I've blogged old radium-based health product ads before, but this one is a bit of a cake-stealer: the Revigator, sold in the 1920s, was a uranium-infused crock that you filled with drinking water so that it could be made radioactive prior to imbibing.
The glazed ceramic jar had a porous lining that incorporated uranium ore. Water inside the jar would absorb the radon released by decay of the radium in the ore. Depending on the type of water, the resulting radon concentrations would range from a few hundred to a few hundred thousand picocuries per liter.

One of the major contributors to greenhouse gases is the methane that cows belch up as they break down cellulose, but five years ago, research from Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) found that adding small amounts of a pink seaweed called Asparagopsis to cows' diets eliminated the gut microbes responsible for methane […]
On Slate Star Codex (previously), Scott Alexander breaks down Invisible Designers: Brain Evolution Through the Lens of Parasite Manipulation, Marco Del Giudice's Quarterly Review of Biology paper that examines the measures that parasites take to influence their hosts' behaviors, and the countermeasures that hosts evolve to combat them.
Are we done with capsule coffee makers yet? Sure, they’re easy. But they are not so easy on the environment, and it’s debatable whether they actually make a better cup. Luckily, there’s never been a better time to switch back to the good old reliable drip method – especially when drip coffeemakers have quietly been […]
If there’s one thing that stayed consistent through the last decade or so of tech industry turmoil, it’s the love affair between techies and Linux. There’s just a ton you can do with the OS, and its open-source format means you can customize your rig from the ground up. Apparently not content with that level […]
Accidents happen. And when they do, you’re going to want a dash cam for a second pair of eyes. At the minimum, a decent dash cam can save you vast sums of time and money in case of an accident. But a really good dash cam can do a whole lot more. Here are six […]
