The application of a new, precise way to turn genes on and off within cells, described online October 9, 2014 in two articles in the journal Cell, is likely to lead to a better understanding of diseases and possibly to new ...

Many beekeepers feed their honey bees sucrose or high-fructose corn syrup when times are lean inside the hive. This practice has come under scrutiny, however, in response to colony collapse disorder, the massive—and as ...

Reprogramming a cell to express a foreign gene is relatively straightforward. However, reprogramming a cell to express multiple foreign genes is far more complex, especially if trying to exert control over the interplay between ...

Contrary to what was thought, sequences of DNA called enhancers – which control a gene's output – find their targets long before they are activated during embryonic development, scientists at the European Molecular Biology ...

Johns Hopkins biologists have discovered that when biological signals hit cells in rhythmic waves, the magnitude of the cells' response can depend on the number of signaling cycles—not their strength or duration. Because ...

Every cell in our body has exactly the same DNA, yet every cell is different. A cell's identity is determined by the subset of genes that it activates. But how does a cell know which genes to turn off and which to turn on? ...

It is well known that genes are passed from one generation to the next. In addition, new genes arise regularly, although the number of genes in a particular organism does not seem to increase. The paradox has been solved ...
