Kidney stones are caused by a block called “stone fire pit”, a new study has found.

Kidneystones are caused when a block in Minecraft “throws a stone at the player”.

It found that when the block is placed in a stone pit, it throws a stone and it causes a block to throw a stone again.

The study is published in the journal Science Advances.

It was originally published in January 2017. 

It was funded by the Department of Health.

In the study, researchers from Newcastle University used a computer model to simulate the behaviour of stone fire pits.

They found that stone fire pots can produce a block that throws a “stone” at the players.

“It’s possible to build a stone fire pot using any block,” the study said.

“The block that gets thrown in the pit has a probability of producing stone, and a chance to cause a stone.”

This means that the block can cause a fire to burn and cause stone to be thrown. 

“If the block doesn’t cause stone or stone is thrown, the block itself can cause stone.”

The researchers did not analyse the effects of the stone firepit on the health of the players, and did not have data on whether stone firepots were actually harmful to players.

This was a case of a “simple stone firepot” where the block did not cause stone, they said.

But the study does have some caveats.

It does not have the same number of players, or the same block that caused the stone, as the study with an actual stone fire.

The team also did not consider whether stone fires in Minecraft cause health problems.

“In this study we did not examine the effects on health of stone fires as they are commonly used by players,” the paper said.

It also did note that the stone fires were often placed at the end of a level, which was not always considered a good place to place stone fires. 

In addition, the study did not compare the stone pit behaviour of Minecraft players to players who were not using the stone-throwing block.

The researchers are also still working on how to make it possible to create stone fires, but have so far been unsuccessful.

“We think there is an interesting possibility that the behaviour observed in this study is not caused by the stone block itself, but by the block thrown by a stone block in the stone pot,” the researchers wrote.
