Right now, there are more than 70,000 people on the waiting list
for a kidney transplant in the US alone. Sometimes, a family member will offer to donate a kidney to a relative. That's a really amazing thing to do. The problem is that one-third of the time, the match isn't right. But what if the donor, say, from one family, is a good match for the recipient in another family, and vice versa? According to Science News, researchers at the United States Naval Academy and Johns Hopkins University hope to address this with a mathematical method to "match up the maximum number of donors with recipients while simultaneously guaranteeing high compatibility in each case." The technique is based on graph theory
, a way to model the relationship between pairs of objects. From Science News:
(US Naval Academy mathematician Sommer) Gentry expects that if there were a national registry in place for kidney matching, and if it used her team's method, then each month, about half the pairs in the registry would find a compatible match. Each year, 1,000–2,000 patients would get kidneys who currently would not.
By contrast, as of 2005, only 51 patients had ever received kidneys through a swap in which two incompatible pairs exchange donors to create compatible pairs. Gentry calculates that developing a national registry could save $750 million per year, because dialysis, the only alternative to transplantation, is very expensive.

We just got the Sport model of the EPIKGO hoverboard at my office. Besides being terribly chic, it’s apparently bulletproof.
Ok, it’s not just solar powered. It’s also an anti-theft, waterproof marvel that keeps my phone’s power bar from ever getting into the red.Sure the idea seems obvious now – tuck a gigantic solar powered battery pack into an exposed slot and turn the wearer into a walking energy harvester. Simple maybe, but I didn’t […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
