The Nazis Were on to Continental Drift Before Everyone Else

“The dream of a great poet.”

“A fairy tale.”

“Delirious ravings.”

“Moving crust disease and wandering pole plague.”

“Germanic pseudoscience.”

In the early 20th century, all these terms—and dozens of other equally colorful ones—were hurled at an emerging scientific idea that we’ve since come to accept as irrefutable and treat as common knowledge.

You may know it as the science of plate tectonics, the explanation of the mechanics of how the puzzle pieces that make up the earth’s surface move around and came to settle (somewhat) into the position they’re in today. In its infancy, though, the idea was known as continental drift, or continental displacement, and was widely regarded by geologists as BS.

Catch My Drift?

Continental drift was proposed by German scientist Alfred Wegener, an untenured and unsalaried lecturer at the University of Marburg. Geology was not his field—he specialized in meteorology and astronomy—but after he became fascinated with the apparent matching coastlines of the various continents while browsing through an atlas, he threw disciplinary boundaries to the wind and pursued his idea. What he proposed was that the continents had once all been joined together in a larger landmass he dubbed the Urkontinent, and was later called  Pangaea (from the Greek pan- (“all”) and gaia (“earth”). At some point in time, the seams running along the supercontinent became unraveled and Pangaea broke into smaller pieces, which drifted, slowly but surely, into their current positions. As evidence, he pointed to live and fossil plants and animals on opposite sides of oceans that were the same or very similar, and geological formations that abruptly ended at the edge of one continent and picked up again on another’s shores.

Wegener first presented his theory of continental drift in a lecture to Frankfurt’s Geological Association in 1912, then in a journal article months later, and finally in a book published shortly after he returned from service in World War I. None of this received very much attention until the book was published in English, at which point Wegener was ridiculed by scientists in Britain, the United States, and even his own country. They poked holes in his evidence and his methods, picked at his credentials, and blasted him for not providing a plausible mechanism powerful enough to actually move the continents.

Wegener worked through the assault, addressing valid criticisms with additional evidence, correcting mistakes, and hypothesizing six different mechanisms for the continents’ drift in new editions of his work. Sadly, he died in 1930 on an expedition to Greenland, decades before his theory began to see widespread acceptance with the discovery of seafloor spreading, Wadati-Benioff zones, and other supporting data and evidence.

Friends in Weird Places

Not all the early reactions to continental drift were harsh, though. In the bizarre intellectual atmosphere of the Third Reich, Wegener’s theory had support and approval from an unlikely champion: the Nazi propaganda machine.

While Nazi science is largely remembered today for its more outrageous ideas and experiments, both real and apocryphal—flying saucers, secret Antarctic bases, talking dogs, supersoldiers, ancient Aryan ruins, and more—the Nazis did come down on the right side of continental drifting before most other geologists did.

Under the Nazis, Deutscher Verlag of Berlin published a bimonthly propaganda magazine called Signal. It was distributed throughout Germany, its allied nations and German-occupied areas in more than 20 languages.  It featured war reports, essays on national socialist policies, German technology innovations, and drawings and photographs, all meant to praise the German government and its allies.

The first issue of 1941, mostly devoted to the German invasion of the Soviet Union, contained a peculiar piece of popular science writing: a two-page article on continental drift. In the piece, titled “And Yet They Do Move,” writer K. von Philippoff defended Wegener’s ideas, citing then-new data that showed an increasing distance between the American and European continents (and replicating one of Wegener’s own mistakes by placing too much emphasis on longitudinal measurements that were not accurate enough at the time to really demonstrate his conclusions) and reminding readers of Wegener’s other evidence, like the scattered flora and fauna and the fit of various continental coastlines. He concluded that continental drift provided a plausible and satisfactory answer to many geological and biological questions that couldn’t otherwise be explained and that “no mistake was possible” about the validity of Wegener’s theory.

While continental drift had a few supporters scattered here and there (like British geologist Arthur Holmes, whose own model of the mechanism for the movement of continents featured an early consideration of seafloor spreading), von Philippoff’s article is notable in that its presence in an official German propaganda magazine, reflecting the views of the government, implies approval and support by at least some members of the Nazi higher-ups. For all the horror and suffering they unleashed upon the world, history’s greatest villains were at least far ahead of their time in the field of geology.

Ancient Poop Contains First Evidence of Parasites Described by Hippocrates

The long-held mystery of Hippocrates and the parasitic worms has finally been solved, and it’s all thanks to a few samples of ancient poop.

Researchers don’t know much about the parasites that plagued the Greeks thousands of years ago, and what they do know is largely from the Hippocratic Corpus, the medical texts that the father of medicine and his students put together between the 4th and 3rd centuries BCE. Modern historians have spent years trying to figure out which diseases and parasites Hippocrates and his followers were referring to in their writing, relying solely on their descriptions to guess at what ailments the ancient Greeks might have suffered from. Now, they finally have concrete evidence of the existence of some of the intestinal worms Hippocrates mentioned, Helmins strongyle and Ascaris.

As part of a study in the Journal of Archaeological Science: Reports, an international group of researchers analyzed the ancient remains of feces in 25 prehistoric burials on the Greek island of Kea to determine what parasites the people were carrying when they died. Using microscopes, they looked at the soil (formed by the decomposed poop) found on the pelvic bones of skeletons dating back to the Neolithic, Bronze, and Roman periods.

Around 16 percent of the burials they studied contained evidence of parasites. In these ancient fecal samples, they found the eggs of two different parasitic species. In the soil taken from the skeletons dating back to the Neolithic period, they found whipworm eggs, and in the soil taken from the Bronze Age skeletons, roundworm.

With this information, researchers deduced that what Hippocrates called the Helmins strongyle worm was probably what modern doctors would call roundworm. The Ascaris worm probably referred to two different parasites, they conclude, known today as pinworm (which was not found in this analysis) and whipworm (pictured below).

Though historians already hypothesized that Hippocrates's patients on Kea had roundworm, the Ascaris finding comes as a particular surprise. Previous research based solely on Hippocrates’s writing rather than physical evidence suggested that what he called Ascaris was probably a pinworm, and another worm he mentioned, Helmins plateia, was probably a tapeworm. But the current research didn’t turn up any evidence of either of those two worms. Instead of pinworm eggs, the researchers found whipworm, another worm that’s similarly small and round. (Pinworms may very well have existed in ancient Greece, the researchers caution, since evidence of their fragile eggs could easily have been lost to time.) The soil analysis has already changed what we know about the intestinal woes of the ancient Greeks of Kea.

More importantly, this study provides the earliest evidence of ancient Greece’s parasitic worm population, proving yet again that ancient poop is one of the world’s most important scientific resources.

Arctic Temperatures are Rising So Fast, They're Confusing the Hell Out of Computers

This past year was a brutal one for northern Alaska, which saw temperatures that soared above what was normal month after month. But you wouldn't know that by looking at the numbers from the weather station at Utqiaġvik, Alaska. That's because the recent heat was so unusual for the area that computers marked the data as incorrect and failed to report it for the entirety of 2017, leaving a hole in the records of the Climate Monitoring group at the National Centers for Environmental Information (NCEI), according to the Huffington Post.

The weather station in the northernmost tip of Alaska has been measuring temperatures for nearly a century. A computer system there is programed to recognize if the data has been influenced by artificial forces: Perhaps one of the instruments isn't working correctly, or something is making the immediate area unnaturally hot or cold. In these cases, the computer edits out the anomalies so they don't affect the rest of the data.

But climate change has complicated this failsafe. Temperatures have been so abnormally high that the Utqiaġvik station erroneously removed all its data for 2017 and part of 2016. A look at the region's weather history explains why the computers might have sensed a mistake: The average yearly temperature for the era between 2000 and 2017 has gone up by 1.9°F from that of the era between 1979 and 1999. Break it down by month and the numbers are even more alarming: The average temperature increase is 7.8°F for October, 6.9°F for November, and 4.7°F for December.

"In the context of a changing climate, the Arctic is changing more rapidly than the rest of the planet," Deke Arndt, chief of NOAA's Climate Monitoring Branch, wrote for The higher temperatures rise, the faster Arctic sea ice melts. Arctic sea ice acts as a mirror that reflects the Sun's rays back into space, and without that barrier, the sea absorbs more heat from the Sun and speeds up the warming process. “Utqiaġvik, as one of a precious few fairly long-term observing sites in the American Arctic, is often referenced as an embodiment of rapid Arctic change,” Arndt wrote.

As temperatures continue to grow faster than computers are used to, scientists will have to adjust their algorithms in response. The team at NCEI plans to have the Utqiaġvik station ready to record our changing climate once again within the next few months.
