From Live Science:

New research by Boldizsár Jankó, a professor of theoretical physics at The University of Notre Dame, and his colleagues offers an important breakthrough in understanding an enduring mystery in physics.

More than a century ago, at the dawn of modern quantum mechanics, the Noble Prize-winning physicist Neils Bohr predicted “quantum jumps.” Since the early 1990s, researchers have been able to view such jumps as interruptions of the continuous emissions from single molecules, a phenomenon informally called “blinking”. However, while some blinking can be directly ascribed to Bohr’s original quantum jumps, many observations do not follow predictions.

What Caused The Calif. Natural Gas Explosion?

From Discovery News:

A horrific explosion in San Bruno, Calif., yesterday initially prompted fears of an airplane crash. The source turned out to be a ruptured natural gas line, but what failure actually caused the deadly, Bruckheimer-like scene?

Pacific Gas and Electric Company, PG&E, told the Associated Press that a 30-inch gas pipe had ruptured several feet underground. PG&E told reporters that the blast originated in a steel gas pipeline about two feet in length, but they don't know the cause yet because the fire was still going this morning.

30 Ways The World Could End

From Discover Magazine:

Crank up the gloom and doom: Global apocalypse could be just around the corner, and you might never see it coming—unless you read this article.

Fashions come and go in all human endeavors—even eschatology, the study of the end of the world.

Back in the 1980s, our planet seemed sure to perish in a nuclear barrage, and songs about atomic apocalypse were at the top of the charts: Cue Prince’s “1999” (“Everybody’s got a bomb/We could all die any day”). By the 1990s, death by asteroid impact was all the rage. After 9/11 and the 2001 anthrax attacks, worries turned to a bioweapon unleashed by a terror group. The latest obsession is plague, delivered in the metaphorical form of vampires and zombies—especially zombies, since vampires have developed an unseemly fondness for chaste romance.

US Navy Seeks 'Safer' Bomb

From New Scientist:

COULD a variable-yield bomb reduce the number of innocent people killed or injured during an air attack targeting enemy soldiers? That's the thinking behind a US navy plan to develop a "dial-a-blast" bomb.

The navy is seeking proposals from companies to create a bomb weighing 200 kilograms that can either be detonated at full or reduced power. The idea is that the device could be loaded onto planes before a target has been identified, and the explosive power set by the pilot once a target is known. If there is a risk of killing civilians, then the explosive power can be reduced to ensure a small blast radius. In an unpopulated area the bomb, currently known as the Selectable Output Weapon, could be set so that it has the same power as a regular bomb of the same size. Carrying a single bomb would make it easier and cheaper for the navy to arm its planes.

From Fortune/CNN Money:

"I should be honest with you," Foxconn founder and chairman Terry Gou told Bloomberg Businessweek on the subject of the suicides at his company's massive factory complex in Shenzhen, China. "The first one, second one, and third one, I did not see this as a serious problem. We had around 800,000 employees, and here [in Longhua] we are about 2.1 square kilometers. At the moment, I'm feeling guilty. But at that moment, I didn't think I should be taking full responsibility." After the fifth suicide, in March, Gou says, "I decided to do something different."

Artificial Intelligence: Riders On A Swarm

From The Economist:

Mimicking the behaviour of ants, bees and birds started as a poor man’s version of artificial intelligence. It may, though, be the key to the real thing.

ONE of the bugaboos that authors of science fiction sometimes use to scare their human readers is the idea that ants may develop intelligence and take over the Earth. The purposeful collective activity of ants and other social insects does, indeed, look intelligent on the surface. An illusion, presumably. But it might be a good enough illusion for computer scientists to exploit. The search for artificial intelligence modelled on human brains has been a dismal failure. AI based on ant behaviour, though, is having some success.

From Air & Space Magazine:

A veteran reporter describes his search for the aircraft of Area 51.

"And you'll see a very long runway right...there." Our aircraft commander jabbed a finger at a small, cross-hatched circle on the U.S. Air Force navigation chart. "But, even if we lose all four engines," he said, "we will not land on it.”

“Why not, sir?” I asked.

“We’d be there a long time and have to answer a lot of questions,” the commander replied, then moved on to the next day’s mission preview. A four-stripe sergeant leaned toward me. “That’s Groom Lake,” he said under his breath. “That’s where the really secret [stuff] happens.”

Mining The Truth On Coal Supplies

From National Geographic:

A view that the world’s leading electricity fuel—and major contributor to climate change—is running out.

This story is part of a special series that explores energy issues. For more, visit The Great Energy Challenge.

No matter how bad coal might be for the planet, the conventional wisdom is that there is so much of it underground that the world’s leading fuel for electricity will continue to dominate the energy scene unless global action is taken on climate change.

But what if conventional wisdom is wrong?

A new study seeks to shake up the assumption that use of coal, the most carbon-intensive fossil fuel, is bound to continue its inexorable rise. In fact, the authors predict that world coal production may reach its peak as early as next year, and then begin a permanent decline.

A Cellular Secret To Long Life

From Science News:

Just as proper storage keeps a loaf fresh longer, adequate packaging may be a key to cellular longevity, reports a study of the organisms that make bread rise.

New research on aging in baker’s yeast suggests that proper packaging of DNA can halt aging and lead to longer life. The study, published September 10 in Molecular Cell, shows that a decline in levels of DNA-packaging proteins called histones is partially responsible for aging, and that making more of the proteins can extend the life-span of yeast.
