Researchers develop tool to drastically speed up the study of enzymes

For much of human history, animals and plants were perceived to follow a different set of rules than rest of the universe. In the 18th and 19th centuries, this culminated in a belief that living organisms were infused by non-physical energy or “life force” that allowed them to perform remarkable […]

How promiscuous protein droplets regulate immune genes

Biochemists at Emory are achieving insights into how an important regulator of the immune system switches its function, based on its orientation and local environment. New research demonstrates that the glucocorticoid receptor (or GR) forms droplets or “condensates” that change form, depending on its available partners. Understanding how the GR […]

Study reveals source of remarkable memory of “superagers”

As we age, our brains typically undergo a slow process of atrophy, causing less robust communication between various brain regions, which leads to declining memory and other cognitive functions. But a rare group of older individuals called “superagers” have been shown to learn and recall novel information as well as […]
