Detecting melanoma before it becomes visible is a major challenge in dermatology. Now, with researchers from Université de Montréal, scientists at Université du Québec's Institut national de la recherche scientifique (INRS) have developed a promising solution.

BackgroundRepetitive Transcranial Magnetic Stimulation (rTMS) is an FDA-approved, non-invasive treatment for Major Depressive Disorder (MDD). rTMS has a favorable safety profile, however, headaches are a common side effect. It is unclear which patients may be at greatest risk for headache, which device parameters might be associated with headache, and whether occurrence of headaches during rTMS a…

Brain imaging reveals that young women who self-harm possess a distinct neurological vulnerability online. Unlike healthy peers, their brain's reward centers become highly engaged by negative comments, a trait that correlates with problematic social media use.

Nature Neuroscience, Published online: 25 May 2026; doi:10.1038/s41593-026-02285-1 By combining magnetoencephalography and eye tracking, this study sheds light on why people fixate on some parts of natural scenes longer than others. Rather than visual complexity, fixation durations are affected by memory encoding.

Nature Neuroscience, Published online: 25 May 2026; doi:10.1038/s41593-026-02314-z Lozano et al. show that REM sleep is gated by low-dimensional brainstem network dynamics, in which opposing neuron populations across the midbrain and pons determine when transitions into REM sleep can occur.

BackgroundKawasaki disease (KD) is an acute systemic vasculitis predominantly affecting children under 5 years of age. Its pathogenesis remains incompletely understood, and the lack of specific diagnostic biomarkers during the acute phase poses substantial challenges to clinical diagnosis. Such diagnostic uncertainty often results in missed or delayed cases, leading to lost therapeutic opportunit…

BackgroundMost studies on social exclusion adopt virtual paradigms focusing on unilateral responses, while neglecting real-world face-to-face interaction and its neural basis. Functional near-infrared spectroscopy (fNIRS) hyperscanning allows recording of interpersonal neural synchronization (INS) during dyadic interaction, providing a novel approach for investigating interpersonal cooperation.Me…

ObjectiveTo compare left vs. right steep turns in terms of workload-related neurophysiological signatures using electroencephalogram (EEG) and machine learning.MethodsThirty-seven flight cadets performed one left and one right steep turn in an SR20 desktop flight simulator while a 32-channel EEG (Emotiv EPOC Flex 32) was recorded. From 2-s sliding windows (50% overlap), 800 features per window we…

This study evaluated broth microdilution (BMD) and fluorescence PCR melting curve analysis (MeltPro MTB/PZA, targeting pncA mutations) for detecting pyrazinamide (PZA) resistance-associated mutations in rifampicin-resistant tuberculosis (RR-TB). PZA susceptibility was assessed in RR-TB isolates from patients at TB prevention and control institutions and at designated hospitals in Beijing. Whole-g…

Scientists in South Africa are exploring a surprising new way to detect one of the world’s deadliest cancers: saliva. Researchers at the Sydney Brenner Institute for Molecular Bioscience at Wits University believe that bacteria living in the mouth may provide important clues about esophageal squamous cell carcinoma, a dangerous form of cancer that affects the […] The post Simple Saliva Test May H…

Research team at Macau University of Science and Technology is developing AI-driven early-warning systems that detect weak disease signals earlier, speed up cancer diagnosis, and support more precise treatment decisions across cancer, aging, vision, and women's health.

IntroductionFibromyalgia (FM) is a chronic pain disorder with unclear neuroanatomical basis, as previous studies largely relied on volumetric measures insensitive to cortical surface morphology. This multi-parametric surface-based morphometry study examined cortical thickness (CT), fractal dimension (FD), gyrification index (GI), and sulcal depth (SD) in FM.MethodsThirty-three female FM patients …

IntroductionThis study compared the clinical efficacy of laparoscopic cervical cerclage (LAC) and transvaginal cervical cerclage (TVC) in treating cervical insufficiency (CI) patients after hysteroscopic adhesiolysis for intrauterine adhesions (IUA).MethodsA total of 170 eligible patients (66 in the LAC group, 104 in the TVC group) admitted from Jan 2018 to Jan 2024 were retrospectively analyzed,…

Scientists have developed a new urine test that could make life much easier for men living with low-risk prostate cancer. According to a new study, the test may help many patients avoid painful and invasive prostate biopsies while still allowing doctors to find cancers that become more dangerous over time. The research was published in […] The post Simple urine test may change the future of prost…
