Prostate-targeted, engineered nanoparticles made of amorphous silica are effective in killing prostate tumors directly while enhancing anti-tumor immunity, according to a preclinical study led by investigators at Weill Cornell Medicine and the Cornell Duffield College of Engineering. The particles, derived from silicon dioxide, a common component of healthy foods or fossilized sedimentary structures from single-celled organisms, induced several complete remissions of aggressive tumors in mouse models, supporting the further investigation of their use in clinical trials.

A tiny new chip could give cameras and sensing systems a far sharper view of the world, helping them detect subtle differences in materials and environments that standard colour imaging systems cannot see.

Advances in structural biology have allowed scientists to determine molecular structures with atomic‑level detail, sometimes yielding static snapshots that do not reflect the dynamism of proteins. However, these motions are often crucial for biological function. Researchers from the Institute of Science and Technology Austria (ISTA) together with international collaborators have now combined several methods to shed light on how proteins ‘breathe’ and how some experimental techniques freeze their motion. The findings—which could boost protein design approaches and improve AI-based structural prediction tools—were published in Nature Chemistry.
