A proposed industrial-scale green hydrogen and ammonia project in Chile that astronomers warned could cause “irreparable damage” to the clearest skies in the world has been cancelled. The decision by AES Andes, a subsidiary of the US power company AES Corporation, to shelve plans for the INNA complex has been [...]

High-energy heavy-nuclei collisions, conducted at particle colliders such as CERN’s Large Hadron Collider (LHC) and BNL’s Relativistic Heavy Ion Collider (RHIC) are able to produce a state of matter called a quark-gluon plasma (QGP). A QGP is believed to have existed just after the Big Bang. The building blocks of protons and [...]

In quantum mechanics, a quantum state is a complete description of a system’s physical properties. If the system changes slowly and returns to its original physical configuration, then its quantum state also returns to its original form except for a phase factor. In a pioneering work in 1984, physicist Michael Berry discovered that this factor can be [...]

Radiation therapy is usually delivered by prescribing the same radiation dose for each particular type of tumour. But this “one-size-fits-all” approach does not account for a tumour’s intrinsic radiosensitivity and heterogeneity and can lead to recurrence and treatment failure. Researchers in Sweden and Germany are now investigating whether biologically individualized [...]

Researchers from Columbia University and Breakthrough Listen, a scientific research program aimed at finding evidence of civilizations beyond Earth, have published new results from the Breakthrough Listen Galactic Center Survey, one of the most sensitive radio searches ever conducted for pulsars in the dynamically complex central region of the Milky [...]

Entanglement is a key resource for quantum computation and quantum technologies, but it can also tell us much about a computational problem. That is the conclusion of a recent paper by Achim Kempf and Einar Gabbassov – who are applied mathematicians at Canada’s University of Waterloo and are affiliated with [...]

The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international team led by Nikolaus Sulzenauer and Axel Weiß from the Max Planck Institute for Radio Astronomy (MPIfR) used data from the Atacama Large Millimeter/submillimeter Array (ALMA) to shed light on this open [...]

Enßlin, Gordian Edenhofer 2026, A&A, 706, A161 Superclouds are the largest structures identified so far in the interstellar medium. With typical sizes of a [...]

Active link Bromo volcano in East Java, Indonesia, which is the most volcanically active country in the world, where heavy rainfall has triggered explosive activity and eruptions at active volcanoes. (Courtesy: iStock/Panya_) A few years ago, Swiss seismologist Verena Simon noticed a striking shift in the pattern of seismic activity and [...]

Author(s): Philip BallBefore determining the correct quantum theory of gravity, researchers need to know if gravity is actually quantized. Experiments testing that assumption are now being developed.[Physics 19, 18] Published Tue Feb 10, 2026 [...]

The near and far sides of the Moon are very different in their chemical composition, their magmatic activity and the thickness of their crust. The reasons for this difference are not fully understood, but a new study of rocks brought back to Earth by China’s Chang’e-6 mission has provided the [...]

Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It is the second-highest-energy cosmic ray ever observed, carrying around 40 million times more energy than particles accelerated [...]

A supermassive black hole with a case of cosmic indigestion has been burping out the remains of a shredded star for four years—and it's still going strong, new research led by a University of Oregon astrophysicist shows. [...]
