Cosmic Turbulences within “Dead Zones” Result Black Hole and Star Formation

Research Shows Cosmic Turbulences Result in Star and Black Hole Formation

New research from physicists at Helmholtz-Zentrum Dresden-Rossendorf looks at how magnetic fields can cause turbulences within “dead zones,” resulting in the formation of black holes and other objects in the cosmos. Just how stars and black holes in the Universe are able to form from rotating matter is one of the big questions of astrophysics. […]

Physicists Teleport Information in a Solid State System

Physicists Teleport Information in a Solid State System

Using a device similar to a conventional computer chip, physicists have for the first time successfully teleported information in a so-called solid state system. ETH researchers cannot ”beam“ objects or humans of flesh and blood through space yet, a feat sometimes alluded to in science fiction movies. They managed, however, to teleport information from A […]

Hubble Data Reveals Galaxies Had ‘Mature’ Shapes 11.5 Billion Years Ago

Hubble Data Reveals that Mature Galaxies Existed Over 11 Billion Years Ago

Using data from the Hubble Space telescope, astronomers show that galaxies had “mature” shapes 11.5 billion years ago. Studying the evolution and anatomy of galaxies using the Hubble Space Telescope, an international team of astronomers led by doctoral candidate BoMee Lee and her advisor, professor Mauro Giavalisco, have established that mature-looking galaxies existed much earlier […]

Chandra Discovers Dwarf Galaxy Colliding into NGC 1232

Chandra Spots Dwarf Galaxy Colliding with NGC 1232

A new study reveals that a giant cloud of superheated gas, which is about 6 million degrees, is likely the result of a collision between a dwarf galaxy and a much larger galaxy called NGC 1232. Observations with NASA’s Chandra X-ray Observatory have revealed a massive cloud of multimillion-degree gas in a galaxy about 60 […]

Liquid Crystal Matrix Slows Light to Less Than One Billionth of Its Top Speed

Researchers Slow Light to a Crawl

Using embedded dye molecules in a liquid crystal matrix, an international team of researchers slowed the speed of light to less than one billionth of its top speed. Washington, August 13, 2013 — Light traveling in a vacuum is the Universe’s ultimate speed demon, racing along at approximately 300,000 kilometers per second. Now scientists have […]

Newly Discovered Small Molecule Inhibitor Boosts Insulin Signaling

Newly Discovered Small Molecule Boosts Insulin Signaling

Harvard Medical School researchers have uncovered a new pathway in insulin resistance and show that a newly discovered small-molecule inhibitor can interrupt this pathway and increase insulin signaling. Insulin resistance unleashes a vicious cycle in Type 2 diabetes whereby excess blood sugar induces the release of yet more insulin by the pancreas. A primary goal […]

Scientists Discover a Tiny Twist in Bilayer Graphene, Solve a Long-Standing Mystery

Scientists Discover a Tiny Twist in Graphene

Berkeley Lab researchers have solved a long-standing puzzle, discovering that in the stacking of graphene monolayers subtle misalignments arise, creating an almost imperceptible twist in the final bilayer graphene that prevents the graphene from becoming fully insulating even under a very strong electric field. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National […]
