Prevalence of high‐risk plasma p‐tau217 levels and 5‐year transition of risk status in 70‐year‐olds

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION High‐risk plasma p‐tau217 levels predict amyloid‐β pathology in Alzheimer's disease, but little is known about the prevalence and temporal dynamics in the general population. METHODS Participants from the Gothenburg H70 Birth Cohort Study in Sweden were examined (n = 1157) and re‐examined after 5–7 years (n = 771).

Combining Artificial Intelligence and Local Ecological Knowledge to Document the Largest Ever‐Counted Cape Buffalo Mega‐Herd

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Large aggregations of wild mammals are declining worldwide, yet opportunistic wildlife videos from non‐scientists can capture rare or ecologically significant events valuable to conservation. Using drone footage of a Cape buffalo megaherd in northern Botswana, we applied automated detection to estimate a total of about 4100 individuals, the largest ...

The Meaning of Mangabey Molars (And Premolars)

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 2, June 2026.
ABSTRACT The postcanine teeth of mangabeys (members of Cercocebus and Lophocebus) have figured prominently in discussions about the relationship between hard‐object feeding and dental form. Grey‐cheeked mangabeys (Lophocebus albigena) and sooty mangabeys (Cercocebus atys) both have thickly enameled posterior teeth.

La criticalité auto-organisée des feux de forêts marocaines

Revue Marocaine des Sciences Agronomiques et Vétérinaires, 2013
La Criticalité Auto-Organisée (CAO) des feux de forêts marocaines est étudiée à partir d’une analyse d’une série de données historiques (1960 à 2011). En effet, cette analyse montre que les relations entre les surfaces brûlées annuelles normalisées par ...

When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

People and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

Simulated Impacts of the 2023 Megadrought on Black Spruce Potential Productivity Across Canada

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Black spruce (Picea mariana) is a dominant tree species across the Canadian boreal forest and a key contributor to national carbon dynamics. However, its growth and stand productivity are increasingly threatened by intensifying droughts, rising temperatures, and associated disturbances such as wildfire. In this study, we used the process‐based

Opposing Association of Lung Neutrophils and PD‐L1+ Monocytes in Age‐Related Severity of SARS‐CoV‐2 Infection

Aging Cell, Volume 25, Issue 6, June 2026.
Aging skews pulmonary myeloid responses during acute SARS‐CoV‐2 infection toward severe disease. Disease progression is characterized by excessive lung neutrophil accumulation together with impaired activation of classical monocytes, including a defect in PD‐L1 upregulation.
