When NASA's Aqua satellite passed over Irina on March 5 at 2211 UTC (5:11 p.m. EST) it captured an infrared image of the storm's cloud top temperatures using the Atmospheric Infrared Sounder (AIRS) instrument. AIRS data showed that the coldest cloud top temperatures (colder than -63F/-52.7C) that included the bulk of the showers and strongest thunderstorms were on the southern side of the storm.

On March 6 at 1500 UTC (10 a.m. EST), Tropical Cyclone Irina had maximum sustained winds near 45 knots (~52 mph/83.3 kph). Irina's strongest winds occurred on March 1, when maximum sustained winds were near 55 knots (~63 mph/~102 kph).
Irina is now about 415 nautical miles (~478 miles/~769 km) southeast of Maputo, Mozambique. The center is near 30.3 South latitude and 39.4 East longitude. It is now moving to the east-northeast.
The forecasters at the Joint Typhoon Warning Center noted that Irina is now "slowly weakening within a marginal environment characterized by cool sea surface temperatures near 25 Celsius/77 Fahrenheit (a tropical cyclone needs temperatures of 22.6C/80F to maintain strength) and moderate, westerly vertical wind shear." Cool waters and moderate-to-strong wind shear are two factors that weaken tropical cyclones.
Forecasters today at the Joint Typhoon Warning Center are now thinking that those conditions may batter Irina into dissipation in the next day or two, and residents of South Africa and Mozambique are hoping that happens.

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.

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...
