Scientists do repeat experiments, they just don't publish the results because no one cares.

Specifically, results are replicated wherever you want to build on something someone has done. For example I'm making specific glass off of a Nature paper for a totally unrelated use.

If the glass doesn't work out will I publish my results? No, too much work to get rejected.

yes, you want to test your Alzheimer treatment, and you measure the amyloid in the patients before the treatment, and you don't find it in some patients... Are you not going to publish that?

To be clear, science is a shit show. Especially biology.

That being said, it's not true that we don't replicate results. We don't intend to, and we don't do it for the sake of replication, but as a matter of conducting experiments we do a lot of replicating.

And negative results are just thrown out.
