Surprising ring sheds light on galaxy formation
The question of what triggers the extremely rapid star formation within Hyper Luminous Infrared Galaxies (HyLIRGs), as yet unknown, is of much interest to guide our understanding of the formation and evolution of galaxies in the universe. A new photo.....»»
Insight into one of life"s earliest ancestors revealed in new study
An international team of researchers led by the University of Bristol has shed light on Earth's earliest ecosystem, showing that within a few hundred million years of planetary formation, life on Earth was already flourishing......»»
Observation of 3D acoustic quantum Hall states
The quantum Hall effect (QHE) is one of the most notable discoveries in condensed matter physics, opening the door to topological physics. Extending QHE into three dimensions is an inspiring but challenging endeavor. This difficulty arises because th.....»»
Hexagonal metallic-mean approximants help bridge gap between quasicrystals and modulated structures
For a long time, scientists associated crystal structures with an ordered arrangement of atoms in a repeating lattice-like pattern, believing it to be the most stable configuration. However, by the 1960s, advancements in crystallography revealed mate.....»»
A new species of extinct crocodile relative rewrites life on the Triassic coastline
The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, U.S., rewrites the story of life along the coasts during the first act of the Age of Dinosaurs......»»
Astronomers find the nearest massive black hole, a missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed.....»»
Visualizing the boundary modes of the charge density wave in a topological material
Charge density waves are quantum phenomena occurring in some materials, which involve a static modulation of conduction electrons and the periodic distortion of the lattice. These waves have been observed in numerous condensed matter materials, inclu.....»»
New probe reveals water-ice microstructures
Ice is believed to have played a crucial role in the emergence of life. One reason is that organic molecules can be excluded into the gaps between the crystal lattice by orderly arranged water molecules, leading to the concentration of organic compou.....»»
Recovery of unique geological samples sheds light on formation of today"s Antarctic ice sheet
In recent years, global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its fo.....»»
3D covalent organic frameworks with zyg topology for photocatalytic synthesis of hydrogen peroxide
A research team proposed a new synthetic strategy of COFs based on a new topology that remotely separates donor (D) and acceptor (A) units in 3D lattice to produce the expected metastable photo-induced charge-separated states......»»
A 4,500-year-old collective tomb in France reveals final stage in formation of the "European genome"
High-resolution analysis of the genomes of individuals buried in a 4,500-year-old collective tomb at Bréviandes-les-Pointes, near the French town of Troyes, has revealed a surprising story with far-reaching implications. As detailed in an article in.....»»
