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.
The golden age of antibiotics may be drawing to a close. The discovery of E. coli carrying mcr-1 and ndm-5 has left clinicians without an effective means of treatment for the superbug. But, researchers have assembled a team of three antibiotics that, together, are capable of eradicating the deadly bacterium.
The genes that are involved in the development of the fetus are activated in different tissues and at different times. Their expression is carefully regulated by so-called “enhancer sequences” and requires the DNA molecule to loop around and bring them in close proximity to their target genes.
