Humans ignore motion and other cues in favor of a fictional stable world

Would you notice if all the objects around you simultaneously moved farther away? In a virtual-reality laboratory in Oxford, researchers have obtained the puzzling finding that humans can be "blind" to changes like this.

Using neural growth factor could allow researchers to mass produce stem cells for treatment of disease

Human embryonic stem cells (hES) offer great hope for the treatment of some devastating diseases, but finding a way to keep enough of these cells usable and healthy for transplantation in patients has been an ongoing problem.

Oddly shaped DNA can cause DNA breaks in mammalian cells

When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma, according to a study by researchers at The University of Texas M. D. Anderson Cancer Center.

Interleukin-15 encourages CD8+ T cells to proliferate and reduces their tolerance to tumor antigens

Certain types of white blood cells assist the body in destroying cancerous tumors. Among these are CD8+ T cells. The T is for thymus, the gland near the base of the throat that both raises up and weeds out blood cells involved in immune responses.

Scientists map brain area that may help find human brain stem cells

A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells.
