This international curricular review provides a structured overview of the particle physics content in 27 state, national, and international high-school physics curricula. The review was based on a coding manual that included 60 concepts that were identified as relevant for high-school particle physics education.
Two types of curricula were reviewed, namely curricula with a dedicated particle physics chapter and curricula without a dedicated particle physics chapter.
The results of the curricular review show that particle physics concepts are explicitly or implicitly present in all reviewed curricula.
However, the number of particle physics concepts that are featured in a curriculum varies greatly across the reviewed curricula. We identified core particle physics concepts that can be found in most curricula. Here, elementary particles, fundamental interactions, and charges were identified as explicit particle physics concepts that are featured in more than half of the reviewed curricula either as content or context. Indeed, theoretical particle physics concepts are more prominent in high-school physics curricula than experimental particle physics concepts.
Overall, this international curricular review provides the basis for future curricular development with respect to particle physics and suggests an increased inclusion of experimental particle physics concepts in high-school physics curricula.

The most profound shift in the African hydroclimate of the last 1 million years occurred around 300 thousand years (ka) ago.
This change in African hydroclimate is manifest as an east-west change in moisture balance that cannot be fully explained through linkages to high latitude climate systems.
The east-west shift is, instead, probably driven by a shift in the tropical Walker Circulation related to sea surface temperature change driven by orbital forcing. Comparing records of past vegetation change, and hominin evolution and development, with this breakpoint in the climate system is challenging owing to the paucity of study sites available and uncertainties regarding the dating of records. Notwithstanding these uncertainties we find that, broadly speaking, both vegetation and hominins change around 300 ka.
The vegetative backdrop suggests that relative abundance of vegetative resources shifted from western to eastern Africa, although resources would have persisted across the continent.
The climatic and vegetation changes probably provided challenges for hominins and are broadly coincident with the appearance of Homo sapiens (ca 315 ka) and the emergence of Middle Stone Age technology.
The concomitant changes in climate, vegetation and hominin evolution suggest that these factors are closely intertwined.

Western-style obesity-promoting diets are associated with increased inflammation, higher disease incidence and mortality.
In contrast, plant-based diets (PBDs), which incorporate large amounts of vegetables and fruit, legumes, whole grains and only a small amount of meat, are generally associated with better health and lower mortality.
This narrative review summarizes the evidence on health and life span in adults adhering to PBDs and discusses the potentially longevity-promoting mechanism of PBDs as well as limitations due to nutrient deficiencies.
Epidemiologic studies consistently report lower mortality rates in adults who adhering to PBDs when compared with people whose diet regularly includes meat.
PBDs are associated with many health benefits, such as improved metabolic and inflammatory profile.
In turn, the incidence of cardiovascular disease is lower in adults consuming PBDs, which contributes to their better health. The health-promoting effects of PBDs are still not entirely clear but most likely multifactorial and include modulation of the gut microbiome. The interest in possible longevity-promoting mechanisms of PBDs has increased in recent years, as many characteristics of PBDs such as protein restriction and restriction of certain amino acids are known to extend the life span.
While there is ample evidence from animal studies, large-scale human studies, which also provide insight into the specific mechanisms of the effect of PBDs on longevity, are missing.
However, due to the lower protein content of PBDs, there appears to be an age limit for the anticipated health effects, as adults over 65 require larger amounts of protein.
