Per that definition:

Vacuum tubes (thermionic valves) were the first active electronic components… and by the 1920s, commercial radio broadcasting and telecommunications were becoming widespread and electronic amplifiers were being used in such diverse applications as long-distance telephony and the music recording industry.

So tubes are in! Old lamps are OUT!

Are thermionic diodes allowed or just semiconductor diodes? What about the early crystal diodes (subset of semiconductor). Did the Colossus computer count? Eniac? I guess particular items don’t matter because no individual owns either and I doubt individual built replicas.

What counts as electronics? Guitar speaker with vacuum tubes? Old rotary phone? Lamps so old the electric cords are covered in a hard fabric? If you require solid state / chips and boards rather than things that did the same function without them, you’re excluding the stuff predating that tech.

Research suggests that how a body reacts to a vaccine is altered by the type of microbiome a person has. Studies on the Covid-19 vaccine, for example, suggest it affected the snot’s microbiome, and in turn, the microbiome affected how efficient the vaccine was.

I hope those researchers get paid extra.

The researchers asked 22 adults to shoot themselves up the nose with a syringe full of snot from healthy friends and partners each day for five days. They discovered that symptoms like cough and facial pain, for instance, dropped by almost 40% for up to three months in at least 16 of the patients.

<shudder> There’s no way those 22 could have been paid enough.

The researchers examined about 222,000 menu items from over 2,000 restaurants in Boston, about 1.6 million menu items from roughly 9,000 restaurants in Dubai, and about 3.1 million menu items from about 18,000 restaurants in London. In Boston, about 71 percent of the items were in the USDA database; in Dubai and London, that figure was 42 percent and 56 percent, respectively.

So only 3 cities, with London getting the best dataset.

In Dubai, the researchers did not have the same types of health data available but did observe a strong correlation between rental prices and the nutritional value of neighborhood-level food, suggesting that wealthier residents have better nourishment options.

This makes a case for “correlation does not mean causation”. The title usues the word “link”, but it sounds like poor neighborhoods have cheap restaurants because that’s what customers can afford, which is just another way of saying there’s a correlation between obesity and low incomes.

The research moves toward evaluating the complex mix of food available in any given area, which can be true even of areas with more limited options.

Okay, I appreciate that this is now adding to the data about what food options are available. So even though it sounds like something we already knew, having more proof from a different view is a Good Thing.

Notice that A is obesity prevalence and F is housing prices, which we’d expect to be opposites. There seems to be correlation with A and C. It would be easier to read all of this if F was reversed to ‘lowest housing rates’ or some such.

Edit: above image of the London breakdown is from the cited paper which also breaks down the same factors for Boston and Dubai.
