Excellent talk by Simon Sharpe @INETOxford just now, pointing out how the #climate crisis challenges economic #orthodoxy in several ways. Spoiler šŸ”„"Economics as a discipline has forgotten what the scientific method is" (@camjhep pointing to #heterodox ideas in defense)šŸ§µ
šŸ’”The premise: To meet our #climate goals, we need to reduce emissions globally by about 8% per year by 2030, as compared to the 1,5% p.a. achieved so far - hence the title of his book #FiveTimesFaster
1āƒ£ An #economy going through the rapid and far-reaching systems #transition this requires (acc. to @IPCC_CH) cannot be analysed in terms of #equilibrium, a sitation in which "nobody has any immediate reason to change their actions" according to the Oxford Dictionary of Economics. Image

First, kudos to the Chinese authors doing this work & a shoutout to @edwardcholmes also involved

I already flagged this Wang et al. preprint yesterday but it is worth explaining its significance to both the #origins discussion and the related pandemic #prevention discussion

AšŸ§µ
First: Origins

One thing that goes often down in all the noise surrounding #lableak is the fact that SARS-CoV-2, and actually all CoVs, possess #mosaic genomes.

This is because CoVs evolve not only through mutation but also through exchanging genetic elements with other CoVs
2/
This exchange is called '#recombination'.

One can imagine CoV genomes like colorful Lego brick walls, and recombination as taking one brick from a different virus and putting it in the wall of another; changing the color while keeping roughly the function.

The Mitochondrial #Eve is the most recent woman from whom all living humans descend. šŸ§µšŸ”½ Painting of Eve, the first ...
The mitochondrial haplogroup mt-MRCA was split at around 155,000 years ago, which is later than the speciation of Homo sapiens.
The Y-chromosomal #Adam is the male analog to the "Mitochondrial Eve", and is the individual from whom all living humans are patrilineally descended.

The age of the Y-MRCA is subject to substantial uncertainty.

Continuing excellent coverage of the #COVID19 pandemicā€”and the science of epidemiologyā€”by @FoodieScience and @NPRinskeep.

npr.org/sections/goatsā€¦
's comments to @FoodieScience were based on our research estimating the durability of immunity to COVID-19 using comparative phylogenetics.

In case anyone is keeping score, we applied comparative evolutionary approaches (long before reinfection was common) to predict the durability of immunity, and our predictions were SPOT ON.

A new job, a #pig, a pregnancy, a move, a pandemic, 5(6) rev and many #pampers later, Iā€™m delighted to share my co-first authorship with @KellerValsecchi in the @AsifaAkhtar1 lab today in @nature. Thread below for summary nature.com/articles/s4158ā€¦
In this crazy journey we reconstituted the minimal #Drosophila requirements to achieve #Xchromosome targeting
We systematically asked the hierarchical interdependencies of the known MSL complex members to understand the contribution of #DNAmotif, #interaction_partners and #evolutionary determinants in the process of targeting the single male #Xchromosome for transcriptional upregulation

As promised to @g_m_hodgson & @ingridharvold I got myself a copy of Hodgsonā€™s book e-elgar.com/shop/gbp/is-thā€¦. Itā€™s hard 2 do justice in a thread to the many arguments he makes, but Iā€™ll try to engage. 1/
Among other things, a) Hodgson correctly points out that lack of raison dā€™etre 4 hetecon may be responsible 4 its marginalization. I also agree that b) agreement on a ā€œcoreā€ among hetecons would be desirable. He also notes c) general neglect of micro (Iā€™ll return 2 this). 2/
Reviewing various attempts at self-definition of heterodoxy, Hodgson looks at the late Fred Leeā€™s ā€œpoliticalā€ project of gathering anti-capitalist economists under the heterodox umbrella as prone to failure; & Tony Lawsonā€™s dichotomy b/w ā€œopenā€ and ā€œclosedā€ systems... 3/

THIS šŸ‘‰ #Mitochondria play a role in helping white blood cells target human #pathogensā˜ļøBelow, mitochondria-derived vesicles delivered #antimicrobial reactive oxygen species to control phagosome-localized S. aureus (a #bacterial infection)
So letā€™s add #mitochondria to the growing list of human organelles/proteins/pathways recently shown to have #antimicrobial activity šŸ‘‰ Other compounds already on that list include #amyloid beta, alpha-syn, PrP, #HMOs etcā˜ļøMore context here: microbeminded.com/2018/12/30/myfā€¦
Also #mitochondria are derived from #bacterial ancestors, and can become infected by a range of viral/bacterial #pathogens šŸ‘‰ Suggests mitochondriaā€™s antimicrobial activities may be defense mechanisms that stem from their #evolutionary history as a free-living organisms
