A 2026 PLOS One computational study linked Trichostatin A to 949 predicted targets and 8 machine-learning-selected Alzheimer’s disease core genes, but 100 ns molecular dynamics simulations suggested the compound did not stably bind those candidate proteins.1 That makes the result more useful as an epigenetic network hypothesis than as evidence for a near-term Alzheimer’s drug. …
A self-localized ultrafast pencil beam is not a brain treatment, but it could become useful imaging infrastructure for neuroscience and drug-delivery research. In an arXiv preprint, Cao et al. generated a stable ultrafast beam inside a standard multimode fiber and used it for volumetric multiphoton imaging of intact mouse enteric nervous tissue and a live …
A 2026 mouse study found that long-term CoQ10 exposure reduced working-memory errors in Purkinje-cell-specific Drp1-deficient mice, tying the behavioral rescue to Coa6 binding and support for mitochondrial respiratory-chain function.1 The result supports a narrow mechanistic CoQ10-Coa6 pathway under neuronal mitochondrial dysfunction while leaving human memory-supplement claims untested. Research Highlights Working memory improved in a mouse …
A 2025 Science Advances mouse study found a more brain-dependent metformin mechanism than the usual liver-gut framing suggests: low-dose metformin lost its glucose-lowering effect when brain Rap1 signaling could not be reduced, and 36 of 47 ventromedial-hypothalamus SF1 neurons responded directly to metformin.1 Research Highlights Low-dose metformin needed brain Rap1: Control mice lowered glucose after …
A 2022 Nature Communications study used non-contrast 3D T2-FLAIR magnetic resonance imaging (MRI) to map human brain lymphatic signals in living people, including apparent channels from cranial nerves and skull-base structures toward cervical lymph nodes. Research Highlights Non-contrast MRI visualized lymphatic-like brain drainage: Albayram et al. identified dorsal dural signals near venous sinuses and ventral …
A 2026 medRxiv preprint involving 65 early subacute stroke survivors found that a composite cerebral small-vessel disease MRI score predicted 90-day cognitive recovery more reliably than any single input marker.1 Lower baseline burden predicted higher follow-up Montreal Cognitive Assessment scores (β = −0.19; p = 0.009) and remained associated after baseline cognition was included (β …
A 2026 mouse study found that complete IL-6 deficiency worsened motor dysfunction and dopaminergic injury in MPTP and alpha-synuclein A53T Parkinson’s disease models, with earlier and broader vulnerability in female knockout mice.1 The result cuts against a simple “less inflammation is always better” frame: recombinant IL-6 partly improved MPTP-induced motor dysfunction and striatal dopaminergic terminal …
