Energy¶
New catalyst reduces platinum use in hydrogen fuel cells by 75%¶
A reported breakthrough claiming a new catalyst cuts platinum use in hydrogen fuel cells by 75% while maintaining performance could not be verified, as the original source was inaccessible and no matching research was found.

Paleontology¶
Dinosaurs evolved to giant sizes but rarely to tiny forms¶
Research suggests dinosaurs' evolutionary constraint against miniaturization may have been caused partly by competition with early mammals.
