Raphael Mechoulam, Israel’s ‘father of cannabis research,’ dies at 92
(JTA) — In the early 1960s, a Bulgarian-born scientist named Raphael Mechoulam was caught carrying five kilograms of, as he called it, “superb, smuggled Lebanese hashish” on a bus from Tel Aviv to Rehovot. But he wasn’t planning on smoking the stuff.
Mechoulam was a fledgling researcher keen on exploring the science behind cannabis, a stigmatized plant whose specific medical properties were not yet known. Over the decades he became a pioneer in cannabis research, whose findings about the psychoactive substance helped ease its entry out of the counterculture and into the mainstream.
Mechoulam died in Israel at age 92; his death was announced Friday by American Friends of the Hebrew University, where Mechoulam helped form The Hebrew University Multidisciplinary Center for Cannabinoid Research in 2017.
“Most of the human and scientific knowledge about cannabis was accumulated thanks to Prof. Mechoulam,” Hebrew University President Asher Cohen said in a statement. “He paved the way for groundbreaking studies and initiated scientific cooperation between researchers around the world. Mechoulam was a sharp-minded and charismatic pioneer.”
As a professor in the Hebrew University School of Pharmacy, Mechoulam and his research team isolated THC, the psychoactive component of cannabis, as well as cannabidiol, or CBD, an active ingredient in cannabis with a range of medicinal benefits.
He also pioneered the study of the body’s own cannabinoid system, which produces chemicals similar to THC to help regulate appetite, manage pain and operate the immune system.
As Mechoulam discovered more about cannabis and its efficacy in easing symptoms of cancer, epilepsy and other diseases, he lamented that strict drug laws in the United States and elsewhere suppressed research and kept the derivatives of cannabis off the market.
“Medicinal cannabis has to follow medical lines of thought and development and modern medical routes” in order to be part of proper drugs, he told the New York Times in 2017. “Israel has more [clinical trials] than the United States at the moment, which is ridiculous.”
Mechoulam was a founding member of the International Association for Cannabinoid Medicines and the International Cannabinoid Research Society. In 1994, he was elected to be a member of the Israel Academy of Sciences and Humanities.
Mechoulam was born in Bulgaria in 1930 and immigrated in 1949 with his family to Israel, where he later studied chemistry. He received his PhD at the Weizmann Institute in Rehovot, writing a thesis on the chemistry of steroids. After postdoctoral studies at the Rockefeller Institute in New York, he joined the scientific staff of the Weizmann Institute.
Mechoulam became a full professor at Hebrew University in 1972 and was named the Lionel Jacobson Professor of Medicinal Chemistry in 1975, serving as the university’s rector from 1979-1982.
In 2022, the YIVO Institute for Jewish Research in New York City mounted its exhibition on Jewish contributions to the history of cannabis and highlighted the work of Mechoulam. “He’s worked on cannabis his entire life, and in the 1990s he and his colleagues discovered the endocannabinoid system, which regulates homeostasis — a significant discovery on how the human body deals with cannabinoids,” Eddy Portnoy, who curated the exhibit, told the Jewish Telegraphic Agency at the time. “I read an interview with him where he says that because he was in a small country, he would have to find a niche that other people weren’t working in.”

London Police Set Up Specialist Jewish Protection Team

British police are setting up a new team of 100 officers including counter terrorism specialists to help protect Jewish communities across London after a series of antisemitic attacks including the stabbing of two men.
The plan announced on Wednesday for a dedicated protection team comes as officers announced more arrests for antisemitism, including detaining a 35-year-old man on Saturday after rocks were thrown at an ambulance belonging to the Jewish community.
London‘s top police boss Mark Rowley said Jewish communities were facing “sustained threats” from hostile state actors as well as extreme right-wing groups, elements of the extreme left, and Islamist terrorists.
Detectives are examining whether the arson incidents have possible Iranian links, after British security officials warned that Iran was using criminal proxies to carry out hostile activity.
Since late March, there have been a number of high-profile arson attacks with four Jewish ambulances burned and synagogues targeted. Last week, two Jewish men were also stabbed. Both victims survived the attack.
Over the past four weeks, police said they had arrested around 50 people for antisemitic hate crimes and charged eight individuals. On top of that, 28 arrests have been made as part of investigations alongside counter terrorism policing for arson and other serious incidents.
“This new team will be primarily focused on protecting the Jewish community, which faces some of the highest levels of hate crime alongside significant terrorist and hostile state threats,” said a statement from London‘s Metropolitan Police force.
British Prime Minister Keir Starmer convened a meeting on Monday with business, health and cultural leaders aimed at trying to tackle antisemitism.

Iran Reviewing US Proposal to End War, Though Key Demands Remain Unaddressed

Iran said on Wednesday it was reviewing a US peace proposal that sources said would formally end the war while leaving unresolved the key US demands that Iran suspend its nuclear program and reopen the Strait of Hormuz.
An Iranian foreign ministry spokesperson cited by Iran‘s ISNA news agency said Tehran would convey its response. US President Donald Trump said he believed Iran wanted an agreement.
“They want to make a deal. We’ve had very good talks over the last 24 hours, and it’s very possible that we’ll make a deal,” Trump told reporters in the Oval Office on Wednesday.
Earlier in the day, Trump had sounded more pessimistic about the chances of a deal. In a Truth Social post, he threatened to restart the US bombing campaign in Iran, calling the possibility of Tehran agreeing to the latest US proposal a “big assumption.”
Trump has repeatedly played up the prospect of an agreement that would end the war that started Feb. 28, so far without success. The two sides remain at odds over a variety of difficult issues, such as Iran‘s nuclear ambitions and its control of the Strait of Hormuz, which before the war handled one-fifth of the world’s oil and gas supply.
A Pakistani source and another source briefed on the mediation said an agreement was close on a one-page memorandum that would formally end the conflict. That would kick off discussions to unblock shipping through the strait, lift US sanctions on Iran, and set curbs on Iran‘s nuclear program, the sources said.
It was unclear how the memorandum differs from a 14-point plan proposed by Iran last week, and Iran has yet to respond to the latest US proposal.
Iran‘s semi-official Tasnim news agency, citing an unnamed source, said the US proposal contained some unacceptable provisions, without specifying which ones.
Iranian lawmaker Ebrahim Rezaei, a spokesperson for parliament’s powerful foreign policy and national security committee, described the text as “more of an American wish-list than a reality.”
“The Americans will not gain anything in a war they are losing that they have not gained in face-to-face negotiations,” he wrote on social media.
OIL PRICES TUMBLE
Reports of a possible agreement caused global oil prices to tumble to two-week lows, with benchmark Brent crude futures falling around 11% to around $98 a barrel at one point before rising back above the $100 mark.
Global share prices also leapt and bond yields fell on optimism about an end to a war that has disrupted energy supplies.
Trump on Tuesday paused a two-day-old naval mission to reopen the blockaded strait, citing progress in peace talks.
The US military has kept up its own blockade on Iranian ships in the region. US Central Command said forces fired at an unladen Iranian-flagged tanker on Wednesday, disabling the vessel as it attempted to sail toward an Iranian port in violation of the blockade.
NO MENTION OF KEY US DEMANDS
The source briefed on the mediation said the US negotiations were being led by Trump’s envoy Steve Witkoff and son-in-law Jared Kushner. If both sides agreed on the preliminary deal, that would start the clock on 30 days of detailed negotiations to reach a full agreement.
The full agreement would end the competing US and Iranian blockades on the strait, lift US sanctions, and release frozen Iranian funds. It would also include some curbs on Iran‘s nuclear program, with the aim of a pause or moratorium on Iranian enrichment of uranium.
While the sources said the memorandum would not initially require concessions from either side, they did not mention several key demands Washington has made in the past, which Iran has rejected, such as curbs on Iran‘s missile program and an end to its support for proxy militias in the Middle East.
The sources also made no mention of Iran‘s existing stockpile of more than 400 kg (900 pounds) of near-weapons-grade uranium.
Israeli Prime Minister Benjamin Netanyahu, Trump’s ally against Iran, said on Wednesday the two leaders agreed that all enriched uranium must be removed from Iran to prevent it from developing a nuclear bomb.
Tehran denies wanting to acquire a nuclear weapon.

Brussels cathedral installs plaques apologizing for medieval antisemitic persecution depicted in stained glass
(JTA) — More than 650 years after Jews in Brussels were executed and expelled following false antisemitic accusations, church officials at the Cathedral of St. Michael and St. Gudula have installed a plaque apologizing for the persecution commemorated in its stained glass windows.
At a ceremony on April 27, Archbishop Luc Terlinden of Mechelen-Brussels and Rabbi Albert Guigui, the chief rabbi of Brussels, unveiled four plaques, written in Dutch, French, English and Hebrew, providing historical context for the windows and an apology for the antisemitic persecution tied to the events they depict.
The plaques, which Terlinden signed, state that “baseless accusations of the desecration of the Eucharistic host were made against Jewish communities” in medieval Europe and that the accusations “led to persecution, massacres, and unjustifiable expulsions.” The windows show Jews being executed at the stake in response to their alleged attacks on the Eucharist, bread that Catholic doctrine considers a literal representation of Jesus’ body.
“Theological and social anti-Judaism is in direct contradiction with the Gospel of Christ, which calls for truth, justice, and brotherhood,” the plaques say. “We ask forgiveness from the Jewish people for the suffering these accusations have caused.”
The stained glass windows in the cathedral depict the “Brussels Host Desecration,” an antisemitic accusation in 1370 that Jews had desecrated communion wafers, leading to the execution of Jews in Brussels and the expulsion of the city’s Jewish community.
The windows have drawn scrutiny for decades, particularly as the Catholic Church sought to reckon with its history of antisemitism. In 1969, shortly after the landmark Nostra Aetate declaration rejecting longstanding anti-Jewish Catholic doctrine, the Archbishop of Brussels ordered that several paintings be removed and a plaque be mounted to offer context about the remaining depictions.
Several years later, the European Jewish Congress noted last week, Catholic leaders did install a plaque that drew readers’ attention to “the biased nature of the accusations [against the Jews accused of the desecration] and to the legendary presentation of the ‘miracle.’”
But Flora Cassen, the director of the Brandeis Center for Jewish Studies and a scholar of European antisemitism, said the existing plaque was “very ambiguous about the responsibility and what happened” and installed in an easy-to-miss location. The new plaques, she said, contain a clear and “very moving” apology and cannot be missed by anyone who comes to see the windows.
“The significance is enormous of the church finally putting a plaque there that tells the story, that acknowledges the antisemitism behind it, that acknowledges that it was a slander and that it resulted in persecution and in the execution of Jews in Brussels and their expulsion,” Cassen said.
The new plaques cite Nostra Aetate and the Catholic Church’s subsequent effort under Pope John Paul II to reckon with historical antisemitism in 2000. They affirm the church’s “commitment to combat all forms of antisemitism, to deepen dialogue between Jews and Christians, and to pass on to future generations a clear remembrance, based on the acknowledgement of truth and mutual respect.”
While some have called for the historic windows to be removed, Guigui said in a statement that the plaques represented an appropriate way to address relics of historical antisemitism.
“What matters today is how we look at these images,” the rabbi said. “They must not be erased, because they are part of history, but they must be accompanied by explanation and moral insight in order to understand the context and avoid repeating past mistakes.”
