Paleontologists have announced the discovery of a new species in the tyrannosaurid dinosaur genus Labocania, based on a partial skeleton found in Coahuila, Mexico. The newly-discovered dinosaur ...

Geological observations of Mars indicate a dense early atmosphere ranging from 0.25 to 4 bar of carbon dioxide. But 3.5 billion years ago, the Martian atmosphere thinned rapidly to approximately 0.054 ...

A team of archaeologists from the University of Chester, Heneb: the Trust for Welsh Archaeology and the Portable Antiquities Scheme has uncovered the ruins of a Roman settlement and a rare Medieval ...

Astronomers using the Keck II 10-m telescope have discovered evidence for an Earth-mass planet and a brown dwarf orbiting a white dwarf star. The planet has a mass of 1.9 Earth masses and orbits the ...

Until now, the fungus gnat genus Robsonomyia was represented by two living species: Robsonomyia reducta from North America and Robsonomyia sciaraeformis from Asia. Paleontologists have now found two ...

Based on multiple analytical techniques applied to well-preserved soft-bodied specimens of two trilobite species, the Late Ordovician species Triarthrus eatoni and the Middle Cambrian species ...

Breakup of an asteroid passing within Earth’s Roche limit likely formed the debris ring during the middle Ordovician period, according to new research from Monash University. All large planets in our ...

The images in the Martian Cloud Atlas have been captured by the High Resolution Stereo Camera (HRSC) instrument on ESA’s Mars Express spacecraft. Due to the elliptical orbit of Mars Express, its HRSC ...

Bubble use evolved in many small invertebrates to enable underwater breathing, but, until recently, there has been no evidence that vertebrate animals use bubbles in a similar manner. Only one group ...

Martian ‘spiders’ are small, dark, spider-shaped features up to 1 km (0.6 miles) across. The leading theory is that they form when spring sunshine falls on layers of carbon dioxide deposited over the ...

The Horned Serpent panel at La Belle France in the Free State province of South Africa was painted by the San people at least two hundred years ago. It pictures, among many other elements, a tusked ...

In the Standard Model of particle physics, the masses of the carriers of the weak interaction, the W and Z bosons, are uniquely related. Physics beyond the Standard Model can change this relationship ...
