Using these engineered proteins, researchers can record histories that reveal when certain genes are activated or how cells respond to a drug. As cells perform their everyday functions, they turn on a variety of genes and cellular pathways. MIT engineers have now coaxed cells to inscribe the history of these […]

Certain T cells can secrete cytokines that are normally part of the innate immune system, as researchers from the Leibniz Institute for Natural Product Research and Infection Biology (Leibniz-HKI) and an international research team discovered. They have thus revealed several previously unknown properties of these immune cells that are relevant […]

Although the human body is externally symmetric across the left-right axis, there are remarkable left-right asymmetries in the shape and positioning of most internal organs including the heart, lungs, liver, stomach, and brain.
