1 Nano 'pin art': NIST arrays are step toward mass production of nanowires
NIST researchers grow nanowires made of semiconductors -- gallium nitride alloys -- by depositing atoms layer-by-layer on a silicon crystal under high vacuum. NIST has the unusual capability to produce these nanowires without using metal catalysts, thereby enhancing luminescence and reducing defects. NIST nanowires also have excellent mechanical quality factors. Source: PhysOrg

2 Scientists find metallic magnet with largest yet atomic displacement during thermal expansion
(PhysOrg.com) -- Although most materials change shape in the presence of a magnetic field, the change is usually very small. In a new study, scientists have found that a certain magnet containing manganese experiences a change in the distance between two neighboring atoms of up to 2%, which is the largest ever found in a metallic magnet. Magnets with large magnetoelastic interactions - the ... Source: PhysOrg

3 Calcium supplements play an important role in maintaining bone health
A broad range of scientific research has demonstrated that an adequate intake of calcium plays an important role in building and maintaining optimum bone mass, and a recent meta-analysis published online in the British Medical Journal should not cause consumers to doubt the value of calcium supplements for maintaining bone health.

8 California is the primary US stop for LHC's ALICE data
For approximately one month a year, the nuclei of lead atoms traveling near the speed of light will collide in the Large Hadron Collider's (LHC) ALICE experiment, generating a fireball about 100,000 times hotter than the core of our Sun. At these temperatures protons and neutrons dissolve into a "particle soup" of quarks and gluons, known as the quark-gluon plasma -- a state of matter that first ... Source: PhysOrg
