When building sensor networks, it can be extremely challenging for researchers to determine how the sensors should be arranged to obtain optimal results. New research proposes a new way to quantify the quality of sensor networks, and uses this method to suggest improvements to existing Dark Matter experiments.

Dinosaurs came to flourish during the Jurassic period after a volcanic eruption roughly 201 millions years ago wiped out many marine and land animals, leaving them able to evolve and grow. Now, further details about this eruption and the mass extinction have been revealed. A group of researchers demonstrated how low temperature magma slowly heated sedimentary rocks, causing high sulfur dioxide and low carbon dioxide emissions, a process which cooled the earth.

Astronomers have presented a new explanation for the mysterious downward-moving dark voids seen in some solar flares.

An international team of researchers has published comprehensive data on the search for dark matter using a worldwide network of optical magnetometers. According to the scientists, dark matter fields should produce a characteristic signal pattern that can be detected  by correlated measurements at multiple stations of the GNOME network.

New research has revealed how giant 50-ton sauropod dinosaurs, like Diplodocus, evolved from much smaller ancestors, like the wolf-sized Thecodontosaurus.

Using observations of Centaurus A, a nearby elliptical galaxy, obtained with the Gaia space telescope and ground-based instruments under the PISCeS survey, a team of astronomers presents an unprecedented number of globular cluster candidates in the outer regions of the galaxy. The findings provide astronomers with an even more detailed picture of galactic architecture and history of collisions and mergers.

Astronomers are one step closer to revealing the properties of dark matter enveloping our Milky Way galaxy, thanks to a new map of twelve streams of stars orbiting within our galactic halo.

Scientists took a closer look at the braincase of a dinosaur from Austria. The group examined the fossil with a micro-CT and found surprising new details: it was sluggish and deaf.

The two-meter skull of an enormous new ichthyosaur species, Earth's first known giant creature, reveals how both the extinct marine reptiles and modern whales became giants.

A new study has provided the most detailed timeline of mammal evolution to date.

A 72 to 66-million-year-old embryo found inside a fossilized dinosaur egg sheds new light on the link between the behavior of modern birds and dinosaurs, according to a new study.

A new bird-like dinosaur that used brute strength to overcome its prey has been found by palaeontologists combing through fossils found on the Isle of Wight, on the South Coast of Great Britain.

Astrophysicists suggest that primordial black holes account for all dark matter in the universe.

A study investigated the enigma of why sauropod fossils are only found at lower latitudes, while fossils of other main dinosaur types seem ubiquitously present, with many located in the polar regions.

Unlike our Sun, most stars live with a companion. Sometimes, two come so close that one engulfs the other -- with far-reaching consequences. When astronomers used the telescope Alma to study 15 unusual stars, they were surprised to find that they all recently underwent this phase. The discovery promises new insight on the sky's most dramatic phenomena -- and on life, death and rebirth among the stars.

A cosmic object originally classified as a gas and dust cloud actually consists of three stars and could resolve a controversy among astronomers.

A new concept has been developed that has the potential to assist new instruments in the investigation of fundamental science topics such as gravitational waves and dark matter.

Astronomers have found no trace of dark matter in the galaxy AGC 114905, despite taking detailed measurements over a course of forty hours with state-of-the-art telescopes.

Astronomers have discovered an unusually massive black hole at the heart of one of the Milky Way's dwarf satellite galaxies, called Leo I. Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all galaxies -- the building blocks of the universe -- evolve.

Mounded, luminous clouds of gas and dust glow in this Hubble image of a Herbig-Haro object known as HH 45. Herbig-Haro objects are a rarely seen type of nebula that occurs when hot gas ejected by a newborn star collides with the gas and dust around it at hundreds of miles per second, creating bright shock waves. In this image, blue indicates ionized oxygen (O II) and purple shows ionized magnesium (Mg II). Researchers were particularly interested in these elements because they can be used to identify shocks and ionization fronts. This object is located in the nebula NGC 1977, which itself is part of a complex of three nebulae called The Running Man. NGC 1977 -- like its companions NGC 1975 and NGC 1973 -- is a reflection nebula, which means that it doesn't emit light on its own, but reflects light from nearby stars, like a streetlight illuminating fog. Hubble observed this region to look for stellar jets and planet-forming disks around young stars, and examine how their environment affects the evolution of such disks.
