These seven standout science TikToks of 2025 span mind-bending experiments and lighthearted explainers. Highlights include a retinal experiment reporting a novel color called “olo,” Greenland ice-core reporting, and a clear explainer of the Nobel-winning chemistry behind metal-organic frameworks (MOFs). Reporting also covered a newly identified blood type (bringing known types to 48) and an eerie piece on neurons from a deceased composer producing music. Lighter clips—like a tutorial for the scientifically perfect egg—rounded out the most-watched videos.
Seven Science TikToks You Should Watch Now — From a New Color to Greenland Ice Cores
From eye-opening discoveries to playful explainers, these seven science TikToks were among our most watched and shared clips of 2025. Together they showcase how short-form video can make complex science vivid, surprising and accessible.
A Novel Color Sensation: One headline-grabbing piece explored the limits of human perception. Researchers reported that by directing lasers to stimulate only the green cone cells in volunteers’ retinas, participants described experiencing a previously unreported color, dubbed “olo.” The team characterizes the sensation as a teal-like hue outside typical color categories, suggesting new insights into how our visual system constructs color.
Into the Ice: Chief multimedia editor Jeffery DelViscio traveled to Greenland to film inside an underground research facility. There he documented scientists drilling deep ice cores—stratified records that preserve thousands of years of climate history, layer by layer.
Ig Nobel Coverage: This year we began collaborating with science communicator Tom Lum to cover the Ig Nobel Prizes, the tongue-in-cheek awards that celebrate research that first makes people laugh and then think.
Nobel Prize Explainers: We also broke down each of the year’s three science Nobel Prizes. Senior multimedia editor Kelso Harper explained the Nobel Prize in Chemistry-winning work on metal-organic frameworks (MOFs)—porous materials with major implications for energy, storage and environmental applications. (Fun fact: Harper once worked in a MOF lab as a student.)
Emerging Biology Stories: Our reporting covered a newly reported human blood type, bringing the current tally of known blood types to 48, and an eerie neuroscience piece: associate editor Allison Parshall reported on a deceased composer whose neurons, cultured from his blood, continue to produce activity linked to musical patterns.
Fun With Food Science: Not all clips were solemn. Some of our most popular videos embraced whimsy, including a methodical deep dive into cooking the scientifically perfect egg—tedious to execute, but delicious and demonstrative of chemistry in the kitchen.
