Radiant Energy Group recently published a massive international survey of opinions on nuclear energy.

It's full of some things you might already know, but it also contains some surprisesđź§µ

For example, did you know French and German nuclear support isn't that different? Image
Nuclear does have less support than other green technologies, but in most places, it still receives net support. Image
This apparently low level of support looks higher when survey participants are asked about their ranked supported for different energy sources. Image
This support increases further if you subset to people who are techno-optimists or tech-neutral when it comes to fighting against climate change. Image
Unfortunately, most people aren't aware about nuclear is exceptionally clean. Even larger numbers think nuclear waste is a major point of worry.

The Simpsons has done incredible damage to the reputation of our best energy source. Image
Onto the demographics!

In some countries, the old are the most supportive of nuclear. In others, it's the young. Image
If you've seen other surveys on the demographics of nuclear support this one won't surprise you: men are universally more supportive of nuclear. Image
If you've seen other surveys on the relationship between science knowledge and nuclear support, this won't surprise you either: the most knowledgeable are (almost) universally the most supportive of nuclear. Image
Despite being the current best option for providing reliable, low-cost, and clean energy, being concerned about the climate generally predicts less support for nuclear.

When climate concern is represented by nonprofit membership, there's a similar result.Image
Image
Despite the nuclear industry being aligned with numerous (typically) left-wing goals from protecting the environment to supporting labor unionization and high employee safety standards, it's the economically right wing that's more supportive of nuclear. Image
There's more in the report, but I'll end this thread on a happy note: globally, there's more support for additional nuclear builds than for additional nuclear shutdowns. Image

What happens when scholars get canceled?

They end up publishing fewer papers and they receive fewer citations.

In other words, scientific productivity fallsđź§µ Image
Tons of scholars have been cancelled in recent years.

That is, they've received professional backlash for expressing views that people deem "controversial, unpopular, or misaligned with prevailing norms." Image
Cancellations happen outside of academia, but it's very bad in it.

Large portions of the academy dislike the freedom of speech. Many of those free speech opponents have high agency and the clout to cause material harm to people they dislike = particularly bad cancel culture. Image

You must pick one:

Double the productivity of the bottom 20% or double the productivity of the top 1%:
Double the productivity of the bottom 40% or double the productivity of the top 1%:
Double the productivity of the bottom 60% or double the productivity of the top 1%:

Phenotyping is the vast, minimally-explored frontier in genome-wide association studies.

Important threadđź§µ

Briefly, phenotyping is how you measure people's traits. Measure poorly, get bad results; measure well, get good results.

Example? Janky knees. Image
The janky knee example refers to osteoarthritis, the most common form of arthritis, which occurs when the cartilage between bones is worn down, so bones start rubbing against each other.

This ends up being very painful. Image
Everyone with this condition isn't necessarily diagnosed with it.

This is especially true for men, who tend to just ignore this (and many other conditions) more often than women do.

This is, in a word, annoying, because it means that if you study it, sampling is likely biased. Image

ADHD is a condition that's suffered from diagnostic drift: it's been defined more leniently over time, so more people are getting diagnosed.

One way to see this is to look at the benefits of taking ADHD medication. As prescription rates increased, the benefits have declined. Image
Another way to understand diagnostic drift is to look at the factors that promote it.

For example, school accountability laws lead to more diagnoses and, as a result, more psychoactive drug prescriptions.

Schools are pressured by law into making this happen. Image
An even more direct way to understand ADHD's diagnostic drift is to look at what types of diagnoses happen over time.

The increase has been more about non-severe ADHD than clinical ADHD. In other words, people with less and lesser symptoms are getting diagnosed. Image

I have a story to break.

Columbia is still practicing racially discriminatory admissions in defiance of the Supreme Court's ruling in SFFA v. Harvard.

Newly-leaked data shows they still prefer less-qualified Blacks and Hispanics over more-qualified Asiansđź§µImage
Columbia has made a big show of "complying" with SFFA v. Harvard by noting that their 2024 batch of admits involved slightly less discrimination:

Fewer Black and Hispanic students, more Asian students.

That's what should happen, because Asian students tend to perform better.Image
But, with this leaked admissions data, we can see that race still predicts admissions.

With fair admissions, race should not have a significant effect, and it should not be directionally consistent.

And yet, in this data, it's clear Columbia still discriminates against Asians. Image

Today's big biotech win is that we might be on the verge of a cure for type-1 diabetesđź§µ

Twelve diabetics were injected with stem cell-derived pancreatic islets.

They started producing insulin again.

One year in, 10/12 participants no longer needed to inject insulin. Image
In that chart, you can see the response to a meal.

At baseline, blood sugar levels go dangerously high (right) because participants don't produce insulin at all (proxied by C-peptide levels, left).

But notice the blood sugar and C-peptide levels after treatment: Image
With treatment, the patients kept getting better and better.

Their pancreatic function improved over time, and they became more and more able to handle food, and to do so without the need to inject insulin. Image
