TRPA1 "can transform the mechanical stimulus of a sound wave into an electrical signal recognizable by the brain. The protein forms an ion channel that opens in response to sound, causing electrical impulses that communicate the pitch, volume, and duration of a sound to the brain." https://lnkd.in/eCrD8Q8 View in LinkedIn

CURIOUS TEMPERATURE FLEXIBILITY. "TRPA1 is arguably the most fascinating TRP ion channel...as orthologs from different species demonstrate opposite temperature directionality." Some for heat, some for cold. https://lnkd.in/egjk4Ss View in LinkedIn

KEY TO SURVIVAL. "Transient receptor potential ankyrin 1 (TRPA1) is a polymodal ion channel sensitive to temperature and chemical stimuli. The importance of temperature and aversive chemical detection for survival has driven the evolutionary diversity of TRPA1 sensitivity." https://lnkd.in/e-WBvC9 View in LinkedIn

DIVERSITY "can be observed in the various roles of TRPA1 in different species, where it is proposed to act as a temperature-insensitive chemosensor, a heat transducer, a noxious cold transducer, or a detector of low-intensity heat for prey localization." https://lnkd.in/e-WBvC9 View in LinkedIn

ILLUSION DEVICE. "Just when you thought invisibility cloaks couldn’t get any weirder, researchers come up with this: a way to make one object look like any other." https://lnkd.in/exKwCuQ View in LinkedIn

STEP ONE. "The trick is to create a material in which the permittivity and permeability are complementary to the values in a nearby region of space containing the mouse we want to hide. “Complementary” means that the material cancels out the effect that the mouse has on a plane lightwave passing through." https://lnkd.in/exKwCuQ View in LinkedIn

STEP ONE. "So a plane wave would be bent by the mouse but then bent back into a plane as it passes through the complementary material, making the mouse disappear." https://lnkd.in/exKwCuQ View in LinkedIn

STEP TWO. "The second step is to then distort this plane wave in the way that an elephant would. This means creating transformational material that distorts a plane lightwave in the same way as an elephant. So anybody looking at this mouse would instead see an elephant." https://lnkd.in/exKwCuQ View in LinkedIn

PEEP HOLE. "The researchers have even found a mind-boggling application. Their idea is to create the illusion that a wall has a hole in it, and then use the hole to look through the wall. That’s not quite as bonkers as it sounds. The wall has to be pretty thin, and what the new device does is allow light to tunnel through the wall in a way that would not ordinarily be possible. Amazing, if it works." https://lnkd.in/exKwCuQ View in LinkedIn

SEEING THROUGH WALLS. "We propose to use transformation optics to generate a general illusion such that an arbitrary object appears to be like some other object of our choice." https://lnkd.in/eyBstN6 View in LinkedIn
