Bio-degradation of poly(butylene adipate-co-terephthalate) is an attractive tactic but requires an effective hydrolytic enzyme. Here, the authors demonstrate that cutinases are highly potent PBAT-decomposing enzymes and their mechanism is proposed based on substrate-binding mode.
In this study, the authors perform a meta-analysis of COVID-19 vaccine effectiveness studies and compare observed protection against severe disease with model-based estimates of neutralising antibody titres. Their results show that SARS-CoV-2 antibody titres are predictive of protection against severe COVID-19 disease.
Transmembrane signaling is the core adaptation in nature that allows cells to communicate. Here, the authors engineer signaling through the lipid bilayer using chemical, synthetic receptors for their use in the design of artificial cells.
A nonreciprocal critical current is known as the superconducting diode effect (SDE). Here, the authors use SQUID-on-tip to study SDE in a EuS/Nb bilayer and find that the stray field from magnetized EuS creates screening currents in the Nb, which lead to SDE by affecting vortex flow dynamics.
Many transcriptomic pathways in the liver show circadian rhythms, which have been reported to be disrupted in aged mice. Here the authors report that the expression of transcription factor Egr-1 decreases and its rhythm is shifted with age in the liver of male mice, and that deletion of Egr-1 results in increased liver fat accumulation.
Space-charge layers are believed to profoundly influence the interfaces in all-solid-state Li batteries. Here, the authors provide atomic scale insights into this phenomenon, and discover that its impact could be fundamentally different from commonly believed.
Polarons are quasi-particles that emerge when impurity particle is mixed with the low-energy excitations of a medium. Here the authors study the case of atom-ion quantum mixtures and identify three separate bipolaronic regimes which can arise depending on the interaction range and strength.
The existence of multicellular systems relies on coordinated cell motion in three dimensions. Here, cell migration in rotating spherical tissues is shown to exhibit a collective mode with a single-wavelength velocity wave, which arises from the effect of curvature on the flocking behavior of cells on a spherical surface.
The weathering alkalinity flux from mid-latitudes to the ocean will be strongly altered by climate warming by 2100. Under different emissions scenarios either a strengthening or a weakening of the flux and thus of the oceanic CO2 buffer is predicted.
Early detection of multiple cancers through a single method could be clinically important. Here the authors report the diagnostic performance for early detection for multiple cancers using surface-enhanced Raman spectroscopy (SERS) profiles of exosomes from a single blood test and artificial intelligence in a retrospective study design.
Sliding and twisting of van der Waals layers can produce fascinating physical phenomena. Here, authors show that moiré polar domains in bilayer hBN give rise to a topologically non-trivial winding of the polarization field, forming networks of merons and antimerons.
Modification of RNA with m6A has been shown to be important during spermatogenesis. Here they identify post-transcriptional functions of PRRC2A, showing it promotes transcriptome transition from spermatogonia to spermatocytes and the translation of genes related to cell division.
Acid sphingomyelinase (ASM) is a sphingolipid metabolizing enzyme that catalyzes the hydrolysis of sphingomyelin to ceramide, and previous work has shown it is upregulated in models of Alzheimer’s disease. Here the authors demonstrate in a mouse model of Alzheimer’s disease that antibody-based immunotherapy targeting plasma ASM resulted in attenuated neuropathological features by suppressing pathogenic Th17 cells.
A superconducting diode effect was recently reported in Nb/V/Ta superlattices, but the mechanism is not yet clear. Here, the authors study non-reciprocal critical current in Al/InAs nanowires and propose a generic extrinsic mechanism involving field-generated diamagnetic currents, which may explain the earlier Nb/V/Ta results.
Anti-folate drugs, such as methotrexate, have been largely prohibited for pregnant women because of the teratogenic effect on their descendant. Here, the authors report a intergenerational mechanism by why paternal methotrexate exposure causes craniofacial defects on their offspring.
Glioblastoma is an immunologically cold tumour, with poor CD8 + T cell infiltration and enrichment in immunosuppressive tumour-associated myeloid cells. Here, the authors generate a bispecific lipid nanoparticle targeting CD47 and PD-L1, combined with a STING agonist, to promote anti-tumour immunity.
The role of dopamine in the cerebellum remains relatively unexplored. Here, the authors report a dopamine system in the cerebellum in mice, where Purkinje cells supply dopamine and Bergmann glia express D1 receptors. Activation of D1 receptors is found to modulate Purkinje cell activity and to affect locomotor and social behaviors.
Multiplexed imaging technologies can reveal the complex cellular and molecular profiles of tissue. Here, the authors develop and implement a denoising pipeline to significantly enhance imaging mass cytometry quality and improve single-cell analyses.
The authors used multi-disciplinary approaches to understand the structural mechanism underlying spontaneous aggregation of tau encoding an S320F FTD-tau mutant. Understanding the mechanisms of tau aggregation will help identify novel methods to regulate its misfolding.
Several strategies have been employed to enhance the tumor-targeting and anti-cancer properties of engineered bacteria. Here the authors describe the design of alternating magnetic field-manipulated bacteria engineered to release an anti-CD47 nanobody, promoting anti-tumor immune response in preclinical cancer models.
