NEWS & EVENTS
In a step toward accelerating the production of new gene therapies, scientists report that they have developed remote-controlled, needle-like nanospears capable of piercing membrane walls and delivering DNA into selected cells. They say the new technique, which can ferry biological materials to cells with pinpoint accuracy, overcomes many of the existing barriers to effective gene modification. Read more at ACS Nano News.
A team led by engineers has opened a window into the cell by developing an optical tool that can read metabolism at subcellular resolution, without having to perturb cells with contrast agents, or destroy them to conduct assays. The researchers were able to use the method to identify specific metabolic signatures that could arise in diabetes, cancer, cardiovascular and neurodegenerative diseases. Read more at Science Daily.

Scientists peer inside mammalian cells, producing intricately detailed, 3-D images of the tiny structures within and tracking molecules' subtle movements. Read more at Stanford News.
Biomedical engineers are growing tracheas by coaxing cells to form three distinct tissue types after assembling them into a tube structure-without relying on scaffolding strategies currently being investigated by other groups. Read more from Case Western Reserve University Daily.
