A new study in Scientific Reports by Gliksman, Schwarz, and Naparstek examines how mathematical fluency declines with age across the four basic arithmetic operations — finding that division and subtraction show the largest age effects while addition is largely preserved, and that education and time since retirement are the strongest individual predictors of performance in older adults.

Mouse temperature is one of the easiest things to “handle” while quietly losing control. The main reason is simple: core temperature and surface (skin) temperature answer different questions. If you rely on only one, you get blind spots. This article covers the common monitoring approaches (continuous vs spot-check, core vs surface), shows where each fits (anesthesia, recovery, free-moving studies), and gives a few simple workflow recipes that improve stability without wrecking your throughput.

Cognitive load measures how much mental effort someone is using at a given time. Integrating it into Tobii eye tracking workflows reveals not just where people look, but how hard their brain is working — unlocking new insights in usability research, sports performance, and training.
