No walk in the park: Factors that predict walking difficulty in elderly

Researchers have found that the likelihood of becoming disabled with age increases with the following factors: having a chronic condition or cognitive impairment; low physical activity; slower gross motor coordination; having poor lower-extremity function; and being hospitalized. Women are also more likely than men to become disabled in their later years.

Breast cancer spread triggered by a cleaver-wielding protein on cancer cell’s surface

Scientists have exposed a cell pathway that breast tumor cells use to destruct local tissue neighborhood. Cancer cells may use this pathway to free themselves from mammary epithelial tissue architecture, to spread to surrounding tissues. The cell pathway, the researchers found, is a biochemical chain of events leading to activation of a protein-cleaving enzyme on the surface of the tumor cells.

Traditional physical autopsies – not high-tech ‘virtopsies’ – still the gold standard for determining cause of death, experts claim

TV crime shows like Bones and CSI are quick to explain each death by showing highly detailed scans and video images of victims’ insides. Traditional autopsies, if shown at all, are at best in supporting roles to the high-tech equipment, and usually gloss over the sometimes physically grueling tasks of sawing through skin and bone.

Headphones linked to pedestrian deaths, injuries

Serious injuries to pedestrians listening to headphones have more than tripled in six years, according to new research. In many cases, the cars or trains are sounding horns that the pedestrians cannot hear, leading to fatalities in nearly three-quarters of cases.
