First Proton Collisions in the LHC

Posted on November 25, 2009 by Rashid Faridi

The world’s largest particle accelerator has performed its first collisions, and its first beam acceleration.Progress on the giant experiment has been rapid in the four days since the Large Hadron Collider (LHC) was restarted.According to several sources, these low-energy collisions weren’t expected for another two weeks, but LHC scientists and engineers were obviously very confident that they could put the delay to an end and start smashing protons today.

Can the Sun Help Turn Carbon Dioxide Into Fuel?

Posted on November 25, 2009 by Rashid Faridi

U.S. researchers have demonstrated a technology that uses the sun’s heat to convert carbon dioxide and water into the building blocks of traditional fuels, a reverse combustion process that may emerge as a practical alternative to sequestration of CO2 emissions from power plants.

Bad News :Oceans Absorb Less Carbon Dioxide as Marine Systems Change

Posted on November 24, 2009 by Rashid Faridi

The oceans are largest carbon sink on the planet. Some 93 percent of carbon dioxide is stored in algae, vegetation, and coral under the sea. But oceans are not able to absorb all of the carbon dioxide released from the burning of fossil fuels. A recent study suggests that the oceans have absorbed a smaller proportion of fossil-fuel emissions, nearly 10 percent less, since 2000.

The study, published in the current issue of Nature, is the first to quantify the perceived trend that oceans are becoming less efficient carbon sinks. The study team, led by Columbia University oceanographer Samar Khatiwala, measured the amount of human-caused carbon dioxide emissions pumped into the oceans since 1765.

25 Everyday Technologies That Came from NASA

Posted on November 24, 2009 by Rashid Faridi

Though associated mainly with aerospace innovations, NASA holds a significant influence over daily life as well. Many people do not realize that everything from toys to sunglasses and even horseshoes have benefitted from technologies originally intended for astronauts, shuttle flights, and other elements of space exploration. While some inventions stem directly from NASA and its collaborations, others simply involve vast improvements to existing designs. ….
