  "account": "Scientists have identified a previously unknown mechanism that influences high cholesterol, and developed a drug candidate that can effectively block it. This discovery, highlighted by ScienceDaily, demonstrates how structural biology can rapidly translate fundamental findings into concrete therapeutic strategies. However, the press releases rarely mention the crucial detail of molecular geometry: a signaling pathway described in a paragraph exists physically in just a few angstroms - a pocket, helices, a ligand that fits or not. When targeting a \"hidden driver\" of lipid metabolism, the operational question is not \"which protein?\" but \"where exactly, and with which form?\" Enter NexoPeek, a virtual reality molecular laboratory developed by Seven Sportz for Meta Quest headsets. Instead of viewing macromolecules on flat screens, users enter 3D structures - proteins, ligands, nucleic acids - at human scale, with or without VR controllers. They walk around a binding pocket, grasp it, and scale it. The application features two tracks: guided tours and a professional PDB viewer. Guided tours include twelve narrated visits, organized into six thematic pillars, based on real structures from the Protein Data Bank - biotechnology foundations, life's fundamentals (hemoglobin, oxygen binding, ATP production), pathways and interactions (glycolysis, trypsin), drug action (aspirin inhibiting COX enzymes, caffeine, penicillin), genetic technologies (CRISPR-Cas9, central dogma, Yamanaka factors), and green biotechnologies (plastic enzymes - engineering). For students encountering a protein for the first time, this is not just another animation: it's a spatial memory. The second track is a professional PDB viewer for research, medicinal chemistry, and structural biology. NexoPeek becomes a workstation connected to online databases such as RCSB PDB, UniProtKB, AlphaFold DB, SWISS-MODEL, and PDBe, allowing intelligent search and multi-base routing. It also enables local ingestion of .pdb, .cif, .mol2, .gro, .xyz, .dx, .xtc, .py files, with overlay of electrostatic field maps, custom binding definitions, and electron density volumes. High-quality publication graphics include cartoon, ball-and-stick, spacefill CPK, molecular surface, heatmap B-factor, or tube trace representations, all accessible with a single tap from six Mol* presets. Fine-grained sequence/chain control allows scrolling of amino acid sequences by chain, \"pasta\" residues projecting a 3D halo, atom pinning, and string isolation. Embedded analytics include drugable pocket prediction (PrankWeb / P2Rank in the cloud, or integrated offline engine), structural alignment via integrated Foldseek pipeline, ligand inspector with 3D retrieval from PubChem, and angstrom distance calculation via atom selection. The mixed reality / passthrough feature allows the structure to float in your real room while the side menu remains operational. For this cholesterol story, the importance lies in the dual educational/professional approach. A teacher can project glycolysis in a classroom one day, and a structural biologist inspect a binding pocket the next - same headset, same application, shared visual vocabulary. For laboratories recruiting students, this reduces the transition from \"I saw a diagram\" to \"I know where to look.\" NexoPeek is educational software and a research visualization tool, not a medical opinion, diagnosis, or treatment. Always verify results against primary literature and validated methods before acting.",
  "summary": "Un « pilote caché » du cholestérol : pourquoi la poche compte plus que le schéma Les scientifiques viennent de lever le voile sur un mécanisme insoupçonné : les régimes riches en cholestérol activent une voie qui neutralise les défenses naturelles de l'organisme contre le LDL. Bloquer cette voie fait dramatiquement chuter le cholestérol nocif chez la souris, et un candidat médicament ciblant ce…",
