Scientists Discover Hidden Genetic Switches That Could Unlock Human Hibernation

Altered protein synthesis remodels the aging brain proteome. Age-related mRNA and protein changes are decoupled. Ribosome profiling reveals increased translation elongation pausing, occurring preferentially at codons encoding for basic residues. Ribosome pausing contributes to protein-transcript decoupling and is associated with a depletion in RNA and DNA binding proteins. These changes also contribute to protein misfolding and insolubility, linking protein synthesis defects to other aging hallmarks. PTMs, posttranslational modifications. Credit: Science (2025).

Scientists Discover Why Our Brains Age and the Answer Is Hidden in a Tiny Fish

For each session, participants were required to pedal up to a speed of 80 rpm. The adaptive, motorized bike assisted them in attaining that level but also added and reduced resistance depending on the rider's effort. Researchers believe this push-and-pull mechanism is beneficial for treating Parkinson's symptoms. Credit: Cleveland FES Center

(a) Localized electron in a polar liquid. The scheme shows the probability density of a localized electron (contour) in an environment of solvent molecules with an electric dipole moment. (b) Longitudinal excitation of the spherical molecular cloud around a localized electron. The displacements of molecules in radial direction change the nanometer diameter of the molecular cloud. (c) Scheme of a transversal excitation of the liquid on a macroscopic length scale, which exceeds the diameter of the molecular cloud by far. Credit: MBI: T. Elsaesser / M. Woerner

Cells express a novel ShortStop-predicted microprotein (green), with cell nuclei stained blue. The pattern suggests microproteins are localized either in endosomes, which are organelles responsible for sorting and transporting cellular cargo, or in lysosomes, which are organelles that collect and remove cellular waste.

Typical behavior of leopard seal vocalizations—the male will sing a sequence of sounds underwater before returning to the surface to breathe (represented by a "Z") and repeats this cycle for hours at a time. The sequence of sounds is then converted to a symbolic code (Microsoft PowerPoint Version 2505). Credit: Scientific Reports (2025). DOI: 10.1038/s41598-025-11008-8
