How to use a Rubik’s cube in science?

A group of Chinese and American scientists gave a new life to the Rubik's cube by discovering how to diagnose different diseases with the help of the cube. 

The team of scientists led by Jonathan Sessler designed an unusual Rubik's cube, composed of hydrogel molecules blended with several chemical compounds. These compounds are used in medicine to diagnose the deviations in specific liquids - this way medics diagnose illnesses. 

On each side of the puzzle, there is a mixture of reagents, which makes this invention multipurpose. When compounds engage with skin and blood of a patient, they change the colour. An assessment of the patient's health condition is determined according to this test. 

It is not the only one innovative use of the Rubik's cube developed by scientists.  It was also suggested to create a device, which codes three-dimensional patterned information. This technology reminds standard QR-codes, but because of its 3-D system and significant color palette, it can keep a large amount of data.
