Scientists have succeeded in verifying a basic prediction of the quantum-mechanical behavior of resonant systems. They were able to carefully follow, one x-ray at a time, the decay of nuclei in a perfect crystal after excitation with a flash of x-rays. They observed a dramatic reduction of the time taken to emit the first x-ray as the number of x-rays increased.

A team of scientists from the United Kingdom has spotted the equivalent of smoke-rings in the Earth’s southern oceans which they think could ‘suck-up’ small fish and other creatures and carry them at high speed and for long distances. The Earth’s oceans are full of eddies, swirling motions some tens to hundreds of miles across, [...]

Floating solar fuels rig created for seawater electrolysis

#zrodlo

Chemical engineers have developed a novel photovoltaic-powered electrolysis device that can operate as a stand-alone platform that floats on open water. The floating PV-electrolyzer can be thought of as a 'solar fuels rig' that bears some resemblance to deep-sea oil rigs -- but it would produce hydrogen fuel from sunlight and water instead of extracting petroleum from beneath the sea floor.

Carbon capture could help coal plants reduce emissions if economic challenges can be overcome. Turning captured carbon into a useable product is one solution. Scientists have developed an efficient process for turning captured carbon dioxide into syngas that can be used to make fuels and chemicals.

Unusual thermal convection in a well-mixed fluid: Can a syrup separate when mixed?

Added: 16.12.2017 18:23 | 0 views | 0 comments

#zrodlo

Researchers have recently discovered unusual thermal convection in a uniform mixture of high and low viscosity liquids. They found that concentration fluctuations are enhanced by thermal convection when the two liquids have a large viscosity difference. Such mixtures are ubiquitously observed in nature, daily life, and manufacturing processes, e.g. mantle convection, syrup, polymer products. These results promise further insight into non-equilibrium phenomena in fluid mixtures with contrasting 'thickness.'

About one third of all medicine binds to the same type of receptor in the human body. An estimated three percent of the population have receptors of this type that are so genetically different that they are predisposed to altered, ineffective or adverse responses to medicine, a new study shows.

Despite decades long prevention and treatment efforts, cardiovascular (CV) disease continues to be the leading cause of death worldwide. Early detection of CV disease can allow for interventions to prevent heart attack and stroke, including smoking cessation, medications such as a statins, blood pressure control, weight management, exercise, and improved diet. A new study focuses on a novel risk factor for cardiovascular disease that rarely receives attention -- erectile dysfunction.

Heavy-petroleum fuels raising vanadium emissions

Added: 16.12.2017 18:23 | 0 views | 0 comments


Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke study finds. These emissions now exceed those from all natural sources combined. Growing evidence suggests exposure to vanadium-rich aerosols can impair respiratory functions and exacerbate conditions such as asthma or COPD.

A new study indicates an essential role for a maternally inherited gene in embryonic development. The study found that zebrafish that failed to inherit specific genetic instructions from mom developed fatal defects earlier in development, even if the fish could make their own version of the gene.
