Darryl Jones faces court over cancer cure claims | Herald Sun
A QUEENSLAND man who claims he can cure cancer with diet and exercise is facing court action questioning the credibility of his treatment regime.
The Australian Competition and Consumer Commission (ACCC) alleges Darryl Peter Jones' medical treatment claims are misleading or deceptive under the Trade Practices Act.
Before it was shut down, the Darryl Jones Health Resolution Centre's website, advertised a cancer treatment program involving an exercise regimen, the consumption of vitamin B17 and restriction of glucose in the diet.

Too many narcotics prescribed after surgery: study | Reuters
Too many narcotics prescribed after surgery: study | Reuters
Many people who undergo urology procedures may be sent home with more narcotic painkillers than they need -- leaving home medicine cabinets filled with the potentially addictive drugs, a new study suggests.
Researchers found that of 213 patients prescribed narcotic painkillers after surgery for a urological condition, two-thirds had leftover pills a few weeks later. And most -- 91 percent -- were keeping those leftovers in their medicine cabinets.
That's a problem, the researchers say, because those pills can be abused by anyone with access to the medicine cabinet.

Graphene and 'spintronics' combo looks promising
Graphene and 'spintronics' combo looks promising
A team of physicists has taken a big step toward the development of useful graphene spintronic devices. The physicists, from the City University of Hong Kong and the University of Science and Technology of China, present their findings in the American Institute of Physics' Applied Physics Letters.
Graphene, a two-dimensional crystalline form of carbon, is being touted as a sort of "Holy Grail" of materials. It boasts properties such as a breaking strength 200 times greater than steel and, of great interest to the semiconductor and data storage industries, electric currents that can blaze through it 100 times faster than in silicon.
Spintronic devices are being hotly pursued because they promise to be smaller, more versatile, and much faster than today's electronics. "Spin" is a quantum mechanical property that arises when a particle's intrinsic rotational momentum creates a tiny magnetic field. And spin has a direction, either "up" or "down." The direction can encode data in the 0s and 1s of the binary system, with the key here being that spin-based data storage doesn't disappear when the electric current stops.

Men more likely to stick with girlfriends who sleep with other women than other men
Men are more than twice as likely to continue dating a girlfriend who has cheated on them with another woman than one who has cheated with another man, according to new research from a University of Texas at Austin psychologist.
Women show the opposite pattern. They are more likely to continue dating a man who has had a heterosexual affair than one who has had a homosexual affair.

Physics for financial markets
Physics for financial markets
As a result of the financial crisis, many countries are trying to regulate their financial markets. Recently the heated debates about bonus taxes, a permanent levy on banks' balance sheets and a ban on short sales have taken another turn, with France's President Nicolas Sarkozy promoting a transaction tax. But are policy-makers doing the right thing? Or will they obstruct the self-regulating forces of the markets?
The use of two fundamental mechanisms from physics, friction and noise, could provide a solution. These mechanisms can be viewed as setting boundaries to the system's self-organization, rather than impeding it.

A mix of tiny gold and viral particles, and the DNA ties that bind them
A mix of tiny gold and viral particles, and the DNA ties that bind them
Scientists have created a diamond-like lattice composed of gold nanoparticles and viral particles, woven together and held in place by strands of DNA. The structure -- a distinctive mix of hard, metallic nanoparticles and organic viral pieces known as capsids, linked by the very stuff of life, DNA -- marks a remarkable step in scientists' ability to combine an assortment of materials to create infinitesimal devices.
When scientists mixed the particles, out of the brew emerged a sodium thallium crystal lattice. The device "self assembled" or literally built itself.
The research adds some welcome flexibility to the toolkit that scientists have available to create nano-sized devices.

Marriage is good for physical and mental health, study finds
The 'smug marrieds' may have good reason to feel pleased with themselves as experts now confirm that long-term committed relationships are good for mental and physical health and this benefit increases over time.
In an editorial published by student BMJ, David and John Gallacher from Cardiff University say that on average married people live longer. They say that women in committed relationships have better mental health, while men in committed relationships have better physical health, and they conclude that "on balance it probably is worth making the effort."

Could Food Choices Be a Factor in the Shooting of a US Congresswoman?
Could Food Choices Be a Factor in the Shooting of a US Congresswoman?
The U.S. is still reeling from another tragedy -- the attempted assassination of Congresswoman Gabrielle Giffords, and the murder of several civilians during the attempt.
Many are asking what the cause might have been -- whether it was pervasive, over-the-top violent rhetoric in the culture, or simply mental psychosis.
But, even if the former, there is still the underlying cause of mental psychosis to consider.
And what if people are lashing out with such destructive force, at Columbine, Virginia Tech, and now Arizona, not because of what they are hearing, but at least in part because of what they are eating?

Saturated, Trans Fat in Food May Increase Risk of Depression, Study Finds - Bloomberg
People who eat more trans fats from cheese, milk or processed foods may have a 48 percent increased risk of depression, compared with those who consume almost no trans fats, a study from Spain showed.
Olive oil, by contrast, appeared to have a slight protective effect against the mental illness among 12,059 Spanish participants in the research, according to a report in the journal PLoS One.
The study is the first to analyze the effects of dietary fat on depression, the authors wrote. Research has already linked trans fats, which are created through a process that adds hydrogen to oil, to increased heart risk.

Chemists turn gold to purple -- on purpose: Color change confirms a new way to harvest energy from sunlight
Professor Richard Watt and his chemistry students suspected that a common protein could potentially react with sunlight and harvest its energy -- similar to what chlorophyll does during photosynthesis.
The story of how they proved it sounds as colorful as the legend of the leprechaun who hid his pot of gold at the end of the rainbow.
They started with citric acid from oranges and mixed it with the protein. Next they dissolved gold powder into the solution. Then they put vials of the yellow-colored mixture in direct sunlight and crossed their fingers in the hope that it would turn purple.

Gender and hygiene: Could cleanliness be hurting girls?
Little girls growing up in western society are expected to be neat and tidy -- "all ribbon and curls" -- and one researcher who studies science and gender differences thinks that emphasis may contribute to higher rates of certain diseases in adult women.
The link between increased hygiene and sanitation and higher rates of asthma, allergies and autoimmune disorders is known as the "hygiene hypothesis" and the link is well-documented. Yet the role of gender is rarely explored as part of this phenomenon.

Ancient body clock discovered that helps keep all living things on time
The mechanism that controls the internal 24-hour clock of all forms of life from human cells to algae has been identified by scientists.
Not only does the research provide important insight into health-related problems linked to individuals with disrupted clocks -- such as pilots and shift workers -- it also indicates that the 24-hour circadian clock found in human cells is the same as that found in algae and dates back millions of years to early life on Earth.

Breast implants may be linked to rare cancer: FDA | Reuters
Women with breast implants may face an increased risk of a rare immune-system cancer near their implants, U.S. regulators said on Wednesday.
Health officials need more data to tell if the implants are related to the cancer and are asking doctors to report any confirmed cases, the Food and Drug Administration said in a statement. Overall the agency still considers implants safe.
The cancer warning could hit sales of silicone-gel and saline implants sold by Allergan Inc and Johnson & Johnson's Mentor unit. Allergan shares fell more than 2 percent.

Scientists Discover How To Store Data In Bacteria
Scientists Discover How To Store Data In Bacteria
Researchers at Hong Kong's Chinese University have found what might be the safest way to store data: not in a safe, not in the cloud, but in bacteria.
Biostorage, the term for storing and encrypting information in organisms, has only existed for close to a decade, but scientists say the method could soon allow for text, images, music, or even video to be "recorded" in E. Coli, according to Discovery.
By encoding data in bacterial DNA, the information has a virtually limitless lifespan. As each bacteria reproduces, the data could be copied thousands of times. By mapping E. Coli's DNA, that data can be easily found and isolated.
Perhaps more importantly however, bacteria isn't susceptible to intrusion.
"Bacteria can't be hacked," Allen Yu, a student instructor, told Discovery.

BBC News - 'Life chemicals' may have formed around far-flung star
There is now even more evidence that life on Earth may have been seeded by material from asteroids or comets.
Prior research has shown how amino acids - the building blocks of life - could form elsewhere in the cosmos.
These molecules can form in two versions, but life on Earth exclusively uses just one of them.
Now an Astrophysical Journal Letters paper shows how conditions around a far-flung star could favour the formation of one type over another.
Amino acids are corkscrew-shaped molecules that can form twisted to the left or right, and chemistry does not inherently favour one corkscrew direction over another. But without exception, life on Earth makes use of the left-handed version.

Practical full-spectrum solar cell comes closer
Practical full-spectrum solar cell comes closer
Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps). Different colors have different energies, and no single semiconductor has a band gap that can respond to sunlight's full range, from low-energy infrared through visible light to high-energy ultraviolet.
Although full-spectrum solar cells have been made, none yet have been suitable for manufacture at a consumer-friendly price. Now Wladek Walukiewicz, who leads the Solar Energy Materials Research Group in the Materials Sciences Division (MSD) at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), and his colleagues have demonstrated a solar cell that not only responds to virtually the entire solar spectrum, it can also readily be made using one of the semiconductor industry's most common manufacturing techniques.

A workplace's key employees may be at the greatest risk of experiencing high levels of work stress, according to a new study by the Centre for Addiction and Mental Health (CAMH).
In a survey of 2,737 workers, 18 per cent reported that their job was "highly stressful."
The odds of having high stress were greater if workers were managers or professionals, if they thought their poor job performance could negatively affect others, or if they worked long or variable hours. The study was published in this month's International Journal of Occupational and Environmental Medicine.

New math theories reveal the nature of numbers
New math theories reveal the nature of numbers
For centuries, some of the greatest names in math have tried to make sense of partition numbers, the basis for adding and counting. Many mathematicians added major pieces to the puzzle, but all of them fell short of a full theory to explain partitions. Instead, their work raised more questions about this fundamental area of math.
Ono and his research team have discovered that partition numbers behave like fractals. They have unlocked the divisibility properties of partitions, and developed a mathematical theory for "seeing" their infinitely repeating superstructure. And they have devised the first finite formula to calculate the partitions of any number.

Scientists close to new definition of the kilogram - Technology & science
Scientists say they are close to achieving a 200-year-old goal of creating a universal system of measurements based on stable quantities, as they progress toward changing how the kilogram is defined.
The kilogram is the only base unit in the International System of Units (SI) that is still defined by a physical object — a prototype of platinum-iridium kept in the vaults of the International Bureau of Measurements (BIPM) in France.
The stability of the kilogram is crucial as it forms the basis from which many other units are derived.

Scientists from the RIKEN Brain Science Institute in Japan said that intuitive playing was probably not due to nature, but brain training.

Couples who struggle to conceive could find baby-making help from antioxidants such as vitamin E and zinc, hints a new review of more than 30 studies.
The researchers focused on men who were subfertile — less fertile than average but still capable of making a baby — and found that those who took antioxidants were more than four times as likely to get their partners pregnant than subfertile men who did not take the supplements.

Childhood Last Name Predicts Whether You Buy Early, Late: Study - Yahoo! News
The first letter of your childhood surname may influence your consumer behavior as an adult, according to a new study.
U.S. researchers examined how fast adults responded to opportunities to buy items they wanted, and they found that those with childhood last names that began with a letter that appeared later in the alphabet tended to be the quickest purchasers.
However, this effect wasn't seen with surnames that had changed because of marriage.

Distance may be key in successful negotiations, new study shows
Adding physical distance between people during negotiations may lead to more mutually beneficial outcomes, according to new research from The University of Texas at Austin.
"People tend to concentrate on higher priority items when there is more distance between them by looking at issues in a more abstract way," says Henderson. "They go beyond just thinking about their pursuit of the options presented to them and consider higher-level motives driving their priorities."

Why first impressions are so persistent
Why first impressions are so persistent
New research by a team of psychologists from Canada, Belgium, and the United States shows there is more than a literal truth to the saying that 'you never get a second chance to make a first impression'. The findings suggest that new experiences that contradict a first impression become 'bound' to the context in which they were made. As a result, the new experiences influence people's reactions only in that particular context, whereas first impressions still dominate in other contexts.

From Hollywood studios to Japanese TV makers, powerful business interests are betting 3-D will be the future of entertainment, despite a major drawback: It makes millions of people uncomfortable or sick.
Optometrists say as many as one in four viewers have problems watching 3-D movies and TV, either because 3-D causes tiresome eyestrain or because the viewer has problems perceiving depth in real life. In the worst cases, 3-D makes people queasy, leaves them dizzy or gives them headaches.

Nanoparticles in Sewage Sludge May End Up in the Food Chain | Wired Science | Wired.com
Plants and microbes can absorb nano-sized synthetic particles that magnify in concentration within predators up the food chain, according to two new studies.
Nanoparticles can be made of countless different materials, and their safety isn’t well-understood. Yet the minuscule specks are infused into hundreds of consumer products ranging from transparent suncreens to odor-eating socks.
From there, they can wash down drains, ultimately ending up in the sewage sludge of wastewater treatment plants. About 3 million tons of dried-out sludge is subsequently mixed into agricultural soil each year.
“We wanted to look into the possibility of nanoparticles getting into the food chain in this way,” said environmental toxicologist Paul Bertsch of the University of Kentucky. “What we found really surprised us.”

Scott Brusaw, a 53-year-old electrical engineer in tiny Sagle, Idaho, thinks he has a solution. So far, he's generated interest from the federal government and General Electric in his idea for a solar-powered roadway made from super-strong glass, instead of conventional asphalt or concrete.

Let's be honest, a kiss is never just a kiss. It is the ultimate romantic symbol in our culture -- from Shakespearean tragedies to Gustav Klimt's gilded embrace to the legendary V-J Day smooch in Times Square to those critical words "you may kiss the bride." Sometimes it's instead an expression of affection, elation, loyalty or, on the other hand, disloyalty (see: the kiss of Judas). In cruder manifestations -- take Britney and Madonna's lip smacking, and the tonsil hockey of modern reality television -- it's a way to scandalize. But despite this breadth of meaning, we have very rigid ideas of what types of kissing are appropriate and acceptable -- as Stephanie Seymour recently discovered after photos circulated of an ocean-side embrace with her son.

Any dreadlocked white guys finding this article after Googling "Drugs Rule" should know that we've given this list about drugs a rule. To make the cut, an accomplishment has to be considered great by people who could pass a field sobriety test. So no Grateful Dead music. We're sure someone somewhere has enjoyed the Dead perfectly sober, just as there are probably non-Christians who listen to Christian Rock. But we're just as sure that in the grand scheme of things, those people don't count.
In fact, because we're masochists, we gave ourselves a strict no music policy, leaving us with ... well, not a whole lot actually. Turns out most great things were accomplished by people who just said no, at least immediately prior to accomplishing them. Except for these five.

Men have upper hand in sexual economy – The Chart - CNN.com Blogs
It's not a new theory: As women progress in educational and professional opportunities, their odds of finding a committed man appear to go down. Women in their 40s and 50s have long heard this, but new research finds it's true for women just entering adulthood as well.
Researchers found that since women in the 18- to 23-year-old group feel they don't need men for financial dependence, many of them feel they can play around with multiple partners without consequence, and that the early 20s isn't the time to have a serious relationship. But eventually, they do come to want a real, lasting relationship. The problem is that there will still be women who will have sex readily without commitment, and since men know this, fewer of them are willing to go steady.

A new study suggests that when it comes to certain genes, friends of a feather flock together—but with others, opposites attract. The research offers potential insight into subtle genetic influences that may affect how people become friends—which can have an enormous impact on later life choices. One gene that may link friends, for example, is also connected to the risk of alcoholism.
“We live in a sea of genes,” says lead author James Fowler, professor of medical genetics and political science at the University of California-San Diego. “What happens to us may not depend only on our genes but on the genes of our friends.” (More on Time.com: Do Friends Make Your Amygdala Larger?)

New Type Of Entanglement Allows 'Teleportation in Time,' Say Physicists - Technology Review
Entanglement is the strange quantum phenomenon in which two or more particles become so deeply linked that they share the same existence.
That leads to some counterintuitive effects, in particular, when two entangled particles become widely separated. When that happens, a measurement on one immediately influences the other, regardless of the distance between them. This "spooky-action-at-a-distance" has profound implications about the nature of reality but a clear understanding of it still eludes physicists.
Today, they have something else to puzzle over. Jay Olson and Timothy Ralph at the University of Queensland in Australia say they've discovered a new type of entanglement that extends, not through space, but through time.

Here's a health tip in a nutshell: Eating a handful of nuts a day for a year — along with a Mediterranean diet rich in fruit, vegetables and fish — may help undo a collection of risk factors for heart disease.
Spanish researchers found that adding nuts worked better than boosting the olive oil in a typical Mediterranean diet. Both regimens cut the heart risks known as metabolic syndrome in more people than a low-fat diet did.

Family, friends, social ties influence weight status in young adults
Does obesity tend to "cluster" among young adults? And if so, what impact does it have on both their weight and weight-related behaviors? That's what researchers from The Miriam Hospital's Weight Control and Diabetes Research Center set out to answer to better understand how social influences affect both weight status and weight loss intentions in this difficult-to-reach age group.
According to the study, published online by the journal Obesity, overweight and obese young adults between the ages of 18 and 25 were more likely to have overweight romantic partners and best friends and also had more overweight casual friends and family members compared to normal weight peers. Also, overweight and obese young adults who reported having social contacts trying to lose weight had greater weight loss intentions.

Engineers give solar power a boost
Engineers give solar power a boost
The growing popularity of solar photovoltaic (PV) systems across the United States has made it more important to maximize their power input. That's why UC San Diego environmental engineering professor Jan Kleissl is working on technologies and methods that will better predict how much power we can actually harness from the sun.
"Probably the most important result of this work for California is that in all coastal areas (Los Angeles, San Francisco, San Diego) it is advantageous to install the panels facing about 10-degrees west of south," Kleissl said. "This not only optimizes energy production, but it also improves the correlation of solar power production with the load. Panels facing southwest 'see' the sun longer and at a better angle than panels facing south, which means that the energy generated is larger during the peak demand hours (3-to-5p.m.), making the energy more valuable. The generally clear conditions during the annual load peaks (also known as Santa Anas to Southern Californians) mean that the solar panels produce at the optimum power.

Gravitational lensing: Cosmic magnifying lenses distort view of distant galaxies
Gravitational lensing: Cosmic magnifying lenses distort view of distant galaxies
Looking deep into space, and literally peering back in time, is like experiencing the universe in a house of mirrors where everything is distorted through a phenomenon called gravitational lensing. Gravitational lensing occurs when light from a distant object is distorted by a massive object that is in the foreground. Astronomers have started to apply this concept in a new way to determine the number of very distant galaxies and to measure dark matter in the universe.
Albert Einstein showed that gravity will cause light to bend. The effect is normally extremely small, but when light passes close to a very massive object such as a massive galaxy, a galaxy cluster, or a supermassive black hole, the bending of the light rays becomes more easily noticeable.

Marketing efforts that encourage mixing caffeinated "energy" drinks with alcohol often try to sway young people to believe that caffeine will offset the sedating effects of alcohol and increase alertness and stamina.
"There appears to be little or no protective benefit from the addition of caffeine to alcohol, with respect to the safe execution of activities that require sustained attention with rapid, accurate decisions," says the study, published in the February edition of the journal Addiction.

When most people in the developed world think of measles, what comes to mind is only a dim memory of a vaccination at a pediatrician's office. But while childhood vaccination has virtually eliminated measles from North America and much of Europe, researchers remain interested in the virus.
This fascination persists partly because improving the measles vaccine could help eliminate the more than 10 million measles infections and 150,000 measles-caused deaths that still occur worldwide. But it also has another source: Scientists believe that modified measles viruses can be "re-targeted" to attack only tumor cells, and thus transformed into a powerful new therapy for cancer.

Light can control electrical properties of graphene
Light can control electrical properties of graphene
New research published January 10, shows how light can be used to control the electrical properties of graphene, paving the way for graphene-based optoelectronic devices and highly sensitive sensors.
Graphene is an extraordinary two-dimensional material made of a single atomic layer of carbon atoms. It is the thinnest material known to man, and yet is one of the strongest ever tested.
Graphene does not have volume, only surface -- its entire structure is exposed to its environment, and responds to any molecule that touches it. This makes it in principle a very exciting material for super-sensors capable of detecting single molecules of toxic gases. Polymers can make graphene respond to specific molecules and ignore all others at the same time, which also protects it from contamination.

No left turn: 'Superstreet' traffic design improves travel time, safety
No left turn: 'Superstreet' traffic design improves travel time, safety
The so-called "superstreet" traffic design results in significantly faster travel times, and leads to a drastic reduction in automobile collisions and injuries, according to North Carolina State University researchers who have conducted the largest-ever study of superstreets and their impacts.
Superstreets are surface roads, not freeways. It is defined as a thoroughfare where the left-hand turns from side streets are re-routed, as is traffic from side streets that needs to cross the thoroughfare. In both instances, drivers are first required to make a right turn and then make a U-turn around a broad median. While this may seem time-consuming, the study shows that it actually results in a significant time savings since drivers are not stuck waiting to make left-hand turns or for traffic from cross-streets to go across the thoroughfare.

Parents give boys preferential treatment when there is a chronic food shortage
Parents give boys preferential treatment when there is a chronic food shortage
In situations of chronic food shortage, parents are inclined to give boys a preferential treatment, despite the fact that the health of their daughters suffers more from food insecurity. This is shown by research from the Institute of Tropical Medicine in Ethiopia, appearing in the journal Pediatrics.
It is self-evident that food shortages are not healthy, but up to now nobody hat looked if all children in a family suffer equally, or if there are gender differences. In most studies into the effects of food insecurity, parents were questioned, not their children. Scientists of Jimma University (Ethiopia), assisted by American and Flemish scientists, during five years followed two thousand teenagers in as many households, in urban as well as rural communities

Pot Shrinks Tumors; Government Knew in '74 | Drugs | AlterNet
In 1974 researchers learned that THC, the active chemical in marijuana, shrank or destroyed brain tumors in test mice. But the DEA quickly shut down the study and destroyed its results, which were never replicated -- until now.
The term medical marijuana took on dramatic new meaning in February, 2000 when researchers in Madrid announced they had destroyed incurable brain tumors in rats by injecting them with THC, the active ingredient in cannabis.
The Madrid study marks only the second time that THC has been administered to tumor-bearing animals; the first was a Virginia investigation 26 years ago. In both studies, the THC shrank or destroyed tumors in a majority of the test subjects.
Most Americans don't know anything about the Madrid discovery. Virtually no major U.S. newspapers carried the story, which ran only once on the AP and UPI news wires, on Feb. 29, 2000.

Top Ten Legal Drugs Linked to Violence – TIME Healthland
When people consider the connections between drugs and violence, what typically comes to mind are illegal drugs like crack cocaine. However, certain medications — most notably, some antidepressants like Prozac — have also been linked to increase risk for violent, even homicidal behavior.
A new study from the Institute for Safe Medication Practices published in the journal PloS One and based on data from the FDA's Adverse Event Reporting System has identified 31 drugs that are disproportionately linked with reports of violent behavior towards others.

Optimism Could Help Kids Keep Depression at Bay - Yahoo! News
Here's a reason to try to change your kid's attitude: The most optimistic adolescents may be somewhat less likely to be depressed than their peers.
Researchers also have found a slight link between optimism and less heavy drug abuse and bad behavior.
There are caveats. The new research, on kids in Australia, doesn't prove that optimism directly causes kids to be less depressed. Other factors could explain things. The study also suggests that the most optimistic kids were not able to avoid having as many bad things happen in their lives as more pessimistic kids.
"Optimistic kids do better in avoiding emotional and behavioral problems during the teens, but it in no way makes them immune to setbacks," said the study's lead author, Dr. George C. Patton, of Australia's Royal Children's Hospital in Melbourne. "There are a whole lot of other skills and experiences that are also important in getting through life."

Energy limits global economic growth, study finds
Energy limits global economic growth, study finds
A study that relates global energy use to economic growth, published in the January issue of BioScience, finds strong correlations between these two measures both among countries and within countries over time.
The research leads the study's authors to infer that energy use limits economic activity directly. They conclude that an "enormous" increase in energy supply will be required to meet the demands of projected world population growth and lift the developing world out of poverty without jeopardizing standards of living in most developed countries.

Abstinence, heavy drinking, binge drinking associated with increased risk of cognitive impairment
Abstinence, heavy drinking, binge drinking associated with increased risk of cognitive impairment
Previous research regarding the association between alcohol consumption and dementia or cognitive impairment in later life suggests that mild to moderate alcohol consumption might be protective of dementia. However, most of the research has been conducted on subjects already rather elderly at the start of the follow-up.
The study, conducted at the University of Turku, University of Helsinki and National Institute for Health and Welfare in Finland based on subjects from the Finnish Twin Cohort, shows that midlife alcohol consumption is related to the risk of dementia assessed some 20 years later. The study indicates that both abstainers and subjects consuming large amounts of alcohol have a greater risk for cognitive impairment than light drinkers.

Being poor can suppress children's genetic potentials, study finds
Growing up poor can suppress a child's genetic potential to excel cognitively even before the age of 2, according to research from psychologists at The University of Texas at Austin.
These findings go to the heart of the age-old debate about whether "nature" or "nurture" is more important to a child's development. They suggest the two work together and that the right environment can help children begin to reach their genetic potentials at a much earlier age than previously thought.

A study of antibodies from people infected with H1N1 swine flu adds proof that scientists are closing in on a "universal" flu shot that could neutralize many types of flu strains, including H1N1 swine flu and H5N1 bird flu, U.S. researchers said on Monday.
They said people who were infected in the H1N1 pandemic developed an unusual immune response, making antibodies that could protect them from all the seasonal H1N1 flu strains from the last decade, the deadly "Spanish flu" strain from 1918 and even a strain of the H5N1 avian flu

Atmosphere's self-cleaning capacity surprisingly stable
An international, NOAA-led research team took a significant step forward in understanding the atmosphere's ability to cleanse itself of air pollutants and some other gases, except carbon dioxide. The issue has been controversial for many years, with some studies suggesting the self-cleaning power of the atmosphere is fragile and sensitive to environmental changes, while others suggest greater stability. And what researchers are finding is that the atmosphere's self-cleaning capacity is rather stable.

Green Tea May Prevent Dementia, Study Says - FoxNews.com
Drinking green tea regularly could protect the brain against developing Alzheimer's. It could also protect you against other forms of dementia, a group of UK scientists claimed Thursday.
"What was really exciting about this study was that we found when green tea is digested by enzymes in the gut, the resulting chemicals are actually more effective against key triggers of Alzheimer's development than the undigested form of the tea," project leader Dr. Ed Okello said.
"In addition to this, we also found the digested compounds had anti-cancer properties, significantly slowing down the growth of the tumor cells, which we were using in our experiments."

How studded winter tires may damage public health, as well as pavement
How studded winter tires may damage public health, as well as pavement
Scientists are reporting new evidence on how studded tires -- wintertime fixtures in some areas but banned in others for causing damage to pavement -- may also damage the health of motorists and people living near highways. Studded tires have small metal protrusions from the rubber tread that improve traction on icy or snow-covered roads.
studded tires grind away at the road surface, generating the kind of dust particles believed to contribute to heart and respiratory disease when inhaled into the lungs. Studded tires are winter mainstays in Finland, Norway, Sweden and other northern countries, but have been banned or restricted in others and in some states because they damage pavement. The scientists' past research found that road dust from studded tires causes biological changes in cells related to inflammation, a process underlying heart and respiratory diseases.

In a finding that gives new meaning to the adage, "waste not, want not," scientists are reporting that household sewage has far more potential as an alternative energy source than previously thought. They say the discovery, which increases the estimated potential energy in wastewater by almost 20 percent, could spur efforts to extract methane, hydrogen and other fuels from this vast and, as yet, untapped resource.

Aspartame exposed - GM Bacteria used to create deadly sweetener
The manufacturers of the most prevalent sweetener in the world have a secret, and it`s not a sweet one. Aspartame, an artificial sweetener found in thousands of products worldwide, has been found to be created using genetically modified (GM) bacteria. What`s even more shocking is how long this information has been known. A 1999 article by The Independent was the first to expose the abominable process in which aspartame was created. Ironically, the discovery was made around the same time as rich leaders around the globe met at the G8 Summit to discuss the safety of GM foods.

Birch bark ingredient comes with many metabolic benefits
An ingredient found in abundance in birch bark appears to have an array of metabolic benefits, according to new studies in animals that are reported in the January issue of Cell Metabolism, a Cell Press publication. In mice, the compound known as betulin lowered cholesterol, helped prevent diet-induced obesity, and improved insulin sensitivity. Betulin-treated mice were also more resistant to developing atherosclerotic plaques in their arteries.

Technique turns computer chip defects into an advantage
Technique turns computer chip defects into an advantage
Physicists at Ohio State University have discovered that tiny defects inside a computer chip can be used to tune the properties of key atoms in the chip.
The technique, which they describe in the journal Science, involves rearranging the holes left by missing atoms to tune the properties of dopants -- the chemical impurities that give the semiconductors in computer chips their special properties.
