If it can get down this small wow!
siRNA delivery into human T cells and primary cells with carbon-nanotube transporters
Quote:
A promising approach to gene therapy involves short DNA fragments (interfering RNA) that bind to specific genes and block their "translation" into the corresponding, disease-related protein.
A stumbling block has been the efficient and targeted delivery of RNA into the cells. Researchers led by Hongjie Dai at Stanford University have chosen to use carbon nanotubes as their "means of transport". This has allowed them to successfully introduce RNA fragments that "switch off" the genes for special HIV-specific receptors and co-receptors on the cells' surface into human T-cells and primary blood cells.

I wonder if I should buy some for the garden?
Could my plants then have DNA Swapping Parties then?

Might as well get all the off topics off my chest
On indigenous burning i am discovering many other native peoples used fire other than Australian Aborigines But Yourkshiremen?
I am a "Who-dun-it" fan and love quirky detectives. I am currently delighting in Nicholas Rhea's delightful D.I. Montague Pluke He is an expert on horse troughs and local folklore. (Yes I know only in an English/UK book could you get this)
In the first few pages of "Prize Murder' we came across a body in a burnt field.
Just before this we get a little history of Yorkshire Moors. Pluke is talking to his long suffering wife, Millicent.I hope you find this quirky bit of information as interesting as I did.
Quote:
"'A whole area of heather has been burnt away'
'It's a swidden, sometimes called a swizzen.' Pluke aired his knowledge.
'It's a result of controlled burning. It's done every year, often in march before the grouse start their nesting. The landowner burns off about a sixth of a given area of heather, then the following year it will be the turn of another sixth and so on, so that over a period of years, the entire mooreland is burnt.'
'Goodness! But why?'
'It destroys the old heather, clears and refreshes the ground and encourages new growth. New shoots of heather grow quickly and they're stronger and healthier than the old; the new shoots are needed to feed the grouse too, and in former times local people would remove the turf after the burning and use it for domestic fires.'
'So turf is not the same as peat? I know a lot of mooreland farms had peat fires,' said Millicent.
'That's right but they had turf fires too. turf burns more slowly and gives out a lot of heat with a very pleasant scent. The thick heather stems which survived the flames were collected for kindling to light home fires.Those stubby stalks were called cowls, they were collected in big bundles called boddins, the local way of saying burdens. Boddins o' cowls, as the local people called them.
The whole exercise of controlled burning was, and still is, a necessary, useful and very effective means of maintaining the moors.'"
