A study released by the Minerals Management Service today examines the circulation in the Eastern Gulf of Mexico (GOM) and sheds new light on the behavior of the Loop Current (LC) and Loop Current Eddies (LCEs), the relation between the upper- and lower-layer currents, and the variability of water mass characteristics in deepwater.
When the LC and the LCE are present in the Gulf near oil and gas activities, operators may have to curtail or amend their operations due to the strength of the current or eddy.
"The observations from this study will help MMS and other scientists better understand the Loop Current and improve our forecasting of its behavior in the Gulf of Mexico," said Dr. Alexis Lugo-Fernandez, the MMS physical oceanographer responsible for the study. "This is important because oil and gas activities in the deepwater Gulf are affected by the presence of the Loop Current and the Loop Current Eddies."
Prepared under a cooperative agreement by Louisiana State University's Coastal Marine Institute, Observation of the Deepwater Manifestation of the Loop Current and Loop Current Rings in the Eastern Gulf of Mexico chronicled the deployment in the Eastern Gulf of a deepwater mooring cable measuring more than 11,800 feet for two years. The study supplements information gathered from a previous three year deployment.
The mooring data suggest the LC and LCEs that dominate upper-layer circulation in the Eastern GOM also influence the deeper currents in the Eastern GOM.
Dr. Lugo-Fernandez noted that a method to transmit significant energy in the form of heat to deep water in the GOM during the 2005 hurricane season was observed during this study. As sea levels rise near the center of tropical storms, the resulting higher pressure causes a small but measurable increase in temperature at all water depths. He explained that "Simply due to the large number of storm occurrences within the GOM, these findings represent an important process for transmitting energy to the deepwater."

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
