Malva: a Google-like RNA search across millions of cells in seconds

Malva is a Google‑like RNA search engine that indexes over 140 TB of public single‑cell and spatial transcriptomics data, enabling rapid, sequence‑based queries across millions of cells without downloading raw data or using a reference genome; it can reveal mutations, RNA isoforms, pathogens and more in seconds to minutes, potentially accelerating cancer and infection research, though it currently requires exact 24‑nucleotide matches and ongoing validation.
