Abstract Recent discovery of emergent magnetism in van der Waals magnetic materials (vdWMM) has broadened the material space for developing spintronic devices for energy-efficient computation. While there has been appreciable progress in vdWMM discovery, a solution for non-volatile, deterministic switching of vdWMMs at room temperature has been missing, limiting the prospects of their adoption into commercial spintronic devices. Here, we report the first demonstration of current-controlled non-volatile, deterministic magnetization switching in a vdW magnetic material at room temperature. We have achieved spin-orbit torque (SOT) switching of the PMA vdW ferromagnet Fe3GaTe2 using a Pt spin-Hall layer up to 320 K, with a threshold switching current density as low as $${J}_{{{{{{\rm{sw}}}}}}}=$$ J sw = 1.69 $$\times$$ × 106 A cm−2 at room temperature. We have also quantitatively estimated the anti-damping-like SOT efficiency of our Fe3GaTe2/Pt bilayer system to be $${\xi }_{{{{{{\rm{DL}}}}}}}=0.093$$ ξ DL = 0.093 , using the second harmonic Hall voltage measurement technique. These results mark a crucial step in making vdW magnetic materials a viable choice for the development of scalable, energy-efficient spintronic devices.

Paleomagnetism can elucidate the origin of inner core structure by establishing when crystallization started. The salient signal is an ultralow field strength, associated with waning thermal energy to power the geodynamo from core-mantle heat flux, followed by a sharp intensity increase as new thermal and compositional sources of buoyancy become available once inner core nucleation (ICN) commences. Ultralow fields have been reported from Ediacaran (~565 Ma) rocks, but the transition to stronger strengths has been unclear. Herein, we present single crystal paleointensity results from early Cambrian (~532 Ma) anorthosites of Oklahoma. These yield a time-averaged dipole moment 5 times greater than that of the Ediacaran Period. This rapid renewal of the field, together with data defining ultralow strengths, constrains ICN to ~550 Ma. Thermal modeling using this onset age suggests the inner core had grown to 50% of its current radius, where seismic anisotropy changes, by ~450 Ma. We propose the seismic anisotropy of the outermost inner core reflects development of a global spherical harmonic degree-2 deep mantle structure at this time that has persisted to the present day. The imprint of an older degree-1 pattern is preserved in the innermost inner core.

Cardiac neural crest must differentiate and migrate correctly to achieve proper cardiovascular development. Here, the authors use single cell analyses to show how these cells are altered non-autonomously by loss of Tbx1, the major gene for 22q11.2 deletion syndrome.

An intracellular antenna that can truly enable probing, modulation or augmentation of biological cells remains an unmet challenge. Here, the authors present the Cell Rover, a magnetostrictive antenna that operates wirelessly inside a living cell and is compatible with 3D biological systems.

New single crystal paleointensity data show that the geomagnetic field was renewed in the early Cambrian after near collapse in the Ediacaran Period. This implies that the innermost/outermost structure of the inner core formed 450 million yrs. ago.

Perturbations of the cardiopharyngeal mesoderm can lead to congenital defects in individuals with 22q11.2 deletion syndrome. Here the authors use single cell RNA-sequencing to identify a multilineage primed population within the mesoderm, marked by Tbx1, which has bipotent properties to form cardiac and branchiomeric muscle cells.

This study describes how the geomagnetic axial dipole dominance of Earth’s magnetic field remained stable through large parts of the geological time. Since other characteristics of the geomagnetic field have changed substantially on the same timescales, this new observation provides a challenge for future core modeling studies.

IL-17 is a pro-inflammatory molecule that can also regulate neural circuit function. Here the authors use C. elegans to show that the paracaspase MALT-1 lies downstream of IL-17 signaling and regulates many aspects of C. elegans biology, including escape behavior, associative learning, immunity and longevity.

Controversy surrounds the fixity of both hotspots and large low shear velocity provinces (LLSVPs). Here, the authors present new paleomagnetic data to show that the great bend in the Hawaiian-Emperor seamount chain can be attributed to mantle plume motion and that LLSVPs are mobile.

On-chip spectrometers typically have limited spectral channels and low signal to noise ratios. Here the authors introduce a digital architecture that uses switches to change the interferometer path lengths, enabling exponentially more spectral channels per circuit element and lower noise by leveraging a machine learning reconstruction algorithm.

AMPK regulates cellular energy balance using its γ subunit as an energy sensor of cellular AMP and ADP to ATP ratios. Here, the authors show that γ2 AMPK activation lowers heart rate by reducing the activity of pacemaker cells, whereas loss of γ2 AMPK increases heart rate and prevents the adaptive bradycardia of endurance training in mice.

Synaptic plasticity is the neuronal mechanism underlying learning. Here the authors construct biophysical models of pyramidal neurons that reproduce observed plasticity gradients along the dendrite and show that dendritic spike dependent LTP which is predominant in distal sections can prolong memory retention.

Epithelial progenitor cell growth in the second heart field contributes to heart morphogenesis but how this is regulated at the tissue level is unclear. Here, the authors show that cell elongation, polarized actomyosin and nuclear YAP/TAZ drive epithelial growth and correlate with mechanical tension.

The naked mole-rat exhibits an exceptional resistance to cancer. Here, the authors show that induced pluripotent stem cells derived from the naked mole-rat lack teratoma-forming tumorigenicity due to a naked mole-rat-specific ARF-dependent tumour-suppression mechanism.

Ferromagnetic nanowires act as conduits for magnetic domain walls which may in principle be used to encode and propagate information. Here, the authors present current-based nanowire domain wall logic prototypes with operational properties required for real devices.
