All engine running,

running, absolutely genius.

Get this.

Welcome.

This is the show where we bring you science.

What that essentially means is

Discoveries,

the classes, research, technology, unbelievable.

Without further ado, this is the Naked Scientists.

Hello, welcome to the Naked Scientists Friday News Edition where each week we bring you right up to date with what is happening in the world of science, technology and medicine.

I'm Chris Smith.

On the way, how bacteria could be supercharging cancer cells, the ghost fishing nets laying waste to our oceans and could capturing carbon

underground hold the key to our net zero ambitions. The Naked Scientist

podcast is powered by UKfast.coDOT UK. Cancer occurs when DNA is damaged in such a way that cells begin to disregard the normal controls that regulate their behavior.

But in recent years, scientists have discovered that tumor cells may have accomplices that make them more malignant and possibly even

resistant to chemotherapy drugs. These accomplices are bacteria including ones

that are normally carried in the healthy human mouth.

They've been spotted in a large range of cancers, but it wasn't clear whether they were just

there because cancer cells are abnormal and have grabbed some of these harmless bacteria bacteria or whether the microbes are actively

contributing to the disease process. Now Scott Verbridge at Virginia Tech has

been able to show that when these bacteria are present, tumor cells behave differently. They grow and move

more actively. And not only that, but they can also alter the behavior of adjacent cancer cells
