Wearable chemical sensor can measure the concentration of lactate in sweat

Do sweat it! Wearable microfluidic sensor to measure lactate concentration in real time

Lactate, a compound present in sweat, is an important biomarker to quantify during exercise. However, available wearable sensors can cause skin irritation, which calls for the use of different materials. In a recent study, scientists at Tokyo University of Science have developed a soft and nonirritating microfluidic sensor for the real-time measurement of lactate concentration in sweat. This wearable device will help monitor the state of the body during intense physical exercise or work.

Perceiving predators: Understanding how plants sense herbivore attack

This statement rightly holds true for plants that are eaten by herbivores insects or even mammals. Interestingly, these plants do not just silently allow themselves to be consumed and destroyed; in fact, they have evolved a defense system to warn them of predator attacks and potentially even ward them off. The defense systems arise as a result of inner and outer cellular signaling in the plants, as well as ecological cues. Plants have developed several ways of sensing damage; a lot of these involve the sensing of various elicitor molecules produced by either the predator or the plants themselves and initiation of an SOS
