Researchers Look Beyond the Birth of the Universe

May 12, 2006 | User rating: 4.6 / 5 after 184 vote(s) | No comments yet

According to Einstein’s general theory of relativity, the Big Bang represents The Beginning, the grand event at which not only matter but space-time itself was born. While classical theories offer no clues ...


Can Newton's 2nd Law be Violated on Earth?

March 20, 2007 | User rating: 3.6 / 5 after 117 vote(s) | No comments yet

Astrophysicists have found evidence that a corrected version of Newton’s 2nd Law (which deals with the acceleration of mass) works well on the grand scale of the universe. These modifications to Newtonian physics are known ...

'It might be life Jim...', physicists discover inorganic dust with life-like qualities

August 09, 2007 | User rating: 4.7 / 5 after 180 vote(s) | No comments yet

Could extraterrestrial life be made of corkscrew-shaped particles of interstellar dust? Intriguing new evidence of life-like structures that form from inorganic substances in space are revealed today in the New Journal ...


Quantum mechanics may explain how humans smell

February 01, 2007 | User rating: 4.5 / 5 after 102 vote(s) | No comments yet

Scientists from the London Centre for Nanotechnology (LCN) at University College London have newly analyzed an intriguing 10-year-old theory of smell, finding that the idea may make more sense than once thought.


Particle decay may point to New Physics

October 11, 2006 | User rating: 4.7 / 5 after 142 vote(s) | No comments yet

A tiny flaw has caught the attention of physicists: the Standard Model (SM) predicts that the B meson mixing phase should be measured at nearly the same result using two different classes of decay modes. However, ...


Professor proposes theory of unparticle physics

June 11, 2007 | User rating: 4.5 / 5 after 196 vote(s) | No comments yet

Howard Georgi, a physicist at Harvard University, has recently published a paper on so-called unparticle physics, which suggests the existence of “unparticle stuff” that cannot be accounted for by the standard ...


Engineers set new world record in generation of high-frequency submillimeter waves

April 16, 2007 | User rating: 4.6 / 5 after 86 vote(s) | No comments yet

Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have achieved a new world record in high-frequency submillimeter waves. The record-setting 324-gigahertz frequency was accomplished using a voltage-controlled ...


Researchers may have solved information loss paradox to find black holes do not form

June 20, 2007 | User rating: 4.2 / 5 after 115 vote(s) | No comments yet
