Scientists have made an important step in understanding the organization of nerve cells embedded within the gut that control its function — a discovery that could give insight into the origin of common gastrointestinal diseases, including irritable bowel syndrome and chronic constipation.
Clarification of how human blood vessels are constructed is desperately needed to advance regenerative medicine. Researchers investigated the changes in gene functions that occur when stem cells become vascular cells. They found that the histone code, which alters the transcriptional state of the gene, changes over time as stem cells differentiate into blood vessels in response to a stimulus.
Going under the common name of Elfin mountain toad, a new amphibian is recognized as one of the smallest representative of its group. The new species was identified from the highland wet forests of Langbian Plateau, Southern Vietnam. The discoverers gave it this name that derives from German and Celtic folklore because of the resemblance they found between the tiny delicate amphibians and elves – small magic creatures. Furthermore, their habitat is known as elfin forests.
A new study opens a new perspective with regard to the development of dementia. The scientists blocked the breakdown of a certain fat molecule in the mouse brain. As a result the animals exhibited learning and memory problems. Also the quantity of Alzheimer-specific proteins in their brains increased significantly. The researchers now have a clue as to why the mice become dumb.
