ScienceDaily (Nov. 4, 2010) - Positive psychological changes that occur during meditation training are associated with greater telomerase activity, according to researchers at the University of California, Davis, and the University of California, San Francisco. The study is the first to link positive well-being to higher telomerase, an enzyme important for the long-term health of cells in the body.

A virus was recently shown to cause a rare type of human cancer, Merkel cell carcinoma. Does it also cause a more common type of cancer?

Racing against other companies around the globe, International Battery isn the front lines of an effort to build smaller, lighter, more powerful batteries that could help transform the American energy economy by replacing gasoline in cars and making windmills and solar cells easier to integrate into the power grid.

"A new study has found that the amount of vitamin D in patients being treated for diffuse large B-cell lymphoma was strongly associated with cancer progression and overall survival. The results will be presented at the annual meeting of the American Society of Hematology in New Orleans."

Hydrogen is in many ways an ideal fuel. It possesses a high energy content per unit mass when compared to petroleum, and it can be used to run a fuel cell, which in turn can be used to power a very clean engine.

Cells within a tumour potentially not acting independantly, but more like an integrated organism.

You could be sitting alone and still be completely outnumbered for your body is home to trillions upon trillions of tiny passengers - bacteria. Your body is made up of around ten trillion cells, but you harbour a hundred trillion bacteria. For every gene in your genome, there are 100 bacterial ones. This is your 'microbiome' and it has a huge impact on your health, your ability to digest food and more. We, in turn, affect them. Everything from the food we eat to the way we're born influences the species of bacteria that take up residence in our bodies.This slideshow is a tour through this "universe of us".

Chiu now suspects that ALS is initiated by some still unknown agent or event. Then, as nerve cells begin to sicken and die, the nervous system tries to right itself by making microglia behave like wound-healers, secreting IGF-1 and other factors in an attempt to preserve motor neurons. "If the immune system has evolved in a way to help heal motor neurons," Chiu says.

What is cancer? Everyone knows that it is a terrifying disease and has some ideas about a mass of cells that grow uncontrollably but I get the feeling that many people don't quite understand how it actually happens.

Telomeres are necessary for several reasons, among them to act as 'padding' during cell duplication. Every time a linear DNA molecule is replicated it loses a few base pairs from the ends (the reason why is quite interesting,

A protein that normally helps defend cells from infection can play a critical role in the development of lung cancer, according to MIT cancer biologists. Their findings suggest that the protein, NF-κB, could be a promising target for new drugs against lung cancer, which kills more than one million people each year.

Mahendra Kumar Trivedi has proven the Trivedi Effect® to be of scientific significance through positive results. The results of the tests were also vouched by eminent scientists and scholars with in depth knowledge in molecular science. During the tests it was proven that when cancer cells bought in contact with the Trivedi Effect® their potency was drastically reduced thus improving the life expectancy and health progress of affected patients.

Drury, a geneticist, is a pioneer in new research exploring the biological impacts of early adversity on children. She is the first scientist to show that extreme stress in infancy can biologically age a child by shortening the tips of chromosomes, known as telomeres. These caps keep chromosomes from shrinking when cells replicate. Shorter telomeres are linked to higher risks for heart disease, cognitive decline, diabetes and mental illness in adults.

Brain tumor and brain cancer are synonymous terms. Due to the formation of abnormal cells in the human brain this disease occurs. Human beings below the age of 40 years, especially the kids are the most affected ones by this particular sort of cancer.

Different organs are affected by cancer cells due to different reasons and show different symptoms. Like the cause and symptoms, the healing for cancer also differs from case to case depending upon the organ affected and the severity of the case.
