Artificial brains may need sleep too

AI network simulations become unstable following continuous periods of unsupervised learning. When the networks were exposed to states that are analogous to human brain waves during sleep, the stability was restored.

COVID-19: Aerosolized particles carrying virus stay in the air longer than previously thought

New model reveals the aerosolized particles carrying the coronavirus can remain in the air longer than was previously suggested. Researchers modeled a scenario where an infected person coughs in a supermarket aisle and takes into consideration in-store ventilation systems. The model revealed the aerosol-cloud containing COVID-19 spreads outside the immediate vicinity of the coughing person and dilutes in the process, but the dilution occurs over several minutes.

Designing artificial brains can help us learn more about real ones

The lessons learned from developing artificial intelligence networks can help guide researchers down the path of understanding the brain as a computational system rather than a collection of cells. AI technology can help take exploring the human brain, behavior and neurodegenerative diseases to an entirely new level.
