Altermagnetism is a distinct form of magnetic order where the tiny constituent magnetic building blocks align antiparallel to their neighbors, but the structure hosting each one is rotated compared to ...

Nicknamed the Firefly Sparkle, the newly-discovered galaxy existed approximately 600 million years after the Big Bang and consisted of a least 10 star clusters. The most distant galaxies detected are ...

In a genomic study encompassing more than 300 genomes, researchers determined the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about ...

The Atacama Trench stretches along the eastern South Pacific Ocean, plunging to depths exceeding 8,000 m off the coast of northern Chile. The hadal zone, or the deepest 45% of the ocean (6,000-11,000 ...

Dark comets are small bodies with no detected coma that have significant accelerations explainable by outgassing of volatiles, analogous to the first interstellar object 1I/2017 U1 ‘Oumuamua. These ...

Fossil records show that dinosaurs evolved during the middle part of the Triassic period (247 to 237 million years ago). However, the domination of dinosaurs in terrestrial ecosystems was not seen ...

New research led by University of Bristol scientists sheds light on how lepidosaurs — the most diverse clade of tetrapods, including lizards and snakes — have evolved remarkably varied jaw shapes, ...

Planetary researcher Tereza Constantinou and her colleagues at the University of Cambridge have examined the chemical composition of the Venusian atmosphere and inferred that the planet’s interior is ...

Consumption of at least five servings of dark chocolate a week (one serving is equal to a standard chocolate bar/pack or 1 oz) compared with rare consumption was significantly associated with lower ...

New research by scientists from the University of Reading and the University of Durham shows that encephalization (i.e., relative brain size increase) across 7 million years of hominin evolution arose ...

Over its history, archaeology has seen a varied set of uses made of philosophy and philosophical concepts. A persistent critique has been that too often philosophical or more generally theoretical ...

Contradicting the results of several recent studies, the new findings reopen the case that Jupiter-family comets like 67P/Churyumov-Gerasimenko could have helped deliver water to Earth. Water was ...
