of the body thought to be disconnected from the immune system actually interacts with it, and that discovery helps explain cases of male infertility, certain autoimmune diseases and even the failure of cancer vaccines.

AAAAI: early-life secondhand smoke may up food allergy risk
(HealthDay)—Exposure to secondhand smoke in the first few weeks of life could increase the risk that children will develop food allergies, according to research presented at the annual meeting of the American Academy of Allergy, Asthma & Immunology, held from March 3 to 6 in Atlanta.

AAAAI: asthma more likely to prove fatal in black children
(HealthDay)—Black American children are six times more likely to die from asthma than their white or Hispanic peers, according to research presented at the annual meeting of the American Academy of Allergy, Asthma & Immunology, held from March 3 to 6 in Atlanta.

AAAAI: low vitamin E in mothers can up asthma risk in offspring
(HealthDay)—Children born to mothers with low levels of vitamin E might be more likely to develop asthma, according to research presented at the annual meeting of the American Academy of Allergy, Asthma & Immunology, held from March 3 to 6 in Atlanta.

Treatments better than antibiotics needed now
New Zealanders should not be complacent because we have fewer antibiotic-resistant bacterial pathogens than elsewhere in the world, a University of Otago expert says.
