NASA's Hubble Uncovers Evidence of Farthest Planet Forming From Its Star

Astronomers using NASA's Hubble Space Telescope have found compelling evidence of a planet forming 7.5 billion miles away from its star, a finding that may challenge current theories about planet formation.

Warm Ocean, Not Icebergs, Causing Most of Antarctic Ice Shelves' Mass Loss

Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent's ice shelf mass loss, a new study by NASA and university researchers has found.

Discovery of new material state counterintuitive to laws of physics

When you squeeze something, it gets smaller -- unless you're among a group of scientists who have seemingly defied the laws of physics and found a way to apply pressure to make a material expand instead of compress/contract.

New 31-km-long International Linear Collider ready for construction

Today the Linear Collider Collaboration published its Technical Design Report [PDF] for the International Linear Collider (ILC) - a proposed 31-kilometer electron-positron collider that will both complement and advance beyond the physics of the Large Hadron Collider.

New quantum dot technique combines best of optical and electron microscopy

Researchers have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture to image nanoscale features. Combining the best features of optical and scanning electron microscopy, the fast, versatile, and high-resolution technique allows scientists to view surface and subsurface features potentially as small as 10 nanometers in size.

Massive particle storage ring to begin 3,200-mile trek on Sunday

(Phys.org) —How do you move a 50-foot-wide, circular electromagnet from Long Island to the Chicago suburbs in one piece without flexing or twisting it? Very, very carefully.

Molecular 'sieves' harness ultraviolet irradiation for greener power generation

New research shows that exposing polymer molecular sieve membranes to ultraviolet (UV) irradiation in the presence of oxygen produces highly permeable and selective membranes for more efficient molecular-level separation, an essential process in everything from water purification to controlling gas emissions.

Global quantum networks based on optical fibers: Scientists quantum mechanically couple atoms to glass fiber cables

Researchers have quantum mechanically couple atoms to glass fiber cables. Now, they have shown that their technique enables storage of quantum information over a sufficiently long period of time to realize global quantum networks based on optical fibers.

NASA'S Chandra Turns up Black Hole Bonanza in Galaxy Next Door

Using data from NASA's Chandra X-ray Observatory, astronomers have discovered an unprecedented bonanza of black holes in the Andromeda Galaxy, one of the nearest galaxies to the Milky Way.

Incoherent combining of fiber lasers developed for directed energy applications

Developed at the U.S. Naval Research Laboratory, Plasma Physics Division, incoherent combining of high power fiber lasers for directed energy (DE) weapons and power beaming have proven effective in laser weapon systems (LaWS) prototypes now being temporarily deployed onboard select Navy ships.
