Scientists regenerate neurons that restore walking in mice after paralysis from spinal cord injury::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.

Fuck animal testing

[–] [email protected] 20 points 1 year ago

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.

This is a remarkably specific and disturbing fact. Thank you for sharing.

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.
