Brush-Tailed bettongs make a comeback in Southern Australia
After more than a century of disappearance, cute marsupials that resemble “mini kangaroos on steroids” are making a comeback in southern Australia. The active brush-tailed bettong (Bettongia penicillata), also known as yalgiri by the local Narungga People, used to hop and dart across a large portion of the Australian mainland. Their population has decreased over…

Panoptic quality should be avoided as a metric for assessing cell nuclei segmentation and classification in digital pathology
Material and methods To show the concrete impact of our theoretical analysis, we select two public digital pathology datasets designed for instance segmentation and classification: NuCLS15, and the MoNuSAC challenge dataset3. NuCLS dataset and experiments The NuCLS dataset15 proposes a “crowdsourced” dataset where the annotations are made by non-pathologists from algorithmic suggestions, and with corrections…

How to Create A Breathtaking Space with Biophilic Design
In today’s fast-paced world, the longing for a deeper connection with nature has become increasingly vital. Biophilic design, a concept rooted in our innate affinity for life and the natural world, offers a transformative approach to architecture. Coined by biologist Edward O. Wilson, biophilia has found expression in our built environments since ancient times, with…
