A new NASA-led study helps answer decades-old questions about the role of smoke and human-caused air pollution on clouds and rainfall. Looking specifically at deep convective clouds -- tall clouds like thunderclouds, formed by warm air rising -- the study shows that smoky air makes it harder for these clouds to grow. Pollution, on the other hand, energizes their growth, but only if the pollution isn't heavy. Extreme pollution is likely to shut down cloud growth.
It seems “hangry” isn’t just a made-up term.
University of Guelph researchers have revealed that the sudden drop in glucose we experience when we are hungry can impact our mood.
NASA provided an infrared look at newly developed Tropical Storm Rosa in the Eastern Pacific and found the storm was getting better organized.
More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice — ice that was fully attached to the seafloor. The ice sheets were as large as they could get and at the time, sea level was much lower because a lot of ice was sequestered on the continent. As the planet warmed, the ice sheets melted and contracted, and sea level began to rise. LSU Department of Geology & Geophysics Associate Professor Phil Bart and his students have discovered new information that illuminates how and when this global phenomenon occurred. Their research recently published in Nature’s Scientific Reports may change today’s sea level rise predictions as Earth and its icy continent continues to warm.
The Global Precipitation Measurement mission or GPM core observatory satellite probed super typhoon Trami when it traveled above the northwestern Pacific Ocean and provided an analysis of heavy rainfall and cloud top heights.
Every year, millions of people have vacations and business trips ruined when they succumb to “traveler’s diarrhea” during their journeys. A major cause of traveler’s diarrhea is bacteria called Enterotoxigenic E. coli, or ETEC. A joint effort between the University of Georgia and the University of Texas at Austin has discovered how ETEC works to cause disease. They are using this information in an effort to develop a preventive vaccine for travelers.
