Exercise can slow onset of Alzheimer's memory loss: Scientists identify link

Exercise can slow onset of Alzheimer's memory loss: Scientists identify link: Keeping active can slow down the progression of memory loss in people with Alzheimer’s disease, a study has shown. Medical researchers have identified a stress hormone produced during moderate exercise that may protect the brain from memory changes related to the disease.

Ability to sit and rise from the floor is closely correlated with all-cause mortality risk

Ability to sit and rise from the floor is closely correlated with all-cause mortality risk: A simple screening test of musculo-skeletal fitness has proved remarkably predictive of all-cause mortality in a study of more than 2000 middle-aged and older men and women.

HPV in older women may be due to reactivation of virus, not new infection

HPV in older women may be due to reactivation of virus, not new infection: A new study suggests that human papillomavirus (HPV) infection in women at or after menopause may represent an infection acquired years ago, and that HPV infections may exist below limits of detection after one to two years, similar to other viruses, such as varicella zoster, which can cause shingles. The study highlights the need for additional research to better understand HPV infections and the role of HPV persistence and reactivation, particularly in women of the baby boomer generation.

Vegetable compound could become ingredient to treating leukemia

Vegetable compound could become ingredient to treating leukemia: A concentrated form of a compound called sulforaphane found in broccoli and other cruciferous vegetables has been shown to reduce the number of acute lymphoblastic leukemia cells in the lab setting, said researchers.

Brain damage triggered by mini-strokes detailed

Brain damage triggered by mini-strokes detailed: A new study details for the first time how "mini-strokes" cause prolonged periods of brain damage and result in cognitive impairment. These strokes, which are often imperceptible, are common in older adults and are believed to contribute to dementia.

Got food allergies? You can now test your meal on the spot using a cell phone

Got food allergies? You can now test your meal on the spot using a cell phone: Scientists have developed a lightweight device called the iTube, which attaches to a common cell phone to detect allergens in food samples. The iTube attachment uses the cell phone's built-in camera, along with an accompanying smart-phone application that runs a test with the same high level of sensitivity a laboratory would.

Unhealthy behaviors could slow progress in reducing heart disease, stroke

Unhealthy behaviors could slow progress in reducing heart disease, stroke: Poor eating and exercise habits could be the game-changer in the fight against heart disease and stroke deaths, according to new research.
