Making systems robust

The human body keeps the calcium concentration in the blood constant, similarly to an aircraft's autopilot keeping the plane at a constant altitude. What they have in common is that both the body and the autopilot employ ...

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 ...

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 ...

Calcium to phosphorus ratio in pig diets established by new study

The amount of digestible calcium included in pig diets has a direct impact on phosphorus digestibility, but the optimum ratio between the two minerals has not yet been found. In a recent study from the University of Illinois, ...

Growth mechanism of fungi decoded

Fungi grow with tubular cells extending by kilometers. Growth takes place exclusively at the tip. Researchers of Karlsruhe Institute of Technology (KIT) have now found out how this works: Construction materials are transported ...

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, ...
