A multi-stream network for retrosynthesis prediction
Retrosynthesis aims to predict a set of reactants for producing given molecules, which plays a significant part in the biochemistry field, such as molecular pathway design and drug discovery. Most existing methods only benefit from one kind of inform.....»»
Strictly no dancing: Researchers discover "new molecular design rules"
Since the discovery of quantum mechanics more than a hundred years ago, it has been known that electrons in molecules can be coupled to the motion of the atoms that make up the molecules. Often referred to as molecular vibrations, the motion of atoms.....»»
Catalyst search shows how computing can take the guesswork out of chemistry
Imagine synthesizing and then testing over 50 different complex molecules to identify the most effective catalyst for a particular chemical reaction. The traditional approach to developing new catalysts for chemical reactions in this "try it and see".....»»
Microbiome studies help explore treatments for genetic disorders
A collaboration has led to the identification, in a bacterium of the intestine, of new CRISPR-Cas9 molecules that could have a clinical potential to treat genetic diseases such as retinitis pigmentosa, through sub-retinal injections. Anna Cereseto an.....»»
Variety in building block softness makes for softer amorphous materials
Scientists from Tokyo Metropolitan University have created a new model for disordered materials to study how amorphous materials resist stress. They treated groups of atoms and molecules as squishy spheres with varying softness......»»
