September 21, 2006 | User rating: 3.9 / 5 after 154 vote(s) | No comments yet

Two researchers from The College of Judea and Samaria in Israel have designed an ink-jet printer head that could lead to printers capable of chugging out 1,000 pages per minute – or even more.


Evidence of a Bose glass state?

May 30, 2008 | User rating: 4.5 / 5 after 51 vote(s) | User comments: 1

"In nano-sized systems many physical properties are greatly altered from those of macroscopic-sized systems. Therefore, study of nano-sized systems, in general, is very important in developing fundamental physics," Keiya ...


Physicists Build a Quantum Gambling Machine

April 30, 2008 | User rating: 3.9 / 5 after 33 vote(s) | User comments: 3

Quantum gambling machines may not be popping up at futuristic casinos any time soon, but the devices could have other uses – such as enabling physicists to study game theory in situations where cheating is ...


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, ...


Scientists model molecular switch

June 16, 2008 | User rating: 4.7 / 5 after 15 vote(s) | User comments: 2

Michigan Technological University physicist Ranjit Pati and his team have developed a model to explain the mechanism behind computing's elusive Holy Grail, the single molecular switch.


New theory (and old equations) may explain causes of ship-sinking freak waves

September 13, 2006 | User rating: 4.5 / 5 after 152 vote(s) | No comments yet

On a stormy April day in 1995, the RMS Queen Elizabeth 2 was sailing in the North Atlantic when the ocean liner dipped into a "hole in the sea." Out of the darkness, a towering 95-foot wave threatened to crash ...


Before the Big Bang: A Twin Universe?

April 09, 2008 | User rating: 4.3 / 5 after 266 vote(s) | User comments: 30

Until very recently, asking what happened at or before the Big Bang was considered by physicists to be a religious question. General relativity theory just doesn’t go there – at T=0, it spews out zeros, infinities, ...


Light-emitting transistor uses light to transfer an electrical signal

November 01, 2006 | User rating: 4.5 / 5 after 105 vote(s) | No comments yet

In one of the early discoveries of the current "silicon electrophotonics era," scientists from Hitachi, Ltd. in Tokyo have built a light-emitting transistor (LET) that transfers, detects and controls an electrical ...


Physicists Predict Stock Market Crashes

February 24, 2006 | User rating: 4 / 5 after 217 vote(s) | No comments yet

On Monday, October 19, 1987 – infamously known as “black Monday” – the Dow fell 508 points, or 22.9%, marking the largest crash in history. Using an analytical approach similar to the one applied to explore ...


Protons Pair Up With Neutrons

May 29, 2008 | User rating: 4.3 / 5 after 21 vote(s) | User comments: 6

Research performed at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility has found that protons are about 20 times more likely to pair up with neutrons than with other protons in ...


Nuisance noise silenced by an acoustic cloak

June 13, 2008 | User rating: 4.6 / 5 after 27 vote(s) | User comments: 4

Researchers in Spain have proven that metamaterials, materials defined by their unusual man-made cellular structure, can be designed to produce an acoustic cloak - a cloak that can make objects impervious to sound waves, ...


Single-particle interference observed for macroscopic objects

September 28, 2006 | User rating: 4.7 / 5 after 125 vote(s) | No comments yet

With a variation on the famous double-slit experiment of quantum mechanics, scientists Yves Couder and Emmanuel Fort from the University of Paris 7 are rewriting the textbooks. Their accomplishment, however, ...
