Daily exercise may cut heart attack risk even in polluted areas: Study

Researchers in Denmark, Germany and Spain evaluated outdoor physical activity levels (sports, cycling, walking and gardening) and nitrogen dioxide (NO2 pollutant generated by traffic) exposure in 51,868 adults, aged 50-65. Over a 17.7-year period, there were 2,936 first heart attacks and 324 recurrent heart attacks. Higher levels of pollution were associated with more heart attacks, however, the risk was lower among those who were physically active, the researchers found. Moderate […]

New technique allows scientists to see how brain cells 'talk'

In a new technique, scientists have developed a way to see brain cells talk – to actually see neurons communicate in bright, vivid colour. The new lab technique is set to provide long-needed answers about the brain and neurological diseases such as Alzheimer’s disease, schizophrenia and depression. Those answers will facilitate new and vastly improved treatments for conditions that have largely resisted scientists’ efforts to understand them. Researcher J. Julius […]
