Ocean sediments are a massive storehouse for the potent greenhouse gas methane. But methane only acts as a greenhouse gas if and when it reaches the atmosphere. Environmental scientists recently set out to discover whether or not this ancient-sourced methane, which is released due to warming ocean waters, survives the journey from the seafloor and reaches the atmosphere.
While some people have little anxiety about the Earth’s changing climate, others are experiencing high levels of stress, and even depression, based on their perception of the threat of global climate change, researchers found. Psychological responses to climate change seem to vary based on what type of concern people show for the environment, with those highly concerned about the planet’s animals and plants experiencing the most stress.
Women have many options for oral contraceptives that are safe, effective and reversible, but despite decades of research, men have none. Now, scientists report a rat study that shows they finally have a good lead for a male birth control pill. It’s based on ouabain, a plant extract that African warriors and hunters traditionally used as a heart-stopping poison on their arrows.
