Filling the Gap: High-latitude Volcanic Eruptions Also Have Global Impact
Volcanic eruptions always seize the attention of climate scientists, because the sulfate aerosols formed in the volcanic plumes may stay months to years in the stratosphere—the second layer of the Earth’s atmosphere—resulting in the increase of radiation reflection from the Sun back into space, and therefore cooling the Earth's lower atmosphere or troposphere in a long time period. It is traditionally believed that because of atmospheric circulation patterns, eruptions in the tropics could have an effect on the climate in both hemispheres while eruptions at mid or high latitudes only have impact over the hemisphere where they erupt.

The Hydroponic, Robotic Future of Farming in Greenhouses
When you think of automation, you probably think of the assembly line, a dramatic dance of robot arms with nary a human laborer in sight. But that’s child’s play. The grandest, most disruptive automation revolution has played out in agriculture. First with horses and plows, and eventually with burly combines—technologies that have made farming exponentially cheaper and more productive. Just consider that in 1790, farmers made up 90 percent of the US workforce. In 2012, it was 1.5 percent, yet America still eats.

Light Green Plants Save Nitrogen Without Sacrificing Photosynthetic Efficiency
The top leaves of crops absorb far more light than they can use, starving lower leaves of light. Scientists designed plants with light green leaves with hopes of allowing more light to penetrate the crop canopy and increase overall light use efficiency and yield. This strategy was tested in a recent modeling study that found leaves with reduced chlorophyll content do not actually improve canopy-level photosynthesis, but instead, conserve a significant amount of nitrogen that the plant might be able to reinvest to improve light use efficiency and increase yield.

Study looks at why ring-tailed lemurs raise a stink when they flirt with potential mates
A University of Toronto study finds that a unique ritual performed by male ring-tailed lemurs may come at a significant physical cost, but it likely helps their chances in securing a mate.Ring-tailed lemurs are Strepsirrhines, a sub-order of primates who share a common ancestor with humans. They are very social animals, living in large groups with females dominating the group. Like other lemurs, they huddle in large groups in order to keep warm and maintain social bonds, with lower ranking males often excluded.

A new way to store thermal energy
In large parts of the developing world, people have abundant heat from the sun during the day, but most cooking takes place later in the evening when the sun is down, using fuel — such as wood, brush or dung — that is collected with significant time and effort.
