Up to 40% of U.S. Bee Colonies Decimated By Mysterious Ailment
PHILADELPHIA (Reuters) - A mysterious disease is killing off U.S. honeybees, threatening to disrupt pollination of a range
of crops and costing beekeepers hundreds of thousands of
dollars, industry experts reported last month.
Beekeepers in 22 states have reported losses of up to 80% of their colonies in recent weeks, leaving many
unable to rent the bees to farmers of crops such as almonds
and, later in the year, apples and blueberries.
"It's unusual in terms of the widespread distribution and
severity," said Jerry Bromenshenk, a professor at the
University of Montana at Missoula and chief executive of Bee
Alert Technology, a company monitoring the problem.
Researchers from state and federal agricultural agencies have
been frustrated in their search for a cause because...read entire article
One Simple Thing You Can Do to Radically Lower Your Risk of Breast Cancer
Upwards of six hours of strenuous activity each week could reduce your risk of invasive breast cancer by as much as 23%. A recent survey of more than 15,000 women showed that exercise has a lifelong protective effect against invasive breast cancer.
The survey was of women between the ages of 20 and 69 living in Wisconsin, New Hampshire and Massachusetts. During structured telephone interviews, researchers questioned almost 8,000 women without breast cancer, more than 1,500 survivors of non-invasive breast cancer, and more than 6,000 survivors of invasive breast cancer.
The women were asked about their physical activity, occupation, family history of breast cancer, menopausal status, and body mass index.
A reduction in risk for women who exercised was apparent whether the physical activity took place early in life, in postmenopausal years, or in the recent past.

"Fat Makes You Fat," Right? Not Always
Some fats will increase your risk of cancer and cardiovascular disease and cause you to gain weight. But healthy fats can not only improve your cardiovascular health and reduce your risk of cancer, but can even help you lose weight.
Many processed foods and conventionally raised meats contain high levels of omega-6 fatty acids. While essential in small amounts, too much of these fats can raise your risk of disease and increase the accumulation of fat in your body. Omega-3 fatty acids –found in fatty fish, fish oil, walnuts, hemp seed, and flax seed oil–have the opposite effect.
The Journal of Nutrition published one study where rats that ate diets supplemented with DHA, one of the omega-3 fatty acids in fish oil, had a decrease in body fat mass. Other laboratory studies indicate the reasons for this result. For one thing, DHA prevents undifferentiated cells from becoming preadipocytes (precursors to fat cells). Plus, it inhibits the fat storage capacity of adipocytes (the cells that store fat).
So, not only does DHA decrease the total number of fat cells, it also...read entire article
The Health Benefits of Sex
A very credible study connecting overall health with sexual frequency comes from Queens University in Belfast. They tracked the mortality of about 1,000 middle-aged men over the course of a decade. After 10 years, the British Medical Journal revealed the men who reported the highest frequency of orgasm enjoyed a death rate 50% lower than the others.
Other studies show that having sex a few times a week has a direct link to...Read Entire Article
Skipping Sleep Harms Your Brain
Lack of sleep may cause the brain to stop producing new cells. A study on rats showed that lack of sleep caused a stress hormone to affect the hippocampus, a brain region involved in forming memories.
Rats that were deprived of sleep for 72 hours had higher levels of the stress hormone corticosterone and, as a result, produced significantly fewer new brain cells in a region of the hippocampus.
When corticosterone levels were kept at a constant level, the hippocampus produced a normal amount of new cells.
After the animals were restored to normal sleep patterns, it took two weeks for nerve cell production levels to normalize.

The Healing Power of Sunlight
If you enjoy feeling the warm rays of the sun on your skin, you already know that sunlight feels good. But you might not know that it can also be good for you.
For decades people have been told by experts and the media that the sun is harmful and should be avoided. We've been told there's no such thing as a healthy tan, and we've been warned to cover our skin, coat ourselves in chemical sunscreens and avoid exposure to direct sunlight. It turns out that this advice is not only inaccurate, it is a contributing factor to a significant amount of the disease and illness in our society.
That's because exposure to sunlight is the ideal and safest way for your body to obtain vitamin D. It's nearly impossible to get adequate amounts of this vital nutrient from your diet without supplementation. This is why sensible exposure to natural sunlight is absolutely essential for optimal health.
Tan Without Fear of Burning or Skin Damage
Based on years of modern research, our scientifically formulated tanning tablets enable your body to create more melanin, a natural pigment that your body produces to darken your skin. The more melanin you have, the less time you need in the sun and the darker your tan. Unlike some other types of tanning tablets and messy creams, Tanamins™ do not contain any dyes or artificial coloring agents. Instead, these all-natural tanning vitamins provide the exact nutrients your body needs so you can tan quickly and easily even if you're fair skinned. If you're concerned about skin damage or are short of time, Tanamins™ are for you. Two 20-minute sun exposures per week is all you’ll need. Get Tanamins™ here.
