People Hanging Out More On Facebook Than Google

From CNET:

Internet users are spending a bit more time these days socializing on Facebook than searching on Google, according to new data from market researcher ComScore.

In August, people spent 41.1 million minutes on Facebook, accounting for 9.9 percent of the total number of minutes they spent online for the month. That inched past the 39.8 million minutes, or 9.6 percent of total time, that Net users spent on all of Google's sites combined, including its search engine, YouTube, Gmail, and Google News, ComScore said Thursday.

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.”

What Killed The Mammoths? Alien Nanodiamonds May Hold The Answer

Wooly Mammoth Did nanodiamonds mean death for this mammoth and all his friends? Depends on which study you believe. Wikimedia Commons

From Popular Science:

Do nanodiamonds prove an asteroid impact killed off North America's massive mammals 13,000 years ago? It depends on which scientist you ask.

A pair of studies published in the last month offer competing theories about whether an extraterrestrial object killed megafauna like woolly mammoths and sabre-toothed cats, along with the Clovis culture of North American human settlers.

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.

From New Scientist:

A CELESTIAL event in the 5th century BC could be the earliest documented sighting of Halley's comet - and it marked a turning point in the history of astronomy.

According to ancient authors, from Aristotle onwards, a meteorite the size of a "wagonload" crashed into northern Greece sometime between 466 and 468 BC. The impact shocked the local population and the rock became a tourist attraction for 500 years.

Herb Quells Cows' Methane-Laden Belches

From Live Science:

For scientists concerned about greenhouse gas emissions, cow farts are nowhere near as problematic as their methane-laden belches. Now a new oregano supplement could stem the burps and reduce the potent methane emissions.

Worldwide, cows are responsible for 37 percent of the human-produced methane, according to study researcher Alexander Hristov, an associate professor of dairy nutrition at Penn State University. Most of that methane comes not from the backsides of cows, but from the gas they belch after digesting their food, according to Hristov and the Food and Agriculture Organization of the United Nations.

Warming Solution: Just Stop Cold?

From National Geographic:

The greatest climate threat is from future cars and building, study says.

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

Imagine that tomorrow, the whole world will stop building things that burn fossil fuels—cars and planes, power plants, and housing tracts.

How much more global warming would the planet endure?

(See Related, from National Geographic Channel: "Aftermath: Population Zero" )

This might sound like an environmentalist's dream—or a CEO's nightmare—but it's a serious question addressed by a new study published in the September 10 issue of Science.

Skydiving From The Edge Of Space: Can A Human Break The Sound Barrier?

From The Guardian:

A person freefalling from 120,000 feet would theoretically reach a supersonic speed of over 700mph. Two daredevils of the skies are racing to break the sound barrier – and face unknown hazards in their attempt.

We know this. At around 120,000 feet, on the fringes of space, the air is so thin that a falling human body would travel fast enough to exceed the speed of sound. A skydiver, properly equipped with pressurised suit and a supply of oxygen to protect against the hostile elements, could feasibly jump from that height and, about 30 seconds later, punch through the sound barrier – becoming the first person ever to go "supersonic" without the aid of an aircraft or space shuttle.
