What causes motor complications of Parkinson’s treatment? Researchers have now identified two molecules whose expression in the brain is altered in the brains of animals with side effects related to Parkinson's disease. The results may lead to new approaches to the treatment of these side effects in Parkinson's patients.

Mice whose fat cells were allowed to grow larger than fat cells in normal mice developed "healthy" obesity when fed a high-fat diet, researchers found in a new study.

Researchers have widely believed that the organic compound, allicin -- which gives the pungent vegetable its aroma and flavor -- acts as an antioxidant. But until now it hasn't been clear how allicin works, or how it stacks up compared to more common antioxidants such as Vitamin E and coenzyme Q10, which stop the damaging effects of radicals. Researchers now trace benefits to acid produced in the decomposing organic compound.

People are dying from "super bugs" because our antibiotic arsenal has run dry, leaving the world without sufficient weapons to fight ever-changing bacteria, warn infectious disease researchers.

Despite an apparent link between gum disease and preterm births, standard periodontal treatment does not decrease the risk of preterm birth. Nor is the treatment enough to halt periodontal disease progression in pregnant women, according to new research.

How are neurodegenerative diseases such as Alzheimer's initiated, and why is age the major risk factor? A recent study of a protein called MOCA (Modifier of Cell Adhesion) provides new clues to the answers of these fundamental questions.

A cell biology professor has discovered a new signal transduction pathway that might play an important role in the promotion of type 2 diabetes mellitus.

Scientists have identified new genetic sites harboring common variations in DNA that are linked to imbalances in concentrations of blood lipids (fats). The findings provide another step forward in understanding the genetic contribution to dyslipidemia, a condition marked by overproduction of low-density lipoprotein (LDL "bad" cholesterol) and triglycerides, and underproduction of high-density lipoprotein (HDL "good"cholesterol).

A new study suggests that neutralizing an acid-producing diet may be an important key to reducing bone breakdown, or "turnover," while aging. The study comes on the heels of several ARS-reported studies suggesting that consuming more-than-recommended amounts of calcium may not be the main answer to protecting bone.

Research increasingly suggests that eyewitness testimony may not be as accurate as we would like it to be. A new study examining how false information following a recall test affects volunteers' memories of a witnessed event suggests that recalled information is prone to distortion. These results suggest that the recall test may have improved subjects' ability to learn the false information -- that it enhanced learning of new and erroneous information.
