3-D printed ‘building blocks’ of life
Could be used to build tissue structures and eventually micro-organs
November 4, 2015
Chinese and U.S. scientists have developed a 3-D printing method capable of producing embryoid bodies — highly uniform “blocks” of embryonic stem cells. These cells, which are capable of generating all cell types in the body, could be used to build tissue structures and potentially even micro-organs.
Photons could travel side by side a specific distance from each other — similar to how two hydrogen atoms sit next to each other in a hydrogen molecule — theoretical physicists from the National Institute of Standards and Technology (NIST) and the University of Maryland (with other collaborators) have shown.
“It’s not a molecule per se, but you can imagine it as having a similar kind of structure,” says NIST’s Alexey Gorshkov. “We’re learning how to build complex states of light that, in turn, can be built into more complex objects. This is the first time anyone has shown how to bind two photons a finite distance apart.
