Study looks at brain and movement planning

When you first notice a door handle, your brain has already been hard at work. Your visual system first sees the handle, then it sends information to various parts of the brain, which go on to decipher out the details, such as color and the direction the handle is pointing. As the information about an object is sent further along the various brain pathways, more and more details are noticed-in that way, a simple door handle turns into a silver-plated-antique-style-door-handle-facing-right.

New understanding of ion channels in the body

A discovery by Canada-U.S. biophysicists will improve the understanding of ion channels, akin to little 'nano-machines' or 'nano-valves' in our body, which when they malfunction can cause genetic illnesses that attack muscles, the central nervous system and the heart.

Racial differences in self-rated health at similar levels of physical functioning

When asked by health care professionals about their health, older African-American adults consistently report poorer health than whites of the same age do - even if both groups are functioning extremely well, a new study finds.

MRI brain scans provide valuable diagnostic information about Alzheimer's

MRI scans that detect shrinkage in specific regions of the mid-brain attacked by Alzheimer's disease accurately diagnose the neurodegenerative disease, even before symptoms interfere with daily function, a study by the Florida Alzheimer's Disease Research Center (ADRC) in Miami and Tampa found.

Compound from olive-skin pomace protects against colon-cancer

Researchers from the University of Granada and the University of Barcelona have shown that treatment with maslinic acid, a triterpenoid compound isolated from olive-skin pomace, results in a significant inhibition of cell proliferation and causes apoptotic death in colon-cancer cells.
