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 ...

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 ...

The top image shows interstellar comet 3I/ATLAS as seen with MIRI (Mid-Infrared Instrument) on NASA’s James Webb Space Telescope, along with contours that illustrate where different gases were located ...

Like on a Ferris wheel, a powerful terahertz laser drives the atoms of a crystal along precise circular paths. The resulting collective oscillation of the crystal lattice was traced stroboscopically ...

Beamforming, introduced in WiFi 5, works by having devices share details about how signals travel through their environment. This creates a new source of information for WiFi sensing, but it also ...
