Life expectancy success story (8/28/2011)

Increases in life expectancy, due to better quality of life and better health care, can be patchy, with the gap between rich and poor getting bigger as time goes on.

Researchers building new sensor that could stop falls by elderly, before they happen (8/23/2011)

Researchers building new sensor that could stop falls by elderly, before they happenResearches at Virginia Tech and the University of Virginia are creating a portable fall prediction monitoring system for detection of fall risks that can provide early diagnosis and treatment before a fall occurs to reduce injuries and death from falls. The device, which could look like a piece of jewelry, will measure potentially small declining increments in gait, posture and mobility of a patient, major indicators that can help point to a future fall. ...> Full Article

Weakness in aging tied to leaky muscles (8/4/2011)

There is a reason exercise becomes more difficult with age. A report in the August Cell Metabolism, a Cell Press publication, ties the weakness of aging to leaky calcium channels inside muscle cells.
