How a Dirty Diaper Helped a KGB Colonel Escape the Soviet Union

19 October 2026 at 09:00
In November 1983, the Soviet Union came to believe that NATO might be preparing a nuclear attack. The trigger was a war game. The alliance’s annual exercise, Able Archer 83, ran from 7 to 11 November and rehearsed what would happen if a conflict in Europe escalated until nuclear weapons were released. It even simulated […]

Oleg Gordievski, el espía que escapó de la URSS gracias al pañal sucio de un bebé

19 October 2026 at 08:58
En noviembre de 1983 el mundo estuvo al borde de una guerra nuclear. La OTAN estaba llevando a cabo un ejercicio de simulación bélica, bautizado con el nombre de Able Archer 83 y que incluía el uso teórico de armas atómicas tras una escalada de tensión internacional, cuando el programa soviético de detección de ataques […]

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11138-7

Machine-learning-enabled atomistic simulations, spectroscopy, electrochemical data and quantum-chemical calculations reveal previously unstudied multi-lithium-ion complexes without bound anions, improving understanding of lithium-ion-battery functionality at the atomic level.

Parity-dependent coupling of molecular spin chains to a superconductor

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11117-y

Scanning tunnelling spectroscopy shows that the fractional spin-1/2 end states of molecular Haldane chains couple differently to a superconducting condensate depending on whether the chain contains an even or odd number of spin-1 triangulene units.

De novo design of cysteine proteases

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11143-w

Divergent genomic evolution in astrocytomas and oligodendrogliomas

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11150-x

Longitudinal genomic analyses in patients with astrocytoma or oligodendrioglioma suggest that these two types of tumour differ in the mechanisms by which they become resistant to treatment, with astrocytomas accumulating copy-number alterations and chromosomal instability markers but oligodendrogliomas acquiring new driver mutations.

Rh<sup>3+</sup> stabilized in KRh@MFI catalyses regioselective hydroformylation

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11136-9

DFT investigations combined with spectroscopic and catalytic studies of disrupted subnanometric Rh2O3 clusters show that Rh+ centres in a zeolite-based catalyst are blocked with N-containing molecules, whereas Rh3+ sites are stabilized, allowing hydroformylation reactions with enhanced regioselectivity and efficiency.

Targeted stimulation of motor cortex ensembles drives learned movements

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11174-3

Optogenetic stimulation of motor-cortex neuron ensembles shows that precisely timed activity in the primary motor cortex can generate learned neural patterns and movements, demonstrating an active role in skilled motor control.

Artificial intelligence-enabled clinical phenotyping of human brown fat

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11162-7

Artificial intelligence-enabled quantification and analyses of brown adipose tissue (BAT) activity uncover links between BAT and a healthier metabolic profile along with lower rates of psychiatric disease, and can identify pharmacologic agents that could be repurposed to activate this tissue in humans.

Wave coarsening drives time crystallization in mechatronic metamaterials

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11163-6

Wave coarsening in active elastic media is a phenomenon in which vibrations spontaneously increase in wavelength, period and amplitude before forming a globally synchronized time crystal.

Sexual dimorphism in epidermal stem cell dynamics

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11159-2

Long-term live imaging of adult mouse ear skin reveals sex-specific differences in the clonal dynamics of epidermal stem cells and transit-amplifying cells during homeostasis.

A microexon regulatory code reveals autism-linked genetic variation

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11119-w

A regulatory sequence code for neuronal microexons reveals genetic variants predicted to alter their splicing in individuals with autism.

Advancing subseasonal forecasting with machine learning

Nature, Published online: 14 October 2026; doi:10.1038/s41586-026-11126-x

The AI framework probabilistic bias correction is shown to correct weather forecast errors 2 to 6 weeks ahead and boost forecast skill, making it promising for improved extreme-weather prediction.

An abrupt shift towards a hotter and drier climate regime in the Western Eurasian Steppe

Nature Geoscience, Published online: 12 October 2026; doi:10.1038/s41561-026-02125-8

The Western Eurasian Steppe has undergone an abrupt and persistent transition to a hotter and drier summer climate that exceeds the range of natural variability, driven by external climate forcing and amplified by internal variability and land–atmosphere feedbacks, according to observations and Earth system model simulations.

All of Today’s European Monarchs are Descended From a Family You’ve Never Heard of: The Oldenburgs

15 October 2026 at 08:54
Most of us can rattle off Europe’s great royal houses: the Bourbons, the Habsburgs, the Plantagenets, the Stuarts, the Romanovs, the Windsors. Far fewer people have heard of the House of Oldenburg, yet few families have left a deeper or longer-lasting mark. Through a long chain of marriages, the Oldenburgs spread across the north of […]

Todos los actuales monarcas europeos descienden de una familia de la que nunca has oido hablar: los Oldemburgo

15 October 2026 at 08:53
A todos nos resultan familiares determinadas dinastías europeas; Borbón, Habsburgo, Avis, Plantagenet, Trastámara, Lancaster, Romanov, Bernadotte, Estuardo o Windsor, por citar sólo una pequeña parte. Pero es curioso que una de las que han dejado una huella más profunda y duradera no sea tan conocida; nos referimos a la Casa de Oldemburgo, que a través […]

Francis Halzen and IceCube: why neutrinos keep attracting Nobel prizes

8 October 2026 at 16:13

The 2026 Nobel Prize for Physics has gone to Francis Halzen for his “decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin”.

In this episode of the Physics World Weekly podcast I am joined by the University of Oxford neutrino physicist Kirsty Duffy and Physics World’s Matin Durrani to talk about this year’s prize. This is the fifth time a Nobel prize has been awarded for work on neutrinos, and we explore why physicists are so enamoured with these elusive particles.

This podcast is supported by American Elements, the world’s leading manufacturer of engineered and advanced materials. The company’s ability to scale laboratory breakthroughs to industrial production has contributed to many of the most significant technological advancements since 1990 – including LED lighting, smartphones, and electric vehicles.
