Why Does Q (Almost) Always Go With a U?

Leaving aside for now the few foreign loanwords (e.g., Qatar, Iraq) where Q shows up without a U, an English Q is the only letter that can't go anywhere without a partner. Why does a Q always need a U? We can blame it on a whole bunch of our alphabetic ancestors.

Because of the French

Before the Norman invasion of 1066, English didn't even have a Q. Words like queen and quick were spelled cwen and cwic. Not only did the Normans inject a whole bunch of French vocabulary into English, they changed the spelling of English words according to their French ways. French represented the 'kw' sound with QU spelling. To make things more complicated, French people stopped pronouncing the w part, but their spelling never caught up with that change, so words that English borrowed much later, like mystique and quiche, have a 'k' pronunciation instead of 'kw.'

Because of the Romans

So why did the French use QU for 'kw' sounds? Because Latin did. For the 'k' sound, Latin used a Q when it came before a 'w' sound, and a C everywhere else.

Because of the Etruscans

Why did Latin use two different symbols for a 'k' sound? The Romans got their writing system from the Etruscans, who had three different symbols for the 'k' sound: it was gamma (the ancestor of both C and G) before e or i, kappa (ancestor of K) before a, and koppa (ancestor of Q) before u or o.

Because of the Phoenicians

The Phoenicians originated the gamma, kappa, and koppa, but for them, the symbols represented different sounds. The ancestor of Q, koppa, was for a consonant made way in the back of the throat, with the back of the tongue touching the uvula. English doesn't have anything like this sound, but Arabic does, and in borrowings from Arabic (e.g., Qatar, Iraq), English represents it, appropriately, with a Q.

The road from uvular Q to quaint, quirky QU isn't as haphazard as it might seem. The 'u' vowel is produced with the tongue further back in the mouth, so 'k' is slightly further back when it comes before 'u' (compare "key" with "kook"). Q went from standing for a way-back-of-the-throat consonant to a slightly-back-of-the-throat consonant. From there, its pronunciation fate changed from era to era and language to language, but its partnership with U remained strong through the centuries, giving us a tiny window back to the origins of our writing system.

What Is the Shelf Life of Donated Eyes?

Zoe-Anne Barcellos:

I can only answer for cornea and eye donation.

The FDA does all oversight (no pun intended) of organ disposition.

The main organs—heart, liver, pancreas, lungs, etc.—are transplanted within hours. They are just not viable if they are not being perfused constantly.

The other tissues—like bone, skin, tendons, etc.—do not need to be transplanted immediately. But I am not sure on the regulations of when they need to be transplanted.

With the eyes, there are four tissues that can be recovered.

We recover whole eyes for research and education purposes. These usually go much faster, but we can hold them up to a year.

Conjunctiva can also be recovered; conjunctiva is a clear covering over most of the eye (it is what gets irritated when you have pink eye). I have been working as a recovery tech for five years, and our office has not had a request for "conj" in all that time. I believe it is mostly used for research, but I could be wrong.

Sclera is the white area of your eye. It is fairly thick and flexible. If you have ever touched a reptile egg, that is what it reminds me of. We recover sclera for transplant. They use it for several things, but mainly to patch punctures. Similar to if you pop the inner tube of your bike and repair it. Sclera can also be used to repair ear drums. We can hold on to this for up to a year.

The main thing we recover is corneas. In the U.S., we must transplant these within seven days of recovery. (Recovery is usually within hours of death, but we can push it up to 20 hours after if needed.) Sometimes we have more corneas than we need, and then they are shipped overseas and transplanted up to 14 days after recovery. There is no real different outcome with the later transplant time, but the FDA in the U.S. made the rules. (You can sign up to be an organ, tissue, and eye donor here.)

Why Are There No Snakes in Ireland?

Legend tells of St. Patrick using the power of his faith to drive all of Ireland’s snakes into the sea. It’s an impressive image, but there’s no way it could have happened.

There never were any snakes in Ireland, partly for the same reason that there are no snakes in Hawaii, Iceland, New Zealand, Greenland, or Antarctica: the Emerald Isle is, well, an island.

Once upon a time, Ireland was connected to a larger landmass. But that time was an ice age that kept the land far too chilly for cold-blooded reptiles. As the ice age ended around 10,000 years ago, glaciers melted, pouring even more cold water into the now-impassable expanse between Ireland and its neighbors.

Other animals, like wild boars, lynx, and brown bears, managed to make it across—as did a single reptile: the common lizard. Snakes, however, missed their chance.

The country’s serpent-free reputation has, somewhat perversely, turned snake ownership into a status symbol. There have been numerous reports of large pet snakes escaping or being released. As of yet, no species has managed to take hold in the wild—a small miracle in itself.
