Children Born In Summer Are More Likely To Be Healthy Adults
According to the study, birth month affects birth weight and when the girl starts puberty, both of which have an impact on overall health of adults. The environment in the womb leads to differences in...
Can Rain Clean The Atmosphere?
As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is co...
Air Pollution Has Halved In The Middle East - Due To Armed Conflicts Since Arab Spring
Air pollution has decreased dramatically in parts of the Middle East in the past five years - partly due to armed conflicts since the Arab Spring. A new study suggests the improvement is the result of...
Inflatable ‘Space Elevator’ Invented By Scientists
Astronauts would ascend 12 miles into the stratosphere before taking off under new plans to build a space lift. It is an idea that every small child has had at some point. Instead of sending up rocket...
Variations In Atmospheric Oxygen Levels Shaped Earth’s Climate Through The Ages
Variations in the amount of oxygen in Earth's atmosphere significantly altered global climate throughout the planet's history. Efforts to reconstruct past climates must include this previously overloo...
Global Carbon Dioxide Levels Topped 400 PPM Throughout March In Unprecedented Milestone
Average global levels of carbon dioxide stayed above 400 parts per million, or ppm, through all of March 2015 -- the first time that has happened for an entire month since record keeping first began,
Air Pollution Linked To Brain Damage, Neurological Disorders
A new study confirms that long-term exposure to air pollution -- even at low levels -- can lead to brain damage that precedes other neurological disorders associated with old age. Investigator Elissa...
