Ten years ago, leaders in the field of toxicology called for a transformation of the discipline to incorporate advances in biotechnology and predictive methodologies into alternative testing strategies. But a decade later, the outcomes of these efforts are not well understood.
In research that potentially could delay the onset of Parkinson’s disease, Alzheimer’s disease, cancer, stroke, cardiovascular disease, and other diseases of aging, biologists have produced a genetic one-two punch that significantly slowed aging and improved health in the middle-aged fruit flies they studied.
In a study analyzing the genomes of 210,000 people in the United States and Britain, researchers have found that the genetic variants linked to Alzheimer’s disease and heavy smoking are less frequent in people with longer lifespans, suggesting that natural selection is weeding out these unfavorable variants in both populations.
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.
A new study by UCLA researchers reveals the range of reactions — from rejection to reinterpretation to acceptance — after white nationalists learn that DNA ancestry test results indicate they may not be as white or European as they previously thought.
This paper considers the emergence of new forms of race-making using a qualitative analysis of online discussions of individuals’ genetic ancestry test (GAT) results on the white nationalist website Stormfront.
