Do personal traits predict success in school? If so, which dimension of one's outward appearance can tell the most about academic achievement? The answers to these questions are found in a new study by researchers from the ...

AI may offer a better way to ID drug-resistant superbugs

Biomedical engineers at Duke University have shown that different strains of the same bacterial pathogen can be distinguished by a machine learning analysis of their growth dynamics alone, which can then also accurately predict ...
