The Saharo-Arabian Desert is one of the largest biogeographical barriers on Earth, impeding dispersals between Africa and Eurasia, including movements of past hominins. Recent research suggested that ...

A new study by University of California, San Diego computational astrophysicist Ethan Nadler shows that star formation can occur in halos down to 10 million solar masses through molecular hydrogen ...

A diverse array of animals has evolved the ability to use tools (e.g., primates, parrots, octopus, crabs, and wasps), but the factors leading to tool use evolution are poorly understood. Fishes could ...

A Martian dust devil can be seen consuming a smaller one in a series of images taken by a navigation camera aboard NASA’s Perseverance rover. Dust devils are formed by rising and rotating columns of ...

Challenging assumptions about infant memory, a new Yale University-led study shows that infants as young as 12 months old can encode memories. The findings suggest that infantile amnesia — the ...

“Planetary nebulae are the spectacular final display at the end of a giant star’s life,” Hubble astronomers said in a statement. “Once a red giant star has exhausted its available fuel and shed its ...

A satiety-inducing molecule called bombesin is not only present in humans and other vertebrates but also in invertebrates such as starfish and their marine relatives, according to new research.

“Nobody had really considered the possibility of convection in the crust of Venus before,” said Washington University in St. Louis Professor Slava Solomatov. “Our calculations suggest that convection ...

A new species of the wukongopterid pterosaur genus Darwinopterus has been identified from an almost complete skeleton found in western Liaoning, China. The newly-discovered species lived in what is ...

The newly-discovered shape-recovering liquids defy long-held expectations derived from the laws of thermodynamics, according to a team of physicists at the University of Massachusetts Amherst.

Apes and monkeys possess special anatomical structures in their throats called vocal membranes, which disappeared from humans through evolution to allow for more stable speech. However, the exact ...

The quantum superposition principle allows us to prepare a system in a superposition of two arbitrary states. The paradigmatic example is the superposition of two coherent states. While the ...
