Walking 100 steps a minute achieves moderate intensity activityWashington, March 17: While moderate physical activity is known to be beneficial to health, researchers are now suggesting people to walk 150 minutes a week, which is equivalent to 30 minutes each day 5 times a week.

Researchers at the School of Exercise and Nutritional Sciences, San Diego State University, point out that pedometers widely used as a physical activity monitoring tool are unable to measure activity intensity.

They have determined that a rate of at least 100 steps per minute achieves moderate intensity activity.

Scientists uncover origin of consciousness in the brain

Washington, Mar 17: Scientists have uncovered where exactly lies the origin of consciousness in the brain.

While some neuroscientists have argued that consciousness may arise from a single "seat" in the brain, the new study has suggested that four specific, separate processes combine as a "signature" of conscious activity.

For the study, researchers analysed the neural activity of people who were presented with two different types of stimuli – one that could be perceived consciously, and the other that could not.

By using the above information, Dr. Gaillard of INSERM and colleagues showed that the four processes occurred only in the former, conscious perception task.
