“The poets have been mysteriously silent on the subject of cheese”*…

The blue-green marbling of fungus that makes Blue (or as purists might have it, Bleu) Cheese blue is a delight to some, but a horror to others.  Now Roquefort-refusers have a new reason to demur…

Until pretty recently, a big chunk of fungal species were thought to reproduce without sex–until people really started to look. It turns out, there’s a lot more sex going on in the fungal world (on the down-low) than people thought. And that includes fungi that are used to make delicious blue cheese. Jeanne Ropars and colleagues in France, the home of Roquefort cheese, looked at the genomes of the mold species used in this particular cheese to see what kind of funny business was going on in their snack of choice. They found much more diversity than could be explained by asexual reproduction. And even more telling, the genes used by fungi to find mating partners have been kept intact and functional by evolution, meaning there’s probably some sex going on…

So far, no one has actually seen this mold having sex. But it could be. It could be doing it right now. Who knows what kind of awesome super-cheese could be evolving, right under your nose?

Read the full story at Molecular Love (and Other Facts of Life); and find the research paper to which it refers here.

As we put away the saltines, we might send inventive birthday greetings to David Wilkinson; he was born on this date in 1771.  A mechanical engineer and machinist, Wilkinson (no known relation to your correspondent) played a key role in the development of machine tools in the U.S. (initially in the textile industry):  he invented the lathe and process for cutting screws.

Who owns the fish?…

From the good folks at Coudal Partners, a puzzle purportedly created by Albert Einstein…

There are five houses in a row in different colors. In each house lives a person with a different nationality. The five owners drink a different drink, smoke a different brand of cigar and keep a different pet, one of which is a Walleye Pike.

The question is– who owns the fish?

Hints:
1. The Brit lives in the red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The green house is on the left of the white house.
5. The green house owner drinks coffee.
6. The person who smokes Pall Malls keeps birds.
7. The owner of the yellow house smokes Dunhills.
8. The man living in the house right in the center drinks milk.
9. The man who smokes Blends lives next to the one who keeps cats.
10. The Norwegian lives in the first house.
11. The man who keeps horses lives next to the one who smokes Dunhills.
12. The owner who smokes Bluemasters drinks beer.
13. The German smokes Princes.
14. The Norwegian lives next to the blue house.
15. The man who smokes Blends has a neighbor who drinks water.

There’s nothing up anyone’s sleeve (as though fish had sleeves…); and everything one needs to know is there.

Successful solutions can be confirmed here.  And readers can find a second fish puzzle here, and a little teaser called “Da Vinci’s Other Code” here.

As we scratch our heads, we might wish a Joyeux Anniversaire to silk weaver Joseph Marie Jacquard; he was born on this date in 1752.  Jacquard’s 1805 invention of the programmable power loom, controlled by a series of punched “instruction” cards and capable of weaving essentially any pattern, ignited a technological revolution in the textile industry… indeed, it set off a chain of revolutions: it inspired Charles Babbage in the design of his “Difference Engine” (the ur-computer), and later, Herman Hollerith, who used punched cards in the “tabulator” that he created for the 1890 Census… and in so doing, pioneered the use of those cards for computer input.
