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.

Young adults can be motivated to eat more servings of fruits and vegetables

Young adults can be motivated to eat more servings of fruits and vegetables if they are exposed to tailored, practical messages about nutrition, a University of Wisconsin-Madison nutritional scientist announced at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington, D.C.

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.

Variation in a taste receptor gene influences taste sensitivity

Variation in a taste receptor gene influences taste sensitivity of children and adults, accounting for individual differences in taste preferences and food selection, report a team of researchers from the Monell Chemical Senses Center. In addition to genes, age and culture also contribute to taste preferences, at times overriding the influence of genetics.

Americans pay little attention to genetically modified foods

According to a national study of 1,200 Americans commissioned by the Food Policy Institute (FPI) at Rutgers-Cook College, while most Americans say they are interested in the technology and have opinions about it, most lack the tools and background needed for an informed assessment.

Melanopsin plays a key role in the inner workings of the eye

A Brown University team has found that a protein called melanopsin plays a key role in the inner workings of mysterious, spidery cells in the eye called intrinsically photosensitive retinal ganglion cells, or ipRGCs.

Theory on evolution of essential genes is overturned

A gene passed on by fathers that plays a vital role in helping fertilised eggs to develop into adults has helped scientists overturn the idea that essential genes have always been part of the genetic makeup of a species.

Added sugar in fruit-flavored drinks and cola-type soft drinks undoes the good done by vegetables

American preschoolers get about 14 to 17 teaspoons of added sugar a day, on average, mostly from fruit-flavored drinks, high-fat desserts and cola-type soft drinks which displace the grain, vegetable, fruit and dairy food groups and lower the quality of their diet, a Penn State study has shown.
