Israeli archaeologists uncovered a large subterranean gallery during pre-construction salvage excavations. Its age, purpose and builders remain a mystery.
A large underground tunnel was found beneath a future construction site in Jerusalem.
Salvage excavations were conducted by the Israel Antiquities Authority before building work began.
The tunnel's origin, age and function remain unknown pending further research.
American researchers have built a tool that more accurately estimates true biodiversity, including species that elude direct observation during field surveys.
The model estimates undetected species using detection patterns of known ones.
Absence from data is treated as a probability, not as proof of non-existence.
The method works on existing datasets, requiring no additional fieldwork costs.
Astronomers have found the first solid evidence linking a long-period radio transient to a violent astrophysical event, shedding light on one of astronomy's enduring puzzles.
First direct evidence links a long-period radio transient to a cosmic cataclysm.
LPRTs pulse at unusually long intervals — minutes to hours — unlike ordinary pulsars.
The finding could turn these signals into tools for detecting violent events across the universe.
The experimental aircraft completed its first supersonic test flight in California, a milestone for a programme aiming to bring back commercial supersonic travel over land.
X-59 broke the sound barrier for the first time, flying from Edwards Air Force Base, California.
The aircraft is engineered to sharply reduce the sonic boom associated with supersonic speed.
The Quesst programme aims to overturn a 50-year ban on commercial supersonic flights over land.
Global demand for minerals used in consumer electronics is accelerating deforestation in the Congo Basin, eroding natural barriers between humans and deadly viruses.
Mining-driven deforestation in the Congo Basin expands contact between humans and natural Ebola virus reservoirs.
Cobalt and gold from the region are used in batteries found in smartphones sold worldwide.
Researchers warn that the deforestation 'edge effect' increases both the frequency and scale of Ebola outbreaks.
A newly described four-winged microraptor species from northwestern China provides fresh clues about how dinosaurs first took to the air 120 million years ago.
The 120-million-year-old Chinese fossil belongs to a new species named Jian changmaensis.
Microraptors had four feathered limbs that enabled them to glide through the air.
The find helps clarify evolutionary links between feathered dinosaurs and early birds.
Chinese researchers published in Communications Psychology found that heavy consumption of short videos — TikTok, Reels, Shorts — impairs information retention compared to longer video formats.
Short-form videos reduce information retention compared to longer video content.
Brains trained on short content process fast but consolidate less into long-term memory.
The study, published in Communications Psychology, was conducted by Chinese researchers.
The Mark-0 prototype reached criticality — the point at which a nuclear chain reaction becomes self-sustaining — in what is a first for a private American company.
Antares reached criticality with the Mark-0 prototype, the essential first step toward a working reactor.
Criticality means the nuclear chain reaction sustains itself without external energy input.
This is the first time a private US company has achieved this milestone with a micro-reactor.
