Unlike most gamma-ray bursts, which are caused by exploding massive stars or the chance mergers of neutron stars, a long gamma-ray burst event dubbed GRB...
The center of the Milky Way Galaxy hosts Sagittarius A*, a supermassive black hole with a mass of about 4 million solar masses that is very quiescent....
New research shows how the nematode Caenorhabditis elegans, a long-used model organism, can use electric fields to ‘jump’ across Petri plates or onto...
The rusty patched bumblebee (Bombus affinis) is an important pollinator in North America and a federally listed endangered species. Putting together its...
Ancient horses such as Hyracotherium leporinum, a tiny horse relative from the Eocene of England, had feet like those of a modern tapir: four toes in front...
Contrastingly, for healthy patients and those with only slightly blocked carotid arteries, exercise is beneficial for maintaining healthy blood flow.

Aerial parts of plants arrange their organs around stems, and this arrangement defines their structure. In most existing plant species, organs emerge at...
White dwarf pulsars include a rapidly spinning, burnt-out stellar remnant called a white dwarf, which lashes a companion red dwarf with powerful beams...
Paleontologists have studied the unusual necks of two species of Tanystropheus, a type of aquatic reptile that lived during the Triassic period some 242...
Many planetary scientists studying Jupiter’s moon Europa assumed that it formed with a metallic core during or shortly after accretion. New research...

Earth’s rotational pole has drifted toward 64.16°E at a speed of 4.36 cm per year during 1993-2010 due to groundwater depletion and resulting sea level...
Phosphorus has not previously been detected in oceans beyond those on Earth and this discovery provides a promising step forward in our understanding of...
Humans whose genetic ancestors lived outside Africa have a small proportion of the genome that traces back to interbreeding events with Neanderthals. To...
Plate tectonics is a fundamental factor in the sustained habitability of Earth, but its time of onset is unknown, with ages ranging from the Hadean to...
New research from the University of Toronto suggests that the so-called clumpiness problem, which centers on the unexpectedly even distribution of matter...
Soft tissues rarely preserve in the fossil record, rather scientists are mostly left with just the skeletal material. Yet, muscles animate the body. They...
In a new study, paleontologists from the United Kingdom and Sweden reviewed the fossil evidence of locomotion of kangaroos and their relatives (wallabies,...
