Sitting in traffic can certainly be infuriating enough to raise your blood pressure. But new research shows that traffic can raise your blood pressure and put your heart at risk in a more direct way - by exposing you to the pollution in exhaust fumes...
...lessons we learned out of this experience. Often, it is highly likely that you will ask yourself: “Why did I volunteer when these people don’t want to find solutions to their own problems?” You will wonder why you exhaust yourself with seemingly ridiculous bureaucratic collisions. Be determined and have patience—you will reach the layers that appreciate your generosity. Then—and only then—will you see the beauty of the country you are volunteering in.

...Cassini helped advance that research when it endeavored to determine the composition of the exhaust in the most straightforward way possible: by flying through it and registering the thousands of high-speed pellets that collided with its skin. The speed and density of the pellets confirmed that they were ice. Analyzing the precise composition of that ice has taken years, but the results, published this week in the journal Nature, were worth the wait...
