Facts worth repeating: It would be cheaper to pay the ~40,000 or so people employed by the coal industry $1M a year to do nothing than to pay for the health damages (not including climate change) caused by burning coal in the U.S. publichealth.hsc.wvu.edu/news/story?h...

Counting up the costs of coal

Regular readers know that WVU’s Dr. Michael Hendryx has done work on that issue (subscription required), reporting that:

This actually is the root of a lot of my anger and frustration, and yes, grief. I spent years crafting accessible classrooms, advocating for tech, and now every measure I use for access is misused by (mostly able-bodied) students who want to cheat with gAI. And our institutions are no fucking help.

I spent years fighting for tech in the classroom for disability access reasons, arguing that no, accommodation wasn't enough, go for universal design. I've given up. I've lost. AI humping motherfuckers ruined it. As they ruin everything.

We already do this and companies who want them are happy to pay for PhD student interns. Why do precious and limited NSF funds need to be deployed for this? Most PhD student pursue industry jobs anyways - that has always been true. Use NSF funds to support basic science that industry wont support!

With academic jobs few and far between, the NSF is testing a new approach to graduate education: Giving Ph.D. students industry experience — and dollars — as part of their training. For more, see my latest for @statnews.com. www.statnews.com/2026/07/29/h...

Insurance is a subscription you buy that provides a service when there's a disaster, but if there actually is a disaster, they penalize you and raise your rates, which is like if Netflix put a strike on your account every time you watched a movie

New study shows that — contra widely accepted narratives — there is NO EVIDENCE that professors change their students’ politics and make them more liberal through their teaching

The natural history collections at the University of Texas, holding maybe 5 million specimens, is partly closed down because our buildings are falling apart and UT is doing the bare minimum of life support. We could fix it for 1/5th the price of a vanity purchase of a single dinosaur specimen.

My coauthor Jay Falk's postdoctoral fellowship was terminated by the Trump administration for documenting the hummingbird example in this paper.

Operational biological sex definitions applied to hummingbirds (Bleiweiss 1992; Bleiweiss 1999; Bleiweiss 2001; Diamant et al. 2021; Falk et al. 2022; Falk et al. 2021) where sex is operationally defined by binary plumage phenotypes in the field. Each row depicts a wild individual hummingbird with morphological traits (beak length, plumage coloration), behavioural traits (territoriality) and their unobserved gamete type. This example illustrates how the same individual can be operationally defined as one sex in the field (based on external phenotypes) but classified as a different sex based on their gametes (which cannot be easily observed in the field), highlighting how definitional choices shape scientific reporting of sex.

In our Viewpoint (onlinelibrary.wiley.com/doi/abs/10.1...) we synthesize the gametic definition (outlined by Janicke et al below) and other definitions of sex (e.g., multivariate definition). We contend that is NO consensus on “biological sex” (maybe a consensus isn’t actually necessary…)

There's an OMB rule change that would require political oversight of scientific grants, and could pull any that don't "reflect presidential priorities" Another country has tried this before! It was the USSR and it was called Lysenkoism. By @thsaey.bsky.social www.sciencenews.org/article/omb-...

Here’s what happens when you put politicians in charge of science

Proposed federal rules would rely on political appointees to decide how a lot of U.S. science gets done. History shows the consequences of such actions.

In addition to producing hazardous air pollution and endangering pets and wildlife, fireworks make the 4th of July the most common day for human-started wildfires in the US. The West is a tinderbox - maybe it’s time to consider alternatives without catastrophic consequences.

A graph (frequency distribution) showing number of wildfires caused by lightning (purple) and humans (red) by day of year for the coterminous United States from 1992 to 2012. There is a sharp spike in human-caused fires on July 4 (annotation pointing to this spike added by me).

The NPS will launch 850,000 fireworks in the middle of the night. (Last year, they launched 7,000) That will dump perchlorates and heavy metals into the Potomac River and cause the amount of soot and smoke particles to skyrocket (pardon), at great danger to any creature that breathes.

"The Park Service, in a separate document, similarly said that people should ‘wear an n95 mask when outdoors’ and ‘remain indoors as much as possible during and after the show.’” The guidance is to remain indoors ... during the fireworks. www.washingtonpost.com/climate-envi...

Many animals rely on darkness to rest, feed, move safely and find their way. But artificial light can disturb these natural rhythms, including for migratory species like sea turtles, bats & birds. Watch this video to learn how small changes at home and in our communities can help protect wildlife.

I’ve been thinking a lot about the shifting baseline concept as applied to everyday life. People in their 20’s now have no memory of highly functional systems, products (from blenders to sweaters) that were so well made you could hand them down across generations, or even helpful customer service.

The drop in teen moms is one of the most major factors driving birth rate declines. We've gone from >80 per 1,000 15- to 19-year-olds in 1950 to 50 per 1,000 in 2000 to 12.7 today! This fact needs to be at the forefront of every discussion about birth rates
