Physicists at Fermilab Discover New Subatomic Particle

http://www.foxnews.com/scitech/2011/07/21/physicists-at-fermilab-discover-new-subatomic-particle/?test=faces


High-speed collisions at a giant atom smasher have produced what physicists say is a new particle, a heavier relative of the familiar neutron.
The particle is called the neutral Xi-sub-b. When it's formed in the Fermilab Tevatron particle accelerator in Batavia, Ill., the neutral Xi-sub-b lasts just a mere instant before decaying into lighter particles. Scientists at Fermilab uncover these ephemeral particles by racing particles around a 4-mile (6.3 km) ring at near light speed. When the particles collide, the outpouring of energy disintegrates them into other particles.

The Interactive Library is about "real interactivity"! The database contains hundreds of activities that make use of sophisticated java, vrml and shockwave prgrams.
If you are unfamiliar with java or shockwave take a look at these sample programs.
-Teachers Create your own activity sheet to go with the programs and your students are set for a new experience.
-Students Use these programs to supplement your classroom activities, or use one of the more advanced applets as a starting point for your science project.
-Parents Use these programs to supplement your childs homework.

Planets may be vastly more numerous than believed

Researchers say that millions of Jupiter-sized planets are wandering in our galaxy far from any star. The findings suggest that there may be twice as many planets as stars in the Milky Way, perhaps several times as many.

The Earth Charter Initiative

“The Earth Charter Initiative” is an extraordinarily diverse, global network of people, organizations, and institutions that participate in promoting and implementing the values and principles of the Earth Charter.
The Earth Charter is a declaration of fundamental ethical principles for building a just, sustainable and peaceful global society in the 21st century. It seeks to inspire in all people a new sense of global interdependence and shared responsibility for the well-being of the whole human family, the greater community of life, and future generations. It is a product of a decade-long, worldwide, cross cultural dialogue on common goals and shared values.
