Have you got an actual way to test this though?

Or is this still test tube level?

And how much better do the animals do?

Or how much delivery do you get?

And do you get enough that were those tumour cells in a human, they would see enough drug to destroy meaningful numbers of them, so you would make a clinical difference to that outcome?

Is it relatively translatable?

Are these sorts of nanoparticles already used in other applications clinically so you could just make up packaged up doxarubicin like this and apply your technique to the operating theatre tomorrow?

That'll be outstanding if you can do that because the the prognosis for glioblastoma is pretty bleak, isn't it?

So let's hope they can translate that technique quickly into the clinic.

Tom Kisby there, that study just out in science translational medicine.

But first, in 1492, Columbus sailed the ocean blue, or so the rhyme goes.

But by opening up the Americas, historians speculate that that voyage also unleashed a plague that devastated the native populations of the continents.

Was smallpox brought by the European incomers that spread like wildfire through an infection naive population with no herd immunity and contribute to civilization collapse.

The history and the archaeology agree.

So it looks like a very plausible hypothesis, but there's nothing like detecting the infection for real to really give confidence to a claim.

And that is what a team at the University of Chile have now done.

Writing in the journal Science, they present an analysis of two Inca mummies, carbon dated to between fourteen hundred ninety two and sixteen thirty one, and bearing skin lesions consistent with smallpox infection.
