Why East Germany is a map zombie
Three decades after the demise of the GDR, its familiar contours keep coming back from the dead.
- East Germany has been dead for a little more than three decades.
- But the former GDR just keeps popping up on all kinds of maps.
- It's a sign that life in the east of Germany is still very different from the west.
Forgotten, but not gone

The GDR may be forgotten, but it's not gone. Apart from a shrinking handful of diehard nostalgics, nobody mourns the passing of the German Democratic Republic, as communist East Germany (1949-1990) was officially known.
It became such an exemplar of the chasm between the high ideals and grim reality of Soviet-style socialism that the regime literally had to fence in its citizens to keep them from running away. Up until the building of the Berlin Wall (1961), hundreds of East Germans each day 'voted with their feet', defecting to West Germany – decadent and capitalist, yes; hence also a lot more fun.
Inevitably, the fall of the Wall in 1989 was the death-knell for East Germany. We've just passed the 30th anniversary of German reunification, which came into effect on October 3, 1990. But after three decades of painful economic, political, and cultural adjustments, the ghost of East Germany lingers on the map.
Like secret messages that become visible under UV light, the contours of the GDR come out when you apply the right data filters. And not just once or twice. Again and again, we see the old (and to some, familiar) borders emerge. In other words, the German Democratic Republic is a map zombie. That's because life continues to be different in former East Germany – even if it's now just the east of Germany.
Below are some examples, selected from the Facebook group with the self-explanatory name: East Germany is discernibly visible on this relatable map.
The unhappy east

East Germans are less happy than their western compatriots. Out of a maximum of 10 on the happiness scale, most of the former GDR colors red (below 7.2), the rest orange (between 7.2 and 7.4).
In the west, few areas are orange and none are red. Most areas are yellow-happy (7.4 to 7.6), and light-green-happy (7.6 to 7.7). Southern Bavaria (dark green; 7.7 and up) is the happiest corner of Germany.
Too bourgeois for the GDR?

In the old Soviet bloc, sports were a propaganda tool, and athletic excellence a way to prove the regime's supremacy on the world stage.
But apparently, tennis was not the right vehicle – perhaps the East German communists thought it too bourgeois. That would explain why there is such a marked difference between east and west when it comes to the distribution of tennis courts.

Thirty years after reunification, Germany's economy remains unbalanced along familiar lines. This map shows the averages for gross monthly wages: below €3000 in red areas (below €2500 in dark red zones). Almost all of the light red areas are in the east, none of the dark red ones are in the west.
Tantalizingly, Germany's highest-earning area (Wolfsburg, €5089) is right on the former East German border, next to an area with half the average wages. Car aficionados will recognize the name of the city as the home of Volkswagen HQ and the world's largest car plant.
Too many Ronnies
Democratic Republic of Ronnyland.
Older British TV viewers will remember a comic duo called "The Two Ronnies." If they had been German comedians, their names would have immediately pegged them as Ossis (eastern Germans).
'Ronny' is as popular in the east as it isn't in the west. In the eastern German state of Saxony-Anhalt (the dark-blue area on the map), between 66 and 78 out of 10,000 Facebook users carry that first name. In the rest of the former GDR (the middle-blue area), it's 54 to 66. In almost all of western Germany, the rate is below 18.
More public childcare
In the east, more than half the kids under three attend publicly-funded daycare.
The legacy of the communist past isn't all bad, it seems. Some collectivist traditions and provisions survive. Like more public childcare. This map shows the share of under-threes going to publicly-funded daycare centers: over 50 percent in most of the former GDR.
Mosques vs. hazelnut spread
Like twins separated at birth, east and west developed fascinating differences.
Like one of those sets of twins separated at birth, East and West Germany are a fascinating study in similarities and differences – some large, some small. The economic powerhouse that West Germany became needed foreign workers. Many came from Turkey, as evidenced by this map of mosques in Germany: only a handful are in the east.
In its decades alone, East Germany developed a range of household products, often barely disguised copies of western consumer goods. Many are on display in Berlin's DDR Museum. Nudossi, often dismissively called 'Ost-Nutella', is one of the rare brands that survived reunification. Perhaps that's because the spread contains 36 percent hazelnuts, almost three times the amount of actual Nutella (13 percent). Still, Wessis (western Germans) are clearly less keen on the stuff.
Far left, far right

Voting patterns in the east tend to be more eccentric in the east. The map on the left shows the results for the 2013 federal elections of Die Linke (the Left Party), which positions itself firmly to the left of the SPD, the mainstream social-democratic party. Die Linke garnered between 20 percent and a quarter of the votes right across the former GDR, and was nowhere near as successful anywhere else in Germany.
More recently, the right-wing populists of Alternative für Deutschland (AfD) have found a lot of support in the east. The undated map shows voting intentions for recent upcoming state elections. AfD is particularly strong in the south of the former GDR (26 percent in Saxony, 22 percent in Thuringia). Its highest score in the west is 11.6 percent in Baden-Württemberg.
Catholic, Protestant and None
'Nones' are the majority throughout East Germany.
Confessionally, Germany also remains a divided nation. This map shows which religion dominates where. Catholics predominate in the south and west (dark red: majority, light red: plurality). Protestants are a majority in the north and middle (dark blue), a plurality in the southwest (light blue).
East Germany is easily discernible: it's the part where the main religious affiliation is 'none'. That also includes the whole of Berlin (including the western half), plus the western cities of Hamburg and Frankfurt.
Poor overall, but not poorest overall

The former GDR has a consistently high poverty rate: an average of 17.5 percent throughout all six Länder (states). But there's a silver lining, of sorts: the poverty rate is even higher in the western state of North Rhine-Westphalia (18.1 percent), which contains the Ruhrgebiet, a.k.a. Germany's Rust Belt.
The R1a haplogroup is a genetic marker associated with Slavic populations.
The former border between East and West Germany mirrors a much older one: the western extent of the Slavic zone around the year 1000. This map shows the spread of the R1a haplogroup among locals.
This genetic marker is associated with Slavic populations. It is prevalent throughout the former GDR, particularly the south – and in eastern Austria, by the way. R1a 'islands' further west may be the result of more recent immigration waves, by Polish guest workers for example.
Streetcars and streetlights
In Berlin, the past is never dead. In fact, it's not even past.
And finally, two images that zoom in on Berlin. Now the reunified capital of a reunified country, before 1990 it was as divided as Germany itself. And that is still visible, if you know where to look.
At the map of Berlin's streetcars (top), for example. West Berlin never took the step to restore the pre-war streetcar network on its territory. East Berlin did. And that's still the case – with one exception: a single line was extended from the east to the west, a rare example of the west adopting anything 'eastern'.
When night falls, the division between east and west can still be seen from the sky. In the east, street lights use sodium vapor lamps, providing a warm orange glow. In the west, the lamps are fluorescent, resulting in a brighter yellow light.

Strange Maps #1063

Certain water beetles can escape from frogs after being consumed.
- A Japanese scientist shows that some beetles can wiggle out of frog's butts after being eaten whole.
- The research suggests the beetle can get out in as little as 7 minutes.
- Most of the beetles swallowed in the experiment survived with no complications after being excreted.
In what is perhaps one of the weirdest experiments ever that comes from the category of "why did anyone need to know this?" scientists have proven that the Regimbartia attenuata beetle can climb out of a frog's butt after being eaten.
The research was carried out by Kobe University ecologist Shinji Sugiura. His team found that the majority of beetles swallowed by black-spotted pond frogs (Pelophylax nigromaculatus) used in their experiment managed to escape about 6 hours after and were perfectly fine.
"Here, I report active escape of the aquatic beetle R. attenuata from the vents of five frog species via the digestive tract," writes Sugiura in a new paper, adding "although adult beetles were easily eaten by frogs, 90 percent of swallowed beetles were excreted within six hours after being eaten and, surprisingly, were still alive."
One bug even got out in as little as 7 minutes.
Sugiura also tried putting wax on the legs of some of the beetles, preventing them from moving. These ones were not able to make it out alive, taking from 38 to 150 hours to be digested.
Naturally, as anyone would upon encountering such a story, you're wondering where's the video. Thankfully, the scientists recorded the proceedings:
The Regimbartia attenuata beetle can be found in the tropics, especially as pests in fish hatcheries. It's not the only kind of creature that can survive being swallowed. A recent study showed that snake eels are able to burrow out of the stomachs of fish using their sharp tails, only to become stuck, die, and be mummified in the gut cavity. Scientists are calling the beetle's ability the first documented "active prey escape." Usually, such travelers through the digestive tract have particular adaptations that make it possible for them to withstand extreme pH and lack of oxygen. The researchers think the beetle's trick is in inducing the frog to open a so-called "vent" controlled by the sphincter muscle.
"Individuals were always excreted head first from the frog vent, suggesting that R. attenuata stimulates the hind gut, urging the frog to defecate," explains Sugiura.

Are "humanized" pigs the future of medical research?
The U.S. Food and Drug Administration requires all new medicines to be tested in animals before use in people. Pigs make better medical research subjects than mice, because they are closer to humans in size, physiology and genetic makeup.
In recent years, our team at Iowa State University has found a way to make pigs an even closer stand-in for humans. We have successfully transferred components of the human immune system into pigs that lack a functional immune system. This breakthrough has the potential to accelerate medical research in many areas, including virus and vaccine research, as well as cancer and stem cell therapeutics.
Existing biomedical models
Severe Combined Immunodeficiency, or SCID, is a genetic condition that causes impaired development of the immune system. People can develop SCID, as dramatized in the 1976 movie “The Boy in the Plastic Bubble." Other animals can develop SCID, too, including mice.
Researchers in the 1980s recognized that SCID mice could be implanted with human immune cells for further study. Such mice are called “humanized" mice and have been optimized over the past 30 years to study many questions relevant to human health.
Mice are the most commonly used animal in biomedical research, but results from mice often do not translate well to human responses, thanks to differences in metabolism, size and divergent cell functions compared with people.
Nonhuman primates are also used for medical research and are certainly closer stand-ins for humans. But using them for this purpose raises numerous ethical considerations. With these concerns in mind, the National Institutes of Health retired most of its chimpanzees from biomedical research in 2013.
Alternative animal models are in demand.
Swine are a viable option for medical research because of their similarities to humans. And with their widespread commercial use, pigs are met with fewer ethical dilemmas than primates. Upwards of 100 million hogs are slaughtered each year for food in the U.S.
In 2012, groups at Iowa State University and Kansas State University, including Jack Dekkers, an expert in animal breeding and genetics, and Raymond Rowland, a specialist in animal diseases, serendipitously discovered a naturally occurring genetic mutation in pigs that caused SCID. We wondered if we could develop these pigs to create a new biomedical model.
Our group has worked for nearly a decade developing and optimizing SCID pigs for applications in biomedical research. In 2018, we achieved a twofold milestone when working with animal physiologist Jason Ross and his lab. Together we developed a more immunocompromised pig than the original SCID pig – and successfully humanized it, by transferring cultured human immune stem cells into the livers of developing piglets.
During early fetal development, immune cells develop within the liver, providing an opportunity to introduce human cells. We inject human immune stem cells into fetal pig livers using ultrasound imaging as a guide. As the pig fetus develops, the injected human immune stem cells begin to differentiate – or change into other kinds of cells – and spread through the pig's body. Once SCID piglets are born, we can detect human immune cells in their blood, liver, spleen and thymus gland. This humanization is what makes them so valuable for testing new medical treatments.
We have found that human ovarian tumors survive and grow in SCID pigs, giving us an opportunity to study ovarian cancer in a new way. Similarly, because human skin survives on SCID pigs, scientists may be able to develop new treatments for skin burns. Other research possibilities are numerous.

Pigs in a bubble
Since our pigs lack essential components of their immune system, they are extremely susceptible to infection and require special housing to help reduce exposure to pathogens.
SCID pigs are raised in bubble biocontainment facilities. Positive pressure rooms, which maintain a higher air pressure than the surrounding environment to keep pathogens out, are coupled with highly filtered air and water. All personnel are required to wear full personal protective equipment. We typically have anywhere from two to 15 SCID pigs and breeding animals at a given time. (Our breeding animals do not have SCID, but they are genetic carriers of the mutation, so their offspring may have SCID.)
As with any animal research, ethical considerations are always front and center. All our protocols are approved by Iowa State University's Institutional Animal Care and Use Committee and are in accordance with The National Institutes of Health's Guide for the Care and Use of Laboratory Animals.
Every day, twice a day, our pigs are checked by expert caretakers who monitor their health status and provide engagement. We have veterinarians on call. If any pigs fall ill, and drug or antibiotic intervention does not improve their condition, the animals are humanely euthanized.
Our goal is to continue optimizing our humanized SCID pigs so they can be more readily available for stem cell therapy testing, as well as research in other areas, including cancer. We hope the development of the SCID pig model will pave the way for advancements in therapeutic testing, with the long-term goal of improving human patient outcomes.

Satellite imagery can help better predict volcanic eruptions by monitoring changes in surface temperature near volcanoes.
- A recent study used data collected by NASA satellites to conduct a statistical analysis of surface temperatures near volcanoes that erupted from 2002 to 2019.
- The results showed that surface temperatures near volcanoes gradually increased in the months and years prior to eruptions.
- The method was able to detect potential eruptions that were not anticipated by other volcano monitoring methods, such as eruptions in Japan in 2014 and Chile in 2015.
How can modern technology help warn us of impending volcanic eruptions?
One promising answer may lie in satellite imagery. In a recent study published in Nature Geoscience, researchers used infrared data collected by NASA satellites to study the conditions near volcanoes in the months and years before they erupted.
The results revealed a pattern: Prior to eruptions, an unusually large amount of heat had been escaping through soil near volcanoes. This diffusion of subterranean heat — which is a byproduct of "large-scale thermal unrest" — could potentially represent a warning sign of future eruptions.
Conceptual model of large-scale thermal unrestCredit: Girona et al.
For the study, the researchers conducted a statistical analysis of changes in surface temperature near volcanoes, using data collected over 16.5 years by NASA's Terra and Aqua satellites. The results showed that eruptions tended to occur around the time when surface temperatures near the volcanoes peaked.
Eruptions were preceded by "subtle but significant long-term (years), large-scale (tens of square kilometres) increases in their radiant heat flux (up to ~1 °C in median radiant temperature)," the researchers wrote. After eruptions, surface temperatures reliably decreased, though the cool-down period took longer for bigger eruptions.
"Volcanoes can experience thermal unrest for several years before eruption," the researchers wrote. "This thermal unrest is dominated by a large-scale phenomenon operating over extensive areas of volcanic edifices, can be an early indicator of volcanic reactivation, can increase prior to different types of eruption and can be tracked through a statistical analysis of little-processed (that is, radiance or radiant temperature) satellite-based remote sensing data with high temporal resolution."

Although using satellites to monitor thermal unrest wouldn't enable scientists to make hyper-specific eruption predictions (like predicting the exact day), it could significantly improve prediction efforts. Seismologists and volcanologists currently use a range of techniques to forecast eruptions, including monitoring for gas emissions, ground deformation, and changes to nearby water channels, to name a few.
Still, none of these techniques have proven completely reliable, both because of the science and the practical barriers (e.g. funding) standing in the way of large-scale monitoring. In 2014, for example, Japan's Mount Ontake suddenly erupted, killing 63 people. It was the nation's deadliest eruption in nearly a century.
In the study, the researchers found that surface temperatures near Mount Ontake had been increasing in the two years prior to the eruption. To date, no other monitoring method has detected "well-defined" warning signs for the 2014 disaster, the researchers noted.
The researchers hope satellite-based infrared monitoring techniques, combined with existing methods, can improve prediction efforts for volcanic eruptions. Volcanic eruptions have killed about 2,000 people since 2000.
"Our findings can open new horizons to better constrain magma–hydrothermal interaction processes, especially when integrated with other datasets, allowing us to explore the thermal budget of volcanoes and anticipate eruptions that are very difficult to forecast through other geophysical/geochemical methods."
