Now You Can Feel Wind and Temperature While in Virtual Reality

Realistic visuals and audio are essential to shaping an immersive virtual reality (VR) experience. But these researchers from the National University of Singapore believe VR shouldn’t just cater to sight and sound. For the ultimate VR experience, other senses should come into play as well.

Last year, Nimesha Ranasinghe and his team demonstrated how electrodes can be used to add a sense of taste to VR. Their latest accessory, Ambiotherm, adds another element of realism to the experience: atmosphere.

(It responds to other “cooling agents,” too, like eucalyptol and icilin. Why, exactly, is unknown; menthol just happens to fit the cellular “lock.”)

Scientists Determine That Goldfish Can Feel Pain

It is a question that has puzzled scientists – and anglers – for generations, but now a team of researchers claims to have demonstrated that fish do feel pain.  

Whilst the creatures can clearly be seen to react to a jab or blow, experts have disagreed over whether the reaction indicates a sensation of pain, or is little more than a basic reflex.

Hand Transplant Patient Shows Signs Of Sensory Recovery

Hand Transplant Patient Shows Signs Of Sensory Recovery 

Activation of the left cerebral hemisphere during sensory stimulation of the transplanted right palm.  

Four months after a successful hand transplant — 35 years after amputation in an industrial accident at age 19 — a 54-year-old man’s emerging sense of touch is registered in the former “hand area” of the his brain, says a University of Oregon neuroscientist.
