Advanced Science, EarlyView.The flavonoid compound LW‐213 exerts its antitumor effects through a novel mechanism involving lysosomal‐ER calcium regulation. Specifically, LW‐213 binds to LIMP2, which induces perinuclear clustering of lysosomes and facilitates calcium‐mediated lysosome‐ER interactions.

Flutter of a Low-Aspect-Ratio Rectangular Wing [PDF]
A flutter test of a low-aspect-ratio rectangular wing was conducted in the Langley Transonic Dynamics Tunnel (TDT). The model used in this flutter test consisted of a rigid wing mounted to the wind-tunnel wall by a flexible, rectangular beam.

Advanced Science, EarlyView.This study identifies α‐Hederin as a potent dual JAK1/JAK2 inhibitor that blocks STAT3 activation in ovarian cancer. By disrupting STAT3‐driven transcriptional programs, α‐Hederin suppresses tumor proliferation, invasion, and EMT, while enhancing cisplatin efficacy and overcoming chemoresistance.

AEROELASTIC FLUTTER ANALYSIS OF SUPERSONIC WING WITH MULTIPLE EXTERNAL STORES
International Islamic University Malaysia Engineering Journal, 2014 : Flutter may be considered to be one of the most dangerous aeroelastic failure phenomenon. The flutter characteristic differs for each aircraft type, and depends on the wing geometry as well as its operational region of subsonic, transonic or supersonic

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.

Passive control of wing/store flutter [PDF]
Results are presented for a passive flutter suppression approach known as the decoupler pylon. The decoupler pylon dynamically isolates the wing from store pitch inertia effects by means of soft spring/damper elements assisted by a low frequency feedback
