The “forced digital detox” delivered by Ukraine’s Armed Forces has hit the most profitable part of Yandex’s business: search and AI. The long-term fallout from the attacks on the company’s data centers has yet to be assessed, but supercomputing experts consulted by T-invariant are confident that all three of its supercomputers — Chervonenkis, Lyapunov, and Galushkin — were badly damaged by fire and smoke. Soot and ash may have reached the machines’ microelectronics through their direct free-cooling systems, which use outside air. In the best case, cleaning them will take many months; in the worst, Yandex will have to buy new, extremely scarce NVIDIA chips or their equivalents, which will take years. The company owns Russia’s best supercomputers, which, according to its financial reports, had recently become key drivers of its growth. On the eve of the full-scale invasion of Ukraine, Chervonenkis ranked 19th on the global Top500 list of supercomputers, competing with leading systems from the US, China, Japan, and Germany. After the Ukrainian drone strikes, Russia risks falling behind Kazakhstan in the performance of its top supercomputers as early as November.

In accordance with the Regulations of the George Gamow® Award, established by the Russian American Science Association (RASA-America) in honor of the distinguished Russian American physicist Professor Georgy Antonovich Gamow (1904–1968), and to recognize members of the Russian-speaking scientific diaspora for outstanding achievements widely acknowledged by the scientific community, the 2026 G.A. Gamow Prize is awarded to Natalia Berloff and Mikhail N. Epstein.

Sofia Rosenfeld has spent her life studying Arctic birds: traveling on expeditions to the Far North, following flocks of geese in a seaplane, and fighting to protect rare species. Now one of Russia’s leading ornithologists, a Doctor of Sciences in Biology, has been sentenced to three and a half years in a penal colony — for two 1,000-ruble donations to the Anti-Corruption Foundation (FBK). Rosenfeld partially admitted guilt: she explained that she had been unable to cancel the recurring payments because she was on an expedition without communications. T-invariant explains why the scientist refused to leave Russia, how the trial unfolded, and what Russian science stands to lose.

September brought a flurry of developments in the use of AI in mathematics. The biggest, though far from the only one, was OpenAI’s publication of a solution to the Millennium Prize Problem concerning the Navier–Stokes equations. The announcement set off a heated debate about AI’s impact on the future of science. T-invariant looks at OpenAI’s result and the events that followed it (spoiler: mathematics has changed, and it was AI that changed it).

The Supreme Court of the Komi Republic has sentenced philosopher Nikolay Zyuzev to seven years in a strict-regime penal colony on treason charges. Zyuzev, who holds both Russian and Canadian citizenship, is one of the best-known scholars of the legacy of the Russian-American sociologist Pitirim Sorokin. He left Russia after the war began, but in the summer of 2025 he returned to his native village in Komi [a republic in northwestern Russia — T-invariant], where he was arrested. According to the FSB, the scholar was training leaders of national liberation movements among Russia’s small Indigenous peoples and receiving funding for his project from foreign organizations. T-invariant looks at what Zyuzev worked on, why he kept coming back to Russia, and what his friends and colleagues make of the treason charges.

Research institutes and universities across Russia are keeping blacklists of their own staff. T-invariant has identified two patterns of pressure on scientists and faculty: they are summoned for “conversations” with FSB officers, or they are left without work when an expiring contract is quietly not renewed.

Renowned American legal scholar Austin Sarat, a founder of the humanistic study of law, on the responsibility of public intellectuals in the United States, the bracing “slap in the face” Trump dealt to universities, and the path forward in defending academic freedom and democracy.

T-invariant is publishing its latest regular report, Chronicle of the Persecution of Scientists No. 36, dated August 31, 2026. Azat Miftakhov has published a paper in the French quarterly La Revue de la filière mathématiques (June–August 2026). The paper was written at the suggestion of French mathematician Bernard Randé, a member of the journal’s editorial board and of the international association Solidarité FreeAzat. Miftakhov completed the work while held in prison in Dimitrovgrad.

Andrei Klepach — one of Russia’s leading economists and a high-ranking economic official of the Vladimir Putin era — has published several academic works over the past six years that are packed with cosmist imagery. His drift into “energy-information cosmism” went unnoticed until Klepach was fired as chief economist of the state corporation VEB.RF — after he publicly offered a bleak assessment of Russia’s ability to compete with the West and with Ukraine. T-invariant traced the economist’s academic evolution into a cosmist and looked into the background of his mentor on the road “toward a cosmoplanetary civilization.” It also turned out that, even after Klepach’s dismissal, VEB.RF has no shortage of people developing alternative “theories of everything”: the “wave hypothesis of life,” the idea of a “Fifth Russia,” and a “noosphere economy.”

On July 23, the U.S. Department of Defense published a new list of organizations it considers a potential threat to U.S. national security. The list includes Moscow State University (MSU), Bauman Moscow State Technical University, the Higher School of Economics (HSE), Ural Federal University, and several other Russian universities and research institutes. American scholars and universities receiving Pentagon funding are advised to terminate cooperation with these institutions. T-invariant examines how this new list differs from sanctions laws and what consequences it may bear for Russian and American science.

Exactly 35 years ago, on August 21, 1991, the coup attempt by the self-proclaimed State Committee on the State of Emergency collapsed. The Soviet Union itself had four more months to live, but after those three days in August, a completely different life began for millions of Soviet citizens. The changes touched everyone, but scientists were among those whose old lives fell apart especially fast — and on the ruins, new ones began to take shape. Institutes were left without money or staff, and entire fields of research lost their funding. Yet at the same time, the borders opened, and it became possible to work at universities and research centers abroad. Some left for a few months and never came back; others emigrated right away. How did these scientists discover the world of Western science? What did they have to go through? What did it cost them? And why did a temporary departure turn out to be permanent for so many of them? T-invariant presents the stories of how they left and the new lives they built.

While Slovak politicians calmly keep their academic degrees for copied theses thanks to convenient loopholes in the law, far less visible violations are taking place inside the universities themselves. Dozens of scholars appear to be linked to purchased authorship, data manipulation, and publications in predatory journals. The Plagiat-Navigator project tried to determine how deeply academic fraud has penetrated Slovak science.
