Two Moons Above Earth May Have Collided To Create One, Study Says -- L.A. Times

Scientists say such a collision could explain why the moon is lopsided and why its far side is covered with mountains.

Once upon a time, the sky above Earth may have held two moons — until they smashed into each other to create the lunar body we know today. Such a collision early in the solar system's history could explain why the moon is lopsided, and why its far side looks so different from the face we can see, according to a report in Thursday's edition of the journal Nature.

Bionic Microrobot Mimics the 'Water Strider' and Walks On Water -- Science Daily

ScienceDaily (Aug. 2, 2011) — Scientists are reporting development of a new aquatic microrobot that mimics the amazing water-walking abilities of the water strider -- the long-legged insect that scoots across the surface of ponds, lakes and other waterways. The bionic microrobot incorporates improvements over previous devices of this kind that position it as a prime candidate for military spy missions, water pollution monitoring, and other applications, the scientists say.

Their study appears in the journal ACS Applied Materials & Interfaces

Apollo Astronaut: End NASA, Start From Scratch -- Houston Chronicle

Not everyone is celebrating the 50th anniversary of Kennedy’s decision to go to the moon with best wishes for another century of NASA.

Harrison Schmitt, the 12th astronaut to walk on the moon and a former U.S. senator, has called for dismantling NASA and replacing it with a new agency devoted solely to deep-space exploration.

Its charter, he believes, should simply be:

Provide the People of the United States of America, as national security and economic interests demand, with the necessary infrastructure, entrepreneurial partnerships, and human and robotic operational capability to settle the Moon, utilize lunar resources, scientifically explore and settle Mars and other deep space destinations, and, if necessary, divert significant Earth-impacting objects.

My Comment: He makes some salient points. What is my take .... a new start and direction is definitely need (both psychologically and structurally) for the U.S. space program.

Searching For Cleopatra

The Search for Cleopatra Continues -- Past Horizons

A radar survey of the temple of Taposiris Magna, west of Alexandria in Egypt, was completed last month as part of the ongoing search for the tomb of Cleopatra and Mark Anthony. The expedition excavating the temple and its surrounding area is headed by Dr. Zahi Hawass and Dr. Kathleen Martinez from the Dominican Republic.

The recent radar survey is a significant step forward and was carried out by an Egyptian team, with American expert Dr. Roger Vickers serving as a consultant. The radar revealed three possible areas of interest where a tomb may be located. These locations have been passed to the archaeological team who received the results of the survey with great interest, and will begin excavation of the targets next week.

Tsunamis Buried Ancient Olympics Site -- Discovery News

A series of devastating tsunamis -- not an earthquake -- might have swept away the birthplace of the Olympic Games in ancient Greece nearly 1500 years ago, according to new findings.

Scholars have long assumed that Olympia, located at the confluence of the Kladeos and Alpheios rivers in the western Peloponnese, was destroyed by an earthquake in 551 AD and later covered by flood deposits of the Kladeos river.

Indeed the site where the first Olympic Games took place in 776 BC, was rediscovered only some 250 years ago, buried under 26 feet of sand and debris.

Are Internet Explorer Users Stupid?

Internet Explorer Users Are Stupid And Have An Average IQ Of Just 80, Aptitude Study Claims -- Daily Mail

Survey claims average IQ of browser's users is just 80

They have long had to grapple with a catalogue of bugs and viruses.
But now users of Internet Explorer have another reason to feel humiliated - they are more stupid too.

A study has found that those with Internet Explorer 6 installed on their computer typically have an IQ barely higher than 80 - which by some rankings makes them almost retarded.

This compares to those who used Firefox or Google’s Chrome who came in at around 110.

Will We One Day Be Able To Treat Aging?

Middle-aged and elderly people exercise during “Respect for the Aged Day” in Tokyo in 2005. Japan’s population is aging particularly quickly. The ratio of people younger than 20 compared to those older than 65 is shifting, from 9.3 in 1950 to a predicted 0.59 in 2025. If scientists succeed at slowing aging, this trend may well accelerate.

Aging: To Treat, Or Not To Treat? -- American Scientist

The possibility of treating aging is not just an idle fantasy.

The 20th century brought both profound suffering and profound relief to people around the world. On the one hand, it produced political lunacy, war and mass murder on an unprecedented scale. But there were also extraordinary gains—not least in public health, medicine and food production. In the developed world, we no longer live in constant fear of infectious disease. Furthermore, a Malthusian catastrophe of global population growth exceeding food production—a terrifying prospect predicted first in the 18th century—did not materialize. This is largely due to a steep decline in birth rates, for which we can thank the education, emancipation and rationality of women. Most people in the developed world can now expect to live long lives.

What Makes Guinness A Great Beer To Drink

The Fizzics Of Guinness -- The Guardian

Look closely at a pint of Guinness and tell me: do the bubbles go up, or do the bubbles go down? Why is the head coloured the way it is? Is foam a gas, liquid or solid? An Irish physicist discusses.

Last Friday, Andy Connelly published the wonderful guest blog essay, "The science and magic of beer". His piece reminds me of some of the discussions I had with my beer-brewing physicist and engineer friends when I was a grad student. For example, look closely at a pint of Guinness and tell me: do the bubbles go up, or do the bubbles go down? Why is the head coloured the way it is? Is beer foam a gas, liquid or solid? I thought you might enjoy this little video as a follow up, where an Irish physicist discusses the "fizzics" of bubble formation in Guinness beer:

The Big Bang In Pictures

Explosions in the sky: These images track the movement of particles during experiments at CERN, and could give some idea of how the Big Bang may have looked

The Big Bang In Pictures: Scientists Produce Computer Images Of Particle Explosions Similar to The Greatest Ever Galactic Light Show -- Daily Mail

It may look like a firework display in the night sky but these explosive images could be the closest we have yet come to snapshot from the birth of the universe itself.
The computer generated images are the result of the 'big bang' experiments performed by scientists at CERN, home of the Large Hadron Collider, in Geneva, Switzerland.
In trying to determine exactly how the universe came into existence, scientists have been recreating sub-atomic explosions - like the one that may have happened around the time of the big bang - using atom-sized particles of lead.

Will Cost Kill Hubble’s Successor? -- Cosmos

A plan to scrap the James Webb Space Telescope, the long-awaited and costly heir to NASA’s Hubble telescope.

TOUTED AS NASA'S replacement for the ageing Hubble Space Telescope, the James Webb Space Telescope, if deployed, would be 100 times more powerful than its iconic predecessor.

"It will have incredible sensitivity and spatial resolution, making it able to look back to the very earliest times in the universe," says Warrick Couch, an astronomer at Swinburne University of Technology in Melbourne.

Yet funding cuts now seriously threaten the telescope's future, already over budget and years behind schedule, with bleak implications for future U.S. investment in astronomy projects of this scale.
