Harvard study suggests racial tension may stem from fear of exposure to infectious diseases

A postdoctoral fellow working in the lab of Psychology Professor Matt Nock,Brian O’Shea is the lead author of a study that suggests racial tension may stem not from different groups being exposed to each other, but fear of a different sort of exposure — exposure to infectious diseases. The study is described in a July 15 paper published in Social Psychological and Personality Science.

Higher consumption of sugary beverages linked with increased risk of mortality

A long-term study, led by the Harvard T.H. Chan School of Public Health, found that the more sugar-sweetened beverages people consumed, the greater their risk of premature death — particularly death from cardiovascular disease, and to a lesser extent from cancer.

Anti-aging research: ‘Prime time for an impact on the globe’

Research into extending humanity’s healthy lifespan has been progressing rapidly in recent years. In February, a group of aging and longevity scientists founded a nonprofit to foster the work and serve as a resource for governments and businesses looking to understand the potentially far-reaching implications of a population that lives significantly longer, healthier lives.

Harvard researchers explore macular degeneration through a new lens

Researchers have created the first cellular atlas of the primate retina and discovered that, while the fovea and peripheral retina share most of the same cell types, the cells are in different proportions, and show different gene expression patterns.

Three years after undergoing gene therapy, his ‘last shot’ hit the target

Three years after undergoing gene therapy at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center to treat a life-threatening immune disorder, an Ohio college student is no longer thinking about his own “last shot” for health, but rather about medical school and “giving back.”
