The same RIS score shown in the table above, evaluated at each point in history — a citation-weighted view of what mattered when, not just how many papers came out that year.
Watch uranium spike with the bomb, silicon rise with the chip, and the rare-earths climb with modern magnets.
Showing each element's three strongest connections. Personal opens the slider and the whole 118-element graph.
A heatmap of what science is paying attention to — right now. Every tile glows with real research activity, scored from live publication and citation data. A market heatmap, but for the periodic table.
Every tile here — its full history included — is free for anyone, no account needed. Create a free account to bookmark the papers you find and keep your own shortlist of elements, instead of starting over on every visit.
Every element's name, symbol, and known compounds are searched across the scientific literature on a recurring cycle.
Matches are linked back to the elements they belong to, building a live index of research by element.
Each element's momentum is scored from how much is being published about it, and how much of that work matters.
A snapshot publishes on a regular cadence — what you see here is never a live query.
Most scholarly databases don't organize papers by chemical element — we do. That's what makes this index possible.
