A collaboration between Johns Hopkins and Massachusetts Institute of Technology scientists has mathematically demonstrated that a national matching program for kidney paired donation, also called paired kidney exchange, would ensure the best possible kidney for the greatest number of recipients who have incompatible donors. Kidney paired donation (KPD) provides organs to patients who have a willing, designated donor who is not compatible. A kidney from such a donor is matched to -- and transplanted into -- the recipient of a second incompatible donor-patient pair, and vice versa. The transplants are performed simultaneously.
The researchers have developed an interactive Web site, www.OptimizedMatch.com, that provides more details and interactive demonstrations of the algorithm and its use in transplantation.
"Our findings demonstrate that a national pool of kidney donors and recipients, combined with new mathematical techniques for sorting through them to find the best possible organ matches, will not only allow more people to get the transplants they need, but will dramatically cut health care costs, reduce disruptive and unnecessary travel for patients, and insure that transplanted kidneys have the best possible chance of survival," said Dorry L. Segev, M.D., a surgeon at Johns Hopkins and lead author of a report published in the April 20, 2005, issue of the Journal of the American Medical Association.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
