Welcome to At the Intersections. This week, we consider the signals our bodies and technologies send. From the electrical rhythms of a critically ill child’s brain to the chemical composition within the brains of people with psychosis, we look at how biological markers correspond with physical states and treatment outcomes. We also turn to the output of another system—artificial intelligence—and its effect on how multilingual learners are taught to write.

Do a critically ill child's sleep-wake cycles relate to their survival?
|
|
|
Critically ill children face multiple factors that disrupt their sleep, creating a need for a continuous monitoring tool. To characterize a potential method, researchers recorded EEG signals from mechanically ventilated children, transformed the data into amplitude-integrated electroencephalography (aEEG), and analyzed it for background patterns and sleep-wake cycling.

When AI can write, what does it mean to be a multilingual writer?
|
|
|
The emergence of generative artificial intelligence presents new considerations for teaching writing to multilingual learners, who may already experience linguistic discrimination. To address this, researchers conducted a qualitative study and interviewed 15 multilingual educators about their experiences teaching writing with this technology.

Does brain chemistry differ in people with psychosis who are nonresponsive to medication?
|
|
|
Not all people with psychosis improve with antipsychotic medication. To investigate this, researchers analyzed and synthesized data from multiple studies to compare brain chemicals in individuals who were responsive to treatment and those who were nonresponsive.
