In search of life beyond our solar system: Atmosphere detected on a habitable-zone rocky world

First atmosphere detected on a habitable-zone rocky world
In this artist’s concept, the exoplanet LHS 1140 b is shown in the foreground, surrounded by a helium-rich atmosphere. Another nearby rocky planet orbits the same cool red dwarf star in the distance. A new study provides the strongest evidence yet that LHS 1140 b has retained an atmosphere, representing a milestone step toward the discovery of Earth-like rocky planets beyond our solar system.

In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of another star...

Physicists say quantum mechanics may not need imaginary numbers after all

Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In the scientific journal Physical Review Letters, they show that this theory does not necessarily need to be formulated with imaginary numbers – real numbers can in fact also be used.

Quantum mechanics is the branch of physics that explains how matter and energy behave at the atomic and subatomic scale. Developed in the early 1900s by pioneers including Max Planck, Niels Bohr, Werner Heisenberg, and Erwin Schrödinger, it has become one of the most successful scientific theories ever created.

The theory accurately describes a wide range of microscopic phenomena...

Sugar-free diets may disrupt the gut microbiome, animal study indicates

Eliminating sugar from your diet may be more detrimental than previously thought, according to an animal study presented at ENDO 2026, the Endocrine Society’s annual meeting in Chicago.

“Completely removing sucrose from a low-fat diet may unexpectedly disrupt gut health and promote inflammation and metabolic dysfunction, highlighting that balanced nutrition is more important than simply eliminating sugar,” said Rasheed Ahmad, Ph.D., principal scientist and head of the Immunology & Microbiology Department at the Dasman Diabetes Institute in Kuwait City, Kuwait. The institute was founded by Kuwait Foundation for the Advancement of Sciences.

Researchers investigated the effects of a sucrose-free low-fat diet compared with a sucrose-containing low-fat control diet in two groups of m...

A joint research team has experimentally observed ballistic transport in single-crystalline copper thin films, demonstrating that ballistic transport is achievable in an industry-standard metal at interconnect-relevant dimensions. The study, titled “Ballistic transport in nanodevices based on single-crystalline Cu thin films,” was published in Nature Communications.

Ballistic transport r...
