Infertility And The Battle Of The Sexes: Evolutionary Explanation For
Enzyme Complex Thought To Promote Cancer Development Can Also Help Pre In a case of basic science detective work, researchers at The University of Texas M. D. Anderson Cancer Center have solved the puzzle of the "inconsistent biomarker"and, in the process, may have discovered an agent that can suppress cancer development. Study Offers Alternative View On How Faults Form In The Ocean's Depths Scientists have long held the belief that the fracturing of the Earth's brittle outer shell into faults along the deep ocean's mountainous landscape occurs only during long periods when no magma has intruded. Challenging this predominant theory, findings from a completed study show howdifferences in mid-ocean ridge magma-induced activity produce distinctly different types of ocean floor faulting. Researchers Track Personality Traits To Learn More About Alcoholism A long-term research project at the University of Missouri-Columbia is producing valuable information about alcoholism and individuals who are affected by a family history of the disease. MU psychology researchers, now several years into a multi-year study, have discovered that individuals from alcoholic homes maintain personality traits that could eventually lead to alcohol dependency. Healthy Bodies Help Fight Disease? Clues To How Diet Affects The Immun Scientists are proposing that dietary fats can affect how well our immune system works and have discoveredthat one of the earliest steps in immune system activation relies on a molecule that binds fats. Effectiveness Of Mouse Breeds That Mimic Alzheimer's Disease Symptoms Scientists have shown that recently developed mouse breeds that mimic the symptoms of Alzheimer's disease may not be as effective as previously assumed. The scientists show that in some mouse breeds, drugs that had been shown to reduce levels of a toxic protein called amyloid beta had only minor or no effect on these mice. Important Factors Involved In The Synthesis Of Starch In Plants The classic model for explaining the biosynthesis of starch in plant leaves has been seriously called in to question. While to date the accepted belief has been that starch biosynthesis is produced solely in the chloroplast, biologist Nora Alonso Casajús' PhD provides evidence to show that the greatest part of the precursor molecule in starch biosynthesis -- known as ADPG -- accumulates in the cytosol of the plants. Can An Electron Be In Two Places At The Same Time? Max Planck Researchers in Berlin show that for electrons from nitrogen molecules, the wave-particle character exists simultaneously. System To Help Blind Navigate Environment Georgia Tech researchers are developing a wearable computing system called the System for Wearable Audio Navigation (SWAN) designed to help the visually impaired, firefighters, soldiers and others navigate their way in unknown territory, particularly when vision is obstructed or impaired. The SWAN system, consisting of a small laptop, a proprietary tracking chip, and bone-conduction headphones, provides audio cues to guide the person from place to place, with or without vision. Genome Wide Search For Genes Underlying Anxiety Disorders Turns Up Une Increasing the activity of two enzymes better known for their role in oxidative stress metabolism turns normally relaxed mice into "Nervous Nellies,"according to research conducted at the Salk Institute for Biological Studies and reported in the early online edition of Nature.
