Fizzy water may aid weight loss but can't replace healthy lifestyle

Fizzy water might aid weight loss by boosting blood glucose uptake and metabolism-the rate at which the body uses and converts energy-but the effects are so small, drinking it can't be relied on alone to shed the pounds, concludes a brief analysis published in the open access journal BMJ Nutrition Prevention & Health.

Brain scans reveal link between SSRI use and cognitive function

Researchers have found that SSRI (Selective Serotonin Reuptake Inhibitors) antidepressants have the potential to improve certain cognitive functions, such as verbal memory. They measured brain function in patients before and after taking the SSRI escitalopram and correlated this to a drop in the level of one of the serotonin receptors in the brain and to cognitive improvements during treatment.
