Scientists have made a groundbreaking discovery, identifying a distinct 'neural fingerprint' produced by psychedelic drugs in the human brain when users experience their mind-altering effects.This breakthrough finding emerged from a comprehensive study that combined 11 brain imaging datasets from around the world, involving over 500 brain scans from 267 people in five countries. The research focused on five psychedelic substances: LSD, psilocybin, DMT, mescaline, and ayahuasca.The study revealed that these substances have a shared impact on the brain's behavior, dissolving the usual hierarchy of brain systems and flattening the hierarchy, which may underlie the raw access to one's own consciousness that some people describe during psychedelic experiences.Dr. Danilo Bzdok, a senior author on the study from McGill University in Montreal, Canada, explained that all five drugs change brain function in common ways, despite some differences in how they alter brain activity. The most striking effect was stronger communication between brain networks that engage in higher-level thinking and more primitive networks linked to vision and sensation.The research, published in Nature Medicine, provides a solid foundation for psychedelic research, which is crucial if these drugs are to become widespread therapies for mental health conditions such as depression, schizophrenia, and post-traumatic stress disorder.Dr. Emmanuel Stamatakis, a senior co-author on the study from the University of Cambridge, emphasized the importance of large-scale, coordinated evidence in the field of psychedelic research, which is moving quickly and needs to mature responsibly.

When billionaire hedge‑fund manager Chris Rokos announced a £190 million contribution to the University of Cambridge, the move instantly became the largest single donation to any UK university in modern history. The funds will establish a new “school of government” aimed at bridging policy, science and emerging technologies. Rokos, a 55‑year‑old Oxford graduate, has amassed an estimated £2.6 billion fortune, primarily through his firm Rokos Capital Management (RCM), which he founded in 2015 after a high‑profile stint at Brevan Howard. RCM now oversees **over £22 billion** in assets, employs roughly 350 staff, and operates from offices in London, New York, Singapore and Abu Dhabi. In the most recent fiscal year ending March, Rokos paid himself nearly £500 million, according to Companies House filings, reflecting the firm’s strong performance amid volatile markets. Beyond finance, Rokos has kept a remarkably low public profile. He famously declined to provide a photograph when launching a £500 million fund in 2007, and he has avoided media attention despite owning one of England’s most expensive private residences. The £175 million refurbishment of the Grade I‑listed Tottenham House in Wiltshire – featuring a tennis pavilion, private cinema, basement squash court and a proposed “subterranean family link” to a pool house – has drawn local council scrutiny but stands as a tangible testament to his wealth. Rokos’s career trajectory began in banking at UBS and Goldman Sachs, moving to Credit Suisse where he was recruited by Alan Howard. He later joined the founding team of Brevan Howard in 2002, generating roughly $4 billion (≈£3 billion) in investor profits and about £600 million for himself before departing in 2012. His philanthropic philosophy emphasizes diversity of thought. In a video released by Cambridge, Rokos warned that a school populated only by “centrist, socially liberal” voices would be a failure, insisting on a broad spectrum of intellectual viewpoints. Earlier this year, RCM’s exploratory talks to bring former UK business secretary Peter Mandelson onto its advisory board collapsed after revelations about Mandelson’s connections to the late Jeffrey Epstein. Rokos also ranks among the UK’s biggest taxpayers and maintains a family office in Mayfair. A lingering legal dispute over a five‑year non‑compete clause with a former employer was settled out of court, clearing the way for his current venture. Overall, the record‑breaking Cambridge donation not only reshapes the university’s academic landscape but also underscores how hedge‑fund wealth is increasingly channeled into high‑impact philanthropy, blurring the lines between finance, education and public policy.

British hedge‑fund billionaire Chris Rokos has announced a £190 million endowment to the University of Cambridge to create a new, eponymous school of government. The pledge, comprising an initial £130 million and a further commitment of up to £60 million that the university will match, is believed to be the largest single donation ever made to a UK university. The Rokos School of Government is slated to open in temporary facilities this autumn, offering PhD and master’s programmes focused on public policy, leadership and governance. In the longer term it will relocate to a purpose‑built campus within Cambridge’s West Innovation District, positioning itself as a direct rival to Oxford’s Blavatnik School of Government, which was launched in 2010 with a £75 million gift. Rokos, 55, rose from a state primary school to a scholarship at Eton and a mathematics degree at Oxford before co‑founding the hedge fund Brevan Howard and later establishing Rokos Capital Management, which now employs over 350 staff. He is listed on the Sunday Times Rich List with an estimated net worth of £2.6 billion and is among the UK’s biggest taxpayers. Speaking about the donation, Rokos said, "I was fortunate to be given an education that transformed my life, and I would like to give something back to Britain. My hope is that, in time, the influence of the Rokos School of Government across the world becomes an important element of that soft power, which has been a great asset to the UK." University officials framed the new school as a response to “growing turbulence in domestic and international politics, increasing polarisation of political opinion, and long‑term structural changes in the economy.” The institution aims to provide a “unique forum for radical and remarkable thinking,” leveraging Cambridge’s tradition of scientific innovation and interdisciplinary collaboration. Vice‑chancellor Prof. Deborah Prentice added, "Tackling the enormous challenges facing our world requires radical new ways of thinking and approaches to leadership. Cambridge’s strengths across all disciplines and its convening power make it uniquely positioned to drive this innovation. Thanks to Chris’s generous support, the Rokos School will become a place where current and future leaders, together with experts from across our institution, generate the insights and solutions needed for a rapidly changing world." The school’s establishment also reflects a broader trend of private wealth shaping public‑policy education in the UK, echoing similar high‑profile gifts such as Leonard Blavatnik’s £75 million donation to Oxford. By creating a dedicated hub for governance studies, Rokos hopes to cement Cambridge’s role as a training ground for future world leaders and to reinforce Britain’s international influence. Rokos Capital Management recently made headlines when talks to appoint former UK ambassador Peter Mandelson as an adviser were terminated following renewed scrutiny of the Epstein scandal, underscoring the complex interplay between finance, politics and public perception. The £190 million endowment not only marks a milestone for UK higher‑education philanthropy but also signals a strategic investment in the development of policy expertise that could shape global governance for decades to come.

A leading Rembrandt scholar, Gary Schwartz, has concluded that a portrait titled 'Old Man with a Gold Chain' and dated to the early 1630s is, in fact, an authentic work by the 17th-century Dutch master. The painting, which has been on loan from Sir Francis Newman, a Cambridge-based entrepreneur, has been reunited with its counterpart at the Art Institute of Chicago.Each of the paintings depicts an older man wearing a gold chain and a plumed hat. For almost four centuries, the two portraits have been separated, with the Chicago version considered the undisputed original. The Newman portrait, slightly smaller and painted on canvas, was previously labelled as a 'copy' by an artist in Rembrandt's workshop.However, Schwartz's research suggests that both paintings are by Rembrandt. He argues that the quality of the brushwork and the practice of Dutch artists creating replicas of their own paintings support this conclusion. In 1699, a French contemporary of Rembrandt noted that it was common for Dutch artists to repeat their works.X-ray and infrared imaging of the Chicago picture revealed underdrawing and adjustments to the man's costume, which were absent from the Newman canvas. This led Schwartz to conclude that the Newman painting was not a workshop reproduction but an original work by Rembrandt.The Hamilton Kerr Institute at the University of Cambridge found that the UK version's canvas and colour pigments matched those used by Rembrandt and his studio. If confirmed as a Rembrandt, the painting will go to a museum, according to Newman.
