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.

          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.

            Not even an applicable anaology when we’re breeding and slaughtering rats on a mass scale. It’s not the difference choosing between the life of a rat and the well-being of a human. Animal testing is generally not even applicable to humans and just results in large amounts of death and suffering. Not even to mention the grotesque method artificial insemination of rats. We have better alternatives to animal testing like in vitro, animal testing is not necessary

      I genuinely don’t want to be hateful, but how do you expect stuff like this to be tested without hurting “some” animals. I’m not saying I agree with animal testing and if possible I’d rather them test it another way, but I do understand the importance of it. Without this lot’s of medications and treatments wouldn’t exist.

          In vitro cell cultures don’t have spinal cords. For stuff like this, you need the living animal. Also, fun fact, in order to aquire the cells to culture, you need to kill newborn rats.
