Forty-four years ago, Nadrian Seeman published his groundbreaking ideas on using DNA as a structural material, expanding DNA's significance far beyond its role as a carrier of genetic information. Since then, the steadily growing field of DNA nanotechnology has seen numerous innovations. One was the DNA origami technique, which enables researchers to fold a single long strand of DNA into a desired 2D or 3D shape.

Oxford University researchers have captured the step-by-step assembly of individual virus-like particles, revealing how simple molecular interactions can reliably build these complex biological structures. The results were published today (September 16) in Nature.

Very small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline using a newly validated and improved technique: nanoscale infrared (IR) spectroscopy (s-SNOM) with ultrathin silicon-based membranes.

Glioblastoma is one of the most aggressive and treatment-resistant brain cancers known to medicine, carrying a median survival of just 12–15 months, even with the best available care.

An electrical fingerprint found on tiny particles in the blood may help detect signs of pancreatic cancer that are often overlooked, according to new research from Rice University. The researchers developed a device that separates these particles based on their electrical charge, making cancer-associated signals more visible.

Researchers, including those from the University of Tokyo, found a way to optimize how cells bind to small packages they release called extracellular vesicles. By coating the vesicles with metal ions, they made cells and their corresponding vesicles stick together more strongly than they would naturally. This reduced the time needed for cells to capture their own vesicles, even in mixtures containing billions of other vesicles.

The immune system, the body's defense network against infections and injuries, can sometimes become too active. In these cases, it can produce too many immune mediators, fragments of genetic material or proteins that regulate immune responses.
