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.

Volatility, Hit Frequency, and RTP: Why the Number Casinos Advertise Is the Least Useful One
The return to player percentage looks clean as a casino data point. It gives players a neat number, usually around 94% to 97% for many online slots, and that number feels easy to compare. A 96.5% game appears better than a 95.2% game. The problem starts when players treat RTP as a forecast for their next 50 spins or one evening.
You may find the RTP listed on slot pages on a leading online casino in Ontario, but the number only tells part of the story. Two games can share the same RTP and create different sessions: one may return small wins often, while the other may drain a balance before one bonus round changes everything.
The RTP Trap
Return to player (RTP) measures the theoretical share of total wagers a game returns across a very large number of rounds. In plain terms, a 96% RTP slot returns about $96 for every $100 wagered in the long run. That does not mean one player who deposits $100 should expect $96 back.
The trap sits in the word “theoretical.” RTP comes from the game’s math model. It works across huge samples, not personal sessions. A player can finish far above that percentage, far below it, or with nothing left after a short run of poor results.
Is it useless then? No, RTP can still help. It gives a baseline cost of play. Lower-RTP games cost more on average than higher-RTP games. Still, once a game passes a reasonable threshold, the next question matters more: how does it distribute that return?
Hit Frequency: The Number That Shapes Session Feel
Hit frequency tells you how often a game produces a winning outcome. This often misleads players because any win can count. A spin that returns $0.10 on a $1 bet may still count as a hit, even though the player lost $0.90 in real terms.
A game can feel active because symbols connect often, sounds play, and the screen keeps celebrating small returns. The balance may still fall. In many modern slots, “win” does not always mean profit on the spin.
Hit frequency answers one practical question: how much silence can you tolerate? Some players dislike long dry spells. Others accept quieter sessions because they chase bonus rounds or larger payouts.
The educational site Get Gambling Facts gives a useful distinction: RTP concerns the percentage of money returned over time, while hit frequency concerns how often a machine stops on a winning combination.
Volatility: The Risk Label Players Need More Often
Volatility, also called variance, describes how unevenly a game pays. Low-volatility games tend to return smaller amounts more often. High-volatility games hold more value in rare events: bonus rounds, premium symbols, multipliers, or jackpots.
Here is where RTP becomes less useful on its own:
- A 96% low-volatility slot may give modest returns and longer play from the same balance.
- A 96% high-volatility slot may burn through funds quickly unless the player hits a strong feature.
- A progressive jackpot game may look exciting, but it often places more value on rare top prizes.
The same RTP can hide very different risk profiles. Players who ignore volatility often blame the casino or the game when the session follows its math design.
Why the Same RTP Can Feel So Different
Picture two slots with 96% RTP. Slot A pays small wins on many spins, has a modest top prize, and rarely creates dramatic balance swings. Slot B pays less often but offers a large max win and volatile bonus rounds. The advertised return matches, but the experience does not.
Slot A may suit a player who wants a slower bankroll drop and more regular feedback. Slot B suits someone who accepts sharper losses in exchange for a shot at a heavier payout.
A Better Way to Read a Slot Page
Most slot pages give players more clues than they notice. The trick is to read the details together rather than chase the highest percentage.
Start with RTP. If two games look similar, the higher number has better long-term value. Then check volatility. If the game uses terms such as high, very high, or extreme variance, lower your bet size or expect shorter sessions. Next, look at the paytable. A huge max win usually means the game saves a lot of its value for rare outcomes.
A sensible pre-play check looks like this:
- RTP: What is the average long-term return?
- Volatility: How rough can the session become?
- Hit frequency: How often will the game show any wins?
- Paytable: Where does most value sit?
To Conclude
Casinos advertise RTP because it looks objective, tidy, and easy to rank. Players should read it, but they should not give it more authority than it deserves. For long sessions, volatility may matter more than a small RTP difference. For comfort, hit frequency may explain the feel better than the payback rate.

Lahmeyer, pastor who says Antichrist will be Jewish, heads to Oklahoma GOP runoff
(JTA) — Jackson Lahmeyer, a pastor who supports Israel and believes the Antichrist will be Jewish, is headed to a runoff in his district’s Oklahoma congressional primary.
The Donald Trump-backed Lahmeyer will face off against Mark Tedford, a member of the state House of Representatives from Tulsa, in the August runoff to decide who will be the Republican candidate for Congress in Oklahoma’s 1st Congressional District.
The runoff will pit candidates with two very different approaches to politics, and Israel, against each other at a time when the Republican Party is divided on multiple lines. Lahmeyer is part of Trump’s MAGA movement, while Tedford is a more traditional conservative. Both men promote a hard line on immigration, but Lahmeyer’s rhetoric has been peppered with incendiary claims about efforts by Muslims to establish “sharia law” in the United States.
While both competitors are also evangelical Christians with training in ministry, Lahmeyer works as a pastor and preaches an end-times theology that includes an Antichrist with Jewish heritage. Lahmeyer is also a vocal supporter of Israel, in keeping with his Christian Nationalist outlook, while Tedford has made few if any public comments about Israel or the war in Gaza.
The two candidates pulled far ahead of the pack in Tuesday’s crowded primary, which attracted 11 candidates to fill an open seat. Tedford received 32.1% of the votes, and Lahmeyer drew 25.9%, according to the Oklahoma State Election Board.
Lahmeyer had been seen as a favorite, but his star fell in the days before the election amid revelations that he had been unfaithful to his wife. (He said the episode, which he confirmed, was a private matter and in the past, and Trump reaffirmed his endorsement following the revelation.)
Few if any of the nine candidates who did not make the runoff are part of the MAGA movement, suggesting that Tedford could see more of their supporters turn to him in November.
“We need everyone who came out today to keep fighting until we succeed,” Lahmeyer said in a statement to local media. “Let’s send a Trump-endorsed warrior to fight for Oklahoma values in Congress.”
The district is solidly red, virtually assuring the primary winner of victory in November. The Democratic candidate, John Croisant, is a Tulsa school board member who has not spoken publicly about Israel or Gaza, issues that are occupying some Democrats.

Democratic socialist whose Israel criticism ignited Jewish leaders’ concern leads D.C. mayoral primary vote
(JTA) — A democratic socialist who has sharply criticized Israel and pledged to defend Jews from antisemitism is in the lead in Tuesday’s Democratic primary for mayor in Washington, D.C., poising the nation’s capital to elect a progressive leader.
Janeese Lewis George, a D.C. Council member, had received just over half of the 65% of votes that had been counted by Wednesday morning. Kenyan McDuffie, a moderate and former City Council member, was in a distant second place.
The election is D.C.’s first using ranked-choice voting, so it could take some time to reach a final tabulation and the results could change. Still, the early results have ignited optimism among Lewis George’s supporters — and concern among her critics, who include Jewish leaders in the city and beyond.
Some Jewish leaders have criticized Lewis George, who has accused Israel of committing genocide in Gaza, for vowing if elected not to attend “events focused on obfuscating the realities of occupation or promoting Zionism and apartheid” or join “political junkets to Israel.” She made those promises in responses to a questionnaire from the Metro D.C. Democratic Socialists of America, which subsequently endorsed her.
The race set up a fight over the future of Washington, D.C., where the vast majority of voters are Democrats and the threat of President Donald Trump’s interference in city affairs loomed large over the ballot box. The winner is heavily favored to win the general election in November and succeed Democratic Mayor Muriel E. Bowser, who is retiring after 12 years in office.
It also has fueled a national discourse about the growing viability of far-left, anti-Israel politicians in local politics. Some have likened Lewis George to Zohran Mamdani, the democratic socialist elected mayor in New York City last year. A left-wing candidate is also poised to potentially become mayor of Los Angeles, while Chicago has had a progressive Democrat who is sharply critical of Israel since 2023.
The Wall Street Journal said ahead of the D.C. primary that the city was facing “a Mamdani moment” — a sharp critique from the paper’s conservative editorial board.
The leader of Our Revolution, a progressive group founded by Sen. Bernie Sanders, also embraced the comparison, telling USA Today that the success of left-wing candidates including Lewis George and Mamdani showed that voters want change.
Lewis George’s platform focuses largely on making D.C. more affordable. But controversy dogged her after her DSA questionnaire was published.
Ron Halber, head of the Jewish Community Relations Council of Greater Washington, told The Washington Post that the questionnaire raised “a lot of concern about whether an administration of hers would be sensitive to the Jewish community or not.”
Lewis George said in the DSA questionnaire that she would continue to meet with people and organizations that do not share all her values and opinions. She referenced a meeting she attended that was hosted by the JCRC, saying she disagreed with the group’s “opposition to using the word ‘genocide’ to describe Israel’s actions in Gaza” as well as “their definition of anti-semitism that criminalizes dissent, and their attacks on activists” but could also see areas of shared interest.
“I went to the event to advocate for an end to ICE collaboration, seek allies in that effort, and build on our shared goal of ending the inhumane treatment of our neighbors who are being taken by ICE,” she said.
Lewis George was endorsed by the Jews United for Justice Campaign Fund, which says it promotes economic, social and racial justice. The group said in its endorsement announcement that Lewis George would “fight for our communities and our Jewish values.”
After blowback to the DSA questionnaire, Lewis George privately met with local rabbis and Jewish community leaders in March to hear their concerns, according to Jewish Insider. Shortly after, she said in a statement on her campaign website that her “support for Palestinian human rights” and her “commitment against antisemitism” were not in conflict.
She added, “To the Jewish community in DC: I will not be a mayor who includes or excludes you based on your opinions or feelings on matters here and across the world. I will always protect your freedom, safety, and sense of belonging.”
Lewis George also said she had visited synagogues since she was in middle school and frequently worked with Jewish organizations as a council member, including to obtain security grants for synagogues and schools.
She went on to list her credentials as a supporter of Palestinians, saying that she was among the first Council members to call for a ceasefire in Gaza and meet with George Washington University students advocating for a ceasefire.
The DSA strongly opposes the Israeli government and requires candidates to share their views on Israel to secure an endorsement. While the party remains controversial in the Democratic establishment, Democrats nationwide have shifted their sympathies away from Israel since 2023, with 65% saying their sympathies lie more with the Palestinians in a February Gallup poll.
McDuffie criticized Lewis George’s answers to the DSA questionnaire and said there was “no place in this city for shutting out any community,” according to Washington Jewish Week. But he has largely avoided weighing in on questions about Israel, telling Jewish Insider that it was not the mayor’s role to craft foreign policy.
The Middle East receded to the background in the closing days of the mayoral race, which focused heavily on high costs of living in the district and fighting the Trump administration. Lewis George and McDuffie both argued they were better equipped to block interference from the federal government, as National Guard troops continue to patrol the streets amid Trump’s crackdown on immigration and tens of thousands of residents have lost their government jobs.
Meanwhile, Trump threatened at the Oval Office on Thursday to “take back” Washington and “run it on the federal basis” if Lewis George won.
The Tuesday primary used ranked-choice voting, which allows voters to rank up to five candidates. If no candidate reaches 50%, the last-place finisher is removed and voters for that candidate have their votes distributed among their second choice candidates. The process continues until one candidate has a majority. This voting method means that a final tally of results can take days after polls close.
