Using DNA origami as a virus-like scaffold, researchers designed an HIV-like particle that provokes a strong response from human immune cells grown in the lab. They are now testing this approach as a potential vaccine candidate in live animals, and adapting it to SARS-CoV-2, as well as other pathogens.

What factors affect how human touch perceives softness, like the feel of pressing your fingertip against a marshmallow, a piece of clay or a rubber ball? By exploring this question in detail, researchers discovered clever tricks to design materials that replicate different levels of perceived softness. The findings provide fundamental insights into designing tactile materials and haptic interfaces that can recreate realistic touch sensations.

The development of new bone can be a multistep process: first, stem cells differentiate into cartilage cells. Next, the cartilage cells become bone cells. But that's not all: the cells must experience some mechanical stresses during the transformation in order to transform efficiently from stem cells to bone cells.
