Kind of a Global North problem.
Map showing countries that walked out during Netanyahu's speech. Most of South America walked out, as did a large part of Africa, most of the Middle East, Pakistan, Malaysia and Indonesia and a few more. Of the "Global North" countries only Spain and Ireland walked out.

A massacre in El Fasher, #Darfur, #Sudan ... 84 killed during prayers at a mosque, according to Mashad Observatory for Human Rights (www.facebook.com/photo?fbid=1...) and Sudan War Monitor (sudanwarmonitor.com/p/worshipper...) #KeepEyesOnSudan
Mashad Human Rights Observatory strongly condemns, with the heaviest heart and deepest sorrow, the horrific crime perpetrated by the Rapid Support Forces through their terrorist shelling of the mosque in the city of Al-Fashir during prayer, which resulted in the killing of more than 84 civilians, including 11 children and the Director of Mashad Organization in the state, and the injury of dozens with serious wounds. This brutal attack constitutes a blatant violation of all international laws and norms, foremost among them international humanitarian law and international human rights law, and amounts to a fully-fledged war crime under the Geneva Conventions and the Rome Statute of the International Criminal Court.

The recurrence of these crimes against innocent civilians and the targeting of places of worship and public facilities clearly demonstrates the systematic approach adopted by the Rapid Support Forces in killing Sudanese people and destroying their means of survival, under the watch of the international community, amid a suspicious silence and negligence that rise to the level of indirect complicity and encourage the continued commission of further atrocities.

Mashad Observatory affirms that this terrorist crime constitutes a stain on the conscience of humanity and irrefutable evidence of the support extended by certain international and regional powers to these criminal forces in pursuit of their own interests at the expense of innocent blood. Silence over such grave crimes undermines the values of international justice and erodes what remains of trust in the global system to protect human rights and safeguard human dignity.

We issue an urgent appeal to the peoples of the world of conscience and to what remains of honorable international and regional institutions to condemn this terrorist act ... [see the rest on their the Mashad Observatory Facebook]

#ABPHM25 was once again an amazing opportunity for learning, networking and taking the pulse of the public-health oriented microbial bioinformatics field. Here's a part of the attendees, self-selected from participants on the µbioinfo Slack. Best wishes to everyone as we head home and #FreePalestine

I feel a real need for things-that-don't-suck this morning so here's a picture of the baobab tree I bought in The Gambia recently with its new leaf and the vanilla pod from Madagascar I was given at the food festival yesterday. Sembrando ideales!

TFW you're just calmly listening to TWIP and you discover that Thomas Winterbottom "discovered" what is known as Winterbottom's sign (a telltale sign of sleeping sickness) by observing the behaviour of *slave traders* in what's now Sierra Leone #colonialmedicine

As I get ready to put the bioinformatician boots on again (a week later than planned), I had a really good time taking a variety of folks on their first ever rockpooling expedition. I'm leaving out the pictures of peeps, but here's an atmospheric shot.

One of the TAC innovations was the "HIV Positive" t-shirt, which flipped the script of HIV+ from a shameful, to-be-hidden diagnosis to a statement about struggle & solidarity (eventually Mandela himself wore one). Use all tools to fight! (the shirt drew on a long history of use of t-shirts & design)

(mostly) colonial powers (Netherlands, UK, France & Thailand) working to control the trade. Access to rubber (for war & industry) was also a reason the Japanese invaded the DEI & my father spent part of his childhood in an internment camp. The picture attached is from Tjideng camp, created from

Thinking about #ColonialHistory... my father was born in Tosariweg, Batavia (now Jakarta), in a house next door to the one pictured. His father was an agricultural engineer, working to control the rubber trade. Rubber was big business & the "Dutch East Indies" a major part of this, with a cartel of

Oh look... it's someone polluting my timeline with "lab leak" / "gain of function" nonsense. I'm blocking them and would advise others to do similar. Life's not long enough to waste time with people promoting these discredited theories...

📖 #BookSky: "What can she know?" Lorraine Code's 1991 book asks "is the sex of the knower epistemologically significant?" & answers the q in a way that draws on the importance of "second person knowledge" truth-building as a social species. It grounded me in the fundamental importance of others

ZT herself linked this to a "vaccine trial gone wrong" and now you link it to a lab leak. Considered the evidence there? Anyway, here's more of the ZT stepping way outside her area of expertise & frankly making an astounding claim.

This is an example of ZT's recent tweeting. How is this "good faith" communication? She mixes up a vaccine trial with commentary about lab research that talks to "lab leaker" (and, notably, TESCREAL) talking points. This isn't just "off-script".

Aha! That probably explains why those who saw #aurora in South Africa saw red (e.g. africanews.space/southern-afr... - unfortunately can't link to the SANSA page because that seems to be down) - they were catching the "top" of the aurora (the rest being below the horizon) perhaps?

There's something missing on BlueSky: no discussion of #TB, #tuberculosis or the King of Pathogens, Mycobacterium tuberculosis. (This is at a time when other social media is abuzz with talk of #TB & nutrition, campaigns on bedaquiline & GeneXpert, etc) Hope to see this change soon

With the assistance of my second-cousin-in-law I'm tracing the ins and outs of my father's family. Turns out that my great⁶ grandfather got into some legal trouble in the 1720s... I've found what I think is the relevant document from 1724 but struggle to decode the goose-quill scratchings. Amazing!
