      • When a Better Immune Response Is Bad

        Increased signaling of plasmacytoid dendritic cells through TLR7 and TLR8, triggered by HIV-1–derived ligands, underlies women’s increased susceptibility to progression to AIDs.

      • Signals from a Sunken Ship

        The G protein–coupled receptor for thyroid-stimulating hormone continues to couple to adenylyl cyclase and generate cyclic AMP after it is internalized.

      • SNORKELing for Rice

        Two ethylene-responsive genes allow rice to adapt to flooding.

      • When Repair Is Suicide

        Persistent elevated calcium in apoptotic cells triggers fusion of lysosomes with the plasma membrane, producing the membrane-associated hallmarks of programmed cell death.

      • Minimizing Plasticity

        Modulation of calcium buffering and extrusion may provide a mechanism for regulating long-term potentiation.

      • Making Memories Last

        Pharmacological and biochemical analyses reveal that dopamine determines the duration of fear memory storage.

      • Going Retro

        The short legs that characterize certain dog breeds are associated with a gene that arose recently by RNA-based gene duplication.
