Pre-contact Central and South American dogs (Canis familiaris) — all dogs preceding contact with European settlers — descended from a single maternal lineage that diverged after dogs entered North ...

Physicists have achieved the first-ever real-time, 3D simulations of how intense laser beams alter the quantum vacuum — a state once assumed to be empty, but which quantum physics predicts is full of ...

The Sun rarely produced extreme solar particle events, orders of magnitude stronger than everything directly observed. Their enormous power can greatly distort the production of cosmogenic isotopes, e ...

Microplastics are new, emerging contaminants that are becoming detrimental to aquatic environments on a global scale. These water-insoluble, solid polymers less than 5 mm in size originate from the ...

The possibility that the entire Universe is informational in nature and resembles a computational process is a popular theory among a number of well-known figures. The thinking comes from within a ...

A team of geologists from Curtin University has discovered unequivocal evidence for a hypervelocity meteorite impact 3.47 billion years ago (Archean Eon) in the center of the Pilbara region in Western ...

As our Solar System orbits the Milky Way, it encounters various environments, including dense regions of the interstellar medium. These encounters can expose parts of the Solar System to the ...
