Scientists discover spiders are eating snakes all over the world
“They can outfight snakes 10 to 30 times their size,” says the University of Basel in Switzerland.
According to a new meta-analysis study, perhaps snakes should be fearful of spiders. It seems arachnids like to chow down on the reptiles, all over the world.
The study, published in The Journal of Arachnology, has the straightforward title Spiders (Arachnida: Araneae) Feeding on Snakes (Reptilia: Squamata). The researchers looked at 319 reports of spiders feeding on snakes from every continent except Antarctica. Most of the events occurred in the US and Australia.
The data showed that spiders representing 11 different families have been observed eating snakes. “That so many different groups of spiders sometimes eat snakes is a completely novel finding,” lead author and arachnologist Martin Nyffeler said in a Monday news release from Switzerland’s University of Basel. Guess we can add the discovery to our Surprising Insect Dining Habits file, alongside praying mantises eating hummingbird brains.

Abolishing tenure is the least of my proposals
In my latest Bloomberg column I attempt to design an ideal university from scratch. The point is not that all schools should be this way, rather this is the experiment I would like to see at the margin:
I would start with what I expect students to know. They should be able to write very well, have a basic understanding of economics and public policy, and a decent working knowledge of statistical reasoning. I would give a degree to students who demonstrated “B-grade” competence in all of these areas; what now goes for passing C-minus work wouldn’t cut it.
Most important, the people who write and grade the students’ tests would not be their instructors. So students would have to acquire a genuine general knowledge base, not just memorize what is supposed to be on the exam.
Next, each student would have the equivalent of a GitHub certification page. If you learned three programming languages, for example, or won a prize in a science fair, that would go on your page as a credential. But it would not count as a credit toward graduation. Some students could finish their degrees in a year or two even if their pages were not adorned with many accomplishments, while others might fill their pages but get no degree.
My imaginary school would not have many assistant deans, student affairs staff or sports teams. The focus would be on paying more money to the better instructors.
And:
Instructors would not have tenure, but would have to compete for students — by offering them classes and services that would help them graduate and improve the quality of their certification pages. Teachers would be compensated on the basis of how many students they could attract, in a manner suggested long ago by Adam Smith, who himself lived under such a system in 18th-century Scotland.
The very best instructors could earn $300,000 to $400,000 a year…
The school would hire online instructors too, many of them from poorer countries and working at lower wages. So you might take French from a tutor in Senegal, or have a high school teacher from Tamil Nadu read your essays and offer writing tips. I am a big believer in face-to-face instruction, but in my school it would have to compete with online instruction. For this reason, I think my school would have a much more diverse faculty and instructional base than any other institution of higher education. None of the instructors would be required to have any undergraduate or advanced degrees.
The goal is to introduce competition across as many different margins as possible. There would be an “all on-line” option as well, offered to anyone in the world, though of course the on-line degree might be worth less as judged in the market place.
One issue I did not have time to get into is how the school would “shadow price” its different services to students. Access to different services has to be priced somehow, so should the school hand out total vouchers to each student for use within the school? Should the on-line and also face-to-face classes be priced at marginal cost (plus mark-up)? Or do positive externalities from class cohesion mean that the face-to-face classes should be priced at some additional discount? To what extent should factors other than this shadow price system be used to allocate access to classes?
Wyoming fact of the day
Wyoming—the first US state to grant a charter to a crypto bank—has approved legal status for a decentralized autonomous organization (DAO), the American CryptoFed DAO, according to an announcement on Sunday. The organization, which has a mission to introduce a new monetary system, now becomes the first legally recognized DAO in the U.S.
It comes after Wyoming lawmakers voted in March to pass a bill allowing DAOs to be officially registered in the state. The law affords these entities—which are governed by smart contracts and dispense with the hierarchical control structure seen in traditional companies—the same rights as a limited liability company. The bill came into effect on July 1, 2021.
Just think — limited liability for “a company managed by nobody”! And:
The DAO law also solidifies Wyoming’s reputation as the most crypto-friendly U.S. state. Last year, it was the first in the US to issue a state charter for crypto banks and has already licensed two: Kraken and Avanti.

A new study of crypto ownership
Employing representative data from the U.S. Survey of Consumer Payment Choice, we disprove the hypothesis that cryptocurrency investors are motivated by distrust in fiat currencies or regulated finance. Compared with the general population, investors show no differences in their level of security concerns with either cash or commercial banking services. We find that cryptocurrency investors tend to be educated, young and digital natives. In recent years, a gap in ownership of cryptocurrencies across genders has emerged. We examine how investor characteristics vary across cryptocurrencies and show that owners of cryptocurrencies increasingly tend to hold their investment for longer periods.
And:
Moving from a lower category of education to a higher one increases the probability, on average, of recognising at least one cryptocurrency by around 8.7 to 11.1 percentage points…Being a man in the US increases, on average, the probability of knowing
about at least one cryptocurrency by between 9.6 and 12.1 percentage points.
That is from a recent paper by Raphael Auer and David Tercero-Lucas, via Shaffin Shariff. Data are from 2019.
Facts and uncertainties about ear wax
Our attitude to ear wax is in some ways surprising. A review of impacted ear wax estimates that 2.3 million people a year in the United Kingdom suffer problems with wax needing treatment, with some 4 million ears being syringed annually.2 This makes it possibly the the most common therapeutic procedure carried out on any part of the body. Symptoms of excessive wax or impaction, especially in the elderly, include not only hearing loss but tinnitus, dizziness, infections, social withdrawal, poor work function and mild paranoia. Other problems include general disorientation and loss of an aural sense of direction. With unilateral wax, sounds can appear to be coming from the wrong side, leading to accidents as a driver or especially as a pedestrian. Inappropriate self-treatment (or even treatment by health professionals) can cause perforated eardrums and in very rare cases cochlear damage, leading to nystagmus and sensorineural deafness. In spite of this catalogue of harms, the clinical profile and management of excessive wax are poorly understood. The evidence base is poor and inconsistent, leading to few strong recommendations, even relating to the most commonly used treatments.
Low esteem for ear wax is surprising in other ways too. As a substance, it is unique in the human and mammalian body. This is due to its position in our sole anatomical cul-de-sac. Everywhere else on our body surface, dead and redundant skin cells fall off or are scrubbed away when we wash. In the ear canal – which points forwards and downwards and might otherwise turn into a dermatological garbage dump – ear wax binds these together, along with other assorted detritus that may have entered from the world outside. It is then moved up to the exit by jaw movements and as a result of the skin of the canal slowly moving outwards like an escalator. Wax also prevents multiplication of micro-organisms and infection. It is as essential as sweat and tears, although perhaps not quite as vital as blood. Wax is also fascinating in its own right.
Imagine an ear wax post that is not solely about Q-tips! (Have you ever wondered why they have to be so dangerous? Can’t you just put them in a little way? Or is there some indivisibility here? I have never understood the anguished warnings here. If you are not using Q-tips at all, you only have to put them in a little way to pull out a lot of earwax, right? Solve for the equilibrium!)
Here is more by John Launer, about ear wax throughout, via Michelle Dawson.

*The Volga: A History of Russia’s Greatest River*
The author is Janet M. Hartley from LSE, here is one excerpt:
…the religious composition on the Volga is complex. Finno-Ugric settlers originally followed shamanistic beliefs, although many converted, at least nominally, to Orthodoxy after they became subjects of the Russian Empire. The ruler and the elite in Khazaria probably converted to Judaism sometime in the early ninth century. Kalmyks in the south and south-east of the Volga were Buddhists (the only Buddhists in Europe). The Bolgar state, the Golden Horse and the khanates of Kazan and Astrakhan were, or became, Muslim. the Russian and Soviet states were conscious of the potential threat of Islam in the Volga region from the time of the conquest of Kazan in 1552. The history of the Volga is, in part, the history of (often forced) conversion to Orthodoxy by the Russian government and the reaction to this of the local inhabitants. In many cases, the conversion process was incomplete or, in the case of Islam, could be reversed. The remoteness of much of the Volga countryside attracted Old Believers — that is, schismatics from the Russian Orthodox Church who did not accept the changes in liturgy and practice in the middle of the seventeenth century.

Let’s all have a revisionist Fourth of July
That is the theme of my latest Bloomberg column, here is one excerpt:
Revisionist history serves many useful purposes, and for the most part it should be encouraged — even though many particular revisionist claims turn out to be wrong. The natural human state of affairs is a kind of complacency and acceptance of the status quo. If historians sometimes write a bit too sharply or speculatively to capture the audience’s attention, it is a price worth paying. At any rate, the audience tends not to take them literally or to pay close attention to their more detailed claims.
And:
The problem is that the revisionism isn’t diverse enough. A few issues — most of all those raised by Critical Race Theory — get caught up in the culture wars and are debated above all others. I agree that we should devote more time and attention to America’s disgraceful history of slavery and race relations, and I have incorporated that into my own teaching.
Still, other matters are being neglected. The longer trajectory of U.S. foreign policy is hardly debated, or what that history should mean for current decisions. There is plenty of carping about “the deep state,” but actual history has fallen down a memory hole, including the history of U.S. intelligence agencies.
It gets worse yet. According to one recent survey, 63% of the American public is not aware that six million Jews were killed in the Holocaust. Ten percent had not heard of the Holocaust at all. Or consider the treatment of Native Americans, which was terrible and produced few heroes. Yet American soul-searching on this history seems to be minimal.
America needs revisionism, more of it please, and on timely and controversial topics. But it also needs less politicized and more intellectually diverse interpretations of its history. On this Fourth of July, what America needs is not the promotion of some particular claim of historical hypocrisy, but the elevation of the historical itself.
Recommended, and have a happy Fourth!
