Genetic engineering: The future of foods?
Hawaiian farmers were in trouble. In the mid-1990s, an insect-borne virus--the papaya ring spot virus (PRSV)--threatened to decimate Hawaii's second-largest fruit crop. Plant breeders scrambled to produce a virus-resistant papaya. When traditional plant breeding methods failed, researchers turned to genetic engineering.  more

Orphan products: Hope for people with rare diseases
An orphan disease is defined as a condition that affects fewer than 200,000 people nationwide. This includes diseases as familiar as cystic fibrosis, Lou Gehrig's disease, and Tourette's syndrome, and as unfamiliar as Hamburger disease, Job syndrome, and acromegaly, or "gigantism." Some diseases have patient populations of fewer than a hundred. Collectively, however, they affect as many as 25 million Americans, according to the National Institutes of Health (NIH), and that makes the diseases--and finding treatments for them--a serious public health concern.  more

Long-term follow-up of mortality in patients with community-acquired pneumonia
A new study shows that patients who recover from community-acquired pneumonia (CAP) experience an increased risk of death even up to 5 years after recovery compared to age-matched controls.  more
