Liping Zhao, Jeremy K. Nicholson and colleagues explain that human beings have been called "superorganisms" because their bodies contain 10 percent human cells and 90 percent microbes that live mainly in the intestines.
"Super" in that sense means "above and beyond." Scientists thus are viewing people as vast ecosystems in which human, bacterial, fungal and other cells interact with each another. Microbes, for instance, release substances that determine whether human genes turn on or off and influence the immune system's defenses against disease. And populations of microbes in the body change with changes in diet, medications and other factors.
"This superorganism view of the human body provides a complete new systems concept for managing human health at the clinically relevant whole body level," say the authors. They term it "one of the most significant paradigm shifts in modern medicine." The article describes how this revolutionary change is fostering emergence of an approach called "functional metagenomics" for developing new medicines.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
