They say what doesn’t kill you makes you stronger, and this applies just as well to infectious diseases. Antibiotics have revolutionized medicine and dramatically increased human life expectancy, but we are in the midst of a post-antibiotic era. Many drugs that used to be effective against infections are becoming…

Cars are everywhere. They are essential for our day to day lives, but these vehicles are a double-edged-sword. Cars emit exhaust gases, and those gases contain hydrocarbons. These molecules, as their name suggests, contain both carbon and hydrogen atoms. Hydrocarbons from cars result from gas that has not been…

New findings by scientists at the University of California, Santa Cruz, suggest that an evolutionary arms race between rival elements within the genomes of primates drove the evolution of complex regulatory networks that orchestrate the activity of genes in every cell of our bodies. The arms race is between mobile DNA…

As scientists catalog the trillions of bacteria found in every nook and cranny of the human body, a new look by the University of Michigan shows wide variation in the types of bacteria found in healthy people. Based on their findings in today’s Nature, there is no single healthy microbiome or microbe community.…
