New research from the University of Waterloo suggests that more than creativity is at play. Behind many great melodies, researchers found something surprisingly powerful: symmetry. Their work shows that advanced algebra can reveal deep musical patterns that are not always obvious by ear or even on a written score. 

The findings could help composers better understand what makes melodies work, as the study offers a recipe for generating new melodies that follow specific symmetry rules, opening new creative possibilities for composers and researchers. 

As universities increasingly adopt digital tools and automated analytics systems, attention often centers on these tools’ gains in accuracy and efficiency. Far less visible, however, is another critical dimension: the additional work students must do to produce, organize, and interpret their own data within these systems.

Despite their widespread use in various applications, synthetic polymers such as polyethylene (PE) remain susceptible to structural deformation when exposed to stress. In a new study, scientists from Japan have utilized focused electron beam (FEB) irradiation to precisely induce micro-voids and nano-scale fibrils to improve the mechanical strength of PE. Following irradiation with FEB, PE demonstrated minimal crack opening and prevented further crack propagation. This study can fuel the development of superior polymer-based materials.

A new study from Murdoch University reveals that components of restored Banksia woodlands may struggle to cope with fire as effectively as natural bushland.
