Walkable communities are healthier for both mom and baby: Study
Pregnant women that live in walkable communities—with more sidewalks, parks and walking paths—not only engage in more physical activity but are also more likely to experience favorable birth outcomes, according to research from the University of New Hampshire. The study found that expectant mothers living in walkable counties tend to engage in more walking and exercise and have fewer issues with premature births, low birth weight, gestational diabetes, and hypertension.

Blue-light filtering spectacles probably not so effective in preventing retinal damage
Spectacles that are marketed to filter out blue light probably make no difference to eye strain caused by computer use or to sleep quality, according to a review of 17 randomized controlled trials of the best available evidence so far.
