Scientists create a floss pick that samples cortisol within saliva as a marker of stress and quantifies it with a built-in electrode. The system uses a polymer casting technology that can be adapted to capture a wide a range of markers, such as estrogen for tracking fertility, or glucose for tracking diabetes. Ease of use allows monitoring to be incorporated into many areas of treatment

Hyperspectral and RGB data fusion is becoming increasingly popular for Earth remote sensing applications. In this direction, a team of researchers from the Rochester Institute of Technology has developed a bimodal video imaging platform leveraging this fusion technique and examined its performance by utilizing data of dynamic near-shore waters. The proposed technology successfully predicts hyperspectral image frames using RGB video input, enabling the technology for next-generation applications.

Significantly surpassing their single-junction counterparts in power-conversion efficiency (PCE), two-terminal perovskite/silicon tandem solar cells have emerged as a game-changer in photovoltaics. However, due to the lack of effective optimisation of the device interface to maximise charge extraction efficiency and reduce energy loss, their widespread application has been limited. Researchers of The Hong Kong Polytechnic University (PolyU) have pioneered a novel bilayer interface passivation strategy to develop tandem solar cells that achieve a record-high PCE of 33.89%, representing a milestone in the development of solar technology.
