Interference at a double slit made of two atoms
The investigation and exploitation of light-matter-interaction in optical resonators is one of the central research topics in the Quantum Dynamics Division of Professor Gerhard Rempe, Director at the Max Planck Institute of Quantum Optics in Garching. A couple of years ago, the team succeeded in creating single-photon emitters using single atoms stored in optical resonators. The stationary atoms can, for example, serve as nodes for the exchange of quantum information in a long-distance quantum network.

Why celestial bodies come in different sizes
Our solar system contains one massive object—the sun—and many smaller planets and asteroids. Now researchers from Duke University in Durham, N.C. have proposed a new explanation for the size diversity, which is found throughout the universe and is called hierarchy. The researchers report their finding in the Journal of Applied Physics, from AIP Publishing.

The first principle study of electronic and optical properties in rhombohedral BiAlO3
Perovskite has a rhombohedral structure (or hexagonal) with formula ABO3, while belonging to the space group of R3c (number #161). They are popular in applications of functional devices, exhibiting the superconducting, piezoelectric and ferroelectric properties. BiAlO3 was also employed in improving the structural and electrical properties of BNT-based ceramics, due to the large polarization in the Perovskite structure. Furthermore, such material has been added into the PbTiO3, PbZrO3 and BaTiO3-based ceramics to improve their electrical properties. Using first principle methods, electronic and optical properties in cubic and hexagonal have been explored.

Image: Eclipse season begins for NASA's SDO
The 2016 spring eclipse season of NASA's Solar Dynamics Observatory began Feb. 19, 2016. These seasons – a time when Earth blocks SDO's view of the sun for a period of time each day – last around three weeks and happen twice a year near the equinoxes. The eclipses are fairly short near the beginning and end of the season but ramp up to 72 minutes in the middle. Most spacecraft observing the sun from an orbit around Earth have to contend with such eclipses, but SDO's orbit is designed to minimize them as much as possible, as they block observations of the sun. The spring season will end on March 12, 2016.

Synthesis of faulty protein chains leads to the formation of toxic aggregates
Protein aggregates are deemed to be one reason for the death of nerve cells in disorders such as Alzheimer's or Huntington's disease. As researchers at the Max Planck Institute of Biochemistry report in the current issue of Nature, they have now decoded a new cellular mechanism for the development of aggregates. Missing stop signals in the production of proteins lead erroneously to long lysine chains at the end of the protein. This in turn blocks the ribosomes, the cell's protein factory. Healthy cells detect blocked ribosomes and rapidly destroy useless proteins. If the necessary quality control machinery does not function properly, defective proteins accumulate and form toxic aggregates.

Why do cells make invadopodia?
During development and immune system function in animals, specialized cells acquire the ability to invade other tissues. Such invasive behavior is important for neural crest cells that invade skin and provide pigmentation, for embryos that penetrate the uterine wall to establish the fetal-maternal connection, and for immune cells that invade tissues to reach sites of injury and infection. Cell invasive behavior is also acquired by cells in a number of diseases, including asthma, rheumatoid arthritis, and most notably in cancer, where tumor cell invasion results in lethality.

Nerve ultrasound allows the exact diagnosis and therapy of injuries to the nerves
Nerve ultrasound has rapidly developed into becoming a more precise and easily applied diagnosis tool. People suffering from injuries of peripheral nerves and require reconstructive plastic surgery often have a long history of woe and many operations behind them. Today, with nerve ultrasound, this time of woe can be extremely truncated, as the ultrasound-supported view into the neural pathways helps to take more precise and faster measures during diagnosis as well as therapy. With their research at the clinical divisions for neuro-radiology and muscular-skeletal radiology (Management of the nerve ultrasound research team: Gerd Bodner), MedUni Vienna has substantially participated in the speedy development of these new sonography methods.

DNA as a weapon of immune defense
Our innate immune system, made up mainly of phagocytes, protects our body by exterminating bacteria. To do this, it uses two mechanisms. The first kills foreign bodies within the phagocyte itself. The second kills them outside the cell. These two strategies were already known to researchers, but only in humans and other higher animals. Microbiologists from the University of Geneva (UNIGE), Switzerland, have just discovered that a social amoeba, a unicellular microorganism living in the soils of temperate forests, also uses both these mechanisms, and has done so for over a billion years. Since this amoeba possesses an innate defense system similar to that of humans, while being genetically modifiable, the researchers can therefore carry out experiments on it in order to understand and fight genetic diseases of the immune system. This discovery can be read in the journal Nature Communications.

Whole-exome sequencing: A rational approach for 'diagnostic odyssey' patients
A new clinical study from the Mayo Clinic Center for Individualized Medicine shows that whole-exome sequencing (WES) could serve as a viable diagnostic approach for identifying rare inherited diseases and providing a resolution for patients on a diagnostic odyssey. WES is a laboratory process that determines, all at once, the entire unique DNA sequence (i.e., the inherited genetic material) of an organism's genome. WES provides patients with rare genetic conditions who have been evaluated by multiple providers over, sometimes, years, without a diagnosis (i.e., a diagnostic odyssey) an opportunity to get answers.

Quantitative assessment of dynamic deformability and adhesion of red blood cells possible
A team of researchers from the Case Western Reserve University (CWRU) in Cleveland, OH have developed a versatile microfluidic platform integrated with a cell dimensioning algorithm for quantitative assessment of dynamic deformability and adhesion of RBCs in controlled microphysiological flow. Accurate measurement of RBC deformability and adhesion, which are the two key biophysical factors of vaso-occlusion in SCD, holds great potential as a marker for evaluation of disease progression, gaining insight into disease pathophysiology, and development of novel therapeutics. Although various approaches have been utilized for measurement of deformability and adhesion of RBCs, such as atomic force microscopy and optical tweezers, none of these methods could be conducted at physiological conditions using whole blood in a clinically relevant way. The developed microfluidic system can probe deformation characteristics of RBCs at the single ! cell level, as well as reflecting microvasculature adhesion response in whole SCD patient blood samples.
