Synthetic biology—putting engineering into biology [PDF]

open access: yes, 2006
Synthetic biology is interpreted as the engineering-driven building of increasingly complex biological entities for novel applications. Encouraged by progress in the design of artificial gene networks, de novo DNA synthesis and protein engineering, we ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

'Causa efficiens' versus 'Causa finalis': functional explanations in biology [PDF]

open access: yes, 2011
Biology differs from most sciences in its particular way of dealing with the term ‘function’. On the one hand, questions like ‘What is the function of a trait x?’ seem to be perfectly legitimate, realizing that (most) biologists acknowledge that ...

Noise in multiple sclerosis: unwanted and necessary [PDF]

open access: yes, 2014
As our knowledge about the etiology of multiple sclerosis (MS) increases, deterministic paradigms appear insufficient to describe the pathogenesis of the disease, and the impression is that stochastic phenomena (i.e.

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Specificity, propagation, and memory of pericentric heterochromatin

open access: yesMolecular Systems Biology, 2014
The cell establishes heritable patterns of active and silenced chromatin via interacting factors that set, remove, and read epigenetic marks. To understand how the underlying networks operate, we have dissected transcriptional silencing in pericentric ...

Reduced efficacy of a Src kinase inhibitor in crowded protein solution

open access: yesNature Communications, 2021
The intracellular compartment is a crowded environment. Here, the authors use molecular dynamics (MD) simulations to assess inhibitor binding to c-Src kinase and show how ligand binding pathways differ in crowded and dilute protein solutions ...

Building Block and Building Rule: Dual Descriptor Method for Biological Sequence Analysis [PDF]

open access: yes, 2008
The emergence of “Systems Biology” in recent years highlights the systematic viewpoint of bio-system modeling. Building on such a background, Dual Descriptor Method, a generic methodology for biological sequence analysis is proposed. From a

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Genome-wide and high-density CRISPR-Cas9 screens identify point mutations in PARP1 causing PARP inhibitor resistance

open access: yesNature Communications, 2018
The mechanisms of PARP inhibitor (PARPi) resistance are poorly understood. Here the authors employ a CRISPR mutagenesis approach to identify PARP1 mutants causing PARPi resistance and find that PARP1 mutations are tolerated in BRCA1 mutated cells ...
