Formerly tropical depression 23S, Robyn strengthened into a tropical storm this weekend. As of Monday, April 5, Robyn had maximum sustained winds near 60 knots (69 mph) gusting to 75 knots (86 mph). It was located about 370 nautical miles southwest of Cocos Islands, Australia, near 16.1 South and 92.0 East. Robyn was moving south-southeast at 7 mph (6 knots) and as it moves it is kicking up waves up to 18 feet high.
The Cocos Islands and Keeling Islands, also called the Territory of Cocos (Keeling) Islands, is an Australian territory. There are twenty-seven coral islands and two atolls in the group of islands.
NASA's Aqua satellite has been flying over Tropical Storm Robyn since it developed on Friday, April 2. The Atmospheric Infrared Sounder (AIRS) instrument captured infrared imagery of the storm that showed high, cold, thunderstorm cloud tops as cold as -63 Fahrenheit (-52 Celsius). That data helped forecasters see that Robyn had powerful rain-making thunderstorms. AIRS provided valuable infrared data on Robyn's cloud top temperatures, which are important because they tell forecasters how high thunderstorms are and the rule is: the higher the thunderstorm, the more powerful the tropical cyclone. AIRS imagery revealed this morning that deep convection (rapidly rising air that condenses and forms thunderstorms that power a tropical cyclone) has decreased. Meanwhile, the low-level center of circulation continues to remain well-organized and the strongest winds are in the southwestern quadrant of the storm.
The Joint Typhoon Warning Center noted that Robyn's movement southeastward is taking the tropical storm further into an area of higher vertical wind shear (which can weaken and tear the storm apart). As a result, Robyn is expected to weaken over the next three days while remaining at sea.

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...
