Impurities and spin Hall effects in graphene

Impurities and spin Hall effects in graphene

Condensed matterMaterialsPhysicsQuantum physics

By DIPC

The interactions between moving charges and magnetic fields can be quite complicated; more if we consider the quantum effects. One example is the collection of Hall effects. There are analogues of these effects for spin and the detection of the most sophisticated one in graphene, where, at least, it should not be strong, is something […]

Dealing with fire in microgravity

Dealing with fire in microgravity

ChemistryPhysics

By Silvia Román

All we know about fire under Earth´s gravity must be questioned in microgravity. In fact, most of the well-known characteristics of fire behavior are driven by the effects of gravity. That´s why the science of combustion in low-gravity environments is an important field of knowledge for NASA studies when evaluating spacecraft safety. And, contrary to […]

Gravitational waves predicted by Einstein heard by LIGO Gravitational waves from the collision of two black holes about 1.3 billion years ago have been detected by Laser Interferometer Gravitational-Wave Observatory, or LIGO, confirming a prediction Albert Einstein made a century ago in his general theory of relativity. The sound came through as a chirp first […]

Unusual nasal dome allowed ancient beast to trumpet like a dinosaur An ancient wildebeest-like creature that lived during the Ice Age had an unusual skull shape that enabled it to bellow like a dinosaur, according to researchers who found the skull fossils on what is now Kenya’s Rusinga Island. Rusingoryx atopocranion, which lived between 75,000 […]

Noodle-, hazelnut-shaped plasma lenses may be hiding in Milky Way Scientists are learning more about the shape of mysterious plasma lenses, which seem to invisibly float around the Milky Way, detected through radio waves. Researchers were able to detect a lengthy lensing event that gave them an idea of the shapes of the lenses. Space.com […]

Fish communicate to stay close to each other Fish use calls to stick together as a group, a new study suggests. Researchers played recordings of bigeye vocalizations for captive wild bigeyes, and noted that their own vocalizations increased and they swam more closely together than they did when no recordings were played. “This study means […]

Ancient grooves may be evidence of dinosaur mating ritual Four sites found in Colorado exhibit fossilized grooves that may have been made by dinosaurs doing a bird-like mating dance more than 100 million years ago. Scientists say the gouges could have been made by theropods performing a mating ritual common to modern birds. The Washington […]
