ScienceDaily: Oceanographers from MIT and Woods Hole Oceanographic Institution report that the northeast Pacific Ocean has absorbed an increasing amount of anthropogenic carbon dioxide over the last decade, at a rate that mirrors the increase of carbon dioxide emissions pumped into the atmosphere. The scientists, led by graduate student Sophie Chu, in MIT's Department of Earth, Atmospheric, and Planetary Sciences, found that most of the anthropogenic carbon (carbon arising from human activity) in the northeast...

Australian Broadcasting Corporation: A new documentary made with the help of NASA is a stark reminder of just how big an impact humans have had on the planet, according to a former astronaut who served as a space consultant on the project. Marsha Ivins was first selected into the NASA Astronaut Class of 1984 as a mission specialist and has since logged more than 1,300 hours in space. "[The idea] for this documentary was to show people not just life on board a space station ... but the footprint that we as human beings have put...

Toxic air pollution particles found in human brains

Guardian: Toxic nanoparticles from air pollution have been discovered in human brains in abundant quantities, a newly published study reveals. The detection of the particles, in brain tissue from 37 people, raises concerns because recent research has suggested links between these magnetite particles and Alzheimers disease, while air pollution has been shown to significantly increase the risk of the disease. However the new work remains a long way from proving the air pollution particles cause or exacerbate...
