When that strength wanes, the cloud tops drop and become less cold. That's because the higher you go in the troposphere, the colder it gets. NASA satellite infrared data has revealed that Tropical Storm Tony's cloud top temperatures are warming and the storm is weakening.
The AIRS instrument aboard NASA's Aqua satellite captured infrared imagery of Tropical Storm Tony on Oct. 24 at 12:17 p.m. EDT that showed the strongest thunderstorms (purple) east of the center of circulation but cloud top temperatures are warming. Those thunderstorms are reaching high into the troposphere where cloud top temperatures are as cold as -63 Fahrenheit (-52 Celsius).

The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured infrared imagery of Tropical Storm Tony on Oct. 24 at 12:17 p.m. EDT that showed the strongest thunderstorms east of the center of circulation, but cloud top temperatures are warming. Those thunderstorms are reaching high into the troposphere where cloud top temperatures are as cold as -63 Fahrenheit (-52 Celsius). The cloud pattern in Tony is also becoming less organized.
On Oct. 25, 2012 at 5 a.m. EDT Tropical Storm Tony had maximum sustained winds near 45 mph (75 kph). Tony was moving to the east-northeast near 23 mph (37 kph) and this general motion is expected to continue during the next couple of days. Tony's center is far from land, about 835 miles (1,345 km) southwest of the Azores Islands near 30.4 North latitude and 38.4 West longitude. Tropical storm force winds extend outward up to 105 miles (165 km) from the center.
According to the National Hurricane Center discussion of Tony, "the southwesterly winds have not substantially separated the surface circulation from the convective canopy, although a combination of the shear and cooler waters has weakened the deep convection."
The National Hurricane Center expects Tony to start losing tropical characteristics today and dissipate over the weekend of Oct. 27 and 28.Text credit: Rob Gutro

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...
