Evolutionary activation of acidic chitinase in herbivores through the H128R mutation in ruminant livestock

iScience, 2023
Summary: Placental mammals' ancestors were insectivores, suggesting that modern mammals may have inherited the ability to digest insects. Acidic chitinase (Chia) is a crucial enzyme hydrolyzing significant component of insects' exoskeleton in many ...

Oncogenic stress alters predator-prey interactions between a globally invasive and a native planaria species

iScience
Summary: Oncogenic pressures, factors that increase tumor risk, are intensifying with human-driven environmental change, yet their ecological effects remain mainly unquantified.

Developmental biology, the stem cell of biological disciplines. [PDF]

PLoS Biology, 2017
Developmental biology (including embryology) is proposed as "the stem cell of biological disciplines." Genetics, cell biology, oncology, immunology, evolutionary mechanisms, neurobiology, and systems biology each has its ancestry in developmental biology.

Long-term culturing of Pseudomonas aeruginosa in static, minimal nutrient medium results in increased pyocyanin production, reduced biofilm production, and loss of motility

Applied and Environmental Microbiology
Pseudomonas aeruginosa is a multidrug-resistant opportunistic human pathogen that can survive in many natural and anthropogenic environments. It is a leading cause of morbidity in individuals with cystic fibrosis and is one of the most prevalent ...

Environmental influence on Pristionchus pacificus mouth form through different culture methods

Scientific Reports, 2017
Environmental cues can impact development to elicit distinct phenotypes in the adult. The consequences of phenotypic plasticity can have profound effects on morphology, life cycle, and behavior to increase the fitness of the organism.

Genome structure and evolutionary history of frankincense producing Boswellia sacra

iScience, 2022
Summary: Boswellia sacra Flueck (family Burseraceae) tree is wounded to produce frankincense. We report its de novo assembled genome (667.8 Mb) comprising 18,564 high-confidence protein-encoding genes.

Acceptance of Evolution Increases with Student Academic Level: A Comparison Between a Secular and a Religious College [PDF]

, 2009
Acceptance of evolution among the general public, high schools, teachers, and scientists has been documented in the USA; little is known about college students’ views on evolution; this population is relevant since it transits from a high-school/parent ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Early genome erosion and internal phage-symbiont-host interaction in the endosymbionts of a cold-seep tubeworm

iScience, 2023
Summary: Endosymbiosis with chemosynthetic Gammaproteobacteria is widely recognized as an adaptive mechanism of siboglinid tubeworms, yet evolution of these endosymbionts and their driving forces remain elusive.

Evolutionary Biology and Rape [PDF]

, 1999
This article queries whether an evolutionary analysis of rape may be more compelling in explaining a rape victim\u27s fear than a defendant\u27s sexual aggression. Such a victim-oriented approach could help legal decisionmakers assess the reasonableness
