Is Evolution by Natural Selection the Algorithm of Biological Evolution? [PDF]
Artificial Life 13, 2012 It is tempting to be confident that we know how biological evolution works. After all, we know a mechanism capable of producing adaptation, and we understand the necessary and sufficient conditions for this to occur, and those conditions are met in natural populations – the rest is surely just details.

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

FEBS Letters, EarlyView.Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Soil bacterial community and functional shifts in response to altered snowpack in moist acidic tundra of northern Alaska [PDF]
SOIL, 2016 Soil microbial communities play a central role in the cycling of carbon (C) in Arctic tundra ecosystems, which contain a large portion of the global C pool.

Decoding the dual role of autophagy in cancer through transcriptional and epigenetic regulation
FEBS Letters, EarlyView.Transcriptional and epigenetic regulation controls autophagy, which exerts context‐dependent effects on cancer: Autophagy suppresses tumorigenesis by maintaining cellular homeostasis or promotes tumor progression by supporting survival under stress. In this “In a Nutshell” article, we explore the intricate mechanisms of the dual function of autophagy ...

Axiological and epistemological contributions to teaching the theory of evolution Darwin [PDF]
Investigações em Ensino de Ciências, 2011 From the essential role of theme “biological evolution” in scientific formation of students and the diversity of issues identified in the literature for teaching of the same, we developed a qualitative study through contributions of Didactics of Science ...

Cultural and Biological Evolution [PDF]
, 2021 AbstractAlthough there is no necessary relation between “big data” and “monism”—the program of reducing cultural and mental processes to computational and biological principles—both these programs reject a dualism between res extensa and res cogitans. Opposing this philosophy of science, I have argued in the above chapter that a second contingency of ...

Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.
