Extra brain cells may be key to autism › News in Science (ABC Science) News in Science Wednesday, 9 November 2011 Julie SteenhuysenABC/Reuters Autism clue Children with autism appear to have too many cells in a key area of the brain needed for communication and emotional development, say US researchers.
They say their findings help explain why young children with autism often develop brains that are larger than normal. Dr Eric Courchesne, of the University of California San Diego Autism Center of Excellence, and colleagues, report their findings today in the Journal of the American Medical Association.

A unique approach to bone marrow transplantation pioneered in part by a Children's Hospital of Pittsburgh of UPMC physician has proven to be the only safe and effective cure for sickle cell disease, according to a new study.
Lakshmanan Krishnamurti, MD, a pediatric hematologist/oncologist at Children's Hospital, helped pioneer a form of bone marrow transplantation which relies on reduced-intensity conditioning (RIC). RIC regimens are less toxic to patients and therefore can be offered to patients with severe sickle cell disease because they eliminate life-threatening side effects generally associated with bone marrow transplantation. In a study published in the November issue of the journal Biology of Blood and Marrow Transplantation, Dr. Krishnamurti and colleagues report that six of seven sickle cell patients who received RIC bone marrow transplants in the last decade now have donor marrow and are free from symptoms of their sickle cell disease.

A step toward a saliva test for cancer. A new saliva test can measure the amount of potential carcinogens stuck to a person's DNA -- interfering with the action of genes involved in health and disease -- and could lead to a commercial test to help determine risks for cancer and other diseases, scientists reported here today during the 242nd National Meeting & Exposition of the American Chemical Society (ACS).

Dr. Forget the ice chest, this donor heart comes warm and still beating in a box. If you think about it, it’s strange that we keep to-be-transplanted human hearts in the same thing that we keep our Coronas in when we head to the beach. There must be a better way than sticking the heart on ice and flying it to its recipient. The heart can only be kept on ice for about six hours, so private jets, helicopters, and ambulances have to rush the heart to its recipient as fast as they can.

The capillaries are actually only one epithelial cell thick. They are so thin that blood cells can only pass through them in single file. The exchange of oxygen and carbon dioxide takes place through the thin capillary wall. The red blood cells inside the capillary release their oxygen which passes through the wall and into the surrounding tissue. The tissue releases its waste products, like carbon dioxide, which passes through the wall and into the red blood cells. YourGenome.org. General Pathology. 10 Vestigial Traits You Didn't Know You Had. Scientists unveil tools for rewriting the code of life. MIT and Harvard researchers have developed technologies that could be used to rewrite the genetic code of a living cell, allowing them to make large-scale edits to the cell’s genome.
Such technology could enable scientists to design cells that build proteins not found in nature, or engineer bacteria that are resistant to any type of viral infection. The technology, described in the July 15 issue of Science, can overwrite specific DNA sequences throughout the genome, similar to the find-and-replace function in word-processing programs.

Almost every person is born with fingerprints, and everyone's are unique. But people with a rare disease known as adermatoglyphia do not have fingerprints from birth.
Affecting only four known extended families worldwide, the condition is also called immigration-delay disease, since a lack of fingerprints makes it difficult for people to cross international borders.
