I am curious to hear what HN thinks of calling these things robots. These are frog embryos that have been surgically reshaped and had muscle cells implanted in them.
But one other thing to note here is that these headlines about a "replication crisis" seems to imply that this is a new phenomenon. Let's not forget the history of the electron charge. As Feynman said:
"We have learned a lot from experience about how to handle some of the ways we fool ourselves. One example: Millikan measured the charge on an electron by an experiment with falling oil drops, and got an answer which we now know not to be quite right. It's a little bit off because he had the incorrect value for the viscosity of air. It's interesting to look at the history of measurements of the charge of an electron, after Millikan. If you plot them as a function of time, you find that one is a little bit bigger than Millikan's, and the next one's a little bit bigger than that, and the next one's a little bit bigger than that, until finally they settle down to a number which is higher. Why didn't they discover the new number was higher right away? It's a thing that scientists are ashamed of—this history—because it's apparent that people did things like this: When they got a number that was too high above Millikan's, they thought something must be wrong—and they would look for and find a reason why something might be wrong. When they got a number close to Millikan's value they didn't look so hard. And so they eliminated the numbers that were too far off, and did other things like that ..."

Perhaps the most interesting point is the discussion of the furin cleavage site.
In contrast, fans have been fine with the goal-line technology, which gives decisive (usually) and quick results.
The use of AI in this paper seems more relevant for setting team strategies and picking players rather than enforcing rulings.

> Why the difference in price between Deluxe Individual Kits and Classroom Kits?
>Our mission is to bring bring affordable scientific tools to everyone (not just communities who have the resources - but everyone). For any of this to be possible, our business model balances our cost of operations with offering extremely low-cost (low-profit) products.
>We find this balance through a pricing structure that operates on a 2-tier system: high price point kits for individual Foldscopes (Deluxe Individual Kits), and low price point kits for bulk Foldscopes (Classroom Kits).
>We arrived at this pricing structure for many reasons, but primarily because the reality of fulfillment and shipping means we cannot ship a single Foldscope that costs roughly $1 in parts to produce at a $1 dollar price while being sustainable. Overall, we make a profit only from our high price point kits, this profit allows for us to exist and produce any microscopes at all, and this profit also subsidizes our low price point kits (which we do not profit off of), in which offer Foldscopes for as inexpensive as $1.75 each!
It seems that the incentive of a journal is to maintain an appearance of legitimacy, rather than actually enforcing it. This is why, as the article mentions, journals tend to be fairly quiet about retractions and issues of misconduct.
There is a better incentive by those that are funding the research (the taxpayers/government) that their investments are resulting in legitimate works. This also goes in line with the idea that these final manuscripts should be freely available to the public. Now with that said, I also acknowledge that the idea of having the NIH, NSF. etc. operate the editorial and review process would be nightmarish.
I don't believe that most modern physicists dispute that the equations we use are anything more than models. For example, you won't go to a seminar on microrheology and have a physicists point out in disgust that the presented derivation is "wrong" because it used Newton's second law without the relativistic component. While this is perhaps an extreme example, it is the case that we often have to ignore certain effects/make certain assumptions to make equations solvable and interpretable. If we believed that our physics equations represented some "absolute truth," then we would never allow ourselves to make these sort of assumptions in the formulas we derive.
