Polish scientists develop ‘nanoflowers’ for targeted antibiotic delivery in bone infections
Polish researchers have developed microscopic “nanoflowers” that allow antibiotics to be delivered directly to infected bones, enabling drugs to act faster, more effectively, and with reduced toxicity. The technology could be a breakthrough in the treatment of osteomyelitis, a severe bone and bone marrow disease that can lead to bone necrosis and growth disorders in children.

AI model predicts atomic motion in molecular simulations, boosting speed nearly 100-fold
An international team of researchers has developed an artificial intelligence model that can predict the motion of atoms in molecular systems directly, dramatically speeding up simulations used in chemistry, physics, and materials science. The model, called MDtrajNet, bypasses the traditional step-by-step calculations of atomic positions, a process that can require millions of steps and substantial computing power.
