A team of researchers has developed a simple three-minute brainwave test called Fastball EEG that can detect early signs of memory impairment linked to Alzheimers disease. Unlike traditional memory tests, it is passive a...
Chronic Stress Sends Immune Cells to Brain, Driving Depression
Neuroscience News - 2 Sep 2025 20:15
A new study shows that chronic stress causes immune cells called neutrophils to leave bone marrow in the skull and collect in the brains protective membranes, where they contribute to depressive symptoms. In mice, blocki...
Attention and Focus Abilities Peak Between Ages 27 and 36
Neuroscience News - 2 Sep 2025 20:03
Researchers analyzed 139 neuroimaging studies spanning ages 5 to 85 to map the brains activity in cognitive control. They found an inverted U-shaped lifespan trajectory, with brain activity rising through adolescence, pe...
1.8 million-year-old human jawbone discovered in Republic of Georgia - and it may be earliest evidence yet of Homo erectus

Freezing Brain Molecules Could Halt Deadly Cancer Spread
Neuroscience News - 2 Sep 2025 19:50
Scientists have identified a new way to stop glioblastoma - the deadliest form of brain cancer - from spreading by altering its environment rather than targeting the tumor directly. The team showed that cancer cells depe...
Alzheimers Linked to Epigenomic Breakdown, Not Just Plaques
Neuroscience News - 2 Sep 2025 19:34
A new large-scale study shows that Alzheimers disease is marked by the erosion of epigenomic control, where brain cells lose the ability to maintain stable gene expression. Using a multi-region atlas of 3.5 million cells...
