The Moderate Resolution Imaging Spectroradiometer aboard NASA's Terra satellite captured a true-color image of Hurricane Nadine in the Atlantic Ocean on Sept. 16 at 1345 UTC (9:45 a.m. EDT) while NASA's Global Hawk was flying around the storm.

Nadine strengthened to a hurricane on Friday, Sept. 14 at 11 p.m. EDT, and weakened back to a tropical storm on Sunday, Sept. 16 at 11 p.m. EDT. Nadine's highest wind speed as a hurricane was 80 mph (130 kmh).
NASA's Global Hawk landed back at the Wallops Flight Facility, Wallops Island, Va., in the morning hours on Sept. 15 after spending a full day gathering data from Hurricane Nadine.
"During the flight, Nadine strengthened from a tropical storm to a hurricane despite being hit by very strong westerly winds at upper levels and very dry air on its periphery," said Scott Braun, HS3 Mission Principal Investigator from NASA's Goddard Space Flight Center, Greenbelt, Md. Data from this flight will help scientists determine how a storm like Nadine can intensify even in the presence of seemingly adverse conditions. Nadine is currently a tropical storm.
"The Global Hawk, one of two associated with the HS3 mission, sought to determine how the structure of Nadine might change under the influence of strong vertical wind shear as it moved northward in the Atlantic, " Braun said. During its 22.5 hour flight around Nadine, the Global Hawk covered more than one million square kilometers (386,100 square miles) going back and forth over the storm in what's called a "lawnmower pattern."
The Global Hawk captured data using instruments aboard and also dropping sensors called sondes into the storm. The dropsonde system ejected the small sensors tied to parachutes that drift down through the storm measuring winds, temperature and humidity.
At 11 a.m. EDT) on Sept. 17, Tropical Storm Nadine had maximum sustained winds near 70 mph (100 kmh). It was located about 585 miles southwest of the Azores, near 32.9 North and 35.3 East. Nadine is moving to the northeast near 15 mph (24 kmh). The National Hurricane Center forecasts some weakening in the next day.

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....

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...
