🧡 : this the first in a series of that will eventually be stitched together into a related to πŸ“š and πŸ“˜. (1)

The word 'tooth' is etymologically related to French 'dent', German 'Zahn', Irish 'dΓ©ad', Ancient Greek 'odαΉ“n', and Sanskrit 'dΓ‘n'.

These words stem from the same Proto-Indo-European ancestor.

They are remnants of an ancient present participle meaning "biting".

An international team led by archaeologists from Freie UniversitΓ€t Berlin uncovered fortified prehistoric settlements in a remote region of Siberia. The results of their research reveal that hunter–gatherers constructed complex defense structures around their settlements 8,000 years ago.

This is really quite something... #Antarctic sea ice extent is back to a record low for the current date. This is actually below 2016, which was previously a massive outlier in November and December.

"The present study has highlighted the gene-culture co-migration with the demographic movements that occurred during the past two millennia in Central and East Asia. Additionally, this work contributes to a better understanding of the distribution of immunogenic erythrocyte polymorphisms with a view to improve transfusion safety."

"Scientists have developed tiny robots made of human cells that are able to repair damaged neural tissue1. The β€˜anthrobots’ were made using human tracheal cells and might, in future, be used in personalized medicine.

The research β€œpoints the way to a β€˜tissue engineering 2.0’ that synthetically controls a range of developmental processes”, says Alex Hughes, a bioengineer at the University of Pennsylvania in Philadelphia."

"We argue that market power by some corporations and in some sectors – including temporary market power emerging in the aftermath of the pandemic – amplified inflation. It made price increases peak higher and remain more persistent than they would have been in a world with less market power. To be clear: corporate profits were thus not the sole driver of inflation, nor are dominant corporations to blame for the energy shock
caused by Russia’s invasion of Ukraine. But we argue that their market power exacerbated the fallout – and that this is not sufficiently captured in the prevailing macroeconomic debate or in workhorse models."
