text: Clustered regularly interspaced short palindromic repeats - CRISPR-associated
protein (CRISPR-Cas) systems are a critical component of the bacterial adaptive
immune response. Since the discovery that they can be reengineered as programmable
RNA-guided nucleases, there has been significant interest in using these systems
to perform diverse and precise genetic manipulations. Here, we outline recent
advances in the mechanistic understanding of CRISPR-Cas9, how these findings have
been leveraged in the rational redesign of Cas9 variants with altered activities,
and how these novel tools can be exploited for biotechnology and therapeutics.
We also discuss the potential of the ubiquitous, yet often-overlooked, multisubunit
CRISPR effector complexes for large-scale genomic deletions. Furthermore, we highlight
how future structural studies will bolster these technologies.

text: In the evolutionary arms race against phage, bacteria have assembled a diverse
arsenal of antiviral immune strategies. While the recently discovered DISARM (Defense
Island System Associated with Restriction-Modification) systems can provide protection
against a wide range of phage, the molecular mechanisms that underpin broad antiviral
targeting but avoiding autoimmunity remain enigmatic. Here, we report cryo-EM
structures of the core DISARM complex, DrmAB, both alone and in complex with an
unmethylated phage DNA mimetic. These structures reveal that DrmAB core complex
is autoinhibited by a trigger loop (TL) within DrmA and binding to DNA substrates
containing a 5′ overhang dislodges the TL, initiating a long-range structural
rearrangement for DrmAB activation. Together with structure-guided in vivo studies,
our work provides insights into the mechanism of phage DNA recognition and specific
activation of this widespread antiviral defense system.

text: CRISPR-Cas systems are adaptive immune systems that protect prokaryotes from
foreign nucleic acids, such as bacteriophages. Two of the most prevalent CRISPR-Cas
systems include type I and type III. Interestingly, the type I-D interference
proteins contain characteristic features of both type I and type III systems.
Here, we present the structures of type I-D Cascade bound to both a double-stranded
(ds)DNA and a single-stranded (ss)RNA target at 2.9 and 3.1 Å, respectively. We
show that type I-D Cascade is capable of specifically binding ssRNA and reveal
how PAM recognition of dsDNA targets initiates long-range structural rearrangements
that likely primes Cas10d for Cas3′ binding and subsequent non-target strand DNA
cleavage. These structures allow us to model how binding of the anti-CRISPR protein
AcrID1 likely blocks target dsDNA binding via competitive inhibition of the DNA
substrate engagement with the Cas10d active site. This work elucidates the unique
mechanisms used by type I-D Cascade for discrimination of single-stranded and
double stranded targets. Thus, our data supports a model for the hybrid nature
of this complex with features of type III and type I systems.

text: CRISPR–Cas9 as a programmable genome editing tool is hindered by off-target
DNA cleavage1,2,3,4, and the underlying mechanisms by which Cas9 recognizes mismatches
are poorly understood5,6,7. Although Cas9 variants with greater discrimination
against mismatches have been designed8,9,10, these suffer from substantially reduced
rates of on-target DNA cleavage5,11. Here we used kinetics-guided cryo-electron
microscopy to determine the structure of Cas9 at different stages of mismatch
cleavage. We observed a distinct, linear conformation of the guide RNA–DNA duplex
formed in the presence of mismatches, which prevents Cas9 activation. Although
the canonical kinked guide RNA–DNA duplex conformation facilitates DNA cleavage,
we observe that substrates that contain mismatches distal to the protospacer adjacent
motif are stabilized by reorganization of a loop in the RuvC domain. Mutagenesis
of mismatch-stabilizing residues reduces off-target DNA cleavage but maintains
rapid on-target DNA cleavage. By targeting regions that are exclusively involved
in mismatch tolerance, we provide a proof of concept for the design of next-generation
high-fidelity Cas9 variants.

text: The first X-ray pulsar, Cen X-3, was discovered 50 yr ago. Radiation from
such objects is expected to be highly polarized due to birefringence of plasma
and vacuum associated with propagation of photons in the presence of the strong
magnetic field. Here we present results of the observations of Cen X-3 performed
with the Imaging X-ray Polarimetry Explorer. The source exhibited significant
flux variability and was observed in two states different by a factor of ∼20 in
flux. In the low-luminosity state, no significant polarization was found in either
pulse phase-averaged (with a 3σ upper limit of 12%) or phase-resolved (the 3σ
upper limits are 20%–30%) data. In the bright state, the polarization degree of
5.8% ± 0.3% and polarization angle of 49fdg6 ± 1fdg5 with a significance of about
20σ were measured from the spectropolarimetric analysis of the phase-averaged
data. The phase-resolved analysis showed a significant anticorrelation between
the flux and the polarization degree, as well as strong variations of the polarization
angle. The fit with the rotating vector model indicates a position angle of the
pulsar spin axis of about 49° and a magnetic obliquity of 17°. The detected relatively
low polarization can be explained if the upper layers of the neutron star surface
are overheated by the accreted matter and the conversion of the polarization modes
occurs within the transition region between the upper hot layer and a cooler underlying
atmosphere. A fraction of polarization signal can also be produced by reflection
of radiation from the neutron star surface and the accretion curtain.

text: Using observations of X-ray pulsar Hercules X-1 by the Imaging X-ray Polarimetry
Explorer we report a highly significant (>17σ) detection of the polarization signal
from an accreting neutron star. The observed degree of linear polarization of
~10% is far below theoretical expectations for this object, and stays low throughout
the spin cycle of the pulsar. Both the degree and angle of polarization exhibit
variability with the pulse phase, allowing us to measure the pulsar spin position
angle 57(2) deg and the magnetic obliquity 12(4) deg, which is an essential step
towards detailed modelling of the intrinsic emission of X-ray pulsars. Combining
our results with the optical polarimetric data, we find that the spin axis of
the neutron star and the angular momentum of the binary orbit are misaligned by
at least ~20 deg, which is a strong argument in support of the models explaining
the stability of the observed superorbital variability with the precession of
the neutron star.

text: 'Magnetars are neutron stars with ultrastrong magnetic fields, which can be
observed in x-rays. Polarization measurements could provide information on their
magnetic fields and surface properties. We observed polarized x-rays from the
magnetar 4U 0142+61 using the Imaging X-ray Polarimetry Explorer and found a linear
polarization degree of 13.5 ± 0.8% averaged over the 2– to 8–kilo–electron volt
band. The polarization changes with energy: The degree is 15.0 ± 1.0% at 2 to
4 kilo–electron volts, drops below the instrumental sensitivity ~4 to 5 kilo–electron
volts, and rises to 35.2 ± 7.1% at 5.5 to 8 kilo–electron volts. The polarization
angle also changes by 90° at ~4 to 5 kilo–electron volts. These results are consistent
with a model in which thermal radiation from the magnetar surface is reprocessed
by scattering off charged particles in the magnetosphere.'

text: We use the Relativistic Precession Model (RPM) and quasi-periodic oscillation
(QPO) observations from the Rossi X-ray Timing Explorer to derive constraints
on the properties of the black holes that power these sources and to test general
relativity (GR) in the strong field regime. We build upon past techniques by using
pairs of simultaneously measured QPOs, rather than triplets, and by including
characteristic frequencies from the broad noise components of the power spectra
in our fits. We find the inclusion of these broad noise components causes an overestimate
in masses and underestimate in spins compared to values derived independently
from optical spectra. We extend the underlying space-time metric to constrain
potential deviations from the predictions of GR for astrophysical black holes.
To do this, we modify the RPM model to a Kerr–Newman–deSitter space-time and model
changes in the radial, ecliptic, and vertical frequencies. We compare our models
with X-ray data of XTE J1550-564 and GRO J1655-40 using robust statistical techniques
to constrain the parameters of the black holes and the deviations from GR. For
both sources, using QPO and characteristic frequency data, we constrain particular
deviations from GR to be less than one part per thousand.

text: Of more than a thousand known cataclysmic variables (CVs), where a white dwarf
is accreting from a hydrogen-rich star, only a dozen have orbital periods below
75 minutes1,2,3,4,5,6,7,8,9. One way to achieve these short periods requires the
donor star to have undergone substantial nuclear evolution before interacting
with the white dwarf10,11,12,13,14, and it is expected that these objects will
transition to helium accretion. These transitional CVs have been proposed as progenitors
of helium CVs13,14,15,16,17,18. However, no known transitional CV is expected
to reach an orbital period short enough to account for most of the helium CV population,
leaving the role of this evolutionary pathway unclear. Here we report observations
of ZTF J1813+4251, a 51-minute-orbital-period, fully eclipsing binary system consisting
of a star with a temperature comparable to that of the Sun but a density 100 times
greater owing to its helium-rich composition, accreting onto a white dwarf. Phase-resolved
spectra, multi-band light curves and the broadband spectral energy distribution
allow us to obtain precise and robust constraints on the masses, radii and temperatures
of both components. Evolutionary modelling shows that ZTF J1813+4251 is destined
to become a helium CV binary, reaching an orbital period under 20 minutes, rendering
ZTF J1813+4251 a previously missing link between helium CV binaries and hydrogen-rich
CVs.

text: This year, a new era of observations of compact objects in X-ray polarization
is commencing. Among the key targets for the Imaging X-ray Polarimetry Explorer
mission are the magnetars 4U 0142+61 and 1RXS J170849.0-400910. Here, we present
detailed predictions of the expected polarization from these sources that incorporate
realistic models of emission physics at the surface (gaseous or condensed), the
temperature distribution on the surface, general relativity, quantum electrodynamics,
and scattering in the magnetosphere, accounting for the broad-band spectral energy
distribution from below 1 keV to nearly 100 keV. We find that either atmospheres
or condensed surfaces can account for the emission at a few keV. In both cases,
either a small hot polar cap or scattering is required to account for the emission
at 5–10 keV and, above 10 keV, scattering by a hard population of electrons can
account for the rising power in the hard X-rays observed in many magnetars in
quiescence. Although these different scenarios result in very similar spectral
energy distributions, they generate dramatically different polarization signatures
from 2 to 8 keV, which is the range of sensitivity of the Imaging X-ray Polarimetry
Explorer. Observations of these sources in X-ray polarization will therefore probe
the emission from magnetars in an essentially new way.

text: It has been recently suggested that white dwarfs generate magnetic fields
in a process analogous to the Earth. The crystallization of the core creates a
compositional inversion that drives convection, and combined with rotation, this
can sustain a magnetic dynamo. We reanalyse the dynamo mechanism, arising from
the slow crystallization of the core, and find convective turnover times tconv
of weeks to months – longer by orders of magnitude than previously thought. With
white dwarf spin periods P ≪ tconv, crystallization-driven dynamos are almost
always in the fast-rotating regime, where the magnetic field B is at least in
equipartition with the convective motion and is possibly further enhanced by a
factor of B ∝ (tconv/P)1/2, depending on the assumed dynamo scaling law. We track
the growth of the crystallized core using MESA and compute the magnetic field
B(Teff) as a function of the white dwarf’s effective temperature Teff. We compare
this prediction with observations and show that crystallization-driven dynamos
can explain some – but not all – of the ∼MG magnetic fields measured for single
white dwarfs, as well as the stronger fields measured for white dwarfs in cataclysmic
variables, which were spun up by mass accretion to short P. Our B(Teff) curves
might also explain the clustering of white dwarfs with Balmer emission lines around
Teff ≈ 7500 K.

text: The maximum mass of a star that can produce a white dwarf (WD) is an important
astrophysical quantity. One of the best approaches to establishing this limit
is to search for WDs in young star clusters in which only massive stars have had
time to evolve and where the mass of the progenitor can be established from the
cooling time of the WD together with the age of the cluster. Searches in young
Milky Way clusters have not thus far yielded WD members more massive than about
1.1 M⊙, well below the Chandrasekhar mass of 1.38 M⊙, nor progenitors with masses
in excess of about 6 M⊙. However, the hunt for potentially massive WDs that escaped
their cluster environs is yielding interesting candidates. To expand the cluster
sample further, we used HST to survey four young and massive star clusters in
the Magellanic Clouds for bright WDs that could have evolved from stars as massive
as 10 M⊙. We located five potential WD candidates in the oldest of the four clusters
examined, the first extragalactic single WDs thus far discovered. As these hot
WDs are very faint at optical wavelengths, final confirmation will likely have
to await spectroscopy with 30 m class telescopes.

text: Over a dozen millisecond pulsars are ablating low-mass companions in close
binary systems. In the original ‘black widow’, the eight-hour orbital period eclipsing
pulsar PSR J1959+2048 (PSR B1957+20)1, high-energy emission originating from the
pulsar2 is irradiating and may eventually destroy3 a low-mass companion. These
systems are not only physical laboratories that reveal the interesting results
of exposing a close companion star to the relativistic energy output of a pulsar,
but are also believed to harbour some of the most massive neutron stars4, allowing
for robust tests of the neutron star equation of state. Here we report observations
of ZTF J1406+1222, a wide hierarchical triple hosting a 62-minute orbital period
black widow candidate, the optical flux of which varies by a factor of more than
ten. ZTF J1406+1222 pushes the boundaries of evolutionary models5, falling below
the 80-minute minimum orbital period of hydrogen-rich systems. The wide tertiary
companion is a rare low-metallicity cool subdwarf star, and the system has a Galactic
halo orbit consistent with passing near the Galactic Centre, making it a probe
of formation channels, neutron star kick physics6 and binary evolution.

text: We determine the distribution of cooling ages of massive Gaia EDR3 white dwarfs
identified with over 90 per cent probability within 200 pc and with mass in the
range 0.95–1.25 M⊙. Using three sets of publicly available models, we consider
sub-samples of these white dwarfs sorted into three equally spaced mass bins.
Under the assumption of a constant white dwarf formation rate, we find an excess
of white dwarfs, both along the Q branch and below it, corresponding respectively
to stars that are in the process of freezing and those that are completely frozen.
We compare the cooling age distributions for each of these bins to the recently
determined time-varying star formation rate of Gaia DR2 main sequence stars. For
white dwarfs in the two lightest mass bins, spanning the mass range 0.95–1.15
M⊙, we find that the cumulative cooling age distribution is statistically consistent
with the expectation from the star formation rate. For white dwarfs in the heaviest
mass bin, 1.15–1.25 M⊙, we find that their cumulative distribution is inconsistent
with the star formation rate for all of the models considered; instead, we find
that their cooling age distribution is well fitted by a linear combination of
the distribution expected for single stellar evolution products and the distribution
expected for double white dwarf merger products when approximately 40–50 per cent
of the 1.15–1.25 M⊙ white dwarfs that formed over the past 4 Gyr are produced
through double white dwarf mergers.

text: We searched through the entire Gaia EDR3 candidate white dwarf catalog for
stars with proper motions and positions that are consistent with them having escaped
from the Alpha Persei cluster within the past 81 Myr, the age of the cluster.
In this search we found five candidate white dwarf escapees from Alpha Persei
and obtained spectra for all of them. We confirm that three are massive white
dwarfs sufficiently young to have originated in the cluster. All these are more
massive than any white dwarf previously associated with a cluster using Gaia astrometry,
and possess some of the most massive progenitors. In particular, the white dwarf
Gaia EDR3 4395978097863572, which lies within 25 pc of the cluster center, has
a mass of about 1.20 solar masses and evolved from an 8.5 solar-mass star, pushing
the upper limit for white dwarf formation from a single massive star, while still
leaving a substantial gap between the resulting white dwarf mass and the Chandrasekhar
mass.

text: We search through an eight million cubic parsec volume surrounding the Pleiades
star cluster and the Sun to identify both the current and past members of the
Pleiades cluster within the Gaia EDR3 data set. We find nearly 1300 current cluster
members and 289 former cluster candidates. Many of these candidates lie well in
front of or behind the cluster from our point of view, so formerly they were considered
cluster members, but their parallaxes put them more than 10 pc from the center
of the cluster today. Over the past 100 Myr we estimate that the cluster has lost
twenty percent of its mass including two massive white dwarf stars and the α2
Canum Venaticorum type variable star, 41 Tau. All three white dwarfs associated
with the cluster are massive (1.01–1.06 M⊙) and have progenitors with main-sequence
masses of about six solar masses. Although we did not associate any giant stars
with the cluster, the cooling time of the oldest white dwarf of 60 Myr gives a
firm lower limit on the age of the cluster.

text: Apolipoprotein A‐I (apoA‐I) has a key function in the reverse cholesterol
transport. However, aggregation of apoA‐I single point mutants can lead to hereditary
amyloid pathology. Although several studies have tackled the biophysical and structural
consequences introduced by these mutations, there is little information addressing
the relationship between the evolutionary and structural features that contribute
to the amyloid behavior of apoA‐I. We combined evolutionary studies, in silico
mutagenesis and molecular dynamics (MD) simulations to provide a comprehensive
analysis of the conservation and pathogenic role of the aggregation‐prone regions
(APRs) present in apoA‐I. Sequence analysis demonstrated that among the four amyloidogenic
regions described for human apoA‐I, only two (APR1 and APR4) are evolutionary
conserved across different species of Sarcopterygii. Moreover, stability analysis
carried out with the FoldX engine showed that APR1 contributes to the marginal
stability of apoA‐I. Structural properties of full‐length apoA‐I models suggest
that aggregation is avoided by placing APRs into highly packed and rigid portions
of its native fold. Compared to silent variants extracted from the gnomAD database,
the thermodynamic and pathogenic impact of amyloid mutations showed evidence of
a higher destabilizing effect. MD simulations of the amyloid variant G26R evidenced
the partial unfolding of the alpha‐helix bundle with the concomitant exposure
of APR1 to the solvent, suggesting an insight into the early steps involved in
its aggregation. Our findings highlight APR1 as a relevant component for apoA‐I
structural integrity and emphasize a destabilizing effect of amyloid variants
that leads to the exposure of this region.

text: Martin Loose studied chemistry at the University of Heidelberg, Germany. He
then joined Petra Schwille's group at the Max Planck Institute of Molecular Cell
Biology and Genetics in Dresden, where he obtained his PhD degree in 2010 for
work on self-organization and pattern formation in the bacterial Min protein system.
He then moved to Tim Mitchison's lab at Harvard Medical School, Boston, USA for
his postdoc, funded by Human Frontier Science Program (HSFP) and European Molecular
Biology Organization (EMBO) long-term fellowships; there, he discovered that the
bacterial cell division proteins FtsA and FtsZ self-organize into dynamic cytoskeletal
patterns. Martin established his independent research group at the Institute of
Science and Technology (IST) Austria in 2015, supported by an European Research
Council (ERC) starting grant and HFSP Young Investigator Grant. His lab studies
the self-organization of bacterial cell division and small GTPase networks.

text: We compare the Manin-type conjecture for Campana points recently formulated
by Pieropan, Smeets, Tanimoto and Várilly-Alvarado with an alternative prediction
of Browning and Van Valckenborgh in the special case of the orbifold (P1,D), where
D=1/2[0]+1/2[1]+1/2[∞]. We find that the two predicted leading constants do not
agree, and we discuss whether thin sets could explain this discrepancy. Motivated
by this, we provide a counterexample to the Manin-type conjecture for Campana
points, by considering orbifolds corresponding to squareful values of binary quadratic
forms.
