Hopkins Researchers Study Space Flight's Effects on Blood Vessels

Johns Hopkins Medicine

Are astronauts at risk of developing coronary artery disease from spending time in space, or can their blood vessels adapt to the change in gravity? To find out, Johns Hopkins researchers are preparing a cargo of special cells to board the shuttle Atlantis for a 10-day trip including a stop at space station Mir.

Basin traps air pollution in Mexico City -- International Study has implications for U.S. cities

Pacific Northwest National Laboratory

The first detailed measurements in Mexico City of pollutants such as peroxyacetal nitrate show concentrations similar to those that burned eyes and lungs in Los Angeles in the early 1970s, according to preliminary results of a field study conducted earlier this year. Peroxyacetal nitrate also is implicated in the production of ozone, another irritant that makes breathing difficult. The international study has implications for U.S. cities
