An EPFL (Ecole Polytechnique Federale de Lausanne) team led by professor Melody Swartz has demonstrated for the first time that the presence of very slow biological flows affects the extracellular environment in ways that are critical for tissue formation and cell migration. Their results will appear online the week of October 24 in Proceedings of the National Academy of Sciences.
A major challenge for tissue engineering is to identify the essential environmental ingredients that cells need in order to communicate, migrate, and organize into living tissues. One of these ingredients is the presence, outside the cell, of minute changes in the concentration of special proteins called morphogens. Cells can sense even the tiniest differences in morphogen concentration and will alter their functions accordingly. In embryonic development, stem cells differentiate into organs by means of the actions of morphogens. And even cancer cells can use morphogens to grow, induce a blood supply, and metastasize.
Although the concept of cell organization in response to these morphogen gradients is well documented, little is known about how these subtle concentration changes get established the first place, particularly within the dynamic environment of a real tissue. This research provides evidence that tiny biophysical forces in the extracellular environment may play an important role.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
