The structure of semicrystalline polymers largely depends on how strongly their molecular chains are entangled. This has been shown in a new study by researchers from Martin Luther University Halle-Wittenberg (MLU), which ...

Harvard University led research may have solved the puzzle of how life became molecularly right-handed. In the paper, "Origin of biological homochirality by crystallization of an RNA precursor on a magnetic surface," published ...
Producing energy on Earth through nuclear fusion, the type of reaction that powers the sun, has proven to be a major challenge. The extreme conditions needed for such a reaction require the walls of a nuclear fusion device ...
