From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Foraging behaviour of equatorial Afrotropical stingless bees: habitat selection and competition for resources [PDF]
, 2008 This thesis is a result of fieldwork on foraging ecology of Afrotropical stingless bees in Uganda. This is because most studies on stingless bee ecology are largely based in South America and South-east Asia and have ignored the aspects of Afrotropical ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

FEBS Letters, EarlyView.CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Local management and landscape effects on diversity of bees, wasps and birds in urban green areas [PDF]
, 2008 Today almost all ecosystems on Earth are directly or indirectly influenced by human activity. Most species occur in ecosystems that are managed by humans and only a small fraction of biodiversity exists in protected areas.

Visual search and decision making in bees: time, speed and accuracy [PDF]
, 2006 An insect searching a meadow for flowers may detect several flowers from different species per second, so the task of choosing the right flowers rapidly is not trivial.
