Situated between the continental shelf of the eastern United States and the north wall of the Gulf Stream flowing eastward from Cape Hatteras, the Slope Sea is a transition region between the productively rich coastal waters and the productively static open ocean.
In the current SeaWiFS special issue of Deep Sea Research II, University of Rhode Island oceanographers Stephanie E. Schollaert, Thomas Rossby, and James Yoder describe their four-year, NASA-funded study of the Slope Sea along the Gulf Stream in order to understand the processes that control the yearly variability of surface concentrations of chlorophyll, the pigment found in plants and algae.
Annually, cold, fresh Labrador waters "spill" into the Slope Sea, influencing the path of the Gulf Stream, pushing it south in the spring. Since the advent of ocean color remote sensing in 1978 and particularly since the 1997 launch of the dedicated ocean color sensor SeaWiFS, the surface chlorophyll concentration of waters off the U.S. east coast have been found to be highest in the north (e.g., Gulf of Maine, Georges Bank, Labrador shelf) and during the winter when the Gulf Stream is farthest south and more Labrador water is present.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
