It Was Quite a Year — 2024

A lot happened this past year, so here's a refresher — and a few of my favorite science explanations

2024 was a year with so many big stories, it’s hard to remember them all. Here’s a refresher for you as we sail into 2025 — a year where the “broligarchs” will likely make real efforts to take over more aspects of our lives.

It was quite a year, with a few major themes in my view:

  • OA is in trouble, both financially and conceptually, as fraud, funding woes, and favoritism all come to light
  • Funders are getting tired of paying for publishing (Gates), and going back to the well (PLOS) isn’t going to reassure them that they are providing seed funding grants rather than dependency
    • The issues around how/why publishers attached themselves to funders is unsavory enough to occupy a long pause of reflection
  • OA is risky as it enables the “broligarchs” and may feed fascism

There’s already a lot to talk about for 2025. See you there!

Three Favorite Science Insights from 2025

I like surprising science facts, which for me are often explanations for things we take for granted. Here are three from this year that raise questions most people can’t easily answer, even though the questions are pretty pedestrian.

1 — Why does toast takes so long to brown?

Why does toast brown in the last ~20 seconds? Because the water in the bread has to boil off before the maillard reaction can begin.

2 — Why is “clockwise” clockwise?

Because we have a northern hemisphere bias. The sun is always to the south of people north of the equator, so sundial and other timekeeping shadows travel from west to east as the sun travels from east to west (perceptually). We’ve baked this bias into our analog clocks, and from them into language.

3 — Why do we have REM sleep?

This one is more speculative currently, but I like it. Neuroscientist David Eagleman has posed a “defensive activation” hypothesis to explain REM sleep. The logic is that the visual cortex is the brain’s most plastic — i.e., repurposeable — area. When people are visually impaired, it quickly reshapes to compensate with echolocation, superior hearing and tactile senses, and other compensatory activities. Eagleman believes REM sleep is this area’s defense mechanism, preventing other areas from imposing themselves during sleep in a visually capable person. He also claims to have found a correlation with overall brain plasticity across species and their amount of REM sleep. It’s an interesting hypothesis, and he seems to have the receipts.
