How proteins find their place in the cell

Over a quarter of all proteins in a cell are found in the membrane, where they perform vital functions. To fulfill these roles, membrane proteins must be reliably transported from their site of production in the cell to their ...

Reproduction key to maintenance of marimo shape

The marimo is the aggregative form of the freshwater alga Aegagropila linnaei. In Japan, Lake Akan in Hokkaido is the best known habitat of the marimo. It is so emblematic of the lake and surrounding region that it has been ...

Rhizobium adapts lifestyles from rhizosphere to symbiosis

Rhizobia are soil-dwelling bacteria that form symbioses with legumes and provide biologically useable nitrogen as ammonium for the host plant. During symbiosis, rhizobia must adapt to several different lifestyles. These range ...

Cell membranes in super resolution

Expansion microscopy (ExM) enables the imaging of cells and their components with a spatial resolution far below 200 nanometres. For this purpose, the proteins of the sample under investigation are cross-linked into a swellable ...

Cancer cells 'remove blindfold' to spread

Cancer cells spread by switching on and off abilities to sense their surroundings, move, hide and grow new tumors, a new study has found.

Plants on aspirin

When pathogens enter a plant, infected cells set off an alarm before they die. They discharge methylsalicylic acid, which is later transformed into salicylic acid, triggering an immune response. Hence, salicylic acid is a ...

Watch immune cells dig tunnels in tissues

White blood cells called cytotoxic T lymphocytes (CTLs) dig tunnels in tissues, potentially allowing other CTLs to quickly reach infected cells and tumor cells, researchers report December 1st in Biophysical Journal. The ...
