DailyDirt: Matchmaker, Matchmaker, Make Me A Match...
from the urls-we-dig-up dept
Sometimes extending a person's life requires an organ transplant, but it's not exactly easy to find a replacement organ -- especially when donors don't have spares. Medicine is getting better at growing some replacements, so maybe someday patients won't need to rely on other people dying to get a heart, liver, pancreas, etc.- The 2012 Nobel prize for economics went to Alvin Roth and Lloyd Shapley for their work on matchmaking solutions that have practical applications in finding kidney donors and pairing medical students with training programs. The organ donor marketplace has benefited greatly from marketplaces that don't depend on prices -- but still create fair exchanges. [url]
- Why do some organs like kidneys and lungs come in pairs, but others like hearts and livers don't? If you're expecting a real answer to this question (other than dual organs are advantageous for survival in some cases and not in others), keep waiting, but it's interesting to know that hearts in some animals, like amphibians, could be doubled, but they merge to form a single heart.

- Researchers are growing mini-organs, aka organoids, from stem cells -- small brains, eyes, livers and more. These organoid banks for semi-developed body parts could provide extremely good testing environments for pharmaceuticals and medical treatments, replacing lab rats or healthy volunteers. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

So if there is backflow or something then the setup isn't correct.

What makes you say that? It works on a small enough scale to make geckos' feet stick to things, and that's a lot smaller than a heart.

Let's bask in the light that was Chev Chelios and ponder how he could survive a drop from 30,000 feet and land on a car and survive, then an hour later, after conquering electricity, and multiple kung-fu gangsters, shag Amy Smart in front of 50,000 people at a sports stadium, fight multiple dog owners AND their dog, dodge bullets and survive car crashes, then recover his heart by a roof-top battle from Chinese goons by means of a sex-maniac, drug-addicted, highly unsanitary, struck-off doctor.
How? He's Chev Chelios, that's how.

I'm not so sure, it seems like there are a lot of systems that would need to be fully in place before an organism could rely on them. Lungs for example. You can't wander around for long on land without lungs, and there's no time to evolve them in a single generation. Yet somehow animals evolved lungs and discarded their gills. I imagine the same sort of process could manage multiple pumps, and apparently it has:
