Washington, Oct 23 : Researchers at Penn State Hershey Cancer Institute have found that blocking signals from a specific protein that activates cells in the immune system could help kill cells that cause leukemia - a rare form of blood cancer.

The human immune system has a two-part strategy when dealing with infections. It generates antibodies that bind with bacteria and viruses to neutralize them.

For a short time, the immune system also produces large numbers of a type of white blood cell, cytotoxic T-cell that kills other infected cells.

Washington, Oct 23: No matter how fast we move or run, our eyes, head and body immediately adjust themselves according to our speed, and now scientists have uncovered the phenomenon underlying this unique ability, called vestibular-ocular reflex (VOR), in humans.

In their new study, researchers at the Salk Institute for Biological Studies explain how the vestibular-ocular reflex, which keeps us and the world around us stable, achieves the accuracy it is famous for.

The scientists said that signals from the vestibular system of the inner ear, which detects motion, are relayed in a linear fashion no matter how fast the neurons are firing, quite unlike other signals in the brain, whose transmission is frequency-dependent.
