These girls got their hair did.
Yesterday, Cory posted a vintage ad for boys' hats and accessories, which included a small selection of ties made from something called "Aralac". I didn't think much of it, until I noticed J. Brad Hicks' comment pointing out that Aralac was a synthetic wool made from cheese. Which was not a joke.
Seriously. It'll make more sense once you understand how the stuff was actually made.
Think about it this way: Wool (the actual kind, that comes from sheep) is a protein. So is casein, which is found in milk. Making Aralac is basically about getting the protein casein to behave like the protein wool. In 1937, Time magazine described how the process worked:
Having practically the same chemical composition as wool, it is made by mixing acid with skim milk. This extracts the casein, which looks like pot cheese. Evaporated to crystals, it is pulverized and dissolved into a molasses consistency, then forced through spinnerets like macaroni, passed through a hardening chemical bath, cut into fibres of any desired length. From 100 pounds of skim milk come 3.7 pounds of casein which converts to the same weight of lanital. [Aralac was also called Lanital.]

Editorial note — Cow Week is a tongue-in-cheek look at risk analysis and why we fear the things we fear. It is inspired by the Discovery Channel's Shark Week, the popularity of which is largely driven by the public's fascination with and fear of sharks. Turns out, cows kill more people every year than sharks do. Each day, I will post about a cow-related death, and add to it some information about the bigger picture.
Some cow-related deaths are accidental, or at least understandable. When humans and animals live and work in close proximity, it's not surprising that humans sometimes do things that startle or scare the animals. And when 500-pound animals are scared, bad things can happen.
Other times, though, it really seems like the cows are out to get us. Take this story, related in the July 31st issue of The Times of India. Bhoop Narayan Prajapati, a 65-year-old resident of Deori Township in the Sagar district of Madhya Pradesh, was gored by a bull and later died of his wounds. But, the death turns out to be the culmination of a months-long feud between Prajapati and the bull, centered around Prajapati's attempts to get the bull to stop sitting in front of the door to his house.
Prajapati threw a cup of hot water at the bull one morning. The next day, the bull came back and gored him. But that wasn't quite enough.
Much to people's surprise, the bull reached the hospital following Prajapati. Deepak Chourasia, a town-dweller, said that when the mortal remains of the old man were being consigned to flames the bull again sprang a surprise by arriving at the crematorium.
There is a minor history between Prajapati and the bull. Six month ago, the bull had attacked the old man after he hit the animal with a stick. Prajapati was at that time admitted to a hospital where he stayed for more than a month due to leg injury, Deori police station inspector R P Sharma told TOI.
Yesterday, I told you about how cows kill more people every year than sharks, even though sharks are (by far) the more-feared species. Today, let's look at this from the shark's perspective. Turns out, sharks are actually threatened ... by us. Yes, they have pointy teeth, but we have harpoons and nets.
In a 2010 article for Our Amazing Planet, Charles Q. Choi reported that as many as 1/3 of all shark and ray species in the world are at risk of dying out. Most of the deaths are accidental. Sharks can simply end up caught in nets meant for other animals. But there's also a thriving trade in shark fins and plenty of money to be made in allowing fishermen to hunt sharks for sport. Overall, humans intentionally kill upwards of 73 million sharks a year, according to a 2009 New York Times editorial.

In 2008, some scientists proposed that cows can sense magnetism and actually line up in fields along Earth's magnetic lines. It's the sort of paper that everybody in the media wants to talk about for, roughly, two weeks ... and then never mention again.
But that's not how science works. One research paper does not an unquestionable fact make. Luckily Discover's Discoblog has been kind enough to update us on the current state of magnetic cow research. Shorter version: This issue is far from settled, with a second research team attempting to poke holes in the original study. Nevertheless, outside researchers say, the original findings still look strong. There is evidence that herds of cows stand along magnetic lines, and fail to stand along those lines in the presence of magnetic-field distorting high-voltage power lines. Whether this is absolutely the case and, if so, why, remains a bit of a mystery. Needs moar research.
... an analysis of Google Earth images by another team finds no such lining up. In a back-and-forth over the last year in scientific journals, the first team reanalyzed the second’s data and said that half of the images were useless, since they were near high-voltage power lines or contained hay bales or sheep instead of cows. Plus, the first team points out that the second team looked at single cows within herds instead of herds as a whole, and it’s pretty clear at this point that animals in herds and flocks aren’t operating as independent entities. The second team retorts that their images were too okay to use, and the first team may have been looking at the wrong pictures.
