Rotating gas core collapsing and forming a central star
This still from a STARFORGE Project simulation depicts a rotating gas core collapsing and forming a central star that launches bipolar jets along its poles as it feeds on gas from the surrounding disk. The jets entrain gas away from the core, limiting the amount that the star can ultimately ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

Structured multi-part nanocrystals with super light-emitting properties
Researchers combined perovskite nanocubes -- tiny crystals with useful electrical or optical properties -- with spherical nanoparticles to form a regular repeating structure called a superlattice. Some of these structures displayed superfluorescence -- a burst of photons. [Research supported by ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

Nanoparticles make cement smarter -- and concrete tougher. Learn how at NSF's The Discovery Files.
NSF-funded engineers at Northwestern University are developing materials resilient enough to weather the forces of nature. This includes introducing nanoparticles into the manufacture of cement, making it smarter, more durable, tougher, and highly functional. They are manufacturing "smart cement." ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

Batty blood-sucking skeeters follow their nose. Find out how at NSF ’ s The Discovery Files.
Having reviewed a comparative study on mosquitoes, NSF-funded researchers are exploring why blood-sucking flies discriminate when it comes to selecting their hosts. They've learned it's likely an attraction that might not even go skin-deep, but a community of bacteria that has taken up residence on ...This is an NSF Multimedia Gallery item.
