If emotions can make you sick, if a belief that you will die can kill you (as in voodoo deaths), and if a sugar pill that you believe is a powerful drug can take away your pain, can a belief that you can bring about your own recovery help you to recover?

Even with acceptance of the role of emotional factors in both illness and recovery, the assumption has persisted that emotional factors work on an unconscious level, and because of this they are not subject to voluntary control. Most of us still see illness as something that happens to us.

Dr. Carl Simonton, chief of radiation at Travis Air Force Base, questioned this assumption. He was impressed by demonstrations that people could learn to control autonomic processes through biofeedback and ...

Having more cells usually puts one at a higher risk for cancer - but not for the elephant. Despite packing 100 times as many cells as humans, this towering animal can keep cancer at bay thanks to extra copies of a tumor-fighting gene. Researchers found that Asian elephants harbor 30 to 40 copies of the gene that encodes the protein p53, one of the most important mechanisms for preventing cancer and maintaining cell division. If cells have DNA damage that could spawn tumors, p53 prevents them from dividing until they make repairs or spurs them to commit suicide. In contrast, humans sport only two copies of the gene for p53, and so does elephants’ closest living relative, the rock hyrax. The extra copies probably accumulated millions of yea ...

When a person dies from cancer, the culprit isn't usually the original tumor - it's metastasis, the spread of cancer cells throughout the body. Now, researchers have managed to package a drug in nanoparticles (a microscopic particle with at least one dimension less than 100 nm) so that it can target these cancer cells without, crucially, interfering with normal cells - and report that they've stopped cancer cells from spreading in mice. Nanoparticle research is currently an area of intense scientific research, due to a wide variety of potential applications in biomedical, optical, and electronic fields.

A drug made from berries produced the blushwood tree (Hylandia dockrillii), found in Australia, has been used to treat animals with face and neck tumours, and it starts taking effect within five minutes. Human trials have now been approved. According to researchers, in 75 percent of the 300 animals cases, the tumour disappeared in individuals that were treated with isolated compound found in the seed, and has so far not come back. "The compound works in three ways essentially: it kills the tumour cells directly, it cuts off the blood supply and it also activates the body's own immune system to clean up the mess that's left behind." ...

A new study out of Harvard University shows that pasteurized milk products from factory farms is linked to causing hormone-dependent cancers. It turns out that the concentrated animal feeding operations model of raising cows on factory farms churns out milk with dangerously high levels of estrone sulfate, an estrogen compound linked to testicular, prostate, and breast cancers.

Dr. Ganmaa Davaasambuu, Ph.D., and her colleagues specifically identified "milk from modern dairy farms" as the culprit, referring to large-scale confinement operations where cows are milked 300 days of the year, including while they are pregnant. Compared to raw milk from her native Mongolia, which is extracted only during the first six months after cows have already ...
