Strategies to Kill Cancer. Stem Cell Basics: Introduction. Laboratory studies of stem cells enable scientists to learn about the cells’ essential properties and what makes them different from specialized cell types.
Scientists are already using stem cells in the laboratory to screen new drugs and to develop model systems to study normal growth and identify the causes of birth defects.

The brain is actually wired like a chess board and a new scanner reveals how in stunning detail. By Ted Thornhill Published: 10:04 GMT, 30 March 2012 | Updated: 15:31 GMT, 30 March 2012 For a long time it was thought that the brain was a mass of tangled wires, but researchers recently found that its fibers are actually set up like a chess board, crossing at right-angles.
What’s more, this grid structure has now been revealed in amazing detail as part of a brain imaging study by a new state-of-the-art magnetic resonance imaging (MRI) scanner. Van Wedeen, of Massachusetts General Hospital (MGH), who led study, said: ‘Far from being just a tangle of wires, the brain's connections turn out to be more like ribbon cables - folding 2D sheets of parallel neuronal fibers that cross paths at right angles, like the warp and weft of a fabric. What Eating Too Much Sugar Does to Your Brain. An opening against Alzheimer’s. Under normal circumstances, the tau protein is a hard-working participant in memory and brain functioning.
But in Alzheimer’s disease and other neurodegenerative diseases, tau not only ceases to play a productive role in brain health, but actually undergoes a Jekyll-and-Hyde transformation to become a misshapen villain that destroys brain cells. “Since Alzheimer’s disease takes at least a decade to develop, the major challenge to halt memory loss is to identify the initial period when the tau protein is transformed from ‘good guy’ to ‘bad guy,’” said co-senior author Kun Ping Lu (left), BIDMC investigator, who along with co-senior author Xiao Zhen Zhou, did the research.

The following is a "healthy food hot list" consisting of the 29 food that will give you the biggest nutritional bang for you caloric buck, as well as decrease your risk for deadly illnesses like cancer, diabetes and heart disease.
Along with each description is a suggestion as to how to incorporate these power-foods into your diet. Fruits 01. Apricots The Power: Beta-carotene, which helps prevent free-radical damage and protect the eyes. 02. The Power: Oleic acid, an unsaturated fat that helps lower overall cholesterol and raise levels of HDL, plus a good dose of fiber. 03. The Power: Ellagic acid, which helps stall cancer-cell growth. 04. The Power: Stop aging, live longer and keep your mind sharp with blueberries. 05.
The Power: Vitamin C (117mg in half a melon, almost twice the recommended daily dose) and beta-carotene - both powerful antioxidants that help protect cells from free-radical damage. 06. 07. Printer. Eating 10 hot dogs in 6 minutes and belching the national anthem may impress your friends, but neither of those feats will do much for your body—at least not much good. Instead, why not train yourself to do something that may actually pay off? We're not talking bench presses and interval training (though those do help).
You can teach your body to cure itself from everyday health ailments—side stitches, first-date jitters, even hands that have fallen asleep. Printer. Who came up with the idea that we are supposed to drink orange juice at breakfast?
And why, if oatmeal is so good for us, do we eat that only in the morning as well? Apologies to the Palinites, but nutritionists are starting to realize that you and I like our oatmeal and OJ before we start the day because we evolved to like it that way—because enjoying the two together is healthier than eating each of them alone. Epidemiologist David R. Jacobs, Ph.D., of the University of Minnesota calls it food synergy, and he, along with many other nutritionists, believes it might explain why Italians drizzle cold-pressed olive oil over tomatoes and why the Japanese pair raw fish with soybeans. "The complexity of food combinations is fascinating because it's tested in a way we can't test drugs: by evolution," says Jacobs.
