Environmental conditions can cause damaging stress to plants, posing challenges for home gardeners and farmers. Therefore, early detection — before leaves visibly discolor, wilt or wither — is crucial. Now, researchers reporting in ACS Sensors have created a wearable patch for plants that quickly senses stress and relays the information to a grower. The electrochemical sensor attaches directly to live plant leaves and monitors hydrogen peroxide, a key distress signal.

The invasive Pacific oyster have adapted to life in less salty seas and are reproducing off the coast of Skåne, although having been there for less than ten years. This discovery by researchers from the University of Gothenburg suggests that the oysters could colonise the western Baltic Sea in the future.

Dendritic structures that emerge during the growth of thin films are a major obstacle in large-area fabrication, a key step towards commercialization. However, current methods of studying dendrites involve crude visual inspection and subjective analysis. Moreover, growth optimization methods for controlling dendrite formation require extensive trial and error. Now, researchers have developed a new AI model that incorporates topology analysis and free energy to reveal the specific conditions and mechanisms that drive dendrite branching.

A research team led by SUTD has developed an acoustic method using empirical mode decomposition to detect stones hidden among coffee beans, preventing costly grinder damage in cafés and factories.
