In the development of Parkinson’s disease, it may not be a good idea to turn the amp to 11. High-volume noise exposure produced motor deficits in a mouse model of early-stage Parkinson’s disease, and established a link between the auditory processing and movement areas of the brain, according to a study published November 4^th in the open-access journal PLOS Biology by Pei Zhang from the Huazhong University of Science and Technology in Wuhan, China, and colleagues.

LEDs are essential components in near-eye displays like virtual reality and augmented reality headsets and smart glasses, along with electronics like cameras and medical equipment. In Applied Physics Letters, researchers use AC power to drive an LED device instead of DC power, significantly reducing the complexity of fabricating nanoscale LED devices. In addition to simplifying the design, the researchers developed key improvements throughout the fabrication process and overall device performance.

Singlet fission (SF) offers a way to boost energy conversion in photosensitive materials by splitting energy from a single high-energy photon into two lower-energy excited states. In a recent study, researchers at Kyushu University developed a set of pressure-responsive SF-active molecules with flexible polar linkers. Their experiments revealed that adjusting pressure and changing the solvent can reversibly control SF rates, paving the way for advanced energy conversion materials and phototherapeutic applications.

A new material has been used to create a gel that can repair and regenerate tooth enamel, opening up new possibilities for effective and long-lasting preventive and restorative dental treatment.
