Johns Hopkins engineers have developed gel strips that change shape when given chemical instructions written in DNA code. These "gel automata," measuring just centimeters, can grow or shrink, ...

It seeks to explain biological function in terms of molecular structure, dynamics and organization, from single molecules to supramolecular structures. The authors show that DCAF1, a substrate ...

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules such as nucleic acids and proteins that carry out the biological ...

This breakthrough allows for the visualization of photons and could revolutionize nanophotonic technologies, enhancing secure communication, pathogen detection, and molecular control in chemical ...

Concatenates two open paths (returns NULL if either path is closed). path '[(0,0),(1,1)]' + path '[(2,2),(3,3),(4,4)]' → [(0,0),(1,1),(2,2),(3,3),(4,4)] ...
