Scientists have invented a major new advance in DNA nanotechnology. Dubbed 'single-stranded origami,' their new strategy uses one long, thin noodle-like strand of DNA, or its chemical cousin RNA, that can self-fold -- without even a single knot -- into the largest, most complex structures to date. The strands forming these structures can be made inside living cells, opening up the potential for nanomedicine. Read more form Arizona State University.
Much as a frame provides structural support for a house and the chassis provides strength and shape for a car, a team of engineers believes they have a way to create the structural framework for growing living tissue using an off-the-shelf 3-D printer. Read more at Penn State News.
Cancer imaging can be simplified by a photonic process utilizing molecules derived from horse chestnuts, research shows. Read more at Phys.Org.
Using light-emitting nanoparticles, scientists have invented a highly effective method to detect tiny tumors and track their spread, potentially leading to earlier cancer detection and more precise treatment. The technology could improve patient cure rates and survival times. Read more at Medical NewsToday.
Micro-grippers may be able to navigate unstructured environments and could help reduce risk during surgeries, according to a new study. Read more at Phys.Org.
Scientists have adapted DNA-PAINT technology to microscopes that are widespread among cell biology laboratories, called confocal microscopes, and that are used by researchers to image whole cells and thicker tissues at lower resolution. They have demonstrated that the method can visualize a variety of different molecules, including combinations of different proteins, RNAs and DNA throughout the entire depth of whole cells at super-resolution.

Engineers and nutritionists have created a swift solution for a challenging global health problem: a low-cost, rapid test to detect iron and vitamin A deficiencies at the point of care. Read more from Cornell University.
Engineers have developed a smartphone case and app that could make it easier for patients to record and track their blood glucose readings, whether they're at home or on the go. Read more at the UC San Diego News Center.
