Conventional wearable sweat sensors utilize hydrophobic ion-selective membranes (ISMs) and require tight contact and adhesives to achieve signal stability. However, this can lead to user discomfort and skin-related diseases, necessitating the development of non-contact alternatives. In a new study, inspired by the self-cleaning behavior of rose petals, researchers developed novel ISM-based sweat sensors that feature enhanced signal stability and performance, avoid skin contact, and are reusable, making them practical for daily use.

Treating sepsis is a race against time. A new diagnostic method reduces the time to detect bacteria from days to hours, potentially helping hospitals save lives.

For decades zebrafish has eclipsed all other fish species in laboratories, but lately other, non-traditional model fish species are also in the spotlight. Amongst them is a once well-studied species of behavioral biology, the paradise fish. According to recent findings, its unique working memory and consistent exploratory strategy reveal behaviors previously thought to be characteristic mainly of mammals. Results published in Communications Biology by researchers from Eötvös Loránd University (ELTE) and the HUN-REN Institute of Experimental Medicine (HUN-REN IEM) suggest that the two species, taken together, can provide complementary insights into the workings of the brain.

A new collaborative study between Reichman University and the Technion reveals, for the first time, how living bacteria are able to survive inside dust particles transported through the atmosphere by desert storms originating in the Sahara Desert and Egypt, ultimately reaching Israel.
