Below is the cumulative amount of progress from first grade to twelfth by percentile: As you can see there is a lot of progress for the best students into and throughout high school. The students in the first percentile don't meaningfully improve their scores after fifth grade.

Two bits of good Covid news today in the UK. First, adding another two weeks of ONS data means Covid’s infection fatality rate has now crossed below the "2x flu" line. Latest IFR is roughly 60% higher than flu and still falling.

These epidemics have proceeded in a similar fashion across states with initial rapid exponential growth that slowed as epidemics grew in size. It appears that states are largely on the same curve, just some are farther ahead on this curve compared to others. 4/9

Fig 5B: repeat w/ live Omicron previous pseudotype study findings that Om does not induce cell syncytia (cell-cell fusion, which is highly pathogenic/inflammatory). Fig 5D: confirm much reduced lung epithelial replication (an order of magnitude). All-in-all Om looks distinct.
