At Google, Doodling Is Real Work
From CNET:
MOUNTAIN VIEW, Calif.--They've celebrated Pac-Man's anniversary, Einstein's birthday, the World Cup, the Fourth of July, Persian New Year, the Olympics, U.S. elections, and just about everything in between. Who are they? Google's Doodlers, of course.
A band of artists whose job it is to translate special events into those colorful, whimsical versions of Google's corporate logo, the Doodlers almost certainly have one of the best jobs in the world.

Craigslist Puts "Censored" Tag On Adult Services Section
From CBS News:
Craigslist has deactivated its adult services section in the United States, leaving in its place the word "censored" in bold black and white.
It's still not clear whether this means that the classified ads site has taken down the section, something that 17 attorneys general recently demanded in an open letter. They said that Craigslist could not adequately block potentially illegal ads promoting prostitution and child trafficking.
Craigslist did not immediately return a request for comment.

Surveillance Tech Wirelessly Watches Over Older Parents
From The ABC News:
Telemonitoring: Video Cameras, Sensors Help Care for Aging Parents.
For 74-year-old Carol Brewer, welcoming a video camera into her living room wasn't easy.
She said she'd walk through her own home and wonder, "Am I dressed appropriately?"
But over time, she said, she grew accustomed to the little grey globe in the corner of the room and now credits it, in part, with helping her and her 78-year-old husband Ross, who is paralyzed from the waist down, continue to live in their Lafayette, Ind., home on their own.

'No Climate Link' To African Wars
A study suggests climate change is not responsible for civil wars in Africa, challenging widely held assumptions.
Climate change is not responsible for civil wars in Africa, a study suggests.
It challenges previous assumptions that environmental disasters, such as drought and prolonged heat waves, had played a part in triggering unrest.
Instead, it says, traditional factors - such as poverty and social tensions - were often the main factors behind the outbreak of conflicts.
The findings have been published in the Proceedings of the National Academy of Sciences (PNAS) in the United States.

My Comment: I think it is to early to say that climate change is not causing some African wars, on the flip side, it is also too early to say that it is. But according to the PNAS .... they are confident that there is no link at all.

How To tell Emergency Room Patients That They're Dying.
On television, the emergency room patients beat the odds. Their hearts get shocked back to life. Their organs get sewn up. They awaken to a handsome young physician's dazzling smile.
In real life, one in 500 ER patients—200,000 a year—dies under the bright lights of the emergency rooms. Another 500,000—3 percent—die during hospital stays following emergency treatment. Countless patients learn, from a doctor they have never seen before and may never see again, that they have fatal diseases. Others get treated, aggressively and repeatedly, for dangerous flare-ups in conditions like heart failure or emphysema without anyone having the time or the skills to explain that the chronic disease they have been living with is now the chronic disease that they are slowly dying from, a scenario Atul Gawande explored in his recent New Yorker piece on what doctors can do when they can no longer cure.

Eternal Black Holes Are The Ultimate Cosmic Safes
From The New Scientist:
If you wanted to hide something away for all eternity, where could you put it? Black holes might seem like a safe bet, but Stephen Hawking famously calculated that they leak radiation, and most physicists now think that this radiation contains information about their contents. Now, there may be a way to make an "eternal" black hole that would act as the ultimate cosmic lockbox.

Taking Cues From Medical Tech, Big Oil Could Use Nanoparticles to Hunt for Leftover Crude in Spent Wells
From Popular Science:
You can't throw a rock in the realm of biotech right now without hitting some scheme or another for tapping the unique properties of nanoparticles to hunt tumors, target drug delivery, or monitor the body internally for specific biomarkers. But a perhaps unlikely field of scientific exploration is also tapping these nano-biotechnology applications to search for the elusive hydrocarbons that are its lifeblood: the oil industry.

Can Nanotechnology Save Lives?
From The Smithsonian:
Harvard professor and scientific genius George Whitesides believes that nanotechnology will change medicine as we know it
Finding George Whitesides is often tricky even for George Whitesides. So he keeps an envelope in his jacket pocket. “I don’t actually know where I am in general until I look at it,” he says, “and then I find that I’m in Terre Haute, and then the question really is, ‘What’s next?’” During a recent stretch, the envelope revealed that he was in Boston, Abu Dhabi, Mumbai, Delhi, Basel, Geneva, Boston, Copenhagen, Boston, Seattle, Boston, Los Angeles and Boston.

5 Nanometer Computer Chips
From Future Pundit:
While Moore's Law for increasing computer chip transistor density won't go on for more than another 20 years it is still happening. Intel introduced 32 nanometer chips in 2009 and will introduce 22 nm chips in 2011. The New York Times reports on Rice University and Hewlett-Packard researchers who have developed 5 nanometer logic devices.
Read more ....These chips store only 1,000 bits of data, but if the new technology fulfills the promise its inventors see, single chips that store as much as today’s highest capacity disk drives could be possible in five years. The new method involves filaments as thin as five nanometers in width — thinner than what the industry hopes to achieve by the end of the decade using standard techniques. The initial discovery was made by Jun Yao, a graduate researcher at Rice. Mr. Yao said he stumbled on the switch by accident.
How To Make Money Developing Mobile Apps
From Tod.fm:
Do you want to make money developing applications for iPhones, iPads, and other mobile devices? I went from almost zero experience to earning a regular income from my apps in a few short months. Let me show you how I did it.
This is a long article (6,217 words). I will go through some important aspects of writing successful apps, from finding and choosing the right ideas to develop, to a very important money saving tip. Although I’m writing from the perspective of an iOS developer, the general ideas apply to other platforms like Android. Whether you develop for Apple’s devices or not, you can still benefit from the article.

My Comment: A rather long article, but an interesting read.
This Is Weird
Dating-Simulation Game a Last Resort For Honeymoon Town and Its Lonely Guests.
ATAMI, Japan—This resort town, once popular with honeymooners, is turning to a new breed of romance seekers—virtual sweethearts.
Since the marriage rate among Japan's shrinking population is falling and with many of the country's remaining lovebirds heading for Hawaii or Australia's Gold Coast, Atami had to do something. It is trying to attract single men—and their handheld devices.

What Is Consciousness?
From Think Big:
What does it mean to be conscious? It's a question that philosophers and scientists have puzzled over perhaps since there have been philosophers and scientists.
In his book "Consciousness Explained," Tufts University philosopher Daniel Dennett calls human consciousness "just about the last surviving mystery," explaining that a mystery is something that people don't yet know how to think about. "We do not yet have all the answers to any of the questions of cosmology and particle physics, molecular genetics and evolutionary theory, but we do know how to think about them," writes Dennett. "With consciousness, however, we are still in a terrible muddle. Consciousness stands alone today as a topic that often leaves even the most sophisticated thinkers tongue-tied and confused. And, as with all of the earlier mysteries, there are many who insist—and hope—that there will never be a demystification of consciousness."

Second Super-Fast Flip Of Earth's Poles Found
From The New Scientist:
SOME 16 million years ago, north became south in a matter of years. Such fast flips are impossible, according to models of the Earth's core, but this is now the second time that evidence has been found.
The magnetic poles swap every 300,000 years, a process that normally takes up to 5000 years. In 1995 an ancient lava flow with an unusual magnetic pattern was discovered in Oregon. It suggested that the field at the time was moving by 6 degrees a day - at least 10,000 times faster than usual. "Not many people believed it," says Scott Bogue of Occidental College in Los Angeles.

They Crawl, They Bite, They Baffle Scientists
From The New York Times:
Don’t be too quick to dismiss the common bedbug as merely a pestiferous six-legged blood-sucker.
Think of it, rather, as Cimex lectularius, international arthropod of mystery.
In comparison to other insects that bite man, or even only walk across man’s food, nibble man’s crops or bite man’s farm animals, very little is known about the creature whose Latin name means — go figure — “bug of the bed.” Only a handful of entomologists specialize in it, and until recently it has been low on the government’s research agenda because it does not transmit disease. Most study grants come from the pesticide industry and ask only one question: What kills it?

What Created This Smooth, 200-Mile-Long Trench On Mars?
From Popular Science:
The European Space Agency has released a series of new images of Orcus Patera, a long crater near Mars's Mons Olympus whose rim rises some 6,000 feet. But the images, taken by the Mars Express craft, only deepen the mystery of the crater's origin.
The ESA says "the most likely explanation is that it was made in an oblique impact, when a small body struck the surface at a very shallow angle." Sounds almost definitely like aliens.

How the 105-mph Fastball Tests The Limits Of The Human Body
From Popular Mechanics:
A Triple-A pitcher shocked the baseball world with a pitch clocked at an insanely fast 105 mph. Here's why we won't see pitchers throw it much faster than this—ever.
Last Friday was a mixed bag for fans of the fastball. Early in the day, the Washington Nationals announced that phenom Stephen Strasburg, who hurled a 101-mph pitch in his debut in June, would likely require Tommy John surgery for his injured elbow; a procedure that could sideline him for up to 18 months. But later that night Aroldis Chapman, a 22-year-old Cuban defector pitching for the Cincinnati Reds' triple-A affiliate in Louisville, captured baseball fans' attention when he threw a pitch clocked at 105 mph.
