1. Active Astrocytes
This story from Quanta Magazine is about a shift in how neuroscientists think about astrocytes, the star-shaped support cells in the brain. The piece says these cells may do more than just help neurons, and instead may play a more active role in controlling brain signaling than many people once assumed.

2. Ultrasound BCI
This story from Wired is about a Chinese startup trying to build a brain-computer interface without implants, using noninvasive ultrasound instead of electrodes in the brain. The company, Gestala, is presented as part of China’s growing BCI industry, but the approach sounds closer to focused ultrasound brain stimulation than to a classic read-and-write interface.

3. EEG Golden Ratio
This story from the neuro community is about a preprint claiming that EEG spectral peaks line up in a golden-ratio lattice around a 7. 6 hertz fundamental.
