Researchers at Tufts University conducted an experiment using a 3D model of the human brain encased in a plastic shell. They simulated a concussion by striking the model, which led to devastating effects on a portion of the brain tissue. Notably, the brain tissue was found to be harboring a latent herpes simplex virus type 1 (HSV-1), which became active due to the trauma. The results showed significant inflammation, amyloid protein plaques, and neuron death, resembling characteristics of Alzheimer's disease

Google's AI-powered search results can be avoided by including expletives in search queries. For example, searching "How large is the student body of Yale University?" brings up an AI-generated summary, while phrasing it as "How large is the fucking student body at Yale University?" results in a standard list of links without the AI blurb. This method of disabling AI summaries is seen as more straightforward and satisfying than more complicated techniques, indicating a user preference for traditional search results over AI summaries,

The article discusses effective strategies for managing database migrations in Rails to maintain a consistent and organized database schema across different environments (development, staging, and production). Migrations are temporary tools designed for incremental changes and should not be relied upon once they have been executed; the schema file then becomes the definitive representation of the database state. In production and staging, migrations don't need to run repeatedly, and instead, developers can use the command `bin/rails db:schema:load` to sync the database.
