New quadruple fusion imaging helps diagnose eye conditions and tumors
A quadruple fusion optical and ultrasound imaging system has been developed that allows diagnosis of eye conditions or tumors or to see the environment inside the body using a transparent ultrasound transducer.

We asked what you wanted to see in the photo gallery. Reader Robert McCarthy wondered what the section of campus that he remembers as the tundra looks like now. He recalled cold walks in the 1970s from his residence hall to class at Wells Hall. This photo, taken last week from an upper floor of Holden, shows the current tennis courts, Spartan Stadium, the football practice field, the new STEM building being constructed at the site of the old power plant and Wells Hall in the distance. We hope this brings back warm memories. Photo by Derrick L. Turner.
Researchers develop near-infrared light triggered drug delivery system
A new concept of on-demand drug delivery system has emerged in which the drugs are automatically released from in vivo medical devices simply by shining light on the skin.
A research team led by Professor Sei Kwang Hahn of the Department of Materials Science and Engineering and Professor Kilwon Cho of the Department of Chemical Engineering at POSTECH have together developed an on-demand drug delivery system (DDS) using an organic photovoltaic cell coated with upconversion nanoparticles. This newly developed DDS allows nanoparticles to convert skin-penetrating near-infrared (NIR) light into visible light so that drug release can be controlled in medical devices installed in the body. These research findings were published in

Light weight fiber reinforced composites have replaced metals in many applications from automobile parts to satellites and from windmill blades to sporting goods. Most of these composites are made using fibers and resins that are derived from petroleum. Since they tend to be non-degradable, non-recyclable and non-reusable, most of them end up in landfills at the end of their life. Green composites made from plant-based fibers and resins on the other hand are fully sustainable and compostable. Since the beginning of the research on green composites that started only 25-30 years ago, a significant progress has been made. Natural fiber reinforced green composites now can be found in many applications from automobile parts to housing and from furn
