By identifying a key regulator of cell identity, a team from the UNIGE and the FMI has succeeded in modifying the structure and function of tentacle cells in hydra. Humans, animals, plants: all multicellular organisms are made up of specialized cells called differentiated cells. Thus, the cells that make up […]

Using a specialized MRI sensor, MIT researchers have shown that they can detect light deep within tissues such as the brain. Imaging light in deep tissues is extremely difficult because as light travels into tissue, much of it is either absorbed or scattered. The MIT team overcame that obstacle by […]

The human brain holds many clues about a person’s long-term health — in fact, research shows that a person’s brain age is a more useful and accurate predictor of health risks and future disease than their birthdate. Now, a new artificial intelligence (AI) model that analyzes magnetic resonance imaging (MRI) […]

The unicellular marine organism Salpingoeca rosetta belongs to the group of choanoflagellates. When hunting for bacteria, these protozoa can detect their prey by means of certain signaling molecules. They then form rosette-like multicellular structures to better catch their prey. However, some bacteria produce inhibitors to prevent the formation of the […]

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. Left-right asymmetry is known to be established during early embryogenesis by a small cluster of cells termed […]
