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.

Feds say Cisco likely failed to protect pro-Palestinian workers from harassment
(JTA) — Cisco Systems likely violated the civil rights of Palestinian, Arab and Muslim employees, a federal agency has found, after employees were subjected to harassing messages — some of them posted by employees in an internal forum called the Connected Jewish Network.
The U.S. Equal Employment Opportunity Commission determined in June that there was “reasonable cause to believe” Cisco subjected the employees to a hostile work environment based on their national origin, religion or association in violation of Title VII of the Civil Rights Act of 1964.
The determination follows on media reports and an EEOC probe into an ugly climate at the tech company following the Oct. 7, 2023, deadly attacks by Hamas on southern Israel. Pro-Palestinian employees called on the company to end its business dealings with Israel, while Jewish employees said the company had failed to protect them from harassment by pro-Palestinian employees.
The EEOC case, however, turned in part on messages shared in the internal Connected Jewish Network forum. A complaint filed by Legal Aid at Work, which represented the Muslim and pro-Palestinian employees, said employees on the Jewish forum had “repeatedly glorified violence, joked about sending people to their deaths” and “labeled Palestinians, Arabs, and Muslims as murderous, violent, terrorists.”
“This is a massive multinational corporation with all the resources in the world and they couldn’t get it right,” Christopher Ho, a director at Legal Aid at Work, told the Guardian, which reported on the EEOC finding last month. “Thankfully the EEOC did.”
Ho said Cisco had “at best failed to take their harassment seriously” and through its inaction had sent “the implicit message that its pro-Palestinian employees were unworthy of protection.”
The letter is not a binding ruling, and both sides said the EEOC has indicated it will not sue. The finding could nonetheless strengthen employees’ cases if they pursue their own lawsuits. The employees are considering collective and individual litigation, according to media reports.
The case examines the period after a group of mostly Palestinian, Arab and Muslim employees called Bridge to Humanity circulated an open letter urging Cisco to end its business dealings with the Israeli military. More than 1,700 employees signed the letter. The employees said they were subsequently subjected to racist and Islamophobic harassment.
In August 2024, employees — including some concerned Jewish employees — filed a 76-page ethics complaint accusing more than a dozen colleagues of creating a hostile work environment through posts on the Connected Jewish Network, which was visible to all company employees, according to the Guardian.
The episode was not one-sided. Wired magazine, in a 2024 investigation into the dispute, reported that some Jewish Cisco employees also believed the company had failed to protect them from harassment by pro-Palestinian employees. One former employee told the magazine that Cisco leadership could have done more to “reduce the mess across the board.”
Legal Aid at Work believes this is the first EEOC finding against a major tech company involving discrimination against workers engaged in pro-Palestinian advocacy. Since the Oct. 7 attacks, the EEOC has made combating workplace antisemitism a major policy and enforcement priority, with scrutiny on academia and the private sector increasing under the Trump administration.
Cisco has disputed the EEOC’s determination, saying it had “thoroughly investigated all concerns and took appropriate action.” The company previously said it had removed some comments, issued discipline warnings and provided coaching to multiple employees.

Mahmoud Khalil sues Columbia University citing ‘hostile environment’ for pro-Palestinian students
Mahmoud Khalil, the Palestinian Columbia University alum who was detained by the Trump administration last year, is suing his alma mater along with an Israeli dean of the school he attended for facilitating a “hostile environment” for pro-Palestinian students.
Khalil became a national symbol of the campus pro-Palestinian protest movement when he was detained in March 2025 after the government accused him of being aligned with terrorists. On Monday, he filed a civil rights lawsuit in federal court accusing the school of engaging in months-long “deliberate indifference” toward the harassment of pro-Palestinian students on campus, including at the hands of right-wing pro-Israel groups.
He contends that Columbia’s alleged indifference ultimately helped to lead to his 104-day detention by federal immigration authorities, during which he missed the birth of his first child, before being released after a federal judge ruled his detainment was likely unconstitutional. He is joined in the suit by members of the School of International and Public Affairs Palestine Working Group, a pro-Palestinian student group on campus.
“Columbia laid the groundwork for my targeting by the Trump administration through its deliberate indifference and discrimination aimed at intimidating Palestinian students,” Khalil told reporters at a press conference in New York on Monday.

In addition to the university, the suit also names Keren Yarhi-Milo, the dean of the Columbia School of International and Public Affairs, who is Israeli-American, as a defendant. The complaint says that Yahi-Milo had unfairly accused Khalil, while a student in the school, of antisemitism and harassment.
In a statement to the Jewish Telegraphic Agency, Columbia representatives defended Yarhi-Milo in general terms.
“Throughout her time at Columbia and during her service as dean, Dean Yarhi-Milo has worked with and supported students of all backgrounds, including our Palestinian, Arab, and Muslim students,” the statement reads. “The University is grateful for her tireless efforts on behalf of our students and her commitment to a campus free of discrimination and harassment.”
Columbia representatives declined to comment further on the lawsuit but said that “creating a campus environment where every member of our community feels welcome, supported, and safe is fundamental to who we are as a university. It is also a responsibility we take seriously.”
A leading figure of the encampment movement that began at Columbia before spreading to schools across the country, Khalil was the first pro-Palestinian student protest leader to be detained by the Trump administration and spent months in an immigrant detention center despite holding a green card.
In the months since a federal judge ordered his release, Khalil has filed a number of lawsuits, including against pro-Israel groups that he said “conspired” with the government to target him. He has also sued Columbia before, for disclosing student records as part of a congressional investigation.
Khalil’s latest lawsuit against Columbia claims the school violated Title VI protections for him and his fellow plaintiffs based on their ethnic identity, national origin or “affiliation with Palestine.” The lawsuit invokes the same federal civil rights law that Jewish and Israeli students have used in discrimination claims against universities, some of which have resulted in settlements.
Columbia itself signed a controversial agreement with the Trump administration last year to resolve federal civil rights investigations, paying $221 million and agreeing to a number of concessions in order to free up hundreds of millions in federal funding. During his press conference Monday, Khalil called such settlements “disgraceful.”
The suit notes that, as a student, Khalil called Yarhi-Milo “genocidal” in a message to fellow students. The suit then describes a subsequent internal university investigation into Khalil as “unfounded and retaliatory,” and claims the school “repeatedly launched meritless allegations of antisemitism against Mr. Khalil” prior to his federal detention.
During the press conference, Khalil accused Yahi-Milo of being someone who “weaponizes her identity to shield herself from legitimate concerns and criticism.” Khalil added, “Her priority has never been her students, me and my fellow students here. Her priority has always been Israel.”
The lawsuit’s examples of indifference include a claim that Columbia failed to intervene when a right-wing group, Accuracy in Media, labeled some of the members of Palestine Working Group as “Columbia’s Leading Antisemites” in messages on the side of trucks driven near campus for months after the Oct. 7, 2023, Hamas attacks. The group had targeted pro-Palestinian students in a similar fashion at several campuses.
Joseph Howley, a classics professor at Columbia who is Jewish, spoke at the press conference in support of Khalil, whom he called a friend. “We all see how the university’s anti-Palestinian racism has directly endangered its students,” said Howley, who wore a Jews for Racial and Economic Justice hat and a “Not In Our Name” shirt. “I won’t be wasting any more time on town halls or listening sessions or imagining anything.”
In a statement to JTA, Accuracy in Media president Adam Guillette said his group “uses publicly available information, and we are steadfastly opposed to doxxing. We pledge to continue delivering accountability to pro-Hamas radicals across the country.”

Ed Sheeran says it wasn’t his call to drop Macklemore over ‘Free Palestine’ remarks
(JTA) —
Pop superstar Ed Sheeran said he wasn’t behind his tour’s recent decision to drop opening act Macklemore following the rapper’s recent pro-Palestinian remarks at a stadium show.
“I am not complicit,” Sheeran wrote in a statement on Instagram Tuesday, saying that Macklemore leaving the tour “was the promoter’s decision, it was not mine.” These were his first public words on the controversy that has gathered steam over the last 24 hours.
Hours after Sheeran’s comments, three of his other supporting acts announced they would be leaving his tour. All three acts — Aaron Rowe, Beoga and Finneas — posted pro-Palestinian solidarity statements to Instagram in their announcements.
Sheeran’s own note added, “I am appalled by the conflict between Israel and Palestine.” The British singer-songwriter wrote that he had been “involved in direct talks” between Robert Kraft and various promoters “to try and find a mutual resolution for all.”
Kraft, the Jewish and pro-Israel billionaire who owns one of the stadiums where Sheeran and Macklemore had been scheduled to play, said on Monday that he had told Sheeran’s team that Macklemore wouldn’t be allowed to perform there.
In his own statement to JTA, Kraft had said that Macklemore’s recent performance at New Jersey’s MetLife stadium, at which the rapper accused Israel of genocide and broadcast images from Gaza, “has been deeply offensive and hurtful to the Jewish community.” Pop star Pink, who is Jewish, also criticized Macklemore following the performance.
Sheeran didn’t mention Jews in his statement, but noted, “I have always used my platform and music to bring people from all backgrounds and cultures together and this won’t ever change.”

He also had some veiled criticism of his tourmate’s methods. “Those who come to my shows do not expect a political forum,” Sheeran wrote. “I respect Macklemore’s strength of purpose to stand up for what he believes. However, there is room for multiple approaches to the same end: peace… If we only focus on shouting the loudest, nothing will ever change.”
The other acts who announced they were leaving Sheeran’s tour didn’t agree. Some had strong words for Kraft and Zionism.
“As Irish people we know all too well about genocide, forced famine and violent occupation,” Rowe wrote in his own statement. “I cannot stand by and allow billionaires to use their position of power to silence the rightful voices of those who speak up against Israeli genocide and who highlight the savage murder of children.”
“It’s important that everyone knows that the real enemy is the zionist lobby,” Beoga, also an Irish act, wrote in the band’s own statement. “Research how much Robert Kraft has done to fight the BDS movement. That will give you a sense of what we’ve all been up against.”
In a shorter statement, Finneas said, “Artists must not be silenced when they speak up for the oppressed.” He added, “I stand with Palestine and its people.”
The Israeli-American Council, which organized a boycott against Macklemore following his New Jersey show, criticized Sheeran from the other direction in a new statement to the Jewish Telegraphic Agency.
“It’s time to take responsibility for giving a stage to antisemitic messaging,” the IAC said, of Sheeran. “This isn’t just ‘criticism of Israel.’ It’s a message that crosses the line between legitimate political criticism and antisemitism. This is Ed Sheeran’s stage, it’s the tour that carries his name — and so the responsibility for what happens on it is his too.”
