Quick! What's 6✖️8?

This heatmap shows the trickiest multiplications for kids aged 5-8.

Love to see a similar study on adults to see how they compare!

The danger of Molnupiravar: extensive evidence of specific #SARCoV2 mutations this drug has induced across the world which can be passed along from people who do not clear the virus

A molnupiravir-associated mutational signature in global SARS-CoV-2 genomes - Nature

A specific class of long phylogenetic branches, distinguished by a high proportion of G-to-A and C-to-T mutations, are almost exclusively found in sequences from 2022, after molnupiravir treatment was introduced, indicating that molnupiravir treatment can give rise to viable mutagenized viruses.

The more we see the hyper-mutated BA.2.86 variant showing up, especially at a time with diminished surveillance, now 6 countries and ~2% from wastewater in 1 Swiss region, the more troubling it looks—not like it's going to fizzle away.

Recent Swiss waste water data is public! One thing missing for waste water has been real-time data sharing similar to allow analysis of multi-country data with a consistent analysis pipeline: think covSpectrum or Nextstrain but for waste water data rather than consensus sequences

What a gorgeous and brilliant but whacko idea by Erik and Martin Demaine 👇🏼
[2304.01393] “Every Author as First Author”
https://arxiv.org/abs/2304.01393
Every Author as First Author

We propose a new standard for writing author names on papers and in bibliographies, which places every author as a first author -- superimposed. This approach enables authors to write papers as true equals, without any advantage given to whoever's name happens to come first alphabetically (for example). We develop the technology for implementing this standard in LaTeX, BibTeX, and HTML; show several examples; and discuss further advantages.

Wenn es das nächste Mal heißt „aber die Rohstoffe“, dann merkt euch diese Zahl: Bis zu 95 Prozent der Komponenten von PV-Anlagen werden recycelt. Besonders absurd ist das Rohstoff-Argument, wenn die Alternative ist, Zeug aus dem Boden zu holen, UM ES ZU VERBRENNEN. https://www.windkraft-journal.de/2023/08/17/solarbranche-wird-zur-kreislaufwirtschaft/191283
Solarbranche wird zur Kreislaufwirtschaft | Windkraft-Journal

(WK-intern) - Wind und Sonne gehört hierzulande die energetische Zukunft. Doch wie gut ist es eigentlich um die Energiebilanz der Anlagen selbst bestellt? Gerade wenn Solarmodule an ihr technisches Ende kommen, sind innovative Lösungen gefragt. Beim Ressourcenmanagement stellt sich die Zukunftsbranche derzeit neu auf. Die Idee der Kreislaufwirtschaft greift immer mehr um sich. Neu ist
