the fish the advice was written for
Eat at least 8 ounces of high-omega-3 seafood a week, US guidelines say. They mean salmon.
The fish that advice was written for was measured: 3,000 farmed salmon. Its omega-3s fell from 2.74 grams per 100 g to 1.36. Half. The study's own title: Impact of sustainable feeds on omega-3 long-chain fatty acid levels in farmed Atlantic salmon, 2006-2015.
Salmon get omega-3s from fish oil, a finite wild pool. Mills swapped in soy and canola; in Norway fish oil fell from 24% of feed (1990) to 11% (2013).
The paper's math: the daily dose needed twice the salmon in 2015 vs 2006.
Salmon is not the villain: one 2015 portion still met the daily dose.
This month USDA-led research reportedly found them down considerably. The study is not public and the agency will not discuss it.
The swap was called sustainable: it saved wild fish by spending the fish's reason to exist.
Eat the salmon if you like it, but the case for it was built on a fish that stopped existing in 2015, and the office that keeps the number current wrote the advice. They measured the fish. They are not telling you by how much.

the missing color
A tree shrew wears tiny glasses. A blur signal makes one eye grow too long, the same signal as childhood myopia. Add one color, indigo at 419-446 nanometers, and it doesn't. Suppressed completely.
The strange part: the eye has a sensor that isn't for seeing, OPN5. Violet switched it on in mice, but human lenses block almost everything below 400 nanometers, so the color must sit just above. Indigo is first. Sunlight has it; indoor light barely does.
The bill: 2.8 billion myopic now, 4.8 billion by 2050; children 24.3% in 1990, 35.8% in 2023, 740 million by 2050.
Outdoor time works, the authors admit, but it isn't coming back. Change the light; a day care trial is next.
Plain words: the scientist who named it sells it. Rafael Grytz founded Electric Indigo, selling light-emitting eyewear for kids. Patents pending with Richard Lang; the university owns a stake. All disclosed; disclosed isn't wrong. The only human trial, 2017 violet-transmitting glasses, was small and not significant.
We took a color out of the light our eyes evolved under. The largest uncontrolled experiment of our era wasn't a drug; it was a lamp. The science looks real. The sales pitch started before the trial.

the count ends in 2019
In 1970 the United States passed a clean air law. By 2020 its six named pollutants were down 78 percent.
The part nobody counts: what an unborn baby breathes.
64.5 million birth records, 2,842 counties, 2003-2019. Prenatal fine-particle exposure fell 34 percent; without fire, 37. Wildfire's share of what a fetus breathed more than doubled, 3.7 to 8.2 percent. The gain the fires ate: 0.22 micrograms.
Bad days sharpen it. The daily limit from 2006 was 35 micrograms per cubic meter. Non-fire days over it fell 85 percent; fire days never fell. By 2019 wildfire caused 65 of every 100 bad days left for the unborn.
It falls hardest on low-income counties and American Indian and Alaska Native infants; maternity-shortage counties carried nearly double the wildfire share of well-served ones.
The record ends: 2019, before California's record years and the 2023 Canadian smoke. Carry it to 2026 and the share rises, the authors say. Babies born since have breathed outside the official count. The smoke kept coming. The count stopped.
0.22 micrograms sounds like nothing. It is the size of a promise that held fifty years and is leaking. The record ends exactly where the proof would arrive.
