From Live Science:

Although ships sail on the ocean, they can leave tracks in the sky. On Oct. 5, a NASA satellite snapped a shot of this phenomenon forming in a bank of clouds off North America’s west coast.

The white trails look vaguely like the condensation trails, or contrails, left behind by airplanes, but they actually result from ship exhaust.

The Coming E-Reader Wars


Investing In The e-Reader Battle? Bet On Barnes & Noble -- Wall Street Journal

Crazy? That's what Wall Street thinks—analysts love Amazon, but have little to say about its competitor. But that's why buying Barnes & Noble may be a smart move. Some of the best profits come from going against the crowd.

Everybody loves Amazon's booming stock, which has doubled so far this year. But that run-up in value has made it dangerously expensive. By contrast, few adore Barnes & Noble shares, so they've been left for dead. When you run the numbers, the stock looks remarkably cheap.

Building A Bridge Of (And To) The Future

HOLDING UP The Neal Bridge is taking the daily onslaught of traffic in Maine.
Craig Dilger for The New York Times


From The New York Times:

PITTSFIELD, Me. — The Neal Bridge is barely a bump in the road for motorists roaring down Route 100 south of this central Maine town. It’s a modest bit of the nation’s infrastructure — two lanes wide and 34 feet long, enough to span a small stream.

The bridge is newer than most, as suggested by the still-black asphalt and the fresh galvanized gleam of the guardrails. But it’s what is underneath that really makes the bridge stand out.

Peer-to-Peer Passé, Report Finds

From Epicenter/Wired:

Peer-to-peer file sharing has been the bogeyman of the internet, but a new report suggests it’s destined become a fear of the past — replaced by cheap streaming video.

Rising from the ashes in the early 2000s of banned services like Napster, P2P soon became demonized as an imminent threat to software industry, Hollywood and the internet’s backbone, prompting high-profile piracy trials, federal government hearings on traffic management and hand-wringing from ISPs who said torrents of illicit traffic would overwhelm the net.

Out Of Your Head: Leaving The Body Behind

Peculiar experiences (Image: Christian Lichtenberg/Getty)

From New Scientist:

THE young man woke feeling dizzy. He got up and turned around, only to see himself still lying in bed. He shouted at his sleeping body, shook it, and jumped on it. The next thing he knew he was lying down again, but now seeing himself standing by the bed and shaking his sleeping body. Stricken with fear, he jumped out of the window. His room was on the third floor. He was found later, badly injured.

The Chemistry of Information Addiction


From Scientific American:

A new experiment reveals why we always want to know the answer.


My mother is a more patient human being after having raised a child who incessantly asked, “Are we there yet?” That information, often out of reach for a frustrated toddler, carries with it a feeling of reward. The majority of us are all too familiar with the urge to know more about the future, whether it is an exam grade, an experimental result, or the status of a new job.

Flu Vaccines Hit A Wall

From Technology Review:

As new influenza strains emerge, researchers struggle to speed vaccine development.

Making a vaccine against seasonal influenza is a constant catch-up game. Scientists must predict which of the constantly mutating virus strains will be most virulent six months in the future, the amount of time it takes to manufacture the vaccine. The system has worked well enough for the regular flu. But when new, virulent strains emerge--including the current, rapidly spreading swine flu (H1N1)--the traditional approach falls short. Even as consumers clamored for a vaccine, it took seven months and around 48,000 confirmed U.S. cases before the first H1N1 vaccines were shipped to hospitals around the country.

Reports Of American Longevity Greatly Exaggerated


From Live Science:

Americans got a bit of good news this month: Half the kids born today in wealthy countries could live at least 100 years. The other half might live long, too.

This respite from otherwise grim news of, say, increasing slaughter and insurgency in Afghanistan, where life expectancy is 44 years, came courtesy of a study published by European researchers in the journal the Lancet.

Brain Food: Can Maths Really Let You See Into The Future?

From The Guardian:

Meet the professor who can seemingly predict political events using a laptop.

Let's start with some news from the near future. Iran won't build a nuclear bomb. With extra aid money, Pakistan will become more peaceful. And the Copenhagen summit on climate change this December is doomed to failure.

If Bruce Bueno de Mesquita is right, those are the headlines you'll be reading over the next few months. The author of a new book called Predictioneer, he makes big-picture forecasts employing maths, and a laptop that has been so heavily used its letters have worn away.

From Discovery Magazine:

It's taken 25 years, but a new solar-thermal plant in New Mexico has finally broken the old efficiency record.

In 1986 solar panels were literally ripped from the White House roof. But political will and financial incentives have reignited the search for efficient, affordable ways to harness the sun’s energy. Two new solar thermal technologies—which focus sunlight to create heat rather than convert it directly to electricity, as photovoltaics do—promise to make solar power practical at vastly different scales.

The Fusion Illusion -- A Commentary

From The New Atlantis:

To hear President Barack Obama tell it, we need to fundamentally overhaul the way we produce, deliver, and consume energy. After the House of Representatives passed the Waxman-Markey cap-and-trade bill in June, the president said it would “spark a clean energy transformation in our economy. It will spur the development of low carbon sources of energy—everything from wind, solar, and geothermal power to safer nuclear energy and cleaner coal. It will spur new energy savings, like the efficient windows and other materials that reduce heating costs in the winter and cooling costs in the summer. And most importantly, it will make possible the creation of millions of new jobs.” He repeated those sentiments before the G-8 in Italy several weeks later when he stated, “One of my highest priorities as president is to drive a clean energy transformation of our economy.”

Energy Crisis Is Postponed As New Gas Rescues The World

Oil shale is rock containing deposits of oil and is pictured here burning.

From The L.A. Times

Engineers have performed their magic once again. The world is not going to run short of energy as soon as feared.


America is not going to bleed its wealth importing fuel. Russia's grip on Europe's gas will weaken. Improvident Britain may avoid paralysing blackouts by mid-decade after all.

The World Gas Conference in Buenos Aires last week was one of those events that shatter assumptions. Advances in technology for extracting gas from shale and methane beds have quickened dramatically, altering the global balance of energy faster than almost anybody expected.
