Welcome to this week’s issue of At the Intersections. This edition focuses on the thresholds that govern biological, social, and organizational systems. We examine how shifts in material resources alter domestic routines, how continuous human effort masks instability in operational networks, and how microbial composition directs carbon storage across northern landscapes. Alongside these structural limits, we also look at computational modeling designed to detect ecological disruptions and identify indicators within human behavior before critical transitions occur.

Can daily movement tracking help predict suicide attempts in adolescents who self-harm?
|
|
|
Predicting suicide attempts among youth with a history of self-harm remains difficult. Researchers used surveys and activity tracker data from 1,321 United Kingdom adolescents with a history of self-harm to test predictive computer models.

How does bacterial diversity affect how northern peatlands store carbon?
|
|
|
Scientists poorly understand how bacterial diversity across vast northern peatlands affects the storage of carbon during global change. To investigate, researchers surveyed 171 moss-dominated peatlands and swapped peat samples between different regions in a large-scale experiment.

Can artificial intelligence help detect and manage harmful algae blooms?
|
|
|
Harmful algae blooms threaten water supplies, aquatic ecosystems, and human health, but existing monitoring tools face practical limitations. The researchers reviewed artificial intelligence applications and evaluated various computer learning methods used to detect and manage these blooms.
