| This is perfect clickbait wording
|
| "The Fetus" = "general epithelial cell"
|
| "Helps Repair" = "Follows well understood biochemical processes"
|

|
| The way that it is written implies agency, signal discrimination
| and focused intercession by the "Fetus" which of course is absurd
|
| It's an interesting and novel result, no need to make it seem
| bigger than it is.
|
| Now all that's going to happen is that I'm going to add a
| discount bias to anything coming from these sources and I will
| have reduced my trust in reporting (again) reducing trust overall
|
| Great work folks, you got 1000 more hits on your article while
| undermining science communication again. Worth it?

| That is not true. Bones heal, muscles heal, nerves grow back
| under some circumstances, the central nervous system
| compensates, every tissue fights infections and works hard to
| get rid of toxins where it can. These are all cases of self-
| repair.
|
| Yeah some of these processes result in scarring, some of the
| time. That doesn't mean it is not self repairing. In fact it
| is the result of the self repair!
|
| Sorry that I jump on this, but it is incredible that we are
| all these advanced, beatifull, self-repairing "meat robots"
| and the processes work so smooth that someone doesn't even
| notice all the self repairing which goes on inside their own
| body.
|
| If you are wondering how an organ which stops self repairing
| looks like buy some meat, any meat, from a butcher and put it
| on your kitchen counter. It will within days start to smell
| bad, grow mould, liquify and eventually insects and magots
| will carry it away bite by tiny bite. It happens with the
| meat because it stopped self-repairing. It doesn't happen
| with your flesh because it is constantly self-repairing.

| Yes, under a strict definition those are organs. But under

| typically self-contained and has a specific vital function,
| such as the heart or liver in humans." [1] they are not.
|
| As for the last paragraph, I don't agree "self repairing"
| and "alive" are the same
