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. After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

    Hmm

    It's not too hard to guess at why you only have one heart. It's a pump and a circulatory system. If you had TWO pumps, odds are good one would be stronger than the other. A stronger pump means a possibility of backflow on the weaker pump, and backflow on blood means blood clots, which means death. So having two hearts means an elevated chance at embolisms and less chance of surviving.

      Be careful of the assumption that a biological system is in any way intelligently designed.

        Top banana! Chev Chelios IS that balls out urban ranger!!! The Staph at that zenith before he started shagging RHW, going to Kew Gardens and being seen at Crufts. Are you doing a poem there Klaus or someting? Wow.

        Oh Wait, your not german are you?

          Please don't dis the Germans. Just, don't. History man

          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.

        Chev Chelios, the man with two hearts, only his real one had been snatched by Chinese mooks leaving him with a mechanical battery operated one

        That said I can only remember Amy Smart----- can you blame me?

      Re: Hmm

      I'm no doctor here but I can assure you that it does not happen with mechanical pumps if properly installed. You can go for added pressure or added flow depending if you install them in series or in parallel. And even then you can add valves to prevent backflow depending on your needs.

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

        Re: Re: Hmm

        Exactly my point. We can tailor a mechanical system with multiple pumps by controlling everything about the system. But who or what is controlling biological systems so finely that they can prevent such problems? I doubt evolution works on such small scales as to alleviate problems, and I don't know about you, but no "higher power" has ever intervened in the lives of anyone I know.

          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.

            Small scale meaning within an organism's lifespan, not size. Evolution takes many generations to work, but you don't have that time to adjust an unbalanced pumping system.

              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:
