By destabilizing superconductivity with a strong magnetic field, the electrons of a "high temperature" superconductor align into linear filaments. This phenomenon has been demonstrated by a team of researchers at the CNRS Laboratoire National des Champs Magnetiques Intenses. Published in Nature on the 8 September 2011, these results add a new piece to the puzzle that condensed-matter physicists have been trying to put together for nearly twenty-five years.

Editor's Note: The following is an excerpt from Mara Hvistendahl's book , Unnatural Selection: Choosing Boys over Girls and the Consequences of a World Full of Men. The technology that ultimately became the dominant method of sex selection around the world began as a tool for navigation. The story of ultrasound dates to 1794, when an Italian biologist curious about how bats find their way in the dark discovered sonar, or the fact that distance can be determined by bouncing sound waves off a faraway object and measuring how long it takes for the waves to ricochet back

The sisterhood of women is weak in the workplace, according to many new studies including one where 95 percent of women said they felt undermined at some point in their career by other women. This phenomenon has a name: The Queen Bee Syndrome.

On April 8, 1911, at the Leiden Cryogenic Laboratory in the Netherlands, Heike Kamerlingh Onnes and his collaborators immersed a mercury capillary in liquid helium and saw the mercury's electrical resistance drop to nothing once the temperature reached about 3 kelvins, or 3 degrees above absolute zero (around –270 Celsius). This phenomenon of "superconductivity" was one of the first quantum phenomena to be discovered, although back then quantum theory did not exist. In subsequent decades theoreticians were able to put quantum physics on a solid foundation and explain superconductivity.
