Feb 11, 2019 by News Staff

Made from specially engineered infrared-sensitive yarn, which responds to changes in the temperature and humidity of a person’s skin by dynamically collapsing or expanding the structure of its fibers, the newly-developed textile shows great potential in the development of clothing systems capable of autonomously adapting to demanding environments. This is the first textile to automatically change properties to trap or release heat depending on conditions....

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.
