Halo 18 is an example of a galaxy that had a head-on collision (see the panel at z=1.2) and had a disc flip (you can see this by comparing the disc orientation at z=1.4 and z=0). This image and Image ...

In the mudstones of St Bathans, Central Otago, scientists have uncovered a fossil goose that adds a surprising twist to the evolutionary story of New Zealand’s birds. The deposits, dating to the early ...

Scientists have successfully measured the magnetic field of the Lighthouse pulsar’s nebula using NASA’s IXPE. Their measurements confirm the theory that high-energy particles escape along the galaxy’s ...

The discovery also sheds light on why some people are disturbed by low-frequency noise while others barely notice it. If the ...

Exoplanet WD 1856 b, shown in this artist’s concept, is a gas giant that orbits its star at a distance 50 times closer than Earth orbits the Sun. Observations by NASA’s James Webb Space Telescope ...

The ocean floor is constantly growing, forged by magmas and stretched by tectonic forces at mid-ocean ridges (MORs). Yet despite their importance, these submarine boundaries remain among the hardest ...

Dark matter has long been considered the scaffolding of galaxy formation, dictating how stars and gas assemble. In the quiet outskirts of the NGC 1052 field, astronomers have uncovered yet another ...

The breakneck expansion of cloud computing and AI is straining global data centers. All this data has to be stored and processed, which consumes enormous amounts of electricity per year, driving ...

Cocaine use disorder (CUD) remains an intractable public health problem; the associated genetic etiology has not been largely detected. Using rat models, researchers in a new report charted DNA ...

In Down syndrome, a person has an extra copy of chromosome 21. It is still the most common live-birth survivable chromosomal disorder, with an incidence of about 1 in 700. It is known for more than ...

Ecologists have been warning for decades that the extinction of one species can bring down entire ecosystems. Models of mathematics have long predicted that a single organism could trigger a chain ...
