The elimination of USAID is a moral atrocity and all involved made a choice to enable, and then lie about, ending the lives of some of the most vulnerable people in the world.

MAE SOT, Thailand (AP) - Mohammed Taher clutched the lifeless body of his 2-year-old son and wept. Ever since his family's food rations stopped arriving at their internment camp in Myanmar in April, the father had watched helplessly as his once-vibrant baby boy weakened, suffering from diarrhea and begging for food.
On May 21, exactly two weeks after Taher's little boy died, U.S. Secretary of State Marco Rubio sat before Congress and declared: "No one has died" because of his government's decision to gut its foreign aid program. Rubio also insisted: "No children are dying on my watch."
That, Taher says, "is a lie."

Teaching a comp math course this year. I used fun examples to hammer this home. The partial sum of the harmonic series up to 10^9 is radically different in 32 vs 64 bit floating point (and of course, the series also converges in any finite floating point).
0.1+0.2=0.3 is not true in floating point.

Of course, I entirely agree the problems are not due to these particular individuals, but things like much of the Russell Group chasing small short-term gains by massively increasing student intake while worsening everything about the ecosystem.

I think anthropomorphizing/personalizing enemies is an old and rather common tactic that fits our psychology innately. Social media doesn't help, but I don't think it's the root cause. We like thinking of "Hitlers" as archetypal villains, without which our problems wouldn't exist.

Even as a white US citizen, my partner and I paid somewhere upwards of £15,000 in immigration fees and related costs to finally get ILR after 10 years in the country, plus many many other hoops to jump through.

The current moment is not a pleasant one...

How do cells navigate up gradients of adhesive proteins?
🤔

Termed "Haptotaxis", this effect is ubiquitous in cell migration, but it's mechanism was poorly understood

We show that passive friction directs cells & explains complex trajectories on gradients

Entirely agreed. In fact, out of an awareness of my own proclivity for laziness, I aim to minimize my own use as much as possible. Below are really the only personal uses I've made of it. I think the uses I've seen are enormously varied by person.

Personally, I use them a tiny bit for certain aspects of coding/sometimes in very specific writing tasks. E.g. I had a paper written but wasn't satisfied with the title. I asked an LLM for 10 alternative titles. I didn't use any of them, but I did use these examples to refine the one I did use.

In my experience, it is very, very idiosyncratic. Some people use them to digest/understand concepts/papers; some people use them to speed up certain coding/tedious technical tasks; some people use them to generate text, but even that varies heavily.

🚨 Excited to introduce FuChi (Fucci chicken), the first avian cell cycle reporter line. Thank you to all those who contributed to putting this paper together. I really think it showcases the power and beauty of the chick embryo as a developmental biology model. 🐥 🥚 🔬 @roslininstitute.bsky.social

"When we design tools that welcome different ways of sensing and thinking, we open new reaction pathways for discovery. Inclusive design doesn’t just widen participation; it expands the very structure-function relationship of science itself."

I wonder how many of the current members agree or disagree with the opening volley of The Dialectical Biologist:

"Scientists act within a social context and from a philosophical perspective that is inherently political. Whether they realize it or not, scientists always choose sides."

This is awful. I'm sorry that this is the timeline we are living in. I hope you are as OK as you can be through all this crap.

You may get a small bit of solace if you sesrch Bluesky for the name of the author of this "article."

Andrew Krause @blindmath.bsky.social · 25d

I am nearsighted but things very close to my face are fine, even if small. But I've been increasingly using some device magnification in the last few years, which is constantly playing badly with awful UI design choices...

I suspect most people are not aware of the diversity in partial-sightedness.

I think we do use synthetic data in the form of outputs from models, either analytically or numerically. But the "quality" of such synthetic data is very different to statistical or AI-generated data, given that the models encode mechanistic hypotheses, which themselves can be tested.
