A German town built a granary atop its Jewish cemetery. Now the bones are yielding insights about Ashkenazi DNA.
BERLIN (JTA) – The city of Erfurt in central Germany is home to an impeccably restored medieval synagogue made possible because local Jews had been expelled long before the Nazis began their campaign to destroy Jewish sites.
Now, Erfurt’s long-hidden Jewish past is again offering new insights — this time about the genetic history of Ashkenazi Jews.
Human remains from a medieval Jewish cemetery in Erfurt have allowed what researchers say is the largest ancient Jewish DNA study to date. Conducted without disinterring any remains, in keeping with Jewish law, the study published Wednesday in the scientific journal Cell found that Erfurt’s medieval Jewish community was more genetically diverse than their modern-day cousins, and carried many of the same Jewish genetic diseases — such as Tay Sachs and cystic fibrosis — that affect Ashkenazi Jews today.
“There have been many previous DNA studies, but not of Jews,” said geneticist Shai Carmi, a professor at the Hebrew University of Jerusalem, whose search for study material led him to an archaeological dig at the Jewish cemetery in Erfurt. He and his collaborators were able to analyze DNA of 33 individuals who died between 1270 and 1400, using teeth they found there.
The study follows a similar analysis revealed in August by researchers in England, who studied the DNA from skeletons found at the bottom of a medieval well and concluded that the remains were likely of victims of an antisemitic massacre in 1190. Analysis of six individuals prior to their identification as Jewish revealed that Ashkenazi Jews developed a unique genetic variation centuries earlier than realized.
The Erfurt analysis also includes samples from before the epidemic of Black Death that was until recently understood to have created the genetic “bottleneck” that created the genetic markers common among Ashkenazi Jews today.
Erfurt’s Jewish settlement existed from the 11th to 15th century, with a brief gap following a 1349 massacre perpetrated after the Jews were falsely blamed for causing the bubonic plague. Surviving Jews returned there, but after all Jews were expelled once and for all in 1454, the city built a granary on top of the Jewish cemetery.

In 2013, the city approved the repurposing of the unused granary into a parking lot. Because it was an historic site, a rescue excavation was initiated, overseen for the State of Thuringia by German archaeologist Karin Sczech.
Meanwhile, Carmi had been looking for Jewish cemeteries anywhere in the world “where we could analyze remains already excavated,” he told JTA in a telephone interview from Jerusalem. “I consulted historians and eventually reached the archeologist in Erfurt.” Fortunately, he said, “they still hadn’t reburied the remains.”
He approached Sczech, who later became a co-author of the new study. In 2018, with a supportive judgment from Rabbi Ze’ev Litke — an Israeli expert on genetics and Jewish law — and permission from Erfurt’s then-rabbi, Benjamin Kochan, work began to extract and analyze DNA from detached teeth found in the graves. (About 500 Jews live in Erfurt today, most of them having migrated from the former Soviet Union since 1990.)
American geneticist David Reich picked up the teeth and brought them back to the department of human evolutionary biology at Harvard University in Cambridge, Massachusetts, where drilling and DNA extraction took place.
While the skeletons were reburied, the teeth are still stored at the research institutes where they have been analyzed, in case scientists need to retest to verify the result.
The project provides an ethical basis for studies of ancient Jewish DNA, Carmi said. “Of course we couldn’t just go to a cemetery and dig and take out skeletons; this would be prohibited,” he said, referring to Jewish law prohibiting the removal of bones from where someone was buried.
But Litke opined that the study could be done, because the bones already had been disturbed for an unrelated reason. “He recommended using teeth, as the analysis does almost no damage,” Carmi said.
There are many motivations to study Jewish DNA: One can find lost relatives going back a few generations, and answer questions about Jewish origin of partners intending to marry. But the goal of Carmi’s team was “to fill the gaps in our understanding of Ashkenazi Jewish early history.”
There are several non-destructive ways to obtain DNA from human remains, said Carmi, who also works as a consultant to an Israeli firm that helps clients trace their genetic roots.
“You can take an almost microscopic slice of bone and extract DNA in a solution, or put the entire bone in a solution and extract the DNA without drilling, without disturbing the dead. This opens the way to doing studies even without teeth,” he added.
His team found that the Erfurt community appeared to fit into two genetically distinct groups, descending either from Middle Eastern or European populations. This genetic variability no longer exists, Carmi said.
At the same time, Carmi said, the analysis found remarkable continuity in the local community, as well. “One third of the Erfurt individuals descended from one woman through their maternal lines,” he said, adding that evidence suggested that she lived between 1,000 and 2,000 years ago.
In a press statement, geneticist Reich of Harvard said the work “also provides a template for how a co-analysis of modern and ancient DNA data can shed light on the past. Studies like this hold great promise not only for understanding Jewish history, but also that of any population.”
The research team, with more than 30 scientists, included Hebrew University’s Shamam Waldman, a doctoral student in Carmi’s group, who performed most of the data analysis.

Four Seats or No Seats? Why Israel’s Final Polls Disagree Over Amcha Yisrael
Conflicting projections for Ofer Winter’s party illustrate the uncertainty of measuring public support near an electoral threshold.
A Channel 12 poll gives Ofer Winter’s Amcha Yisrael four parliamentary seats.
An i24NEWS survey reaches the same seat total.
Other final polls find that the party does not qualify for representation.
How can surveys conducted close to the same election produce such different results?
The answer lies partly in the difference between measuring a vote share and converting it into parliamentary seats.
A Statistical Boundary
Israel’s electoral threshold is 3.25 percent.
For a party receiving substantially more than that percentage, modest sampling fluctuations may change its expected number of seats without calling its parliamentary presence into question.
For a party whose support lies near 3.25 percent, the same type of fluctuation may change its projected representation from several seats to zero.
This does not necessarily mean the polls are measuring completely different political realities.
They may be producing estimates close to the same threshold but on opposite sides of it.
Sample Size Is Only One Factor
The i24NEWS survey conducted on October 22 included 5,124 adult respondents and reported a sampling error of plus or minus 1.4 percentage points at the 95 percent confidence level.
That is a substantial sample by conventional political polling standards.
But a larger sample does not eliminate every source of uncertainty.
Different pollsters may employ different recruitment methods, weighting systems and procedures for estimating turnout.
They may also differ in how they handle respondents who are undecided or reluctant to state their preferences.
These choices can matter particularly for smaller parties.
The Problem of Turnout
Opinion polls generally estimate voting preferences before actual voting takes place.
Election results reflect the ballots cast by people who participate.
Differences between intended and actual turnout can affect parties in different ways.
Analysts must therefore consider not only how many respondents express support for a party, but also whether the poll’s turnout model accurately reflects the eventual electorate.
Without transparent, comparable information about the methods used by each polling organization, it is difficult to identify which methodological difference is responsible for a particular disagreement.
Reading the Final Surveys
The appropriate interpretation of Amcha Yisrael’s polling is neither that its parliamentary representation is guaranteed nor that exclusion is certain.
The available surveys demonstrate uncertainty around a legally decisive boundary.
The four-seat projections reported by Channel 12 and i24NEWS are meaningful observations.
So are the below-threshold findings published by Channel 13, Maariv and Zman Yisrael.
Each survey is a measurement of electoral intentions under a particular methodology, not a count of actual votes.
For readers following Israel’s election, this makes Amcha Yisrael an instructive case study in how polling uncertainty interacts with electoral law.
The final result will provide the definitive seat allocation. The polls explain why the outcome was difficult to measure in advance.

As Trump betrays Ukraine, it’s beginning to feel a lot like Munich
In Munich on Sept. 30, 1938, the leaders of Britain and France signed an agreement with Adolf Hitler that caved to the Nazi leader’s demand that Germany be given a chunk of Czechoslovakia. Five months later, Hitler ordered the German military to forcibly take the remainder of the neighboring country.
On Oct. 9, 2026, Donald Trump and Vladimir Putin struck a deal allowing Russia to sell diesel fuel to global markets, most importantly to the US. Then Trump waived a package of sanctions on Russia that had been passed by Congress. By replenishing Russia’s war coffers, it is likely more Ukrainians will die because of these twin gifts from America’s president to the warmongering Russian autocrat.
Why is Trump doing this? He seems to be hoping the diesel deal will help him avert disaster in the upcoming midterms. Or maybe there’s more to it than that. Perhaps Trump seriously thinks that this will get him the Nobel Peace Prize by ending the war in Ukraine through helping Putin win it. Perhaps it’s one more scheme to further enrich himself and his family. Or maybe Putin really does have something on Trump.
In any event, it feels like Munich all over again.
There are some remarkable parallels between Czechoslovakia’s predicament in 1938 and Ukraine’s nine decades later: separatists in two vulnerable Central European democracies were encouraged and supported by a neighboring authoritarian regime that sought to seize adjacent territory under the pretext of protecting a minority from oppression.
And at the center of both narratives is betrayal: of Czechoslovakia by Britain and France, and Ukraine by Trump.
In the spring and summer of 1938, Konrad Henlein, leader of the Nazi-allied Sudeten German Party in Czechoslovakia, held secret meetings with Hitler and other Nazi officials. They concocted a plan: Cause so much disorder in the Sudetenland that the Czech government would declare martial law, thus creating an excuse for German troops to march in to protect the ethnic German minority.
Tensions that had long existed along the Czech frontier erupted into gunfire and death in the Sudeten town of Habersbirk on the morning of Sept. 13, 1938. A mob of German separatists hung a swastika banner from a church tower, stormed the police station, kidnapped the wife of a cop, and engaged in gunfights with police officers that lasted hours. Four Czech police officers and four insurgents died. Outbreaks of violence, terror and torture raged along the border for days, backed by Freikorps paramilitary troops who crossed from Germany and by SA and SS men who took part in cross-border sabotage and armed attacks.
The uprising had the desired impact. Just 17 days later — on Sept. 30, 1938 — Britain, France, Italy and Nazi Germany signed the Munich Agreement, yielding to Hitler’s demand that the Sudetenland be ceded to him. After landing at an airport outside London, Prime Minister Neville Chamberlain waved a document in his hand and jubilantly proclaimed:
“The settlement of the Czechoslovak problem which has now been achieved is, in my view, only the prelude to a larger settlement in which all Europe may find peace.”
“I believe it is peace for our time,” Chamberlain said later that day.
But it didn’t take long for Hitler to show he could not be trusted. Hitler’s army marched into Czechoslovakia on March 15, 1939. Germany’s invasion of Poland followed less than six months later, and by 1942 German forces controlled territory spanning from the Atlantic Ocean to deep inside the Soviet Union.
Ethnic Germans’ uprising in Czechoslovakia in 1938 found an echo nine decades later in Ukraine’s Donbas region, where unrest that began with pro-Russia protests in 2014 evolved into the war Russia has been waging on its neighbor for nearly five years.
In the spring of 2014, paramilitary units led by Russian intelligence officers stormed government office buildings in several towns and cities in Donbas, seizing weapons and clashing with police. In a scene reminiscent of the Habersbirk siege of 1938, on April 14, 2014, pro-Russian militants seized the police station in Horlivka, beat up the police chief, and murdered a member of the city council, whose body was found in a river. Similar clashes occurred throughout Donbas.
Two Kremlin-backed pseudo-states soon emerged: the Donetsk People’s Republic and the Luhansk People’s Republic. Russia funneled tanks, artillery, air defense systems and fighters into Donbas, fueling a war between separatists and Ukrainian forces that dragged on for years.
Like Hitler in the Sudetenland, Russia’s de facto occupation of Donbas was not enough for Vladimir Putin. His eyes were on all of Ukraine, and he spent years manufacturing pretexts for the full-scale invasion that began on Feb. 24, 2022.
Trump has been buttering up Putin for more than a decade, starting with his 2015 campaign for president, when he effusively praised the ruthless Russian autocrat’s leadership style. Putin is a “strong leader,” is “far more respected than our president,” meaning the immensely popular Barack Obama, and was someone he “would get along with very well,” Trump said back then.
Trump’s admiration for Putin took on ominous tones after becoming president. During a press conference after the two leaders’ 2018 Helsinki summit, Trump questioned intelligence findings on Russian election interference and said he believed Putin’s denial. “I don’t see any reason it would be Russia,” Trump told reporters, with the Russian strongman standing at his side.
After Russia’s invasion of Ukraine in 2022, during Biden’s presidency, Trump called it “a pretty smart move,” praised Putin as a “genius,” and also said it wouldn’t have happened if Trump was still president, remarks that were amplified by Russian state media.
During Trump’s second term, his buddy-buddy relationship with Putin has turned into a virtual strategic alliance, as the American president repeatedly makes moves and statements that seem designed to please the Russian autocrat. There are Trump’s threats to abandon NATO, his humiliation of Ukraine President Volodymyr Zelensky during a February 2025 meeting inside the Oval Office, and most recently Trump’s demand that Ukraine cease its drone attacks on Russian oil refineries, his call for Zelensky’s ouster, and envoy Steve Witkoff thanking Putin for being a “humanitarian.”
Putin has proposed a summit between himself, Trump, and Chinese leader Xi Jinping to discuss ending the war in Ukraine. It’s notable that Ukraine has not been invited. This is also what happened in Munich nine decades ago, when Czech delegates were excluded from the room, and others decided Czechoslovakia’s fate.
Last October, aboard Air Force One, Trump told reporters the Donbas region should be “cut up,” leaving most of it in Russian hands.
“Let it be cut the way it is,” he said. “They can negotiate something later on down the line.”
It seems the fate Trump envisions for Ukraine is similar to the one Hitler envisioned for Czechoslovakia. It would be naïve to think that Putin’s expansionist ambitions would stop there.

A Chabad Jew was stabbed in NYC. He returned the next day to continue wrapping tefillin.
(JTA) — Less than 24 hours after he was stabbed in midtown Manhattan, Yosef, a Chabad-Lubavitch man from Crown Heights, was back on the same street where he’d been assaulted, popping into Diamond District businesses as usual to help employees wrap tefillin.
Yosef, 26, who did not share his last name to maintain his privacy, told the Jewish Telegraphic Agency that he was back on 47th Street on Thursday afternoon, the day after the stabbing, without missing a beat in his Monday-through-Thursday rounds even as police investigate the incident as a possible hate crime.
A number of the people he visited pieced together that the widely circulated footage of a man being stabbed the previous night was of him.
“They were in shock. They were obviously scared for me,” said Yosef, who has been wrapping tefillin and distributing Shabbat candles to Jewish Diamond District employees for about three years. He started that routine when his father, a Chabad Jew who works in the jewelry business, realized he needed his son’s help to handle the demand for those acts. Yosef told Chabad.org that he was “still shaken” by the attack a day later.
Still, he told JTA, “We can’t allow some hate to stop us.”
Yosef said he felt it was important to communicate that message because “we need more mitzvahs in the world, we need more light in the world.”
Yosef was taken to Bellevue Hospital on Wednesday evening around 6 p.m., where medical staff assessed that he had no internal bleeding and would not need stitches. No arrests have been made, but the assailant has been described as a woman in her 40s.
The attack has renewed concerns about security that have faced Chabad adherents and institutions, which often host public events and maintain a visible street presence. But the threat didn’t diminish their presence in midtown Manhattan on Friday.
Multiple Chabad men stood under a bright yellow tent on the sidewalk wrapping tefillin for a steady stream of workers in the heavily Jewish Diamond District.
“The Rebbe says that the way to defeat darkness is only through the addition of light,” said Shmuel Cohen, who was handing out small photographs of the movement’s late leader, the Lubavitcher Rebbe Menachem Mendel Schneerson.
Cohen told JTA that he had not heard about the attack that took place just down the block two days earlier, though his partner under the sidewalk tent had. Cohen said that the best way to respond is through “the observance of Torah and mitzvot without being ashamed of our Judaism but presenting it to everyone.”
Also on Friday, Chabad officials met with New York Police Department representatives for their annual meeting about security ahead of Chabad’s international conference in Crown Heights, the Brooklyn neighborhood where the movement is headquartered. The conference begins on Nov. 5.
Chabad has been targeted in multiple high-profile attacks in the past year, including the deadly Bondi Beach shooting in Australia in December. The following month, a man rammed a car into the doors of the Chabad-Lubavitch headquarters in Brooklyn, raising further questions over how the movement should balance its commitment to making its events accessible with security.
Meanwhile, Jews have been targeted in more than half of hate crimes committed in New York City in 2026, despite making up about 12% of the city’s population.
“Security is our top priority. Our goal is to provide an environment where every participant feels safe and can fully experience the purpose and spirit of the gathering,” said Rabbi Mendy Kotlarsky, a top organizer of the upcoming conference.
In the wake of the attack, Yosef said he is not concerned about going out in public as a visibly Jewish person and doesn’t plan to change how he approaches the world.
“I was wearing the same clothes on Tuesday and Wednesday and Thursday,” he said. “I didn’t change my routine.”
