Children Who Get Spanked Have Lower IQs
From Live Science:
Spanking can get kids to behave in a hurry, but new research suggests it can do more harm than good to their noggins. The study, involving hundreds of U.S. children, showed the more a child was spanked the lower his or her IQ compared with others.
"All parents want smart children," said study researcher Murray Straus of the University of New Hampshire. "This research shows that avoiding spanking and correcting misbehavior in other ways can help that happen."

Photon 'Machine Gun' Could Power Quantum Computers
From New Scientist:
THERE is a simple rule of computing that holds true even in the weird quantum world: increase the number of units of information available and you boost computing power. Raising the number of quantum bits, or qubits, carries an even greater reward – every additional qubit doubles the computing power.
But raising the number of qubits has proven tricky because of the difficulty of reliably producing entangled particles. Now a team has designed a system that should fire out barrages of entangled photons with machine-gun regularity.

The Tech Behind Surrogates's All-Robot World
From Popular Mechanics:
PM's Digital Hollywood sits down with Surrogates director Jonathan Mostow to discuss the unexpected challenges of filming a world where everyone looks like a perfect robot. Plus, a chronology of movie androids.
When robot stand-ins populate the world in a movie—as they do in Touchstone Picture’s Surrogates, out Sept. 25—every character in the frame has to look perfect. And that turned into a headache for director Jonathan Mostow. “Usually you hire background actors off the street,” he says. “We were flying in models.”

Self-Regulated Morphine Delivery For Wounded Warfighters
own morphine without watchful medics U.S. Army
From Popular Science:
DARPA-funded nanotech drug automatically regulates its morphine dose on the battlefield
Medics still use morphine to relieve the pain of wounded soldiers on the modern battlefield, but have to watch out for morphine reducing breathing and blood pressure to dangerous levels. That may all change with a DARPA-backed combination drug that has successfully limited morphine delivery when it detects low blood oxygen levels.

Mars Probe Watches Water-Ice Fade
From The BBC:
Large deposits of nearly pure water-ice may lurk just below the Martian surface, much nearer the equator than previously thought, suggest new images.
The pictures acquired by a Nasa orbiter show white material exposed by fresh meteorite impacts fading over time - behaviour expected of ice on Mars.
An onboard instrument also detected the tell-tale chemical signature of water.

Satellite Images Of The Second Iranian Nuclear Site
Satellite imagery company GeoEye has released a photo of what it says is the controversial and underground Iranian uranium enrichment site that came to light last week.
The photo, taken Saturday, shows the facility at a military site about 20 miles north-northeast of Qum and 100 miles southwest of Tehran, GeoEye said. An analysis of the photo by IHS Jane's, a defense intelligence consulting firm, said the facility has a primary and several auxiliary entrances, ventilation shafts, a surface-to-air missile site, and quarry and construction equipment.

My Comment: The imaging is very clear. We also must give them credit for making it public as quickly as they did.
UK Warned As Plague Of Bee-Eating Hornets Spreads North In France
From The Guardian:
For five years they have wreaked havoc in the fields of south-western France, scaring locals with their venomous stings and ravaging the bee population to feed their rapacious appetites. Now, according to French beekeepers, Asian predatory hornets have been sighted in Paris for the first time, raising the prospect of a nationwide invasion which entomologists fear could eventually reach Britain.

Fresh Doubts Over Hitler's Death After Tests On Bullet Hole Skull Reveal It Belonged To A Woman
From The Daily Mail:
Adolf Hitler may not have shot himself dead and perhaps did not even die in his bunker, it emerged yesterday.
A skull fragment believed for decades to be the Nazi leader’s has turned out to be that of a woman under 40 after DNA analysis.
Scientists and historians had long thought it to be conclusive proof that Hitler shot himself in the head after taking a cyanide pill on 30 April 1945 rather than face the ignominy of capture.

My Comment: I love a mystery like this one.
To Explain Longevity Gap, Look Past Health System
From New York Times:
If you’re not rich and you get sick, in which industrialized country are you likely to get the best treatment?
The conventional answer to this question has been: anywhere but the United States. With its many uninsured citizens and its relatively low life expectancy, the United States has been relegated to the bottom of international health scorecards.
But a prominent researcher, Samuel H. Preston, has taken a closer look at the growing body of international data, and he finds no evidence that America’s health care system is to blame for the longevity gap between it and other industrialized countries. In fact, he concludes, the American system in many ways provides superior treatment even when uninsured Americans are included in the analysis.

The Challenge Of Making Real 'Surrogate' Skin
From Live Science:
The new movie "Surrogates," starring Bruce Willis, depicts a world in which people live through "surries", highly realistic humanoid robots. But without realistic skin, robots will never have that humanlike personal touch, and will not have the degree of social acceptance that robots would need to have to share the world with the rest of us.
A recent paper details research into this area. In "Towards Humanlike Social Touch for Sociable Robotics," John Cabibihan and his fellow scientists detailed the reasons for testing and developing realistic skin for social robots.

Population: Overconsumption Is The Real Problem -- A Commentary
From The New Scientist:
THERE is a pervading myth that efforts to fight climate change and other environmental perils will be to no avail unless we "do something" about population growth. Even seasoned analysts talk about the threat of "exponential" population growth. But there is no exponential growth. In most of the world fertility rates are falling fast, and the countries where population growth continues are those that contribute least to our planetary predicament.

Population: Technology Will Save Us -- A Commentary
From New Scientist:
Throughout history, technological innovation has saved us from being overwhelmed by overpopulation, and Jesse Ausubel tells Alison George why he is convinced that human resourcefulness can pull the fat out of the fire even now
You're known as a techno-optimist. Why have you got such faith in technology's power to save the environment?
I regard myself as neither an optimist nor a pessimist. But I do think that humanity is ingenious and enterprising. Throughout the ages people have doubted that their descendants could exist, with improving health and longevity, in the numbers and densities we do now. In the 19th century it was common to reason that horse manure or chimney smoke would bury or choke cities. Yet air quality in New York City and water quality in New York harbour are better than when I or my mother was a child. Over time people find, invent and spread solutions for many environmental problems.

Population: Enough Of Us Now -- A Commentary
From New Scientist:
GLOBAL population growth has slowed significantly, but it hasn't stopped. By 2050 there may be about 35 per cent more people on Earth than there are today. We are already seeing increasing shortages of food, water and other resources and growing numbers of hungry people.
Yet to embark on any discussion about limiting our numbers is to enter sensitive and controversial territory. Perhaps this is not surprising, as in the 1960s, when population growth became an issue of widespread concern, the discussions often had a racist undertone, in which the "well-off" focused on the exploding populations of "underdeveloped nations".

4 People Who Faced Disaster—And How They Made it Out Alive
From Popular Mechanics:
Some disasters are simply not survivable. But most are, and research on human behavior suggests that the difference between life and death often comes down to the simple—yet surprisingly difficult—task of recognizing threats before they overwhelm you, then working through them as discrete challenges. The people who survive disasters tend to be better prepared and more capable of making smart decisions under pressure. Not everyone is born with these traits, but almost anyone can learn them. Here’s how to wire your brain for survival.

Augmented Google Earth Gets Real-Time People, Cars, Clouds
From Popular Science:
Researchers from Georgia Tech have devised methods to take real-time, real-world information and layer it onto Google Earth, adding dynamic information to the previously sterile Googlescape.
They use live video feeds (sometimes from many angles) to find the position and motion of various objects, which they then combine with behavioral simulations to produce real-time animations for Google Earth or Microsoft Virtual Earth.

What Happens To A Hoard Of Old Gold?
From BBC News Magazine:
The Staffordshire hoard of Anglo-Saxon gold is being described as the most significant find in many years, but just what happens next?
Long queues are snaking around the block at a Birmingham museum where the items are now on view. But after the initial excitement dies down, what exactly will happen to the hundreds of pieces?
While much of the mud has been brushed off the 1,381 items, a proper investigation into the find will have to wait until a series of important procedures are completed.

The 10 Most Outrageous Military Experiments
From Live Science:
A super soldier program produces Marvel superhero Wolverine in the movie "X-Men Origins: Wolverine," along with rivals Sabretooth and Weapon XI. Now Live Science looks back on real experiments that the U.S. government ran on soldiers and citizens to advance the science of war.
The military didn't replicate Wolverine's indestructible skeleton and retractable claws. Rather, they shot accident victims up with plutonium, tested nerve gas on sailors, and tried out ESP. While some of the tests seem outlandish in hindsight, the military continues to push the envelope in seeking new warfare techniques based on cutting-edge science and technology.

Real Science Sets Up Surrogates‘ Futuristic Robot Action
From Underwire:
HOLLYWOOD — Taken at face value, Bruce Willis’ new sci-fi thriller Surrogates sports a premise every bit as outlandish as the wig he wears during much of the movie. In the film’s near-future setting, humans have withdrawn from everyday life almost completely. Instead, they hole up in their homes and send robotic versions of themselves, called “surrogates,” into the real world.
The remote-control androids, which look vaguely like the robots from 1973’s Westworld, perform the operators’ jobs and interact with other surrogates. Willis stars as both a fresh-faced surrogate and its worn-out operator, who chafes at the lack of personal interaction in his life.
