A bit of confusion in the SARS-CoV-2 variant space as of late, since we think that the CDC variant tracker might be plagued by a few issues - which also extends to e.g., wastewater surveillance:

1. XFC is not a rising variant - XFG is 📈
2. LP.8.1 likely <50%, not ~75%, and 📉
3. NB.1.8.1 also 📈

The NSF Is Being Dismantled — With Broad Implications For The American Economy The economic consequences of cuts to the National Science Foundation and restricting scientific inquiry on this scale could be far-reaching.

“Science policy is not just about managing budgets - it is about shaping the future”. Never did I think a Forbes article would explain the dismantling of the NSF so clearly and expansively (beyond economics). The loss is profound, and for some of us, Earth-shattering.
