| Powering pacemakers with heartbeat vibrations Posted: 01 Feb 2012 03:14 PM PST Aerospace engineers have developed a prototype device that could power a pacemaker using a source that is surprisingly close to the heart of the matter: vibrations in the chest cavity that are due mainly to heartbeats.  |
| Posted: 01 Feb 2012 11:17 AM PST About 18 million individuals undergo massage therapy annually in the U.S. Despite several reports that long-term massage therapy reduces chronic pain and improves range of motion in clinical trials, the biological effects of massage on skeletal tissue have remained unclear - until now.  |
| 'Life and activity monitor' provides portable, constant recording of vital signs Posted: 01 Feb 2012 11:00 AM PST Researchers have developed a type of wearable, non-invasive electronic device that can monitor vital signs such as heart rate and respiration at the same time it records a person's activity level, opening new opportunities for biomedical research, diagnostics and patient care.  |
| New technology shows molecules and cells in action Posted: 01 Feb 2012 10:53 AM PST A new affinity capture device provides a platform for viewing cancer cells and other macromolecules in dynamic, life-sustaining liquid environments.  |
| Societal control of sugar essential to ease public health burden, experts urge Posted: 01 Feb 2012 10:53 AM PST Sugar should be controlled like alcohol and tobacco to protect public health, according to a team of researchers, who maintain in a new report that sugar is fueling a global obesity pandemic, contributing to 35 million deaths annually worldwide from non-communicable diseases like diabetes, heart disease and cancer.  |
| Chaos in the cell's command center Posted: 01 Feb 2012 10:53 AM PST Researchers have determined the critical role one enzyme, lysine-specific demethylase 1 (LSD1), plays as mouse embryonic stem cells (ESCs) differentiate. This research may provide targets for developing drugs to push cells with dysfunctional gene expression programs back to a more normal, healthier state.  |
| Why the brain is more reluctant to function as we age Posted: 01 Feb 2012 07:51 AM PST New findings reveal a novel mechanism through which the brain may become more reluctant to function as we grow older.  |
| Encouraging results with stem cell transplant for brain injury Posted: 01 Feb 2012 07:45 AM PST Experiments in brain-injured rats show that stem cells injected via the carotid artery travel directly to the brain, where they greatly enhance functional recovery.  |
| Sleep apnea linked to silent strokes, small lesions in brain Posted: 01 Feb 2012 06:43 AM PST People with severe sleep apnea may have an increased risk of silent strokes and small lesions in the brain, according to a small study.  |
| Clot-busting drugs appear safe for treating 'wake-up' stroke patients Posted: 01 Feb 2012 06:43 AM PST Clot-busting drugs may be safe for patients who wake up experiencing stroke symptoms, according to preliminary research.  |
| Severe, rapid memory loss linked to future, fatal strokes Posted: 01 Feb 2012 06:43 AM PST Severe, rapid memory loss may be linked to -- and could predict -- a future deadly stroke, according to new research.  |
| Men more likely to have an accurate memory of unpleasant experiences Posted: 01 Feb 2012 06:27 AM PST Researchers reveal how pleasantness and emotional intensity affects memories. A woman's memory of an experience is less likely to be accurate than a man's if it was unpleasant and emotionally provocative, new research suggests.  |
