Ultrafast probing reveals intricate dynamics of quantum coherence

Ultrafast, multidimensional spectroscopy unlocks macroscopic-scale effects of quantum electronic correlations. Researchers found that low-energy and high energy states are correlated in a layered, superconducting material. Exciting the material with an ultrafast beam of near-infrared light produces coherent excitations lasting a surprisingly 'long' time of around 500 femtoseconds, originating from a quantum superposition of excited states within the crystal. from Latest Science News -- ScienceDaily https://ift.tt/2TcnLaM

Efforts to develop heterogeneous catalysts that appeal to the fine chemical industry have been limited by underwhelming results. Although some approaches have shown promising catalytic activity, "heterogenization" itself is not enough.

Design of the W7-X fusion device enables it to overcome obstacles, scientists find

A key hurdle facing fusion devices called stellarators—twisty facilities that seek to harness on Earth the fusion reactions that power the sun and stars—has been their limited ability to maintain the heat and performance of the plasma that fuels those reactions. Now collaborative research by scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and the Max Planck Institute for Plasma Physics in Greifswald, Germany, have found that the Wendelstein 7-X (W7-X) facility in Greifswald, the largest and most advanced stellarator ever built, has demonstrated a key step in overcoming this problem. from Phys.org - latest science and technology news stories https://ift.tt/2HTqu2x

But in some cases, researchers find it difficult to reproduce the results of certain studies, and often their findings turn out to be different from the original ones—even when the same methods and procedures are used—thereby making the study unreliable. This discrepancy is called a "reproducibility crisis"—or the inability of scientific findings to be replicated by other researchers.

Himalayan wolf discovered to be a unique wolf adapted to harsh high altitude life

The Himalayan wolf is considered an ancient wolf as it evolved prior to the contemporary grey wolf which is found in large parts of North America and Eurasia. Very little is known about the Himalayan wolf, because science and conservation have overlooked these high-altitude wolves as just another grey wolf until recently. As a result, very little research had been conducted on this wolf and no conservation action has been in place, risking a silent population decline of this wolf. This research, published today in the Journal of Biogeography, reveals this wolf's evolutionary uniqueness based on many different genetic markers; including a genetic adaptation to cope with the high-altitude environment, which is an adaptation that is not found in any other wolf. The Himalayan wolf is a top carnivore in the Asian high-altitudes, which hold some of the last intact large wilderness areas on our planet. The protection of the Himalayan wolves is critical to preserve these ecosystems given t...

A submillimeter survey of protostars

The formation of stars involves the complex interactions of many phenomena, including gravitational collapse, magnetic fields, turbulence, stellar feedback, and cloud rotation. The balance between these effects varies significantly between sources, and astronomers have adopted a statistical approach to understand the typical, early-stage star formation sequence. The earliest stage is called the protostellar stage. For low-mass stars (those with masses about that of the sun) this stage is usually separated into two subclasses as the star grows by accreting material from a massive envelope whose size can extend between five hundred and ten thousand astronomical units (AU) in a process that can last roughly half a million years.
