UCLA study finds genetic link between misery and death

UCLA researchers have discovered what they describe as a biochemical link between misery and death, and in addition found a specific genetic variation that seems to break that link. Additionally, they have developed a computer model of gene-environment interactions to more efficiently probe the “genetic haystack.”

New clues found linking larger animals to colder climates

A pair of University of Houston researchers found a possible new solution to a 163-year-old puzzle. Ecological factors can now be added to physiology to explain why animals grow bigger in the cold. Their results were published in the February issue of the American Naturalist, offering new insight to Bergmann’s rule that animals grow larger at high, cold latitudes than their counterparts closer to the equator, hypothesizing that better food makes high-latitude animals bigger.

Stem cells restore sight in mouse model of retinitis pigmentosa

An international research team led by Columbia University Medical Center successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa. This strategy could potentially become a new treatment for retinitis pigmentosa, a leading cause of blindness that affects approximately one in 3,000 to 4,000 people, or 1.5 million people worldwide. The study appears online ahead of print in the journal Transplantation.
