Using integrated information theory, researchers at University of Tsukuba investigated heterogeneous criticality (a "flexible system" that can changeably respond to the environment) of a 10-fish school of Plecoglossus altivelis (Ayu). They discovered that the role sharing between supercriticality and subcriticality subgroups leads to a state of heterogeneous criticality for the entire group more easily than theoretical predictions.

Deciding when to stop driving can be challenging for older adults and their families. A study published today in the Journal of the American Geriatric Society shows that using a decision aid tool can be beneficial and help older adults when faced with this difficult decision.

In a randomized clinical trial with more than 300 participants, researchers looked at the long-term impact of providing Healthwise®, an online driving decision aid, to older adults to help reduce uncertainty towards their intent to continue or stop driving.

The researchers found overall, after two years of follow up, the group who used the online driving decision aid had significantly less personal uncertainty about which action to take (i.e., less decisional conflict) and less distress after making a decision (i.e., less decision regret) than the group who didn’t use the decision aid.

The Israel-Hezbollah conflict has deepened an education crisis in which children have lost up to 60% of schooling in six years, a new study shows. Even if the current ceasefire holds, the research indicates that there is a lack of forward planning for education recovery that could mean more children are left behind, and inequalities become further entrenched.
