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.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
