In a new study in mice, a team of researchers from UCLA, the Swiss Federal Institute of Technology, and Harvard University have uncovered a crucial component for restoring functional activity after spinal cord injury. The neuroscientists have shown that re-growing specific neurons back to their natural target regions led to recovery, while random regrowth was not effective.

      Animal testing has saved the lives of millions and improved billions. It’s gruesome, but necessary. Especially for research like this.

      It does make you wonder what caused spinal injury in these mice. I do not suppose there is a sufficient natural supply of these kinds of injured mice.

      But, if not animal testing, how do you propose to develop the treatment?

        It’s a little grim, but there’s a standard SCI (spinal cord injury) guillotine that drops a weight with an angled wedge to cause a near perfectly replicable SCI. The mouse is sedated, but it’s not exactly a good time for the mouse.

        But yeah, the alternative is testing on humans, which, I really don’t think we need a reminder on why that’s super illegal.

      People who value the lives of small rodents over the lives of fellow human beings should have their heads checked, because their moral compass is seriously out of whack.

        It’s more than just some “rodents.” Humans dont stop. It goes from “rodents” to bigger animals and eventually human testing when we already have alternatives like in vitro. They mass breed these animals with artificial insemination only to kill them in the end, even if they are perfectly healthy after the testing. It’s unnecessary and cruel. We’re talking on a grand scale, billions to trillions over the years have died for tests that often aren’t even applicable to humans. Animal testing should be abolished, humans are horrific for their actions. We’ve even taken brains of mice and made it so they can move tiny cars back and forth. Their whole consciousness reduced down to moving forward and backwards in a toy car. Absolutely barbaric.

          You’re making it sound like they did it for funsies, rather than important research. Also, link please, this sounds like a massive breakthrough.
