Universal properties of distorted Kerr-Newman black holes

open access: yes, 2011
We discuss universal properties of axisymmetric and stationary configurations consisting of a central black hole and surrounding matter in Einstein-Maxwell theory. In particular, we find that certain physical equations and inequalities (involving angular

Age of innovation: Progress in systematic botany in the 20th century

open access: yesTAXON, Volume 75, Issue 1, Febuary 2026.
Abstract Systematic botany can be regarded as the oldest of the botanical sciences, having originated with the ancient Greeks. Although much progress has been achieved in systematic botany over nearly two millennia, in the 20th century, many significant innovations took place in revealing processes of evolution, principles and methods of classification,

Dietary Protein Restriction Ameliorates Cardiac Inflammaging via AMPK‐ULK1‐Mediated Mitochondrial Quality Control

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Dietary protein restriction protects the aging heart in the context of obesity by limiting mitochondrial DNA leakage and suppressing cGAS–STING‐driven inflammation. Through AMPK–ULK1‐dependent mitophagy, protein restriction restores mitochondrial quality control, reduces cardiac remodeling, and preserves metabolic homeostasis during obesity‐associated ...

A complex network perspective on brain disease

open access: yesBiological Reviews, Volume 101, Issue 1, Page 364-399, February 2026.
ABSTRACT If brain anatomy and dynamics have a complex network structure as it has become standard to posit, it is reasonable to assume that such a structure should play a key role not only in brain function but also in brain dysfunction. However, exactly how network structure is implicated in brain damage and whether at least some pathologies can be ...

Knowing the Right Thing, but Not Doing It - Knut Hamsun’s Markens grøde in the Anthropocene

open access: yesNORDEUROPAforum - Zeitschrift für Kulturstudien, 2018
Knut Hamsun’s novel Markens grøde has been interpreted as advocating a simple and sustainable life in harmony with nature. However, when read retrospectively against the background of human-made environmental changes that have brought the planet into a ...

A 50‐year perspective on the use and potential of artiodactyl calcanei in bone adaptation studies

open access: yesBiological Reviews, Volume 101, Issue 1, Page 437-485, February 2026.
ABSTRACT Sheep and deer calcanei are important models for studying cortical (compact) and trabecular (cancellous) bone adaptation because they are amenable to direct strain measurement (due to lack of surrounding muscles), experience relatively simple/unidirectional bending, exhibit osteon remodelling, and have the most pronounced regional variations ...

Global diversification of coastal Cafius rove beetles (Coleoptera: Staphylinidae) driven by ocean currents since the early Miocene

open access: yesCladistics, Volume 42, Issue 1, Page 79-94, February 2026.
Abstract As our understanding of abiotic factors continues to grow, along with insights into the biological traits of organisms, so too does the sophistication of studies exploring global diversification and spatio‐temporal distribution patterns. The global distribution of coastal Cafius rove beetles, combined with the endemic distribution patterns ...
