h7n9 Influenza Is Both Lethal and Transmissible in Animal Model for Flu

In 2013, an influenza virus that had never before been detected began circulating among poultry in China. It caused several waves of human infection and in late 2016, the number of people to become sick from the H7N9 virus suddenly started to rise. As of late July 2017, nearly 1,600 people had tested positive for avian H7N9. Nearly 40 percent…

Common Antiseptic Ingredients De-Energize Cells and Impair Hormone Response

A new in-vitro study by University of California, Davis, researchers indicates that quaternary ammonium compounds, or “quats,” used as antimicrobial agents in common household products inhibit mitochondria, the powerhouses of the cell, as well as estrogenic functions in cells. Their findings appear online today (Aug. 22) in Environmental Health Perspectives, a publication of the National Institute of Environmental Health Sciences. Quats are…

Researchers Discover What May Be Earliest Stage of Alzheimer’s

Older adults with elevated levels of brain-clogging plaques — but otherwise normal cognition — experience faster mental decline suggestive of Alzheimer’s disease, according to a new study led by the Keck School of Medicine of USC that looked at 10 years of data. Just about all researchers see amyloid plaques as a risk factor for Alzheimer’s. However, this study presents…

Biochemists Develop New Way To Control Cell Biology With Light

Researchers at the University of Alberta have developed a new method of controlling biology at the cellular level using light. The tool—called a photocleavable protein—breaks into two pieces when exposed to light, allowing scientists to study and manipulate activity inside cells in new and different ways. “By shining light into the cell, we can cause the photocleavable protein to break,…
