And the Hello and welcome to the naked scientists with Regre Jackson and Cat Arnie.

This week we're looking at symmetry and whether it holds the key to the theory of everything.

Plus the leading headlines in science this week including how whistled languages

could be unique when it comes to brain activity, a new color-changing material that could help identify head injuries and the latest from Perth Science Week.

First, when it comes to targeting cancer in the body, one of the biggest challenges is delivering drugs directly to tumors, killing cancer cells efficiently, while avoiding damage to healthy tissue that causes side effects.

Now a new study led by Anirin Kennerly at the University of Sheffield

reveals a novel way to guide immune cells loaded with cancer-killing viruses

into tumors using the power of an MRI or magnetic resonance

imaging scanner.

There are viruses that have been designed that can actively attack tumor cells.

One of the biggest problems is getting them to the tumor itself.

Obviously, bodies are going to fight viruses and if you just inject them, the body will naturally fight the virus away.

But what you can do is you can carry them inside a macrophage or a white blood cell

that your body is inherent to your body anyway and so we'll let pass

freely and it's kind of a Trojan horse therapy it's it's been known as

before the only problem with this is that if you just do this naturally about if

say I inject a few million white blood cells that have a cancer treatment in them

only 5% of them will ever reach a tumor site. And the initial ideas here were that

you would magnetize the white blood cells and then if you placed body the eye and within them would be attracted to the little external magnet and therefore they would stay in the

region of the tumor. The only problem with this technique is that it's only useful for kind of
