The Story Of A Life-Long Bump Hunter

John Conway says, "I’ve been looking for the Higgs boson for almost 20 years" which sounds like a long time if you are a young scientist but I have a watch missing for 35, so it isn't that impressive. What is impressive his description of wh ...

Chaos On A Chip

For the first time physicists have shown that well structured chaos can be initiated in a photonic integrated circuit. Furthermore, this represents the first time scientists have been able to study optical chaos at gigahertz rates. The output of a semicon ...

Endless Universe Made Possible By New Model

A new cosmological model demonstrates the universe can endlessly expand and contract, providing a rival to Big Bang theories and solving a thorny modern physics problem, according to University of North Carolina at Chapel Hill physicists. The cyclic model ...

Sound Might Drive Supernovae Explosions

Scientists have made the astonishing discovery that sound might drive supernovae explosions. Their computer simulations say that dying stars pulse at audible frequencies – for instance, at about the F-note above middle C – for a split second before they b ...

Physicists Find Way To 'See' Extra Dimensions

Peering backward in time to an instant after the big bang, physicists at the University of Wisconsin-Madison have devised an approach that may help unlock the hidden shapes of alternate dimensions of the universe. A new study demonstrates that the shapes ...

Using Nano-magnets To Enhance Medical Imaging

Nanoscale magnets in the form of iron-containing molecules might be used to improve the contrast between healthy and diseased tissue in magnetic resonance imaging (MRI)--as long as the concentration of nanomagnets is carefully managed--according to a new ...

Measurements Recast Usual View Of Casimir-Polder Force In Quantum Mechanics

Physicists at JILA have demonstrated that the warmer a surface is, the stronger its subtle ability to attract nearby atoms, a finding that could affect the design of devices that rely on small-scale interactions, such as atom chips, nanomachines, and micr ...

Fermions Do Not Travel Together: Physicists Demonstrate Expected Effect Of Quantum Theory

Fermions tend to avoid each other and cannot "travel" in close proximity. Demonstrated by a team at the Institut d'optique (CNRS/Université Paris 11, Orsay-Palaiseau), this result is described in detail in the January 25, 2007 issue of Natu ...
