To protect stem cells, plants have diverse genetic backup plans

Despite evolution driving a wide variety of differences, many plants function the same way. Now a new study has revealed the different genetic strategies various flowering plant species use to achieve the same status quo.

Determining how and why cells make decisions

Cells are constantly making decisions that lead to differentiation. For instance, cells in an embryo make a series of decisions that determine whether they will become neurons in some cases and muscle cells in others. How ...

Unusual protein helps regulate key cell communication pathway

Charged atoms, or ions, move through tiny pores, or channels, embedded in cell membranes, generating the electrical signals that allow cells to communicate with one another. In new research, scientists have shown how an unusual ...

How bacteria defend themselves against plasmas

Plasmas are used in wound treatment against pathogens that are resistant to antibiotics. However, bacteria can defend themselves. They employ a heat shock protein that protects them.

Imaging technique shows molecular machinery at work

New imaging methods that allow researchers to track the individual protein molecules on the surface of cells have been developed by Weill Cornell Medicine investigators. The results offer unprecedented insight into how cells ...

Membrane proteins: Communicating with the world across the border

All living cells are held together by membranes, which provide a barrier to the transport of nutrients. They are also the communication platform connecting the outside world to the cell's interior control centers. Thousands ...
