The NY Times contains a Science section on Tuesdays, and it always has delightful tidbits. Today Sindya N. Bhanoo writes that if you had music lessons at a young age, the experience may benefit you in old age.

“A new study reports that older adults who took lessons at a young age can process the sounds of speech faster than those who did not.

“ ‘It didn’t matter what instrument you played, it just mattered that you played,’ said Nina Kraus, a neuroscientist at Northwestern University and an author of the study, which appears in The Journal of Neuroscience.

“She and her collaborators looked at 44 healthy adults ages 55 to 76, measuring electrical activity in a region of the brain that processes sound.

“They found that participants who had four to 14 years of musical training had faster responses to speech sounds than participants without any training — even though no one in the first group had played an instrument for about 40 years.” More here.

Now, of course, I am looking back and trying to count how many years of piano lessons I had as a kid. I’m sure it was at least the four Kraus deems necessary. But I hardly ever practiced, so probably the effect was small.

Doubtless you know about fairy circles, also called fairy rings. According to Wikipedia, they’re a “naturally occurring ring or arc of mushrooms. The rings may grow to over 10 metres (33 ft) in diameter, and they become stable over time as the fungus grows and seeks food underground.

“They are found mainly in forested areas, but also appear in grasslands or rangelands. Fairy rings are detectable by sporocarps in rings or arcs, as well as by a necrotic zone (dead grass), or a ring of dark green grass. If these manifestations are visible a fairy fungus mycelium is likely to be present in the ring or arc underneath.

“Fairy rings also occupy a prominent place in European folklore as the location of gateways into elfin kingdoms.”

But in Africa, there is a different kind of fairy circle that doesn’t seem to have anything to do with mushrooms.

Did you catch the article by Sindya Bhanoo in the NY Times?

“The grasslands of Namibia — and to a lesser extent its neighbors Angola and South Africa — are speckled with millions of mysterious bare spots called ‘fairy circles,’ their origins unknown.

“Now, a study based on several years of satellite images describes the circles’ life span as they appear, transform over decades, and then eventually disappear.

“Writing in the journal PLoS One, Walter R. Tschinkel, the study’s author and a biologist at Florida State University, reports that the circles can last 24 to 75 years.

“The circles, which range from about 6 to 30 feet in diameter, begin as bare spots on an otherwise continuous grass carpet; after a few years, taller grass starts to grow around the circle’s perimeter.”

The reader is left with the question, Are these circles gateways to elfin kingdoms? What kind of elves are in Namibia?

I don’t understand why scientists don’t investigate matters like that.
