  1. Re:The challenge on Making Babies In Space May Not Be Easy · · Score: 1

    The first difference between a clinostat and zero G is shear force. In a clinostat, the cells, or embryos, or whatever, are perpetually falling through the liquid medium. They don't settle because the viscous fluid forces counter the gravitational force.

    The second difference is that the cells, or embryos, or whatever, never get to adhere to a surface. For most cells, adhesion forces are 100-1000x gravitational forces and really important. Non-adherent cells undergo anoikis.

    Clinostat is a good model of zero-G for certain situations, but like all experimental models, you have to understand the differences between your model and the real thing

According to the census bureau, in 1967, an income of $19k would put you in the top 5% of households, equivalent to $180k today. By wild extrapolation, you might imagine the 90% tax rate to start around $3.6-4m today.

    Part of this is because of the statistical modeling associated with these studies. It's relatively easy to be certain, and to prove, that the observations from two groups are different: this is the type I error everyone loves. We've all agreed that we're willing to accept a 1-5% probability that we're wrong, so once you hit that statistical threshold, you satisfy reviewers.

The only thing you can formally test is whether the difference between two groups is smaller than some pre-defined margin, but there's no established formalism for choosing how big that margin is. Even worse, there's no established criterion for how frequently you're willing to make a type II error. Some folks design their studies with 10% margin, but this number has a huge influence on the required sample size, and folks often use 20% as a desired power. Worse, many studies get started with no formal statistical design at all, and this more-or-less prevents them from making any meaningful statement of "sameness" between groups.

    It's a shame, because it almost certainly means that a lot of scientists spend a lot of time reproducing experiments that other people already know aren't going to produce any meaningful differences.
