On April 8th 2019, scientists at the University of Edinburgh announced in the journal PNAS, that they have discovered a new state of matter. They are calling the new state of matter, "the chain melted state." There are currently five states of mater, solid, liquid, gas, plasma, and condensate. In the new state, matter is both a liquid and a sold. To make the discovery, the research team used artificial intelligence to test potassium under extreme temperatures and atmospheric pressure.
The computer data revealed that between 20,000 and 40,000 times atmospheric pressure and at temperatures of between 400 and 800 degrees Kelvin (280 to 980 degrees Fahrenheit), some of the potassium molecules formed chains that dissolved into a liquid, while the rest remained in its crystal form. This, "chain melted state," gives rise to two separate lattices, a guess and a host. The host, which represents 80% of the structure stays solid, while the guess part which represents 20%, is weaker and there fore melts.
Andreas Hermann, who co wrote the study says that the new substance is like, "a sponge material that can soak up a liquid," but in this case it would be more like a sponge that soaks its self up.
