Depending on which variant of the gene CYP1A2 a woman has, a coffee consumption rate of at least two cups a day can either reduce the total risk of developing breast cancer or delay the onset of cancer, according to new research from Lund University and Malmö University in Sweden.

The effect of coffee is related to estrogens - female sex hormones. Certain metabolic products of these hormones are known to be carcinogenic and various components of coffee can alter the metabolism so that a woman acquires a better configuration of various estrogens.

Coffee, of course, contains caffeine, which also hampers the growth of cancer cells.

'Functional foods' are those that provide a health benefit beyond basic nutrition and more people are recognizing that they are an important part of a lifestyle that leads to long-term fitness and even longevity.

Liz Sloan, writing in Food Technology, has identified the top 10 trends in functional foods. The article noted that a majority of Americans, 69 percent, are incorporating foods into a preventative lifestyle, while 27 percent are utilizing food as a treatment to manage a preexisting health condition. One-third of shoppers (36 percent) are trying to reduce the risk of developing a health condition, follow a doctor’s advice (30 percent) or manage/treat a specific condition on their own (25 percent), according to the Food Marketing Institute¹ data.

“Today’s consumers are extremely sophisticated, and they are attracted to functional foods’ ability to help manage health and wellness,” said Institute of Food Technologists(IFT) spokesperson Roger Clemens, PhD. Simply put, Americans are relying heavily on the foods they consume to improve their well-being.

At Abercrombie & Fitch, little girls were sold thong underwear tagged with the phrases "eye candy" and "wink wink." In Britain, preschoolers could learn to strip with their very own Peekaboo Pole-Dancing Kits, complete with kiddie garter belts and play money. And 'tween readers of the magazine Seventeen discovered "405 ways to look hot" like Paris Hilton.

This kind of sexualization of 'tween girls - defined as those between the ages of 8 and 12 - in pop culture and advertising is a growing problem fueled by marketers' efforts to create cradle-to-grave consumers, a University of Iowa journalism professor argues in her new book.

"A lot of very sexual products are being marketed to very young kids," said Gigi Durham, author of The Lolita Effect. "I'm criticizing the unhealthy and damaging representations of girls' sexuality, and how the media present girls' sexuality in a way that's tied to their profit motives. The body ideals presented in the media are virtually impossible to attain, but girls don't always realize that, and they'll buy an awful lot of products to try to achieve those bodies. There's endless consumerism built around that."

Are you exhausted? Do you have pain all over but can’t figure out what’s wrong? If so, you may be suffering from fibromyalgia, a chronic condition that causes exhaustion, sleep disturbances and diffuse pain in your muscles, tendons, and ligaments.

Fibromyalgia patients experience a range of symptoms of varying intensities that increase and decrease over time and often resemble other conditions. For years, because of their complex nature and a lack of research on the condition, many doctors misdiagnosed fibromyalgia symptoms or dismissed them as being in the patient’s head. Even today, it is estimated to take an average of five years for a fibromyalgia patient to get an accurate diagnosis.

There is no laboratory test available to diagnose fibromyalgia. Doctors must rely on patient histories, self-reported symptoms, a physical examination and an accurate manual tender point examination.

Evolutionary trees, or "phylogenies", are a major part of modern evolutionary science. They depict hypotheses regarding the relationships among taxa, and are therefore important in reconstructions of the historical path of evolution (Gregory 2008a,b).

Various approaches can be taken to formulating phylogenetic hypotheses, including analyses based on morphological, fossil, and/or molecular data. These methods often agree well, but sometimes one or another can throw up some surprises and challenge previous hypotheses about the relationships among groups of organisms.

Reconstructing the tree of life is a difficult and complicated process, and one should expect there to be significant refinements and revisions along the way. This is especially true of the deepest branches of the tree, which are often the most difficult to resolve.

Case in point, the Tree of Life Web Project gives the following summary of deep branches among major animal lineages:

An international team of scientists has detected that some of the glow of Earth’s aurora is polarized, an unexpected state for such emissions. Measurements of this newfound polarization in the Northern Lights may provide scientists with fresh insights into the composition of Earth’s upper atmosphere, the configuration of its magnetic field, and the energies of particles from the Sun, the researchers say.

If observed on other planets, the phenomenon might also give clues to the shape of the Sun’s magnetic field as it curls around other bodies in the solar system.

When a beam of light is polarized, its electromagnetic waves share a common orientation, say, aligned vertically, or at some other angle. Until now, scientists thought that light from energized atoms and molecules in planetary upper atmospheres could not be polarized. The reason is simple: in spite of the low number of particles at the altitudes concerned (above 100 kilometers (60 miles)), there are still numerous collisions between molecules and gas atoms. Those collisions depolarize the emitted light.

At today's sessions of the 43rd Annual Meeting of the European Association for the Study of the Liver (EASL), experts reported advances in basic research that have important implications for the eventual treatment of people with chronic liver diseases.

We go back a long way with herpesviruses. Our evolutionary line has been living with these genomic parasites for more than 100 million years, and today herpesviruses infect nearly all humans, as well as all other mammals, birds and reptiles that scientists have checked. We aren't born with these viruses, but most of us acquire multiple infections of various types of herpesviruses during childhood.

Unlike our relationship with many other, more notorious viruses, we've learned to peacefully coexist with herpesviruses for the most part. They set up shop in our cells, they use our molecular machinery to replicate themselves, and they take advantage of the influx of energy we provide from our diet. Sometimes the relationship goes sour, with the unfortunate results ranging from chickenpox to mononucleosis, genital herpes, and Burkitt's lymphoma, but by and large, most humans, and mammals in general, are never seriously harmed by these house guests. But do we get anything out of this relationship? Remarkably, recent research suggests that this 100 million-year coexistence may have been good for us too, helping our immune system to ward off even more serious pathogens.

It's been just over three years since I got married, and I remember thinking (amid the nearly debilitating fear that we would run out of alcohol at our mountain cabin wedding and thus trap our families in a scene from The Shining) that it would be wonderful to finally be free forever from the intrigue and confusion of dating.

You can't fault the optimism.

Now, through the lens of hindsight, I realize that I should have known that dating and even cohabitating were only warm-ups for the big dance.
