Stephen Hawking believes that one of the major factors in the possible scarcity of intelligent life in our galaxy is the high probability of an asteroid or comet colliding with inhabited planets. We have observed, Hawking points out in Life in the Universe, the collision of a comet, Schumacher-Levi, with Jupiter (below), which produced a series of enormous fireballs, plumes many thousands of kilometers high, hot "bubbles" of gas in the atmosphere, and large dark "scars" on the atmosphere which had lifetimes on the order of weeks. It is thought the collision of a rather smaller body with the Earth,...

DEPRESSION! Why don’t politicians tell the TRUTH, the WHOLE TRUTH and NOTHING BUT THE TRUTH?!?! I must report that in my visits throughout the Detroit area to get to talk with people, I hear the word, “DEPRESSION” again and again… they are NOT using the OFFICIAL TERM, “recession.” Ha! Dah! I think WE THE PEOPLE KNOW something that our government leaders do NOT know… or, perhaps, want to cover up… what do YOU think? HOPE you will comment NOW! I am in Detroit, MI area this week teaching my regular AP US Government & Politics Seminar for Teachers. This is...

Powered up: An amorphous layer (light-colored band at the right) on a crystalline battery material improves its performance. Credit: Byoungwoo Kang, MIT A lithium-ion battery electrode described this week in the journal Nature can deliver electricity several times faster than other such batteries. It could be particularly useful where rapid power bursts are needed, such as for laser weapons or hybrid race cars. Test batteries based on the new electrode--developed by Gerbrand Ceder, a professor of materials science at MIT--can be discharged in 10 seconds. In comparison, the best high-power lithium-ion batteries today discharge in a minute and a...

Great Apes Think Ahead: Conclusive Evidence Of Advanced Planning CapacitiesIn a series of four experiments, Mathias and Helena Osvath investigated whether chimpanzees and orangutans could override immediate drives in favor of future needs, and therefore demonstrate both self-control and the ability to plan ahead, rather than simply fulfill immediate needs through impulsive behavior. (Credit: iStockphoto/Michael Steden) ScienceDaily (Jun. 19, 2008) — Apes can plan for their future needs just as we humans can – by using self-control and imagining future events. Mathias and Helena Osvath’s research, from Lunds University Cognitive Science in Sweden, is the first to provide conclusive evidence...

VIENNA (Reuters) - Iran is testing an advanced centrifuge at its Natanz nuclear complex, diplomats said on Wednesday, a move that could lead to Tehran enriching uranium much faster and gaining the means to build atom bombs. Iran says it wants nuclear energy only for electricity so it can export more oil. But it is under sanctions for hiding the program until 2003, preventing U.N. inspectors since then from verifying it is wholly peaceful and refusing to suspend it. Tehran's quest to produce usable amounts of nuclear fuel has been hampered by problems getting a 1970s vintage of centrifuge, the...

Stone Age site yields evidence of advanced culture (Xinhua) Updated: 2007-05-04 20:48 Chinese archaeologists say they have uncovered strong evidence that Stone Age people in southern East Asia were at least as technologically advanced as their European cousins -- challenging the long-standing theory of "two cultures". Excavations at the Dahe Stone Age site, in southwest China's Yunnan Province, had revealed elaborate stone tools and instruments that rivaled those of the Mousterian culture that existed at that time in Europe, said Ji Xueping, chief archaeologist at the site. Dated as 36,000 to 44,000 years old, the Dahe site has since 1998...

Metallurgy in ancient India was advanced HT Correspondent Varanasi, January 25 EMINENT METALLURGICAL engineer and former rector of the Banaras Hindu University Prof TR Anatharaman said that ancient India contributed a lot in the field of metallurgy. He was delivering a lecture on ‘Metallurgical Marvels of Ancient India’ on the third-day of four-day seminar on ‘History of Indian Science and Technology’ at Swatantrata Bhawan in BHU here on Thursday. Prof Anatharaman, also former director of Institute of Technology (IT-BHU) and presently Chancellor of Ashram Atmadeep (Gurgaon) said that recent historical studies and scientific researches have thrown considerable new light on...
