New way to fight mosquitoes.
Researchers have grounded more about how mosquitoes discover hide odor, and they say their findings could front to better repellants and traps. Mosquitoes are attracted to our derma odor and to the carbon dioxide we exhale. Previous scrutiny found that mosquitoes have special neurons that franchise them to detect carbon dioxide hgher club. Until now, however, scientists had not pinpointed the neurons that mosquitoes use to learn of coat odor.
The new lucubrate found that the neurons used to detect carbon dioxide are also worn to identify skin odor. This means it should be easier to note ways to block mosquitoes' facility to zero in on people, according to the study's authors full report. The findings appeared in the Dec 5, 2013 edition of the diary Cell.

Transplantation Of Pig Pancreatic Cells To Help Cure Type 1 Diabetes
Transplantation Of Pig Pancreatic Cells To Help Cure Type 1 Diabetes.
Pancreatic cells from pigs that have been encapsulated have been successfully transplanted into humans without triggering an unaffected practice eat on the unusual cells. What's more, scientists report, the transplanted pig pancreas cells despatch begin to put out insulin in reply to euphoric blood sugar levels in the blood, improving blood sugar check in some, and even freeing two bodies from insulin injections utterly for at least a minuscule time view homepage. "This is a very radical and new mode of treating diabetes," said Dr Paul Tan, CEO of Living Cell Technologies of New Zealand.
So "Instead of giving persons with epitome 1 diabetes insulin injections, we hand over it in the cells that initiate insulin that were put into capsules". The public limited company said it is slated to present the findings in June at the American Diabetes Association annual engagement in Orlando, Fla. The cells that offer insulin are called beta cells and they are contained in islet cells found in the pancreas citation. However, there's a scarcity of at one's fingertips child islet cells.
For this reason, Tan and his colleagues in use islet cells from pigs, which formality as human being islet cells do. "These cells are about the measurement of a pinhead, and we place them into a tiny ball of gel more information. This keeps them concealed from the invulnerable system cells and protects them from an immune organization attack," said Tan, adding that folk receiving these transplants won't need immune-suppressing drugs, which is a prosaic barrier to receiving an islet room transplant.
The encapsulated cells are called Diabecell. Using a minimally invasive laparoscopic procedure, the covered cells are placed into the abdomen. After several weeks, blood vessels will spread to keep going the islet cells, and the cells begin producing insulin.
