>Cells from a human embryo were grown into a patch that was delicately inserted into the back of the eye. I assume the baby didn't survive the process since there's no mention of that.

It's not a baby, it's an embryo. Lots of embryos don't survive for lots of reasons.

Earlier quoted context omitted.

This is important because, for some, the moral dilemma would preclude this treatment.

It's also important because a baby was killed to give a rich old guy a few more years of sight. A whole new underclass of children worthy of murdering for medical treatment arises.

Do you genuinely believed that a baby was killed to harvest stem cells? If the baby was already dead, are you morally opposed to using an unsaveable baby's stem cells?

I regularly see comments on YC about Signal-to-Noise ratio, and how YC votes are meant to distinguish the "signal" from the "noise", but in this case, it's clear that this isn't what they're being used for. They're being used to enforce a preconceived bias.

Of the two comments that addressed the moral indignity of the treatment (that it requires the death (murder, in most cases) of an innocent human person for its success) they were considered to be "noise".

“He was one of two patients given pioneering stem" I find the tiny test groups in medical ‘research’ so strange.

It's a test to see if they should bother moving forward. You don't want to gear up a big study just to find out that the treatment gives everyone cancer (which is a concern mentioned in the article) or that it doesn't work at all. You do a pilot study to see if there is potential before you waste a lot of work and maybe hurt people. Anyway if the effect size is big enough, you don't need a really large study to get s…

We do the same in web ergonomics. Testing you Ui on 3 people is enough to see the biggest flaws of the tool and engaging in more expenses. See the excellent book "don't make me think" for a quick and efficient write up on the topuc.

Misleading comment. You're talking about murder but this only involved embryos. Many/most people don't consider that murder any more than the spilling of seed is. If you want to push a political view don't couch it as a systemic complaint.

Moral indignity? Murder? Person? It looks like we have vastly different definitions of each of these words. Scaremongering with no basis in reality is closer to noise than it is to signal.

It may be worth knowing that you don't have to kill an embryo each time. Once you've harvested a stem cell line, you can use it repeatedly.

If, at some point in the future, scientists figure out a way to coax normal cells to become totipotent, will you consider amputation as murder?

>Both patients in the trial had "wet" age-related macular degeneration. This form of the disease is caused by abnormal blood vessels growing through the retinal pigment epithelium and damaging the macula. Dry age-related macular degeneration is more common and caused by the retinal pigment epithelium breaking down.

If this is a viable treatment method, it would help only the minority of macular degeration patients.
