In the reductionistic approach that dominates science, we've tried to categorize even our own physiology into sperate systems such as the immune system or the metabolic system. A number of beautiful papers show that things are not so segmented as we might think. A thread.

Colleagues, we need to talk about the damage that endless zooming can do. Every day I see new opportunities to join in this or that online discussion or conference, and each invitation is becoming a burden 1/... #AcademicTwitter #AcademicChatter

For many of us, online conferencing is the main form of contact we have with others. But it's a stripped down form of contact which demands a particular focus and concentration. Colleagues tell me every day that it's more intense, and thus tiring, than IRL interaction 2/...

Communication is attenuated because many of the usual social and symbolic cues that tell us where we are, what our role is, how to interact and respond, are missing. This is especially awful if our interlocutors have their cameras switched off and we're talking into a void 3/...

But we also lose the rest and reset time between events. Instead of those precious minutes on a train to read, or a brisk walk between venues, even just a chat around the coffee pot, we are increasingly leaving one meeting to log on to another 4/...

We do so with no other backdrop than our own four walls, in one chair, glued to a screen, unable to reach out. Our symbolic and social worlds have shrunk. @PostEurope told me it's a form of torture, but that's literally true: a stress position we maintain for days 5/...

The calamoid palms 🌴 have over 500 species spread across the world, but their higher-level relationships were a bit of a mystery. Until now.

Out today in #MolecularPhylogeneticsAndEvolution:

A robust phylogenomic framework for the calamoid palms https://t.co/JiCbSUlheH

First some background info, so that you know what we are talking about:

Calamoid palms look a bit like snakes 🐍 (don't they!?!), because their fruits are covered in overlapping scales. And with their often fierce spines, they are equally fearsome. 😱

2/10

They are classified into 17 genera, 10 subtribes and 3 tribes. They have an amazing variety of growth forms, from stemless to climbing to tree habit. 🌱🌴

But as I said, their relationships have been a bit of a mystery. Here's the varying relationships previous studies found over the last 20 years.

4/10

We tackled this mystery with a phylogenomic approach: we sampled almost a thousand genes (a hundred times more than previous studies!) of 75 species representing all calamoid tribes, subtribes and genera.

The resulting data matrix is pretty massive...

Beyond the scientific and epidemiological reasons to doubt the lab escape theory of pandemic origin, let’s not forget that no US or allied intelligence has emerged with even a whiff of evidence that a lab was the origin by accident or intention.

To believe the lab escape theory you also have to believe the Chinese have mounted a successful, extended campaign to eliminate incriminating evidence and muzzle officials and scientists who knew or might have suspected it came from a lab.

It’s a pretty big secret to hold on to, especially for a sizeable group of people that includes an international network of scientists, other workers, and families -- many of whom are not exactly in the secrecy business.

It’s been 12 months now of intense pressure on Western intelligence services to uncover that secret. Doesn’t have to be a taped confession, slam dunk email, or official document (though that would be handy). It could be indirect evidence or suspicious behavior.

The White House in particular leaned has heavily on US spy agencies to uncover Chinese malfeasance or error. “Trump made clear...his interest in intelligence supporting the theory the virus emerged accidentally from a Wuhan
