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.

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.

Russian mathematics is losing ground, scientists are leaving, and international ties are fraying — yet the government’s new Concept for the Development of Mathematical Sciences through 2036 presents all of this almost as a force of nature. The number of researchers has “declined,” access to global science has been “restricted,” and the country’s competitive edge is at risk of being “lost.” Who restricted what, where the scientists went, and why Russia is losing influence, the document hardly explains. T-invariant read the Concept and found a striking picture: global mathematics appears in it as something like a warehouse to which access must be “ensured” — preferably along with additional funding.

Russian-American Science Association strongly condemns the decision of the Russian authorities to designate our colleague Tatiana Tatarinova, a distinguished bioinformatics scholar and professor at the University of La Verne, as a “foreign agent.”

Since the start of the full-scale war, Russian science has lost key ties with Western universities and research centers. Yet four years of sanctions have not led to a collapse. Instead, Russia rapidly reoriented toward China, other parts of Asia, and the Middle East, while the Kremlin firmly integrated higher education into its system of military priorities. These are the conclusions reached by Olga Orlova, head of T-invariant, in her report Transformation of Science and Education in Russia under Sanctions 2022–2026, which examines changes in Russian academia over the past four years.

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 29, the Moscow City Court is set to hand down its verdict against Darya Shipacheva, author of books and podcasts about chronic pain. The prosecution of this science journalist and feminist activist illustrates a new pattern in how Russia’s repressive machine operates. Treason cases involving money transfers to Ukraine — like those involving donations to Alexei Navalny’s Anti-Corruption Foundation (ACF) — have been fast-tracked: closing arguments in cases seeking 12-year sentences now take just one hearing, lasting only an hour and a half. And online stalking (in Shipacheva’s case, by activists from the misogynistic Men’s State movement) can be enough to trigger a criminal case, including under repressive charges like treason.

In June 2026, the mathematician Misha Verbitsky ended up in an Armenian jail, caught in the automatic machinery of intergovernmental agreements that Russia has pressed into service for political persecution. Starting from that story of police and politics, his conversation with T-invariant editor Alexander Sergeev turns steadily more philosophical. How is polarization destroying scientific unity? Why doesn’t a powerful intellect protect anyone from insane ideas? And how does the “intelligent mold” of AI call into question both human cognitive exceptionalism and the value of mathematical truth, returning us to first principles — the joy of communication and pure aesthetics?

In 1993, Marina Bykova became the youngest Doctor of Sciences in the humanities in Russia. Today she is a professor at an American university and editor-in-chief of the journal Studies in East European Thought. Her professional life has been devoted to building and sustaining dialogue between the Russian philosophical tradition and the international academic community. In an interview with T-invariant, Marina Bykova reflects on why Russian academia has been paralyzed by fear, how the cultural project of the “Russian World” turned into a political ideology, and what happens to philosophy when it loses its autonomy.
