TL;DR: In mice, strengthening the body's daily clock starting three days after a stroke, with an experimental clock drug or by limiting meals to the animals' active hours, led to smaller brain injuries and better walking. This is early animal research, not a t…

TL;DR: In a 2026 lab study, researchers looked at the chemical switches that turn genes on and off in medulloblastoma, a brain cancer that mostly affects children. Removing a protein called KDM2B slowed the growth of 2 of the cancer’s main types in lab dishes…

TL;DR: In a 2026 mouse study, researchers injected a toxic chemical into the eyes of mice to kill the nerve cells that carry vision to the brain, then treated some eyes with tiny particles carrying myricetin, a plant compound. Treated mice kept more of these c…

TL;DR: In a small 2026 mouse study, mice got a memory-disrupting drug for 7 days, some along with a steroid that raises blood sugar. Mice also given kola nut extract, from a West African seed that contains caffeine, did better on maze memory tests and had heal…

TL;DR: In a 2026 study, mice breathed a common surgical anesthetic gas for a few hours over several days. Afterward, molecules that turn genes up or down in the hippocampus, the brain’s memory center, had clearly shifted compared with mice that breathed none:…

TL;DR: Four weeks of being kept awake about 20 hours a day damaged memory and brain-cell connections in middle-aged mice. An experimental compound called D30, given during the sleep loss, partly protected them. Key Findings Three kinds of memory got worse: Rec…

TL;DR: In female mice, both too little and too much estrogen led to depression-like and anxious behavior, and both lowered one estrogen receptor in a mood-related brain area. Boosting that receptor eased the effects of stress. Key Findings U-shaped pattern in…

TL;DR: In mice, a new type of gene-silencing molecule lowered levels of alpha-synuclein, the protein that clumps in Parkinson’s. Mice given it kept more dopamine-making brain cells and did better on grip and balance tests than untreated mice with the same dise…

TL;DR: In female mice without ovaries, a model of menopause, the osteoporosis drug raloxifene and the hormone progesterone each protected brain dopamine from a toxin that mimics Parkinson’s. Giving both together worked no better than either alone. Key Findings…

TL;DR: Thin nerve fibers in the mouse brain are not smooth tubes but look like strings of tiny pearls, a shape set by the physics of their outer membrane. Changing that shape with drugs or heavy activity sped up or slowed down nerve signals by roughly 14% to 2…
