Genome accessibility reveals disease risk that gene expression misses

Nature, Published online: 07 October 2026; doi:10.1038/d41586-026-03072-5

Most disease-associated genetic alterations do not affect the genes themselves, but instead change how strongly they are expressed, often by modifying genome accessibility. Gene expression and accessibility have now been analysed simultaneously in 10 million immune cells from 1,108 people, linking disease-associated changes in accessibility to gene expression.

An early predecessor to mammals could swim, suckle and swallow

Nature, Published online: 07 October 2026; doi:10.1038/d41586-026-03069-0

A fossil of an early ancestor of mammals from the Jurassic period reveals a mammal-like throat passage (pharynx) and throat bones (hyoids). It fills a gap in our knowledge about throat features in the animals from which modern mammals evolved their ability to swallow as adults and suckle milk as babies.

How to control where semiconductor crystals start growing

Nature, Published online: 07 October 2026; doi:10.1038/d41586-026-02934-2

Semiconductor crystals grow from tiny nuclei, but the position of these nuclei is difficult to control precisely and can affect the crystal’s properties. An approach using ‘etching flux’ has now been developed that constrains the position at which a nucleus forms, enabling spatially programmable growth of large single crystals of semiconducting material.

Observation of relativistic bond weakening in seaborgium hexacarbonyl

Nature, Published online: 07 October 2026; doi:10.1038/s41586-026-11105-2

Gas chromatography analysis of compounds formed by the superheavy element seaborgium shows that the hexacarbonyl complex Sg(CO)6 exhibits lower first bond dissociation energy than the lighter chemical homologue W(CO)6, owing to relativistic bond weakening effects.

RNA catalysis emerges from dynamic structural ensembles

Nature, Published online: 07 October 2026; doi:10.1038/s41586-026-11140-z

RNase P RNA forms shifting active and inactive conformers whose catalytic activity depends on Mg2+-driven tertiary-interaction dynamics, which are modulated by binding of accessory proteins.
