As the little structures grow, their constituents specialize into different types of brain cells, begin to form connections and emit brain waves. They could be useful models for development and neurological conditions.
As Hurricane Dorian approaches Florida, consider that feeding style means that aggressive tangle-web spider colonies produce more offspring after severe weather, while docile colonies do better in calm conditions.

People who spent at least two hours outside—either all at once or totaled over several shorter visits—were more likely to report good health and psychological well-being. Jason G. Goldman reports.
A few brief reports about international science and technology from Canada to Kenya, including one about how humans thousands of years ago in what is now Argentina butchered and presumably ate giant ground sloths.
At the third Scientific American “Science on the Hill” event, “Solving the Plastic Waste Problem”, one of the issues discussed by experts on Capitol Hill was biodegradability.
In his memoirs, the womanizing writer Giacomo Casanova described suffering several bouts of gonorrhea—but researchers found no trace of the microbe on his handwritten journals. Karen Hopkin reports.
