INDICATES TEEN MARIJUANA USE DOES NOT PREDICT DRUG, ALCOHOL ABUSE,
Marijuana is not a "gateway" drug that predicts or eventually leads to substance abuse, suggests a 12-year University of Pittsburgh study. The study, which found that young men who chose to initiate their drug use with marijuana were no more likely to go on to abuse drugs or alcohol than those who smoked or drank first, calls into question the long-held belief that has shaped prevention efforts and governmental policy for six decades.

Fish consumption advice - simple and straight forward:
There are several fish that are high in omega-3s and low in pollutants. These include anchovies, Atlantic mackerel and herring, farmed oysters, sardines, and wild coho, sockeye and pink salmon.
Fish consumption - the latest research
complex and circuitous:
Yahoo News Article
Adding further weight to the theory that fish may be brain food, new research found that people with diets rich in fish have a significantly lower risk of dementia and. The key appears to be docosahexaenoic acid (DHA), an omega-3 polyunsaturated fatty acid that appears to affect dementia risk and to be important for the proper functioning of the central nervous system.
"If you have a high level
of DHA, a fatty acid found in fish, it reduced your risk of dementia by
about half," and also improves memory. So, either eat more fish or
use one or two fish oil capsules a day. "...if it is the fat, you
could take fish oil supplements and avoid mercury contamination

"...patients should take enough oral cholecalciferol (never ergocalciferol, which is not vitamin D and appears to be a weaker agonist of the vitamin D receptor) in the winter to maintain high average summertime vitamin D blood levels (50 – 60 ng/ml). This means that many people with chronically low 25(OH)D levels, such as people with highly pigmented skin, the aged, the obese, and those who avoid sunlight, may need to take 5,000 IU (125 ug) of cholecalciferol daily during the colder months. How much is needed in sunnier months depends on latitude, season, weather patterns, and sunning habits." John Cannell, MD
My personal experience is that taking two 2000 IU/day has led to zero colds for the consumption period (as of Jan 4, 2007 four months).

The FDA is allowing silicone breast implants to be sold again, 14 years after they were removed from the market by the same agency over questions of safety.

Oh yea, this junk science also frightened many women, caused needless surgeries to remove the implants, and killed a few women. But who cares about that when you can destroy a company and get rich.

Blueprinting the human brain
A 3D computer simulation of 10,000 neurons firing in the human brain
produces a terabyte of data - a fraction of what it would take to map the
brain's billions of neurons in algorithms, according to scientists working
on the Blue Brain project, a collaboration of IBM, the Ecole Polytechnique
Federale de Lausanne (EPFL), in Lausanne, Switzerland, and others. The
project is an attempt to create a blueprint of the human brain to advance
cognition research. Last year, EPFL bought an IBM Blue Gene/L
supercomputer for the two-year project, which is being conducted in
Switzerland. The group only recently simulated the firing of 10,000
neurons in a single column in the neocortex, the largest area of the human
brain governing high-level thinking and action. A column typically
contains 100,000 neurons. To deal with the enormous amount of data
generated from the project, the group relies on visualisation tools to
locate and earmark interesting results in the computations for further
research. Blue Brain bought a supercomputer from SGI to create a small
media centre to display the 3D simulations, which Henry Markram, a
scientist working on the Blue Brain project, said is like sitting inside

Bluetooth mobile phone or other device to control or communicate with
their creations. Releasing the source code will make children more
familiar with the open source phenomenon, according to Raven Zachary, a
senior analyst at The 451 Group. "I suspect that the outcome will be
a vibrant community of developers, possibly including my own kids,"
he wrote on a company blog.

Stretch your Stretching
First, Pretend You're Gumby . . .
Use your mind to help your muscles go from stiff to supple the next time you're doing a full-body stretch.
Put another way: pretend you're Gumby. Researchers have found that people who vividly imagine lengthening and moving their arms or legs find stretching easier to do. And that could lead to greater flexibility gains. So close your eyes and envision your muscles getting longer and looser whenever you stretch.
In a recent study, three groups of volunteers (30 people in all) went through a 4-week flexibility program. While all the groups emerged with more limber bodies, two of them applied their minds as well as their bodies to the process. One group visualized moving the limb they were stretching, while the other imagined the physiological process of stretching, trying to "see" their muscles elongating. Both of these groups found their flexibility workouts easier to do than the members of the control group did . . . yet they still got at least the same flexibility gains. Sweet.

THE LOGIC OF LIFE, April 20
Even though the entire human genome has now been 'read' - the chemical composition of our DNA has been more or less mapped out, gene by gene - we still have a rather poor grasp of how living cells actually work.
That's because the genome is not really a 'book of life', but is just a
catalogue of the parts of the cellular machinery, rather like a list of
all the electronic components in a complicated computer circuit. The
key challenge for biologists in the twenty-first century is to figure
out how those component genes are wired together. To do that, they may need help from physicists, electronic and computer scientists, and others.

"It requires some effort to achieve a happy outlook on life, and most people don't make it." —Author and researcher Gregg Easterbrook
Psychologists have recently handed the keys to happiness to the public, but many people cling to gloomy ways out of habit, experts say. Polls show Americans are no happier today than they were 50 years ago despite significant increases in prosperity, decreases in crime, cleaner air, larger living quarters and a better overall quality of life. Happiness is 50 percent genetic, says University of Minnesota researcher David Lykken. What you do with the other half of the challenge depends largely on determination, psychologists agree. As Abraham Lincoln once said, "Most people are as happy as they make up their minds to be."
Happiness does not come via prescription drugs, although 10 percent of women 18 and older and 4 percent of men take antidepressants, according to the. Anti-depressants benefit those with mental illness but are no happiness guarantee, researchers say.
Nor will money or prosperity buy happiness for many of us. Money that lifts people out of poverty increases happiness, but after that, the better paychecks stop paying off sense-of-well-being dividends, research shows.
One route to more happiness is called "flow," an engrossing state that comes during creative or playful activity, psychologist Mihaly Csikszentmihalyi has found. Athletes, musicians, writers, gamers, and religious adherents know the feeling. It comes less from what you're doing than from how you do it.
Sonja Lyubomirsky of the University of California at Riverside has discovered that the road toward a more satisfying and meaningful life involves a recipe repeated in schools, churches and synagogues. Make lists of things for which you're grateful in your life, practice random acts of kindness, forgive your enemies, notice life's small pleasures, take care of your health, practice positive thinking, and invest time and energy into friendships and family.
The happiest people have strong friendships, says Ed Diener, a psychologist University of Illinois. Interestingly his research finds that most people are slightly to moderately happy, not unhappy.
"There are selfish reasons to behave in altruistic ways," says Gregg Easterbrook, author of "The Progress Paradox: How Life Gets Better While People Feel Worse" (Random House, 2004). "Research shows that people who are grateful, optimistic and forgiving have better experiences with their lives, more happiness, fewer strokes, and higher incomes," according to Easterbrook. "If it makes world a better place at same time, this is a real bonus." Diener has collected specific details on this. People who positively evaluate their well-being on average have stronger immune systems, are better citizens at work, earn more income, have better marriages, are more sociable, and cope better with difficulties.
Lethargy holds many people back from doing the things that lead to happiness. Easterbrook, also a Visiting Fellow at the Brookings Institute, goes back to Freud, who theorized that unhappiness is a default condition because it takes less effort to be unhappy than to be happy.
"If you are looking for something to complain about, you are absolutely certain to find it," Easterbrook told LiveScience. "It requires some effort to achieve a happy outlook on life, and most people don't make it. Most people take the path of least resistance. Far too many people today don't make the steps to make their life more fulfilling one."

The findings appear in the September issue of the Journal of Experimental Psychology: General.
The researchers found that even as cognitive skills declined, the study subjects retained higher levels of skills in the same areas they had before. For example, participants who were better at quick thinking than verbal skills at age 72 retained that gap at age 83.
The findings suggest that aging doesn't reduce brain power to a single level, Anstey says: "Our results suggest that the picture is much more complex."
