The first transcontinental telegraph message was sent in 1861, bringing to an end the Pony Express

The Pony Express was a fast mail service crossing the Great Plains and the Rocky Mountains from St. Joseph, Missouri, to Sacramento, California, from April 1860 to October 1861. It became the west's most direct means of east-west communication before the telegraph and was vital for tying California closely with the Union just before the American Civil War.

This original fast mail Pony Express service had messages carried by horseback riders in relays to stations across the prairies, plains, deserts, and mountains of the Western United States. For its 18 months of operation, it briefly reduced the time for messages to travel between the Atlantic and Pacific coasts to about ten days, with telegraphic communication covering about half the distance across the continent and mounted couriers the rest.

2010 Nobel Prize Winners in Physics Announced

The Nobel Prize in Physics 2010 was awarded jointly to Andre Geim and Konstantin Novoselov "for groundbreaking experiments regarding the two-dimensional material graphene"

Graphene is a one-atom-thick planar sheet of carbon atoms that are densely packed in a honeycomb crystal lattice. The term Graphene was coined as a combination of "graphite" and the suffix "ene" (containing a double carbon bond).

The possible practical applications (though most of them sill not realized) for graphene include microelectronics, composite materials, solar cells, mobile phones, and more.

Chile's Trapped Miners are Free!

On August 5, 2010 33 Chilean miners ranging in ages from 19 to 63 became trapped 700 metres (2,300 ft) below the ground surface in a copper and gold mine located in the Atacama Desert. The trapped miners gained contact with the outside world 17 days after the mine collapse through a 3-inch diameter hole that was drilled to reach the trapped miners. Through this hole, the trapped miners have received food and other supplies. A video message released to the public on August 26, 2010 showed the miners living conditions 2,300 feet below the ground surface.

At approximately 11:30 pm on 12 October 2010 (Eastern Daylight Time) the first of the trapped miners reached the surface, after an approximately fourteen-minute ascent in the rescue Fenix capsule. All of the remaining miners were rescued successfully within 21 hours of the first miner's arrival on the surface.

2010 Nobel Prize Winners in Chemistry are Announced

This year's Nobel Prize in Chemistry is awarded to Richard F. Heck, Ei-ichi Negishi and Akira Suzuki for the development of palladium-catalyzed cross coupling.

Carbon is a stable element and carbon atoms do not easily react with one another. In this method carbon atoms bind to a palladium atom, an act that brings together the carbon atoms and starts the reaction that ends up with a new carbon-based material.

This chemical method is very useful for the electronics, platics and medicine industries.
