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.

Tumor Extracellular Vesicles Aggravate Mitochondrial Damage in Myocardial Ischemia/Reperfusion Injury

Advanced Science, EarlyView.
This study reveals a novel mechanistic connection between cancer and ischemia/reperfusion (I/R)‐induced cardiac injury. The meta‐analysis demonstrates significantly higher incidence ratios of both all‐cause mortality and cardiovascular mortality in cancer patients undergoing percutaneous coronary intervention (PCI) compared to non‐cancer patients.

Distributed Temporal Coding of Visual Memory Categories in Human Hippocampal Neurons Revealed by an Interpretable Decoding Model

Advanced Science, EarlyView.
This study examines how the human hippocampus encodes visual memory categories. By decoding spiking activity from CA3 and CA1 neurons using an interpretable model, it reveals that category‐specific representations emerge from distributed temporal coding.

Bacteria Optimize Tumble Bias to Strategically Navigate Surface Constraints

Advanced Science, EarlyView.
The study investigates how Escherichia coli optimizes tumble bias (TB) to navigate surface constraints effectively. Using single‐cell tracking and modeling, it reveals that bacterial surface residence time decreases with increasing TB, stabilizing near the wild‐type mean TB (≈0.25), where surface diffusivity peaks.
