Electron microscope images reveal how cells absorb a vital mineral

Columbia University Medical Center (CUMC) researchers have obtained the first detailed snapshots of the structure of a membrane pore that enables epithelial cells to absorb calcium. The findings could accelerate the development ...

New sensor measures calcium concentrations deep inside tissue

Key processes in the body are controlled by the concentration of calcium in and around cells. A team from the Technical University of Munich (TUM) and the Helmholtz Zentrum München have developed the first sensor molecule ...

Ambush in a petri dish

If green algae of the species Chlamydomonas reinhardtii meet Pseudomonas protegens bacteria, their fate is sealed. The bacteria, measuring only some two micrometres, surround the algae, which are around five times larger, ...

Cell signals that trigger wound healing are surprisingly complex

In a sharp and pointy world, wound healing is a critical and marvelous process. Despite a tremendous amount of scientific study, many outstanding mysteries still surround the way in which cells in living tissue respond to ...

Making spines from sea water

Some sea creatures cover themselves with hard shells and spines, while vertebrates build skeletons out of the same minerals. How do these animals get the calcium they need to build these strong mineral structures? Professors ...

Calcium aids chromosome condensation prior to cell division

Osaka University-led Japanese research reveals role for calcium ions in chromosome condensation during mitosis; high-resolution imaging of living cells reveals compact, globular chromosomes in the presence of calcium that ...

An amino acid controls plants' breath

Plants breathe and "sweat" through stomata, microscopic pores found on leaves, stems and other plant organs. Through the stomata, plants take up carbon dioxide for photosynthesis and breathe out the products of this process, ...
