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.

A new generation of biosensors is transforming how we monitor health—by stretching with the body and sensing multiple signals in real time. Scientists have developed highly flexible biosensors that detect sweat pH, electrolyte levels, and electromyography (EMG) signals simultaneously. Their secret lies in a hybrid microstructure (HMS) that combines wave-like flexibility with microcrack stress dispersion, ensuring both durability and precision. Even under 60% strain or after 5000 stretching cycles, the sensors retain electrical stability. Coated with conductive polymers, the devices provide continuous and accurate feedback, making them ideal for next-level wearable technologies in personalized health monitoring.

Sepsis is a serious condition that arises due to an improper immune response of the body to an infection. It is characterized by simultaneous unbalanced hyperinflammation and immunosuppression. Though sepsis can have severe impact on patients of all ages, studies on elderly and octogenarian patients remain limited. Now, researchers have explored the immune profile in elderly and octogenarian patients with sepsis. The study reveals that continuous decrease in CD3⁺ T-cells is associated with higher mortality.
