The temporary cease‑fire in the US‑Israel‑Iran war has given Iran and China a strategic opening to challenge the US dollar’s supremacy in global finance. Both nations share a common objective: to reduce reliance on the greenback, especially in the oil sector where, according to a 2023 JP Morgan estimate, roughly 80% of transactions are settled in dollars. In a practical step toward this goal, Iran’s de‑facto toll‑booth system in the Strait of Hormuz—a chokepoint that handles about one‑fifth of the world’s oil and LNG shipments—has started accepting transit fees in Chinese yuan. Lloyd’s List reported that at least two vessels had already paid in yuan by March 25, and China’s Ministry of Commerce later acknowledged the reports on social media. Iran’s embassy in Zimbabwe even called for the introduction of a “petroyuan” to the global oil market, underscoring the political symbolism of the move. While Tehran pledged to guarantee safe passage for two weeks under a US‑brokered cease‑fire, Beijing declined to comment. Harvard economist Kenneth Rogoff told Al Jazeera that Iran’s actions serve a dual purpose: they “poke a thumb in the United States’s eye” and provide a practical alternative to dollar‑based sanctions. Rogoff added that Iran’s shift to yuan aligns with China’s broader effort to redenominate trade among BRICS nations. For both countries, the yuan offers a way to sidestep US sanctions and lower transaction costs. Their trade relationship, cemented by a 25‑year strategic partnership signed in 2021, sees China buying over 80% of Iran’s oil—often at discounted rates—while Iran imports Chinese machinery, electronics, chemicals, and industrial components. Data from Kpler and TankerTrackers indicate that, despite the conflict, Iran’s oil exports to China have remained near pre‑war levels, ranging between 12 million and 13.7 million barrels in the first two weeks of hostilities. China’s ambition to elevate the yuan is long‑standing. President Xi Jinping, in a 2024 address, expressed hope that the yuan would become a global reserve currency. Yet significant hurdles remain: the yuan is not freely convertible due to strict capital controls, and the Chinese financial system is perceived as opaque, limiting broader adoption. According to the IMF, the dollar still dominated global foreign‑exchange reserves at 57% last year, far ahead of the euro’s 20% and the yuan’s modest 2%. Cross‑border trade settled in yuan rose to 3.7% in 2024, up from under 1% in 2012, per S&P; Global—an encouraging but limited shift. Natixis chief economist Alicia Garcia‑Herrero cautioned that the Strait of Hormuz experiment adds only “incremental pressure” and that a true “de‑dollarisation” would require Gulf states, which have priced oil in dollars since the 1970s in exchange for US security guarantees. European analyst Hosuk Lee‑Makiyama highlighted that China’s ability to supply Iran with essential goods makes the yuan a viable alternative, a dynamic not possible for Europe or Japan. He described China as the closest the world has seen to a “manufacturing one‑stop shop.” Consultancy founder Dan Steinbock echoed that while the dollar’s supremacy is unlikely to crumble overnight, the gradual increase in yuan usage could “chip away” at US dominance in specific sectors over time. Rogoff concluded that the long‑term impact hinges on the war’s outcome. If Iran and China emerge stronger, many countries may diversify away from the dollar to avoid US‑imposed financial constraints. Conversely, a decisive US victory could reinforce dollar hegemony for the foreseeable future.

Judith Rapoport, a leading child psychiatrist, passed away at 92, leaving a legacy defined by her groundbreaking work on obsessive‑compulsive disorder (OCD). Her 1989 book, The Boy Who Couldn’t Stop Washing, translated into more than twenty languages, presented complex research in a clear, jargon‑free style that resonated with a broad audience. OCD is characterized by compulsive rituals—re‑tying shoelaces, repeatedly checking switches, or incessant hand‑washing—that can dominate a person’s daily life. Before Rapoport’s book, many sufferers concealed their symptoms out of shame, unaware that they were not alone. Rapoport’s research demonstrated that OCD has a neurological foundation and may affect up to 2% of the population, challenging prevailing beliefs that it stemmed from overly strict parenting. She proved that the disorder can be hereditary and responsive to medication. In a pivotal 1989 double‑blind trial, she showed that the antidepressant clomipramine significantly reduced OCD symptoms, prompting the U.S. Food and Drug Administration to approve its use for the condition—a landmark moment in psychiatric treatment. Patients and colleagues credit her work with reducing stigma. "Reading Rapoport’s book washed away my shame," recalled Charles Gentz, who lives with OCD, while Professor Gabrielle Shapiro of the Icahn School of Medicine noted that the book “reduced the stigma for these people.” Rapoport herself reflected, “If my work alleviated just part of their pain, then it was not wasted time.” Born in New York City to a schoolteacher mother and a businessman father, she grew up with a literary lineage—her grandfather translated Ibsen into Yiddish. She excelled academically, graduating magna cum laude from Swarthmore College in 1955** and earning her medical degree from Harvard Medical School in 1959, where she met her husband, Stanley Rapoport. After early positions at Mount Sinai and the Massachusetts Mental Health Center, she and her husband secured fellowships in Sweden, conducting research at Uppsala University and the Karolinska Institute on women seeking abortions abroad. Returning to the United States, Rapoport joined the National Institute of Mental Health (NIMH) in 1976. There she led the institute’s child psychiatry branch from 1984, steering American psychiatry away from Freudian models toward a **biology‑focused** approach. Beyond OCD, she made significant contributions to the understanding of attention‑deficit hyperactivity disorder (ADHD) and childhood schizophrenia. Her 1978 study revealed that amphetamine improved concentration in both hyperactive and control children, contradicting the notion that stimulants only calm hyperactivity. Using MRI, she showed that childhood schizophrenia is progressive, involving loss of brain matter—a finding that shifted the focus from parenting to neurobiology. Rapoport’s expertise reached mainstream audiences through appearances on shows hosted by Oprah Winfrey and Larry King, further amplifying her message. By the time she retired in 2017, she had authored over 300 scientific papers, several books, and earned prestigious honors, including fellowship in the Institute of Medicine (1991) and the American Academy of Arts and Sciences (2000). Colleague Gabrielle Shapiro described her as “a pioneer who turned child psychiatry into a modern, evidence‑based discipline.” Outside the laboratory, she enjoyed music, theatre, hiking, and gardening. She is survived by her husband, two sons, and four grandsons.

The United States has long honored past presidents by naming airports, dams and monuments after them, but President Donald Trump is pushing the practice to an extreme, seeking to become the most commemorated leader in American history. Less than a year and a half into his second term, Trump’s brand has proliferated across government buildings, federal agencies and even consumer platforms. In February, the administration unveiled TrumpRx, a prescription‑drug website that listed only 43 medications—most of which are available as cheaper generics elsewhere—yet proudly displayed the former president’s signature and logo. Just weeks later, the White House and the U.S. Navy announced a new "Trump class" of battleships, billed as the "largest ever built." A Pentagon release noted that the Navy has not used battleships in combat for 35 years, suggesting the project is more a vanity exercise than a strategic necessity. Federal institutions have not been spared. In December 2025 the U.S. Institute of Peace was renamed the "Donald J. Trump United States Institute of Peace," a move the White House framed as a reminder of "strong leadership" for global stability—just weeks before the administration launched a military strike on Iran. Trump’s influence extended to the arts when, in February 2025, he appointed a new board to the John F. Kennedy Center for the Performing Arts and installed himself as chair. The board voted in December to rename the venue the "Donald J. Trump and John F. Kennedy Center," a change that immediately faced a legal challenge. Republican lawmakers have largely embraced the naming spree. One congressman introduced legislation to carve Trump’s likeness onto Mount Rushmore, while another proposed naming a major airport after him, underscoring the party’s willingness to reward the president’s personal brand. Political scientist Steven Levitsky of Harvard warned that Trump operates "unconstrained" by advisers or party elders, noting that today’s Republican ambition often hinges on pleasing the president, including attaching his name to public projects. Visual propaganda has also surged. Giant banners bearing Trump’s image now hang from the Department of Justice and the Department of Labor buildings, a rarity for a sitting president and a practice more typical of authoritarian regimes, according to Princeton sociologist Kim L. Scheppele. Beyond buildings, the administration has pursued numismatic honors. A 24‑karat gold coin featuring Trump standing over a desk was approved by a hand‑picked arts commission, and drafts of a new $1 coin displayed an air‑brushed profile of the former president. The Treasury Department announced that Trump’s signature will appear on U.S. paper currency later this year, a move Treasury Secretary Scott Bessent described as a "powerful way to recognize historic achievements" of the nation. Critics argue that the public does not share the president’s enthusiasm. The 2026 National Parks Pass, which traditionally showcases natural scenery, sparked outrage when a draft featured Trump’s stern face with a spectral George Washington behind him. A cottage industry of stickers emerged to cover the image, forcing the National Park Service to warn that such alterations could void the pass. White House spokesperson Davis Ingle defended the branding, claiming it reflects Trump’s “vast accomplishments,” including the largest tax cut in history and border security measures. Yet scholars and opponents contend that the relentless self‑promotion blurs the line between public service and personal aggrandizement. As the branding campaign continues, legal challenges, public pushback, and questions about fiscal priorities suggest that Trump’s quest to name everything after himself may soon encounter more than just decorative resistance.

The Shift from Silent Infrastructure to Political FlashpointFor years, data centers operated as the silent backbone of the digital economy, largely unnoticed by the communities they served. However, recent polling data suggests this era of quiet expansion is ending. A growing wave of local opposition is turning data centers into a contentious political issue, forcing tech companies to confront the reality that their infrastructure is no longer welcome in everyone's backyard.Discrepancies in Public Sentiment: Harvard/MIT vs. QuinnipiacThe debate is split, with conflicting data highlighting the complexity of public opinion. A Harvard/MIT poll conducted in November offers a moderate view, finding that 40% of respondents supported the construction of a data center in their area. However, this support drops significantly when compared to industrial facilities, with 32% opposing the idea.Harvard/MIT Poll (Nov): 40% support data centers; 32% oppose.Quinnipiac Poll (March): 65% oppose AI data centers; 24% support.A fascinating insight from the Axios report notes that public preference shifts dramatically based on the facility type: more people would rather have an e-commerce warehouse than a data center.The Economic Trade-off: Jobs vs. Power CostsThe core of the conflict lies in the perceived benefits and drawbacks of these facilities. While data centers promise economic growth, a significant portion of the population is skeptical. Two-thirds of respondents in the Harvard/MIT survey expressed concern that a new data center would nudge electricity prices higher.Conversely, e-commerce warehouses are viewed more favorably, likely due to the tangible promise of local jobs and economic stimulation. However, analysts warn that this sentiment may be short-lived, as most data center projects employ very few people once operational, unlike the labor-intensive nature of warehousing.From Local Zoning to National Policy: The Future of Data Center RegulationThe divergence in polling numbers—from the moderate 40% support to the sharp 65% opposition—suggests that the data center debate is far from settled. As these facilities continue to proliferate, the discontent is likely to spill over into politics.With the "quiet" era of data center expansion effectively over, we can expect a surge in local zoning battles and potential federal regulation aimed at managing the energy consumption and community impact of AI infrastructure.

The recent statements and actions by the US, particularly by President Donald Trump, have raised serious concerns about potential war crimes under international law. During a national address, Trump warned that if Iran did not reach a deal with him, the US would target Iranian electric-generating plants and reduce the country to the 'stone ages.'Legal experts and human rights organizations have strongly criticized these threats. Erika Guevara Rosas, Amnesty International's senior director of research, advocacy, policy and campaigns, emphasized that intentionally attacking civilian infrastructure, such as power plants, is generally prohibited under international law. Such actions could cause disproportionate harm to civilians and are considered unlawful and potentially war crimes.More than 100 US experts in international law from prestigious universities, including Harvard, Yale, and Stanford, have expressed similar concerns. They highlighted Trump's comments, including the statement that the US may conduct strikes on Iran 'just for fun,' and Defense Secretary Pete Hegseth's remarks about not fighting with 'stupid rules of engagement.'The experts and legal experts point to the principle of distinction in international humanitarian law, which requires parties to avoid targeting civilian objects. Article 52 of the Geneva Conventions defines civilian objects as those that are not military objectives, and it is a war crime to intentionally direct attacks against them if they are not military objectives.Human rights organizations and experts warn that targeting Iran's power plants would have a devastating impact on the civilian population, affecting hospitals, water supplies, and other vital needs. Sarah Yager, Washington director of Human Rights Watch, noted that such actions would be catastrophic for the Iranian people.

Scientists have shed new light on the mating habits of octopuses, revealing that male octopuses use a specialized arm to detect female hormones and mate without visual contact.The arm, called the hectocotylus, is used to place a package of sperm inside the female's reproductive system. Researchers at Harvard University have found that this arm is a sensory organ, similar to a tongue, that can detect the female hormone progesterone.This allows the male to seek out and fertilize a mate, even if it cannot see its sexual partner. The study, published in the journal Science, shows that the arm is both a sensor and a mating organ, and that it plays a crucial role in the mating process.The researchers, led by Prof Nicholas Bellono, found that the arm can detect progesterone through receptors on its tip, and that this sensitivity is specific to progesterone and not other hormones.The study provides new insights into the evolution of sensory systems and the importance of chemical cues in mating behavior. It also highlights the complex and fascinating world of octopus biology, and the importance of continued research into the natural world.

Tracy Kidder, an award-winning narrative nonfiction writer, has passed away at the age of 80. Kidder was known for his ability to transform unlikely subjects into bestsellers, captivating readers with his in-depth research and storytelling skills. Throughout his career, Kidder immersed himself in various worlds, producing richly researched books on topics that may not have seemed like light reading. His work included The Soul of a New Machine, which explored the inner workings of a fledgling computer company in Silicon Valley and earned him the Pulitzer Prize and National Book Award in 1981. Kidder's other notable works include Among Schoolchildren, which highlighted the dedication of an inner-city teacher in Holyoke, Massachusetts, and Old Friends, which chronicled the lives of two friends in a nursing home. His book Mountains Beyond Mountains, about a doctor's efforts to bring healthcare to Haiti, introduced his work to a new generation of readers and inspired numerous universities to add it to their reading lists. Kidder's approach to storytelling was rooted in his belief that small things can have a significant impact. He avoided focusing on his personal interests, such as fishing or baseball, to maintain his objectivity and enthusiasm for his subjects. Kidder saw himself as a storyteller, not a 'literary journalist' or 'creative nonfiction' writer, and believed that nonfiction should not be limited by traditional techniques. Born in New York City in 1945, Kidder attended Harvard University and served in Vietnam, where he documented his experiences in My Detachment, a memoir that offered insights into the lives of support troops.
