text: The hippocampus has a major role in encoding and consolidating long-term memories,
and undergoes plastic changes during sleep1. These changes require precise homeostatic
control by subcortical neuromodulatory structures2. The underlying mechanisms
of this phenomenon, however, remain unknown. Here, using multi-structure recordings
in macaque monkeys, we show that the brainstem transiently modulates hippocampal
network events through phasic pontine waves known as pontogeniculooccipital waves
(PGO waves). Two physiologically distinct types of PGO wave appear to occur sequentially,
selectively influencing high-frequency ripples and low-frequency theta events,
respectively. The two types of PGO wave are associated with opposite hippocampal
spike-field coupling, prompting periods of high neural synchrony of neural populations
during periods of ripple and theta instances. The coupling between PGO waves and
ripples, classically associated with distinct sleep stages, supports the notion
that a global coordination mechanism of hippocampal sleep dynamics by cholinergic
pontine transients may promote systems and synaptic memory consolidation as well
as synaptic homeostasis.

text: Growth regulation tailors development in plants to their environment. A prominent
example of this is the response to gravity, in which shoots bend up and roots
bend down1. This paradox is based on opposite effects of the phytohormone auxin,
which promotes cell expansion in shoots while inhibiting it in roots via a yet
unknown cellular mechanism2. Here, by combining microfluidics, live imaging, genetic
engineering and phosphoproteomics in Arabidopsis thaliana, we advance understanding
of how auxin inhibits root growth. We show that auxin activates two distinct,
antagonistically acting signalling pathways that converge on rapid regulation
of apoplastic pH, a causative determinant of growth. Cell surface-based TRANSMEMBRANE
KINASE1 (TMK1) interacts with and mediates phosphorylation and activation of plasma
membrane H+-ATPases for apoplast acidification, while intracellular canonical
auxin signalling promotes net cellular H+ influx, causing apoplast alkalinization.
Simultaneous activation of these two counteracting mechanisms poises roots for
rapid, fine-tuned growth modulation in navigating complex soil environments.

text: Eukaryotic cells migrate by coupling the intracellular force of the actin
cytoskeleton to the environment. While force coupling is usually mediated by transmembrane
adhesion receptors, especially those of the integrin family, amoeboid cells such
as leukocytes can migrate extremely fast despite very low adhesive forces1. Here
we show that leukocytes cannot only migrate under low adhesion but can also transmit
forces in the complete absence of transmembrane force coupling. When confined
within three-dimensional environments, they use the topographical features of
the substrate to propel themselves. Here the retrograde flow of the actin cytoskeleton
follows the texture of the substrate, creating retrograde shear forces that are
sufficient to drive the cell body forwards. Notably, adhesion-dependent and adhesion-independent
migration are not mutually exclusive, but rather are variants of the same principle
of coupling retrograde actin flow to the environment and thus can potentially
operate interchangeably and simultaneously. As adhesion-free migration is independent
of the chemical composition of the environment, it renders cells completely autonomous
in their locomotive behaviour.

text: 'High-speed optical telecommunication is enabled by wavelength-division multiplexing,
whereby hundreds of individually stabilized lasers encode information within a
single-mode optical fibre. Higher bandwidths require higher total optical power,
but the power sent into the fibre is limited by optical nonlinearities within
the fibre, and energy consumption by the light sources starts to become a substantial
cost factor1. Optical frequency combs have been suggested to remedy this problem
by generating numerous discrete, equidistant laser lines within a monolithic device;
however, at present their stability and coherence allow them to operate only within
small parameter ranges2,3,4. Here we show that a broadband frequency comb realized
through the electro-optic effect within a high-quality whispering-gallery-mode
resonator can operate at low microwave and optical powers. Unlike the usual third-order
Kerr nonlinear optical frequency combs, our combs rely on the second-order nonlinear
effect, which is much more efficient. Our result uses a fixed microwave signal
that is mixed with an optical-pump signal to generate a coherent frequency comb
with a precisely determined carrier separation. The resonant enhancement enables
us to work with microwave powers that are three orders of magnitude lower than
those in commercially available devices. We emphasize the practical relevance
of our results to high rates of data communication. To circumvent the limitations
imposed by nonlinear effects in optical communication fibres, one has to solve
two problems: to provide a compact and fully integrated, yet high-quality and
coherent, frequency comb generator; and to calculate nonlinear signal propagation
in real time5. We report a solution to the first problem.'

text: Adult intestinal stem cells are located at the bottom of crypts of Lieberkühn,
where they express markers such as LGR5 1,2 and fuel the constant replenishment
of the intestinal epithelium1. Although fetal LGR5-expressing cells can give rise
to adult intestinal stem cells3,4, it remains unclear whether this population
in the patterned epithelium represents unique intestinal stem-cell precursors.
Here we show, using unbiased quantitative lineage-tracing approaches, biophysical
modelling and intestinal transplantation, that all cells of the mouse intestinal
epithelium—irrespective of their location and pattern of LGR5 expression in the
fetal gut tube—contribute actively to the adult intestinal stem cell pool. Using
3D imaging, we find that during fetal development the villus undergoes gross remodelling
and fission. This brings epithelial cells from the non-proliferative villus into
the proliferative intervillus region, which enables them to contribute to the
adult stem-cell niche. Our results demonstrate that large-scale remodelling of
the intestinal wall and cell-fate specification are closely linked. Moreover,
these findings provide a direct link between the observed plasticity and cellular
reprogramming of differentiating cells in adult tissues following damage5,6,7,8,9,
revealing that stem-cell identity is an induced rather than a hardwired property.

text: Direct reciprocity is a powerful mechanism for the evolution of cooperation
on the basis of repeated interactions1,2,3,4. It requires that interacting individuals
are sufficiently equal, such that everyone faces similar consequences when they
cooperate or defect. Yet inequality is ubiquitous among humans5,6 and is generally
considered to undermine cooperation and welfare7,8,9,10. Most previous models
of reciprocity do not include inequality11,12,13,14,15. These models assume that
individuals are the same in all relevant aspects. Here we introduce a general
framework to study direct reciprocity among unequal individuals. Our model allows
for multiple sources of inequality. Subjects can differ in their endowments, their
productivities and in how much they benefit from public goods. We find that extreme
inequality prevents cooperation. But if subjects differ in productivity, some
endowment inequality can be necessary for cooperation to prevail. Our mathematical
predictions are supported by a behavioural experiment in which we vary the endowments
and productivities of the subjects. We observe that overall welfare is maximized
when the two sources of heterogeneity are aligned, such that more productive individuals
receive higher endowments. By contrast, when endowments and productivities are
misaligned, cooperation quickly breaks down. Our findings have implications for
policy-makers concerned with equity, efficiency and the provisioning of public
goods.
