text: The quantum anomalous Hall (QAH) effect combines topology and magnetism to
produce precisely quantized Hall resistance at zero magnetic field. We report
the observation of a QAH effect in twisted bilayer graphene aligned to hexagonal
boron nitride. The effect is driven by intrinsic strong interactions, which polarize
the electrons into a single spin- and valley-resolved moiré miniband with Chern
number C = 1. In contrast to magnetically doped systems, the measured transport
energy gap is larger than the Curie temperature for magnetic ordering, and quantization
to within 0.1% of the von Klitzing constant persists to temperatures of several
kelvin at zero magnetic field. Electrical currents as small as 1 nanoampere controllably
switch the magnetic order between states of opposite polarization, forming an
electrically rewritable magnetic memory.

text: The discovery of superconductivity and exotic insulating phases in twisted
bilayer graphene has established this material as a model system of strongly correlated
electrons. To achieve superconductivity, the two layers of graphene need to be
at a very precise angle with respect to each other. Yankowitz et al. now show
that another experimental knob, hydrostatic pressure, can be used to tune the
phase diagram of twisted bilayer graphene (see the Perspective by Feldman). Applying
pressure increased the coupling between the layers, which shifted the superconducting
transition to higher angles and somewhat higher temperatures.

text: The anomalous metallic state in the high-temperature superconducting cuprates
is masked by superconductivity near a quantum critical point. Applying high magnetic
fields to suppress superconductivity has enabled detailed studies of the normal
state, yet the direct effect of strong magnetic fields on the metallic state is
poorly understood. We report the high-field magnetoresistance of thin-film La2–xSrxCuO4
cuprate in the vicinity of the critical doping, 0.161 ≤ p ≤ 0.190. We find that
the metallic state exposed by suppressing superconductivity is characterized by
magnetoresistance that is linear in magnetic fields up to 80 tesla. The magnitude
of the linear-in-field resistivity mirrors the magnitude and doping evolution
of the well-known linear-in-temperature resistivity that has been associated with
quantum criticality in high-temperature superconductors.

text: 'Cuprate superconductors have long been thought of as having strong electronic
correlations but negligible spin-orbit coupling. Using spin- and angle-resolved
photoemission spectroscopy, we discovered that one of the most studied cuprate
superconductors, Bi2212, has a nontrivial spin texture with a spin-momentum locking
that circles the Brillouin zone center and a spin-layer locking that allows states
of opposite spin to be localized in different parts of the unit cell. Our findings
pose challenges for the vast majority of models of cuprates, such as the Hubbard
model and its variants, where spin-orbit interaction has been mostly neglected,
and open the intriguing question of how the high-temperature superconducting state
emerges in the presence of this nontrivial spin texture. '

text: Self-assembly of inorganic nanoparticles has been used to prepare hundreds
of different colloidal crystals, but almost invariably with the restriction that
the particles must be densely packed. Here, we show that non–close-packed nanoparticle
arrays can be fabricated through the selective removal of one of two components
comprising binary nanoparticle superlattices. First, a variety of binary nanoparticle
superlattices were prepared at the liquid-air interface, including several arrangements
that were previously unknown. Molecular dynamics simulations revealed the particular
role of the liquid in templating the formation of superlattices not achievable
through self-assembly in bulk solution. Second, upon stabilization, all of these
binary superlattices could be transformed into distinct “nanoallotropes”—nanoporous
materials having the same chemical composition but differing in their nanoscale
architectures.

text: Although methane is a volatile gas, it can be efficiently trapped in ice,
which can then be readily set on fire. Beyond the curiosity of this “burning ice,”
caged methane is of great importance as one of the world's largest natural gas
resources. In these materials, known as clathrates, methane molecules are tightly
bound in nanometer-sized, regularly interspaced cages. Other inorganic materials,
such as the silica mineral chibaite, can similarly encapsulate methane and higher
hydrocarbons. Simple organic compounds have also been found to trap various organic
molecules upon crystallization.

text: Time-resolved x-ray absorption spectroscopy (TR-XAS) has so far practically
been limited to large-scale facilities, to subpicosecond temporal resolution,
and to the condensed phase. We report the realization of TR-XAS with a temporal
resolution in the low femtosecond range by developing a tabletop high-harmonic
source reaching up to 350 electron volts, thus partially covering the spectral
region of 280 to 530 electron volts, where water is transmissive. We used this
source to follow previously unexamined light-induced chemical reactions in the
lowest electronic states of isolated CF4+ and SF6+ molecules in the gas phase.
By probing element-specific core-to-valence transitions at the carbon K-edge or
the sulfur L-edges, we characterized their reaction paths and observed the effect
of symmetry breaking through the splitting of absorption bands and Rydberg-valence
mixing induced by the geometry changes.

text: We describe an approach to bottom-up fabrication that allows integration of
the functional diversity of proteins into designed three-dimensional structural
frameworks. A set of custom staple proteins based on transcription activator–like
effector proteins folds a double-stranded DNA template into a user-defined shape.
Each staple protein is designed to recognize and closely link two distinct double-helical
DNA sequences at separate positions on the template. We present design rules for
constructing megadalton-scale DNA-protein hybrid shapes; introduce various structural
motifs, such as custom curvature, corners, and vertices; and describe principles
for creating multilayer DNA-protein objects with enhanced rigidity. We demonstrate
self-assembly of our hybrid nanostructures in one-pot mixtures that include the
genetic information for the designed proteins, the template DNA, RNA polymerase,
ribosomes, and cofactors for transcription and translation.

text: The ultrafast motion of electrons and holes after light-matter interaction
is fundamental to a broad range of chemical and biophysical processes. We advanced
high-harmonic spectroscopy to resolve spatially and temporally the migration of
an electron hole immediately after ionization of iodoacetylene while simultaneously
demonstrating extensive control over the process. A multidimensional approach,
based on the measurement and accurate theoretical description of both even and
odd harmonic orders, enabled us to reconstruct both quantum amplitudes and phases
of the electronic states with a resolution of ~100 attoseconds. We separately
reconstructed quasi-field-free and laser-controlled charge migration as a function
of the spatial orientation of the molecule and determined the shape of the hole
created by ionization. Our technique opens the prospect of laser control over
electronic primary processes.

text: Organizing inorganic nanocrystals into complex architectures is challenging
and typically relies on preexisting templates, such as properly folded DNA or
polypeptide chains. We found that under carefully controlled conditions, cubic
nanocrystals of magnetite self-assemble into arrays of helical superstructures
in a template-free manner with >99% yield. Computer simulations revealed that
the formation of helices is determined by the interplay of van der Waals and magnetic
dipole-dipole interactions, Zeeman coupling, and entropic forces and can be attributed
to spontaneous formation of chiral nanocube clusters. Neighboring helices within
their densely packed ensembles tended to adopt the same handedness in order to
maximize packing, thus revealing a novel mechanism of symmetry breaking and chirality
amplification.

text: Spontaneous formation of colonies of bacteria or flocks of birds are examples
of self-organization in active living matter. Here, we demonstrate a form of self-organization
from nonequilibrium driving forces in a suspension of synthetic photoactivated
colloidal particles. They lead to two-dimensional "living crystals," which form,
break, explode, and re-form elsewhere. The dynamic assembly results from a competition
between self-propulsion of particles and an attractive interaction induced respectively
by osmotic and phoretic effects and activated by light. We measured a transition
from normal to giant-number fluctuations. Our experiments are quantitatively described
by simple numerical simulations. We show that the existence of the living crystals
is intrinsically related to the out-of-equilibrium collisions of the self-propelled
particles.

text: To combat the functional decline of the proteome, cells use the process of
protein turnover to replace potentially impaired polypeptides with new functional
copies. We found that extremely long-lived proteins (ELLPs) did not turn over
in postmitotic cells of the rat central nervous system. These ELLPs were associated
with chromatin and the nuclear pore complex, the central transport channels that
mediate all molecular trafficking in and out of the nucleus. The longevity of
these proteins would be expected to expose them to potentially harmful metabolites,
putting them at risk of accumulating damage over extended periods of time. Thus,
it is possible that failure to maintain proper levels and functional integrity
of ELLPs in nonproliferative cells might contribute to age-related deterioration
in cell and tissue function.

text: The Arabidopsis thaliana central cell, the companion cell of the egg, undergoes
DNA demethylation before fertilization, but the targeting preferences, mechanism,
and biological significance of this process remain unclear. Here, we show that
active DNA demethylation mediated by the DEMETER DNA glycosylase accounts for
all of the demethylation in the central cell and preferentially targets small,
AT-rich, and nucleosome-depleted euchromatic transposable elements. The vegetative
cell, the companion cell of sperm, also undergoes DEMETER-dependent demethylation
of similar sequences, and lack of DEMETER in vegetative cells causes reduced small
RNA–directed DNA methylation of transposons in sperm. Our results demonstrate
that demethylation in companion cells reinforces transposon methylation in plant
gametes and likely contributes to stable silencing of transposable elements across
generations.

text: Eukaryotic cytosine methylation represses transcription but also occurs in
the bodies of active genes, and the extent of methylation biology conservation
is unclear. We quantified DNA methylation in 17 eukaryotic genomes and found that
gene body methylation is conserved between plants and animals, whereas selective
methylation of transposons is not. We show that methylation of plant transposons
in the CHG context extends to green algae and that exclusion of histone H2A.Z
from methylated DNA is conserved between plants and animals, and we present evidence
for RNA-directed DNA methylation of fungal genes. Our data demonstrate that extant
DNA methylation systems are mosaics of conserved and derived features, and indicate
that gene body methylation is an ancient property of eukaryotic genomes.

text: Parent-of-origin-specific (imprinted) gene expression is regulated in Arabidopsis
thaliana endosperm by cytosine demethylation of the maternal genome mediated by
the DNA glycosylase DEMETER, but the extent of the methylation changes is not
known. Here, we show that virtually the entire endosperm genome is demethylated,
coupled with extensive local non-CG hypermethylation of small interfering RNA–targeted
sequences. Mutation of DEMETER partially restores endosperm CG methylation to
levels found in other tissues, indicating that CG demethylation is specific to
maternal sequences. Endosperm demethylation is accompanied by CHH hypermethylation
of embryo transposable elements. Our findings demonstrate extensive reconfiguration
of the endosperm methylation landscape that likely reinforces transposon silencing
in the embryo.

text: Deformable, spherical aggregates of metal nanoparticles connected by long-chain
dithiol ligands self-assemble into nanostructured materials of macroscopic dimensions.
These materials are plastic and moldable against arbitrarily shaped masters and
can be thermally hardened into polycrystalline metal structures of controllable
porosity. In addition, in both plastic and hardened states, the assemblies are
electrically conductive and exhibit Ohmic characteristics down to ∼20 volts per
meter. The self-assembly method leading to such materials is applicable both to
pure metals and to bimetallic structures of various elemental compositions.

text: Proteins of the ARGONAUTE family are important in diverse posttranscriptional
RNA-mediated gene-silencing systems as well as in transcriptional gene silencing
in Drosophila and fission yeast and in programmed DNA elimination in Tetrahymena.
We cloned ARGONAUTE4 (AGO4) from a screen for mutants that suppress silencing
of the Arabidopsis SUPERMAN(SUP) gene. The ago4-1 mutant reactivated silentSUP
alleles and decreased CpNpG and asymmetric DNA methylation as well as histone
H3 lysine-9 methylation. In addition,ago4-1 blocked histone and DNA methylation
and the accumulation of 25-nucleotide small interfering RNAs (siRNAs) that correspond
to the retroelement AtSN1. These results suggest that AGO4 and long siRNAs direct
chromatin modifications, including histone methylation and non-CpG DNA methylation.
