🧠 Cognitive Control in the Prefrontal Cortex Follows a Temporal Order

Source: Nature Neuroscience
What holds
Neurons in the prefrontal cortex fall into a temporal hierarchy. Slow, steady-firing neurons sit higher in the chain, integrating information over time. Fast, bursty neurons operate lower, executing immediate decisions. Hierarchy follows timing rather than location.
Why this matters
If control is organized by tempo, then some cognitive disorders may stem from timing mismatches rather than structural damage. When slow integrators and fast responders fall out of sync, planning and perception unravel without anything being visibly “broken.”
🚀 PubMedAI API Is Now Live
We’re excited to announce that the PubMedAI API is officially live and ready to be integrated into your research workflows, applications, and internal tools.
With the PubMedAI API, you can programmatically access literature search, conversational querying, and structured research report generation — all built on top of biomedical and life science–focused retrieval and reasoning. Whether you’re developing research tools, automating evidence screening, or enhancing internal knowledge systems, the API is designed to be flexible, transparent, and research-oriented.

To support early adopters, the first two months of API access are completely free. This is an opportunity to explore real-world use cases, test integrations, and evaluate how PubMedAI fits into your existing pipeline with no upfront cost.
Please note that this API is currently in beta test stage. If you’re interested in getting access or want to discuss potential use cases, feel free to reach out to us directly. We’re actively listening to early users and welcome feedback to help guide future improvements and feature development.

🧪 Mistaking Fat for Plastic: The "Contamination" Crisis

Source: The Guardian
The Findings
The narrative that "microplastics are invading our brains" is facing a massive scientific recall. A new investigation reveals that Py-GC-MS (the gold standard detection method) often mistakes human lipids (fat) for polyethylene. Because the brain is ~60% fat, those viral studies claiming high plastic loads in dementia patients might just be measuring the patient's own tissue. Experts now suggest up to 50% of high-impact papers could be riddled with these false positives.
Clinical Implication
We are witnessing a collision between high-velocity publishing and analytical reality. The contradiction is sharp: journals are incentivized to flag new dangers, but the chemistry tells a different story. The core technical flaw is that our instruments struggle to distinguish biological fat from synthetic polymers under heat. This shifts the burden of proof entirely. The priority now isn't just "finding" plastic; it's mastering the "exclusion of interference." Unless labs rigorously run blank samples to subtract biological noise, any claim of "plastic in the brain" is statistically suspect.
🍄 Blocking Flippase Reverses Fungal Resistance

Source: Cell
What We Now Know
Drug-resistant Candida is becoming a nightmare because fungi evolve faster than we can invent new drug classes. This study identifies Butyrolactol A, a marine-derived molecule that inhibits fungal "flippase" enzymes. By blocking flippase, it disrupts the lipid asymmetry of the fungal membrane, making resistant strains vulnerable to Caspofungin again.
Why This Changes Everything
It’s a "resurrection" strategy. Instead of spending billions finding a new killer molecule, we can use this potentiator to make our old, failing drugs lethal again. It turns a resistance mechanism into a vulnerability, effectively reopening the therapeutic window for echinocandins.

Can Diet Drive Remission? Rethinking Crohn’s Disease Treatment
For decades, Crohn’s disease has been managed primarily through pharmacological immunosuppression. But a growing body of evidence now suggests that diet itself can directly influence disease activity—not just symptoms.
Recent randomized controlled trials show that fasting-mimicking diets and the Crohn’s Disease Exclusion Diet (CDED) can induce clinical remission in patients with mild-to-moderate Crohn’s disease, offering a viable non-pharmacological strategy.
🔬 These dietary approaches are associated with several converging biological changes. Patients adhering to structured dietary interventions show improvements in clinical outcomes, accompanied by reduced intestinal inflammation and measurable shifts in gut microbiota composition.

Can Diet Really Change the Course of Crohn’s Disease?
Dietary therapy is no longer just a complementary idea in inflammatory bowel disease research. But how much do you actually know about the evidence behind fasting-mimicking diets, exclusion diets, and whole-food strategies?
🔍 Test your understanding in our latest quiz, based on a deep dive into randomized controlled trials and mechanistic insights exploring dietary interventions in mild-to-moderate Crohn’s disease.
Think you know which dietary strategy delivers the greatest therapeutic benefit — and why?
The answers may challenge long-held assumptions about nutrition and immune disease.

🔬Must-Read Research: The Blind Spot in Consciousness Theory
The study argues that while we are conscious of information content such as sensory inputs, thoughts, we are constitutionally blind to the processes that generate them. For example, the "will to act" is merely a feedback copy of a motor command, not the actual mechanism of decision-making.
