Researches at the Johns Hopkins University School of Medicine have developed a method for in vivo monitoring of transplanted-cell viability. The researchers used nanoscale pH sensors and magnetic resonance imaging (MRI) to track liver cells previously transplanted into mice. This new method is likely to be an important tool for improving cell replacement therapies for conditions such as liver… »

Although micro aerial vehicles (MAVs) could be very useful in search and rescue, exploration and environmental monitoring missions, due to their small size they still lack maneuverability. Johns Hopkins University (JHU) engineers are using high-speed video cameras to figure out how butterflies manage to fly with amazing grace and agility in order to improve maneuvering… »

Johns Hopkins researchers have developed a simple wound dressing that included a specially designed hydrogel – a water-based, three-dimensional framework of polymers – that promotes the formation of new blood vessels and skin, including hair follicles. It could lead to greatly improved healing for injured soldiers, home fire victims and other people with third-degree burns…. »
