Astronomers discover new link between dark matter and clumpiness of the universe      (via sciencedaily.com)     Original source 

Researchers reveal a theoretical breakthrough that may explain both the nature of invisible dark matter and the large-scale structure of the universe known as the cosmic web. The result establishes a new link between these two longstanding problems in astronomy, opening new possibilities for understanding the cosmos. The research suggests that the 'clumpiness problem,' which centres on the unexpectedly even distribution of matter on large scales throughout the cosmos, may be a sign that dark matter is composed of hypothetical, ultra-light particles called axions. The implications of proving the existence of hard-to-detect axions extend beyond understanding dark matter and could address fundamental questions about the nature of the universe itself.

Earth was created much faster than we thought: This makes the chance of finding other habitable planets in the Universe more likely      (via sciencedaily.com)     Original source 

Over the past decades, researchers thought Earth was created over a period of more than 100 million years. However, a new study from suggests that the creation of Earth was much more rapid, and that water and other essential ingredients for life were delivered to Earth very early on.

Researchers describe the melting of gold nanoparticles in gold-bearing fluids in the Earth's crust      (via sciencedaily.com)     Original source 

Gold is a precious metal that has always fascinated humans. From Priam's Treasure to the legend of El Dorado, gold --regarded as the noblest of metals-- has been a symbol of splendour and wealth in many civilizations. Historically, gold deposits were known to form when metal was transported dissolved by hot aqueous solution flows --hydrothermal fluids-- until it accumulated in some areas in the Earth's upper crust. The recent discovery of gold nanoparticles in such mineral deposits has brought some doubts on the validity of the classical model.

Astronomers discover supernova explosion through rare 'cosmic magnifying glasses'      (via sciencedaily.com)     Original source 

An international team of scientists recently discovered an exceptionally rare gravitationally lensed supernova, which the team named 'SN Zwicky.' Located more than 4 billion light years away, the supernova was magnified nearly 25 times by a foreground galaxy acting as a lens. The discovery presents a unique opportunity for astronomers to learn more about the inner cores of galaxies, dark matter and the mechanics behind universe expansion.

As smart electronic devices become smaller and more powerful, they can generate a lot of heat, leading to slower processing times and sudden shutdowns. Now researchers use an electrospinning approach to produce a new nanocomposite film. In tests, the film dissipated heat four times more efficiently than similar materials, showing that it could one day be used to keep electronics cool.
