text: Spatial regulation of the plant hormone indole-3-acetic acid (IAA, or auxin)
is essential for plant development. Auxin gradient establishment is mediated by
polarly localized auxin transporters, including PIN-FORMED (PIN) proteins. Their
localization and abundance at the plasma membrane are tightly regulated by endomembrane
machinery, especially the endocytic and recycling pathways mediated by the ADP
ribosylation factor guanine nucleotide exchange factor (ARF-GEF) GNOM. We assessed
the role of the early secretory pathway in establishing PIN1 polarity in Arabidopsis
thaliana by pharmacological and genetic approaches. We identified the compound
endosidin 8 (ES8), which selectively interferes with PIN1 basal polarity without
altering the polarity of apical proteins. ES8 alters the auxin distribution pattern
in the root and induces a strong developmental phenotype, including reduced root
length. The ARF-GEF- defective mutants gnom-like 1 ( gnl1-1) and gnom ( van7)
are significantly resistant to ES8. The compound does not affect recycling or
vacuolar trafficking of PIN1 but leads to its intracellular accumulation, resulting
in loss of PIN1 basal polarity at the plasma membrane. Our data confirm a role
for GNOM in endoplasmic reticulum (ER) - Golgi trafficking and reveal that a GNL1/GNOM-mediated
early secretory pathway selectively regulates PIN1 basal polarity establishment
in a manner essential for normal plant development.

text: Grounding autonomous behavior in the nervous system is a fundamental challenge
for neuroscience. In particular, self-organized behavioral development provides
more questions than answers. Are there special functional units for curiosity,
motivation, and creativity? This paper argues that these features can be grounded
in synaptic plasticity itself, without requiring any higher-level constructs.
We propose differential extrinsic plasticity (DEP) as a new synaptic rule for
self-learning systems and apply it to a number of complex robotic systems as a
test case. Without specifying any purpose or goal, seemingly purposeful and adaptive
rhythmic behavior is developed, displaying a certain level of sensorimotor intelligence.
These surprising results require no systemspecific modifications of the DEP rule.
They rather arise from the underlying mechanism of spontaneous symmetry breaking,which
is due to the tight brain body environment coupling. The new synaptic rule is
biologically plausible and would be an interesting target for neurobiological
investigation. We also argue that this neuronal mechanism may have been a catalyst
in natural evolution.

text: Epistatic interactions can frustrate and shape evolutionary change. Indeed,
phenotypes may fail to evolve when essential mutations are only accessible through
positive selection if they are fixed simultaneously. How environmental variability
affects such constraints is poorly understood. Here, we studied genetic constraints
in fixed and fluctuating environments using the Escherichia coli lac operon as
a model system for genotype-environment interactions. We found that, in different
fixed environments, all trajectories that were reconstructed by applying point
mutations within the transcription factor-operator interface became trapped at
suboptima, where no additional improvements were possible. Paradoxically, repeated
switching between these same environments allows unconstrained adaptation by continuous
improvements. This evolutionary mode is explained by pervasive cross-environmental
tradeoffs that reposition the peaks in such a way that trapped genotypes can repeatedly
climb ascending slopes and hence, escape adaptive stasis. Using a Markov approach,
we developed a mathematical framework to quantify the landscape-crossing rates
and show that this ratchet-like adaptive mechanism is robust in a wide spectrum
of fluctuating environments. Overall, this study shows that genetic constraints
can be overcome by environmental change and that crossenvironmental tradeoffs
do not necessarily impede but also, can facilitate adaptive evolution. Because
tradeoffs and environmental variability are ubiquitous in nature, we speculate
this evolutionary mode to be of general relevance.

text: "We consider the quantum ferromagnetic Heisenberg model in three dimensions,
for all spins S ≥ 1/2. We rigorously prove the validity of the spin-wave approximation
for the excitation spectrum, at the level of the first non-trivial contribution
to the free energy at low temperatures. Our proof comes with explicit, constructive
upper and lower bounds on the error term. It uses in an essential way the bosonic
formulation of the model in terms of the Holstein-Primakoff representation. In
this language, the model describes interacting bosons with a hard-core on-site
repulsion and a nearest-neighbor attraction. This attractive interaction makes
the lower bound on the free energy particularly tricky: the key idea there is
to prove a differential inequality for the two-particle density, which is thereby
shown to be smaller than the probability density of a suitably weighted two-particle
random process on the lattice.\r\n"

text: Synapsins (Syns) are an evolutionarily conserved family of presynaptic proteins
crucial for the fine-tuning of synaptic function. A large amount of experimental
evidences has shown that Syns are involved in the development of epileptic phenotypes
and several mutations in Syn genes have been associated with epilepsy in humans
and animal models. Syn mutations induce alterations in circuitry and neurotransmitter
release, differentially affecting excitatory and inhibitory synapses, thus causing
an excitation/inhibition imbalance in network excitability toward hyperexcitability
that may be a determinant with regard to the development of epilepsy. Another
approach to investigate epileptogenic mechanisms is to understand how silencing
Syn affects the cellular behavior of single neurons and is associated with the
hyperexcitable phenotypes observed in epilepsy. Here, we examined the functional
effects of antisense-RNA inhibition of Syn expression on individually identified
and isolated serotonergic cells of the Helix land snail. We found that Helix synapsin
silencing increases cell excitability characterized by a slightly depolarized
resting membrane potential, decreases the rheobase, reduces the threshold for
action potential (AP) firing and increases the mean and instantaneous firing rates,
with respect to control cells. The observed increase of Ca2+ and BK currents in
Syn-silenced cells seems to be related to changes in the shape of the AP waveform.
These currents sustain the faster spiking in Syn-deficient cells by increasing
the after hyperpolarization and limiting the Na+ and Ca2+ channel inactivation
during repetitive firing. This in turn speeds up the depolarization phase by reaching
the AP threshold faster. Our results provide evidence that Syn silencing increases
intrinsic cell excitability associated with increased Ca2+ and Ca2+-dependent
BK currents in the absence of excitatory or inhibitory inputs.

text: Contrary to the pattern seen in mammalian sex chromosomes, where most Y-linked
genes have X-linked homologs, the Drosophila X and Y chromosomes appear to be
unrelated. Most of the Y-linked genes have autosomal paralogs, so autosome-to-Y
transposition must be the main source of Drosophila Y-linked genes. Here we show
how these genes were acquired. We found a previously unidentified gene (flagrante
delicto Y, FDY) that originated from a recent duplication of the autosomal gene
vig2 to the Y chromosome of Drosophila melanogaster. Four contiguous genes were
duplicated along with vig2, but they became pseudogenes through the accumulation
of deletions and transposable element insertions, whereas FDY remained functional,
acquired testis-specific expression, and now accounts for ∼20% of the vig2-like
mRNA in testis. FDY is absent in the closest relatives of D. melanogaster, and
DNA sequence divergence indicates that the duplication to the Y chromosome occurred
∼2 million years ago. Thus, FDY provides a snapshot of the early stages of the
establishment of a Y-linked gene and demonstrates how the Drosophila Y has been
accumulating autosomal genes.

text: We show that the Galois group of any Schubert problem involving lines in projective
space contains the alternating group. This constitutes the largest family of enumerative
problems whose Galois groups have been largely determined. Using a criterion of
Vakil and a special position argument due to Schubert, our result follows from
a particular inequality among Kostka numbers of two-rowed tableaux. In most cases,
a combinatorial injection proves the inequality. For the remaining cases, we use
the Weyl integral formulas to obtain an integral formula for these Kostka numbers.
This rewrites the inequality as an integral, which we estimate to establish the
inequality.

text: We prove that the dual of the digital Voronoi diagram constructed by flooding
the plane from the data points gives a geometrically and topologically correct
dual triangulation. This provides the proof of correctness for recently developed
GPU algorithms that outperform traditional CPU algorithms for constructing two-dimensional
Delaunay triangulations.

text: In animal embryos, morphogen gradients determine tissue patterning and morphogenesis.
Shyer et al. provide evidence that, during vertebrate gut formation, tissue folding
generates graded activity of signals required for subsequent steps of gut growth
and differentiation, thereby revealing an intriguing link between tissue morphogenesis
and morphogen gradient formation.
