Finding a cell's true identity

Scientists have long sorted cells into different varieties based on their appearance under a microscope or, for differences that are more visually subtle, based on the behavior of a handful of genes. But in a bid to reveal ...

Research may point to new ways to deliver drugs into bacteria

An exhaustive look at how bacteria hold their ground and avoid getting pushed around by their environment shows how dozens of genes aid the essential job of protecting cells from popping when tensions run high.

New method opens the door to efficient genome writing in bacteria

Biological engineers at MIT have devised a new way to efficiently edit bacterial genomes and program memories into bacterial cells by rewriting their DNA. Using this approach, various forms of spatial and temporal information ...

How a cell knows when to divide

How does a cell know when to divide? We know that hundreds of genes contribute to a wave of activity linked to cell division, but to generate that wave new research shows that cells must first grow large enough to produce ...

Proteins use a lock and key system to bind to DNA

You can think of DNA as a string of letters—As, Cs, Ts, and Gs—that together spell out the information needed for the construction and function of cells. Each cell in your body shares the same DNA. So, for cells to take ...

New training platform for big data analysis

Studies indicate that more than 95 percent of researchers in the life sciences are already working with big data or plan to do so—but more than 65 percent state that they only have minimal knowledge of bioinformatics and ...
