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.

Researchers Seek Vaccine for ‘Traveler’s Diarrhea’
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.
Infectious Bacteria Hibernate to Evade Antibiotics
University of Copenhagen researchers have discovered a surprising tactic of pathogenic bacteria when being attacked by antibiotics: hibernation.
NASA Sees Eastern Pacific’s Newest Tropical Storm Organizing
NASA provided an infrared look at newly developed Tropical Storm Rosa in the Eastern Pacific and found the storm was getting better organized.
How Leaves Talk to Roots
New findings show that a micro RNA from the shoot keeps legume roots susceptible to symbiotic infection by downregulating a gene that would otherwise hinder root responses to symbiotic bacteria. These findings help us understand what it takes to make nitrogen-fixing symbiosis efficient, and what we need to do to exploit it agronomically.
Super Typhoon Trami’s Rainfall Examined By NASA/JAXA’s GPM Satellite
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.
