The evolution of reproduction in Ediacaran–Cambrian metazoans

open access: yesBiological Reviews, EarlyView.
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Pathogenic Variants in Mennonites From Southern Brazil: Implications for Preventive Measures in Public Health

open access: yesClinical Genetics, EarlyView.
In 325 exomes of South Brazilian Mennonites, we identified 23 pathogenic variants (P) and 27 likely P, with founder effects identified for 96% of P, whose frequencies differed from non‐Finnish Europeans, Amish, and Brazilian populations.

open access: yesJournal of the American Ceramic Society, EarlyView.
Abstract A society's wealth relies on three pillars: human capital, nature, and the economy. Sustainable materials development must uphold all three. For load‐bearing materials, mechanical properties, namely, stiffness, strength, and toughness are crucial for human needs, while energy, water usage, and CO2 emissions reflect their ecological footprint ...
