The study builds upon Navin's previous work on the Human Breast Cell Atlas, which profiled over 714,000 cells to generate a comprehensive genetic map of normal breast tissue at the cellular level.

While previous methods were too imprecise to distinguish neighboring cells like mesophyll and bundle sheath cells, single-cell genomics allowed the team to investigate the genetic and structural changes in each cell type from both plants.

This year's nominees may be more recognisable than previous acts were at this stage in their careers.

About one third of the participants in the studies were females, an increase of nearly three-fold from previous studies.

But Juliana Lumumba said previous concerns about the security of the site had prompted the family to move the tooth to a more secure location.
