Epigenetics is the science of living DNA, charting the chemical pathways that spur DNA into action by turning genes on and off. While the Human Genome Project of the early 2000s was hailed as the key to understanding human heredity and disease, that historic effort was just the beginning. It has taken epigenetics to fill in the picture, explaining how the fixed code of our genome is implemented in countless living processes.

The proliferation of social media platforms and our increasing reliance on the internet for connection and communication has caused the line between the “real” world and the online world to blur. So much of our lives can be impacted by online interactions—and not all those interactions are positive. Why does the internet seem to encourage bad behavior from some users? Why do we feel we need to share so much of our private lives with the online world? Is screen time really as addictive as the headlines say?

As recently as 1990, it seemed plausible that the solar system was a unique phenomenon in our galaxy. Thanks to advances in technology and clever new uses of existing data, now we know that planetary systems and possibly even a new Earth can be found throughout galaxies near and far.
