AstroPhysics: La profesora del millón de dólares

La astrofísica Kelly Holley-Bockelman, de la Universidad de Vanderbilt (Estado de Tennessee) ha obtenido la dotación más elevada de la historia para profesores jóvenes, en el área de astronomía, que otorga la Fundación Nacional para la Ciencia de Estados Unidos. Son más de un millón de dólares que destinará a proseguir sus estudios sobre los agujeros negros y a financiar el programa que pretende conseguir que su universidad sea la que produzca más doctores en física y astronomía de las minorías sociales hasta ahora discriminadas.

CLIMATE CHANGE IS NATURAL: 100 REASONS WHY

HERE are the 100 reasons, released in a dossier issued by the European Foundation, why climate change is natural and not man-made: 1) There is “no real scientific proof” that the current warming is caused by the rise of greenhouse gases from man’s activity.

E=mc2 is Wrong – Einstein’s “Special Relativity” Fundamentally Flawed

Is Albert Einstein’s Special Relativity incompatible with the very equations upon which science’s greatest theory is built ?. New observations made by many scientists and engineers appear to contradict the great German scientist’s ideas. Apparently there are implicit contradictions present within Relativity’s foundational ideas, documents and equations. One individual has even pointed that quotations from the 1905 document and Einstein’s contemporaries as well as interpretations of the Relativity equations clearly and concisely describe a confused and obviously erroneous theory. It is time therefore, for science to update its thinking on this theory with a comprehensive analysis of the history leading up to, during and after that revolutionary year of Special Relativity.

Brain Stimulation with Infrared Light

Researchers have recently found that infrared light has the capability of stimulating brain cells. Infrared light causes the excitation of neurons thus altering their activity. This new type of brain stimulation method is referred to as infrared nerve stimulation (INS). INS has a variety of applications for altering the functioning of central nervous system disorders. For many brain disorders, brain activity is altered in comparison to more normal states. Infrared light has a very high selectivity and can target very small sub-populations of brain cells. This type of stimulation could potentially reduce many of the side effects of current brain stimulation.

Synthetic magnetism achieved by optical methods: Technique enables unprecedented insights

For the first time, physicists have used laser light to create  synthetic magnetism , an exotic condition in which neutral atoms suddenly begin to behave as if they were charged particles interacting with a magnetic field -- even though no such field is present and the atoms have no charge. The achievement provides unprecedented insights into fundamental physics and the behavior of quantum objects, and opens up entirely new ways to study the nature of condensed-matter systems that were barely imaginable before.
