The ease of collection, and the ability to use "allogenic" cells from other rats rather than having to harvest the animal's own cells and culture them, meant a treatment was available not weeks after a stroke, when the damage was done, but in this case minutes.

The system the researchers tested used a type of solar cell known as dye-sensitized solar cells, a lightweight and inexpensive type where the active layer is composed of titanium dioxide, rather than the silicon used in conventional solar cells.
Because her lab's working with cells and proteins rather than mosquitoes and people, she can quickly and cheaply screen massive numbers of chemicals, even hundreds of thousands.
Likening plaque deposits to "tombstones, " she says the field historically has been too focused on autopsy findings like plaques rather than on whatever is killing brain cells while people are still alive.
But Dr Snyder puts his stem cells to destructive, rather than creative, use.
The focus was on their exercise habits and eye health rather than being a scientific study of eye cells.
When it does, the introduction of stem cell medicines will have a profound effect on the practice of medicine, and we can expect cocktail conversations to revolve around the potential stem cells have for saving lives, rather than beginning them.
By building heating into the flash memory design, Macronix thinks that flash memory cells could last 100 M write cycles rather than the 10 thousand or so cycles possible today with MLC flash memory.
"It highlights the idea that electromagnetic radiation might act on cells by affecting the attractive forces between them rather than simply causing heat damage to tissue, " she said.
