Bacteria reveal strong individuality when navigating a maze

Researchers from ETH Zurich demonstrate that genetically identical cells exhibit differing responses in their motility towards chemical attractants. Average values hide the full picture when it comes to describing the behavior ...

Embryos remember the chemicals that they encounter

We all start out as a clump of identical cells. As these cells divide and multiply, they gradually take on distinct identities, acquiring the traits necessary to form, for instance, muscle tissue, bone, or nerves. A recent ...

Cells that change jobs to fight diabetes

Diabetes is characterized by persistent high blood sugar levels that occur when certain cells in the pancreas—the insulin-producing β cells—are destroyed or are no longer able to secrete insulin. Researchers at the University ...

Chance determines cell death or normal sugar consumption

Some cells fail by chance, and not due to a genetic defect, to properly initiate the molecular processes for the breakdown of sugar. These cells are unable to grow and subsequently die. This discovery was done by a multidisciplinary ...

How birds become male or female, and occasionally both

The highly unusual "semi-identical" Australian twins reported last week are the result of a rare event. It's thought the brother and sister (who have identical genes from their mother but not their father) developed from ...

Cells find their identity using a mathematically optimal strategy

Organisms are made of many types of cells arranged in a precise and reproducible spatial pattern that gives rise to properly formed and well-functioning tissues and organs. But how do genetically identical cells in an organism ...
