Is there a website with a vetted, well documented compendium of the anti-science policies that current regime keeps promoting? I can't keep up with the onslaught and need a reference!

Lots of people citing this one: HIV went from a death sentence to…undetectable and people get to live a full and healthy normal life!!!! I mean that’s amazing.

God, this is scary. They are killing science in universities and are pretty open about that. What’s unclear is whether they honestly think this is good for science, or consider it to be acceptable collateral damage of hurting universities, or don’t care as long as it funnels money to corporations.

Tyler Cowen interviews OSTP Director Michael Kratsios. A few points of the conversation worth highlighting:

In my new Expert Voices column @science.org, I argue that the Trump admin's science strategy (as written in Kratsios' Science: A Golden Age)--which gives more authority & funding to the private sector to direct the research enterprise--will harm science, and further erode its public accountability.

Zelenskyy: "When our strikes reached Yandex data centers, it suddenly became little easier to breathe on many social media platforms. Many people noticed it. There was less hate, less division, fewer provocations because there were fewer bots. It's pretty clear where those bots were coming from.

The idea that brains differ between people isn’t new. Neither that the brain’s answer to new experiences is to alter its connections. For two things that sound almost like common sense, there’s still an impressive amount of details to consider. neurofrontiers.blog/your-brain-i... #neuroskyence

I am excited to do a little explainer about the latest publication by Pinar Demirayak ( www.linkedin.com/in/p%C4%B1na... ) in our lab – it suggests that when a brain region is used for attention-demanding tasks, its connection patterns become more idiosyncratic.

The field often examines neural plasticity by comparing the mean of one group to the mean of a control group. That ignores the knowledge that each person’s pattern of brain connections starts out distinct, and an experience is likely to perturb each system slightly differently.

The cortical representation of the PRL (red) shows much more idiosyncratic patterns of connections than a control region (blue). This suggests that the idiosyncratic connections are associated with experience, not development, since these patients developed vision loss in adulthood.

On the other hand, when you look at whole-brain patterns of connections to representations of central vision, they are idiosyncratic, like people’s fingerprints. That is, “if you’ve seen one, you’ve seen only one.” (teal in previous figure have low sim. scores)

In people with central vision loss: We find that whole-brain patterns of connections of the visual cortex don’t change much for people with central vision loss. EXCEPT, in the cortical representations of the part of the retina which people use preferentially for attention-demanding tasks (PRL).

Second: People who have central vision loss often learn to use a 'preferred retinal locus,' which they use as a ‘pseudo fovea’ after central vision loss. This part of vision is used more often for attention-demanding tasks, whereas other parts of peripheral vision are not used for these tasks.

In Central vs. Periph. vision: We find that the whole-brain patterns of connections to the cortical representations of peripheral vision are quite similar person-to-person (in healthy vision controls) – “if you’ve seen one, you’ve seen them all”. (Purple in the figure have high sim. scores)

We examined this in two contexts where different parts of primary visual cortex are used for more (or less) attention-demanding visual tasks. We rely on the amazing retinotopic organization of the visual cortex: central vision is processed by different cortical tissue than peripheral vision.

First context: Typically, people with healthy vision do not use peripheral vision for attention-demanding tasks, preferring to use the central vision of their fovea for such tasks (like reading, recognizing faces, sewing, etc).

I wrote this quickly at a bus stop and didn't realize it would go viral, or else I would have worded it better. But the point is that the media is too credulous about AI killing everyone in 10 years (how?) when climate change is killing people now and will only get worse (we know exactly how).

I resigned from ExxonMobil today. I spent the last three years doing fossil fuel extraction research at both BP and ExxonMobil. Neither company is acting responsibly. They are racing to maximize extraction while the window to act closes, and gambling with our lives. More below.

NIH's Aug 2026 proposal would scrap exact scores and percentiles for three broad bins (top = top 25%). With funding rates at 5% or lower, too much then rides on administrative discretion. It devalues peer review and is a deterrent to engage. Tell NIH before Oct 13. grants.nih.gov/grants/guide...

Every single second, the world hands $6,000 to the fossil fuel industry in subsidies. That’s $5 TRILLION every year. Renewables? Barely a fraction of that. We are literally paying to cook our own planet. When does this madness stop? 🌍💸 #ClimateCrisis #FossilFuels
