Mars –Things Fall Apart

Tharsis Tholus, a giant Martian volcano towering almost 5 miles (8 km) in height, shows signs of much dramatic activity in its four-billion-year history. At least two large sections have collapsed around its eastern and western flanks, as evidenced by scarps up to several miles high. Researches believe that the volcano emptied its magma chamber during eruptions and, as the lava escaped, the chamber roof could no longer support its own weight. Thus, the volcano collapsed, forming the large caldera.

Google-x-logoGoogle X -A  Lab of Wildest Dreams

In a top-secret lab in an undisclosed Bay Area location where robots run free, the future is being imagined. Google is said to be considering the manufacture of its driverless cars in the United States. Sergey Brin, one of Google's founders, is said to be deeply involved in Google X. It’s a place where your refrigerator could be connected to the Internet, so it could order groceries when they ran low. Your dinner plate could post to a social network what you’re eating. Your robot could go to the office while you stay home in your pajamas. And you could, perhaps, take an elevator to outer space. These are just a few of the dreams being chased at Google X, the clandestine lab where Google is tackling a list of 100 shoot-for-the-stars ideas.

201006_invisibleCarbon nanotube sheets create invisibility

Dr. Ali Aliev, a research scientist at UT Dallas, and colleagues have demonstrated that transparent carbon nanotube sheets can be used to make objects invisible. This invisibility for light oblique to the nanotube sheets is caused by the mirage effect (photothermal deflection), in which a thermally generated refractive index gradient bends light array from a hidden object. “The remarkable performance of nanotube sheets suggests possible applications as photo-deflectors and for switchable invisibility cloaks, and provides useful insights into their use as thermoacoustic projectors and sonar,” the authors say.







Global-warming-information-kidsWorld Energy Outlook 2011

Without a bold change of policy direction, the world will lock itself into an insecure, inefficient and high-carbon energy system, the International Energy Agency warned in the 2011 edition of the World Energy Outlook (WEO).

The average oil price remains high, approaching $120/barrel (in year-2010 dollars) in 2035.
Oil demand rises from 87 million barrels per day (mb/d) in 2010 to 99 mb/d in 2035, with all the net growth coming from the transport sector in emerging economies. With oil production declining in all existing fields, an increasing share of liquid fuels will come from natural gas liquids and oil sands, with Russia’s role as a supplier of natural gas more pivotal.In the WEO’s central New Policies Scenario, which assumes that recent government commitments are implemented in a cautious manner, primary energy demand increases by one-third between 2010 and 2035, with 90% of the growth in non-OECD economies.

Amazon-Kindle-Fire-ThumbAmazon Owns the Web in More Ways Than You Think

The release today of Amazon'x new Kindle Fire is not just a rival gadget, but something essentially different. The iPad is the flagship of the post-PC era—in which the desktop is replaced by lean, portable, gesture-driven tablets. As people will learn when Amazon ships it today, November 14, the Fire is an emblem of a post-web world, in which our devices are simply a means for us to directly connect with the goodies in someone’s data center.
