Electron pairs (or pairs of holes) may survive the effort to kill superconductivity

Copper oxide layers of LBCO (the lanthanum barium layers would be in between). 3-D superconductivity occurs when the current in and between the copper oxide layers can flow freely while 2-D superconductivity exists when the current flows freely only within the layers (not perpendicular). The perpendicular orientations of stripe patterns from one layer to the next may be part of …

How big the holes in the Antarctic ice are, even though it's cold

This is an Inside Science story. (Inside Science) – By analyzing data from seal robots and sensors glued to seals, researchers can now understand the mysterious origins of giant holes that can open in Antarctic sea ice, according to a new study. A Polynya – a Russian word meaning "hole in the ice" – can form off the coast of …

The most detailed simulations of black holes solve many years of riddles

This image shows how the inner area of ​​the accretion disk (red) is aligned with the equatorial plane of the black hole. The outer disc is tilted away. The inner disc (where the black curve drops off) is horizontal, signaling the long-awaited Bardeen-Petterson alignment.

Black holes create Hawking radiation, possibly confirming the famous theory

Enlarge / Simulated view of a black hole in front of the Large Magellanic Cloud. Israeli physicists believe it confirmed one of the late Stephen Hawking's most famous predictions by creating the sonic equivalent of a black hole made of an exotic superfluid of ultra-cold atoms. Jeff Steinhauer and colleagues from the Israel Institute of Technology (Technion) have described these …

According to AMD, his chips are immune to new security holes

Continuing Bad News for Intel, Linux Specialist Phoronix performed tests demonstrating that the patches can significantly affect performance. Intel computers ran on average 16 percent slower with the newly installed updates and enabled hyper-threading features than 3 percent on AMD chips. To make matters worse, Apple and Google Intel users have advised to completely disable hyper-threading on Intel chips, if …

Are dark matter clumps breaking holes in the Milky Way? – RT World News

In an astrophysical model that explains a mysterious disorder in the galaxy, a "dense sphere" of dark matter may have been plowed through the Milky Way, which is a million times larger than the Sun. The theory of galactic hit-and-run "explains, according to Ana Bonaca, a Harvard-Smithsonian Center colleague, the jagged gap discovered in GD-1, the galaxy's longest stellar stream …

A "dense sphere of something" has blown up holes in the Milky Way

Bullet Holes Scientists say that some mysterious, gigantic, gigantic "bullet holes" pierced parts of the Milky Way. There are a number of holes in a long stream of stars called GD-1 Undiscovered thing has made its way, according to the research results submitted to the American Physical Society last month. Harvard-Smithson astrophysicist Ana Bonaca, the scientist who discovered the cosmic …
