Heart pumping machine

Normally, testing out cardiac surgery ideas goes something like this: Let’s say Dr. Robotnik thought up a new technique for repairing heart valves. Before it hits the OR, the technique gets tried out on live pigs. Swine hearts are pretty similar to human hearts, making them the ideal (ahem) guinea pigs. But getting permission for live animal testing is time-consuming and expensive, costing around $2,500 a pop. Perfecting a technique might take a number of trials, which means a number of pigs, more time & money, then PETA gets involved… you get the idea. A real headache. So what’s a surgical innovator to do?

Fake it! A new machine at North Carolina State University takes a dead heart from your local butcher and makes it pump just like the real thing. This way, doctors can test out new tools and techniques for heart surgery without the time and money required for live trials. The machine pumps pressurized saline through the cardiac tissue, making it move in a sort of pig-heart version of Weekend at Bernie’s. All this is controlled by a computer, and even has live cameras to film the action from inside. Plus, the new technique is recession-proof at a cool $25 bucks per trial.

      Greg Cosell: Bryce Young is a complimentary piece

      By *FreeFua* · Posted

      As far as elite/elevate talent QB’s It’s Allen Mahomes Jackson and Burrow that’s it.  Then we have tiers and those can be debated all day Dak is a good QB but I know this board would want him out of Charlotte if he was the QB here. 2 playoff wins in 10 years. Justin Herbert no playoff wins. Threw 4 interceptions in last years playoff game. 23 TD passes last year. 20 the year below and 25 the year before that. This board loves stats without context and these stats aren’t saying they’re much above complimentary  Kyler Murray isn’t good. I’m not sure how he made this list.  Caleb Williams, Trevor Lawrence both benefiting from some real good offensive coaches right now. They’re both complimentary pieces until proven otherwise  I like Jordan Love. Always have. I wanted to draft him but he isn’t a superstar.  CJ Stroud hasn’t been much better than Bryce after his rookie season. After that Bears game year 2 his numbers very similar to Bryce I will say I think Drake Maye is well on his way to becoming the next top tier QB if I had to pick one from this entire list. I’d also say Baker Mayfield is a damn good QB and I’d take him over most of those guys not in the elite category  Now if you want to debate tools and which QB’s possess tools to put them in higher tiers that’s a completely different discussion. Most QB’s on your main list all have those physical tools that will keep you thinking he’ll become the next top tier QB. They’ll sprinkle in a “wow” play or two a game. Bryce will never look that way. Young’s game at its peak will physically always look different and I think that’s where most people struggle when it comes to seeing how Young’s can be successful in the league  All QB’s need a team around them. I think the Bills are failing Josh Allen much like the Panthers did Cam. Beane and McDermott using same blueprint with Bills team. Josh Allen hasn’t had much in terms of WR’s and it’s ultimately costing them when it matters the most
