The Lead: Biotech Barbie's Mission to Edit Human DNA Cathy Tie, a Canadian entrepreneur known as "Biotech Barbie," is pursuing a controversial mission to genetically modify embryos to prevent hereditary diseases, following in the footsteps of her ex-husband He Jiankui, who served prison time for creating the world's first gene-edited babies. Despite global bans on germline gene editing for reproductive purposes, Tie aims to conduct this work openly with regulatory approval and venture capital funding. The Technical Breakthrough: Gene Editing Made Accessible Since the invention of the Crispr-Cas9 gene editing tool in 2012, the technical process of altering DNA has become relatively straightforward. "The hardest thing about genetically engineering a baby is getting permission to do it; the technical part is not particularly complicated," the article explains. The process is compared to using "find, copy, cut and paste functions on a computer" and doesn't require extensive expertise in molecular biology. Germline gene editing—altering eggs, sperm, or early embryos—is particularly significant because changes are passed down to future generations, potentially altering human evolution permanently. This is why such procedures are banned in the UK, US, and China, with international agreement against research that could result in gene-edited babies. The Financial Landscape: Billionaires Investing in Genetic Engineering Money is flowing into human genetic engineering, with some of the world's richest men investing in companies pursuing similar goals. Preventive, a gene editing startup launched in October 2025 with the aim of "preventing disease before birth," has attracted investment from OpenAI's Sam Altman, his husband Oliver Mulherin, and Coinbase CEO Brian Armstrong. Armstrong has coined the term "the Gattaca stack"—referencing the dystopian film about a genetically engineered society—which includes technologies for "disease prevention, or enhancement" of babies. This suggests a growing interest not just in preventing diseases but in enhancing human traits. Preimplantation genetic testing (PGT), already common in the US fertility treatments, allows parents to "choose the embryo that best matches what you want," with companies like Nucleus Genomics advertising on subways with the tagline "Have your best baby." The Global Impact: A New Biological Arms Race? "There's a big geopolitical component to this," Tie states, referring to the growing interest in genetic engineering. China, where Tie was banned from entering, has already demonstrated what gene editing can do—Chinese researchers made the first edits to human embryos in 2015, and Tie's ex-husband He Jiankui created the first gene-edited babies, twin girls known as Lulu and Nana. Since his release from prison in 2022, He has become an unlikely social media star with close to 150,000 followers on X, making unrepentant posts about "designer babies" being "inevitable." Meanwhile, China's biotechnology ambitions have expanded, with Premier Li Qiang announcing new regulations emphasizing "the need to promote innovative development" and "accelerate R&D; and commercialization." In response to China's announcement, Tie posted: "Welcome to the dawn of the biological arms race." The Future Outlook: Inevitable Genetic Modification "Biology is a double-edged sword – it can be used for good, to heal people, or it can be used for bad," Tie explains. "Stopping this research will only drive bad actors to do it secretively. There is no way to stop this. This is inevitable. The only way to proceed is to do it openly and transparently." Tie named her first human gene-editing company the Manhattan Project, drawing a parallel between the nucleus of the atom and the nucleus of the cell. "In the 20th century, we understood the nucleus of the atom very well, and we learned some very difficult lessons via weapons and wars," she says. "I don't want to see the same happen with the second nucleus." Despite her declared commitment to openness, much of Tie's work remains shrouded in secrecy. Her first company, the Manhattan Project, has since shut down due to what she calls a "fundamental mistake" in choosing a co-founder. She has since launched Origin Genomics, continuing her pursuit of genetic modification of embryos.

The Call to Cut Ties with Israel Nearly 5,000 staff, students, and honorary degree recipients from across Belgian universities are pushing for their institutions to sever all ties with Israel over its genocidal war on Gaza and attacks in the occupied West Bank. The Open Letter and Its Demands An open letter titled 'No Honour in Complicity' was published on Tuesday by the group of 4,700 signatories – including 1,100 professors and 50 honorary doctorate recipients – urging Belgian universities to 'terminate all institutional collaborations with Israeli institutions involved in violations of international law'. The group has four main demands: the termination of all existing collaborations with Israeli institutions and companies involved in violations of international law; a moratorium on new collaborations; pressure from universities on Belgian and European authorities to comply with international legal obligations; structural support for Palestinian higher education through scholarships, research programmes and institutional partnerships. The Impact of Israeli Actions The move comes as near-daily Israeli attacks in Gaza have killed more than 900 Palestinians and injured more than 2,700 others since an October 'ceasefire', according to Gaza's Ministry of Health, and as Israeli army raids and settler attacks have intensified across the occupied West Bank since the start of the genocidal war in Gaza. The Significance of the Academic Mobilisation The list of signatories includes Francesca Albanese, the United Nations special rapporteur on the occupied Palestinian territory; Amnesty International Secretary-General Agnes Callamard; climate justice activist Greta Thunberg; Nobel Prize-winning author JM Coetzee; and actor and writer Stephen Fry. The letter claimed the group represents more than 10 percent of the entire Belgian professoriate, making it one of the largest academic mobilisations in Belgian higher education. The Future Outlook The initiators place the Belgian appeal within a broader international movement of academic institutions, researchers and civil society organisations calling for institutional measures against Israeli apartheid and the destruction of Palestinian educational institutions.

The Hollywood Critique from a Master Filmmaker Quentin Tarantino has launched a scathing attack on contemporary Hollywood, describing it as "a flavourless sausage factory" in a recent article for Sight and Sound magazine. The renowned director, famous for films like Pulp Fiction and Kill Bill, expressed his disillusionment with modern cinema, stating that since the pandemic, he finds it almost impossible to enjoy new releases. A Director's Disillusionment with Modern Cinema In his candid assessment, Tarantino noted that "flaws, implausibilities, audience pandering, miscast performers or just plain stupid shit usually torpedoes every new movie coming out of the flavourless sausage factory that used to call itself Hollywood." He contrasted this with his experience of 1980s cinema, which he found forgivable because he "loved going to the movies," whereas today's films "inspire contempt in me than generosity." The Rare Exceptions in Contemporary Film Despite his harsh criticism, Tarantino did acknowledge a few recent films he enjoyed. He highlighted Joe Carnahan's "The Rip" (currently on Netflix), Steven Spielberg's "West Side Story," and Kevin Costner's "Horizon: An American Saga" Chapters 1 and 2 as examples of cinema that still holds his interest. However, he lamented that he has seen "nothing that really held me in its grip and swept me away to the magical land of enjoyment that I used to visit regularly." The Industry Implications of Tarantino's Critique Tarantino's criticism carries significant weight in the film industry, given his status as an acclaimed director whose films have grossed over $2.5 billion worldwide. His comments reflect growing concerns about formulaic storytelling, risk-averse production, and the prioritization of franchise films over original content in contemporary Hollywood. The director's preference for books over modern movies suggests a deeper cultural shift in how audiences are engaging with storytelling mediums. Tarantino's Future Projects and Hollywood Legacy While expressing disillusionment with current Hollywood output, Tarantino remains active in the entertainment industry. He is currently developing "The Popinjay Cavalier," a "swashbuckling" play scheduled to open in London's West End in 2027. His most recent film release was the 2019 hit "Once Upon a Time… in Hollywood," and a follow-up directed by David Fincher is currently in production. Notably, Tarantino scrapped plans for his supposed final film, "The Movie Critic," in 2024, leaving his legacy as a filmmaker still evolving.

The Passing of a Literary IconMarjane Satrapi, the French-Iranian artist, film-maker and graphic novelist whose acclaimed memoir Persepolis helped reshape international perceptions of Iran, has died at the age of 56. In a statement provided to French news agency AFP, relatives said she had "died of sadness" after the death of her husband, the Swedish producer Mattias Ripa, who passed away on 8 April last year.A Life of Art and ResistanceBorn in 1969 in Rasht, Iran, near the Caspian Sea, Satrapi was raised in Tehran by her father, an engineer, and her mother, a dress designer. As a teenager, she left Iran after her parents sent her to Europe to continue her education, hoping to spare her from the restrictions imposed under the Islamic Republic. She eventually settled in France, arriving in 1994 and later becoming a French citizen in 2006.Throughout her life, Satrapi was a vocal opponent of Iran's clerical establishment. In 2000 she published Persepolis, a comic book memoir that became an international publishing phenomenon. It told the story of a rebellious and outspoken young girl navigating the upheaval in Iran after the shah is overthrown in 1979 and the establishment of the Islamic Republic.The Impact of PersepolisThe memoir sold millions of copies, established Satrapi as one of the most widely read Iranian authors in the world, and its success challenged many western assumptions about Iranian society and culture. Satrapi later co-directed the animated film adaptation of Persepolis, which became an international hit and earned her a place in Oscar history as the first woman nominated for the Academy award for best animated feature.Satrapi has described how she initially had little expectation that Persepolis would reach publication. At the time, she was still an arts student in Strasbourg and had relatively limited professional experience in comics. "With Persepolis, I didn't even think I'd find a publisher," she said in a 2020 interview. "I thought I'd make 50 photocopies for my friends to read."A Voice for Iranian WomenSatrapi went on to direct five feature films, including Radioactive (2019), starring Rosamund Pike as the pioneering scientist Marie Curie. After leaving comics for years, in 2024, she returned to the medium, coordinating Woman, Life, Freedom, a collaborative graphic work bringing together 17 Iranian and international comic artists alongside academics and researchers. The book examined the protest movement that emerged after the death in custody of Mahsa Amini, a 22-year-old Kurdish-Iranian woman detained in 2022 for allegedly failing to comply with Iran's mandatory headscarf rules.Discussing the book, Satrapi said: "The only thing I can do is cultural work ... This book is a message to the Iranian people to say, listen, you are not alone."A Legacy of Freedom and ExpressionTributes have been paid to Satrapi from across French politics and culture following news of her death. President Emmanuel Macron said Satrapi was "a great artist who turned her Iranian childhood into a universal tale," adding: "With her childlike perspective, her irony, her tenderness, her inner demons, the author created a moving world with which readers identified."French journalist Tristane Banon paid tribute to Satrapi on X, writing: "Marjane ... you won't call me to wish me a happy birthday and 'celebrate those little cheeks that I adore'... and I can't get over it. You were freedom and determination. Courage too. One day, the Iranian people will be free, with you and as much as you."
