SSTMNet: Spectral-Spatio-Temporal and Multiscale Deep Network for EEG-Based Motor Imagery Classification

open access: yesMathematics
Motor impairment is a critical health issue that restricts disabled people from living their lives normally and with comfort. Detecting motor imagery (MI) in electroencephalography (EEG) signals can make their lives easier.

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Extraction and Coordination Chemistry of Mo(Ⅵ)/U(Ⅵ) With Unilateral Derivatized Phenanthroline Amide Ligands

open access: yesHe huaxue yu fangshe huaxue
Medical radioactive isotopes play a very important role in disease diagnosis and treatment, with 99Tcm drugs being widely used in disease diagnosis. 99Tcm is primarily obtained from its parent nuclide, 99Mo, through a 99Mo/99Tcm generator. Currently, the

TME/NIR Dual‐Responsive Zinc‐Based Targeted Nanoagonist for Multimodal Amplification of STING‐Mediated Cancer Immunotherapy

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
A multifunctional nanoagonist (cDZ@IP) enables nano‐metabolite–driven multimodal activation of the STING pathway and enhanced immune recognition, achieving potent antitumor immunity and suppressing tumor growth and metastasis. This strategy highlights the rational design of therapeutic metabolites and establishes a new paradigm bridging nanomedicine ...

Intrinsically Mitochondria‐Targeting Nanozyme via Coordination‐Assembly of Natural Quercetin for Cascade Antioxidant Therapy of Cerebral Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, Volume 13, Issue 50, 7 September 2026.
This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Altered Neurovascular Coupling Dynamics During Dobutamine‐Induced Acute Stress

open access: yesBrain and Behavior, Volume 16, Issue 9, September 2026.
ABSTRACT Background Neurovascular coupling (NVC) is essential for regulating brain metabolism and energy supply and may be altered under acute stress. This study aimed to investigate how acute stress induced by dobutamine affects NVC. Materials and methods This study enrolled 38 healthy participants undergoing a resting‐state fMRI scan and an arterial ...

Novel Noninvasive Broad‐Spectrum Infrared Treatment of Ulcerative Colitis by Modulating T‐Cell Relocation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
A novel graphene‐based broad‐spectrum infrared (BSIR) device is developed for the noninvasive treatment of ulcerative colitis (UC). BSIR irradiation effectively alleviates colonic inflammation and accelerates mucosal recovery by inducing the systemic relocation of T lymphocytes to the spleen.

Deletion of Astrocytic TNFR1 Attenuates Hyperexcitability and Initiation of Epileptogenesis

open access: yesGlia, Volume 74, Issue 9, September 2026.
Inducible, astrocyte‐specific deletion of TNFR1 reduces basal EEG spectral power. Loss of astrocytic TNFR1 attenuates acute seizure activity in two distinct experimental models of epilepsy. Deletion of TNFR1 in astrocytes limits epilepsy development and hippocampal pathology in a mouse model of temporal lobe epilepsy with hippocampal sclerosis ...

Cortical Specification of a Fast Fourier Transform Supports a Convolution Model of Visual Perception [PDF]

open access: yes, 2012
Currently, the full extent of the role Fourier analysis plays in biological vision is unclear. Although we have examples of sensory organs that perform Fourier transforms, e.g.

Fossils as cultural heritage: Scientific, commercial and legislative issues

open access: yesGeology Today, Volume 42, Issue 5, Page 263-272, September/October 2026.
Fossils are among the principal sources for understanding the history of life through ‘Deep Time’ and can inform projections of biotic responses to environmental change. Despite a widespread recognition of the scientific, historical and communication significance of fossils in our culture, their role as part of our cultural heritage is still far from ...
