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.

U.S. Senate candidate from Michigan calls Israeli government ‘evil’ like Hamas
Abdul El-Sayed, a U.S. Senate candidate from Michigan, said in an interview aired Sunday that the Israeli government is as “evil” as Hamas, sharpening his criticism of Israel in the closely-watched Democratic primary.
“Killing tens of thousands of people makes you pretty damn evil,” El-Sayed told CNN congressional reporter Manu Raja on the network’s Inside Politics program. “It’s not how evil is this one versus that one — Hamas: Evil, Israeli government: Evil. We can say both.”
El-Sayed, 41, is a physician and the son of Egyptian immigrants. He is seeking to channel the energy of the 2024 Uncommitted movement, which protested the Biden administration’s support for Israel in the war against Hamas in Gaza. He is also hoping to build on the surprise success of the New York City mayoral campaign of Zohran Mamdani in taking on the Democratic establishment.
He is locked in a dead heat with state Sen. Mallory McMorrow and Rep. Haley Stevens. The primary is set for Aug. 4.
Earlier this month, El-Sayed faced backlash for appearing alongside streamer Hasan Piker, who has been accused of antisemitic rhetoric — including saying that Hamas “is a thousand times better” than Israel. McMorrow, who is married to a Jewish man, and Stevens, who is closely aligned with AIPAC, have both criticized El-Sayed.
In the CNN interview, El-Sayed defended his decision to campaign with Piker, framing it as an effort to reach voters who feel alienated from traditional politics. “My understanding of America is, it’s a place where we have freedom of speech,” he said.
#MISen Abdul El-Sayed on CNN Inside Politics: @mkraju: You said Israeli government is evil. Do you think they’re just as evil as Hamas?

The Michigan Senate race is shaping up as one of the starkest tests of the Democratic coalition and how the party navigates policy towards Israel in Congress amid the wars in Gaza and Iran. The state is home to the largest concentration of Arab Americans in the United States.
Last week, 40 Senate Democrats voted to block $295 million for the transfer of bulldozers, used by the Israeli military to demolish homes in the West Bank and Gaza; 36 of them also supported a measure to block the sale of 1,000-pound bombs to the Jewish state. It shattered a previous high of 27 Democrats who backed a similar pair of resolutions of disapproval to block some weapons transfers last year.
Sen. Elissa Slotkin of Michigan, who is Jewish, was among those who voted for the measures. In remarks as they announced their votes, Democrats highlighted their opposition to the Israeli government’s policies in the occupied West Bank, the humanitarian situation in Gaza and the war with Iran.

NYC Mayor Mamdani Unveils Major Tax Hike on Unoccupied Luxury Real Estate

i24 News – NYC Mayor Zohran Mamdani has officially introduced a controversial new tax targeting secondary residences valued at over $5 million.
The measure, designed to tap into the city’s vast concentration of unoccupied luxury wealth, is projected to generate roughly $500 million annually for the municipal budget.
“This tax is specifically aimed at the ultra-rich,” Mamdani stated, highlighting high-profile examples such as Ken Griffin’s $238 million Midtown penthouse and Alexander Varshavsky’s $20.5 million Columbus Circle residence.
While the city has yet to finalize specific evaluation criteria or the methods for distinguishing primary from secondary homes, the proposal has already become a flashpoint for economic debate.
The move has drawn sharp condemnation from billionaire investor Bill Ackman, who argued that the policy is fundamentally flawed.
Ackman contended that owners of luxury secondary residences contribute significant capital to the local economy without utilizing costly municipal services. He warned that the tax would likely trigger a corporate and high-net-worth exodus to low-tax jurisdictions like Miami, ultimately harming the city’s tax base.
President Donald Trump also entered the fray, denouncing the policy as “totally misguided” and claiming it is “destroying New York.” Trump, whose own extensive real estate holdings in the city could be impacted, argued that such taxation serves only to drive away the international investors who fuel New York’s development.
Implementation remains a significant question mark, as the tax could potentially affect nearly 13,000 property owners, including major figures like Jeff Bezos. Financial analysts point out that many of the city’s most expensive apartments are held through complex offshore structures and shell companies, making the identification and appraisal of these properties an immense administrative challenge for the city.
As the debate intensifies, the Mamdani administration faces a difficult path ahead in balancing its “tax the rich” mandate with the practical realities of New York’s competitive global real estate market.

Iran Rebuffs Trump Announcement of New Peace Talks, State News Agency Reports
Iran rejected new peace talks with the United States, its state news agency reported on Sunday, hours after US President Donald Trump said he was sending envoys for talks in Pakistan and would launch new strikes on Iran unless it accepts his terms.
Trump posted on Truth Social that his envoys would arrive in Pakistan on Monday evening for negotiations, a timetable that would leave only a day for talks to make progress before a two-week ceasefire ends.
“We’re offering a very fair and reasonable DEAL, and I hope they take it because, if they don’t, the United States is going to knock out every single Power Plant, and every single Bridge, in Iran,” he wrote. “NO MORE MR. NICE GUY!”
Iran’s official IRNA news agency cited no specific source in its report that Iran had rejected the talks.
“Iran stated that its absence from the second round of talks stems from what it called Washington’s excessive demands, unrealistic expectations, constant shifts in stance, repeated contradictions, and the ongoing naval blockade, which it considers a breach of the ceasefire,” IRNA wrote.
The White House did not immediately respond to a request for comment on Iran’s rejection of the talks.
Earlier, a White House official said the US delegation would be headed by Vice President JD Vance, who led the war’s first peace talks a week ago, and also include Trump’s envoy Steven Witkoff and son-in-law Jared Kushner. Trump had initially told ABC News and MS Now that Vance would not go.
