A study in Nature suggests that a critical flow system did not completely collapse under extreme conditions, sharpening the debate about transition thresholds today.
The quantum interference experiment as seen under an electron microscope. Using bilayer graphene, scientists controlled the trajectory of an anion in the material (in red). They made its wave go around an island containing a magnetic field and other anions (in green) and then brought it back together with the original wave to study its properties. The electrical gates (in dark gray) allow scientists to direct the anions along specific paths in the material and also determine the density of electrons in the island.

Weizmann Institute scientists identify quantum "memory particles" – a step towards a durable quantum computer

Weizmann Institute of Science scientists have found new evidence for the existence of a system of particles that "remembers" which quantum states it was in before, taking another step toward a fault-tolerant quantum computer.
Image caption: Princeton researchers have found that the prefrontal cortex of primates reuses modular thinking blocks to solve similar tasks. This gives biological brains a flexibility that artificial intelligence still lacks. The insight could help improve AI systems so that they retain old skills even as they learn new ones.

Researchers have found that the brain repeatedly relies on the same cognitive “building blocks” when performing different types of tasks. By reassembling these blocks in new ways, the brain can rapidly generate behaviors
After the Big Bang, an interstellar cloud of gas and dust composed of the elements silicon (gray), sulfur (yellow), and argon (purple) remained.

Giant star caught naked, revealing source of silicon and sulfur formation

An international team of scientists, led by Northwestern University and the Weizmann Institute of Science, has identified a new type of supernova that provides a rare glimpse into the depths of stars and reveals sites of production of heavy chemical elements.

Ancient DNA reveals that the origins of Hungarian and Finnish are in Yakutia, Siberia, far from Western Europe

A major study in Nature analyzes hundreds of ancient genomes and traces an east-west migration that shaped the Finnish, Estonian and Hungarian languages. The findings connect to the Saimaa-Turbino networks and the Yamania expansion, and also offer early clues to a Dana-Yenisei connection.

New research reveals unusual clustering pattern in sparse dwarf galaxies – and may indicate that dark matter acts differently than we thought, perhaps even interacting with itself
An artist's impression shows the internal structure of Jupiter's moon Io. Data from NASA's Juno spacecraft indicate that Io does not have a shallow global magma ocean, and is consistent with a mostly solid mantle (shown in green), with significant molten material (yellow and orange), above a liquid core (red/black).

How cosmic collisions created the largest galaxies in the universe

  • No comments
The study suggests that these galaxies were formed from large flows of cold gas and collisions between galaxies in the early universe, which led to the formation of stars at an extremely fast rate

An artist's rendering of the planet 8 Ursae Minoris b - also known as "The Goddess" - within the debris field after a violent merger of two stars. The planet may have survived the merger, but it is also possible that it is an entirely new planet formed from the fragments. Illustration: Kek Observatory/Adam Makarenko
