NASA's Webb Telescope's Last Backbone Component Completed

Assembly of the backbone of NASA's James Webb Space Telescope, the primary mirror backplane support structure, is a step closer to completion with the recent addition of the backplane support frame, a fixture that will be used to connect all the pieces of the telescope together.

Students and Teachers Become Rocket Scientists at NASA's Wallops Flight Facility

More than 120 students and educators will delve into the world of rocket science June 15-21 during Rocket Week at NASA's Wallops Flight Facility on Virginia's Eastern Shore.

Spot-welding graphene nanoribbons atom by atom

Scientists have created single atom contacts between gold and graphene nanoribbons.

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.
