The annual spring peeper hocus pocus

(While our host convalesces, here is one of his essays from the archive. This musing originally appeared in The Boston Globe, 22 April 1991. —Tom)

The spring peepers are in full fortissimo chorus.

On Nantucket they call these noisy little frogs pinkletinks, presumably because that’s how Nantucketers hear the sound. I’m not sure how I’d describe the peeper’s call. Pinkletink doesn’t do justice to the volume. Not peep-peep either. The peeper’s voice is shrill and high pitched, and when the water meadow is in heady voice it’s like a zillion wedding guests clanking on glassware with spoons.

The peeper is only an inch long, but it’s all voice box from stem to stern. Most frogs call by inflating air sacs under their chins; peepers inflate their whole bodies. The air is not expelled with each peep. The peeper uses its body like a bagpiper’s bag; keeps it pumped up for the duration of its amatory calls.

This year the chorus began on March 28. A week later I stood by the side of the water meadow and the whole place seemed to sing. You’d swear they were everywhere; a carpet of sound stretched away from my feet. But not a peeper to be seen. I scanned the water with binoculars. The weeds and the bushes. Not a sign of the elusive frogs. Pure, disembodied pandemonium. The water itself seemed to be emitting the noise.

Off with the shoes. Roll up the trousers. Into the water. Out to the very middle of the water meadow. Silence, as if someone has pulled the plug on the amplifier. I stand still as a statue. Five minutes, ten. Then, it starts up again, that ear-splitting carpet of sound. The peepers are still invisible.

It’s the male frog making all the noise, and we know why. It’s that old spring business all over again: finding a mate. But why the tumultuous decibels? Why the din? Is the female peeper deaf? Does she choose a mate by the amplitude of his call? Has evolution cranked up the volume of this chorus by finding some connection between the loudness of the love song and reproductive fitness?

Or is it something else, something you won’t find in the biology books—pure excess vitality, a capacity of water and muck to make noise, to celebrate.

Of course I’m being facetious, but not altogether so. I’m talking about the astounding resiliency of life, its ability to survive the harshest conditions and to spring up in the unlikeliest places. The Roman naturalist Pliny the Elder wondered about all those frogs coming out of nowhere in the spring with their outrageous racket, and attributed it to an “occult operation” by nature. In other words, magic. Slight-of-hand. Hocus-pocus.

We are more hardheaded about it. We know the peepers have been there all along, buried in the mud throughout the long winter, just waiting for a couple of warm days to beckon them up into song. But what about life itself? What “occult operation” of nature conjured up life on the Earth nearly 4 billion years ago, out of water and muck? One minute the planet was lifeless (presumably), and the next minute (give or take a few tens of millions of years) the whole place was swimming with microbes—and it’s been swimming ever since.

Most biologists believe that life began spontaneously from non-living materials. Darwin imagined it happened in a “warm little pond” somewhere on the early Earth—the quietly simmering primeval soup so dear to generations of biologists. According to this theory, chemicals stewing in water formed themselves into proteins, RNA, DNA, and ultimately the first living cells.

But Darwin’s warm little pond may never have existed. Recently, planetary scientists have been telling us that Earth was a nasty place back at about the time life was starting. The surface of the planet was subject to rampant volcanism. Meteorites rained from the sky for hundreds of millions of years, the same incessant bombardment that pulverized the surface of the moon (on Earth the evidence of that early bombardment has been erased by erosion and tectonic activity). A few meteorites may have carried enough energy to completely vaporize the oceans.

It’s hard to imagine how or where in the midst of such chaos the complex and delicate structures of life were created and sustained. Perhaps it happened near volcanic fissures on the floors of the deepest oceans, even as the meteorites pelted down. Or perhaps in hot springs on continents as the bombardment waned.

Since no one knows how life began, I’ll opt for the theory that it was all more or less inevitable. Start with a hydrogen-rich environment, throw in some carbon, expose it to energy, and—presto!—you’ve got amino acids, phosphates, sugars, and organic bases, the chemical building blocks of life. Add cycles of heat and cold, dry and wet, light and darkness, maybe a catalyst like iron pyrites or clay, and any old planet with a reasonably moderate environment will pull the rabbit out of the hat. Or the peepers out of the pond.

I can’t prove it but I choose to believe that water and muck has a built-in tendency toward animation, and that life is ubiquitous, not only here but throughout the universe. I don’t mean to sound mystical, but if we’ve learned anything in the 20th century it is that matter—plain old matter—is subtle stuff, rich in possibilities of combination.


Just listen to that racket rising from the water meadow. That’s what the spring peepers’ hallelujah chorus is all about: the sheer, unstoppable ebullience of life.

What is Protomyxzoa Rheumatica?

A contact on Twitter mentioned an apparently newly discovered parasitic disease which goes by the name of Protomyxzoa Rheumatica or the “Fry bug”, named for its apparent discoverer Fry Laboratories of Scottsdale, Arizona. The discoverers have published no scientific papers about this organism as far as I can tell. Although protomyxzoa.org (registered in September 2012) says Fry has a PCR test for the pathogen and the person running the site says they were diagnosed by the labs in February of that year.

No reference to Protomyxzoa Rheumatica comes up with a search of the Fry website nor of PubMed, the US CDC, WHO, WebMD or generally anywhere else other than on what appear to be a few patient blogs and such. There is a brief reference to Protomyxzoa Rheumatica on the website of Fry Labs’ founder http://drstephenfry.com/ where it is described as a: novel protozoan but nothing else is said. Dr Fry himself is described as specialising in the cause and treatment of chronic inflammatory disease such as chronic fatigue syndrome (CFS) and fibromyalgia. There is also discussion of diet and lifestyle being associated with the “symptoms” of this infection. A “Mary C Kline” appears in a patent search having invented a treatment for treating the biofilms and plaques purportedly associated with the infection, her other patents seem to be for treatments for what would be described as related pathogens.

There is one slightly more detailed page – http://www.personalconsult.com/posts/FL1953.html – that uses another name (an earlier name, in fact) for Protomyxzoa Rheumatica, FL1953, and discusses it in terms of its similarity to babesia (nutallia) or immature malaria but apparently unique DNA sequence. (FL1953 does not come up in a PubMed search either). The page also discusses how Fry showed the page’s author stained red blood cells apparently infected with Protomyxzoa Rheumatica in which the organism was on the edge or inside the rbc. Misdiagnosis of this novel infection is why treatment of Lyme disease and Babesia sometimes fail allegedly. Another patient-written site discusses a talk/interview given by Fry where FL1953 is described as “a new, unique protozoan organism that is found in people with CFS, fibromyalgia, multiple sclerosis, ALS, and rheumatoid arthritis”. There is a lot of debate on LymeNet Europe that suggests that FL1953 has been controversial to say the least for several years.

One particular claim draws me to an almost inevitable conclusion regarding this pathogen. There are references to Morgellons syndrome in connection with FL1953. Morgellons, however, is apparently nothing more than a psychosomatic illness in which the patient believes that they are infested with disease-causing agents described as things like insects, parasites, hairs or fibres. While it may be a real condition it is not, it seems, caused by an actual pathogen, unless of course, that pathogen has corrupted the patient’s thoughts to create these beliefs (some parasites certainly can affect the brain).

I asked an expert in Lyme disease and related infections who had this to say: The owner of a private lab has claimed to have identified a new organism which causes many disorders including autoimmune. He apparently planned to conduct studies on this, but there have been no updates nor any peer-reviewed journal publications about it…in the meantime lots of people are being diagnosed with an illness no one knows for sure even exists…

A More Reality-Based Poll

Remember that strikingly inept poll analysis about the Tea Party movement from The New York Times last month? Well, the new Washington Post-ABC News poll addresses the same topic, and the Post’s analysis seems to actually be rooted in reality:

The conservative “tea party” movement appeals almost exclusively to supporters of the Republican Party, bolstering the view that the tea party divides the GOP even as it has energized its base.

That conclusion, backed by numbers from a new Washington Post-ABC News poll, also suggests that the tea party may have little room for growth. Most Americans — including large majorities of those who don’t already count themselves as supporters — say they’re not interested in learning more about the movement. A sizable share of those not already sympathetic to the tea party also say that the more they hear, the less they like the movement.

Overall, the tea party remains divisive, with 27 percent of those polled saying they’re supportive but about as many, 24 percent, opposed. Supporters overwhelmingly identify themselves as Republicans or GOP-leaning independents; opponents are even more heavily Democratic. The new movement is also relatively small, with 8 percent of supporters claiming to be “active participants” — about 2 percent of the total population.

(Emphasis added by me.)

These numbers are somewhat similar to last month’s New York Times-CBS News poll, which found that 18% of Americans support the Tea Party movement. Despite the Times doing as much as it could to hype these results, I pointed out that this wasn’t very meaningful, since that poll found that 78% of these “supporters” had never attended a Tea Party rally or meeting or donated money to the Tea Party cause. So, doing a little math, we find that about 4% of people could be labeled as active Tea Partiers based on that poll (compared with 2% in the current Washington Post poll).

The difference in both of these numbers (27% vs. 18% for supporters, 4% vs. 2% for active participants) could be due to a real drop in support for and participation in the Tea Party movement, or just a difference between the two polls. My point in bringing it up is that The Washington Post’s analysis actually makes sense.

On the side, it is also of note that there’s some good news in the poll for the Democratic Party:

The percentage of people who say the Democratic Party represents their personal values and is in tune with the problems of people like themselves hasn’t changed since November. The percentage siding with the GOP, however, has dropped by almost precisely the numbers now siding with the tea party.

Some 14 percent of Americans say the tea party is most in sync with their values, nearly matching the 15 percentage-point drop-off for the GOP over the past five months.

This Is a Very Dumb Poll

Actually, I should say that this is a very dumb analysis of a poll. The New York Times is really promoting its new NYT/CBS poll right now; as I write this, the top headline on the Times’ homepage reads “Poll Finds Tea Party Backers Wealthier and More Educated.”

When I first saw that headline and read the email news alert that the Times sent out, I did agree that these appeared to be interesting and surprising findings. And, as I read the article, my interest–and then skepticism–continued to grow. According to the article, these “Tea Party supporters” are “wealthier and more well-educated than the general public”, and they make up “18 percent of Americans”. Hmmm… interesting. Also, they “do not think Sarah Palin is qualified to be president”, and are “more likely than the general public to have returned their census forms.” Well, that’s quite a surprise.

The article goes on and on, but one thing should become clear: these “Tea Party supporters” sound almost indistinguishable from your run-of-the-mill establishment fiscal-conservative Republican. How could this be?

Well, if you look at the actual the survey results and methods, you’ll see that these “Tea Party supporters” are just people who answered affirmatively to the question “Do you consider yourself to be a supporter of the Tea Party movement, or not?” In fact, 78% (!!!) of these “supporters” have never attended a Tea Party rally or meeting or donated money to the Tea Party cause.

It’s no wonder that these “Tea Party supporters” sound nothing like the Tea Party activists we’ve grown so familiar with… because they’re not! Now, I’ll grant that the Times’ analysis never explicitly equates these two. But, especially by making statements like “Speculation and anecdotal evidence have often taken the place of concrete data about who supports the Tea Party movement, and the poll offers some surprising findings”, they’re really insinuating a lot.

In the end, these results are pretty uninteresting, since this poll just describes a large bloc of the Republican Party that has been in existence for a long time. (For a much more reasonable analysis of the poll, check out CBS’s take.)

For a more relevant picture of what the Tea Party movement actually looks like, just take this recent sampling from the Times’ own pages:

Let’s not mince words here: the Tea Party movement has been fueled by misinformation, bigotry, and irrational violent anger at the government. If this new poll shows us anything, it’s just to what a large degree the Republican establishment has accepted and embraced this radical fringe.

Are happy kids dumb kids?

Did you live a coddled childhood filled with unbridled playtime and few reminders of the harsh real world? You might have been dumber as a result.

Children coaxed into a jovial mood performed worse on a simple test of geometric shape recognition than kids put in a dourer mood, report Simone Schnall, of the University of Plymouth, UK and colleagues in a recent issue of Developmental Science.

You may wonder whether these psychologists hate happy kids or just fun, but their conclusion is supported by other research. For instance, adults in good spirits do worse than sad adults on similar tests.

To uncover the same effect in children, the researchers, thankfully, didn't resort to insults or mind-altering drugs.

Instead they played one of two classical tunes to 10- and 11-year olds. Fifteen kids heard Mozart's jolly ditty Eine Kleine Nachtmusik, while the other 15 had to suffer through Mahler's doleful Adagietto. Previous research suggested these songs put kids in happy and sad moods, respectively, and Schnall's team confirmed that by surveying the kids.

While listening to the tunes the children played a game where they hunted for a specific geometric shape – a triangle joined to a rectangle, for instance – within a picture. The merry Mozart kids took noticeably longer finding the shapes than the children who were forced to listen to Mahler.

Not content with proving that happy pre-teens are daft, the researchers aimed their hypothesis at 61 six and seven-year olds. Instead of hearing classical music, the kids watched three movie scenes.

One, from Disney's Jungle Book, features the singing and dancing of an ebullient bear. A neutral scene from The Last Unicorn shows a knight reaching a castle. The sad scene comes from The Lion King, another Disney cartoon. Even this reporter, who watched the movie as a teen, shed a tear when Simba mourns his father's death.

In the same shape recognition test administered after the movie scene, the happy kids proved slower at picking out shapes than those who watched the neutral Last Unicorn or the lugubrious Lion King scenes.

Schnall's team offers several explanations for their results. Mood could directly alter cognitive thinking, and in a happy state people have little desire to question what they see, while "sadness indicates something is amiss, triggering detail-oriented analytical processing," they write.

Alternatively, happy people could be so caught up in their personal high that they ignore details or they distract themselves from the task at hand.

This could be hand-waving - it seems just as likely that Mozart and The Jungle Book are more distracting than Mahler and The Lion King. Because the kids tended to ignore the music played before the test, the researchers dismiss this possibility, but anyone who's taken a six-year old to a Disney film knows that the catchy songs don't vanish from their brains in just a few minutes.

But there's some encouraging news, at least, for cheerful kids and their parents. Children in a good mood perform better on tasks that demand creative and flexible thinking, previous studies show.

So the take-home message may be - contrary to popular opinion - that happy kids end up as artists and poets, while sad and angry children become accountants.

The paper's last sentence seems directed toward parents of these future artists: "Artificially inflating a child's mood may have unintended and possibly undesirable cognitive consequences."
