Advanced Science, EarlyView.This study integrates dual‐reporter genetics, imaging flow cytometry, and single‐cell sequencing to characterize rare bihormonal cells in mouse and human pancreatic islets. Gcg⁺Ins⁺ cells resemble α‐cells rather than transitional states. Cross‐species gene network analysis refines islet cell taxonomy and reveals human‐specific δ‐cell subtypes ...

A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis
Advanced Science, EarlyView.Magnetotactic bacteria align with Earth's magnetic field, helping them migrate toward low‐oxygen environments. This study reveals how Magnetospirillum gryphiswaldense uses a specialized flavin adenine dinucleotide (FAD)‐dependent chemoreceptor, composed of two interacting proteins, for precise navigation in oxygen gradients.

A Machine‐Learning Approach Identifies Rejuvenating Interventions in the Human Brain
Advanced Science, EarlyView.Rising life expectancy increases the incidence of age‐related neurodegeneration. Reverting brain aging through effective rejuvenation strategies constitutes a promising strategy to counteract these disorders and restore brain function. This study uses a brain‐specific transcriptional aging clock to screen over 43 000 perturbation profiles, identifying ...

Recurrence and non-uniformity of bracket polynomials
, 2014 A bracket polynomial on the integers is a function formed using the operations of addition, multiplication and taking fractional parts. For a fairly large class of bracket polynomials we show that if p is a bracket polynomial of degree k-1 on [N] then ...
