**FILE PHOTO** In this Dec. 17, 2003 photo released by the U.S. Army Corps of Engineers, land loss in the marsh around Venice, La., a fishing and oil and natural gas town near the mouth of the Mississippi River, is shown. The Mississippi River delta plain is sinking an average of half an inch a year, raising doubts about whether the state can restore its rapidly disappearing coast by mimicking nature with freshwater river diversions, according to a geologist whose theories are rankling the scientific community. (AP Photo/U.S. Army Corps of Engineers)AP - A new report by scientists studying Louisiana's sinking coast says the land here is not just sinking, it's sliding ever so slowly into the Gulf of Mexico. The new findings may add a kink to plans being drawn up to build bigger and better levees to protect this historic city and Cajun bayou culture.

Dengue and other hemorrhagic fevers: Towards a first potential treatment

   IRD immuno-virologists and their research partners have determined the mechanisms involved in the occurrence of the vascular leakage triggered by the Dengue virus. Metalloproteinases are responsible for the passage of plasma across the blood-vessel walls. These original results, validated first by in vitro tests then in vivo on a mouse model, open up the first line of attack for treatment against hemorrhagic Dengue and new perspectives for others hemorrhagic fevers, such as Ebola.
