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.

4 Big Losers From Apple's TV, iPod Announcement
From Popular Mechanics:
At today's music-themed keynote in San Francisco, Apple rolled out a lot of goodies as fanboys cheered each announcement. It was hard not to imagine entire industries turning red with fear. Apple is a powerful company, and their business decisions and product announcements have a tendency to radically reshape entire industries. Let's look at some of the biggest potential losers from today's announcements.

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.

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.

Health Checkup: Who Needs Organic Food?
Organic food comes with real health benefits and significant costs. TIME looks at both sides of the debate
From Time Magazine:
Looking for a quick way to feel lousy about yourself? Then forget the idea of a healthy diet and just eat what your body wants you to eat. Your body wants meat; your body wants fat; your body wants salt and sugar. Your body will put up with fruits and vegetables if it must, but only after all the meat, fat, salt and sugar are gone. And as for the question of where your food comes from — whether it's locally grown, sustainably raised, grass-fed, free range or pesticide-free? Your body doesn't give a hoot.

Yet Another Human Job Is Replaced By A Robot
Yet another human job is replaced by a robot.
BIG crowds, strong surf and powerful rip currents are only a few of the obstacles that lifeguards must overcome to keep swimmers safe. Strong winds can pull many bathers out to sea simultaneously, overwhelming the guards if there are only a few of them. And, since average swimming speed is about 3kph (2mph) even a single rescue mission can take more than half an hour.

Water in Earth's Mantle Key To Survival Of Oldest Continents
From Science Daily:
ScienceDaily (Sep. 2, 2010) — Earth today is one of the most active planets in the Solar System, and was probably even more so during the early stages of its life. Thanks to the plate tectonics that continue to shape our planet's surface, remnants of crust from Earth's formative years are rare, but not impossible to find. A paper published in Nature Sept. 2 examines how some ancient rocks have resisted being recycled into Earth's convecting interior.

High-Tech Effort Underway to Protect Magna Carta
From Live Science:
The Magna Carta helped form the foundation for modern English and U.S. law. Now one of two copies known to exist outside England is headed for a special new case to preserve it.
The very first Magna Carta dates to 1215, when English barons forced King John to write down the traditional rights and liberties of the country's free persons. A copy of the Magna Carta signed by King Edward I in 1297 currently resides within a helium-filled casement at the National Archives Building in Washington. But the medieval document is scheduled for a temporary removal in 2011 so it can be re-measured for a new case filled with argon.

Why Do Heavy Drinkers Outlive Nondrinkers?
From Time Magazine:
One of the most contentious issues in the vast literature about alcohol consumption has been the consistent finding that those who don't drink tend to die sooner than those who do. The standard Alcoholics Anonymous explanation for this finding is that many of those who show up as abstainers in such research are actually former hard-core drunks who had already incurred health problems associated with drinking.

My Comment: I am convinced .... and yes .... I need a drink.
One Reason Dieting Does Not Work
One reason dieting does not work.
IF, BY chance, you are served an unusually large slice of pizza, compared with what others appear to be getting, would that experience incline you, some minutes later, to eat more cookies or fewer when platefuls came your way? That depends, it turns out, on whether you are on a diet. Those who are not eat fewer cookies, whereas those who are see the excessive pizza as a licence to pig out. It is a demonstration of what Janet Polivy, a psychologist at the University of Toronto, refers to as the “what the hell” effect—a phenomenon familiar from real life to which Dr Polivy has given scientific respectability, most recently in a paper published in the latest edition of Appetite.

Why Food Is Costing Us The Earth
From The Telegraph:
The fight is on over how to solve our food crisis, but if we choose the wrong food policy at this juncture there could be no going back, says Rose Prince.
Hardly a morning passes without food making the headlines. This week has brought us the burger that thinks it's a pizza and news that eating asparagus makes you stay slim (fingers crossed it's the type covered in melted butter). And we heard that, if you eat pickled squid guts and single cream together, it tastes like strawberry shortcake.

Samsung Galaxy Tab: Firm Joins Forces With Google By Launching Tablet to Take On Apple's iPad
From The Daily Mail:
Apple faces a killer blow to its iPad after Samsung unveiled its own device amid rumours it could could be just half the price.
The Samsung Galaxy Tab with its seven inch touchscreen is smaller than the iPad, however it matches the Apple device in virtually all other functions.
Initial details suggest some aspects of the Tablet are even more sophisticated than the Apple creation.
At the same time, Apple faces competition from other technology giants which are racing to get their own touchscreen tablets into the shops before Christmas.

Stephen Hawking Says There's No Theory Of Everything
From New Scientist:
Craig Callender, contributor
Three decades ago, Stephen Hawking famously declared that a "theory of everything" was on the horizon, with a 50 per cent chance of its completion by 2000. Now it is 2010, and Hawking has given up. But it is not his fault, he says: there may not be a final theory to discover after all. No matter; he can explain the riddles of existence without it.

Global Energy Use In The 21st Century
From Watts Up With That?:
Guest Post by Thomas Fuller
This is a great time to talk about energy use worldwide. Not because it’s topical, or politically important, or anything like that. It’s a great time because the math is easier now than ever before, and easier than it ever will be again.
It’s similar to a time a few years ago when there were almost exactly 100 million households in the United States. It made a lot of calculations really easy to do. And this year, the United States Department of Energy calculates that the world used 500 quads of energy. Ah, the symmetry.

DARPA's Cyber Insider Threat Program Is The Agency's Great Hope For Ending Leaks
From Popular Science:
The recent WikiLeaks exposure was a huge black eye for the U.S. Department of Defense, supposedly one of the more secure state organizations we have working for us. Its impact clearly wasn’t lost on the Pentagon, whose blue sky research arm has launched a new project designed to ferret out malicious behavior on DoD networks. Named CINDER – Cyber INsiDER Threat – the project is designed not to sniff out people, but adversarial actions as they happen.

Why Older People Repeat Stories
There may be a reason grandparents repeat the same stories over and over again. According to a new study, older people are more likely than younger people to forget with whom they've shared information.
The study investigated two types of memory: source memory, or your recollection of who told you a piece of information; and destination memory, which is your recollection of which people you've informed. Not only were older people bad at remembering to whom they'd told information, they were very confident in their mistaken memories. [10 Ways to Keep Your Mind Sharp]

NASA Planning Mission To Visit The Sun
From The CBS:
We know it's hot up there but NASA wants to know a bit more about the Sun and its environs. And so sometime before 2018, the agency intends to send a spacecraft into the solar atmosphere.
This will mark the first time that a spacecraft from earth will actually visit a star.
The decision to chart a mission to the Sun also realizes a dream that astronomers almost realized a half century ago, when the National Academy of Science's "Simpson Committee" in 1958 recommended a probe to investigate. Several studies were subsequently carried out testing the feasibility of the project. But nothing came of them.

Robotic Storm Tracker Gets A Big Test With Earl
From Technology Review:
The largest-ever storm monitoring mission is now gathering scientific data that was previously impossible to get.
As Hurricane Earl barrels toward the eastern seaboard of the United States, coastal residents don't know if they should evacuate in case the storm makes landfall. They rely on forecasters analyzing computer models, but those predictions differ. A new hurricane-monitoring mission that's now underway hopes to reduce this uncertainty by gathering atmospheric and environmental storm data never before obtained.

When Drones Go Wild
An advanced fly-by-wire system capable of landing grossly damaged unmanned aircraft—demonstrated on video saving a plane missing 80 percent of one wing—is key to solving one of unmanned flight’s biggest problems.
Word spread last week that a rogue MQ-8B Fire Scout copter drone entered restricted airspace just 40 miles shy of Washington D.C. after losing contact with its operators. The revelation occurred smack in the middle of AVUSI 2010, the world’s largest UAV tradeshow. And it served as a poignant reminder that all the game-changing technology on display here at the Denver Convention Center still has some innovating to do, especially when flight crews lose control of their unmanned craft.

Shape-Shifting Robot Compensates For Damaged Limb
From New Scientist:
Think that shape-shifting robots, or ones that march on no matter how many limbs they lose, are just for Terminator films? Think again. A team of European roboticists have developed software that allows a modular robot to adapt when one part stops working.
David Johan Christensen at the University of Southern Denmark in Odense, working with Alexander Spröwitz and Auke Ijspeert at the Swiss Federal Institute of Technology in Lausanne, simulated a quadruped robot constructed from a dozen Roombots – identical rounded robots that have been developed in Lausanne and which can combine to form a variety of modular shapes (see picture).
