It’s a rare and fascinating sight.

The strange purple slime has been spotted in the desert at the end of the year by British scientists, and it’s been known to be poisonous since it was first reported in Australia in 2008.

This is what it looks like.

Scientists at the University of Sheffield in the UK have been studying the slime since 2009 and have been observing it for years.

The slime has a unique structure.

It’s made up of two pieces of protein, and is composed of different kinds of cells, which can all act as “sponge” for the slime.

They have a unique set of properties, which make them very interesting to study and they are being used in laboratories around the world.

It’s also not the first time the slime has made headlines.

A few years ago, a British scientist spotted it in a UK garden, and later it was spotted in Germany.

Scientists say it has a similar chemical composition to the toxin that causes the fungus known as pyrethroid poisoning, but it has other characteristics.

It is a polymer.

“This is not a natural slime that comes out of the soil,” Professor Ian Hughes, who works at Sheffield’s School of Biological Sciences, told the BBC.

There are different types of organisms that can use this material as a sponge and there are other types of animals that can’t, so it’s something that could be a major problem.

He added: “The main concern is it could be contaminated with toxic materials that are used to make things like soap and detergents.”

The discovery has attracted attention from the US and the EU.

In March, the European Commission published a report calling for a ban on the production and use of synthetic pyrethroids, and an embargo on their export.

Meanwhile, scientists at the Australian National University are also working on new research that could make the slime more toxic.

Chemical analysis of the slime reveals it’s made of two distinct groups of bacteria, with two distinct forms of a peptide, called α-ketoglutarate.

At the moment, the peptide has only been studied in vitro, but if the scientists can confirm the substance’s toxicity in humans, it could open up new opportunities for research.
