Advancing Dry Electroencephalography With Scalable, Soft, and Transcranial Magnetic Stimulation‐Compatible Ti3C2Tx MXene Electrodes for Research and Clinical‐Grade Applications

Advanced Science, EarlyView.
Dry soft Ti3C2Tx MXene electroencephalography (EEG) electrodes provide low impedance (2.1 ± 1.8 kΩ at 10 Hz), long‐term stability, and enable safe simultaneous EEG and transcranial magnetic stimulation (TMS). Across scalp sites, hair types, and recording paradigms, including steady state visual evoked potentials (SSVEP), clinical EEG, and mobile EEG ...

The Timing and Spectral Properties of the 2022 Outburst of SGR J1935+2154 Observed with NICER

The Astrophysical Journal
The magnetar SGR J1935+2154 entered a new active episode on 2022 October 10, with X-ray bursts and enhanced persistent emission. At the tail of a high burst rate interval, lasting several hours, radio bursts were detected, revealing the connection ...

Bimetallic Peroxide Nanocomposites‐Driven Redox Dyshomeostasis to Activate Sequential Cuproptosis and Pyroptosis for Amplified Tumor Immunotherapy

Advanced Science, EarlyView.
Hyaluronic acid‐modified bimetallic peroxide nanocomposites (MgO2‐CuO2@HA) are designed for synergistic tumor therapy. The nanocomposites release Mg2+, H2O2, and Cu2+ in tumor cells, induce cuproptosis via Cu+‐mediated protein aggregation, and activate pyroptosis through caspase‐1/gasdermin D pathways for inducing immunogenic cell death, collectively ...

On the Detection and Characterization of Quasiperiodic Oscillations in Astronomical Time Series: Gamma-Ray Burst X-Ray Light Curves as a Test Case

The Astrophysical Journal
The study of temporal properties of variable sources can elucidate their physical processes. In this context, we present a critical study comparing three approaches to periodic or quasiperiodic behavior: Gaussian process, power spectrum, and wavelet ...

Bioabsorbable Endovascular Adhesive Tape (BEAT) for Improving Vascular Regeneration

Advanced Science, EarlyView.
A bioabsorbable endovascular adhesive tape (BEAT) platform based on a hierarchical polyelectrolyte complex is developed to enhance drug delivery in the DCB system. The coating enables rapid transfer to the vessel, provides short‐term mechanical support, and promotes both immediate transfer and long‐term retention of drugs at the lesion site.

DCAF13 Safeguards Hematopoietic Stem Cells via RRS1‐Regulated Ribosome Biogenesis

Advanced Science, EarlyView.
This study establishes DCAF13 as an essential regulator for hematopoietic stem cell (HSC) function. Its deletion in mice causes lethal pancytopenia and HSC depletion. Mechanistically, DCAF13 interacts with RRS1 and mediates its non‐degradative K27‐linked ubiquitination, thereby stabilizing RRS1 to maintain ribosome biogenesis and protein translation ...
