A long-standing medical discussion about how transplanted organs survive in a new body has received provocative new evidence from Mayo Clinic research. It shows a donated kidney survives in a new body by turning on a protective mechanism to shield it from the hostile environment of the patients immune system. The results are published in this months American Journal of Transplantation.
Says Mark Stegall, M.D., head of the transplant team that studied kidney genes response to transplantation, "The big question has always been: Why dont the antibodies injure the kidney? Our study begins to show one possible reason for that -- theres a protective mechanism at work."
In the study, the Mayo Clinic team analyzed which genes are turned on during the biological phenomenon known as "accommodation" -- the process by which a transplanted organ adapts to the new environment of the donors body. Accommodation was first described 20 years ago by Jeffrey Platt, M.D., a Mayo Clinic transplant biologist and co-author of this current Mayo Clinic study.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
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...
