Associative learning: Primary school children outperform all other age groups

The ability to make the connection between an event and its consequences -- experts use the term associative learning -- is a crucial skill for adapting to the environment. It has a huge impact on our mental health. A study shows that children of primary school age demonstrate the highest learning performance in this area. The results pave the way for a fresh perspective on associative learning disorders, which are linked to the development of mental illness later in life.

Modifying graphene with plasma to produce better gas sensors

Gas sensors are essential for personal safety and environmental monitoring, but traditional sensors have limitations in sensitivity and energy efficiency. Now, researchers have developed an improved gas-sensing technology by treating graphene sheets with plasma under different conditions, creating structural and chemical defects that enhance ammonia detection. These functionalized graphene sheets exhibited superior sensing performance compared to pristine graphene, potentially paving the way for wearable gas detection devices for everyday use.

New insights into how gut cells respond to bacterial toxins

Researchers have found that specific gut cells, BEST4/CA7+ cells, regulate electrolyte and water balance in response to bacterial toxins that cause diarrhea. Their findings show that these cells greatly increase in number when exposed to the cytokine interferon- (IFN ), presenting a promising target for therapeutic strategies.
