LinkNotes: Quantum Halllike effect found in a bulk material without an applied magnetic field

Rob Jongschaap — Sun, 27 Apr 2008 08:58:42 +0000

A team of scientists from Princeton University has found that the so called quantum Hall effect, which is observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields can occur in a bulk crystal...

Earth's innards as steamy and hot as our sun!

The catalogue of extrasolar planets is growing continuously, containing more than 200 objects, and the detection of these exoplanets has almost become a routine. However, what are the characteristics of the stellar hosts, how can we explain...

Saturn's Northern Lights Also Move in Reverse

Irani — Wed, 08 Mar 2006 05:14:27 +0000

Auroras on Earth happen, leaving the gazers pondering on the ever-happening outer world. But, when does it happen? It is when the solar wind interacts with our planet’s magnetic field; electrons are accelerated downwards into the atmosphere,...

Magnetic Fields Shape Out Narrow Jets From Dying Star

Irani — Fri, 03 Mar 2006 01:27:48 +0000

Molecules spew outward from a dying star. These molecules are confined into narrow jets by a tightly-wound magnetic field. Astronomers used the National Science Foundation’s Very Long Baseline Array (VLBA) radio telescope to find this, while...

North Pole is Shifting Rapidly: It May Move to Siberia In 50 Years

Irani — Sat, 17 Dec 2005 05:02:09 +0000

North Pole shifting! Yes, it is. The north magnetic pole is shifting rapidly towards Russia. And it is moving at rapid clip-25 miles (40 kilometers) a year, new research shows. It is only over the past century, the pole has moved as much as 685...
