Scientists introduced a device that creates holograms using ultrasound & polystyrene ball

Researchers at the University of Sussex in the UK have introduced technology that can create holograms using ultrasound and a 2mm polystyrene ball. They can move and interact with the observer.


Scientists called the new technology "multimodal acoustic trap display" (multimodal acoustic trap display, or MATD). Images are created between two horizontal plates on which many tiny ultrasound speakers are mounted. They create an inaudible sound field in which there is a "pocket" of low pressure, where a polystyrene ball enters. By moving the "pocket", you can move the ball, forming an image. Colors are added to the image using the projector.
Through careful monitoring of the ultrasound field, scientists can add sound effects and music to animated images. Vibrations can be adjusted to receive sound waves in the entire range of human hearing and, for example, to imitate clear speech. In addition, you can interact with images and even feel them in your own hands.

The incredible survival story of the Dog maggie - Science Blog (October 2019)

Occasionally we hear stories of about animals who manage to survive obstacles and particularly serious injuries.

Science Hub Blog, October, 2019.

Life is beautiful - so smile!

As is the case with Maggie - a dog that gives us such a huge inspiration thanks to a sweet smile, blind eyes and one ear. 

Maggie's powerful and exciting story began when she was found in a box in Lebanon in harsh conditions while beaten and shot, which caused her to lose one of her ears and her eyesight. 

The person who found her posted on a social network asking for help to find the poor dog a warm home, and his publication was answered by a 25-year-old London girl.

She adopted the dog, Asking the Wild At Heart Foundation to help Maggie get the treatments she needed to recover, and now you can find out more about Maggie and see her pictures.
