Digging Up the Roots of Language

For years, linguists believed it impossible to trace the genealogy of human language past about 9,000 years ago, when Indo-European tongues split somewhere near present-day Turkey. A new study out of the University of Auckland indicates that split is but the first among many, in a tree whose roots extend all the way to southwestern Africa, some 70,000 years ago. . . .



The Nurture of Gretchen Carlson: A Guest Post by Bryan Caplan

Bryan Caplan, a professor of economics at George Mason University and a blogger for EconLog, has written a new book called “Selfish Reasons to Have More Kids: Why Being a Great Parent Is Less Work and More Fun Than You Think.” And he’s been guest-blogging for us about parenting. I had a chance to interview Caplan yesterday for an upcoming Freakonomics Radio show called “An Economist’s Guide to Parenting.” He had a great deal to say on the topic, all of it interesting and much of it provocative. I think you will enjoy it as much as I did.

"Conspicuous Conservation" and the Prius Effect

This month, Toyota sold its one millionth Prius hybrid in the U.S. In 10 years, this strange-looking vehicle with the revolutionary engine has claimed a spot among the best-selling cars. Pretty impressive. But are all those Prius owners thinking mainly about better mileage and a smaller carbon footprint, or is there another incentive at work?

Hungry, Hungry Judges

If you’re going to court, you better hope that judge had breakfast. Or just a break. A new study looked into psychological effects in the courtroom from the supply side: the judges. Researchers evaluated results from more than 1,000 rulings made by 8 Israeli judges and found that favorable rulings peaked at the beginning of the day, then again after lunch or a food break.



The U.K.'s 'Under-Aged' Socially Networked Children

According to a new study by the London School of Economics, one in every three children in the U.K. between 9 and 12 has his/her own Facebook page, despite Facebook’s minimum age requirement of 13. Among 13-16 year-olds, that number shoots to 43 percent. Researchers noted that European children are taking undue risks online.



A Biblical Post

Photo: David Campbell 2 Kings VII discusses an incident in which the people of Israel are besieged and food prices are skyrocketing.

The officer is shortly trampled to death after the populace goes . . .

Last week, a severe outbreak of tornadoes tore across much of the southeast U.S., killing at least 43 people. Despite the destruction, meteorologists are working on a handful of advancements that should greatly improve our ability to predict tornadoes.



Looking Back at the Gulf Horizon Spill

It’s been almost a year since the Deepwater Horizon spill in the Gulf of Mexico, and more data is available on the magnitude of the spill. In a recent article, The New York Times describes the spill’s size as “some 4.9 million barrels of oil.” That led me to two numerical musings.
First, I wanted to make the number meaningful by comparing it to another large, famous spill: the Exxon Valdez. Its size is imprinted in my memory as 11 million gallons, which is about 250,000 barrels. So the Deepwater spill was about 20 times larger than the Valdez. In retrospect, that makes sense. The Deepwater well reached into a geologic formation. Whereas the Valdez was merely what one could take from another formation and stuff even into a big ship.

I’m back to inviting readers to submit quotations whose origins they want me to try to trace, using my book, The Yale Book of Quotations, and my more recent research.



The New and Improved Coup d'etat

Sometime around 1991, the standard coup d’etat morphed into something else entirely, according to a new paper by Nikolay Marinov and Hein Goemans: “[W]hereas the vast majority of successful coups before 1991 installed the leader durably in power, after that the picture reverses, with the majority of coups leading to competitive elections.”



Ten Things You Need to Do if You Were Hired Today

The woman right next to me was alive one second, then a taxi came up on the sidewalk of 42nd Street between 6th and 7th Avenue, hit her and veered off, and now the woman was dead. This happened on the first or second day of my job at HBO. I tried to call 911 on the payphone (there were still payphones in August, 1994), and then I had to go. The woman was dead.



Dear Globalization: Thanks For The Edamame

We took our visiting 12-year-old granddaughter out to dinner last night, and she insisted on ordering edamame, which I too love.  I discovered it at age 60 and would never have seen it in the U.S. at age 12 in 1955.  Earlier in the day, I had bought a cherimoya at the local grocery store.
