Women with lower incomes have higher concentrations of the stress hormone cortisol in their hair, according to a new study from UCL.
The study also found that women whose income has gone up over the last 4 years have lower cortisol levels than those whose income went down, suggesting an association between long-term financial strain and stress hormones. (more…)
When NASA’s salt-seeking Aquarius instrument ascends to the heavens this June, the moon above its launch site at California’s Vandenberg Air Force Base won’t be in the seventh house, and Jupiter’s latest alignment with Mars will be weeks in the past, in contrast to the lyrics of the song from the popular Broadway musical “Hair.” Yet for the science team eagerly awaiting Aquarius’ ocean surface salinity data, the dawning of NASA’s “Age of Aquarius” promises revelations on how salinity is linked to Earth’s water cycle, ocean circulation and climate.
Salinity – the concentration of salt – on the ocean surface is a key missing puzzle piece in satellite studies of Earth that will improve our understanding of how the ocean and atmosphere are coupled and work in tandem to affect our climate. While satellites already measure sea surface temperature and winds, rainfall, water vapor, sea level, and ocean color, measurements of ocean surface salinity have, until quite recently, been limited to sparse data collected from ships, buoys and a small number of airborne science campaigns.
