Graham Burnett wrote a fascinating essay in Cabinet recently about otolithic organs, the pair of sensors in the inner ear that help us stay balanced and maintain inertia. "Grossly speaking," writes Burnett, the otolithic organs consist of "a bunch of tiny pebbles (of the white rock known as calcium carbonate) embedded in a gooey wad that sits atop a carpet of delicate hairs." In humans, those "pebbles" are practically microscopic, but in fish, they can be as large as marbles:
There are several thousand researchers around the world who spend their whole working day looking at fish otoliths. This has nothing to do with their physiological functions, however, and everything to do with their structure and the staggering amount of information they contain. In the first place, each species of fish has a unique otolith shape. Couple this with the fact that they are stone (and therefore comparatively resistant to decomposition), and their utility as a biological marker becomes clear. Interested in the food habits of bottlenose whales? Pump their stomachs and you will end up with relatively few bones but lots of otoliths. Find an otolith expert and he or she will be able to give you a menu...
But the true wonder of these peculiar pearls lies within. Should you have occasion to tonsure a snapper or sea-bass, slicing off the top of its skull just above the eyes, you might take a moment to remove the two largest otoliths (there are, as a rule, six in all, three on each side) from their velvet seats to the right and left of the brain stem. With the heel of a knife you should be able to snap one of them in two, and then, holding it to the light, you will discern a set of concentric bands. These are growth rings--annuli--which, properly counted, will give the age of your fish in years.
In the late 1960s and 1970s, the mind-expanding modus operandi of the counterculture spread into the realm of science, and shit got wonderfully weird. Neurophysiologist John Lilly tried to talk with dolphins. Physicist Peter Phillips launched a parapsychology lab at Washington University. Princeton physicist Gerard O’Neill became an evangelist for space colonies. Groovy Science: Knowledge, […]
In a lead editorial in the current Nature, John Wilbanks (formerly head of Science Commons, now “Chief Commons Officer” for Sage Bionetworks) and Eric Topol (professor of genomics at the Scripps Institute) decry the mass privatization of health data by tech startups, who’re using a combination of side-deals with health authorities/insurers and technological lockups to […]
The Wall Street Journal reports that storytellers—people with a natural inclination to craft concise yet compelling narratives without rambling—were found to be hot by science. Feels good to be a writa. The results were the same across all three studies: Women rated men who were good storytellers as more attractive and desirable as potential long-term […]
