Displays with more brilliant colors through a fundamental physical concept      (via sciencedaily.com) 

New research has shown that a strong coupling of light and material increases the colour brilliance of OLED displays. This increase is independent of the viewing angle and does not affect energy efficiency.

Activity deep in Earth affects the global magnetic field      (via sciencedaily.com) 

Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth's core, where temperatures exceed 5,000-degrees C. New research from geophysicists suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities -- or anomalies, as scientists call them -- of the Earth's magnetic field.

Breakthrough in the understanding of quantum turbulence      (via sciencedaily.com) 

Researchers have shown how energy disappears in quantum turbulence, paving the way for a better understanding of turbulence in scales ranging from the microscopic to the planetary. The team's findings demonstrate a new understanding of how wave-like motion transfers energy from macroscopic to microscopic length scales, and their results confirm a theoretical prediction about how the energy is dissipated at small scales. In the future, an improved understanding of turbulence beginning on the quantum level could allow for improved engineering in domains where the flow and behavior of fluids and gases like water and air is a key question. Understanding that in classical fluids will help scientists do things like improve the aerodynamics of vehicles, predict the weather with better accuracy, or control water flow in pipes. There is a huge number of potential real-world uses for understanding macroscopic turbulence.

'Terminator zones' on distant planets could harbor life      (via sciencedaily.com) 

In a new study, astronomers describe how extraterrestrial life has the potential to exist on distant exoplanets inside a special area called the 'terminator zone,' which is a ring on planets that have one side that always faces its star and one side that is always dark.

Perovskite solar cells from the slot die coater -- a step towards industrial production      (via sciencedaily.com) 

Solar cells made from metal halide perovskites achieve high efficiencies and their production from liquid inks requires only a small amount of energy. Scientists are investigating the production process. At the X-ray source BESSY II, the group has analyzed the optimal composition of precursor inks for the production of high-quality FAPbI3 perovskite thin films by slot-die coating. The solar cells produced with these inks were tested under real life conditions in the field for a year and scaled up to mini-module size.

Compressive stress shapes the symmetry of Arabidopsis root vascular tissue      (via sciencedaily.com) 

A cytokinin-mediated, proliferation-based mechanism is involved in the generation and maintenance of cell-type specific tissue boundaries during vascular development in Arabidopsis roots. Specifically, the HANABA-TARANU transcription factor forms a feed-forward loop to cytokinin signaling, which in turn regulates the position and frequency of cell proliferation of proto-vascular cells such that mechanical stress of the surrounding tissues guides growth in an apical-oriented manor, maintaining cell patterning throughout the tissue section.

Where the HI-Virus sleeps in the brain      (via sciencedaily.com) 

The human immunodeficiency virus HIV-1 is able to infect various tissues in humans. Once inside the cells, the virus integrates its genome into the cellular genome and establishes persistent infections. The role of the structure and organization of the host genome in HIV-1 infection is not well understood. Using a cell culture model based on brain immune microglia cells, an international research team has now defined the insertion patterns of HIV-1 in the genome of microglia cells.

Cyprus's copper deposits created one of the most important trade hubs in the Bronze Age      (via sciencedaily.com) 

The coveted metal copper and a sheltered location turned the Cypriot village of Hala Sultan Tekke into one of the most important trade hubs of the Late Bronze Age. Recent excavations confirm the importance of the Bronze Age city in the first period of international trade in the Mediterranean.

Cellular waste removal differs according to cell type      (via sciencedaily.com) 

'Miniature shredders' are at work in each cell, disassembling and recycling cell components that are defective or no longer required. The exact structure of these shredders differs from cell type to cell type, a study now shows. For example, cancer cells have a special variant that can supply them particularly effectively with building blocks for their energy metabolism.

Modelling superfast processes in organic solar cell material      (via sciencedaily.com) 

In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. Scientists have now calculated how this happens by combining molecular dynamics simulations with quantum calculations and have provided theoretical insights to interpret experimental data.

Rsearchers examine combined effects of two combustion technologies on the emission of coal-fired boilers      (via sciencedaily.com) 

There is currently a large dependence on coal for power generation. As coal-fired plants cause environmental and health hazards, technologies such as swirl flow and air staging have been proposed to mitigate the pollutants in their emissions. However, it is unclear how effective these technologies are in reducing the environmental costs of these plants. Now, researchers have provided insights on this front in a new study, delineating their efficacies with experiments and simulations.

Bigger flowers, greater rewards: Plants adapt to climate disruptions to lure pollinators      (via sciencedaily.com) 

There's been a well-documented shift toward earlier springtime flowering in many plants as the world warms. The trend alarms biologists because it has the potential to disrupt carefully choreographed interactions between plants and the creatures -- butterflies, bees, birds, bats and others -- that pollinate them.

Study describes the structural and functional effects of several mutations on the androgen receptor      (via sciencedaily.com) 

The androgen receptor is a key transcriptional factor for the proper sex development -- especially in males -- and the physiological balance of all the tissues that express this receptor. The androgen receptor is involved in several pathologies and syndromes, such as the spinal and bulbar muscular atrophy or androgen insensitivity syndrome, among others, for which there is no specific treatment. Regarded as the main initial and progression factor in prostate cancer -- the second most common malignant disease in men in industrialized countries -- this receptor has been, for decades, the main therapeutical target for the treatment against this disease.

Indigenous Ashaninka DNA helps geneticists write new chapters of pre-colonial history in South America      (via sciencedaily.com) 

Geneticists have written new chapters in the reconstruction of pre-colonial Americas history after using DNA from the indigenous Ashaninka people from Amazonian Peru. They have discovered previously unexpected levels of genetic variation in this group and uncovered a strong hint that these people were involved in a South-to-North migration that led to the transition from an archaic to ceramic culture in the Caribbean islands.
