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.

Shower, shelter, swipe: Israel’s ‘startup nation’ meets Iran war with a wave of apps

(JTA) — TEL AVIV — Smartphones have become as essential as shelters for Israelis riding out Iran’s missile attacks, with internet traffic up 25% since the war began on Saturday. From the screaming alerts of the military’s official app that, as one comedian put it, sound like a “baby dragon giving birth,” to bomb-shelter Tinder to multiple apps that tell you when it’s safe to shower, the startup nation is trying to digitize the panic into something more manageable.

At the serious end of the wartime app stack is Home Front Command, the Israeli army’s app available in Hebrew, Arabic, Russian and English. It uses GPS to figure out where you are and only pings you when your area is at risk, with separate alerts for rockets, missiles and terror incidents. In this war, Iran’s long-range fire has come with an extra layer of notice, a warning-before-the-warning that can buy people a few more minutes. The shorter-range threats from Hezbollah, which joined the fray on Tuesday, do not come with that same courtesy.

Bomb Shelter Locator turns shelter-seeking into a map exercise, listing around 20,000 official sites, offering offline city maps and walking routes, and estimating the time it will take to reach the nearest protected space.

For anyone who cannot sprint, Purple Vest tries to close the gap. People with disabilities or older residents can register in advance and request help during alerts, with volunteers using the app to locate them and assist with shelter access or urgent supplies.

For others, shelters are turning into accidental social spaces where people can meet-cute on a mattress. The Hooked app, originally built for speed-dating at events, now doubles as a bomb-shelter icebreaker. Shelter-goers post a QR code at the entrance, and singles who scan it can see who else in the same bunker has the same relationship status. US Ambassador Mike Huckabee — who has not been single since high school — shared it on X alongside the caption: “Someday they will tell their kids ‘we met on a dating app in a shelter while dodging ballastic [sic] missiles.’”

But for some, even showering has become its own risk calculation. Martine Berkowitz was one of many who vented after her attempts to scrub up were interrupted by missiles no less than five times on the second day of the war.

For software developer Ben Greenberg, a father of teenagers, Berkowitz’s complaint was familiar, so he built an app called Best Shower Time that spits out a percentage risk score on whether a shower is likely to be interrupted by an alert.

Posts about it spread on social media and what began as a tool for his family is now drawing about 5,000 visitors a day. Greenberg, a California native who immigrated to Israel from New York in 2018, insists it’s “not a joke app.”

“Sirens are just the ultimate example of lack of control in one’s life,” he said, describing the app as a way to “restore some level of control and predictability … in a time when that feels most vulnerable and most taken away from us.”

The app uses real-time alert data from the Home Front Command, and the score is based on four inputs: how long it has been since the last alert, the average gap between alerts over a six-hour window, whether the frequency is trending up or down, and the total alert count over the past 24 hours. Those are weighted into a single score that appears when you open the app.

Users can then set their own parameters, including how long a shower typically takes and how much buffer time they want afterward to dry off and reach shelter.

And for those who have a penchant for extended bathroom breaks, Greenberg added a separate option that relies on the same logic.

It’s not the only app homing on issues of basic cleanliness to emerge this week. Another app, Can I Shower Now?, has developed a following of its own.

Berkowitz said she was “grateful” for apps to help her navigate the question of whether to jump in the shower. After checking and seeing a 13% chance of a missile alert on Wednesday afternoon, she decided to risk it.

“I took a full 20-minute hot shower and washed my hair. It was lovely. And the next warning only came when I was finished and getting dressed,” she said.

Greenberg is piloting a new app, called Best Walking Time, based on the same principle and prompted by his wife, who regularly walks around the neighborhood during work calls but has been afraid to stray from home lest a missile head their way.

Gavin Newsom says some ‘appropriately’ call Israel an ‘apartheid state’ while questioning US military aid

(JTA) — California Gov. Gavin Newsom provided sharp criticism of the Israeli government during an interview this week, suggesting that he agreed with claims that it is an “apartheid state” and questioning U.S. military aid to the country.

Newsom, a likely 2028 presidential candidate, offered his rebuke of the Israeli government during an event on Tuesday with the hosts of “Pod Save America,” a political podcast, while promoting his new memoir, “Young Man in a Hurry: A Memoir of Discovery.”

During the conversation, while suggesting that Israel’s alleged influence over the United State’s strikes in Iran was “pretty damn self-evident,” Newsom took aim at Israeli Prime Minister Benjamin Netanyahu.

“The issue of Bibi is interesting because he’s got his own domestic issues. He’s trying to stay out of jail, he’s got an election coming up, he’s potentially on the ropes, he’s got folks, the hard line, that want to annex the West Bank,” said Newsom, adding that “others are talking about it appropriately as sort of an apartheid state.”

When a host of the podcast asked Newsom whether he believed the United States should consider “rethinking our military support for Israel,” the California governor replied, “It breaks my heart, because the current leadership in Israel is walking us down that path where I don’t think you have a choice.”

Newsom’s comments come shortly after the politician vowed he would “never” accept AIPAC funding, a stance that has increasingly become a litmus test for Democratic candidates amid record low support for Israel among its base.

While Newsom has been vocal in his critiques of Netanyahu in the past, saying earlier this year that he is “crystal clear in my love for Israel — and my condemnation of Bibi,” his latest comments signal a notable shift in tone as he adopts a more openly critical stance on Israel amid growing pressure from the Democratic party.

“I didn’t expect to be in that place, you know, a few years ago, let alone, you know, where we are today, and it’s accelerating in real time in a deeply, deeply alarming way,” said Newsom.

Calls to strip U.S. military aid from Israel have gained traction among progressive Democrats in recent months, with a record number of Senate Democrats voting to block weapons sales to Israel in July.

In January, Netanyahu said for the first time that he wanted to “taper off” U.S. military aid to Israel over the next decade, a goal that was quickly welcomed by South Carolina Republican Sen. Lindsey Graham as pockets of the Republican party have grown increasingly skeptical of U.S. aid to Israel.

Andrea Weiss, trailblazing Reform rabbi who merged scholarship and activism, dies at 60

(JTA) — Rabbi Andrea Weiss, a former provost of Hebrew Union College-Jewish Institute of Religion who made history as the first woman to ordain rabbis in the Reform movement, has died.

Weiss died on Tuesday surrounded by family at her home in Lower Merion, Pennsylvania, following a year-long battle with cancer. She was 60.

“Andrea brought lev shalem — a whole heart to everything she did,” Cantor Jill Abramson, HUC’s interim head of seminary and director of its Debbie Friedman School of Sacred Music, said in a statement. “Whether in a classroom or a hallway discussion, she has always been a model of what it means to live a life guided by scholarship and sacred purpose. We will miss her presence in these halls and hold her family in our prayers.”

Weiss’ death strikes another blow for the leadership of the Reform movement, which has also buried two leaders of HUC who died prematurely while Weiss worked there — Rabbi Aaron Panken, then the seminary’s president, in 2018, and Rabbi David Ellenson, its past president, in 2023. The school of sacred music, meanwhile, is named for another luminary of the movement who died prematurely at 59 in 2011.

Born on Sept. 9, 1965, Weiss was raised in San Diego where her family belonged to Temple Emanu-El. In 1987, Weiss received her bachelor’s degree from the University of California, Berkeley, and was ordained as a rabbi at HUC in 1993.

Weiss joined the HUC faculty in 2000 alongside Rabbi Lisa Grant, who served as the director of the school’s rabbinical program.

“There was actually four of us, four women, who started at the same time, and we really changed the whole gender balance of the faculty, which was very exciting and thinking about, long term potential of what that would mean for the culture of the school,” Grant told the Jewish Telegraphic Agency.

During her tenure at the school, Weiss led multiple initiatives including a curricular redesign, the launch of the Virtual Pathway for Rabbinical students and the creation of the Seminary Hebrew Program.

Weiss taught several courses at the school, including “The Poetry and Power of the Psalms,” “Literary Artistry of the Bible” and “Teaching Bible to Adult Learners,” a course she co-taught with Grant beginning in 2003.

“Rabbi Weiss has been a transformative presence at Hebrew Union College for more than two decades,” said the school’s current president, Andrew Rehfeld, in a statement. “Her scholarship, vision, and fierce commitment to the formation of Jewish clergy have shaped this institution in ways that will endure for generations. We are grateful beyond measure for her service and hold her and her loved ones in our hearts.”

Weiss received her PhD from the University of Pennsylvania in 2004, where her research centered on metaphor and biblical poetry, scholarship that informed her later work including her 2006 book, “Figurative Language in Biblical Prose Narrative: Metaphor in the Book of Samuel.”

In 2008, Weiss won the National Jewish Book Awards Book of the Year as the associate editor of “The Torah: A Women’s Commentary,” the first comprehensive collection of Torah commentary written entirely by female scholars. Sen. Elissa Slotkin chose the text to be sworn in on last year.

In 2016 and 2020, Weiss led a nonpartisan, interfaith initiative titled “American Values, Religious Voices” that brought together 100 faith leaders to write letters to former President Joe Biden and President Donald Trump as well as Congress during the first 100 days of their administrations. The letters were later published as two books.

Weiss described the initiative at the time as “a national, nonpartisan campaign created from the conviction that scholars who study and teach our diverse religious traditions have something important to say about our shared American values.”

Grant said Weiss offered a model of Jewish engagement that was validated by the ancient rabbis.

“There’s a great Talmudic debate about which is more important, which is greater, study or action, and the rabbis have this back and forth about it, and in the end, they conclude study because it leads to action,” Grant said. “She certainly lived that, that her study and her teaching led her to be an activist as well.”

In 2018, Weiss was appointed as HUC’s provost, becoming the first female rabbi to ordain rabbis in the Reform movement.

Grant said the honor was “extraordinarily meaningful and very heavy” for Weiss.

“She would make the time every year to meet individually for an hour with every single student, to hear about their story, their journey, their learning,” said Grant. “And she would craft that into a short blessing upon ordination.”

As news of Weiss’ death spread on Tuesday, many of her former students and rabbis whom she ordained eulogized her on social media.

“Rabbi Andrea Weiss helped me to grasp and appreciate biblical poetry in a way that nobody else could,” wrote Evan Schultz, the senior rabbi of Congregation B’nai Israel in Bridgeport, Connecticut, in a post on Facebook. “Her wisdom helped shape me as a rabbi and a writer. She was brilliant, kind, and genuine.”

Rabbi Binyamin Minich, the leader of Kehilat Daniel in Tel Aviv, recalled in a post on Facebook being a part of Weiss’ first ordination cohort.

“I remember this feeling of awe, understanding that our 2019 cohort of Israeli Rabbinical Program alumni would be the first ordained by a woman,” wrote Minich. “That meant the idea of women being rabbis settled fully in the Jewish contemporary life and ascended to a next level. It was the real proof of [lalmud velelemed leshmor vela’ashot] – ‘to study and to teach, to preserve and to act.’”

Rabbi Shira Koch Epstein, the executive director of Atra: Center for Rabbinic Innovation, recalled connecting with Weiss in 2019 in Jerusalem and hearing about a bar mitzvah project Weiss had helped organize for her son. The project brought his baseball team to Cuba, where they donated equipment and met with locals.

“It was a big project that they did that was really inspirational; it inspired my son, Ami, to do a baseball-related mitzvah project for his bar mitzvah,” said Epstein. “Definitely not as ambitious as theirs, but Rabbi Weiss really taught me both Torah and the living Torah, of how to turn what you care about and your interests into tzedakah and action in the world.”

Weiss is survived by her husband Alan; her two children, Rebecca and Ilan; her father, Marty; her siblings, Mitch, Laura and Roger; her sister-in-law Catherine; and her nieces, nephews and cousins.
