Pomegranate juice helps keep fatty deposits from collecting on artery walls

A study in the current issue of the Proceedings of the National Academy of Sciences, by Italian and American scientists reports that pomegranate juice helped keep fatty deposits from collecting on artery walls in mice, and kept human heart cells healthier. The mice were specially bred to have high cholesterol and on human heart cells in culture.

Molecule called DJ-1 is likely to be involved in the generation of human tumors

Scientists have discovered that a molecule called DJ-1 is likely to be involved in the generation of human tumors through negative regulation of the well-known tumor suppressor, PTEN. The research, published in the March issue of Cancer Cell, has important implications for determining the prognosis of some human cancers, and may prove to be a suitable target for cancer therapy.

Cells can regenerate without becoming "younger"

It has long been thought that cells that regenerate tissue do so by regressing to a developmentally younger state. Now two University of Washington researchers have demonstrated that cells can regenerate without becoming "younger."

Early Alzheimer's disease may be precipitated by a neuron traffic jam

Early Alzheimer's disease may be precipitated by a “traffic jam” within neurons that causes swelling and prevents proper transport of proteins and structures in the cells, according to new studies by Howard Hughes Medical Institute researchers.

Protein called CK2 plays a deadly role in colorectal carcinoma

A protein called CK2 plays a deadly role in colorectal carcinoma by blocking the ability of these tumors to activate a natural self-destruct mechanism that would clear this cancer from the body. This finding, by researchers at St. Jude Children's Research Hospital, is currently published in the online edition of Oncogene.

Researchers identify target for cancer drugs

For nearly a decade, scientists have been trying to fully understand a particular communication pathway inside of cells that contributes to many malignant brain and prostate cancers. While scientists have identified elements of this pathway, other key components have remained a mystery.

Visual recognition begins with categorization

Take a moment and look at a picture near you. What did you see? How long did it take you to understand what was in the image, meaning how long did it take you to realize the green blob was a tree? Or that the orange circle was a piece of fruit? Most likely you assume that it took you no time at all, you just knew.
