If you are submitting an NIH grant in February, you will be required to use SciENcv to prepare you biosketch. IT IS MUCH WORSE THAN YOU CAN POSSIBLY IMAGINE. Set aside *at least* 4 hours just to transfer an existing an biosketch into SciENcv.

”replication crisis” has always been hyperbole. Scientists ALWAYS argued, called each other frauds, and eventually land on consensus. A lot of what van Leeuwenhoek observed in the late 1600s was NOT REPRODUCIBLE because nobody could make lenses like him. But he was right, about cells, and bacteria.
