How the Brain Functions Like a Social Network
A new model of how the brain works, using special glia cells to regulate the synapses, sorting information for learning purposes, could give rise to better computer algorithms.
What's the Latest Development?
Researchers have discovered a new essential function for half of the brain's cells. Called glia cells, scientists have known them to hold the brain's neurons together, protecting the cells that determine our thoughts and behavior. But now they believe glia cells do much more, actually regulating the synapses and sorting information for learning purposes. "Messages may originate with the neurons, which use the synapses as their delivery system, but the glia serve as an overall moderator, regulating which messages are sent on and when."
What's the Big Idea?
The glia model, developed at Tel Aviv University, provides science with a new view of how the brain functions and could be used in the treatment of neurodegenerative diseases like Alzheimer's and epilepsy. Researchers believe it will also aid computer engineers: "The model will provide a new tool to begin revising the theories of computational neuroscience and lead to more realistic brain-inspired algorithms and microchips, which are designed to mimic neuronal networks."

Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
The Canadian professor's old-school message is why many started listening to him.
- The simplicity of Peterson's message on suffering echoes Buddha and Rabbi Hillel.
- By bearing your suffering, you learn how to become a better person.
- Our suffering is often the result of our own actions, so learn to pinpoint the reasons behind it.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
