They found the evidence in medical papyri written in 1,500 BC, which is 1,000 years before the birth of the Greek physician Hypocrites, for whom today?s “Hippocratic Oath” was named.

We’ve written before about how dust blowing from China can change the weather in California. Now researchers have begun tracking a huge dust plume they believe they might affect clouds and weather across thousands of miles while playing a role in global warming.
Scientists are using high tech aircraft to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. The plumes are among the largest such events on Earth. The first mission will be launched in late April, when these weather patterns begin in Asia, and the study will continue for two months.
