'Spot the difference' to help reveal Rosetta image secrets

Today, ESA and the Zooniverse launch Rosetta Zoo, a citizen science project that invites volunteers to engage in a cosmic game of "spot the difference." By browsing through pictures collected by ESA's Rosetta mission, you can help scientists figure out how a comet's surface evolves as it swings around the Sun.

Man who received landmark pig heart transplant died of pig virus, surgeon says

Self-propelled, endlessly programmable artificial cilia

For years, scientists have been attempting to engineer tiny, artificial cilia for miniature robotic systems that can perform complex motions, including bending, twisting, and reversing. Building these smaller-than-a-human-hair microstructures typically requires multi-step fabrication processes and varying stimuli to create the complex movements, limiting their wide-scale applications.

A motif perched within the Gilgameš Epic

Birds call forth a myriad of meanings in the Gilgameš Epic. Winged creatures convey abundance and revelry, enhance the narrative's soundscape, and foretell events in the story. In the article "Soundscapes, Portentous Calls, and Bird Symbolism in the Gilgameš Epic" published in the Journal of Near Eastern Studies, Adam E. Miglio employs an intertextual analysis to examine the epic poem's avian...

Named after Eta...

Self-propelled, endlessly programmable artificial cilia

Researchers have developed a single-material, single-stimuli microstructure that can outmaneuver even living cilia. These programmable, micron-scale structures could be used for a range of applications, including soft robotics, biocompatible medical devices, and even dynamic information encryption.
