Neuroscientists Improve Touch Sensitivity in Mice

Neuroscientists Improve Touch Sensitivity in Mice

Neuroscientists from Brown University show that faint sensations can be made more vivid by triggering a brain rhythm that appears to shift sensory attention in mice. This newly published study provides the first direct evidence that the brain’s “gamma” rhythms have a causal role in processing the sense of touch. Providence, Rhode Island (Brown University) […]

Pebble-Size Particles May Represent a New Class of Interstellar Particles

New GBT Observations Show Pebble-Size Particles May Jump Start Planet Formation

A team of astronomers has discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles. If confirmed, these particles may represent a new class of interstellar particles that could help jump-start planet formation. Rocky planets like Earth start out as microscopic bits of dust tinier than a grain of […]

New Calculations Challenge Assumptions about Rigid Lithosphere

New Calculations Show Pacific Plate Shrinking as it Cools

A newly published study from geophysicists Rice University and the University of Nevada challenge assumptions about a rigid lithosphere, revealing that the Pacific plate is shrinking as it cools. Houston – The tectonic plate that dominates the Pacific “Ring of Fire” is not as rigid as many scientists assume, according to researchers at Rice University […]

Indications of Water Clouds in a Brown Dwarf 7 Light-Years from Earth

Astronomers Detect Evidence of Water Clouds in Brown Dwarf Atmosphere 7 Light Years from Earth

A team of astronomers has discovered indications of water clouds in the coldest known brown dwarf, which is located 7.3 light-years from Earth. Astronomers have found signs of water ice clouds on a brown dwarf located just 7.3 light-years from Earth. If confirmed, the discovery is the first sighting of water clouds beyond our solar […]

New ScienceCasts Video: Evidence for Supernovas Near Earth

The Local Bubble and the Galactic Neighborhood

A new four minute ScienceCasts video examines evidence that our solar system is inside a bubble of hot gas created by supernova explosions. ScienceCasts: Evidence for Supernovas Near Earth. A NASA sounding rocket has confirmed that the solar system is inside an ancient supernova remnant. Life on Earth survived despite the nearby blasts. Once every […]

X-Rays from Eta Carinae Reveal Clues about the Double Star System

Chandra Views the Eta Carinae Star System

The Eta Carinae star system reveals new clues about its nature through the X-rays it generates, including how the winds from the stars interact. The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the […]

New Image Provides the Best View Yet of Merging Galaxies in Distant Universe

New View of Merging Galaxies in the Distant Universe

Astronomers have obtained the best view yet of a collision that took place between two galaxies when the Universe was only half its current age. Using the Atacama Large Millimeter/submillimeter Array (ALMA), and many other telescopes on the ground and in space, an international team of astronomers has obtained the best view yet of a […]
