This is how faster than light signalling could work

In this video I explain why I think it’s wrong to believe that the speed of light is an impossible to overcome limit. I am afraid that this is the biggest mistake that physicists are making, that indeed our entire species is making. And it’s all due to physicists’ misunderstanding quantum mechanics.

Association of Interictal Respiratory Variability and Severity of Postictal Hypoxemia After Generalized Convulsive Seizures

In an observational cohort study based on the Atherosclerosis Risk in Communities-Neurocognitive Study (ARIC-NCS), the presence of lobar and mixed CMBs was associated with incident dementia. stroke.

BACKGROUND: Cerebral microbleeds (CMBs) are associated with dementia, but the impact of specific microbleed patterns (with distinct pathophysiologies) is unclear. Lobar CMBs commonly result from cerebral amyloid angiopathy (sometimes with cortical superficial siderosis [cSS]), while subcortical microbleeds indicate a hypertensive cause. This study investigates the association of CMB presence, patterns, and frequency with dementia risk. METHODS: Participants from the ARIC-NCS (Atherosclerosis Risk in Communities-Neurocognitive Study), a community-based longitudinal cohort, with a 3T research magnetic resonance imaging at visit 5 (2011–2013) without prior intracerebral hemorrhage or dementia, were included. CMB and cSS presence and location were evaluated using a T2 gradient-recalled echo sequence.

Intracellular bacteria modulate the immune microenvironment of oral squamous cell carcinoma

Wang et al. apply INVADEseq to probe intracellular bacteria in oral squamous cell carcinoma patients treated with neoadjuvant immunotherapy. They show that bacteria modulate immune efficacy, identify specific response predictors, and uncover the impact of bacteria on the communication between predictors and cDC1s.

Plasma p-tau217 Cutoffs, Kidney Function, BMI, and Anemia

Biologically informed plasma pTau217 thresholds improved diagnostic accuracy for amyloid PET positivity in patients with CKD and anemia vs a standard single cutoff, supporting cost-efficient biomarker implementation in AlzheimerDisease screening.

Question For plasma phosphorylated tau 217–based amyloid-β detection, does the strategy of using biological subgroup–specific optimal single cutoffs or a double cutoff better optimize diagnostic accuracy and cost efficiency?

Findings This cohort study found that subgroup-specific optimal cutoffs improved accuracy over the standard single cutoff, especially in chronic kidney disease (CKD) and anemia. Compared with a double cutoff, the optimal cutoff had similar or better accuracy in CKD with lower cost, whereas a double cutoff was slightly better in underweight and anemia but created intermediates; in obesity, a double cutoff remained superior.

Meaning Biologically optimized cutoffs offer a balanced, cost-efficient default, particularly in CKD and anemia, while a double cutoff retains advantages in obesity.

The E3-ome gene-centric compendium reveals the human E3 ligase landscape

Now online! The E3-ome defines the human repertoire of ubiquitin E3 ligases, creating a unified resource that maps their diversity across the ubiquitin and ubiquitin-like systems. By consolidating fragmented knowledge, this framework provides a foundation for studying ubiquitin signaling and accelerating discovery.

Spontaneous aging-associated inflammation and genome instability in the immune system of turquoise killifish

Turquoise killifish are naturally short-lived vertebrates that serve as a model system for aging. The authors show that killifish exhibit age-related transformation in the immune system, which rapidly develops inflammation, genome instability and functional decline.
