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.

What It’s Like in Israel — During ‘Operation Lion’s Roar’

I haven’t been sleeping much.
It starts with an (intentionally) obnoxious screech on your phone that overrides all your “leave me alone” settings, and harangues you that a missile alarm has gone off. The radar and satellite tech behind this disruptive howl is almost magical, but in the moment, no one cares.
Then the promised air raid sirens sound all around: you have 90 seconds to reach a bomb shelter.
Fortunately, there’s a bomb shelter in my building. Some aren’t so lucky: they run down the block to public shelters, or to Tel Aviv’s new underground subway, which was built with this exact scenario in mind.
The attacks come in waves of an hour or two.
Imagine having a baby that wakes you up all day and night, except instead of a baby it’s a homicidal Islamist regime, and instead of wanting to be changed or fed, it wants to kill you.

Israel has the most advanced, multi-layered missile defense system in human history, but it’s only about 88% effective — and that remaining 12% takes out entire apartment buildings. Iran already claimed its first victims in Israel and across the region.
This war is horrible, but there are many reasons Israel needed to wage it:
1. Iran is developing nuclear weapons.
This isn’t some Iraq era claim of “WMDs” — we know this is true because (among other reasons) Iran essentially says so. The regime very publicly insists on enriching uranium up to levels that have no possible use other than making warheads, all while paradoxically claiming “peaceful purposes.”
And if all that weren’t enough, Iran hides its “peaceful” nuclear program hundreds of feet under a mountain. Make of that what you will.
2. Iran is also developing ICBMs (intercontinental ballistic missiles) capable of reaching the United States. We know this because (again) the regime says so. A lot. They brag about it. This is not a question mark.
3. Iran’s terror proxies have killed thousands of Americans, Israelis, Europeans, and Arabs, including the Beirut barracks bombing that took the lives of 220 US Marines, and the unimaginable October 7 Massacre in Israel. Claiming that the work of proxies isn’t “really” Iran’s doing this is like hiring a hitman and then claiming that you didn’t “personally” murder anyone.
4. Of course, the greatest victims are the Iranian people, 80% of whom want to overthrow the regime — after 47 years of unimaginable suffering. This regime murdered thousands of its own people just last month, most for protesting, some for using Star Link terminals.
We seem to forget that military might can be used appropriately and effectively.
For every nightmare of intervention, such as Iraq or Afghanistan, there are also success stories, such as Libya, Kosovo, and most recently, Venezuela. And this isn’t even “intervention,” this is self defense. The regime’s President Masoud Pezeshkian declared in December, “we are in a full-fledged war with America, Israel, and Europe,” as Iranian officials continued to scream “Death to America” in the halls of Parliament, and on the streets.
And Iran puts its money where its mouth is: backing up its homicidal rhetoric with actual homicide. Lots of it.
Iran is now spreading a distorted history, claiming that all of its problems can be traced to America. That isn’t true: it’s a psyop, designed to weaponize our democracy against us. One can debate whether America should have helped affect a coup in Iran in 1953, but the leadership America helped bring to power back then (the “Shah”) is the very same leadership whose return the Iranian people are now risking their very lives to demand. America and the Iranian people are completely aligned in this, and the death of Ayatollah Khamenei was met by cheers and celebrations.
Genocidal maniacs have a way of telling us exactly what they plan to do: we ignored Hitler in the run up to World War II, we ignored Al-Qaeda in the years before 9/11, and we now ignore Iran at our peril.
But we’re not ignoring Iran.
We must hope that the people of Iran are ready to take back their country, and institute a new, organized government. It is entirely possible that Iran, the Middle East, and the world at large are on the verge of greater peace and stability than we have seen, or even imagined, in any of our lifetimes.
But we aren’t there yet, and we need the united support of all our allies, and our entire democracy, in order to succeed.

Family of Former FBI Agent Robert Levinson Demands Iran Be Held ‘Accountable,’ Return His Remains

The family of former FBI agent Robert Levinson, who disappeared in Iran in 2007 and is believed to have died while in Iranian custody, is calling on the Trump administration to make sure Tehran returns his remains and is held “accountable” for its actions following this weekend’s US-Israel airstrikes on the Islamic Republic.
Washington has maintained that Levinson, a retired FBI special agent, was taken by Iranian officials on March 9, 2007, while working as a private contractor for the CIA on the Iranian island of Kish, where he had traveled to meet a source. His family was never informed of what officially happened to the American citizen, but in 2020, the US government officially concluded he had died while in Iran’s custody. The details and circumstances surrounding his death remain unknown. Levinson was a father of seven children.
Levinson’s family issued a statement, shared on social media, following Saturday’s killing of Iranian Supreme Leader Ayatollah Ali Khamenei in the US-Israel airstrikes.
“For nearly 19 years, Iran has lied, obstructed, and refused to answer for the kidnapping, detention, and death of our father, Robert Levinson,” the family said in its statement. “Ayatollah Ali Khamenei led the regime responsible for these crimes. His death does not erase what Iran did to our father, and it does not end our fight for accountability. But it is a significant moment for our family and for every family that has suffered at the hands of this regime’s hostage-taking and wrongful detention.”
“Now Iran must do what it has refused to do for nearly two decades: provide full accountability for what happened to our father, return his remains to our family, and disclose the truth about his kidnapping, imprisonment, and death,” they added. “Our family will not stop demanding the truth. And we will not stop demanding justice.”
The family also expressed gratitude to US President Donald Trump and Secretary of State Marco Rubio “for using the power of the United States to confront Iran and to hold it accountable, including by recognizing and addressing Iran’s long-standing practice of wrongful detention.”
Levinson’s son, Dan Levinson, talked to “Fox & Friends” over the weekend about the need for the Trump administration to pressure Iran to take accountability.
“We’re just looking for answers. We still don’t know what exactly happened to him,” the younger Levinson said of his father. “There was no person more responsible for my father’s fate than Ayatollah Khamenei. At any time he could have waved his hand and had my dad released. He chose not to. We begged and pleaded. We sent so many letters. I went over there twice asking for a meeting and his people rebuffed us. Ignored us.”
Levinson said there is still a $25 million reward for information leading to the recovery and return of his father’s remains.
In March 2025, the United States imposed sanctions on three Iranian intelligence officers for their alleged involvement in Levinson’s disappearance.
In December 2020, the US Treasury Department’s Office of Foreign Assets Control sanctioned two other Iranian officials who are accused of authorizing Levinson’s 2007 abduction. The FBI released posters seeking information about them last year.

The Jewish space lasers are real — well, kind of
Everyone made fun of Marjorie Taylor Greene when she said that Rothschild-funded space lasers had caused forest fires.
But, as it turns out, the space lasers are real. Well, sort of. They aren’t starting forest fires or causing major weather events, as Greene claimed in her post. Israel does, however, have a laser that shoots in the general direction of space. But that’s enough for some conspiracy theorists to feel vindicated.
“No longer a ‘Conspiracy Theory.’ Israel just used a Directed Energy Weapon (DEWs),” reads one viral tweet about the lasers. “During Biden’s term the media worked relentlessly to Fact Check these weapons as conspiracy theories.”
Indeed, as Israel and Iran exchanged missiles over the weekend, videos circulated online purporting to show Israel shooting down missiles using a laser. In the video, missiles launched by Hezbollah from southern Lebanon, near the border with Israel, appear to flame out moments after taking off. (Israel has yet to officially confirm that the rockets were shot down by lasers, and the videos aren’t definitive; the missiles could have been defective and burned out on launch.)
But it is true that Israel has been working on defensive lasers for years. In 2022, Prime Minister Naftali Bennett said, “We have successfully completed a series of tests on our new ‘Iron Beam’ laser air defense system. This may sound like science fiction, but it’s real.” The laser system was reportedly delivered and deployed across Israel in December.
“It has nothing to do with the ‘Jewish space laser’ conspiracy theory,” said Mike Rothschild, a researcher on extremism and author of Jewish Space Lasers: The Rothschilds and 200 Years of Conspiracy Theories. “Conspiracy theorists often take real or in-development technology and twist it around for their own purposes.”
The laser works by shooting a grouping of small beams toward the projectile it is attempting to destroy, explains a report on the system’s development in National Defense Magazine. When one hits its target, the beams concentrate on the target until it is incinerated.
The lasers are less effective than the existing Iron Dome system, which works by intercepting missiles with other missiles and exploding them before they hit the ground. The laser can only reach missiles within about a 10 kilometer range, and, like any beam of light, can be blocked by terrain or atmospheric conditions like haze or clouds. On the other hand, the lasers are cheap to use, since they don’t require a ballistic missile for each engagement, and, for the same reason, they cause less collateral damage from falling debris.
The existence of the laser and its first — or first public — deployment has plenty of people joking about Jewish space lasers being real, and apologizing to Greene, though the Iron Beam has little to do with Greene’s allegations of a laser used to start targeted forest fires for government profit.
Conspiracy theorists may be crowing about the supposedly huge secret they’ve uncovered. But the laser isn’t secret at all. The Iron Beam is a well-funded and well-publicized project that has been in development for years, funded by both the U.S. and Israel. The first model was unveiled in 2014 at the Singapore Air Show. Smaller versions have been used to shoot down drones at close range for the past several years.
The aura of secrecy is key to the world of conspiracy theories. If antisemites can frame anything done by Jews or Israel as an underground, hidden project, it gains an undertone of corruption and danger.
The Iron Beam, however, has its own Wikipedia page. It features 40 sources — which means there are at least 40 other articles, going back over a decade, about the laser defense device. If you think that’s a secret, you’re just not paying attention.
