Bioengineers have developed programmable adeno-associated viruses that may be used to deliver peptide drugs. Read more at ScienceNewsline.
A new blood stabilization method significantly prolongs the lifespan of blood samples for microfluidic sorting and transcriptome profiling of rare circulating tumor cells, living cancer cells carried in the bloodstream. Read more at ScienceNewsline.
A new system designed to study how cavitation bubbles created by ultrasound therapy affect nearby cells shows that attaching microbeads to the cellular membrane could make techniques like sonogenetics or ultrasonic modulation safer and more effective. Read more from Duke University Pratt School of Engineering.
Scientists have designed bacteria to reflect sound waves like submarines. The technology could eventually allow doctors to image therapeutic bacteria in the body using ultrasound. Read more at Caltech News.
A study activated genes in human stem cells that initiate biomineralization, a key step in bone formation, according to a science team. Scientists engineered spider web silk combined with silica to activate cell membrane protein receptor integrin. The research will help scientists model intracellular pathways that govern bone formation and efforts to cure diseases such as osteoporosis and calcific aortic valve disease.

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.
