Sleep like a giraffe
Giraffenap is made to improve performance at work through short sleep. A Japanese company says that it will allow the user to be energetic in just 20 minutes. Inside the box are four points to help the body stand. That means he can rest his arms, legs and head in the box while still remaining standing, just like a giraffe.
“Seeing” the world in animals’ eyes
Do you want to know what the world is like in the eyes of animals? A team of scientists has made a special camera. It uses the technology of photography( 成像) to “see” lights at different lengths. This includes lights that we can’t see with our eyes, while animals can see them. This way, the camera can record videos as if through the eyes of animals.
Researchers in Australia have made a tool that can recreate a special glove with groups of 3D force sensors( 力传感器). If your friend wearing the glove picks up an object, it will physically press against your friend’s fingers. The force signals can be sent to your glove, making you experience the same sense of touch as your friend.
