To better understand how cells become cancerous, a new study by cancer researchers looks at four genes that help regulate cell growth in embryos and contribute to cancer in adults. The genes are generally believed to work together to help control cell proliferation. But this study shows that mice need ...

The tick-tock of your biological clock may have just gotten a little louder. The number of genes under control of the biological clock in a much-studied model organism is dramatically higher than previously reported. The new study implies that the clock may be much more important in living things than ...

Researchers have discovered the earliest form of human blood stem cells and deciphered the mechanism by which these embryonic stem cells replicate and grow. They also found a surprising biological marker that pinpoints these stem cells, which serve as the progenitors for red blood cells and lymphocytes.

New findings give insight into the unique characteristics of the birth defect Prader-Willi Syndrome, and at the same time, may help explain how a certain type of gene is expressed in all humans. The research finds that the amount of care a father gives to his child may cause a ...

It may take just one or two proteins to polish off a simple cellular task, but life-or-death matters, such as caring for the ends of chromosomes known as telomeres, require interacting crews of proteins, all with a common goal but each with a specialized task.

(Wiley-Blackwell) Taking 1000 mg of a specific olive leaf extract (EFLA 943) can lower cholesterol and lower blood pressure in patients with mild hypertension (high blood pressure). These findings came from a "Twins" trial, in which different treatments were given to identical twins. By doing this, researchers could increase the ...

Yale University scientists today reported evidence suggesting that the tiny cilia found on brain cells of mammals, thought to be vestiges of a primeval past, actually play a critical role in relaying molecular signals that spur creation of neurons in an area of the brain involved in mood, learning and ...
