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.

New ADL Campus Antisemitism Report Card Shows Some Improvement on Addressing Hostile Climate

The Anti-Defamation League (ADL) has released a new annual “Campus Antisemitism Report Card,” in which its researchers assigned grades to major US colleges and universities based on how the institutions responded to the issue in accordance with civil rights laws and their own professed values.
Released on Monday, the report rewarded some elite colleges previously accused of ignoring antisemitism with letter grades considerably above what they earned in past academic years. Most notably, no Ivy League institution merited an “F” this year, while Columbia University, Princeton University, and Yale University all improved on last year’s close to failing “D” grade by earning a “C.”
A “C” grade, a mark again given to Harvard University and Cornell University in this year’s report, indicates lingering areas of inertia in performance. Pomona College, Northwestern University, Swarthmore College, and the University of Chicago were assigned a “C” too, indicating that elite higher education across the country remains a problematic space for Jewish youth.
Meanwhile, four colleges, including Evergreen State College, Scripps College, California State University, Los Angeles, and The New School in New York City received an “F,” the only institutions in the cohort to fail the ADL’s assessment.
“The data confirms what we’ve said from the start: maintaining a safe campus climate is a matter of will,” ADL chief executive officer Jonathan Greenblatt said in a statement. “Universities that have taken a comprehensive approach — reviewing policies, clarifying expectations, and strengthening enforcement — are seeing meaningful progress. Some of the strongest gains are coming from institutions that have engaged deeply with our recommendations and translated them into lasting institutional practice, rather than symbolic commitments.”
The 2025-2026 academic year has seen a continuation of the barrage of antisemitic incidents that led Jewish community advocates to describe the issue as a “problem,” with anti-Zionist activists continuing to disrupt events, harass Jewish students, and stage demonstrations related to how Israel conducts its foreign policy and manages its conflict with the Palestinians.
In October, for example, masked pro-Hamas activists breached an event held at Pomona College in California to commemorate the victims of the Oct. 7, 2023, massacre in which Hamas-led Palestinian terrorists raped, murdered, and abducted women, children, and men during their rampage across southern Israel.
Footage of the act circulated on social media showed the group attempting to raid the room while screaming expletives and pro-Hamas dogma. They ultimately failed due to the prompt response of the Claremont Colleges Jewish chaplain and other attendees who formed a barrier in front of the door to repel them, a defense they mounted on their own as campus security personnel did nothing to stop the disturbance, according to video of the incident and witnesses who spoke to The Claremont Independent.
Following the incident, an anonymous group claimed credit for storming the event in a disturbing open letter.
“Satan dared not look us in the eyes,” said the note, which the group released on social media, while attacking event guests and Oct. 7 survivor Yoni Viloga. Appearing to threaten murder, the group added, “We let that coward know he and his fascists settler ideology are not welcome here nor anywhere. zionism is a death cult that must be dealt with accordingly [sic].”
In January, a sophomore and right-wing social media influencer at the University of Miami verbally attacked a Jewish student group, leading the school to defend free speech while saying that “lines can be crossed” in response.
“Christianity, which says love everyone, meanwhile your Bible says eating someone who is a non-Jew is like eating with an animal. That’s what the Talmud says,” Kaylee Mahony yelled at members of Students Supporting Israel (SSI) who had a table at a campus fair. She added, “They think that if you are not a Jew you are an animal. That’s the Talmud. That’s the Talmud.”
In December, an unidentified perpetrator twice vandalized the Chabad Jewish Center at Michigan State University (MSU) during the Hanukkah holiday. According to local reports, the vandal hurled rocks at and defaced the building’s entrance, shattering its glazing. Video footage of the suspect’s second trip to the Chabad center shows the vandal graffitiing the swastika, the emblem of Nazi Germany, next to which he spray-painted a message that said, “He’s back.”
That was not the first antisemitic incident to target a Jewish cultural center in the state of Michigan this academic year. In October, a man trespassed the grounds of the Jewish Resource Center, which serves University of Michigan students, and kicked its door while howling antisemitic statements.
The campus antisemitism crisis has changed the college experience for American Jewish students, affecting how they live, socialize, and perceive themselves as Jews, according to survey results released in February by the American Jewish Committee (AJC) in partnership with Hillel International.
A striking 42 percent of Jewish students reported experiencing antisemitism during their time on campus, and of that group, 55 percent said they felt that being Jewish at a campus event threatened their safety. The survey also found that 34 percent of Jewish students avoid being detected as Jews, hiding their Jewish identity due to fear of antisemitism. Meanwhile, 38 percent of Jewish students said they decline to utter pro-Israel viewpoints on campus, including in class, for fear of being targeted by anti-Zionists. The rate of self-censorship is significantly higher for Jewish students who have already been subjected to antisemitism, registering at 68 percent.
Higher education institutions have an added incentive to address antisemitism, as the reelection of US President Donald Trump brought to Washington, DC a chief executive who went on to fulfill his promise to tax the endowments of those that do not.
Shortly after taking office, Trump issued an executive order which directed the federal government to employ “all appropriate legal tools to prosecute, remove, or otherwise … hold to account perpetrators of unlawful antisemitic harassment and violence.” Additionally, the order initiated a full review of the explosion of campus antisemitism on US colleges across the country after Oct. 7, 2023, a convulsive moment in American history to which the Biden administration struggled to respond during the final year and a half of its tenure.
“This failure is unacceptable,” Trump said. “It shall be the policy of the United States to combat antisemitism vigorously, using all appropriate legal tools to prosecute, remove, or otherwise hold to account the perpetrators of unlawful antisemitic harassment and violence.”

Ted Cruz, Tom Cotton Call Out Right-Wing Anti-Israel Influencers During Antisemitism Conference

Two prominent US Republican senators issued stark warnings this week about what they described as a growing strain of antisemitism within parts of the conservative media ecosystem, using a Washington symposium hosted by the Republican Jewish Coalition and National Review to call out influential right-wing commentators and urge fellow Republicans to confront the problem directly.
Speaking at Tuesday’s event, Sen. Ted Cruz (R-TX) sharply criticized conservative media personality Tucker Carlson, calling him “the single most dangerous demagogue in this country” and accusing him of amplifying extremist rhetoric and historical revisionism to a large online audience.
Cruz argued that antisemitic ideas have increasingly surfaced in segments of right-wing media over the past year and a half, particularly among younger audiences consuming political content online. While Republican leaders have often been quick to condemn openly extremist figures, Cruz said the party has been more reluctant to challenge more mainstream influencers who command massive followings.
“This is the beginning of a battle where our nation, our beliefs, our Constitution, the principles that built America, are under assault. And we need to gird ourselves for battle and defeat this garbage,” Cruz said to the audience.
Cruz warned that commentators with mainstream visibility can normalize rhetoric once confined to the political margins.
“I want us to be winning, but I’m not sure it is accurate as a descriptive manner that we are winning right now,” Cruz said.
Sen. Tom Cotton (R-AK) delivered a similar message during the symposium, criticizing unnamed right-wing “influencers” who he said were smuggling antisemitism into the conservative movement and promoting ideas incompatible with conservative principles. Cotton dismissed their influence as inflated and said their rhetoric echoed arguments more commonly associated with critics of Israel on the political left.
“I do not agree that I share a political movement or a political party with anyone who traffics antisemitism,” he said.
The remarks highlight an emerging divide within the Republican Party and the broader conservative movement over foreign policy, Israel, and the boundaries of acceptable political discourse. While establishment Republicans have long maintained strong support for Israel, a newer wave of populist commentators has increasingly questioned US involvement in Middle East conflicts and criticized Israel more aggressively.
Some of those commentators have drawn accusations from critics, including fellow conservatives, that their rhetoric veers into antisemitic tropes or conspiratorial narratives about Jewish influence.
Carlson has sparked backlash among conservatives over his consistent pattern of condemning Israel and platforming individuals who peddle antisemitic narratives. He has falsely suggested that Israel, the world’s lone Jewish state, oppresses and persecutes Christians.
During an interview with controversial podcaster Darryl Cooper, Carlson did not push back after Cooper argued that the US was on the “wrong side” of World War II and that former British Prime Minister Winston Churchill, not Adolph Hitler, “was the chief villain” of the conflict. Cooper also suggested that the slaughter of six million Jews in concentration camps was “humane” because the Nazis did not have food to feed the “prisoners of war.”
Carlson also conducted a friendly interview with Nick Fuentes, an avowed antisemite and Holocaust denier, that was released last year. During the conversation, both men rebuked Israel and Zionism, with Carlson lambasting Christian Zionism as an affront to the values of Christianity.
In the two years following the Hamas-led Oct. 7, 2023, attacks in Israel, conservative commentators have found themselves increasingly split over Israel and foreign policy. Beyond Carlson, popular conservatives such as Steve Bannon and Megyn Kelly have also ramped up criticisms of Israel, oftentimes arguing that the Jewish state has embroiled the United States in unnecessary wars on their behalf.
Further, recent polling reveals the existence of a sizable antisemitic contingent within the GOP base, heavily concentrated among the younger cohorts which more frequently engage with content of online pundits. For example, the Manhattan Institute, a prominent US-based think tank, released a survey poll in December examining the evolving makeup of the Republican Party (GOP) and its current attitudes toward Israel and Jewish Americans.
According to the results, newer entrants to the GOP are more likely to be antisemitic.
“Anti-Jewish Republicans are typically younger, disproportionately male, more likely to be college-educated, and significantly more likely to be New Entrant Republicans,” the survey found. “They are also more racially diverse. Consistent church attendance is one of the strongest predictors of rejecting these attitudes; infrequent church attendance is, all else equal, one of the strongest predictors of falling into this segment.”
The data also showed that older GOP voters are much more supportive of Israel and less likely to express antisemitic views than their younger cohorts.
According to the data, 25 percent of GOP voters under 50 openly express antisemitic views as opposed to just 4 percent over the age of 50.
Startlingly, a substantial amount, 37 percent, of GOP voters indicate belief in Holocaust denialism. These figures are more pronounced among young men under 50, with a majority, 54 percent, agreeing that the Holocaust “was greatly exaggerated or did not happen as historians describe.” Among men over 50, 41 percent agree with the sentiment.

Israel Becomes World’s 7th Largest Arms Exporter

Israel has become the world’s seventh-largest arms exporter, steadily increasing its share of global weapons sales even amid a multi-front war and mounting international criticism, according to a new report.
On Monday, the Swedish-based Stockholm International Peace Research Institute (SIPRI) released its latest report on global arms exports, analyzing trends from the last five years (2021–2025) and comparing them with the previous period (2016–2020).
For the first time, Israel has surpassed Great Britain to become the world’s seventh-largest arms exporter, with its share of global weapons sales rising to 4.4 percent in 2021–2025, up from 3.1 percent in the previous period.
“Despite conducting the war in Gaza and attacks in Iran, Lebanon, Qatar, Syria, and Yemen, Israel still managed to increase its share of global arms exports,” Zain Hussain, researcher at SIPRI’s Arms Transfers Program, said in a statement.
According to the newly released report, Israel also ranked as the 14th-largest arms importer in the world, acquiring most of its weapons from the United States (68 percent) and Germany (31 percent), with a small share from Italy (1 percent), showing that arms embargoes and international criticism have done little to slow its defense trade.
Overall, the total volume of the global arms trade rose by 9.2 percent in the last five years compared to the previous period, with European nations more than tripling their weapons imports to become the world’s largest arms-importing region amid rising regional tensions with Russia and escalating conflict in the Middle East.
The US continued to be the world’s largest arms exporter in 2021–2025, holding a 42 percent share of global sales, followed by France (9.8 percent), Russia (6.8 percent), Germany (5.7 percent), China (5.6 percent), Italy (5.1 percent), and Israel.
Among Middle Eastern countries, Saudi Arabia leads as the top purchaser of American arms with 12 percent of sales, followed by Qatar and Kuwait, while Israel ranks 12th globally, receiving just 3.1 percent of all US arms exports
SIPRI’s latest report comes as the Jewish state faces growing international pressure, with European states among the most vocally critical and threatening arms embargoes over Israel’s defensive war against the Palestinian terrorist group Hamas in Gaza and its military campaign against Iran.
Despite these threats, Israel’s arms exports have continued to grow, solidifying its position as a leading player in the global weapons market.
For example, the UK and Germany have pressed ahead with arms purchases from Israel despite repeated threats and public warnings to suspend defense trade, signaling the limits of international pressure.
Israel now supplies 8.2 percent of British arms purchases, second only to the US, which accounts for 85 percent.
In Israel’s biggest-ever arms export deal, Germany recently acquired the Arrow missile defense system, marking the largest weapons sale in the country’s history.
According to the SIPRI report, Israel’s growth in global arms exports was driven primarily by international sales of air defense systems, even as the country faced heavy domestic demand for weapons amid a multi-front war.
Overall, Israel sold arms to 23 European countries (41 percent of its total exports), 10 Asian countries (40 percent), five in North and Latin America (8.6 percent), and seven African nations.
