The pixels in phone screens and other OLED displays appear to provide a uniform glow, but a team of University of Michigan Engineering researchers has discovered the light actually originates from nanoscale hotspots, some of which flicker.
Superconducting materials could play a crucial role in the energy-efficient applications of the future. However, several technical challenges still stand in the way of their practical use. Now, researchers at Chalmers University of Technology in Sweden have developed a new material design that addresses a major obstacle in the field: enabling superconductivity to operate at higher temperatures while also withstanding strong magnetic fields. This breakthrough could pave the way for far more energy-efficient electronics and quantum technologies.
Researchers at the MDI Biological Laboratory have identified how zebrafish regenerate and reconnect new kidney filtration units after injury, revealing a coordinated cellular process that allows newly formed nephrons to integrate into the kidney’s existing tubule network. The study, published in the journal Development, shows that specialized cells at the connection site briefly adopt invasive behaviors—extending protrusions that initiate the physical link between new and old structures—while neighboring cells simultaneously divide and expand the growing tubule. The work also identifies intersecting signaling pathways, including canonical and non-canonical branches of Wnt signaling mediated by the receptor fzd9b, that orient the connection and regulate cell behavior. Understanding how zebrafish achieve this precise integration may help researchers overcome a major obstacle in regenerative medicine: enabling lab-grown tissues and organoids to connect into existing organs and become fully functional.
With a new grant from the USDA’s National Institute of Food and Agriculture, a team of researchers led by Case Western Reserve University is developing advanced nanocomposite materials for sustainable food-packaging designed to help food stay fresh longer while reducing the environmental impact.
The Case Western Reserve-led research will focus on developing environmentally friendly packaging materials from renewable biological resources, including plant-based materials, such as corn, wood and agricultural residues.
The team will design biodegradable films that incorporate natural melanin-based nanoparticles. That material will help protect food from microbes, ultraviolet light and oxidation while maintaining mechanical strength, transparency and effective barrier performance.
