A few years ago, MS researchers were focused on a new type of immune cell called the Th - 17 cell, which appeared to be a key player in driving the neuronal damage in MS. Because Th - 17 cells produce the cytokine IL - 17, researchers likewise thought this chemical was essential to the disease.

Most researchers assumed that this is because a few rogue cancer cells find ways to circumvent the drugs before the whole tumour has been killed off.

It's more efficient than previous devices, the researchers say, because its two cells absorb more light than single - layer solar devices, because it uses light from a wider portion of the solar spectrum, and because it incorporates a layer of novel materials between the two cells to reduce energy loss.

Collins said that because Hydra is such a simple animal and because it is able to regenerate after complete dissociation into individual cells, it offers researchers the opportunity to use similar techniques as the ones employed in their experiments to examine how an organism develops from an unstructured group of cells into a complex body plan.

The c - MYC pathway appeared to some researchers to be an unlikely therapeutic target for beta cell regeneration because past studies had found it to cause beta cell death when activated in high doses.

But when researchers injected Anas platyrhynchos ducklings at 4, 9, or 14 weeks old with red blood cells from sheep to simulate a parasitic infection, the birds — as adults — explored new items in their environment and approached small orange toys, a color they typically avoid because they seem to associate it with toxic food.

Because this approach jams the host cell machinery rather than directly attacking the bacteria, the chances of bacteria developing resistance could be very low, say the researchers.
