Summertime in northern Australia means monsoon storms -- and plenty of them. Tall, turbulent clouds associated with these storm systems form rapidly, release their energy in the form of rain, then tail away, leaving in their wake a surplus of moisture to feed the next system. This lifecycle--the formation of tropical convective clouds, their outflow into cirrus clouds, and eventual dissipation into water vapor--is a key component of tropical climate. However, the cloud properties and the extent of their impact on the environment are not well understood or well represented in computer models that are used to simulate climate change.
This week, a team of more than 25 international cloud climate scientists are conducting a three-day operations and planning simulation at Sandia National Laboratories in Livermore, California, to prepare for a complex experiment that will result in the most detailed data sets ever collected for tropical convection. Led by scientists from the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Program and the Australian Bureau of Meteorology (BOM), the Tropical Warm Pool International Cloud Experiment will take place in the region around Darwin, Australia, between January and February 2006.
Darwin is home to one of the ARM Program’s permanent research sites, equipped with a sophisticated array of remote sensing instruments to collect the continuous measurements needed to improve computer models that simulate clouds and climate. The upcoming experiment will include an unprecedented network of ground-based instrumentation, a ship operating off the coast near Darwin, and a fleet of low-, middle- and high-altitude aircraft for in-situ and remote-sensing measurements. Aircraft measurements taken during the experiment will be valuable for validating and improving existing ground-based measurements from the ARM site in Darwin, as well as satellite observations obtained by the National Aeronautics and Space Administration (NASA).

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...
