A Pore That Folds Shut: How a Selective Inhibitor Silences a Cardiac Potassium Channel
Every heartbeat depends on a precisely timed exchange of ions across cardiac cell membranes, and among the proteins orchestrating this process the potassium channel KCNQ1 plays a…

A Dial, Not a Switch: How Phosphorylation Tunes the Grip of a Splicing Factor on RNA
Every human gene is transcribed into a precursor RNA that must be edited before translation, and among the proteins that orchestrate this editing, known as splicing, SRSF1…

Inside the Parasite’s Splicing Machine: Cryo-EM Captures Trans-Splicing in Action
In nearly all eukaryotes, the messenger RNAs that carry genetic instructions must be edited before they can be translated into proteins, a task entrusted to the spliceosome, a…

An Enzyme That Works Near the Boiling Point: Nitrogen Fixation Caught at Near-Atomic Resolution
For more than a century, the industrial synthesis of ammonia has depended on the Haber–Bosch process, which forces nitrogen and hydrogen together at several hundred atmospheres…

Prying STING Open: How an Approved Drug Marks an Inflammatory Protein for Destruction
Aging is accompanied by a smoldering, chronic inflammation, and one of its suspected drivers is STING, a protein that helps cells respond to DNA where it should not be. In this…

Eight Letters Instead of Four: A Bacterial Enzyme Reads Synthetic DNA
All life on Earth writes its genetic information with the same four chemical letters: A, T, C and G. For decades, synthetic biologists have asked whether that alphabet could be…

A Phage’s “Loose Cannon”: How One Enzyme Disarms Bacterial Immunity
The bacteriophage T7, a virus that infects Escherichia coli , has long been a workhorse of molecular biology, yet a study published in August 2026 in Nature reveals that one of…

A Sharper Cut: How Silver Nanoparticles Could Rewrite the Rules of DNA Assembly
For seventy years, molecular biologists have relied on restriction enzymes to cut DNA into pieces that can be stitched back together, gene by gene. These proteins are picky: each…

ESCRT-III: How Cell-Division Machinery Learned to Protect DNA
ESCRT-III is, by any conventional account, a specialist in membranes rather than nucleic acids. A membrane-remodeling complex , it is best known for sealing the nuclear envelope…

FANCJ and the DNA Knots It Unties: A Structural Blueprint for a Cancer-Linked Helicase
Guanine-rich DNA can fold back on itself into four-stranded knots called G-quadruplexes, or G4s — structures that help regulate gene expression and telomere biology but that stall…

GPR84 and the Anatomy of Bias: A Structural Blueprint for Safer Anti-Inflammatory Drugs
GPR84 belongs to a peculiar category of cell-surface receptors: it is an orphan G protein–coupled receptor (GPCR), meaning that although it is known to respond to medium-chain…

An Ancient Alarm: Bacterial Schlafen Proteins Reveal a Deep Evolutionary Root for Antiviral Immunity
In mammalian cells, the Schlafen family of enzymes is known for an unusually drastic antiviral defense: when a virus invades, certain Schlafen nucleases shut down protein…
