Self-Propelling Micromotors Deliver Oral Vaccines

Wei et al developed a biomimetic self-propelling micromotor formulation for use as an oral antivirulence vaccine; the propulsion is provided by a magnesium-based core, and a biomimetic cell membrane coating is used to detain and neutralize a toxic antigenic payload; the resulting motor toxoids leverage their propulsion properties in order to more effectively elicit mucosal immune responses.

The unpleasantness of pain is an emotional phenomenon distinct from pain’s sensory qualities. To study how the brain processes pain-related emotions, Corder et al used neural calcium imaging in freely behaving mice. The team identified brain circuits that respond to pain and directly tested their causal role in motivational behaviors associated with acute and chronic pain.
