Ultra-slow waves in the brain directly linked to consciousness   If you keep a close eye on an MRI scan of the brain, you'll see a wave pass through the entire brain like a heartbeat once every few seconds. This ultra-slow rhythm was recognized decades ago, but no one quite knew what to make of it. MRI data are inherently noisy, so most researchers simply ignored the ultra-slow waves.       Cancers may be detected at smaller size in breasts with implants, study reveals   Breast augmentation with implants does not interfere with the ability to detect later breast cancers--in fact, cancers may be detected at a smaller size in breasts with implants, according to a study in the April issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons.

New PET imaging agent could help guide treatments for people with neurological diseases   Researchers have developed a new imaging agent that could help guide and assess treatments for people with various neurological diseases, including Alzheimer's, Parkinson's, and multiple sclerosis.         UTA professor wins AHA grant to study biomechanical influences on ventricular development   A University of Texas at Arlington researcher is working to determine how blood flow and cardiac muscle contraction affects gene development that leads to ventricular chamber development in the heart.         Researchers compare mouse and human blood vessels under ischemic conditions   Peripheral obstructive arterial disease develops when blood vessels narrow due to arteriosclerosis and blood flow in the legs (or rarely the arms) becomes clogged. Intermittent claudication is when blood flow disturbances in a limb causes pain, numbness, or coldness during physical activity.

Scientists discover link between diminished dopamine-firing cells and ability to form new memories   A new link between diminished input from dopamine-firing cells deep inside the brain and the ability to form new memories could be crucial in detecting the earliest signs of Alzheimer's disease.       New technology using SLAM and AR enables doctors to perform more accurate biopsy   The University of Twente is currently developing a smartphone technology based on the usage of Simultaneous Localization And Mapping and Augmented Reality.
