Touching. Not-touching. Sensing.
Through the crafty use of magnetic fields, scientists have developed the first electronic sensor that can simultaneously process both touchless and tactile stimuli. Prior attempts have so far failed to combine these functions on a single device due to overlapping signals of the various stimuli. As the sensor is readily applied to the human skin, […]
Touching the untouched.
Jellyfish are about 95% water, which makes them very difficult to study because most of the underwater tools available to marine biologists are clunky, heavy, and often shred jellyfish and other delicate creatures to pieces. A new ultra-soft gripper uses fettuccini-like ‘fingers’ inflated with water to gently grasp jellyfish and release them without harm, allowing […]
Making objects invisible is no longer the stuff of fantasy but a fast-evolving science. ‘Invisibility cloaks’ using metamaterials now exist, and are beginning to be used to improve the performance of satellite antennas and sensors. Many of the proposed metamaterials, however, only work at limited wavelength ranges such as microwave frequencies. Now, scientists report a […]
Listen. So that you touch…
Our eyes, ears and skin are responsible for different senses. Moreover, our brain assigns these senses to different regions: the visual cortex, auditory cortex and somatosensory cortex. However, it is clear that there are anatomical connections between these different cortices such that brain activation to one sense can influence brain activation to another. A study […]
Researchers found that gently stroking a baby seems to reduce activity in the infant brain associated with painful experiences. Their results suggest that lightly brushing an infant at a certain speed – of approximately 3 centimeters per second – could provide effective pain relief before clinically necessary medical procedures. (1) Touch. The most cryptic of […]
