In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could explain both some of the signals from binary black hole mergers observed in gravitational-wave detectors and an important component of the dark matter in the Universe. Significant progress has been achieved both on the theory side and from the point of view of observations, including new models and more accurate calculations of PBH formation, evolution, clustering, merger rates, as well as new astrophysical and cosmological probes.

Diabetes rates are high in Black and some other ethnic communities, often leading to more severe complications. We conducted a study to identify the prevalence and risk of diabetes among African Caribbean Black (ACB) individuals aged 18-39 and to assess the sensitivity of glycated hemoglobin (HbA1c) compared to an oral glucose tolerance test (OGTT) to diagnose diabetes. In this mixed-methods study, maximum variation sampling was used to recruit 272 ACB participants from fourteen African and five Caribbean countries from Toronto.

When relativistic physics is lectured on, interest is focused on the behavior of mechanical and electromagnetic quantities during a reference frame change. However, not only mechanical and electromagnetic quantities transform during a reference frame change; thermodynamic and chemical quantities do too. We will study the transformations of temperature and chemical potential, show how to obtain the corresponding transformation equations with little effort, and exploit the fact that the energy conjugate extensive quantities, namely entropy and amount of substance, are Lorentz-invariant.

Time dilation is an important issue in the field of physics. Introduced by the special relativity theory, it means that the time duration spent by an entity to reach a certain destination depends on the movement and speed of the entity. Time dilation has been widely addressed in other disciplines, including philosophy, psychology, and motivation.

Our present and evolved understanding has challenged the previously synonymous use of the terms 'sex' and 'gender'. We have moved beyond the binary categorization towards proliferation of gender identities. Thus, raising questions whether certain identities are traits or gender identities.
