Parked cars separate this Montreal cycle track from cars - and, researchers hope, from their tailpipe fumes.
Well this is a bummer: A Belgian study finds that bicyclists on urban streets inhale tens of millions of toxic nanoparticles with each breath, taking in five times as much as drivers and pedestrians on the same streets.

The U.K. Times reports on the new research:
Because they are exerting themselves, cyclists breathe harder and faster than other road users. The study found that they suck in about 1,000 cubic cm with each breath, meaning they may inhale tens of millions of the particles each time they fill their lungs, and billions during a whole journey.

"This is the first time anyone has counted the particles while also measuring people's breathing during city commuting. It showed that cyclists can inhale an astonishing number of pollutant particles in one journey," said Luc Int Panis of the transport research institute at Hasselt University in Belgium, who led the study.

Most people are familiar with type-1 diabetes and type-2 diabetes, but did you know researchers have discovered a third type of diabetes? Type-3 diabetes, as they are calling it, affects people who are extra sensitive to electrical devices that emit "dirty" electricity.

Type-3 diabetics actually experience spikes in blood sugar and an increased heart rate when exposed to electrical pollution ("electropollution") from things like computers, televisions, cordless and mobile phones, and even compact fluorescent light bulbs.

Dr. Magda Havas, a PhD from Trent University in Canada, recently published the results of a study she conducted on the relationship between electromagnetic fields and diabetes in Electromagnetic Biology and Medicine. In it, she explains how she and her team came to discover this about why electropollution is so dangerous for many people.

Antidepressants Dramatically Raise Risk of Cataracts

Of the 35 million Americans who are age 65 or older, the National Institutes of Health (NIH) claims about 7 million of them suffer from clinical depression -- and millions are on the prescription antidepressant drugs known as selective serotonin reuptake inhibitors (SSRIs) such as Prozac, Paxil, Lexapro and Zoloft. Hyped by Big Pharma as the way to solve depression problems in all age groups, these medications come with a litany of serious side effects, including some that are particularly dangerous for elders.

For example, a University of Minnesota study found SSRIs increase the rate of bone loss in older men and women. And now there's even more reason for seniors to be wary of taking SSRIs. New research just published in Ophthalmology, the journal of the American Academy of Ophthalmology, concludes taking these antidepressants substantially raises the risk of sight-threatening cataracts.

A cataract is a clouding of the lens in the eye that affects vision. In fact, as cataracts progress, they can cause enough deterioration of eyesight that surgery is needed to remove them. Although cataracts are common in older people, there are many factors that can increase a person's risk of actually developing the eye problem, including exposure to cigarette smoke, air pollution, and heavy alcohol consumption. And now you can add taking SSRIs to that list.

Osteoporotic bone showing areas that have lost mass
Recent research from Scotland reinforces the longstanding medical opinion that vitamin D deficiency leads to a significantly increased risk of bone fractures.

Among people with hip fractures referred to the Scottish fracture liaison service, 98 percent test positive for serious deficiencies in vitamin D. Supplementation with the vitamin, on the other hand, significantly reduces the risk of repeat fractures.

"Taking a supplement can make a difference quite quickly," said Stephen Gallacher, head of the liaison service. "Bone density can increase by 20 percent in a few months with enough vitamin D."

"We have found we can reduce fractures by something like 30 to 50 percent. It is our belief that we can significantly reduce the risk of fractures in the population by giving people anti-osteoporosis therapy and vitamin D supplements."

Sleep Problems Are Common in US Soldiers Returning from Wartime Deployment


Science Daily
Wed, 09 Jun 2010 19:24 UTC
There is an extremely high prevalence of sleep disturbances in U.S. soldiers returning from wartime deployment, according to a research abstract presented June 8, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.

Results indicate that 86 percent of participants had sleep disturbances upon return from deployment and 45 days later even though the majority of them had no signs of post-traumatic stress disorder or depression. Soldiers were more likely to have sleep disturbances if they had a personal history of sleep problems, symptoms of physical illness or mild traumatic brain injury.

Sleep Deprivation Linked to Depression in Teens

The rate of depression among the students was very high in the study of high schoolers and sleep.
Sleep-deprived high school students who doze off in class aren't just risking the wrath of their teachers. They're also three times more likely to be depressed than their alert classmates who get enough sleep, a new study has found.

"Sleep deprivation and depression go hand in hand among teenagers," says the study's lead author, Mahmood Siddique, D.O., a sleep medicine specialist at the Robert Wood Johnson Medical School, in New Brunswick, New Jersey.
"Instead of giving them medications, I'd rather give them a chance to sleep better, and more."
Daytime sleepiness appears to be the new normal for adolescents. More than half of the 262 high school seniors who participated in the study were "excessively sleepy," according to a commonly used scale that gauges how likely a person is to doze off during everyday activities such as reading, watching TV, or sitting in a traffic jam.

Speaking out against Dairy

The government sure is milking that moustache gag. They've promoted dairy so much that the phrase 'Got Milk' is now a national catch phrase. But why are they promoting milk so hard? And is it really the building block of health? The answers will shock you.

The United States Department of Agriculture (USDA) recommends three glasses of milk a day. Why? Because milk will build strong bones and combats osteoporosis. Well that's what the government tells us. But I'm telling you that milk breaks bones and may even be linked to cancer. And I've got significant studies, leading research, and Harvard University experts to prove it.

Pyramid Power

Milk is considered one of nature's great building blocks. That's because it's enjoyed great promotion for many years. Much of that promotion comes from the USDA Food Guide Pyramid. But several of the "experts" who 'built' the pyramid are dairy industry insiders. The pyramid protects industry interests, not what's best for your health. That's according to Dr. Mark Hyman. Hyman practices family medicine in Lenox, Mass. He's also on the Board of Advisors and faculty of Georgetown University School of Medicine's Food as Medicine training program.

Comment: Casein, the protein in dairy, has the potential to evoke an autoimmune response and/or mimic endorphins to cause changes in perception, mood, and behavior; but it is to say that milk can cause you problems in other ways as well. For more information see Why Milk Is So Evil.

An expert said young people using Facebook found it harder to relate
Youths hooked on social networking sites are struggling to relate, a leading neuroscientist says.

Baroness Susan Greenfield says more research is needed to establish a possible link between Facebook and a lack of empathy among the young.

"If you are not rehearsing looking someone in the eye in three dimensions, but instead you have 900 friends on Facebook ... one does question what kind of relationship they might be having," she told the National Press Club in Canberra.

"We are being complacent in the extreme if you just dismiss me as a whingeing, middle-aged Luddite."

The Professor of Pharmacology at Oxford University in the UK was more positive about the virtues of an ageing brain.

Study Shows How Radiation Causes Breast Cancer

It's well-established that exposure to ionizing radiation can trigger mutations and other genetic damage and cause normal cells to become malignant. So it seems amazing how mainstream medicine frequently dismisses the idea that medical imaging tests from mammograms to CT scans could play much of a role in causing breast cancer. Take this example from the web site for Cornell University's Program on Breast Cancer and Environmental Risk Factors:

In answer to the question "Is ionizing radiation a cause of breast cancer?", the Cornell experts say "Yes" and note ".. female breast tissue is highly susceptible to radiation effects." But then they pooh-pooh the possible hazard from mammography x-rays saying the risk ..."should not be a factor in individual decisions to undergo this procedure. The same is true for most diagnostic x-ray procedures."

If that's not confusing enough, they turn around and state: "Nonetheless, unnecessary radiation exposures should be avoided and continued vigilance is required to ensure that the benefits associated with specific procedures outweigh the future risks."

How Your Brain Works on Autopilot

Anyone who's learned to ride a bike or touch type might have wondered how a task that is so arduous at first could be so seamlessly easy later. A new study reveals more about exactly what goes on in the brain as we form these habits, transitioning from intense concentration to autopilot.

The results, found in rats but thought to be analogous to humans, show that habitual learning, as it's called, involves two brain circuits - one used for movement and the other for higher, cognitive thinking.

As a task is learned, these circuits trade off in terms of their engagement. The movement circuit, which involves a part of the brain called the dorsolateral striatum, becomes more active, while the cognitive circuit, which involves a region called the dorsomedial striatum, takes a dip.
