Mammograms cause breast cancer, groundbreaking new research declares

Ever since the U.S. Preventive Services Task Force took a look, finally, at the scientific evidence and announced new recommendations earlier this month for routine mammograms -- specifically that women under 50 should avoid them and women over 50 should only get them every other year -- the reactions from many women, doctors and the mainstream media have reached the point of near hysteria. Not getting annual mammograms, some say, means countless women will receive a virtual death sentence because their breast tumors won't be discovered. But what is rarely discussed about mammograms is this: the tests could actually be causing many cases of breast cancer.

In fact, a new study just presented at the annual meeting of the Radiological Society of North America (RSNA), concludes the low-dose radiation from annual mammography screening significantly increases breast cancer risk in women with a genetic or familial predisposition to breast cancer. This is particularly worrisome because women who are at high risk for breast cancer are regularly pushed to start mammograms at a younger age -- as early as 25 -- and that means they are exposed to more radiation from mammography earlier and for more years than women who don't have breast cancer in their family trees.

Men's Genes "May Limit Lifespan"

Men carry the seeds of their own destruction in the genes present in their sperm, research suggests.

Scientists working on mice have highlighted a specific gene that, although carried by both sexes, appears to be active only in males.

They believe it allows males to grow bigger bodies - but at the expense of their longevity.

The study, by Tokyo University of Agriculture, appears in the journal Human Reproduction.

Although the study was conducted on mice, the researchers believe it could apply to all mammals - including humans.

They studied mice created with genetic material from two mothers, but no father.

This was achieved by manipulating DNA in mouse eggs so the genes behaved like those in sperm.

New Discoveries About the Experience of Anger

Younger people, those with children and less-educated individuals are more likely to experience anger, according to new UofT research that examines one of the most common negative emotions in society.

Drawing upon national survey data of more than 1,000 Americans aged 18 and older, Professor Scott Schieman from the Sociology Department at the University of Toronto has published new findings about the experience of anger.

In a chapter in the forthcoming International Handbook of Anger, to be released in January 2010, Schieman documents the basic social patterns and contexts of anger.

Flashback Best of the Web: CBS reporter blows the lid off Swine Flu media hype

In case you didn't realize it, Sharyl Attkisson is the investigative reporter behind the groundbreaking CBS News study that found H1N1 flu cases are NOT as prevalent as feared.

In fact, they're barely on the radar screen.

How did this startling information come about, and why is the U.S. Centers for Disease Control and Prevention (CDC) painting a different picture entirely? I spoke directly with Sharyl Attkisson to find out.

Two Videos

The first video is an amazing interview I did with Sharyl about ten days ago and what the bulk of this article is based on.

The second video is brand new and was done at noon yesterday in which I was videoed in the CBS studio in downtown Chicago. Sharyl was gracious enough to invite me to be on with Dr. Bernadine Healy, the former director of the NIH. We both were in agreement about the swine flu and opposed to the stance the CDC is taking, but we had different views on mammograms.

Please also watch the second interview as it is very entertaining.

Stroke and Heart Disease Trigger Revealed

Scientists have identified the trigger that leads to the arteries becoming damaged in the disease atherosclerosis, which causes heart attacks and strokes, in research published in the journal Circulation. The authors of the study, from Imperial College London, say their findings suggest that the condition could potentially be treated by blocking the molecule that triggers the damage. The research also suggests that bacteria may be playing a part in the disease.

In atherosclerosis, 'plaques' form in arteries that feed the brain and heart, obstructing the blood flow. The plaques are made of substances like fatty deposits and cholesterol. Immune cells are attracted into these plaques, which form inside the wall of the artery, leading to the artery becoming inflamed and to the artery wall being damaged. Sometimes, the plaque can burst as a result of this damage, causing a stroke or a heart attack.

This research, which was funded by the British Heart Foundation and the European Commission, reveals the trigger that leads to the inflammation and damage to the artery wall. The researchers hope they can block this trigger in order to prevent damage to the artery and, ultimately, heart attacks and strokes.

New Light Shed on Epilepsy

Pioneering research using human brain tissue removed from people suffering from epilepsy has opened the door to new treatments for the disease.

Scientists at Newcastle University have for the first time been able to record spontaneous epileptic activity in brain tissue that has been removed from patients undergoing neurosurgery.

Led by Newcastle University's Dr Mark Cunningham, the research has revealed that a particular type of brain wave pattern associated with epilepsy is caused by electrical connections between nerve cells in the brain -- rather than chemical ones. This means the traditional drugs are useless to them.

Published in the Proceedings of the National Academy of Sciences (PNAS), Dr Cunningham said the findings marked a huge step forward in our understanding of a disease which affects an estimated 45 million people worldwide.

Loneliness is Contagious, Study Suggests

People who feel isolated may spread mistrust of social connections

Staying socially connected may be just as important for public health as washing your hands and covering your cough. A new study suggests that feelings of loneliness can spread through social networks like the common cold.

"People on the edge of the network spread their loneliness to others and then cut their ties," says Nicholas Christakis of Harvard Medical School in Boston, a coauthor of the new study in the December Journal of Personality and Social Psychology. "It's like the edge of a sweater: You start pulling at it and it unravels the network."

This study is the latest in a series that Christakis and James Fowler of the University of California, San Diego have conducted to see how habits and feelings move through social networks. Their earlier studies suggested that obesity, smoking and happiness are contagious.

The new study, led by John Cacioppo of the University of Chicago, found that loneliness is catching as well, possibly because lonely people don't trust their connections and foster that mistrust in others.

Tiny Magnetic Discs Could Kill Cancer Cells: Study

Paris - Tiny magnetic discs just a millionth of a metre in diameter could be used to used to kill cancer cells, according to a study published on Sunday.

Laboratory tests found the so-called "nanodiscs", around 60 billionths of a metre thick, could be used to disrupt the membranes of cancer cells, causing them to self-destruct.

The discs are made from an iron-nickel alloy, which move when subjected to a magnetic field, damaging the cancer cells, the report published in Nature Materials said.

One of the study's authors, Elena Rozhlova of Argonne National Laboratory in the United States, said subjecting the discs to a low magnetic field for around ten minutes was enough to destroy 90 percent of cancer cells in tests.

Congressional Speeches Written by Big Pharma Lobbyists

The New York Times recently unveiled a story about industry lobbyists and the power they have over the United States Congress.

Examination of a series of statements made by 42 Congressmen revealed that Genentech, the world's largest biotechnology company, has been ghostwriting industry-favorable speech content for Congressmen to recite during health care reform oratory.

Twenty-two Republicans and 20 Democrats were found to have included some or all of Genentech's pro-biotechnology rhetoric during various speeches. Hearers began to notice identical, word-for-word statements being made by various Congressmen, all of which was traced back to Washington lobbyists hired by Genentech.

It was discovered that Genentech contrived two versions of its talking points, one for Republicans and one for Democrats. The company approached Congress and urged them to make supporting statements about biotechnology for inclusion into the Congressional Record. All statements were designed in support of the health care reform bill and its provisions for bolstering the biotechnology industry.

Two-Thirds of Chicken Tested Harbor Dangerous Bacteria

Consumer Reports' latest test of fresh, whole broilers bought in 22 states reveals that two-thirds of birds tested harbored salmonella and/or campylobacter, the leading bacterial causes of food-borne disease. The report reveals that organic "air-chilled" broilers were among the cleanest and that Perdue was found to be the cleanest of the brand-name chicken. Tyson and Foster Farms chickens were found to be the most contaminated. The report is available, free online (note, you have to click through the side bars to the left of the story) and in the January 2010 issue of the magazine.

Consumer Reports has been measuring contamination in store-bought chickens since 1998. The recent test shows a modest improvement since January 2007, when the magazine found these pathogens in 8 of 10 broilers, but the numbers are still far too high. The findings suggest that most companies' safeguards are inadequate. Consumer Reports also found that most disease-causing bacteria sampled from the contaminated chicken were resistant to at least one antibiotic, potentially making any resulting illness more difficult to treat.
