Scientists See Human-Like Brain Waves In Lab-Grown Mini-Brains
One way that scientists can non-invasively study the human brain is by growing “mini-brains,” clusters of brain cells each about the size of a pea, in the lab. In a fascinating progression of this line of research, a team this week reports that they observed human-like brainwaves from these organoids.

Mice Regain Their Sense Of Smell After New Stem Cell Therapy
Smells, like the tangy scent of the ocean or the acrid odor of smoke, are powerful cues that shape our memories and warn us of imminent threats. But for approximately 12 per cent of Americans over the age of 40, this crucial sense is significantly reduced or absent altogether. While scientists are still working to understand…

Project ‘DeepSqueak’ Aims To Decipher What Mice And Rats Are Really Chattering About
The image of a lab rat is an iconic symbol of scientific research, and for good reason: These rodents are remarkably good stand-ins for human subjects because of how closely their physiology and genetic make-up resemble ours. Because of this, mice and rats are used to study everything from cancer to diabetes to Alzheimer’s disease.
