Entropic effects in cell lineage tree packings
(Springer Science+Business Media, 2018-08-08)
Optimal packings [1, 2] of unconnected objects have been studied for centuries [3–6], but the packing principles of linked objects, such as topologically complex polymers [7, 8] or cell lineages [9, 10], are yet to be fully ...
Designing yeast as plant-like hyperaccumulators for heavy metals
(Springer Science and Business Media LLC, 2019-11-08)
Hyperaccumulators typically refer to plants that absorb and tolerate elevated amounts of heavy metals. Due to their unique metal trafficking abilities, hyperaccumulators are promising candidates for bioremediation applications. ...
ASCL1 is a MYCN- and LMO1-dependent member of the adrenergic neuroblastoma core regulatory circuitry
(Springer Science and Business Media LLC, 2019-12)
A heritable polymorphism within regulatory sequences of the LMO1 gene is associated with its elevated expression and increased susceptibility to develop neuroblastoma, but the oncogenic pathways downstream of the LMO1 ...
Repeated evolution of cytochrome P450-mediated spiroketal steroid biosynthesis in plants
(Springer Science and Business Media LLC, 2019-07-19)
Diosgenin is a spiroketal steroidal natural product extracted from plants and used as the single most important precursor for the world steroid hormone industry. The sporadic occurrences of diosgenin in distantly related ...
Complex DNA knots detected with a nanopore sensor
(Springer Science and Business Media LLC, 2019-10-02)
Equilibrium knots are common in biological polymers—their prevalence, size distribution, structure, and dynamics have been extensively studied, with implications to fundamental biological processes and DNA sequencing ...
Mortality causes universal changes in microbial community composition
(Springer Science and Business Media LLC, 2019-05-09)
All organisms are sensitive to the abiotic environment, and a deteriorating environment can cause extinction. However, survival in a multispecies community depends upon interactions, and some species may even be favored ...
Discovery of TaFeSb-based half-Heuslers with high thermoelectric performance
(Springer Science and Business Media LLC, 2019-01-17)
Discovery of thermoelectric materials has long been realized by the Edisonian trial and error approach. However, recent progress in theoretical calculations, including the ability to predict structures of unknown phases ...
Creating fluorescent quantum defects in carbon nanotubes using hypochlorite and light
(Springer Science and Business Media LLC, 2019-06-28)
Covalent doping of single-walled carbon nanotubes (SWCNTs) can modify their optical properties, enabling applications as single-photon emitters and bio-imaging agents. We report here a simple, quick, and controllable method ...
Percolative Scale-Free Behavior in the Boiling Crisis
(American Physical Society (APS), 2019-04-05)
We present the first experimental observations of scale-free behavior in the bubble footprint distribution during the boiling crisis of water, in pool and flow boiling conditions. We formulate a continuum percolation model ...
Molecular model of J-aggregated pseudoisocyanine fibers
(AIP Publishing, 2018-07-14)
Aggregated cyanines form ordered supramolecular structures with the potential to transport energy efficiently over long distances, a hallmark of photosynthetic light-harvesting complexes. In concentrated aqueous solution, ...
